Impact of ‘Irrelevant’ Information During Intertrial Intervals on Contingency Ratings
The occurrence of the co-absence of two potentially associated stimuli (D-cell events) influences contingency judgments. We previously found manipulating co-absence frequency had more effect than co-absence duration on contingency judgments. We hypothesized filling the co-absence periods with irrelevant information (‘Trash’) would better clear working memory, resulting in stronger learning. We have found this not to be the case and will discuss possible reasons for this observation.
