Chapter 7 Cognition,Language & Intelligence

Cognition

  • Definition:

    • Cognition is defined by psychologists as the brain activity involved in the mental manipulation of information. This includes data types such as:

    • Words

    • Visual images

    • Sounds

    • Other forms of data

  • Meaning of Cognition and Thinking:

    • Cognition and thinking are synonymous; cognitive processes allow the transformation of information into new and different forms, facilitating the ability to:

    • Answer questions

    • Make decisions

    • Solve problems

    • Make plans

Forms of Cognition

  • Examples of Cognitive Processes:

    • Catching a Ball:

    • Requires tracking the object and positioning oneself for an effective catch.

    • The parietal lobe processes spatial information to determine the ball's location relative to the body.

    • Playing Chess:

    • Involves anticipating an opponent’s moves and planning strategies accordingly.

    • Statistics in Chess:

      • 20 possible first moves

      • 400 possible positions after one pair of moves

      • 288 billion possible positions after four moves

Cognitive Psychology

  • Definition:

    • A branch of psychology that focuses on mental processes:

    • Thinking

    • Language

    • Memory

    • Problem-solving

    • Knowing

    • Reasoning

    • Judging

    • Decision making

Mental Images

  • Definition:

    • Mental images are representations in the mind of objects or events.

  • Sensory Modalities:

    • Mental images are not limited to visual aspects; they can include auditory elements, such as hearing songs in one’s mind.

    • Research (Gardini et al., 2009) suggests that mental imagery may enhance skill performance (e.g., visualization in sports).

  • Aphantasia:

    • Definition: The inability to create mental images.

    • Prevalence: Approximately 1% of the population experiences complete Aphantasia, and it is more frequent in individuals on the Autism Spectrum.

Concepts

  • Definition of Concepts:

    • Mental groupings of similar objects, events, or people.

    • Example: Categories like “Fruit” or “Meat” serve to organize complex phenomena into manageable cognitive categories.

  • Function of Concepts:

    • Concepts aid in the classification of new objects and influence behavior in practical situations (e.g., deciding which animals are suitable to pet).

Prototypes

  • Definition:

    • Prototypes are highly representative examples of concepts, shaped by personal mental images.

  • Cultural Influence on Prototypes:

    • Cultures can significantly affect what prototypes are viewed as typical.

    • Example group activity: Identifying prototypes by culture for items such as eating utensils, church clothing, and casual wear.

Heuristics

  • Definition:

    • Heuristics are cognitive strategies or shortcuts that may not always lead to correct conclusions.

  • Types of Heuristics:

    • Availability Heuristic:

    • Judging likelihood based on what is easily recalled (e.g., the popularity of political policies due to media coverage).

    • Anchoring Heuristic:

    • Making estimates based on an initial anchor (e.g., a sale price that seems attractive based on its original price).

    • Familiarity Heuristic:

    • Choosing options based on prior familiarity, regardless of available alternatives (e.g., selecting a familiar restaurant).

    • Present Bias:

    • The tendency to favor immediate rewards over greater future benefits (e.g., preferring $150 now over $180 in a week).

Solving Problems

  • Cognitive Psychology and Problem Solving:

    • Cognitive psychologists analyze the methodologies individuals use to solve puzzles, reflecting on real-life problem-solving processes.

  • Steps in Problem Solving:

    1. Preparing

    2. Producing solutions

    3. Evaluating solutions

  • Two Types of Problems:

    • Well-defined Problems:

    • Problems with clear definitions and known solutions (e.g., solving a mathematical equation).

    • Ill-defined Problems:

    • Problems lacking clarity and requiring innovative solutions (e.g., enhancing staff morale).

Preparation in Problem Solving

  • Initial Stage:

    • Develop a personal cognitive representation of the problem; requires understanding the initial state relative to a desired goal.

Production in Problem Solving

  • Examining Solutions:

    • Solutions can come from stored knowledge or must be created anew.

  • Trial and Error Method:

    • While this strategy is basic, it may not always lead to a research-based solution.

Means-End Analysis

  • Process Description:

    • Involves identifying:

    1. The goal

    2. The current state

    3. The gap between them

    4. Generating sub-goals to bridge that gap

    5. Applying actions towards those sub-goals

    6. Repeat until the goal is met

  • Means-End Analysis Example: Buying a Laptop

    • Example Steps:

    • Goal: Own a new laptop.

    • Current State: No laptop at home.

    • Action Steps to meet the Goal: Research, travel to a store, and purchase a laptop.

Judgement Stage in Problem Solving

  • Outcome Evaluation:

    • If the solution is straightforward, success is easily identified; in less clear circumstances, evaluating solutions demands more effort.

Cognitive Biases in Problem Solving

  • Confirmation Bias:

    • The inclination to focus on evidence supporting an initial hypothesis while disregarding contradictory information.

    • Example: Retrospective analysis of the 2003 US invasion of Iraq.

  • Functional Fixedness:

    • The tendency to resonate with an object’s typical application (e.g., a book as a reading material rather than as a doorstop).

  • Mental Set:

    • Solving problems in a manner based on past experiences can inhibit the exploration of alternative solutions.

Creativity in Problem Solving

  • Definition:

    • Creativity entails generating novel ideas or approaches to solving problems.

  • Types of Thinking:

    • Divergent Thinking:

    • Produces multiple appropriate responses.

    • Convergent Thinking:

    • Leads to a single correct answer based on logic and knowledge.

Types of Problems in Problem Solving

  • Arrangement Problems:

    • Require rearranging elements to meet specific criteria (e.g., puzzles).

  • Inducing Structure Problems:

    • Demand identifying relationships among presented elements (e.g., predicting the next number in a series).

  • Transformation Problems:

    • Involve transitioning from an initial state to a goal state (e.g., the Towers of Hanoi puzzle).

Language

  • Definition:

    • Language involves communication via symbols ordered by systematic rules and is integral to cognitive abilities.

  • Developmental Stages:

    • Babbling stage (3 months to 1 year): Early speech sounds reflect language exposure.

    • One year: Children produce single words mainly beginning with consonant sounds.

    • Age 2: Children exhibit telegraphic speech, using essential words: e.g., "I show book" instead of "I showed you the book."

    • Age 3: Plural and tense rules begin to be applied, leading to overgeneralization.

    • Age 5: Basic language rules are acquired, with vocabulary and comprehension developing later.

Theories of Language Development

  • Interactionist Approach:

    • Combines genetic predispositions with environmental influences for language acquisition.

  • Nativist Approach:

    • Proposes humans are hard-wired for language learning at specific ages.

Components of Language

  • Grammar:

    • Rules governing expression of thoughts.

  • Phonology:

    • Study of phonemes, the smallest speech units.

  • Syntax:

    • Structures for combining words into sentences.

  • Semantics:

    • Meaning of words and sentences.

Intelligence

  • Definition:

    • Intelligence is understood as the capacity to understand the world, think rationally, and efficiently utilize resources when faced with issues.

  • Types of Intelligence:

    • Fluid Intelligence:

    • Skill to think logically and abstractly; used for personal or social problem-solving.

    • Crystallized Intelligence:

    • Knowledge and skills acquired through experience and education, residing in long-term memory.

Emotional Intelligence

  • Definition:

    • A set of skills enabling accurate emotional assessment, evaluation, expression, and regulation (Mayer, Salovey, & Caruso, 2008).

  • Examples:

    • Self-Awareness and Management:

    • Regulating emotions by staying calm under pressure.

    • Acknowledgement of Feelings:

    • Recognizing colleagues' emotions during feedback exchanges; practicing active listening.

Multiple Intelligences Theory

  • Howard Gardner’s theory:

    • Proposes at least eight independent forms of intelligence:

    1. Musical

    2. Bodily-kinesthetic

    3. Logical-mathematical

    4. Linguistic

    5. Spatial

    6. Interpersonal

    7. Intrapersonal

    8. Naturalist

  • Each intelligence type correlates with individual neural systems.

  • Contrast with General Intelligence Theory:

    • Charles Spearman's theory suggests a singular, overarching intelligence factor referred to as G.

Intelligence Assessments

  • Alfred Binet & Theodore Simon:

    • Developed the concept of mental age, reflecting intelligence levels relative to age-group performance.

    • Established the Stanford-Binet Intelligence Scale.

  • William Stern:

    • Introduced Intelligence Quotient (IQ) as a measurement of intelligence based on test performance, initially calculated as the ratio of mental age to chronological age.

  • WAIS-IV and WISC-V:

    • Currently dominant IQ assessments, with WAIS-IV normed for an average IQ of 100, demonstrating a bell-shaped distribution across scores.

  • Characteristics of Good Intelligence Tests:

    • Reliability: Stability of scores over time.

    • Validity: Accuracy of what is being measured.

    • Predictive Validity: Ability to forecast future behavior or performance.

    • Culture-fair tests: Designed to eradicate cultural biases.

  • Mainstreaming Practice:

    • The integration of children with special needs into general classroom settings.

The Importance of IQ

  • Robert Sternberg’s Perspective:

    • Proposed the theory of Successful Intelligence, which encompasses the adaptation, shaping, and selection of environments to achieve success.

  • Three Components of Successful Intelligence:

    • Analytical

    • Creative

    • Practical
