Cognition

Cognition refers to the mental processes involved in acquiring, processing, storing, and using information.

Types of Thinking
  • Autistic thinking – A type of self-centered thought process often detached from reality, where a person focuses on personal fantasies, dreams, or private logic rather than external reality.

  • Directed thinking – Logical, goal-oriented thinking used for problem-solving, reasoning, and decision-making.

  • Reasoning – The process of drawing conclusions based on information and logical thought.

  • Deductive reasoning – A logical process where conclusions follow from general principles (e.g., "All men are mortal. Socrates is a man. Therefore, Socrates is mortal.").

  • Inductive reasoning – The process of drawing general conclusions from specific observations (e.g., "Every swan I’ve seen is white, so all swans must be white.").

  • Metacognition – Thinking about thinking; the ability to analyze and control one's cognitive processes.


Concepts and Prototypes

  • Concept – A mental grouping of similar objects, ideas, or people. There are three main types:

    1. Superordinate concepts – Broad categories (e.g., "animal").

    2. Basic-level concepts – More specific categories (e.g., "dog").

    3. Subordinate concepts – Even more detailed (e.g., "Golden Retriever").

  • Typicality – The degree to which an object or idea fits the prototype of a category.

  • Prototype – The best example of a concept (e.g., a robin as a prototype of a bird).

  • Images – Mental representations of objects or events.


Problem-Solving Strategies

  • Algorithms – A step-by-step, logical procedure that guarantees a solution (e.g., a math formula).

  • Heuristic – A mental shortcut or rule of thumb used to make quick decisions.

    • Representative heuristic – Judging a situation based on how similar it is to a prototype (e.g., assuming someone who loves books is a librarian).

    • Availability heuristic – Judging likelihood based on how easily examples come to mind (e.g., fearing plane crashes more than car accidents because of media coverage).

  • Insight – A sudden realization of a problem’s solution, often occurring unexpectedly.

  • Convergent thinking – Narrowing down multiple options to find the best single solution.

  • Divergent thinking – Generating multiple, creative solutions to a problem.


Impediments to Thinking

  • Confirmation bias – The tendency to seek out information that supports our beliefs while ignoring contradictory evidence.

  • Implicit assumptions – Unconscious beliefs or assumptions that influence thinking.

  • Fixation – The inability to see a problem from a new perspective.

    • Mental set (also called rigidity) – The tendency to approach problems in a habitual way, even if it's not effective.

    • Functional fixedness – The inability to see new uses for an object beyond its usual function (e.g., seeing a screwdriver only as a tool for screws, not as a potential weight for a pendulum).


Other Cognitive Biases and Thought Patterns

  • Overconfidence – The tendency to overestimate the accuracy of our knowledge and judgments.

    • Pros: Can improve motivation, persistence, and decision-making.

    • Cons: Can lead to errors, risk-taking, and poor decisions.

  • Framing – The way information is presented influences decision-making (e.g., "90% survival rate" sounds better than "10% death rate").

  • Belief bias – The tendency to accept conclusions that align with our beliefs while rejecting logical ones that contradict them.

  • Belief perseverance – Holding on to beliefs even after they have been proven wrong.


Artificial Intelligence (AI) and Neural Networks

  • Artificial intelligence (AI) – The creation of machines that can perform tasks requiring human-like intelligence, such as learning, problem-solving, and decision-making.

  • Computer neural networks – AI systems modeled after the human brain that learn from experience and recognize patterns.


Language

Language is a system of symbols and rules used for communication.

Key Components of Language

  • The five key factors of language:

    1. Phonemes – The smallest units of sound in a language (e.g., "b" in "bat").

    2. Morphemes – The smallest units of meaning (e.g., "un-" in "undo").

    3. Grammar – The system of rules that enables communication.

      • Semantics – The meaning of words and sentences.

      • Syntax – The arrangement of words into grammatically correct sentences.

      • Prosody – The rhythm, stress, and intonation of speech.

  • The four criteria for a true language:

    1. Symbolism – Words and symbols represent objects, actions, and ideas.

    2. Syntax – Rules for combining words into meaningful sentences.

    3. Generativity – The ability to create an infinite number of sentences.

    4. Displacement – The ability to communicate about things not immediately present.


Language Acquisition

The process by which humans learn language.

Stages of Language Acquisition

  1. Cooing/Babbling (0-6 months) – Infants produce sounds that are not yet words.

  2. One-word stage (12-18 months) – Children use single words to represent entire thoughts.

    • Holophrase – A single word representing a complete idea (e.g., "milk" meaning "I want milk").

    • Overextension – Using one word for too many things (e.g., calling all animals "dog").

  3. Two-word stage (18-24 months) – Children start combining words into simple phrases.

    • Overgeneralization – Applying grammar rules too broadly (e.g., "goed" instead of "went").

  4. Beyond two-word stage (2+ years) – Rapid vocabulary growth and mastery of complex sentences.


Theories of Language Acquisition

  • Behaviorist view (B.F. Skinner) – Language is learned through imitation, reinforcement, and conditioning.

  • Cognitive view (Noam Chomsky) – Humans are biologically wired to learn language through an innate Language Acquisition Device (LAD) that enables learning grammar naturally.


Thinking and Language

  • Benjamin Whorf’s linguistic determinism hypothesis – Language shapes the way we think (e.g., people who speak different languages perceive the world differently).

  • Edward Sapir and Benjamin Whorf – Expanded on linguistic determinism, arguing that language influences but does not entirely determine thought.
