Step 1: Understanding the Concept:
The question requires matching psychological tests and syndromes with their correct descriptions. This involves knowledge of intelligence testing (specifically Wechsler scales) and characteristics of certain genetic syndromes.
Step 2: Detailed Explanation:
Let's perform the correct logical matching first:
A. Picture completion is a subtest from the Wechsler scales where a person identifies a missing part in a picture. It is a non-verbal task and is classified as a I. Performance test. So, A matches I.
B. Similarities is another Wechsler subtest that assesses abstract verbal reasoning by asking how two things are alike. It is classified as a III. Verbal test. So, B matches III.
C. Down Syndrome is a genetic condition characterized by a range of intellectual disability, where the IQ is often in the mild to moderate range, and can be II. Usually IQ below 50. So, C matches II.
D. William Syndrome is a rare genetic disorder where individuals often have a IV. Low IQ with musical talent and strong social skills. So, D matches IV.
The logically correct matching is A-I, B-III, C-II, D-IV. This sequence is not available in the options, indicating a likely error in the question's options.
Step 3: Evaluating the Given Options:
In situations with flawed questions, the strategy is to select the option that is "most correct." Let's analyze Option (A): A-I, B-II, C-III, D-IV.
A-I is correct.
B-II (Similarities - Usually IQ below 50) is incorrect.
C-III (Down Syndrome - Verbal test) is incorrect.
D-IV is correct.
This option contains two correct pairings (A-I and D-IV). The pairings for B and C appear to have been swapped. Given the choices, this is the best available option as it correctly identifies the start and end pairs.
Step 4: Final Answer:
Despite the clear errors in the pairings for B and C, option (A) is the intended answer as it contains the most correct individual matches.
