Normative neuropsychological data are provided from a sample of 365, recruited from a nonclinical population. The sample was divided evenly between males and females, although males were somewhat overly represented in the youngest group, and females were somewhat overly represented in the oldest group. The measures included the Trail Making Test, Seashore Rhythm Test, Finger Tapping, Grooved Pegboard, and Dynamometer. The limited number of measures was a result of the time available to study each subject. Normative data were stratified by sex, age, and educational level. The present data were discussed in relationship to previous normative studies and also in the context of the need for additional normative studies.

Fifty men (age M = 32.50; education M = 14.98 years) were administered the Wisconsin Card Sorting Test (WCST), Ruff Figural Fluency Test (FFT), Verbal Concept Attainment Test (VCAT) Trail Making Test, Parts A and B (TMT), and F-A-S Verbal Fluency at baseline and 12 months later. WCST, FFT, and VCAT scores improved significantly over a 12-month interval. In contrast, TMT and F-A-S scores did not change. Level of intellectual ability failed to moderate the effect of previous testing upon performance. Suggestions concerning the use of these measures in longitudinal research designs and clinical follow-up examinations are offered, and reliable change indices concerning these measures are included.
