“…Everyday memory: The Everyday Memory Questionnaire (EMQ, Cornish, 2000;Sunderland et al 1983) is an established self-report measure of memory lapses in everyday activities. It consists of 27 statements, and in each case, participants respond on a 9-point scale ranging from "not at all in the last 6 months" to "more than once a day".…”

“…The shift-cost was the ratio between the average reaction times of the third block and the averages of the first two blocks. Measures included the number of correct responses in trial 1 (a measure of initial recall), forgetting, and the number of trials required to learn all associations.Everyday memory: The Everyday Memory Questionnaire (EMQ, Cornish, 2000;Sunderland et al 1983) is an established self-report measure of memory lapses in everyday activities.

“…For example cannabis users might be more likely to forget the location of familiar objects around the house, forget to take essential objects when leaving the home or office, fail to recognise acquaintances, or forget important events that occurred the previous day, etc. These are all capacities that are assessed in established measures of everyday memory (Sunderland et al, 1983) or cognitive failures (Broadbent et al, 1982). An additional aspect of memory that is of relevance beyond laboratory contexts is prospective memory.…”

Measures of executive component processes, associative learning, everyday memory, prospective memory, and cognitive failures were administered. Relative to nonusers, cannabis users were found to be impaired in several aspects of real world memory functioning. No other group differences were apparent. The absence of cannabis related deficits in those executive component processes and aspects of learning that are believed to support real world memory processes is surprising given that cannabis related deficits were obtained in real world memory. The present results are discussed within the context of neuroimaging evidence which suggests that cannabis users may exhibit different patterns of neural activation when performing executive tasks while not always exhibiting deficits on these tasks.Keywords: Cannabis, executive processes, prospective memory, cognitive failures 3 The focus of the present paper is real world memory functioning in abstinent cannabis users. More specifically we intend to explore the basis of cannabis-related deficits in prospective memory, everyday memory, and cognitive failures, and the extent to which these impairments are underpinned by deficits in pre-frontal executive processes. Given that cannabis is clearly the most popular illicit drug in North America, Europe and in other parts of the world (Andersson et al, 2005) it is of considerable importance to investigate whether consumption of the drug is associated with cognitive deficits.Cannabis contains a number of chemical compounds collectively known as cannabinoids. The psychoactive properties of cannabis are mainly due to one of these cannabinoids, Δ 9 tetrahydrocannabinol, (THC). Animal studies have revealed that chronic administration of THC causes hippocampal damage and impairs maze learning in rats ...

“…Such tests may not reflect the memory demands of daily living, which require coordination of multiple cognitive processes such as planning and vigilance, and therefore may not have ecological relevance [18,19]. Recall of retrospective events has been distinguished from prospective memory (remembering intended actions, or 'remembering to remember'), and tests of prospective memory may have greater ecological validity [20].…”

The effects of acute hypoglycaemia on memory acquisition and recall and prospective memory in type 1 diabetes

et al. 2006

Aims/hypothesis Global memory performance is impaired during acute hypoglycaemia. This study assessed whether moderate hypoglycaemia disrupts learning and recall in isolation, and utilised a novel test of prospective memory which may better reflect the role of memory in daily life than conventional tests. Subjects and methods Thirty-six subjects with type 1 diabetes participated, 20 with normal hypoglycaemia awareness (NHA) and 16 with impaired hypoglycaemia awareness (IHA). Each underwent a hypoglycaemic clamp with target blood glucose 2.5 mmol/l. Prior to hypoglycaemia, subjects attempted to memorise instructions for a prospective memory task, and recall was assessed during hypoglycaemia. Subjects then completed the learning and immediate recall stages of three conventional memory tasks (word recall, story recall, visual recall) during hypoglycaemia. Euglycaemia was restored and delayed memory for the conventional tasks was tested. The same procedures were completed in euglycaemic control studies (blood glucose 4.5 mmol/l). Results Hypoglycaemia impaired performance significantly on the prospective memory task (p=0.004). Hypoglycaemia also significantly impaired both immediate and delayed recall for the word and story recall tasks (p<0.01 in each case). There was no significant deterioration of performance on the visual memory task. The effect of hypoglycaemia did not differ significantly between subjects with NHA and IHA. Conclusions/interpretation Impaired performance on the prospective memory task during hypoglycaemia demonstrates that recall is disrupted by hypoglycaemia. Impaired performance on the conventional memory tasks demonstrates that learning is also disrupted by hypoglycaemia. Results of the prospective memory task support the relevance of these findings to the everyday lives of people with diabetes.

“…This calls into question the validity of self-report data on cognitive function generated from quality of life (QL) measures in common use in oncology, e.g. the EORTC QLQ-C30 (Aaronson et al, 1993) (Sunderland et al, 1983). The Rivermead Behavioural Memory Test (RBMT) (Wilson et al, 1991) differs from the majority of previously published memory tests in sampling behaviours characteristic of everyday life.…”

Summary Cognitive function items are increasingly included in quality of life measures, and complaints of concentration and memory difficulties are often reported by cancer patients. The aim of this study was to examine the factors influencing patients' level of complaint by comparing subjective reports with objective test performance of a sample of adult lymphoma patients, disease-free and > 6 months after treatment. There was no significant difference between complainers and non-complainers in sociodemographic or clinical characteristics or in their performance on standard neuropsychometric tests of concentration and memory. Those reporting concentration and memory difficulties had significantly higher scores on measures of anxiety, depression and fatigue. This calls into question the validity of including cognitive function items in self-report quality of life measures. Patients who report concentration and memory difficulties should be screened for clinically significant and potentially remediable mood disorder. Objective testing remains the method of choice for assessing higher mental function.
