Abstract

While there are pointers relating to the consequences of repetition, a general framework regarding the cognitive implications of processing multidimensional stimuli as a function of previous stimulus history is currently lacking. Three experiments using sounds varying in location and pitch were carried out, in which the immediate consequences of repeating or changing task-relevant and task-irrelevant attributes were orthogonally examined. A consistent pattern of data was shown, in that the magnitude of selective attention failure was larger when the task-relevant value repeated across trials, while differences between dimensions were larger when the task-relevant value changed across trials. These effects of irrelevance and dimension as a function of intertrial contingency are summarized in a model depicting the dynamic allocation of processing resource.
