Study Notes
WISC-IV (Wechsler Intelligence Scale for Children)
- Designed for children aged 6 to 16 years.
- Provides Full Scale Intelligence Quotient (FSIQ) and four Index Scores.
- Report includes scaled scores for comprehensive analysis.
WISC-IV Test Results & Analysis
- Verbal Comprehension Index (VCI) includes subtests: Similarities, Vocabulary, Comprehension, Information, and Word Reasoning.
- Perceptual Reasoning Index (PRI) includes Block Design, Picture Concepts, Matrix Reasoning, and Picture Completion.
- Working Memory Index (WMI) includes Digit Span, Letter-Number Sequencing, and Arithmetic.
- Processing Speed Index (PSI) includes Coding, Symbol Search, and Cancellation.
WISC-IV Structure and Indices
- FSIQ reflects general intellectual functioning.
- VCI assesses verbal concept formation and reasoning.
- PRI evaluates spatial processing and fluid reasoning abilities.
- WMI measures working memory capabilities.
- PSI indicates ability to process visual information quickly and accurately.
Evaluation Procedures: Discrepancies
- Evaluate verbal vs. performance intelligence (e.g., VIQ/PIQ or VCI/PRI).
- A significant VIQ > PIQ difference may indicate stronger verbal skills.
- Explore potential for difficulties in tasks requiring speed or visual motor skills.
Evaluation Procedures: Alternative Discrepancies
- Assess if PIQ > VIQ indicates possible language limitations for non-native speakers.
- Performance skills may be stronger, highlighting better visual-motor discrimination.
WISC-IV Strengths and Weaknesses
- Internal comparisons of subtest scores help identify significant differences in strengths/weaknesses.
- Use separate means for comparison against scaled scores instead of relying solely on FSIQ.
Learning Disabilities
- Compare WISC-IV results to WJ-III (Woodcock-Johnson Tests of Achievement) for comprehensive assessment.
WAIS-IV (Wechsler Adult Intelligence Scale)
- Assesses cognitive ability in individuals aged 16:0 to 90:11.
- Normed on a diverse sample based on age, race, sex, education level, and geography.
WAIS-IV Concept of Intelligence
- Defined as the global capacity to act purposefully, think rationally, and effectively interact with the environment.
WAIS-IV Interpretation
- Report includes chronological age and scores for FSIQ, VCI, PRI, WMI, PSI.
- Indicates percentile ranking within normative population.
- Establishes a confidence interval for true FSIQ.
WAIS Classifications
- Classifications based on FSIQ scores:
- 130+: Very Superior
- 120-129: Superior
- 110-119: High Average
- 90-109: Average
- 80-89: Low Average
- 70-79: Borderline
- 69 and below: Extremely Low (Mental Retardation)
WAIS-IV Composite Scores
- FSIQ represents general intellectual ability.
- Includes General Ability Index (GAI), Verbal IQ (VIQ), and Performance IQ (PIQ).
- VCI assesses verbal reasoning and knowledge.
- POI focuses on visual perception and spatial skills.
- Working Memory and Processing Speed indices evaluate immediate memory and visual processing speed.
WAIS-IV Scaled Scores
- Scaled score of 10 reflects average ability with a standard deviation of 3.
WAIS IQ Scores
- Mean score of 100 with a standard deviation of 15.
WAIS Learning Disabilities
- Use WJ-III for comparison in identifying learning disabilities.
WAIS: Identifying Strengths and Weaknesses
- Analyze subtest scores under each index.
- Strengths indicated by scores above 115; weaknesses noted if scaled scores drop significantly below normative data.
