Cognition: Thinking, Intelligence, and Language - Study Notes

Psychology Chapter 7: Cognition - Thinking, Intelligence, and Language

Cognition

  • Cognition: Refers to mental activity involved in processing information, including organizing, understanding, and communicating information. Involves both words and images.

7.1 Attention

  • Attention: A limited resource comprising processes that control the flow of information through the nervous system.

    • Selective Attention: The process of focusing on specific stimuli while ignoring others for dedicated processing.

    • Sustained Attention: The ability to remain alert during prolonged periods of focus.

7.2 Mental Imagery

  • Mental Images: Mental representations standing for objects or events. They possess a picture-like quality.

    • Differ in cerebral processing compared to actual perception. Visual stimuli are perceived faster (bottom-up processing) than generated mental images (top-down processing).

Study Example: Kosslyn’s Fictional Island (1978)

  • Participants had to indicate when they imagined moving between locations on an island. Results demonstrated that participants took longer to respond as distances increased between imagined locations, indicating an analogy to physical distance.

7.3 Concepts and Prototypes

  • Concepts: Ideas representing different categories of objects, events, or activities.

    • Formal Concepts: Defined by specific rules or features.

    • Natural Concepts: Formed through real-world experiences; e.g., a platypus is a “fuzzy” natural concept due to shared traits with both mammals and birds.

  • Prototype: The best example that closely embodies the defining characteristics of a concept. Prototypes vary based on an individual's exposure to the category.

    • Schemas: Mental frameworks for organizing knowledge about objects, people, and events.

    • Scripts: A type of schema defining a sequence of expected activities (e.g., steps in a restaurant).

7.4 Problem-Solving and Decision-Making

  • Problem-Solving: Occurs when a definitive goal is to be achieved through thought and behavior.

  • Decision-Making: Involves evaluating and choosing between alternatives.

    • Trial and Error: A method where multiple solutions are attempted until one succeeds.

    • Algorithms: Step-by-step procedures guaranteeing a solution if one exists (e.g., formulas).

    • Heuristics: Educated guesses enabling faster problem-solving by narrowing down options.

    • Types of Heuristics:

    • Representative Heuristic: Judging likelihood based on similarity to prototypes.

    • Availability Heuristic: Relying on immediate examples that come to mind.

    • Working Backward: Starting with the desired goal and working in reverse to find the solution.

    • Subgoals: Breaking a problem into smaller, manageable parts.

  • Insight: Sudden realization of a problem's solution (often characterized as an "Aha!" moment).

7.5 Barriers to Problem-Solving and Decision-Making

  • Functional Fixedness: Inability to see objects as having uses other than their typical function.

  • Mental Set: Persistent use of previously successful problem-solving strategies, potentially limiting effectiveness against new problems.

  • Confirmation Bias: The tendency to seek evidence supporting existing beliefs while ignoring contradictory evidence.

7.6 Creativity

  • Creativity: The process of solving problems innovatively by combining ideas in novel ways.

    • Convergent Thinking: Solving issues with a single correct solution.

    • Divergent Thinking: Generating multiple possibilities from a single point, showcasing creativity.

Table: Strategies to Stimulate Divergent Thinking

  • Brainstorming: Idea generation without immediate criticism.

  • Keeping a Journal: Recording ideas as they occur.

  • Freewriting: Writing everything related to a topic without self-editing.

  • Mind Mapping: Visualizing concepts and their connections.

7.7 Theories of Intelligence

  • Intelligence: The capacity to learn from experiences, acquire knowledge, and effectively adapt to new situations.

  • Spearman's G Factor:

    • g Factor: General intelligence involving reasoning and problem-solving.

    • s Factor: Specific intelligence in focused areas.

  • Cattell-Horn-Carroll (CHC) Theory:

    • Distinguishes between Crystallized Intelligence (knowledge and skills) and Fluid Intelligence (problem-solving and adaptability).

Additional Theories

  • Parieto-Frontal Integration Theory: Emphasizes the role of frontal and parietal lobes.

  • Gardner’s Multiple Intelligences: Proposes various independent intelligences (e.g., linguistic, logical, spatial, etc.).

  • Sternberg’s Triarchic Theory: Differentiates between analytical, creative, and practical intelligence.

  • Emotional Intelligence: Includes self-awareness and understanding emotions in oneself and others.

7.8 Measuring Intelligence

  • Binet’s Mental Ability Test: Designed to differentiate learners' abilities by age.

  • Stanford-Binet Test: Introduced the IQ scale: IQ=racMACAimes100IQ = rac{MA}{CA} imes 100.

  • Wechsler Tests: Series of tests measuring different age group intelligence, providing verbal and non-verbal assessments.

Example Items from Wechsler Adult Intelligence Scale (WAIS-IV)

  • Verbal Comprehension: Similarities and vocabulary assessments.

  • Perceptual Reasoning: Block design and matrix reasoning tasks.

  • Working Memory: Digit span and simple arithmetic problems.

7.9 Evaluating Test Quality

  • Reliability: Consistency of test scores over repeated administrations.

  • Validity: Degree to which the test measures what it claims to.

  • Standardization: Ensuring test administration consistency and comparison to relevant norms (most intelligence tests follow a normal curve).

7.10 Individual Differences in Intelligence

  • Intellectual Disability: Characterized by an IQ below 70, with significant deficits in adaptive behaviors starting in childhood.

  • Giftedness: Refers to individuals scoring above 130 IQ, who may not necessarily guarantee success but often thrive in supportive environments.

7.11 Nature vs. Nurture in Intelligence Development

  • Heredity Influence: Studies suggest stronger genetic correlations in IQ among closer relatives.

  • Environment Impact: The Flynn Effect indicates a rise in IQ scores over time in modernized countries.

7.12–7.15 Language

  • Language: A symbol system for forming meaningful communication.

    • Elements of Language:

    • Phonemes: Basic sounds.

    • Morphemes: Smallest meaning units.

    • Syntax: Structure rules governing sentence formation.

    • Semantics: Meaning rules for words and sentences.

    • Pragmatics: Practical usage in social contexts.

Stages of Language Development

  1. Cooing: 2 months - vowel-like sounds.

  2. Babbling: 6 months - consonant sounds add to cooing.

  3. One-word Speech: 1 year - single words representing entire meanings.

  4. Telegraphic Speech: 1.5 years - simple phrases using critical words.

  5. Whole Sentences: Preschool period - nearly fluent speech but limited vocabulary.

7.14 Language and Thought Relationship

  • Linguistic Relativity Hypothesis: Suggests language influences thought.

  • Cognitive Universalism: Proposes universal concepts impacting language development.

7.15 Nonhuman Animal Communication Studies

  • Evidence indicates animals can communicate and may learn basics of language, but mastery of syntax remains debated.

7.16 Recognizing Cognitive Biases

  • Acknowledgment of personal cognitive biases can help limit their impacts on decision-making.

  • Awareness of cognitive biases can lead to improved critical thinking and decisions in real-life scenarios.
