Abstract
An experiment is described, using 20 Ss in a serial auditory RT task, which demonstrates sequential effects of manipulation of stimulus intensity from trial to trial. No such effects are demonstrated with the manipulation of pitch of stimuli. The obtained results confirm predictions from a statistical decision model of simple RT and are interpreted as an adaptation level effect. The finding is utilised to explain previously established differences between the performance of normals and schizophrenics in serial RT tasks.Keywords
