Step 1: Concept Identification: The task is to associate the four primary index scores of the Wechsler Intelligence Scale for Children—Fourth Edition (WISC-IV) with their respective core subtests.
Step 2: Detailed Analysis:
A. Verbal Comprehension Index (VCI): Assesses verbal concept formation and reasoning. The subtest I. Similarities, involving explanations of word associations, is a core VCI component.
B. Perceptual Reasoning Index (PRI): Evaluates non-verbal and fluid reasoning. The subtest III. Picture Concepts, requiring the selection of pictures with shared characteristics from different rows, is a core PRI component.
C. Working Memory Index (WMI): Measures attention, concentration, and mental control. The subtest II. Digit Span, which requires recalling number sequences forwards and backwards, is a core WMI component.
D. Processing Speed Index (PSI): Assesses the speed of mental and graphomotor processing. The subtest IV. Coding, involving the rapid matching of symbols to numbers, is a core PSI component.
The correct pairings are A-I, B-III, C-II, and D-IV.
Step 3: Conclusion: The correct sequence of matches is A-I, B-III, C-II, D-IV, corresponding to option (B).
