Previous research showing everyday memory is impaired by heavy alcohol use may have underestimated the cognitive impairment of heavy users because drinkers consuming over the recommended limits for safe drinking have often been treated as a homogeneous group, often with a low threshold for inclusion. The current study investigated whether the reported linear relationship applies to participants consuming alcohol significantly above recommended limits. The everyday memory of 80 participants (43 men; modal age, 31-35 years) was investigated using the Prospective Memory Questionnaire. Participants also detailed their average weekly intake of alcohol and other substances. Current heavy users of alcohol (who consumed on average over 25 units per week) reported more memory problems than low (1-9 units per week) or medium users (10-25 units per week). Participants undergoing counselling for alcohol use reported more deficits than low or medium drinkers, but fewer than current heavy drinkers. Possible reasons for this were discussed. Strengths and limitations of subjective approaches to memory assessment were discussed as well as suggestions for future research. DOI 10.2466/PR0.106.3.905-917

Extensive research has identified individual differences associated with sex in a range of visual task performances, including susceptibility to visual illusions. The aim of this study was to identify the locus of sex differences within the context of the Poggendorf illusion. 79 women and 79 men participated within a mixed factorial design. Analyses indicated that sex differences were only present in the stimulus context with the full inducing element present. This finding replicates recent research and provides qualifying evidence as to the locus of the effect. The findings are discussed within the functional framework of perceptual processes involved in extrapolating 3-dimensional characteristics from 2-dimensional visual stimuli

Three experiments explored the effect of overt speech on children's use of 'inner speech' in short-term memory (STM). Experiments 1 and 2 compared recall of a series of pictured objects when 5- and 11-year-olds either labeled stimuli at presentation or remained silent. Use of inner speech was assessed by manipulating word length of the picture names (Experiment 1) or phonemic similarity (Experiment 2). Word length and phonemic similarity had greater effects in the older children and when pictures were labeled at presentation. These tendencies were such that 5-year-olds were sensitive to word length and phonemic similarity only with labeling. Experiment 3 compared labeling by the child with labeling by the experimenter in 5-years-olds. There were no significant differences with respect to overall performance or effects of word length and phonemic similarity. It is suggested that speaking or listening to speech activates an internal 'articulatory loop,' and that such activation is especially important when the child's ability to use inner speech in STM has not fully developed.

A study was conducted to compare the polydrug usage patterns reported by non-Ecstasy users, moderate Ecstasy users, and heavy ecstasy users. The increased use of Ecstasy is associated with more intensive patterns of Ecstasy/MDMA intake, and the greater use of illicit CNS stimulants and hallucinogens.

Prospective memory (PM) is memory for future events. PM is a developing area of research (e.g., Brandimonte, Einstein & McDaniel, 1996) with recent work linking personality types and their utilisation of PM (Goschke & Kuhl, 1996; Searleman, 1996). The present study compared 28 extraverts and 28 introverts on their short- and long-term prospective memory using the Prospective Memory Scale developed by Hannon, Adams, Harrington, Fries-Dias & Gibson (1995). The main finding was that extraverts reported significantly fewer errors on short- and long-term PM than introverts, and this difference could not be explained in terms of the number of strategies used to support prospective remembering. These findings are discussed in relation to differences between the personality types. [ABSTRACT FROM AUTHOR]

— Chronic alcohol abuse has a detrimental effect on retrospective memory. Less is known about its putative effects on everyday memory. This study looked at self-ratings of prospective memory (PM) (memory for future events). After controlling for other drug and strategy use, chronic heavy alcohol users showed global impairments in PM, when compared to matched controls. The underlying mechanisms are discussed.

A response by Richard Stephens to a letter to the editor about his article "Investigation of the "Hangover" Effects of an Acute Dose of Alcohol on Psychomotor Performance" in the 2008 issue is presented.

The consequences of alcohol consumption have risen high on health and social agendas in recent years. Although much work has focused on the physical problems associated with alcohol use, one theme that has emerged in alcohol research has been a focus on the effects of hangovers on functioning. This brief literature review specifically examines recent empirical investigations of the relationship between alcohol hangover and psychological performance and is tabled as an update to our earlier review of similar research (Stephens et al., 2008). A literature search generated 75 results on hangover and cognition (and synonyms) since the last published review. However, of these, only 4 met all inclusion criteria, such as establishing that BAL (Blood Alcohol Level) was zero at testing. Taking the findings of these newer studies with those that we reviewed previously, there appears to be real evidence of convergence of findings. There are now four rigorous laboratory studies, two less rigorous laboratory studies lacking placebo control and two rigorous naturalistic studies that indicate specific cognitive decrements in attention and memory during the hangover phase of alcohol consumption. Given this convergence, research agendas for increasing understanding of the cognitive effects of alcohol hangover should now switch from studies that routinely assess many cognitive functions to studies assessing the attention and memory deficits of hangover in greater detail.
