What is Cognition?

Learning Objectives

  • Describe cognition.

  • Distinguish between concepts and prototypes.

  • Explain natural and artificial concepts.

  • Describe how schemata are organized and constructed.

Definition of Cognition

  • Cognition involves the processes of perception, knowledge, problem solving, judgment, language, and memory.

  • It refers to thinking and encompasses both conscious and unconscious activities within the brain - constantly active in organizing, planning, and remembering.

  • Example of cognition:

    • Planning daily errands indicates cognitive processing at work.

Cognitive Psychology

  • Dedication to understanding how people think, including:

    • Relationships between thought, emotion, creativity, language, and problem-solving.

    • Measurement and types of intelligence.

    • Organizational strategies for thoughts and information from environments.

Concepts and Prototypes

  • The nervous system processes vast amounts of information from our senses, leading to the formulation of thoughts.

  • These concepts help organize our understanding of experiences, categorized into:

    • Concepts: Categories of information (detailed linguistic information, ideas, memories).

    • Generated by observing, categorizing, and combining information.

    • Examples include historical knowledge and abstract concepts like justice.

    • Relationships among concepts aid in information retention and understanding.

  • Prototypes: Best exemplars of concepts, e.g., a person’s first experience with a dog shaping their prototype of what a dog is.

Natural vs. Artificial Concepts

  • Natural Concepts: Formed through experience (direct or indirect). Example: A person in the Caribbean may only know about snow through pictures and movies, while someone in Northern Canada has direct experience with it.

  • Artificial Concepts: Defined by specific characteristics, like geometric shapes or mathematical principles, allowing structured understanding easily communicated.

Schemata

  • Schemata: Mental constructs of related concepts that allow efficient information organization.

    • Activation leads to assumptions about people or objects observed.

    • Types of schemata include:

    • Role Schema: Assumptions about behaviors of individuals in certain roles (e.g., firefighters).

    • Event Schema: Routines of behavior in common situations (e.g., riding in elevators).

Language

Learning Objectives

  • Define language.

  • Understand components and development of language.

  • Explore the relationship between language and cognition.

Definition and Components of Language

  • Language: A system for communication using words and grammar. Components include:

    • Lexicon: Vocabulary of a language.

    • Grammar: Rules that convey meaning by organizing the lexicon.

    • Phonemes & Morphemes: Basic sound units and smallest meaning-bearing units, respectively.

    • Semantics & Syntax: Processes of deriving meaning from morphemes and organization of words into sentences.

Language Acquisition

  • Children learn language through:

    • Observation and social interaction (Skinner's theories).

    • Development of generativity (speaking new sentences).

    • Evidence from studies shows that language can develop naturally beyond mere imitation.

Theories of Language Acquisition

  • Nativist Perspective (Chomsky): Humans are prewired for language acquisition through a universal grammar.

  • Critique of nativist perspective: Some languages lack features assumed to be universal.

Language Development Stages

Detailed timeline from birth to age five in learning language, highlighting key milestones in stages:

  • Birth: Crying

  • 0-6 months: Cooing

  • 5-6 months: Babbling

  • 12-18 months: One-word utterances

  • 18-24 months: Two-word utterances

  • 2-3 years: Simple sentences

  • 3-5 years: More complex sentences.

Problem Solving

Learning Objectives

  • Describe problem-solving strategies.

  • Define algorithm and heuristic.

  • Explain common roadblocks in problem-solving.

Problem Solving Defined

  • Engaging with the identifiable problem and applying strategies to resolve it.

  • Problem-Solving Strategy: A plan to find an action to solve a problem. Examples include:

    • Trial and Error: Continuing to attempt various solutions until resolving the issue.

    • Algorithm: Exact instructions for a specific outcome (recipe-like).

    • Heuristic: General approach to problem-solving (rule of thumb).

Common Roadblocks in Problem Solving

  • Mental Set: Persisting in approaches that worked in the past, even when inappropriate.

  • Functional Fixedness: Inability to see an object being used beyond its intended purpose.

Decision-Making Biases

  • Biases: Distortions that affect the reasoning process; include:

    • Confirmation Bias: Focus on information reinforcing existing beliefs.

    • Hindsight Bias: Perception that outcomes were predictable after the fact.

    • Anchoring Bias: Fixation on one piece of information affecting decisions.

    • Availability Heuristic: Relying on immediate examples when making judgments.

What Are Intelligence and Creativity?

Learning Objectives

  • Define intelligence.

  • Explain theories of intelligence.

  • Describe emotional intelligence and its impact.

Intelligence Overview

  • Intelligence definitions have evolved, classic views include that of Charles Spearman with the general factor “g” and Raymond Cattell's distinction between fluid and crystallized intelligence.

  • Sternberg’s triarchic theory categories intelligence into practical, creative, and analytical dimensions.

  • Emotional Intelligence: Recognizes and manages one’s own emotions while empathizing with others’ feelings.

Theories of Intelligence

  • Multiple Intelligences (Gardner): Encompasses eight distinct intelligences.

  • Cattell-Horn-Carroll (CHC) Theory: Hierarchical arrangement of cognitive abilities, leading to various measurement categories.

Measures of Intelligence

Learning Objectives

  • Discuss the development of intelligence tests and their purposes.

Intelligence Testing History

  • Development of IQ measurements began with Binet and Terman’s expansion into the Stanford-Binet test.

  • Wechsler introduced new scales (WAIS, WISC) emphasizing diverse cognitive abilities.

Bell Curve in Intelligence Assessment

  • Intelligence scores follow a bell curve distribution with average scores clustering around 100.

  • Discusses IQ score importance in diagnostic contexts, like intellectual disability determinations.

The Source of Intelligence

Learning Objectives

  • Describe the relationship of genetics and environment in intelligence.

  • Explore how socioeconomic and cultural factors influence IQ and learning.

Intelligence Influencers

  • Genetic influences suggest a significant heritability component.

  • Environmental aspects are crucial: enriching experiences stimulate cognitive growth.

  • Socioeconomic factors and stress assessment were highlighted in educational contexts, emphasizing negative implications for individuals living in poverty.

Ethics and Implications

  • Discussed role of IQ in eugenics, biases in testing, and implications for social policy and education.

Conclusion

  • Understanding cognition, intelligence, language, and personality reveals a complex array of factors influencing human behaviour and their impacts across different contexts.
