“…The findings discussed here are also consistent with other reports of increased false recognition in patients with frontal lobe lesions [9,10,12,14,57,68,80] and in normal elderly individuals [30,70] demonstrated on both verbal and nonverbal memory tasks. Along these lines, it is important to emphasize that although we focused here on the role of PFC in face memory, we do not wish to suggest that false recognition in individuals with frontal lobe dysfunction is necessarily domain-specific.…”

Abstract. Patients with frontal lobe damage and cognitively normal elderly individuals demonstrate increased susceptibility to false facial recognition. In this paper we review neuropsychological evidence consistent with the notion that the common functional impairment underlying face memory distortions in both subject populations is a context recollection/source monitoring deficit, coupled with excessive reliance on relatively preserved facial familiarity signals in recognition decisions. In particular, we suggest that due to the breakdown of strategic memory retrieval, monitoring, and decision operations, individuals with frontal lobe impairment caused by focal damage or age-related functional decline do not have a reliable mechanism for attributing the experience of familiarity to the correct context or source. Memory illusions are mostly apparent under conditions of uncertainty when the face cue does not directly elicit relevant identity-specific contextual information, leaving the source of familiarity unspecified or ambiguous. Based on these findings, we propose that remembering faces is a constructive process that requires dynamic interactions between temporal lobe memory systems that operate in an automatic or bottom-up fashion and frontal executive systems that provide strategic top-down control of recollection. Executive memory control functions implemented by prefrontal cortex play a critical role in suppressing false facial recognition and related source memory misattributions.

“…Preserved cued recall and impaired free recall on the one hand, and preserved or better recognition than recall on the other, have both been described previously in frontal patients (e.g. Hanley et al 1994;Parkin et al,1994;Volpe & Hirst, 1983). Source memory errors and temporal order memory impairment are usually assumed to be linked with frontal lobe dysfunction (e.g.…”

“…It has been argued that preserved recognition and cued recall are, indeed, evidence for intact memory verification processes (e.g. Hanley et al, 1994;Parkin, Yeomans, & Bindschaedler, 1994). This would imply that PAD would have a selective deficit in the search processes.…”

Confabulation is usually assumed to result from a deficit in either the memory verification processes alone or in both the search and the verification processes. The present study concerns a patient who, in contrast to other patients, displayed confabulations but had preserved memory verification abilities. She exhibited only a selective impairment of the search processes. Recognition abilities were preserved, and cued recall was better than free recall. On the latter task, she recalled fewer correct items and produced more intrusions than control subjects. The patient had normal performance in several tests usually assumed to tap "executive functions." It is thus concluded that an impairment in verification, regardless of whether it is specific or not to memory, is not a necessary component of confabulations. The case is discussed in relation to two memory control processes models

“…One interesting proposal is that the yes/no and forced-choice procedures may assess recollection and familiarity differently (Bastin & Van der Linden, 2003;Aggleton & Shaw, 1996;Parkin, Yeomans, & Bindschaedler, 1994). By this view, individuals can discriminate a target from a foil on a forced-choice test on the basis of relative familiarity.…”

Two recent studies reported that yes/no recognition can be more impaired by hippocampal lesions than forced-choice recognition when the targets and foils are highly similar. This finding has been taken in support of two fundamental proposals: (1) yes/no recognition tests depend more on recollection than do forced-choice tests; and (2) the hippocampus selectively supports the recollection process. Using the same stimulus materials as in the earlier studies, we tested five memory-impaired patients with circumscribed hippocampal lesions and 15 controls. As in the earlier studies, participants studied 12 pictures of objects and then took either a 12-item forced-choice test with four alternatives or a 60-item yes/no test. Patients were impaired on both tests but did more poorly on the yes/no test. However, a yes/no test based on 12 study items would conventionally involve only 24 test items (i.e., 12 study items and 12 foil items). When we scored only the first 24 test items, the patients performed identically on the yes/no and forced-choice tests. Examination of the data in blocks of 12 trials indicated that the scores of the patients declined as testing continued. We suggest that a yes/no test of 60 items is difficult relative to a 12-item forced-choice test due to the increased study-test delay and due to increased interference, not because of any fundamental difference between the yes/no and forced-choice formats. We conclude that hippocampal lesions impair yes/no and forced-choice recognition to the same extent.
