ブロックレベルの競合適応は課題間で般化するのか

The present study investigated whether the modulation of the compatibility effect depending on conflict frequency in a given block (the proportion of compatible trials) generalizes from one kind of conflict to another. To test this, we conducted four experiments using a combined-conflict paradigm involving the Simon and Spatial Stroop tasks. We manipulated the conflict frequency (high/low) in one of the two tasks, while the conflict frequency in the other task was 50%. We focused on the block-wise conflict adaptation associated with conflict frequency in both tasks. The results of the four experiments showed that the block-wise conflict adaptation effect appeared only for the task in which conflict frequency was manipulated. These results suggest that the block-wise adaptation associated with conflict frequency does not generalize from the Simon task to the Spatial Stroop task or vice versa.
