We investigated the effect of short interruptions on performance of a task that required participants to maintain their place in a sequence of steps each with their own performance requirements. Interruptions averaging 4.4 s long tripled the rate of sequence errors on post-interruption trials relative to baseline trials. Interruptions averaging 2.8 s long--about the time to perform a step in the interrupted task--doubled the rate of sequence errors. Nonsequence errors showed no interruption… Expand
