Study Notes

Measuring Intelligence

The measurement of intelligence involves assessing an individual's performance on diverse tests and tasks that are tailored to their developmental level.
The process provides a standardized environment to observe the examinee's approach to various tasks.

Piaget's Stages of Cognitive Development

This theory is not discussed in the text.

Tests of Intelligence

Several factors contribute to a test's appeal, including the underlying theory, ease of administration and scoring, interpretability of results, adequacy of norms, reliability and validity indices, and cost-benefit analysis.

Stanford-Binet Intelligence Scales

The fifth edition of the Stanford-Binet (SB5) is designed for individuals aged 2 to 85 (or older).
It yields a Full Scale IQ derived from ten subtests, each having a mean of 10 and a standard deviation of 3.

Stanford-Binet Intelligence Scales: Composite Scores

The SB5 provides other composite scores, including an Abbreviated Battery IQ, Verbal IQ, and Nonverbal IQ, all having a mean of 100 and a standard deviation of 15.
The test also yields five Factor Index scores corresponding to the five factors it measures: Fluid Reasoning, Knowledge, Quantitative Reasoning, Visual-Spatial Processing, and Working Memory.

CHC and Corresponding SB5 Factors

The CHC theory identifies specific cognitive abilities and their relation to SB5 factors.
Fluid Intelligence (Gf), measured by the Fluid Reasoning (FR) factor: novel problem-solving, understanding relationships, and non-culturally bound reasoning.
Crystallized Knowledge (Gc), measured by the Knowledge (KN) factor: skills and knowledge acquired via formal and informal education.
Quantitative Knowledge (Gq), measured by the Quantitative Reasoning (QR) factor: mathematical knowledge, including number concepts, estimation, problem solving, and measurement.
Visual Processing (Gv), measured by the Visual-Spatial Processing (VS) factor: pattern recognition, spatial orientation, and understanding visual relationships.
Short-Term Memory (Gsm), measured by the Working Memory (WM) factor: temporarily storing, transforming, or sorting information in memory.

Stanford-Binet: Psychometric Soundness

The internal consistency reliability of the SB5 Full Scale IQ was determined using Nunnally's (1967) formula for the sum of multiple tests.

General Types of Items Used in Wechsler Tests

Picture Completion: identifying missing parts in pictures, drawing on visual perception, attention to detail, and differentiation of essential and nonessential information.
Picture Arrangement: rearranging scrambled picture cards to create a coherent story, assessing comprehension, attention, concentration, and understanding cause-and-effect relationships.
Block Design: replicating a design using colored blocks, measuring perceptual-motor skills, psychomotor speed, and analysis/synthesis abilities.
Object Assembly: assembling cut-up pictures of familiar objects, testing pattern recognition, assembly skills, and psychomotor speed.
Coding: applying Morse code to letters, measuring attention, learning ability, psychomotor speed, and concentration.
Symbol Search: searching for a target symbol in a group of symbols, evaluating cognitive processing speed.
Matrix Reasoning: completing an incomplete matrix, assessing perceptual organization and reasoning.
Word Reasoning: identifying the common concept described by clues, evaluating verbal abstraction and alternative concept generation.
Picture Concepts: selecting pictures sharing a common characteristic, assessing categorical reasoning and abstraction.
Cancellation: marking targeted images within a time limit, evaluating visual selective attention.

Wechsler Adult Intelligence Scale (WAIS-IV)

The WAIS-IV is designed for individuals aged 16 to 90 years, 11 months.
It consists of core and supplemental subtests:
- Core subtests are used to obtain composite scores.
- Supplemental subtests provide additional clinical information or expand the range of abilities assessed.

WAIS-IV Subtests Grouped by Indexes

Verbal Comprehension Scale: Similarities, Vocabulary, Information, Comprehension.
Perceptual Reasoning Scale: Block Design, Matrix Reasoning, Visual Puzzles, Picture Completion, Figure Weights (ages 16-69).
Working Memory Scale: Digit Span, Arithmetic, Letter-Number Sequencing (ages 16-69).
Processing Speed Scale: Symbol Search, Coding, Cancellation (ages 16-69).

WAIS-IV Psychometric Soundness

Studies have demonstrated the reliability, validity, and overall psychometric soundness of the WAIS-IV.
The WAIS-IV exhibits high internal consistency reliability for all subtests and composite scores.
