The pre/post cueing technique in the study of selective attention

Previous studies using pre/post cueing to study selective perception have typically confounded the disruptive effects of the post-cue with the possible facilitative effects of the pre-cue. The present experiments were designed to control for post-cue delay and interference effects by varying presentation rate but with post-cue delay constant. With both dichotic and bisensory presentation pre/post differences were found to decrease as rate increased. This is interpreted as indicating that the pre-cue did enhance performance of the selection task, that is, that selection occurred during not after intake of the split-span list on pre-cued trials. The results are discussed in terms of perceptual selection and response selection theories of attention.
