Abstract
The purpose of this study was to determine if a subconscious
detection effect exists in audio monitoring. The
vigilance task consisted of the detection of an audio signal
masked by thermal noise. Thirty signals over a sixty minute
watch were presented to eighteen military officers who were
divided into three equally numbered groups. The control
group monitored the tape and this was their primary task.
The other two groups were engaged in other primary tasks
and were asked to monitor the tape as a secondary task. A
statistical examination of the results indicated, at a low
probability level of p < .25, an effect was present causing
the groups engaged in monitoring . as a secondary task to detect
a greater percentage of the signals than the control group. The analysis also indicated that there was a significant
decline in performance over time.
