Previous research into deliberate forgetting has primarily been carried out with verbal material. In a modified Sternberg task, Oberauer (2001) found longer response times when rejecting no longer relevant probes relative to control probes. This 'intrusion cost' was seen as evidence that no longer relevant material remains activated in memory, thereby triggering a familiarity signal that must be overwritten by recollection processes to reject the probe as not to-be-remembered. / Using a modified nonverbal Sternberg task, the aims of the studies presented in this dissertation were to investigate (1) whether similar processes could be observed in nonverbal memory, and (2) whether the familiarity signal underlying the intrusion cost is solely based on long-term memory traces. Results suggested that, at least in nonverbal memory, the intrusion cost may no.t entirely be driven by long-term memory, but that perceptual processes may also be involved. Findings were discussed in light of the debate on the dissociation of verbal and nonverbal memory, as well as current working memory models and our understanding of deliberate forgetting
