In-Depth Notes on Theories and Approaches of Human Intelligence

Pioneering Work:
- Initiated the study of individual differences in the late 19th century.
- First to measure individual differences in intelligence.
Theory of Intelligence:
- Intelligence as a function of sensory acuity; individuals with high sensory discrimination are considered highly intelligent.
Key Qualities Proposed:
- Energy: Capacity for labor.
- Sensitivity: Awareness and responsiveness to environmental stimuli.
Negative Perception:
- Held negative views towards individuals in lower ranges of intelligence.
Anthropometric Laboratory:
- Located at South Kensington Museum, London.
- Conducted various tests on sensitivity (e.g., weight discrimination, taste tests, olfactory tests).
Main Publications:
- Hereditary Genius (1869) - emphasized the role of heredity in intelligence.

Profession: French psychologist who co-devised the Binet-Simon scale with Theodore Simon.
Definition of Intelligence:
- Components include reasoning, judgment, memory, and abstraction.
- Viewed intelligence as a measure of general mental ability reflected in intelligent behaviors.
Purpose of Intelligence Testing:
- To classify individuals rather than measure intelligence quantitatively.
Important Contributions:
- Involved in a 1904 commission to aid in identifying retarded children in Paris.
- Developed 30 tests in an ascending order of difficulty aimed at assisting in educational placement.
Core Components of Intelligence:
- Judgement, exemplified by individuals like Helen Keller.
- Three elements identified: Direction, Adaptation, and Control.
Types of Intelligence Introduced:
- Ideational: Creative thought processes.
- Instinctive: Natural, instinctual responses.
Additional Concepts:
- Mental Age: Age at which individuals can successfully complete certain tasks relating to intelligence.
- Mental Orthopedics: Techniques aimed at improving a child's intellectual capabilities.

Definition of Intelligence:
- Described intelligence as "the aggregate or global capacity of the individual to act purposefully, to think rationally and to deal effectively with his environment" (Wechsler, 1944).
Focus:
- Emphasized higher cognitive processes and was instrumental in developing intelligence tests for different age groups:
- WAIS: Wechsler Adult Intelligence Scale (16 years and older).
- WISC: Wechsler Intelligence Scale for Children (ages 6 to 16).
Test Components:
- Consists of verbal tests (information, similarities, arithmetic, vocabulary, comprehension, digit span) and performance tests (picture completion, picture arrangement, block design, object assembly, coding).

Three Components:
- Analytical/Componential Intelligence:
- Involves problem-solving through analysis and evaluation.
- Assessed through traditional IQ tests; linked to academic success.
- Components:
  - Meta-component: Executive functions managing cognitive processes.
  - Performance Component: Actual execution of tasks.
  - Knowledge Component: Obtaining and applying information.
- Creative/Experiential Intelligence:
- Entails deriving new ideas or solutions using imagination and prior experiences.
- Extremely important in novel problem-solving situations; associated with innovators and inventors.
- Components:
  - Automation: Processes that occur with little conscious effort.
  - Novelty: Ability to formulate new ideas.
- Practical/Contextual Intelligence:
- Ability to apply knowledge to navigate real-world situations and challenges.
- Understanding of adapting, shaping, or selecting environments for effective functioning (i.e., "Street Smarts").
- Reflects adaptability and efficiency in day-to-day decisions and actions.
