Chapter 7 Define behaviourist People that studied psychology only by looking at behaviour, not mental processes What is learning? Process of acquiring new information or behaviours through experience / a relatively permanent change in behaviour due to experience What is associative learning? Linking two events that occur close together in time Give three ways that we learn Through associative learning: Certain events occur together (classical conditioning); stimuli that are not controlled are associated and the response becomes automatic (respondent behaviour) Through consequences: Association between a response and a consequence is learned (operant behaviour) Through acquisition of mental information that guides behaviour: Cognitive learning Explain Pavlov’s dog food experiment and name the stages that represent the Unconditioned Stimulus, the Unconditioned Response, the Neutral Stimulus, the Conditioned Stimulus and the Conditioned Response Pavlov realised that if he trained a dog by repeatedly presenting dog food to a dog immediately after ringing a bell, the dog would start to salivate at the sound of the bell Unconditioned Stimulus → yummy dog food! Unconditioned Response → salivating at the dog food Neutral Stimulus → the bell Conditioned Stimulus → also the bell! But after it has been associated with the food Conditioned Response → the dog salivating at the sound of the bell Define Unconditioned Stimulus (US) A stimulus that naturally triggers a response Define Unconditioned Response (UR) A naturally occurring response to the US Define Neutral Stimulus (NS) A stimulus that has not been paired with the US and elicits no response Define Conditioned Stimulus (CS) A previously neutral stimulus (NS) that is paired with the US and as a result, triggers a conditioned response (CR) Define Conditioned Response (CR) A learned response to a previously neutral stimulus, but now a conditioned stimulus Define Higher-order conditioning / second-order conditioning A procedure in which the conditioned stimulus in one conditioning experience is paired with a new neutral stimulus, creating a second (often weaker) conditioned stimulus For example, an animal that has learned that a tone predicts food might then learn that a light predicts the tone and begin responding to the light alone. Name some uses of classical conditioning Classical conditioning can help us to expedite a response so that it occurs before the US begins Acquisition of expectancies help organisms prepare for good or bad events. Necessary for our survival from an evolutionary perspective. Act as notifications to prepare for fight or flight, or to extend pleasure Name five stages of learning / conditioning Acquisition Extinction Spontaneous recovery Generalisation Discrimination Define the Acquisition stage The association between a neutral stimulus (NS) and an unconditioned stimulus (US) We know that acquisition has occurred when neutral stimulus previously didn’t cause anything, but now it does trigger something Usually, for the association to be acquired, the neutral stimulus (NS) needs to repeatedly appear before the unconditioned stimulus (US), about a half-second before, in most cases (the bell must come right before the food). Define the Extinction stage Refers to the diminishing of a conditioned response. If the US (food) stops appearing with the CS (bell), the CR decreases. Define the Spontaneous Recovery stage After a CR (salivation) has been conditioned and then extinguished: Following a rest period, presenting the tone alone might lead to a spontaneous recovery (a return of the conditioned response despite a lack of further conditioning) If the CS (tone) is again presented repeatedly without the US, the CR becomes extinct again. Define the Generalization stage Once a response has been conditioned, generalisation would be defined as the tendency to respond in a similar way to stimuli similar to the CS (ex: a dog that is conditioned to salivate at the sound of a dinner bell may also salivate at the sound of a doorbell) Define the Discrimination stage The learned ability to distinguish between a CS and other similar stimuli that do not signal an US (discriminating between relevant and not relevant stimuli) (ex: Infants can tell the difference between their mother's voice and the voice of other women) Explain the implications of this on abuse in children A study showed that abused children’s brains respond differently to angry faces compared to non abused peers (association between anger and danger) Why do we still care about Pavlov? Most psychologists agree that classical conditioning is a basic learning form among all species and that can be studied objectively Pavlov’s principles are used to influence human health and well-being (including addiction) Pavlov’s work provided a basis for Watson’s ideas that human emotions and behaviours, though biologically influenced, are mainly conditioned responses. Explain classical conditioning relating to drug cravings Former drug users crave the drug when they are in the environment in which they took drugs or they associate with people with whom they took drugs These contexts act as CS and trigger cravings for the drug (CR) Using what we know about classical conditioning, drug counsellors advise former users to stay away from these contexts. (same with staying/going on a diet) How do advertisers often use classical conditioning? To pair already-existing positive responses with their products; to control and influence human behaviour, such as purchasing behaviour Describe the US,UR,CS, and CR in an ad attempting to associate a product with a celebrity US → Known celebrity. UR → Positive feelings. CS → Product / Brand Hoped for CR → Positive feelings towards product / brand Explain what happened when researchers present a baby with a rat toy paired with a loud noise Baby started to develop fear of rat - whenever they showed the rat, the baby started crying - association has occurred - “irrational fear” of the rat Everything that had a similar feel of the rat toy - the baby started fearing those too → generalisations Define Operant Conditioning If the organism is learning associations between its behaviour and the resulting events, it is operant conditioning. Define Thorndike’s Law of effect The Law of Effect states that behaviours followed by favourable consequences become more likely, and that behaviours followed by unfavourable consequences become less likely. If a cat is put into a puzzle box many times and subsequently gets faster at escaping, what does this demonstrate? Declining rate of seconds taken to escape over times tried → learning rate Explain how researchers used a skinner box to classically condition pigeons to “learn to read” or distinguish between cancerous and normal tissue They rewarded a pigeon with food every time that it correctly accomplished a task, teaching it to peck at the correct answer Explain shaping behaviour / how to apply classical conditioning Reinforcers guide behaviour towards the desired target behaviour through successive approximations Reward behaviour that approaches the desired behaviour Allows animal trainers to get animals to perform complex behaviours Define Reinforcer An event that increases the likelihood of a behaviour being repeated Give the six types of reinforcers Positive + negative, primary + secondary, immediate + delayed Define each of them Positive reinforcement → Presenting a rewarding stimulus after a response Negative reinforcement → Removing an unpleasant stimulus after a response (scream until daddy stops the car ad dairy queen) Primary reinforcer → an innately reinforcing stimulus, such as one that satisfies a biological need (food, sex, water) - very intrinsic, biological Secondary (Conditioned) reinforcer → a stimulus that gains its reinforcing power through its association with a primary reinforcer (stickers, money, power, etc.). Immediate Reinforcer → A reinforcer that occurs instantly after a behaviour. A rat gets a food pellet for a bar press Delayed Reinforcer → A reinforcer that is delayed in time for a certain behaviour. A paycheck that comes at the end of a week. Define continuous reinforcement, list an advantage and a fault Reinforcing the desired response every time it occurs Great for learning, prone to fast extinction Define partial (intermittent) reinforcement, list an advantage and a fault Reinforcing the desired response only part of the time Perhaps more practical in real world, slower learning, more resistant to extinction (slot machines, gambling) List four different types of reinforcement schedules and define them Fixed-ratio schedule: reinforcing the desired response only after a specified number of responses Ex. Buy 10 coffee drinks, get the 11th free (Produces high rates of responding) Variable-ratio schedule: reinforcing the desired response after an unpredictable number of responses Ex: If the slot machine sometimes pays, I’ll pull the lever as many times as possible because it may pay this time! (Produces high, consistent rates of responding) Fixed-interval schedule: reinforcing the desired response only after a specified time has elapsed. Ex. Checking for snail mail, cramming for a test (Produces a choppy, stop-start pattern of responding) Variable-interval schedule: reinforcing the desired response at unpredictable time intervals. Ex. Checking for email, Pop quiz, If I don’t know when the pop quiz will happen, I’ll study everyday (Produces slow, steady responding) Define punishment An event that tends to decrease the behaviour that it follows Explain positive and negative punishment Positive punishment → Addition of unpleasant stimulus (getting a parking ticket) Negative punishment → Removal of pleasant stimulus → (cutting down screen time) In learning and conditioning, “positive” means that something is _____ and “negative” means that something is ________. Added, taken away How does operant conditioning differ from classical conditioning? If the organism is learning associations between its behaviour and the resulting events, it is operant conditioning If the organism is learning associations between events that it does not control, it is classical conditioning Chapter 8 Explain how we measure retention (three ways) and define them Recall (free recall, like seeing someone and trying to remember their name - most difficult) Recognise (correctly identifying prev learned information - things might trigger something - multiple choice question) Relearn (speed of relearning) (riding your bike again after twenty years) (it’ll be faster than when you first learned it) (how much time / effort is saved when learning material for the second time) Explain Ebbinhaus’s memory experiment and the retention curve Ebbinghaus studied his own verbal memory. He tried to learn (memorise) a list of nonsense syllables. The more times he rehearsed the list on day one, the less time it took to memorise the list on day two. Speed of relearning is one measure of memory retention - when relearning, it will be memorised more easily, accurately, and rapidly. What can we learn from this experiment? We retain more when our learning involves more time and repetition. Tests of recognition, and tests of time spent relearning, demonstrate that we remember more than we can recall - we can recognise things that we couldn’t just simply remember, and things will jog our memories( ex: solving a puzzle, remembering lyrics of a song with and without background music, name all the marvel movies you have watched). Explain the three stages of the information processing model, and what it compares the human brain to Compares human memory to computer operations Involves three processes: Encoding: the information gets into our brains in a way that allows it to be stored Storage: the information is held in a way that allows it to later be retrieved Retrieval: reactivating and recalling the information, producing it in a form similar to what was encoded Explain connectionism Focuses on multitrack, uses parallel processing Views memories as products of interconnected neural networks Define Atkinsons and Shiffrin’s three stage model (the original one) External events happen, and then: Sensory input from the environment is recorded as fleeting sensory memory. Information is processed in short-term memory. Information is encoded into long-term memory for later retrieval. Give some shortcomings of the three-stage model Cannot explain why we forget things. Cannot explain why different people experiencing the same events remember different details and aspects of it. Explain Atkinson-Shiffrin model’s updated concepts Working memory: We can’t focus on all the sensory information we receive, so we select information that is important to us and actively process it into our working memory Includes visual and auditory rehearsal of new information Part of the brain functions like a manager, focusing attention and pulling information from long-term memory to help make sense of new information Considered a central executive unit :) Automatic processing: To address the processing of information outside of conscious awareness Some information skips the first two stages and enters long-term memory automatically. What part of the brain is responsible for episodic memory? The hippocampus Explain the differences between explicit and implicit memory Dual-Track memory system divides our memory into conscious and unconscious tracks. Explicit memory - conscious, explicit, declarative memories are facts and experiences that we can consciously know and declare. We encode explicit memories through conscious, explicit, sequential, effortful processing. Implicit memory - Unconscious, implicit, nondeclarative memories are facts and experiences that are formed through automatic processes and bypass conscious encoding track – we don’t exert effort, and are not even aware that they are happening. What information do we process automatically? Implicit memories include automatic skills and classically conditioned associations. Information is automatically processed about: Space: while reading a textbook, you automatically encode the place of a picture on the page Time: we unintentionally note the events that take place in a day Frequency: you effortlessly keep track of how often things happen to you We are not consciously trying to remember these details, but they are automatically encoded in our memories. With experience and practice, some explicit memories become automatic. Examples: driving, texting, and speaking a new language (teaching nonsensical characters as a language in an experimental setting) Explain Sperling’s Iconic Memory Experiment Sperling flashed letters on a screen for 1/20th of a second. He asked people how many letters they recalled. Participants could recall only ½ of the letters. Next, Sperling flashed the letters on a screen for 1/20th of a second. Immediately after the screen went blank, he sounded a tone. A high, medium, or low pitch tone signaled the row that participants were to report. Recall for letters in a row was almost perfect. How can we explain this result? What happens when the tone sounds? When the tone sounds right after the picture is flashed, we have time to retrieve the letters from iconic memory. What is the Briefest Form of Memory Storage Sensory Memory The immediate, initial recording of sensory information in the memory system Define echoic and iconic memory, and explain how long they last Iconic Memory - visual sensory memory → Duration: less than a second Echoic Memory - auditory sensory memory → Duration: a few seconds What type of memories are the hippocampus and frontal lobes responsible for? Processes explicit memories for facts and episodes Hippocampus: Registers and temporarily holds elements of explicit memories before moving them to other brain regions for long-term storage. Two types: Semantic memory: meaning of words, grammar of a language, concepts, abstract ideas that we learn through school - more abstract / concepts / semantically learned -hunger, kindness, etc Episodic memory: memory of snapshots of our life that together - movie like, form episodes What has been noticed about the hippocampus in dementia patients It is often smaller than average Explain which type of memories the right and left hemispheres process Left hemisphere → more numerical, semantics, verbal Right → more episodic Explain the London taxi drivers experiment Central London Taxi Drivers spend 3-4 years learning “the knowledge.” Failure rate for exam: 50% They found that the longer someone had been a taxi driver, the larger their rear area of hippocampus (involved in spatial ability) Follow up study: Assessed participants before and after training Three groups: Ps who succeeded and passed the exam, those who had failed the exam, and a control group Replicated findings: Those who succeeded had an increased hippocampal volume; no difference in other two groups What part of the brain is responsible for implicit memory? The cerebellum and the basal ganglia Explain some features of the cerebellum, what happens if it is damaged, and if it is considered unique to humans Plays a key role informing and storing the implicit memories created by classical conditioning. Also big on coordinating movement, balance, attention and eye movement. Damage to cerebellum disrupts forming conditioned reflexes. Part of the initial brain structures (“little brain”, or “lizard brain”) that exist in other species as opposed to more advanced and high-level areas like the PFC. Explain what functions the basal ganglia has Deep brain structures involved in motor movement Facilitate formation of our procedural memories for skills What type of memory does the amygdala take care of? Emotion-related memory formation Overall: Frontal lobes and hippocampus: explicit memory formation → Semantic and episodic memory - facts and general knowledge, personally experienced events Cerebellum and basal ganglia: implicit memory formation → Space, time, frequency, classical conditioning, motor and cognitive skills Amygdala: emotion-related memory formation How do external cues and priming influence memory? Act as a Retrieval Cue: Will activate existing memory by a stimulus and that activation often unconsciously results in activation of particular associations in memory Give an example from class of priming that influences memory Showing a rabbit and a bunny, and then asking us to remember how to spell hare - volunteer spelt it the less common way that was related to the priming What is an everyday example of us using priming to help our memory without knowing? When you lose a key, you go to the room where you last saw it, hoping that what you see triggers your memory → “this’ll jog my memory!” Explain context-dependent memory Our ability to recall is improved when we are in the same context that the initial experience occurred. Encoding specificity principle: cues and contexts specific to a particular memory will be most effective in helping us recall it. Explain why we would probably do better on our psych exams if we did them in the pool Context dependant memory - trying to recall information in the same environment that we learned it in would help us to remember it Explain the diver memory experiment Recall of words was a lot stronger when the participant was in the place that they learnt the words - if a diver learnt them underwater, recall was stronger there than on the beach, and vise versa Explain state-dependant memory Recall is improved when encoding and retrieval of a memory happen in the same emotional or biological state. Explain state-dependant memory’s impact on depression It is difficult to remember happy times when depressed Explain how memory of period pain changed when the person reporting it was in pain Women reported remembering higher pain levels in the past compared the pain levels that were reported during painful episodes if they were experiencing pain at the time of remembering Explain the “how much do you like this class” survey Students were asked how much they agreed with these statements, once after receiving their midterm results, and once after they were given a chance to boost their grade with a bonus activity. Results showed that students more strongly agreed that they had a pleasant experience in class after they had a positive experience (bonus activity) compared to after they had a negative experience (test results). Sometimes, how we think we feel about something depends partially on how we feel about _____________ at that moment and could have less to do with the objective quality of the thing we are looking at. Ourselves and our life Explain Encoding Failure When input is present too quickly, before we have enough time to process it, encoding, storing, and later retrieving the images becomes harder. We are more likely to remember the first and the last images. Encoding failure → retrieval failure, since we can’t remember what we have not encoded. Explain the two serial position effects and some possible explanations for it Our tendency to recall best the last (recency effect) and first (primacy effect) items in a list Recency effect p-ossible explanation: The last items may be held in short-term memory. Primacy effect possible explanation: The attention is on the first items. Short-term memory doesn’t help in this case because there is a long delay. Define reconsolidation A process in which previously stored memories, when retrieved, are potentially altered before being stored again Give two sources of errors in memory (contributing to false memories) Misinformation effect: when misleading info has corrupted one’s memory of an event Source amnesia: failed memory for how, when, or where information was learned or imagined (unintentional plagiarism) Watch videos - no qs yet What was the difference in answers when people were asked if there was glass at a scene where cars hit vs smashed? People that were asked with the word smashed were more likely to “remember” glass at the scene, even though there wasn’t any there Explain the effect of false memory on eyewitness testimony Eyewitness testimony can be extremely unreliable - the way that questions are asked, suspects are presented, etc. can alter someone’s memory and can cause people to accuse with certainty the wrong person Chapter 9 How do pictures affect our answers to true/false questions? When given a statement and asked if it is true or false, we are more likely to say True if the statement is accompanied by a picture, even when the picture gives us no clue to the truthfulness of the statement. Explain the difference between misinformation and disinformation Misinformation refers to false information that is not intended to cause harm. Disinformation refers to false information that is intended to manipulate, cause damage and guide people, organisations and countries in the wrong direction. Explain how this could be used in media News - disinformation + misinformation: can include suggestive words or images to influence people’s memory Define Intuition An effortless, immediate, automatic feeling or thought, as contrasted with explicit, conscious reasoning Define cognition All the mental activities associated with thinking, knowing, remembering, and communicating. Can include: How we use mental images Create concepts Solve problems Make decisions and form judgments Define concepts or grouping Mental groupings of similar objects, events, ideas or people Why are they useful? Concepts provide a kind of mental shorthand, economising cognitive efforts by minimising the computational load Reduce communication time by referring to category name rather than specific name of objects in the category (ex chair instead of specifically referring by name to every chair type) What do we form when learning concepts? Prototypes Define prototype a mental image of best example that incorporates all the features we associate with a category (ex robin vs penguin - both birds, but a robin fits our prototype better) When do prototypes fail? Examples stretch our definitions (is a stool a chair?) The boundary between concepts is fuzzy (categorising a colour when it is between blue and green) Examples contradict our prototypes (is a whale a fish? is a whale a mammal? Does it mean it is not a fish?) Explain how prototypes help and are dangerous when it comes to heart attacks Prototypes of heart attacks may make it easier for people to recognise quickly when they are happening… but only when the heart attack matches the well known prototype. If a heart attack presents in an unusual way that doesn’t fit the prototype, it is more likely to be missed or dismissed Explain how prototypes can relate to discrimination and the bike stealing experiment People form prototypes of the “types of people” that they think would do certain things - people associated a black man with being likely to steal a bike and stopped him, called the police, etc. For a white man, only one couple stopped him and did something about it. For a white woman, someone offered to help her. What cognitive strategies assist problem solving? Define them, suggest when they are most useful/unuseful and give an example Trial and error → no slide for this one? Algorithms → strategy that involves following a specific rule, procedure, or method that inevitably produces the correct solution - useful because they inevitably produce a result but often take a long time (ex: searching every shelf in a grocery store for something) Heuristics → strategy that involves using a mental shortcut to reduce the number of solutions - usually speedier, but more error-prone than algorithms (make judgments and solve problems efficiently) (when looking for apple juice, you narrow your search to the beverage, natural foods, or produce sections of the supermarket (you check only the related aisles)) Insight → a sudden, often novel, realisation of a solution. The “Aha”moment. Contrasts with strategy-based solutions (when looking for apple juice, you suddenly realise you are in a type of store that wouldn’t sell apple juice. You need to head to another store). What interferes with our problem solving abilities? Confirmation bias Fixation Mental set Imposing constraints Define confirmation bias a tendency to search for information that supports our preconceptions and to ignore or distort contradictory evidence. Once people form a belief, they prefer belief-confirming information Explain how confirmation bias impacted the divorce custody experiment we talked about in class (usually): When people were asked who they would award sole custody of a child to, they focused on the positive traits, and when they were asked who they would deny sole custody to, they focused on the negative traits - usually leading to people denying and awarding custody to the same parent Define fixation The inability to see a problem from a fresh perspective Sometimes you may see a pattern and continue to use that pattern, not seeing an easier solution Kind of the opposite of out of the box thinking Define switch cost The cognitive effort associated with switching from one task to another. Switch cost is ______ when switching from a difficult task to a simple task compared to switching from an easy task to a difficult task. Higher Define mental set A tendency to approach a problem in one particular way, often a way that has been successful in the past. Example of fixation. Impose constraints (not in your book) The tendency to assume that there are extra constraints in a task Define Availability Heuristic and give an example We judge things based on how quickly the information comes to mind / the tendency to estimate the frequency of an event by how readily it comes to mind ex: Which of the following causes more deaths in the United States each year? Stomach cancer or drunk driving accidents? People who say A : 38% , people who say B : 62% BUT stomach cancer actually causes more deaths. Car accidents are reported more in the press → increased vividness Define Framing and give an example Framing is the way an issue is posed → how an issue is framed can significantly affect decisions and judgments Framing draws our attention to some aspects of the available information over others. With gains, we prefer certain options and with losses, we prefer uncertain options Ex: Imagine Canada is preparing for the outbreak of a foreign disease, expected to kill 600 people → programs were inversely favoured based on if they were framed as saving x number of people or killing x number of people Define Anchoring and give an example Anchoring or focalism is a cognitive bias where an individual depends too heavily on an initial piece of information offered (considered to be the "anchor") when making decisions. Ex: Under time pressure, estimate: A. 8*7*6*5*4*3*2*1 or B. 1*2*3*4*5*6*7*8. Given A, people estimate roughly 3,000. Given B, people estimate roughly 500. They anchored to the first numbers Define Overconfidence and give an example Tendency to be more confident than correct – to overestimate the accuracy of our beliefs and judgments Define Belief Perseverance and give an example clinging to one’s initial conceptions after the basis on which they were formed has been discredited

Module 5 : Morphology: The World of Words •Words are an important component of our mental grammar in our linguistic knowledge. •Our knowledge of words constitutes a dynamic system in which we continually create new words and even expand their meanings into new areas. •Words encourage us to creatively use the language. Morphology is the study of the internal structure of words and the rules governing their formation in a language. Developing an understanding of morphology would enable language learners to understand how words enter a language, what they consist of, and how prefixes, suffixes, and roots are combined to form them. Recent researches indicate that learners with knowledge of word-forming processes appear to have greater vocabulary and improved understanding of reading (Kefir and Lascaux, 2008; Kefir and Lascaux, 2012a/2012b), and better writing by extension. Morphology may also be a valuable teaching method to creatively build and use vocabulary for learners. WORDS AND THEIR STRUCTURE • A child of six who starts school knows as many as 13,000 words, according to Pinker (1999, p. 3), and this number rises remarkably fast as he or she becomes exposed to new words around them from spoken language and print media. • A typical high school graduate knows about 60,000 words; We should understand that, during our lives, we all learn new terms. In short, someone who has mastered a language has also learned a remarkably enormous “list of facts coded in the form of words” (Akmajian et al. 2010). Although not a complete one, this long list of words for every language called the lexicon (or mental dictionary), is an essential part of our linguistic knowledge. • Acquaintance of a word is correlated with various kinds of information encoded in our mental dictionary. We may list the categories of knowledge we have mastered regarding a word as follows: 1.Pronunciation and Meaning - For every word we know, we have learned a sound (pronunciation) and a meaning. Each word consists of a unit of sound value, so every word in our lexicon is stored together with a pronunciation and a meaning. A random association between sounds and meanings is often present based on chance rather than being designed or based on reason. Consequently, words with the same spelling and different meanings (e.g. bare and bear) and words with the same meaning and different sounds (for example, sofa and couch) can be found. 2. Grammatical Category - Other details about a word is also stored, such as whether it is a verb, a Noun, an adjective, an adverb, a conjunction, or a preposition. Such information identifies the grammatical class of the word. For example, according to our understanding of its grammatical or syntactic class, in the sentences ‘I love Jinky’ and ‘Jinky is the love of my life’, the word love is a verb and a noun, respectively. We would not know how to create grammatically correct sentences unless we had that knowledge in our mental dictionary. 3. Orthography / Spelling - Any literate speaker of a language also stores information on how the words they know are spelled. But not every speaker knows, or has to know, the etymology of a word he or she understands. We can often speak about the roots and background of terms like coffee or yogurt in everyday life, but this sort of contextual information embedded in our mental lexicon is not really indicative of our word knowledge. CONTENT WORDS AND FUNCTION WORDS -Basically, there are two classes of words: content words and function words (also referred to as open-class words and closed-class words) English words uncle, manage, huge and rapidly are examples of content words. They belong to the major parts of speech that repcontent words and function words present ideas, actions, objects, and attributes (nouns, verbs, adjectives, and adverbs, They are often referred to as open-ended or open-class terms since we can add new words to this word class frequently. Content Words Function Words Nouns – table, small, serenity, dog Verbs - jump, swim, talk, go Adverbs -quickly, happily, blankly Adjectives - fast, big, untidy, pretty Articles - a/an, the Auxiliaries - can, will, might, must Demonstrative - this, these, that, those Quantifiers - few, many, little, some, most Prepositions -in, on, with, from Pronouns - he, she, they, we Conjunctions - and, but, or) Function words are those that do not have clear lexical meanings or obvious related concepts. They are lexically unproductive and usually invariable in form and are also called closed class. They belong to grammatical or function classes consisting of a limited number of fixed items, such as articles, demonstratives, quantifiers, prepositions, and conjunctions. unlike content words, these function words denote grammatical relations and have little or no semantic content. Basically, their function is to grammatically indicate whether a noun is definite or indefinite (the teacher or a teacher). Similarly, the word and grammatically functions as a connector of words and phrases, as in the combination of noun phrases the stars and the moon. In short, many new words such as nouns and verbs are likely to be encountered by language. • Grammars of English also give a traditional list of word classes under the name of parts of speech: verb, noun, adjective, adverb, preposition, conjunction, pronoun, article, and interjection, following an approach that goes back to Latin. In language studies, we often need to talk about parts of speech so that we can make general and economical statements about the way the words of a language behave (Crystal, 1996, p. 206). For example, “A noun is a word that is used for naming a person, thing or concept.” You might refer to Çelik (2007, pp. 92-93) and crystal for detailed characteristics of English parts of speech. THE TIE –BACK • Understanding of a word includes different kinds of information we encode in our mental lexicon. When we say we know a word, we not only know the meaning or multiple meanings of it and its pronunciation, but we also know its spelling or orthography and grammatical category such as noun or verb. Any typical English dictionary should give at least a lexical entry information that contains spelling, standard pronunciation, definitions to represent one or more meanings of the word, and parts of speech. An average dictionary may also give additional information about the etymology of words, whether the word is nonstandard (such as ain’t) or slang, vulgar, or archaic. Module 6 : Classification of Morphemes • Word forms may include a Number of units. • Plays, player, played and playing can be split into units; they are made up of one unit (play), and a number of other elements (like -s, -er, -ed, and –ing). All these elements are called morphemes, the minimal units of meaning or grammatical function that are used to form words. We may presume from this description of a morpheme that units of meaning include forms like play and units of grammatical function include elements used to show tense or plurality. • In the news headline “Shopping center in San Juan reopens; the word reopens contains three morphemes.: open is a minimal unit of meaning, re- is another minimal unit of grammatical function that means “again”, and –s is the another minimal unit of grammatical function that marks agreement with singular third person. Another example is auditors. There are three morphemes in the word auditors: audit, –or, (agentive, ‘person who does something’), and -s (indicating plurality). • One or more morphemes may represent a single word: One morpheme gentle Two morphemes gentleman (gentle + man) Three morphemes gentlemanly (gentle + man + ly) Four morphemes gentlemanliness (gentle + man + li + ness) More than four Morphemes - Ungentlemanliness (un + gentle + man + li + ness) •A single sound may represent a morpheme. For example, the morpheme a, meaning “without” as in amoral, is composed of a single sound. A morpheme may also consist of a single syllable, such a pink and –ish in pinkish, and two or more syllables, as in paper (two syllables), and crocodile (three syllables). •Morpheme as a constant meaning. For example, the morpheme –er means “someone who does” as in words like painter, teacher, and singer. However, there is also the comparative morpheme –er, meaning “more” as in faster. Thus, the same sounds may represent more than one morpheme, meaning that different morphemes may be homophonous or pronounced identically. Free and Bound Morphemes Morphemes into two broad classes from the example given above: free morphemes and bound morphemes. A free morpheme can stand alone as an independent, single word such as open and visit. A bound morpheme cannot normally stand alone and must be attached to another form. For instance, the plural morpheme -s can only ccur and make sense when it is attached to nouns, or the past tense -ed morpheme must be attached to verbs. • All affixes in English are bound morphemes, including prefixes attached to the beginning office another morpheme (like re- in reinvent,), and suffixes attached to the end of another morpheme (such as -or in auditor, inventor, director). Some bound morphemes (e.g. cran-) are called “bound base morphemes” and they are not meaningful in isolation but have meaning when combined with other morphemes. For example, cran- must occur with berry (cranberry). • Not all bound morphemes are affixes or bound bases. For example, in English forms such as ’ll, as in the sentence ‘I’ll take coffee, please’, ’ll is the contracted or shortened form of the auxiliary will. Thus, the term ‘ll is a bound morpheme and cannot stand as an independent word and must be attached to the preceding words (as in I’ll). Other contractions in are ’re (the contracted form of are, as in ‘They’re coming this afternoon) These contracted forms are bound morphemes. • There are two other sorts of affixes that you will encounter, infixes and Circumfixes. Both are classic challenges to the notion of morpheme. -Infixation is common in Southeast Asian and some Native American languages. Some linguists say that o in speed-o-meter and bar-o-meter, in Sister-in-law or mother-in-law, and a in now-a-days are infixes. • The plural morpheme -s placed internally in words like mothers-in-law or passers-by is also interpreted like an infix-like element (Trask, 2000). But it seems that English has almost no true infixes. Inserting morphemes within other morphemes is not a productive process of affixation in English. MODULE 6 TABLES. • Circumfixes are affixes that come in two parts. One attaches to the front of the word, and the other to the back. Circumfixes are controversial because it is possible to analyze them as consisting of a prefix ad a suffix that apply to a stem simultaneously. •Like infixes, the existence of circumfixes challenges the traditional notion of morpheme (but not the definition used here) because they involve discontinuity (either in the word or in the affix.) Lexical and Functional Morphemes • All free morphemes can be divided into two classifications: lexical and functional morphemes. English lexical morphemes consist of nouns, verbs, adjectives, and adverbs that all communicate the content of the messages speakers want to convey. Student, teacher, invest, save, quick, happy, and Honestly are examples of such lexical morphemes. Since we can add new lexical morphemes to English and other languages, they are also described as content words or open class of words. (Çelik, 2007, p. 94). • Functional morphemes primarily include functional English word like articles, prepositions, conjunctions, quantifiers, and pronouns. They are regarded as a closed class of words. To sum up, the meaning of lexical morphemes in and of themselves can easily be understood, but the meaning of functional morphemes can only be comprehended when they are used in a sentence with other words. Derivational and Inflectional Morphemes • English bound morphemes into two: derivational and inflectional morphemes. Derivational morphemes are used to create new words or to “make words of a different grammatical class from the stem. For example, the addition of the derivational morpheme -ize changes the adjective normal to the verb normalize. Likewise, we can derive the adjectives helpful and helpless by adding the derivational morphemes -ful and -less to the noun help. Derivational morphemes are a powerful means of word formation in English. • Inflectional morphemes are used to show some aspects of the grammatical function of a word. They may indicate if a word is singular or plural, whether it is past tense or not, or whether it is a comparative, superlative, or possessive form. In fact, inflection exists in many languages, but compared to other languages of the world, there is relatively little inflection in English. At present, there are only eight inflectional morphemes in the English language. Table 2.2 Inflectional Morphemes of English English inflectional morpheme Grammatical function Example s/ -es marks as more than one added to nouns plurality "When you play the game of thrones, you win or you die. There is no middle gound.” ’s marks for ownership added to nouns possessiveness "They say night’s beauties fade at dawn, and the children of wine are oft disowned in the morning light. er marks for comparison, added to adj comparative “Fear cuts deeper than swords.” est marks as superlative, added to adj superlatives “Some old wounds never truly heal, and bleed again at the slightest word. s marks to agree with singular third person added to verb "'A reader lives a thousand lives before he dies,' said Jojen.’ The man who never reads lives only one.'" d/-ed marks past tense verb "We are only human, and the gods have fashioned us for love. That is our great glory, and our great tragedy." Ing Marks present Participle Verb "The storms come and go, the big fish eat the little fish and I keep on paddling." n/ -en marks past participle “And I have a tender spot in my heart for cripples and bastards and broken things.” •Differences between inflectional and derivational morphemes: - First, inflectional morphemes can never alter the grammatical Category (part of speech) of a word. For example, tall and taller are both adjectives. The inflectional morpheme -er (comparative marker) simply creates a different version of the adjective tall. On the other hand, derivational morphemes often change the part of speech of a word. Thus, the verb read becomes the noun reader when we add the derivational morpheme -er. However, some derivational morphemes do not change - Second, when a derivational suffix and an inflectional suffix are added to the same word, they always appear in a certain relative order within the word. That is, derivational suffixes come first, followed by inflectional suffixes. Thus, the derivational -er is added to read, then the inflectional (-s) is attached to produce readers. When an inflectional suffix is added to a verb, we cannot add derivational suffixes any further. It is impossible to have a form like legalization, with inflectional -s being followed by the derivational -ation because inflectional morphemes occur outside derivational morphemes and attach to the base or stem. For these reasons, derivational Morphemes show the “inner” layer of words, whilst inflectional suffixes mark the “outer” layer of words. - A third point worthy of being emphasized is that certain derivational morphemes function to create new base forms or new stems to which we can attach other derivational or inflectional affixes. Say, we use the Derivational -atic to make adjectives from nouns, just like in words systematic and problematic. Then, we can further add -al to these two words to create systematical and problematical. Similarly, the derivational suffix -ize is often added to create verbs from adjectives, as in modernize, and we can add the inflectional suffix -s (modernizes) to such -ize verbs. To wum up, we can say that certain derivational affixes create new words for a given class, but inflectional affixes are always added to existing words of given class. Some Exceptions in English Morphology • Some nouns form their plurals irregularly. Typical examples of such irregular plurals in English are knife – knives, ox – oxen, goose – geese, and child – children. There are also exceptions in the forms of the past tense verbs in English, like the words began (begin), broke (break), went (go), and ran (run). Both historical influences and the effect of borrowed words play a role. in accounting for such irregularities.
