In an assessment of the Alcohol Myopia Theory, this research investigated the effects of alcohol on an eyewitness's recall of high and low salience details. In Study 1, participants watched a staged videoed theft in a laboratory whilst either sober (control or placebo), above (MBAC = 0.09%) or below (MBAC = 0.06%) the UK drink-drive limit. A week later a free recall and recognition test were completed. These levels of intoxication were not found to reduce the accuracy of an individual's recall using either recall task. In Study 2, while on a night out participants watched the videoed theft with either high (MBAC = 0.14%) or low (MBAC = 0.05%) levels of intoxication. A week later the free recall and recognition test were attempted. High levels of intoxication were seen to impair recall when memory was assessed through free recall but not with the recognition test. Neither study however found the narrowing of attention predicted by Alcohol Myopia Theory using either the recognition test or free recall, although poor recall for peripheral details in all groups may have contributed to this result. The findings of this research are discussed in terms of their real world value and the path of future research.Intoxicated witness recall 2

This large, international dataset contains survey responses from N = 12,570 students from 100 universities in 35 countries, collected in 21 languages. We measured anxieties (statistics, mathematics, test, trait, social interaction, performance, creativity, intolerance of uncertainty, and fear of negative evaluation), self-efficacy, persistence, and the cognitive reflection test, and collected demographics, previous mathematics grades, self-reported and official statistics grades, and statistics module details. Data reuse potential is broad, including testing links between anxieties and statistics/mathematics education factors, and examining instruments’ psychometric properties across different languages and contexts. Data and metadata are stored on the Open Science Framework website (https://osf.io/mhg94/).
