Abstract:This investigation was designed to study the effects of the antihistamine, chlorpheniramine maleate, as well as the influence of age and gender, singly and in combination with chlorpheniramine maleate, on selected types of performance tasks. It was hypothesized that chlorpheniramine maleate would have a negative effect on a wide range of task performance and self-report measures of mood and performance capability, much as it did in previous research (Gilliland, Schlegel, & Nesthus, 1997). Increasing age was hypothesized to have a negative effect on performance, especially on dual tasks and those tasks that emphasized tracking or speeded responses. If gender differences emerged, it was hypothesized that men may have some advantage on tracking or speeded tasks, whereas women may have some advantage on verbal or memory-based tasks. A total of 96 individuals representing two groups of women (25-30 years and 40-45 years of age) and three groups of men (25-30 years, 40-45 years, and 50-55 years of age) served as participants in the study. Participants were trained extensively and then performed a battery of performance tasks and provided self-report measures both prior to and following randomly presented, double-blind placebo and drug (4 mg chlorpheniramine maleate) conditions conducted on two consecutive days.
