RESUMEN
This study investigated the ability of three adverse childhood experience (ACE) types (household dysfunction, emotional/physical abuse, and sexual abuse) to predict current depression among adults. We also determined the contribution of ACEs to current depression after controlling for covariates and chronic illnesses. Respondents to the 2010 Behavioral Risk Factor Surveillance System (n = 20,345) were divided into depressed and not depressed groups based on Patient Health Questionnaire-8 (PHQ-8) scores. Binary logistic regression determined the ability of ACE exposure to predict depression while controlling for effects of covariates and number of chronic illnesses. Hierarchical multiple linear regression determined the association of ACEs on depression scores after accounting for the covariate set and chronic illnesses. Sexual Abuse had the single strongest association with current depression of any ACE exposure. Exposure to three ACE types has the greatest association with current depression. ACEs accounted for about 7% of the variance in depression scores.

The present study investigated the effect of encoding duration on implicit and explicit eyewitness memory. Participants (Nâ¯=â¯227) viewed a mock crime (brief, 15-s vs. long, 30-s vs. irrelevant/control) and were then tested with both implicit and explicit memory prompts or with explicit memory prompts only. Brief-encoding participants revealed more critical details implicitly than long-encoding or control participants. Further, the number and percentage of accurate details recalled explicitly were higher for long-encoding than for brief-encoding participants. Implicit testing prior to explicit recall-as compared to completing a filler task-was detrimental to free recall performance. Interestingly, brief-encoding participants were significantly more likely to remember critical details implicitly but not explicitly than long-encoding participants. This is the first study to investigate implicit eyewitness memory for a multimodal mock crime. Findings are theoretically consistent with prior research on cognition while expanding upon the extant eyewitness memory and investigative interviewing literature.

Many real-world eyewitnesses are under the influence of alcohol either at the time of the crime, the interview, or both. Only recently has empirical research begun to examine the effects of alcohol on witness memory, yielding mixed results. The present study tested the importance of state-dependent memory in the context of alcohol's effects on encoding versus retrieval of a witnessed event, while simultaneously informing real-world investigative practices: Should witnesses sober up before an interview? Participants (N = 249) were randomized to a control, placebo, or alcohol condition at encoding and to either an immediate retrieval condition (in the same state) or a 1-week delay control, placebo, or alcohol retrieval condition. They recalled a witnessed mock crime using open ended and cued recall formats. After a delay, witnesses intoxicated at both encoding and retrieval provided less accurate information than witnesses in sober or placebo groups at both times. There was no advantage of state-dependent memory but intoxicated witnesses were best when recalling immediately compared to 1 week later (sober, placebo, or reintoxicated). Findings have direct implications for the timing of intoxicated witnesses' interviews such that moderately intoxicated witnesses may not benefit from a sobering delay but rather, should be interviewed immediately.

According to law enforcement, many witnesses are intoxicated either at the time of the crime, the interview, or both (Evans et al., Public Policy Law 15(3):194-221, 2009). However, no study to date has examined whether intoxicated witnesses' recall is different from sober witnesses' and whether they are more vulnerable to misinformation using an ecologically valid experimental design. Intoxicated, placebo, and sober witnesses observed a live, staged theft, overheard subsequent misinformation about the theft, and took part in an investigative interview. Participants generally believed they witnessed a real crime and experienced a real interview. Intoxicated witnesses were not different from placebo or sober witnesses in the number of accurate details, inaccurate details, or "don't know" answers reported. All the participants demonstrated a misinformation effect, but there were no differences between intoxication levels: Intoxicated participants were not more susceptible to misinformation than sober or placebo participants. Results are discussed in the light of their theoretical and applied relevance.

Alcohol typically has a detrimental impact on memory across a variety of encoding and retrieval conditions (e.g., Mintzer, 2007; Ray & Bates, 2006). No research has addressed alcohol's effect on memory for lengthy and interactive events and little has tested alcohol's effect on free recall. In this study 94 participants were randomly assigned to alcohol, placebo, or control groups and consumed drinks in a bar-lab setting while interacting with a "bartender". Immediately afterwards all participants freely recalled the bar interaction. Consistent with alcohol myopia theory, intoxicated participants only differed from placebo and control groups when recalling peripheral information. Expanding on the original hypervigilance hypothesis, placebo participants showed more conservative reporting behaviour than the alcohol or control groups by providing more uncertain and "don't know" responses. Thus, alcohol intoxication had confined effects on memory for events, supporting and extending current theories.
