The purpose of the present study was to determine the extent to which familiarity can support associative recognition memory as a function of whether the associations are within- or between-domain. Standard recognition and familiarity only performance were compared in different participants, using a new adaptation of the remember/know procedure. The results indicated that within-domain (face face) associative recognition was mainly supported by familiarity. In contrast, familiarity provided relatively poor support to between-domain (face name) associative recognition for which optimal performance required a major recollection contribution. These findings suggest that familiarity can support associative recognition memory, particularly for within-domain associations, and contrast with the widely held view that associative recognition depends largely on recollection.

There is currently a debate regarding the status of recall and recognition memory in amnesic patients with focal hippocampal damage. Proportionate deficits of recall and recognition memory have been observed in some patients with selective hippocampal damage. In addition, these patients showed an impairment of both the recollection and familiarity aspects of recognition memory. In contrast, other amnesic patients with selective hippocampal lesions demonstrated relatively preserved recognition memory, despite severely impaired recall abilities. In some of them, familiarity processes were found to be intact. The resolution of this controversy has important implications for theories of episodic memory. In the present study, we examined the recall and recognition performance of an amnesic patient, MR, who suffered from bilateral hippocampal damage and temporoparietal cortical atrophy following carbon monoxide poisoning. Verbal and nonverbal recall and recognition memory were measured by tasks matched for difficulty. On these tasks, MR’s recall performance was more severely impaired than his recognition memory. In addition, MR’s recognition performance was normal on most of the tasks. In order to determine on which processes MR based his recognition decisions, we administered to the patient and to matched controls the process dissociation procedure. This evaluates the contribution of recollection and familiarity within a recognition task. The results indicated that, in this patient, familiarity was preserved, but recollection was impaired. This study thus supports the idea that amnesic patients with hippocampal damage can show preserved familiarity-based recognition memory, despite poor recall and recollection. [less ▲]

Some patients with relatively selective hippocampal damage have shown proportionate recall and recognition deficits. Moreover, familiarity as well as recollection have been found to be impaired in some of these patients. In contrast, other patients with apparently similar damage presented with relatively preserved recognition despite having severely impaired recall, and some of these patients have been shown to have preserved familiarity. We report here the case of an amnesic patient who suffered bilateral hippocampal damage and temporoparietal atrophy after carbon monoxide poisoning. On tests matched for difficulty, his recall performance was more severely impaired than his recognition memory, for verbal as well as for visual materials. Moreover, he performed within the range of healthy matched subjects on nine recognition tests out of ten. In a task using the process dissociation procedure, the patient’s familiarity was preserved although his recollection was impaired. These findings indicate that recall and recognition memory can be dissociated in amnesic patients with hippocampal lesions even when temporoparietal cortical atrophy is also present. [less ▲]

The aim of this experiment is to examine how recollection and familiarity change over time and whether there is a qualitative difference between familiar items that were previously recollected and items that have always been familiar. It might be that, when an item is initially recollected and becomes just familiar after a delay, this form of familiarity is actually a weak and partial recollection, qualitatively different from mere familiarity. To address this issue, a task have been developed in which, at study, participants encoded two series of 100 pictures representing scenes under respectively shallow and deep encoding conditions. Memory for these pictures was tested by means of a yes-no recognition test. Recognised items were classified as recollected or as familiar. Half of the pictures from each encoding condition were tested after 10 minutes and the other half were tested after 2 days. The results indicated that recollection decreased after 2 days while familiarity increased (deep encoding condition) or did not change (shallow encoding condition). This suggests that, among the items judged as familiar after 2 days, some items would have been recollected after 10 minutes and some were initially already familiar. Because deep encoding produced a higher proportion of recollection at the 10-minute interval, the proportion of recollection-changed-into-familiarity responses should be greater in this condition than in the shallow encoding condition. Whether there is a qualitative difference between these responses and pure familiarity responses should be explored in a fMRI experiment. [less ▲]
