Implicit learning of social predictions

Humans exchange a range of nonverbal social signals in every interaction. It is an open question whether people use these signals, consciously or unconsciously, to guide social behavior. This experiment directly tested whether participants could learn to predict another person’s behavior using nonverbal cues in a single interaction, and whether explicit knowledge of the cue-outcome relationship was necessary for successful prediction. Participants played a computerized game of rock-paper-scissors against an avatar they believed was another participant. Sometimes the avatar generated a predictive facial cue before the play. On these trials, participants’ win-frequency increased over time, even if they did not acquire explicit knowledge of the predictive cue. The degree to which participants could predict the avatar (wins on cued trials) related to their self-reported liking of the avatar. These findings demonstrate the importance of implicit associative learning mechanisms in guiding social behavior on a moment-to-moment basis during interaction.     

Efficacy of Treating Sexual Trauma in a Substance Abuse Residential Program for Women

This is a program evaluation of treating sexual trauma in a residential substance abuse treatment program for women. Residents who were seeking treatment for their substance abuse disorder (SUD), also had a history of both childhood and adult sexual trauma. Given the literature supporting concurrent trauma-SUD treatment, the Warrior Renew (WR) protocol (Katz, Warrior Renew: Healing from military sexual trauma, Springer, New York, 2014) was added to the curriculum of Alcoholics Anonymous 12-step groups, relapse prevention, and substance abuse education classes. The WR manual consists of coping skills to address sleep and anxiety, and cognitive/experiential restructuring to address anger/resentments due to injustice, betrayal, and self-blame. It also addresses interpersonal factors such as relationship patterns and healthy interpersonal skills. This evaluation was conducted as part of routine clinical care in a naturalistic setting. Nineteen residents graduated the program and opted to complete pre-and post-treatment assessments. Findings revealed significant decreases in symptoms of anxiety, depression, posttraumatic negative thinking, and PTSD, and significant increases in positive factors of optimism and self-esteem-- all with large effect sizes. In addition, 95% of the sample had a reliable change at the 95% confidence interval. Resident’s feedback to staff reflected strong positive endorsement of the WR program. Results suggest WR is a promising effective treatment for women who have had sexual trauma in a substance abuse residential treatment program.
