Unit 5 AP Psychology Cognition and Intelligence

9-1: What is cognition, and what are the functions of concepts?

Cognition refers to the mental processes involved in gaining knowledge and comprehension, including thinking, knowing, remembering, and judging. Concepts are mental categories that help organize information and enable efficient processing, allowing individuals to recognize, differentiate, and relate objects or ideas. The functions of concepts include simplifying interactions with the world, facilitating communication, and supporting problem-solving by categorizing experiences and guiding expectations.

Cognition

Cognition refers to the mental processes involved in acquiring knowledge and understanding through thought, experience, and the senses. Functions of concepts include facilitating communication, organizing information, and enabling efficient problem-solving.

Concept

A mental representation used to categorize and organize information, aiding in understanding and communication.

Prototypes

Cognitive representations of the typical or ideal example of a concept, used to understand and categorize new instances.

Metacognition

The awareness and understanding of one's own thought processes, including self-regulation and reflection on how one learns.

9-2: What cognitive strategies assist our problem solving¸and what obstacles hinder it?

Cognitive strategies such as algorithms and heuristics assist in problem-solving by providing systematic approaches or shortcuts, while obstacles like confirmation bias and fixation can hinder effective problem-solving. Confirmation bias refers to the tendency to search for, interpret, and remember information in a way that confirms one's preconceptions, while fixation is an inability to see a problem from a fresh perspective.

Algorithm

A step-by-step procedure or formula for solving a problem, guaranteed to produce a correct solution if followed correctly.

Heuristics

Mental shortcuts or rules of thumb that simplify decision making and problem solving.

Insight

A sudden realization of a problem's solution, often experienced as an "aha!" moment that involves the restructuring of information.

Confirmation bias

The tendency to search for, interpret, favor, and recall information in a way that confirms one's preexisting beliefs or hypotheses.

Fixation

A mental block that inhibits a person from seeing a problem from a fresh perspective, often preventing creative solutions.

Mental set

A tendency to approach problems using a previously successful strategy, which may hinder problem-solving if the situation changes.

Schema

A cognitive framework or concept that helps organize and interpret information in the brain. Schemas enable individuals to process new information by relating it to existing knowledge.

Assimilation

The process of incorporating new information into existing schemas without changing the schema. Assimilation allows individuals to make sense of new experiences by fitting them into what they already know.

accomodation

The process of modifying existing cognitive schemas or creating new ones to incorporate new information. Accommodation allows individuals to adjust their understanding when new experiences or information contradict their prior concepts.

Functional fixedness

A cognitive bias that limits a person to using an object only in the way it is traditionally used, hindering problem-solving and creativity.

Executive functions

A set of cognitive processes that include working memory, flexible thinking, and self-control, enabling individuals to plan, focus attention, and manage multiple tasks.

9-3: What is intuition, and how can the availability heuristic and representativeness heuristics influence our decisions and judgments?

Intuition is the ability to understand something immediately without the need for conscious reasoning. The availability heuristic influences decisions based on how easily examples come to mind, while the representativeness heuristic relies on the similarity of an object or event to a prototype, potentially leading to biased judgments.

Intuition

is the ability to know something instinctively, often without conscious reasoning, allowing for quick decision-making.

Representativeness heuristic

A cognitive shortcut used to judge the probability of an event by comparing it to an existing prototype or stereotype, which may lead to errors in reasoning.

Availability heuristic

A mental shortcut that relies on immediate examples that come to a person's mind when evaluating a specific topic or decision, often leading to biased outcomes.

Priming

the process in which exposure to a stimulus influences response to a subsequent stimulus, often without conscious awareness.

Nudge theory

is a concept in behavioral economics that proposes positive reinforcement and indirect suggestions to influence behavior and decision-making. It suggests small changes in the environment can lead to significant shifts in behavior.

Gambler’s fallacy NIT

The belief that past random events can influence the outcome of future random events, particularly in games of chance, leading individuals to make irrational betting decisions.

Sunk cost fallacy NIT

The tendency to continue an endeavor once an investment in money, effort, or time has been made, even when the costs outweigh the benefits.

9-4: What factors exaggerate our fears of unlikely events?

Factors such as availability heuristics, media coverage, and personal experiences can amplify our fear of unlikely but dramatic events, leading to irrational risk assessments.

9-5:How are our decisions and judgements affected by overconfidence, belief perseverance, and framing?

Our decisions and judgments can be influenced by overconfidence in our abilities, leading us to underestimate risks. Belief perseverance causes us to cling to our initial beliefs despite contrary evidence, while framing effects alter our perceptions and choices based on how information is presented.

Overconfidence

Overconfidence is a cognitive bias where an individual has an unjustifiably high level of confidence in their own abilities or predictions, often leading to misjudgment. This can result in underestimating risks or overlooking potential problems.

Belief perseverance

Belief perseverance is the tendency to hold on to one’s initial beliefs even when presented with contradictory evidence, often leading to distorted reasoning.

Framing

Framing refers to the way information is presented, which can significantly influence decisions and judgments. Different presentations of the same facts can lead to different choices or evaluations.

9-6: What are the structural components of a language?

The structural components of a language include phonetics, phonology, morphology, syntax, semantics, and pragmatics. These elements work together to form the systems of communication within a language.

Language NIT

A system of communication using sounds, symbols, and gestures that follows specific rules to convey meaning.

Phonemes

the smallest units of sound in a language that can distinguish meaning, such as the sounds of letters or syllables.

Morphemes

The smallest units of meaning in a language that can be combined to form words.

Grammar

The set of rules that govern the structure of sentences in a language, including syntax and punctuation.

Semantics NIT

the study of meaning in language, including the meanings of words, phrases, and sentences.

Syntax NIT

the set of rules that govern the structure of sentences, particularly the order and arrangement of words.

9-7: What is creativity, and what fosters it?

Creativity is the ability to generate novel and meaningful ideas or solutions. It is fostered by factors such as a supportive environment, diverse experiences, encouragement of risk-taking, and the ability to think divergently.

Creativity

the ability to produce original and valuable ideas, often fostered by an open-minded environment, collaboration, and exposure to diverse experiences.

convergent thinking

a thought process that focuses on finding the single best solution to a problem. It often involves applying learned knowledge and skills to reach a conclusion.

divergent thinking

a thought process that generates multiple, unique solutions to a problem. It encourages creativity by exploring various possibilities rather than focusing on a single answer.

9-8: What do we know about thinking in other species?

Research shows that many non-human species exhibit problem-solving skills, use tools, and display complex social behaviors, indicating forms of cognition similar to those in humans.

9-9: What are the structural components of language?

The structural components of language include phonemes, morphemes, syntax, semantics, and pragmatics, which together allow for the construction and interpretation of meaningful communication.

phonemes

the smallest units of sound that contribute to meaning in a language. They combine to form words and are fundamental to phonetics.

morphemes

the smallest units of meaning in a language, which can be words or parts of words, such as prefixes and suffixes.

grammar

the rules and structures that govern the composition of sentences in a language, including syntax and morphology.

9-10: How do we acquire language, and what is universal grammar?

Language acquisition develops through an interaction of an innate biological capacity and environmental exposure during early childhood. Linguist Noam Chomsky proposed Universal Grammar (UG), arguing that all human languages share a basic underlying structure and that humans are biologically pre-equipped with an inherent ability to learn grammar rules, rather than acquiring language solely through behavioral imitation and reinforcement.This theory suggests that children are born with the ability to understand the fundamental principles of grammar common to all languages, facilitating the learning process.

Universal grammar (UG)

is the theory that suggests all human languages are derived from a common structural basis, enabling children to learn language naturally.

9-11: What are the milestones in language development, and when is the critical period for language development?

4 months → babbling

around 1 year →one-word stage

around 18 months to 2 years → two-word stage

the critical period for language development is generally regarded as the time from birth until around age 7, where children are particularly receptive to acquiring language skills. if they have zero language exposure by age of 7 they are likely to never develop that skill.

Receptive language NIT

is the ability to understand and process language, including recognizing words, phrases, and sentences, even before one can express language verbally. this is in babies around 4-10 months

Productive language NIT

is the ability to produce and express language verbally, including forming words, phrases, and sentences. This typically develops after receptive language, around 10-12 months of age.

Babbling

is the stage of language development that begins around 4 months of age, characterized by the production of nonsensical consonant-vowel combinations, which serves as a precursor to later speech.

One-word stage

refers to the early stage of language development, typically occurring between 12-18 months, where a child begins to use single words to convey meaning and express needs.

Two-word stage

refers to the stage of language development occurring around 18-24 months, where a child starts to combine two words to create simple sentences, conveying more complex ideas or requests.

Telegraphic speech

is a form of speech typically used by children around age 2, characterized by the use of two or more words in a concise manner, often omitting less critical words to convey a clear message.

Critical period

the optimal time frame in which a child must be exposed to language in order to develop normal language skills. This period typically occurs in early childhood. If a child is not exposed to language during this critical period, they may struggle to acquire language skills later in life. It is believed that the critical period for language acquisition is roughly between birth and age 7, highlighting the importance of early exposure to language.

Cooing NIT

is an early stage of language development, typically occurring between 6 to 8 weeks of age, where infants produce soft, vowel-like sounds as a form of vocal expression. This is an important precursor to later stages of speech and language.

Overgeneralization

is a common language error made by children where they apply grammatical rules too broadly, such as using "goed" instead of "went" or "mouses" instead of "mice." This reflects their developing understanding of language rules.

9-12: What brain areas are involved in language processing and speech?

The brain areas involved in language processing and speech include Broca's area which is the left side of the frontal cortex, is responsible for speech production, and Wernicke's area which is on the left side of the temporal lobe, is crucial for language comprehension. Both areas are located in the left hemisphere of the brain and work together to facilitate effective communication.

Aphasia

is a language disorder that affects a person's ability to communicate. It can impair speech production, comprehension, and the ability to read or write, often resulting from brain damage.

Broca’s area

A region in the left frontal lobe of the brain that is primarily responsible for the production of speech and the formation of language.

Wernicke’s area

A region in the left temporal lobe of the brain that is primarily responsible for language comprehension and the understanding of spoken and written language.

9-13: What do we know about other species’ capacity for language?

Some non-human species, such as primates and birds, exhibit forms of communication that share characteristics with human language, including the use of symbols, sounds, and gestures. However, their ability to use language is generally more limited than that of humans, often lacking the complexity and grammatical structure.

9-14: What is the relationship between language and thinking, and what is the value of thinking in images?

The relationship between language and thinking is often described by the hypothesis that language shapes thought processes, influencing how individuals perceive and conceptualize the world. Thinking in images provides a valuable mental representation that can aid in problem-solving, creativity, and memory.

Linguistic determinism

The hypothesis that language determines the way individuals think and perceive the world, suggesting that people who speak different languages may experience reality differently.

Linguistic relativism NIT

The principle that the structure of a language influences its speakers' worldview and cognition, implying that speakers of different languages may think and understand the world in unique ways.

Chapter 10: Intelligence

The study of mental abilities, including the capacity to learn, reason, solve problems, and adapt to new situations. Intelligence is often measured through standardized tests and can encompass various types, such as analytical, creative, and practical intelligence.

10-1: How is intelligence defined, and what are the arguments for g?

Intelligence is defined as the capacity to learn from experience, reason, solve problems, and adapt to new situations. The theory of 'g' or general intelligence suggests that there is a single underlying factor that contributes to performance across various cognitive tasks.

Factor analysis

A statistical method used to identify the underlying relationships between variables, often employed in intelligence research to determine the existence of general intelligence (g) by grouping correlated cognitive abilities.

10-2: How do Gardner’s and Sternberg’s theories of multiple intelligences differ, and what criticisms have they faced?

Gardner’s theory proposes multiple distinct intelligences including linguistic, logical-mathematical, musical, and others, while Sternberg’s triarchic theory emphasizes analytical, creative, and practical intelligence. Criticisms of Gardner’s theory include a lack of empirical support for distinct intelligences, whereas Sternberg’s theory has been challenged for its vagueness and ambiguity in defining its components.

Savant syndrome

A condition in which a person with significant mental disabilities demonstrates exceptional skills in a specific area, such as music, art, calculation, or memory, often accompanied by a lack of general cognitive functioning.

Multiple intelligences

A condition where a person with significant mental disabilities demonstrates exceptional abilities in a specific area, such as music or mathematics, highlighting the theory of multiple intelligences.

Sternberg’s triarchic theory of intelligence

Sternberg’s triarchic theory of intelligence posits three types of intelligence: analytical, creative, and practical, each contributing to overall cognitive performance and problem-solving ability.

Analytical intelligence

refers to the ability to analyze, evaluate, and apply information effectively, typically measured by traditional IQ tests. It is one of the three components of Sternberg's triarchic theory, along with creative and practical intelligence.
