“…Our findings suggest that BrACs consistent with those of a social drinking episode for non-problem drinkers did not compromise psychomotor, set-shifting, or working memory abilities, as measured by three tasks, in this cohort. Null findings for the current study are in accord with previous acute alcohol investigations that assess a variety of cognitive functions (Dougherty et al, 2008;Leitz et al, 2009), including set-shifting (Gilbertson et al, 2009) and working memory (Tzambazis & Stough, 2000). Our results further suggest that low-dose alcohol might aid simple psychomotor ability.…”

ABSTRACT. Objective: The purpose of this study was to clarify inconsistent findings regarding the acute cognitive effects of subintoxicating alcohol doses (i.e., <80 mg/dl) by controlling for and evaluating variables that might modulate dose-related outcomes. Method: The current study examined the effects of sex/gender and alcohol concentration on select cognitive functions in 94 individuals (49 men) between 25 and 35 years of age. Participants were randomly assigned to one of three dose conditions: target peak breath alcohol concentration of 0 mg/dl (placebo), 40 mg/dl (low), or 65 mg/dl (moderate). After beverage consumption, they completed tasks assessing psychomotor, set-shifting, and working memory ability. Results: Analyses revealed no significant effect of dose for any cognitive domain. A trend-level effect of dose on psychomotor performance was observed, with the low-dose group performing somewhat better than the moderate-dose and placebo groups. No sex main effects or interactions were revealed. Conclusions: Consistent with our previous studies, these data suggest that low and moderate doses of alcohol may not compromise cognitive ability in non-problem drinkers under certain task conditions. Given the outcomes, sex differences cannot be meaningfully addressed. Future consideration of potentially influential variables and assessment of similarly well-defined cohorts might yield a clearer interpretation of alcohol's behavioral consequences. (J. Stud.

“…For example, in a clinical group with medial temporal sclerosis, Adda et al (2008) found that PM performance was impaired and that among those with left hemisphere lesions the degree of impairment was correlated with that in delayed (7 day) verbal recall on the Rey Auditory Verbal Learning Task (RAVLT). Leitz et al (2009) found that PM performance was significantly correlated with episodic memory recall following acute administration of alcohol. In another recent study utilising magnetoencephalography, Martin et al (2007) found that that the hippocampal region was activated longer during both retrospective and prospective memory tasks relative to a control condition.…”

“…The extent of the methamphetamine-related effect in PM was found to covary substantially with the degree of impairment on the Hayling task . In other research utilising the virtual week, Leitz et al (2009) demonstrated that performance was impaired following the acute administration of alcohol. However, in a subsequent study, the deficit was eliminated when individuals were instructed simulate the required actions at the time of encoding (by imaging the full sensory aspects of the context in which the action was to be completed; Paraskevaides et al, 2010).…”

Prospective memory functioning among ecstasy/polydrug users: evidence from the Cambridge Prospective Memory Test (CAMPROMPT)

et al. 2011

Rationale: Prospective memory (PM) deficits in recreational drug users have been documented in recent years. However the assessment of PM has largely been restricted to self report measures that fail to capture the distinction between event based and time based PM.The aim of the present study is to address this limitation.Objectives: Extending our previous research we augmented the range laboratory measures of PM by employing the CAMPROMPT test battery to investigate the impact of illicit drug use on prospective remembering in a sample of cannabis only, ecstasy/polydrug and non users of illicit drugs, separating event and time based PM performance. We also administered measures of executive function and retrospective memory in order to establish whether ecstasy/polydrug deficits in PM were mediated by group differences in these processes.Results: Ecstasy/polydrug users performed significantly worse on both event and time based prospective memory tasks in comparison to both cannabis only and non user groups.Furthermore, it was found that across the whole sample, better retrospective memory and executive functioning was associated with superior PM performance. Nevertheless, this association did not mediate the drug-related effects that were observed. Consistent with our previous study, recreational use of cocaine was linked to PM deficits.Conclusions: PM deficits have again been found among ecstasy/polydrug users which appear to be unrelated to group differences in executive function and retrospective memory.However, the possibility that these are attributable to cocaine use cannot be excluded.Prospective memory (PM) involves remembering to execute a particular behaviour at some future point in time which may be in the short or long term, for example remembering to turn off the lights when leaving a room or remembering to attend a meeting, meet a friend or pass on a message. Self report measures of this construct have been developed (e.g., Crawford et al., 2005;Hannon et al., 1995) and in previous research from our laboratory, Fisk and co-workers have demonstrated apparent impairments on these measures among ecstasy/polydrug users (Montgomery & Fisk, 2007) and cannabis only users (Fisk & Montgomery, 2008). Other researchers have also reported deficits on self report PM measures among users of illicit drugs (Heffernan et al., 2001a;2001b;Rodgers et al., 2001; and studies from our own laboratory and elsewhere have revealed deficits among illicit drug users in laboratory measures of PM (Hadjiefthyvoulou et al., in press;Rendell et al., 2007a;Rendell et al., 2009).Unsurprisingly, given their role in supporting memory functions in general, evidence suggests that PM is dependent on medial temporal-hippocampal processes. For example, in a clinical group with medial temporal sclerosis, Adda et al. (2008) found that PM performance was impaired and that among those with left hemisphere lesions the degree of impairment was correlated with that in delayed (7 day) verbal recall on the Rey Auditory Verbal Learning Task ...

“…Following this line of research, Addis, Wong, and Schacter (2008) have noted that there seems to be considerable overlap between PM and future thinking, and have drawn particular attention to the close relation between the processes involved in future thinking and those in the implementation of intentions. The authors point out that the implementation of an intention involves associating the intention with a specific future context, which closely resembles the episodic simulation involved in future thinking (Leitz, Morgan, Bisby, Rendell, & Curran, 2009;Schacter, Addis, & Buckner, 2008).…”

“…Similarly, Neroni, Gamboz, and Brandimonte (2014) reported positive effects of future thinking on PM in a student sample. Leitz et al (2009) and Paraskevaides et al (2010) both tested whether the provision of future thinking instructions would reduce the PM deficits associated with acute alcohol consumption in young adults. Results indicated that future thinking did significantly improve PM performance compared to a control condition.…”

Global impairment of prospective memory following acute alcohol

Abstract: These findings on an objective measure of PM suggest that 4-5 units of alcohol will compromise PM abilities in everyday life.
