Abstract:

Results of the past year are consistent with a model having two assumptions Successive sounds are remembered as overly similar, and subjects attempt to correct for this by adjusting their response scales. This holds for unidimensional and multidimensional stimuli. In addition, when two dimensions are varied loudness and pitch were examined here but only one is judged, trial-to-trial variations of the other dimension interfere with performance. The magnitude of this interference is greater when the other, irrelevant dimensions varies by larger amounts. Keywords Psychoacoustics Adjustmentpsychology Auditory perception classification.
