NCED Cognitive Assessment & Intelligence Testing 2 — Questions and Answers
Question 1: In the context of intelligence testing, which concept best describes the general cognitive ability that accounts for positive correlations among diverse mental tests?
- A measure of specific academic achievement skills
- A general factor (g) proposed by Spearman underlying all cognitive performance (Correct answer)
- A composite score derived from verbal subtests only
- A cultural adjustment factor applied to raw scores
Correct answer: A general factor (g) proposed by Spearman underlying all cognitive performance
Spearman's 'g factor' represents a general cognitive ability that explains why individuals who score well on one type of mental test tend to score well on others.
Question 2: Which theoretical model provides an alternative interpretive framework for the Kaufman Assessment Battery for Children, Second Edition (KABC-II) alongside CHC theory?
- Gardner's Theory of Multiple Intelligences
- Luria's neuropsychological processing model (Correct answer)
- Vygotsky's Zone of Proximal Development
- Bloom's Taxonomy of Cognitive Objectives
Correct answer: Luria's neuropsychological processing model
The KABC-II can be interpreted through either CHC theory or Luria's neuropsychological model, which organizes abilities into Sequential, Simultaneous, Planning, and Learning processes.
Question 3: A student scores at the 16th percentile on a cognitive assessment. What does this indicate?
- The student scored higher than 84% of peers in the normative sample
- The student scored equal to or higher than only 16% of the normative sample (Correct answer)
- The student's score falls in the average range
- The student did not meet the minimum passing threshold
Correct answer: The student scored equal to or higher than only 16% of the normative sample
A score at the 16th percentile means the student performed equal to or better than only 16% of the normative sample, placing them below 84% of their peers.
Question 4: On most individually administered intelligence tests, standard scores (composite/index scores) are set with a mean of 100. What is the corresponding standard deviation?
- 10
- 3
- 15 (Correct answer)
- 50
Correct answer: 15
Most intelligence test composite and index scores use a metric with a mean of 100 and a standard deviation of 15, allowing for cross-test comparison.
Question 5: Interpreting patterns of broad and narrow cognitive ability strengths and weaknesses across multiple test batteries is most consistent with which assessment approach?
- Single-score approach relying solely on the FSIQ
- Cross-battery assessment using CHC theory (Correct answer)
- Criterion-referenced assessment comparing to grade-level benchmarks
- Curriculum-based measurement using classroom tasks
Correct answer: Cross-battery assessment using CHC theory
Cross-battery assessment based on CHC theory systematically integrates scores from multiple batteries to provide a more complete profile of a student's broad and narrow cognitive abilities.
Question 6: Which type of reliability is most critical to consider when re-evaluating a student with the same cognitive battery after a three-year interval?
- Internal consistency reliability
- Test-retest reliability (Correct answer)
- Inter-rater reliability
- Split-half reliability
Correct answer: Test-retest reliability
Test-retest reliability measures the stability of scores over time, which is essential for determining whether observed score changes in a re-evaluation reflect true differences or measurement error.
Question 7: When standard scores from different cognitive test batteries come from different normative samples, the educational diagnostician should:
- Average the scores directly across batteries
- Use only one battery and discard results from others
- Interpret cross-battery comparisons cautiously and note normative differences (Correct answer)
- Convert all scores to percentile ranks before making any comparison
Correct answer: Interpret cross-battery comparisons cautiously and note normative differences
Because different normative samples may vary in composition and quality, direct comparison of scores across batteries requires caution and transparency about potential normative differences.
