5 Ss were required to respond as rapidly as possible to auditory signals of threshold, 34, 48, and 88 db intensity, mixed within the same 2-hr. session. Reaction time increased over time for all signal intensities, but the increase was larger for the threshold signal. There were two kinds of increase, one independent of signal intensity transferring the entire distribution toward longer reaction times. The other kind of increase was dependent on signal intensity and increased the number of long reaction times for the threshold signal.

Male and female Ss performed a two-component monitoring task under 3 conditions of stress, No-stress, Task-related Stress, and Task-unrelated Stress. Dependent variables were reaction time, cumulative responses, and cumulative response errors. The results indicated faster reaction time under conditions of Task-related Stress than during the other two conditions. Differences in cumulative responses and cumulative response errors also occurred over monitoring periods, suggesting improved vigilance with practice. The results were interpreted as indicative of a “protective-adaptive” response to stress, during which S protects himself by adapting within his response repertoire to stressors.
