Foundations of Stimulus-Response/ Stimulus-Stimulus Compatibility

摘要

The two principal accomplishments during this period have been the successful extension of the dimensional overlap model to sequential effects, and the completion of Greg Stevens' dissertation. The sequential effects on which we have been focusing are the speed ups and slow downs of RT with repetitions and non-repetitions, respectively, of stimuli and/or responses in choice RT tasks - the so-called repetition effect. Of particular importance for the dimensional overlap model is the finding that the repetition effect interacts with S-R compatibility. We have now shown that the DO model can account for this interaction, as well as for the repetition effects of irrelevant stimuli, by postulating that the information requirements on repeated trials are less than on non repeated trials.
