Abstract:
Patients' cognitive complaints and subsequent performance on neuropsychological tests often fail to relate. This could, in part, be caused by a Babylonic incongruence between laypeople's and experts' use of cognition words or "jargon." The present study examined the concurrency of experts and laypeople for 18 neuropsychological tests in the cognitive domains "language," "memory," "attention/concentration," "perception," and "thinking" (executive functioning). This was done by correlating the classifications of the laypeople and experts for individual tests and within each domain. A high domain concurrency was found, indicated by domain correlations of the classifications between laypeople and experts ranging from r(s)=.79 to .92, with exception of the domain "attention" (r(s)=.32). Importantly, with respect to the classification of each individual test in a cognitive domain, large variations in correlations were found, ranging from r(s)=.30 up to r(s)=1.0. These results indicate that there is agreement between the concepts laypeople use and the theory-based concepts of the experts. Our study also offers valuable insight for the clinical practice: tests with a high correlation should be used to aid the clarity of communication in the clinical practice, for instance when giving feedback on performance.

E. C. Tolman's theory of purposive behavior emphasizes that much behavior is goal-directed. He argued that to understand behavior, we must look at the entire sequence of actions leading to a goal. For instance, high school students study hard, not just due to past reinforcement but also to achieve the goal of getting into a good college.
