Memory failures reported by obsessive-compulsive (OC) checkers often seem to be errors of "reality-monitoring", or misremembering whether one performed or imagined performing an action. To examine these memory processes in the context in which such errors are said to occur, an in-home reality-monitoring experiment involving bothersome and non-bothersome actions was conducted with 21 OC checkers...

Eyewitness memory is widely believed to be unreliable because (1) high-confidence eyewitness misidentifications played a role in over 70% of the now more than 300 DNA exonerations of wrongfully convicted men and women, (2) forensically-relevant laboratory studies have often reported a weak relationship between eyewitness confidence and accuracy, and (3) memory is sufficiently malleable that, no...

Numerous functional neuroimaging studies have observed lateral parietal lobe activation during memory tasks: a surprise to clinicians who have traditionally associated the parietal lobe with spatial attention rather than memory. Recent neuropsychological studies examining episodic recollection after parietal lobe lesions have reported differing results. Performance was preserved in unilateral l...

The present study investigated episodic memory functioning in: (1) obsessive compulsive disorder (OCD) patients with primarily checking symptoms (i.e. checkers); (2) OCD patients without checking symptoms (i.e. non-checkers); and (3) non-clinical control participants. On a measure of recall, all groups were statistically equivalent with respect to the proportion of words correctly recalled. Usi...

We explored what kind of information is acquired when amnesic patients are able to exhibit significant retention on tests of cued recall and recognition memory. Amnesic patients and control subjects attempted to learn sets of sentences. Memory for the last word in each sentence was tested after 1 hr in the case of the amnesic patients, or after 1 to 2 weeks in the case of (delayed) control subj...
