Disjunctive Reaction Time as it Relates to Complexity Level

The reaction time for subject with increase complexity is the focus of this study. The ten respondents were randomly selected on the campus of University Wisconsin at Milwaukee. Ten subjects reaction time was evaluated with a computer simulation program using one, two, or four choice trails, which lasted forty to sixty minutes. The data were analyzed using t test and ANOVA. The t test showed no significance as far as practice effects were concerned, but inferences can be made. Also the ANOVA showed a significant difference with reaction time as it relates to complexity. I found that as the level of complexity increase so does the reaction time.

Disjunctive Reaction Time Measure as it relates to Complexity of Task

This study was conducted to prove that reaction time increases as the level of complexity increases. Disjunctive reaction time was measured to eliminate subject reacting too early to the stimulus. Also make the tack more complicated and for subject to uses discrimination before responding to stimulus. Postman and Egan (1949) defines disjunctive reaction time as "two or more different stimuli are presented in random order…the subject is instructed to react to one but not to the other stimuli"(p 240). Rikli and Busch (1986) defined reaction time "as the latency from the onset of the visual stimulus to the depression of the microswitch"(p 646). Although a joystick was used to respond to the visual stimulus the same principle applies. For the purposes of this study both definition of reaction time were incorporated to facilitate proper measurement.
