Study Notes
Measuring Individual Differences
- Many characteristics (e.g., intelligence, personality) are indirectly observed, requiring specific measurement approaches.
- Measuring these traits involves a multi-stage process: first defining the trait, then developing operational methods.
Intelligence
- Intelligence is a broad concept encompassing purposeful action, rational thinking, and effective environmental interaction (Wechsler, 1958).
- General intelligence (G) is a broad factor underlying various cognitive tasks.
- Specific abilities, in addition to general intelligence, contribute to cognitive performance, dependent on the task.
- Fluid and crystallized intelligence (Cattell, 1971) are crucial components:
- Fluid intelligence involves innate abilities like problem-solving and abstract thought.
- Crystallized intelligence encompasses acquired knowledge and skills gained through experience and education.
- Assessing fluid intelligence uses figural/pattern-based tests; crystallized intelligence is evaluated through verbal tests and knowledge assessments.
Personality
- Personality encompasses how individuals adapt their temperament, emotions, information processing, motivation, and interests to environmental demands (Wendy Johnson).
- Personality impacts how people think, feel, and act.
- Key personality dimensions include traits such as those measured by the Big Five:
- Openness to experience (creativity, curiosity)
- Extraversion (sociability, assertiveness)
- Neuroticism (emotional instability, anxiety)
Personality and Intelligence
- Both personality and intelligence are influenced by genetics and exhibit stability across situations and time.
- Personality is multi-dimensional, not a single capacity.
- Typical performance measures general behavior; maximal performance assesses behavior under optimal conditions.
- Personality and intelligence assessments are used in research (description, prediction, explanation) and practice (selection, diagnosis, classification).
- Changes in personality and intelligence can be categorized as quantitative (magnitude/intensity changes) or qualitative (nature/structure changes).
Basic Genetics
- Dominant traits are expressed if inherited from at least one parent.
- Recessive traits are expressed only if inherited from both parents.
- Genotype refers to the genetic makeup (inherited genes).
- Phenotype represents observable traits resulting from the genotype.
- Environment plays a crucial role in shaping both genotype expression and phenotypic development; these interact profoundly.
