Abstract : Forty male Ss were given a simple reaction time (RT) test with four ready-signal conditions, 10 Ss in each condition. A fifth group of 12 Ss received all four ready-signal conditions in a counterbalanced order on consecutive days. The results indicated that a 90-db ready-signal produced the slowest mean RT, 30-db the fastest, 60-db intermediate, while a random combination of ready-signals with a mean of 60-db also produced intermediate RTs. It was concluded that the ready-signal served as an adaptation stimulus against which the response-signals were perceived. (Author)
