Variations in Psychological Attributes and Intelligence

Individual Differences in Human Functioning
- Individual differences refer to distinctiveness and variations among people's characteristics and behaviour patterns.
- Situationism: The perspective that situations and circumstances in which a person is placed play a dominant role in influencing behaviour. A person who is generally aggressive may behave submissively in the presence of a top boss.
Assessment of Psychological Attributes
- Assessment: The measurement of psychological attributes of individuals and their evaluation, using systematic and scientific procedures.
- Formal Assessment: Objective, standardised, and organised evaluation conducted by trained psychologists.
- Informal Assessment: Varies from case to case and assessor to assessor, making it open to subjective interpretation.
Domains of Psychological Attributes
- Intelligence: The global capacity to understand the world, think rationally, and use available resources effectively when faced with challenges.
- Aptitude: An individual's underlying potential for acquiring specific skills through appropriate environment and training.
- Interest: An individual's preference for engaging in one or more specific activities relative to others.
- Personality: Relatively enduring characteristics of a person that make her or him distinct from others.
- Values: Enduring beliefs about an ideal mode of behaviour that set standards for guiding action and judging others.
Main Assessment Methods
- Psychological Test: An objective and standardised measure of an individual's mental or behavioural characteristics.
- Interview: Seeking information from a person on a one-to-one basis.
- Case Study: An in-depth study of an individual in terms of her/his psychological attributes and history within her/his psychosocial and physical environment.
- Observation: Employing systematic, organised, and objective procedures to record naturally occurring behavioural phenomena in real time.
- Self-Report: A method in which a person provides factual information, opinions, or beliefs about herself/himself via questionnaires, interviews, or diaries.

Theories of Intelligence

Definitions of Intelligence
- Alfred Binet: The ability to judge well, understand well, and reason well.
- David Wechsler: The global and aggregate capacity of an individual to think rationally, act purposefully, and deal effectively with her/his environment.
- Howard Gardner and Robert Sternberg: An intelligent individual not only adapts to the environment, but also actively modifies or shapes it.
Psychometric / Structural Approach vs. Information-Processing Approach
- Psychometric Approach: Expresses individual performance as a single index of cognitive abilities, studying intelligence as an aggregate of abilities.
- Information-Processing Approach: Focuses on the cognitive processes, functions, and mechanisms underlying intelligent behaviour.
Major Psychometric Theories
- Uni-Factor / One-Factor Theory (Alfred Binet): Conceptualises intelligence as consisting of one similar set of abilities used for solving all problems in an environment.
- Two-Factor Theory (Charles Spearman, $1927$ ): Uses factor analysis to divide intelligence into:
  - g-factor (General factor): Primary mental operations common to all performances.
  - s-factor (Specific factors): Specific abilities that allow excellence in specialized domains (e.g., singing, architecture).
- Theory of Primary Mental Abilities (Louis Thurstone): Proposes $7$ independent primary mental abilities:
  - Verbal Comprehension (grasping meaning of words, concepts, ideas).
  - Numerical Abilities (speed and accuracy in computational skills).
  - Spatial Relations (visualising patterns and forms).
  - Perceptual Speed (speed in perceiving details).
  - Word Fluency (using words fluently and flexibly).
  - Memory (accuracy in recalling information).
  - Inductive Reasoning (deriving general rules from presented facts).
- Hierarchical Model of Intelligence (Arthur Jensen): Consists of two levels:
  - Level I (Associative Learning): Output is similar to input (e.g., rote learning and memory).
  - Level II (Cognitive Competence): Higher-order skills that transform input to produce an effective output.
- Structure-of-Intellect Model (J.P. Guilford, $1988$ ): Classifies intellectual traits along $3$ dimensions:
  - Operations ( $6$ ): Cognition, memory recording, memory retention, divergent production, convergent production, evaluation.
  - Contents ( $5$ ): Visual, auditory, symbolic, semantic, behavioural.
  - Products ( $6$ ): Units, classes, relations, systems, transformations, implications.
  - Total cells = $6 \times 5 \times 6 = 180$ cells.
Theory of Multiple Intelligences (Howard Gardner)
- Proposes $8$ independent types of intelligence:
  - Linguistic: Fluency and flexibility in language (poets, writers).
  - Logical-Mathematical: Abstract reasoning and problem solving (scientists, Nobel prize winners).
  - Spatial: Forming and transforming visual images (pilots, sailors, sculptors, painters, architects, surgeons).
  - Musical: Producing and manipulating musical rhythms and patterns.
  - Bodily-Kinaesthetic: Flexible/creative body movement (athletes, dancers, actors, sportspersons, surgeons).
  - Interpersonal: Understanding motives, feelings, and behaviours of others (psychologists, counsellors, politicians, social workers).
  - Intrapersonal: Awareness of one's own feelings, motives, identity, and meaning of life (philosophers, spiritual leaders).
  - Naturalistic: Recognizing features of the natural world, flora, and fauna (hunters, farmers, tourists, botanists, zoologists).
Triarchic Theory of Intelligence (Robert Sternberg, $1985$ )

Elements of Triarchic Theory of Intelligence

*   **Componential / Analytical Intelligence**: Analysis of information to solve problems. Contains three components:
    *   *Knowledge Acquisition Component*: Responsible for learning and acquiring ways of doing things.
    *   *Meta Component*: Higher-order executive process involved in planning what to do and how to do it.
    *   *Performance Component*: Actual execution of tasks.
*   **Experiential / Creative Intelligence**: Using past experiences creatively to solve novel problems and make new discoveries.
*   **Contextual / Practical Intelligence**: Ability to deal with daily environmental demands ("street smartness" or
