利用前额叶功能的神经心理学模型，作者研究了健康志愿者个体间前额叶功能差异的模式。使用相关性和极端组的方法，他们比较了言语和视觉空间的工作记忆能力与执行控制的措施，并在直接和间接的语义启动任务作为衡量语义访问的Stroop干扰任务的性能。低视觉空间工作记忆能力的受试者表现出增加Stroop干扰低文字记忆能力的受试者表现出增加启动和Stroop干扰。这项研究表明，前额叶功能在个体之间存在差异，形成了表现差异的模式。这些结果表明，工作记忆，执行控制，语义提取在一定程度上的功能相关。
Using neuropsychological models of prefrontal function, the authors investigated the pattern of interindividual prefrontal performance differences in healthy volunteers. Using a correlation and an extreme group approach, they compared verbal and visuospatial working memory capacity with performance on the Stroop interference task as a measure of executive control and on the direct and indirect semantic priming tasks as a measure of semantic access. Subjects with low visuospatial working memory capacity exhibited increased Stroop interference Subjects with low verbal memory capacity showed increased priming and Stroop interference only. The study shows that prefrontal functioning varies interindividually, forming patterns of performance differences. These findings suggest that working memory, executive control, and semantic retrieval are functionally related to some extent.
