Effect of characteristics of target cues on task interference from prospective memory.
Event-related potential technique was used to examine the effect of characteristics of target cues on brain activity related to task interference during event-based prospective memory (PM). Three conditions were tested. In the control condition participants had no PM task and merely performed a shape decision task. In one PM condition the task of PM was to respond to a salient cue, whereas in the other PM condition the task of PM was to respond to a nonsalient cue. The results seemed to support preparatory attentional and memory processes theory and suggested frontal lobe involvement in monitoring, which caused task interference effects, and those characteristics of cues modulated the amount of task interference and the extent to which the frontal lobe was engaged.
