Three-dimensional haptic matrices were pilot-tested as a nonvisual measure of cognitive ability. The results indicated that they correlated with convergent measures, with emphasis on spatial processing and that the participants who described items “visually” completed them more quickly and accurately and tended to have become visually impaired more recently than the other participants.

An individual's cognitive effectiveness directly effects their decision making ability, thus effecting their performance. an important aspect for assessing fitness for duty is determining cognitive effectiveness. Reeves, Winter, LaCour, Raynsfor, Vogel, and Grissett (1991) designed a cognitive assessment measure, the Automated Neuropsychological Assessment Metrics version 3 (ANAM33, for assessing fitness for duty in individuals with an intellectual functioning ranging from superior to moderately impaired. The ANAM3 battery contains eight subscales for assessing cognitive abilities. The current research collected male and female normative data for ANAM3; specifically, the number of trials required to reach the learning asymptote for each subscale.third trial for all subscales. Additionally, across all subscales women performed better than men, four of which were significant: Memory Search (6 items), Spatial Processing, Procedural Reaction Time, Two-Choice Reaction Time. is provided. ThereforeThe participants all reached the learning curve asymptote by the An explanation for the gender difference

This study represents an initial exploration of a new technique developed to permit the assessment of age differences in the “useful field of view” (Ball, et al., 1993) while simultaneously operating a motor vehicle. Due to necessary safety precautions, this novel approach was first evaluated using a simulated rather than a real-world driving context. Data was collected from seventeen young (mean age = 19.8) and eight older (mean age = 72.9) adult volunteers. Preliminary data analyses indicated that the technique was sensitive to “tunnel vision” effects resulting from experimentally induced limitations in the time available to process stimulus target “onset” events in the visual periphery. The magnitude and time-course of these effects differed markedly as a function of the age of the observer. Shortcomings in the current implementation of the technique and planned improvements are also discussed.
