Lecture 9: Intelligence Testing

What is the Singular Model of intelligence?

Intelligence reflects a single ability.

What is "g"?

General (single) intelligence.

What is the Plural Model of inteligence?

Intelligence reflects multiple abilities that may not relate to each other.

What is the Hierarchical Model of intelligence?

Intelligence reflects a global intelligence factor "g" and ability-specific factors (i.e., it blends singular and plural models).

What model of intelligence do most current intelligence tests follow?

Hierarchical Model

What is the WAIS-5?

Wechsler Adult Intelligence Scale (version 5), which is used to assess adult intelligence according to a hierarchical model

What are the five subscales on the WAIS-5?

Verbal Comprehension, Verbal Spatial Processing, Fluid Reasoning, Working Memory, and Processing Speed

What does the Verbal Comprehension Index assess?

Verbal concept formation and verbal reasoning

What does the Visual Spatial Processing Index measure?

Spatial processing and visual-motor integration

What does the Fluid Reasoning Index assess?

Deductive reasoning and logical thinking

What does the Working Memory Index assess?

Capacity to store, transform, and recall incoming information / data in short-term memory

What does the Processing Speed Index assess?

Ability to rapidly and accurately process simple or rote information

What are the five major components of intelligence that emerge in numerous studies?

Verbal Comprehension, Verbal Spatial Processing, Fluid Reasoning, Working Memory, and Processing Speed

What is the Full Scale IQ Score?

Average performance across five intelligence scales on WAIS-5

What is the General Ability Index?

Average performance across the Verbal Comprehension, Visual Spatial Processing, and Fluid Reasoning scales on WAIS-5

What is norm-referenced assessment?

An individual's score on a measure is scaled relative to scores in a comparison (normative) sample

How are IQ scores scaled on the WAIS-5?

An individual's score on the WAIS-I5 is scaled relative to scores of same-age peers in a normative sample

What is the average score on the WAIS-5?

100

What is the range of "Average" scores on the WAIS-5?

90-109

What percentage of people who complete the WAIS-5 are classified in the "Gifted" or in the "Impaired" ranges?

2.2% each (or 4.4% total)

Is the standardization of the WAIS-5 high or low?

High

Are the internal consistency and test-retest reliability of the WAIS-5 high or low?

High

Is the utility of the WAIS-5 high or low?

High

Does the WAIS-5 predict initial grades in school or success after getting a job or both?

Only initial grades in school

What does the WAIS-5 predict about academic performance in college?

Academic performance in only the first year of college

Does the WAIS-5 predict success after getting a job, whether someone gets a job, or both?

Only whether someone gets a job

Which of the following factors are related to IQ scores on the WAIS-5: Educational background, cultural background, motivation, anxiety, socioeconomic status, and/or physical testing conditions?

All of them

True or False: Genetic influences on the WAIS-5 are single-gene.

False

True or False: Intelligence is assumed to be "normally distributed" throughout the population.,

True

Which of the following environmental factors have an influence on IQ scores on the WAIS 5: environmental toxins, variables associated with low SES (socioeconomic status), breast-feeding?

All of them

True or False: The WAIS-5 adequately assesses emotional intelligence and social intelligence.

False

True or False: The heritability of intelligence is lower in low-SES families.

True

True or False: What is meant by the concept of intelligence is more narrow than what is assessed by the WAIS-5.

True
