Abstract:

Much of the variability in judgments of univariate sounds depends on what stimuli occurred recently sequence effects, and what stimuli might occur set and range effects. A model examined in this report associates much of this response variability with two factors, assimilation in memory and how subjects adjust for assimilation in order to maintain a veridical response scale. Studies of univariate stimuli reported here show sequence effects that are consistent with the model and not consistent with an attention-band model. Context effects in multidimensional judgments were also examined. Identification of these multidimensional stimuli was superior to that of univariate stimuli, but responses again assimilated toward the value of the prior stimulus. Keywords Psychoacoustics Auditory signal intensity Sequence effects Memory psychology Judgment psychology.
