Routing activity & Basal and Ceiling Scores

Administration of the SB-5

Verbal, Performance, & Full Scale Scores

Scales of the SB15

Fluid Reasoning (FR)

Knowledge (K)

Quantitative Reasoning (QR)

Visuo-Spatial Processing (VsP)

Working Memory (WM)

Domains Measured in the SB-5

(FR) Fluid Reasoning

Domain in the SB-5 characterized by the ability to solve verbal and nonverbal problems using inductive and deductive reasoning

(K) Knowledge

Domain in the SB-5 that involves a person’s accumulated fund of general information acquired at home, school, or work

(QR) Quantitative Reasoning

Domain in the SB-5 that characterizes an individual’s facility with numbers and numerical problem-solving, whether with word problem

(VsP) Visuo-Spatial Processing

Domain in the SB-5 that measures an individual’s ability to see patterns, relationships, spatial orientations, or gestalt among diverse pieces of a visual display

(WM) Working Memory

Domain in the SB-5 which is a class of memory processes in which diverse information stored in short-term memory is inspected, sorted, or transformed

Standard Scores

Three levels of IQ composite scores (FSIQ, VIQ, & NV IQ)

5 Factor Indexes (FR, K, QR, VsP, & WM)

Scoring of the SB-5

1905: Binet-Simon Scale

First version of the SB-5 with items arranged from easiest to hardest

1908 & 1911: Revisions of the Binet-Simon

Revision of the SB-5 that included Mental Age

1916: Stanford-Binet (The Americanization)

Version of the SB-5 brought about by Lewis Terman. He brought the scale to the US, translated, and added items. Where the first formula of IQ using Ratio IQ was introduced

1937: L and M forms

Two different versions of the SB-5 to avoid carryover effects and allow test-retest

1960: Form L-M

Combination of items from Form M and Form L. Removed old ratio IQ for deviation IQ

SB-4

Version of the SB-5 that uses a point scale format using an old profile of intelligence

Wechsler Adult Intelligence (WAIS-V)

A mixed power and speed intelligence test designed to provide a comprehensive measure of an individual's functioning based on the CHC Theory

16 y/0 0 months - 90 y/o 11 months

Target population of WAIS-V

Diagnosing intellectual disabilities or learning disorders

Identifying intellectual giftedness

Assessing cognitive strengths and weaknesses

Aids in neurological evaluations such as for traumatic brain injury or dementia

Uses of WAIS-V

Full-Scale IQ (FSIQ)

Primary Index Scores

Subtest Scaled Scores

Ancillary and Complementary Index Scores

Scores in WAIS-V

Full-Scale IQ (FSIQ)

The composite score in the WAIS-V that represents overall intellectual ability

Primary Index Scores

The five key scores in WAIS- V that measure cognitive abilities in distinct domains

Subtest Scaled Scores

In the WAIS-V, these are the individual scores for each subtest, with a mean of 10 and a standard deviation of 3

Ancillary and Complementary Index Scores

Additional scores in the WAIS-V that provide more specific clinical insights, such as nonverbal or quantitative reasoning abilities

Verbal Comprehension Index (VCI)

Visual-Spatial Index (VSI)

Fluid Reasoning Index (FRI)

Working Memory Index (WMI)

Processing Speed Index (PSI)

Domains measured in the WAIS-V, WISC-V, & WPPSI

Verbal Comprehension Index (VCI)

Domain in the WAIS-V that is the ability to use verbal reasoning and acquired knowledge

Visual-Spatial Index (VSI)

Domain in the WAIS-V that is the capacity to analyze, synthesize, and mentally manipulate visual information

Fluid Reasoning Index (FRI)

Domain in the WAIS-V that is the ability to solve novel problems and identify underlying patterns

Working Memory Index (WMI)

Domain in the WAIS-V that is the ability to hold and process information in short-term memory

Processing Speed Index (PSI)

Domain in the WAIS-V that is the quick and efficient processing of simple visual information

Wechsler Adult Intelligence (WAIS-IV)

Intelligence test designed to assess an individual’s intellectual functioning and cognitive strengths and weaknesses. Shifted from the old dual model of intelligence to the CHC

Diagnosis of intellectual disabilities and learning disorders

Insights into cognitive function following a brain injury, stroke, or in the context of degenerative conditions like dementia

Helping to identify an individual’s intellectual capabilities for academic or career guidance

Uses of the WAIS-IV

Full-Scale IQ (FSIQ), Primary Index Scores, & Subtest Scaled Scores

Scoring of the WAIS-IV

Verbal Comprehension Index (VCI)

Perceptual Reasoning Index (PRI)

Working memory Index (WMI)

Processing Speed Index (PSI)

Domains Measured in WAIS-IV

Perceptual Reasoning Index (PRI)

Domain exclusive to the WAIS-IV that assesses non-verbal reasoning visual-spatial processing, and visual-motor integration. It involves solving abstract, non-verbal problems and interpreting visual information.
