Chapter 6: Learning
Learning: Acquiring new, relatively permanent information or behaviors.
Associative Learning: Forming connections between events.
Classical Conditioning: Linking two stimuli to anticipate events.
Operant Conditioning: Associating behavior with consequences.
Cognitive Learning: Learning through observation and mental processes.
Classical Conditioning
Ivan Pavlov: discovered classical conditioning by showing how animals can link a neutral stimulus with a significant one.
Neutral Stimulus (NS): Evokes no response before conditioning; Unconditioned Stimulus (US): Naturally triggers a response; Unconditioned Response (UR): Natural reaction to US; Conditioned Stimulus (CS): Previously neutral, now triggers response; Conditioned Response (CR): Learned reaction to CS.
[Understand the relationship between them, use the flow chart from slides]
Major conditioning process:
Acquisition
Extinction
Spontaneous recovery
Generalization (stimulus generalization)
Discrimination
Operant conditioning
The consequences of a behavior change the likelihood of a behavior’s occurrence (actions followed by rewarding/punishing event increase/decrease behavior)
Thordike’s Puzzle Box (1989)
Law of Effect: Behaviors followed by satisfying outcomes are more likely to recur, while behaviors followed by unsatisfactory outcomes are less likely.
Operant Chamber
By B.F. Skinner: founder of behaviorism, believed that mechanism of learning were the same for all species
Pigeon superstitions: what is the experiment?
Superstitious behavior: response that is accidentally reinforced
Shaping: procedure which reinforcers guide behavior closer and closer to a desired behavior (rewarding desired behaviors and ignoring all other responses)
Reinforcement: positive/negative
Schedules of reinforcement: fixed/variable ratio; Fixed/Variable interval
[learn to distinguish them; how each of them shows a relationship between time and cumulative responses]
Punishment: positive/negative
Influences on Conditioning
Biology and cognition limit the range of behaviors that can be conditioned
Biological constraints: predisposes organism to learn behaviors that are evolutionarily adaptive.
Cognition: Behaviorism underestimated the effects of cognitive processes on learning
Purposive behavior: most behavior is goal-directed– if we only consider rewards and punishments, we might miss underlying reasons why people do things
Tolman’s cognitive maps: rats exploring maze
[what is the experiment? What’s the conclusion/implication?]
Observational learning
Modeling: attention/retention/motor reproduction
Reinforcement: vicarious reinforcement/punishment
Chapter Questions:
Q: How do continuous and partial reinforcement schedules affect behavior?
Q: What limits does biology place on conditioning?
Q: What roles do acquisition, extinction, spontaneous recovery, generalization, and discrimination play in classical conditioning?
Chapter 7: Memory
Memory
The process of retaining, retrieving, and using information about past events, stimuli, or skills.
Modal Model of Memory
Atkinson and Shiffrin, 1968
[What are structural features? What are Control Processes? Do they interact with each other?]
Sensory Memory
Holds all information; less than a second long - brief retention of stimuli
visual/auditory; Iconic/Echoic
Initial experiments about visual sensory memory
Sperling (1961): sensory memory has a large capacity but decays rapidly.
Short-Term Memory (STM)
Holds information for 15-30 seconds
Capacity: limited to 5-9 items
Digit Span: A measure of STM capacity by recalling numbers in a sequence.
Rehearsal: repetition to prolong STM duration
Chunking: Grouping items into meaningful units to expand capacity.
Encoding
The process of storing information in LTM.
Types: Automatic/Effortful Encoding
Levels of Processing: a continuum from shallow to intermediate to deep encoding of a stimulus
Long-Term Memory (LTM)
Declarative (Explicit) Memory: facts and events
Semantic/Episode Memory
[distinguish examples from each of them]
Retrograde/anterograde amnesia
Nondeclarative (Implicit) Memory: unconscious memories, often automatic
Procedural Memory: Skills and tasks
Link exists between semantic and procedural memory
Retrieval: People report memories as constructions of what they experienced
Recall
Generating information from memory without cues.
Generate + Recognize
Free/Cued Recall
Recognition
Identifying information without producing it
Retrieval Cues
Context-Dependent Learning
State-Dependent Learning
Roediger and Karpicke (2006)
Which is better study technique (rereading or retrieval practice?)
Forgetting
3 reasons for forgetting
Information never encoded
Information completely erased from memory
Decay
Information still in LTM, but inaccessible
Interference: proactive/Retroactive
Retrieval failure
Misinformation Effect
Loftus & Palmer (1974): wording (e.g., “smashed” vs. “hit”) can change memory recall of car crash speeds.
False Memories: Constructed memories influenced by suggestions or prior associations.
Study and Retrieval Techniques
Distributed Practice: Spacing out study sessions over time.
Testing Effect: Practicing retrieval improves memory better than rereading.
Chapter Questions:
Q: What is a retrieval cue?
Q: Why is cramming for an exam ineffective, and what is a more effective study method?
Q: How do misinformation, imagination and source amnesia influence our memory construction?
Chapter 8: Thinking and Language
Key terms
○ Cognition: how information is processed and manipulated when remembering, thinking, and knowing
■ thinking:Manipulating information mentally by forming concepts, solving problems, making decisions, and reflecting in a critical or creative manner
○ concept: mental representation of a class/individual; categories of objects, events, abstract ideas
Categorization
○ prototype theory: one object is a “prototype” for each category; one object represents a category
■ includes graded membership (more or less)
■ includes typicality (high or low)
Decision Making
○ reasoning: process of drawing conclusions
○ judgment: assessment of the likelihood of a given event occurring on the basis of incomplete information
○ decision making: making a selection from a variety of options
Heuristics
○ availability heuristic: frequency of a given event is estimated on basis of how easily information about the event can be accessed
■ can lead to stereotypes
○ representativeness heuristic: an object belongs to a category because it is representative/typical of that category
○ base-rate information: relative frequency with which an event occurs in the population
○ base-rate neglect: paying insufficient attention to the true frequency of an event
○ confirmation bias: looking for information that confirms beliefs, ignoring information that refutes beliefs
Problem solving heuristics
○ hill-climbing strategy: at every point, choose the option that moves in the direction of your goal
Creativity
○ functional fixedness: inflexible focus on the usual function(s) of an object in problem solving
○ Four stages of the creative process:
■ preparation: gather information about problem
■ incubation: set problem aside; work on it unconsciously
■ illumination: key insight or new idea emerges
■ verification: confirm new idea will solve problem
Language
○ hierarchical organization: from smallest unit to the largest unit (phoneme, morpheme, word, sentence)
○ rule-based nature: components can be arranged in certain ways but not in others
○ Characteristics of language:
■ generative- can combine symbols in infinite ways
■ semantic- symbols are used to convey meaning
■ arbitrary- symbols don’t directly map onto a meaning
■ displacement- ability to talk about things that are distant in time/space
○ Linguistic relativity hypothesis: the language we speak determines the way we think
Phoneme perception
○ context cues: using information about a sound’s acoustic context to infer what sound you’re hearing
○ phoneme restoration effect: when a predictable phoneme within a word is replaced with a non-speech sound, people will hear both
■ top-down processing
○ statistical learning: infants notice patterns in speech stimuli and analyze those patterns to identify subcomponents
Conversations
○ given-new contract: statements should contain both given and new information for communication to be successful
○ common ground: mental knowledge and beliefs shared among conversational parties
Bilingualism
○ Sequential and Simultaneous bilingualism
○ Advantages: executive functions
■ Why?
○ Disadvantages: 2 mental dictionaries
Animal Communication
○ How do bees communicate nectar distance/location/quality?
■ Similarities/differences with human communication
○ How do vervet monkeys communicate information about predators?
■ Similarities/differences with human communication
○ Washoe the chimpanzee
■ Training method
■ Sign capabilities
○ Differences between how humans and apes use signs
■ Syntactic differences
■ Social differences

Q: How do infants take advantage of the statistics of language to identify words in speech?
Q: What is insight and how does it facilitate problem solving?
Q: How is an algorithm different from a heuristic?
