Four experiments concerned with human information processing are reported. The first investigates a number of factors that may affect performance on a visual search task. On the basis of the data all current models of visual search seem incomplete. The second experiment examined some stimulus parameters that influenced detection performance in a vigilance task. Some recommendations of potentially practical significance may be made on the basis of these results. The third experiment studied some cognitive aspects of the control of selective attention. The fourth, a Ph.D. thesis, uncovered evidence for two rather different modes of perceptual processing analytic and structural. Author
