Abstract : The study was undertaken to determine the effects of experimentally induced stress on the accuracy and speed with which individuals listened to and repeated messages. For a stress situation, subjects were required to perform a psychomotor task while listening to recorded word lists in the presence of noise. The following three levels of stress were investigated: (1) Listening and speaking task only. (2) Listening and speaking task plus a simple psychomotor task. (3) Listening and speaking task plus a complex psychomotor task. When an individual must perform simultaneously two sensory-motor tasks that require some degree of accuracy and speed, his performance in both tasks is affected adversely. The more complex the task, the greater the decrement in performance, and the more likely the individual is to show evidence of emotional stress. (Author)
