Dataset Description (Abstract): Episodes of extreme alcohol binge-drinking can result in memory loss, transient anterograde amnesic experiences known as memory blackouts (MBO). The current study investigates whether falsely remembering details or events is more likely for those who frequently experience blackouts (at least 9 in the preceding 12-months) compared to controls who had never experienced an MBO. Participants completed a DRM (Deese, Roediger, & McDermott paradigm; Roediger & McDermott (1995)) recognition memory task, with a follow-up remember/know/guess judgement, before-alcohol and after-alcohol, while the MBO group additionally completed the task within 20-hours of a blackout, but when sober again. Both groups displayed reduced ability to discriminate between old and new words, and a more conservative response strategy, after-alcohol, which remained for MBO participants after-MBO. Lure words elicited more false alarms than unrelated words, yet the overall frequency of false alarms dropped after-alcohol. Interestingly, the MBO group recorded more ‘know’ than ‘remember’ responses compared to controls, suggesting a greater reliance on the process of familiarity than recollection. In contrast to our hypothesis, uncertainty in memory led to more caution in this experimental context. Future work should focus on whether naturalistic studies of alcohol-induced memory blackouts could identify increased false memory acceptance rates.
Dataset Description (TOC): Dataset compiled by Judith Jackson and Benjamin Dering: judith.jackson1@stir.ac.uk and b.r.dering@stir.ac.uk The Dataset incorporates all behavioural data and statistical model outputs for the study reported in Did that happen, or am I just making it up? Investigating false memories after alcohol-induced memory blackouts in sober young adults Experiment name: DRM File: DRM_Data_Workbook.xlsx Tab 1: DRM_DPrime_Between Description: Includes dPrime and C calculations, per participant, per alcohol condition. Each score is the mean of three blocks per condition, and is presented based on the origin of the study block. For example, \'91dFree\'92 means the mean dPrime score of words recognised which were earlier presented for study as part of a free recall manipulation. Therefore, \'91cSerial\'92 is the mean C score for words presented for study in a serial recall task. Control and Experimental (MBO) group participant scores for before alcohol, and after alcohol, are included. Tab 2: DRM_DPrime_Within Description: As previous tab, but lists the experimental (MBO) group scores only in all three conditions - before alcohol, after alcohol, after MBO. Tab 3: RKG_Between Description: Shows mean accuracy (%) per participant, and also separated by follow-up RKG judgement. Further, included are total false alarms (%), FAs by related or unrelated lure word, and additionally split by RKG judgement. Tab 4: RKG_Within Description: As previous tab, but within the experimental group across 3 conditions (before alcohol, after alcohol, after MBO). Tab 5: DRM_Sleep Description: Number of reported minutes slept per participant, with the corresponding difference between dPrime and False Alarms (TFA_T1T3) at before alcohol and after MBO. Tab 6: Randomise Participants Description: Before alcohol and after MBO results, resampled by randomising 2000 times in order to create test distributions. Tab 7: Individuals_DPrime Description: Actual mean differences between before alcohol and after blackout compared to z-score differences from test distributions in order to highlight MBO effects in individual participants. Tab 8: Summary_Stats_Between Description: Output summaries for all between group comparisons, from R statistical software. Details linear model outputs, by addition of predictor. Best fitting model summary is then recorded, with corresponding r numbers and/or Bonferroni corrected effect sizes. Tab 9: Summary_Stats_Within Description: As previous tab, for all within experimental (MBO) group comparisons.
