Which concept emphasizes the Case Study Approach in cognitive neuropsychology?

• A. The Case Study Approach
• B. Group Studies
• C. Functional MRI Analysis
• D. Lesion-Symptom Mapping

Answer: (A)

The Case Study Approach in cognitive neuropsychology emphasizes in-depth examination of a single patient or a small number of cases to infer how cognitive processes are organized. By analyzing exact patterns of deficits and preserved abilities within a case, researchers can uncover how different components interact and identify dissociations that reveal the architecture of cognition. This depth and focus on individual profiles often reveal insights that broad group data might miss, such as subtle distinctions between modules or the impact of unique lesion patterns.

Group studies, by contrast, aggregate data across many individuals to detect consistent patterns, which can obscure the nuances of a single case. Functional MRI analysis is a technique for measuring brain activity during tasks and can be used with individuals, but it is not itself about prioritizing single-case investigation. Lesion-symptom mapping relates brain damage to deficits across a sample, emphasizing cross-subject associations rather than detailed case-level exploration. Therefore, the case-focused approach is the best fit.
