Stimulus similarity and retroactive interference and facilitation in monkey short-term memory.

Abstract: Four experiments examined the effects of similarity between the sample and an interpolated stimulus in a modified delayed-matching-to-sample (DMTS) paradigm. The basis trial sequence was as follows: (a) a sample was presented, and the response to it was either rewarded or nonrewarded, (b) an interpolated stimulus was presented, and the response to it was either rewarded or nonrewarded, and (c) after a delay interval a choice test was given between the initial sample and a new stimulus, with the sample being co… Show more

“…In particular, the observed pattern of lSI and delay effects suggests adding the assumption that information from both short-and long-term memory influences DMTS performance and that interactions among processes in short-term memory give rise to nonindependence of stimulus events. Experiments varying the similarity of alternative sample stimuli reinforce this conclusion (Medin et al, 1980).…”

“…A number of investigators (e.g., Medin, Reynolds, & Parkinson, 1980;Spear, 1976;Zentall, 1970) have emphasized the importance of reinstatement and retrieval cues in memory processing. In a DMTS paradigm, the sample stimulus appears alone and in a different location (in the present experiment, over the center foodwell) compared with the choice test setting (in which the objects cover the outside foodwells).…”

“…One approach to this problem is to present an interpolated (and usually irrelevant) stimulus during all or some portion of the delay Waxman, 1977;Grant, 1976;Roberts & Grant, 1974). The contribution of comparison observation and choice (sometimes referred to as "response output") to overall performance is no less important (Medin, Reynolds, & Parkinson, 1980;Wright & Sands, 1981). One purpose of the present study, therefore, was to determine whether, and to what extent, extraneous stimulation would affect delayed matching when introduced during trial periods other than the delay interval.…”

“…Similarity of the interpolated stimuli to the sample and test stimuli, and saliency, familiarity, and complexity of the interpolated stimuli are not significant sources of retroactive interference (Grant & Roberts, 1976;Medin et al, 1980;Wright et al, 1981). Both ambient illumination and localized keylight illumination interpolated into the delay interval of delayed matching interfere with matching accuracy (Grant & Roberts, 1976).…”

“…Retroactive interference is observed when matching accuracy on the interpolated test trials declines relative to matching accuracy on the baseline trials (Grant & Roberts, 1976;Medin, Reynolds, & Parkinson, 1980;Moise, 1970;Wright, Urcuioli, Sands, & Santiago, 1981).…”
