Study Notes

Problem-Solving Strategies

  • Trial and Error: A method of problem-solving that involves trying multiple solutions and discarding those that fail.
  • Algorithms: Step-by-step procedures that guarantee a correct solution, such as mathematical formulas.
  • Heuristics: General rules of thumb that simplify decision-making and problem-solving by reducing options, like using a search function in Help documentation.

Cognitive Processes in Problem Solving

  • Insight: A sudden understanding of how to solve a problem, often linking it with previously encountered issues.
  • Functional Fixedness: The limitation to see an object only for its intended use, hindering creative problem-solving.
  • Mental Set: Relying on prior successful solutions may restrict the ability to see new alternatives.

Decision-Making Models

  • Single-feature Model: A decision-making strategy focusing on one significant attribute, effective for minor decisions.
  • Additive Model: Involves evaluating multiple important features of choices by scoring them according to personal significance.
  • Elimination by Aspects Model: Considers each option against essential features sequentially, discarding alternatives that don't meet specific criteria.

Cognitive Biases and Heuristics

  • Availability Heuristic: Estimation of event likelihood based on how easily instances come to mind, often distorted by vivid memories.
  • Representativeness Heuristic: Estimation of event likelihood compared to prototypes, affecting risk assessment in decision-making.

Language and Thought

  • Linguistic Relativity Hypothesis: Suggests language shapes thought, leading to different perceptions, such as color recognition across cultures.
  • Phonemes and Morphemes: Phonemes are distinct sound units in language that differentiate words, while morphemes are the smallest grammatical units that may or may not stand alone.

Intelligence Theories

  • Alfred Binet: Developed tests for identifying students needing extra help, introducing the concept of mental age.
  • Lewis Terman: Revised Binet’s tests into the Stanford-Binet Intelligence Scale and popularized the IQ score.
  • Charles Spearman: Proposed the g factor theory, suggesting a single underlying intelligence influences various cognitive abilities.
  • Howard Gardner: Introduced the theory of multiple intelligences, suggesting diverse cognitive skills valued differently across cultures.
  • Robert Sternberg: Proposed a broader understanding of intelligence, emphasizing adaptability to social and cultural contexts.

Stereotypes and Performance

  • Claude Steele: Coined the term stereotype threat, indicating negative expectations can impair performance relative to actual ability.

Linguistics Components

  • Semantics: Study of meaning in language, encompassing various branches that analyze word relations and meanings.
  • Syntax: Rules governing sentence structure and word order, essential for constructing coherent statements.
  • Generativity of Language: The ability to generate and comprehend novel sentences that have never been uttered before.
  • Displacement: The capacity of language to discuss concepts not present in immediate time or space.
