“…On the other hand, if prospective memory retrieval is spontaneous and does not require monitoring for cues at the time the target event is encountered (and immediately preceding the target event), high prospective memory performance can be obtained in the absence of task interference (see the multiprocess theory; McDaniel & Einstein, 2000). The results of research testing for task interference have been mixed (A.-L. Cohen, Jaudus, & Gollwitzer, 2008;Guynn, 2003;Marsh et al, 2003;Smith, 2003;Smith & Bayen, 2004;Smith et al, 2007), suggesting that the parameters of the ongoing and prospective memory tasks may determine whether prospective memory retrieval requires that attentional resources be allocated to the prospective memory task immediately prior to target events (but see Smith et al, 2007, for an alternative explanation).…”
