Summary: | Describes 3 models (the linear additive learning model, the exponential additive learning model, and the independent trace model) of sequential effects in psychophysical tasks. These models were tested using data from a study by W. S. Verplack et al . The models appear to be most consistent with the independent trace model in which the momentary value of the criterion is modified by memory traces, an independent trace being retained for each relevant past event. On this basis, a theory of criterion setting is developed: A long-term process determines an initial value for the criterion, and 2 short-term processes adjust the criterion to match current changes in the expected probabilities of signals and to maximize the information transmitted by the S's responses. The theory is applied to results in the literature. (65 ref) |
