Recent research involving consent, alcohol intoxication, and memory: Implications for expert testimony in sexual...

When adjudicating sexual assault cases, it is imperative that attorneys are educated on the incident characteristics relevant to their case and that expert witnesses are prepared to consult and/or testify regarding relevant science. Most reported sexual assault cases occur when at least one of the relevant parties has consumed alcohol, which has neurochemical, behavioral, psychological, and cognitive effects that are important to consider relative to the facts of the case. Nearly a decade ago, Connell (2015) provided an overview of research relevant to an expert witness's role in these types of cases. In the current review, we extend Connell's (2015) work by examining recent research examining alcohol intoxication and memory. We also expand our review to include current research examining alcohol use in voluntary sexual behavior and issues of sexual consent, as it provides both a legal and conceptual framework for the discussion of sexual assault crimes. The goal of the review is to highlight implications of the scientific research on legal decision-making and potential expert testimony.
