Analysis of data from an earlier paper by the writer (Baker, 1958) shows that perceptual performance does not necessarily deteriorate daring a typical vigilance task. It was hypothesized that a major determinant of such deterioration is the regularity of signal appearance. An experiment is described here which supports this hypothesis. It is further demonstrated that motor activity markedly increases during a vigilance task, the least active subjects tending to detect more signals.
