Individual Differences In Social Play Behaviour Predict Alcohol Intake And Control Over Alcohol Seeking In Rats, Heidi M. B. Lesscher, E. J. Marijke Achterberg, Stephen M. Siviy, Louk J. M. J. Vanderschuren

Psychology Faculty Publications

Rationale

Social play behaviour is a rewarding social activity displayed by young mammals, thought to be important for the development of brain and behaviour. Indeed, disruptions of social play behaviour in rodents have been associated with cognitive deficits and augmented sensitivity to self-administration of substances of abuse, including alcohol, later in life. However, the relation between social development and loss of control over substance use, a key characteristic of substance use disorders including alcohol use disorder (AUD), has not been investigated. Moreover, it remains unknown how inherent differences in playfulness relate to differences in the sensitivity to substance use and …

#Bopo: The Effect Of Body Positive Social Media Content On Women’S Mood And Self-Compassion, Hope R. Rutter, Kaley M. Michael, Brittany J. Repak, Cindy J. Campoverde-Reinoso, Thao Hoang, Kathy R. Berenson

Student Publications

Body positivity is a trending movement that promotes appreciation of one’s body, including acceptance of one’s appearance and perceived flaws. In two experiments, we compared the effects of body-positive social media content relative to idealized body content and neutral control content on young women’s psychological states. In study 1, participants were randomly assigned to view Instagram posts involving fitspiration photos, body positive photos, body positive quotes, or travel landscape photos. In study 2, participants were randomly assigned to view Instagram posts involving selfies of the same individuals’ faces with or without makeup. As predicted, viewing body positive content (body positive …

I Saw That: Being Observed Reduces Race-Based Shoot Decisions, Sarah S. Kramer, Kaitlin M. Lewin, Allison S. Romano, Brian P. Meier

Student Publications

The shooter bias effect reveals that individuals are quicker to “shoot” armed Black (vs. White) men and slower to “not shoot” unarmed Black (vs. White) men in a computer task. In three studies (N = 386), we examined whether being observed would reduce this effect because of social desirability concerns. Participants completed a “shooting” task with or without a camera/live observer supposedly recording behavior. Cameras were strapped to participants’ heads (Studies 1a/1b) and pointed at them (Study 1b). In Study 2, a researcher observed participants complete the task while “filming” them with a smartphone. We replicated the shooter bias, …

Naturally Better? A Review Of The Natural‐Is‐Better Bias, Brian P. Meier, Amanda J. Dillard, Courtney M. Lappas

Psychology Faculty Publications

People are frequently exposed to products and services that are labeled natural (e.g., Nature Made Vitamins or GoJo Natural Orange Hand Cleaner). The frequency with which this label is used suggests that it delivers an advantage in marketing and sales. Our review examines the preference for and perception of naturalness and reveals that people have a bias for items described as natural in many domains including foods, medicine, beauty products, cigarettes, and lighting. These preferences abound even when the natural item is identical or not objectively better than the non‐natural or synthetic item. We believe this bias may be driven …

A Behavioral Confirmation And Reduction Of The Natural Versus Synthetic Drug Bias, Brian P. Meier, Amanda J. Dillard, Eric S. Osorio, Courtney M. Lappas

Psychology Faculty Publications

Research reveals a biased preference for natural versus synthetic drugs; however, this research is based upon self-report and has not examined ways to reduce the bias. We examined these issues in five studies involving 1,125 participants. In a Pilot Study (N = 110), participants rated the term natural to be more positive than the term synthetic, which reveals a default natural-is-better belief. In Studies 1 (N = 109) and 2 (N = 100), after a supposed personality study, participants were offered a thank you “gift” of a natural or synthetic pain reliever. Approximately 86% (Study 1) and 93% (Study 2) …

The Interaction Between Perfectionism And Rumination Predicting State Self-Compassion, Caitlin A. Sharp

Student Publications

Recent research has revealed self-compassion to be associated with many aspects of mental wellness. The present study investigates the relationship between perfectionism and rumination in predicting state self-compassion separately for both conscientious and self-evaluative forms of perfectionism. We hypothesized that perfectionism would interact with rumination in predicting state self-compassion such that there would be a negative association between occurrence of rumination and state-self compassion that would be more prominent in those with lower levels of perfectionism in regards to self-evaluative, but not conscientious perfectionism. To test these predictions, participants filled out a perfectionism inventory and completed a four minute ruminative …

Impulsivity, Rejection Sensitivity, And Reactions To Stressors In Borderline Personality Disorder, Kathy R. Berenson, Wesley Ellen Gregory, Erin Glaser, Aliza Romirowsky, Eshkol Rafaeli, Xiao Yang, Geraldine Downey

Psychology Faculty Publications

This research investigated baseline impulsivity, rejection sensitivity, and reactions to stressors in individuals with borderline personality disorder compared to healthy individuals and those with avoidant personality disorder . The borderline group showed greater impulsivity than the avoidant and healthy groups both in a delay-discounting task with real monetary rewards and in self-reported reactions to stressors; moreover, these findings could not be explained by co-occurring substance use disorders. Distress reactions to stressors were equally elevated in both personality disorder groups (relative to the healthy group). The borderline and avoidant groups also reported more maladaptive reactions to a stressor of an interpersonal …

The Peacock Effect: The Influence Of The Opposite Sex On Aggressive Behavior, Kira J. Mason

Celebration

Most widely-accepted models for aggression do not explicitly address an important variable that roots in evolutionary psychology: the presence of a potential mate. The current research investigates whether the presence of an attractive or unattractive member of the opposite sex influences hypothetical aggression. Participants (N = 1035) imagined themselves in front of an attractive or non-attractive member of the opposite sex (accompanied by pictures of corresponding attractiveness levels), and indicate their aggressive intentions after a provocation, or not. Results from the 2(sex) x 2(attractiveness) ANOVA showed that males viewing an image of an attractive female aggressed more when provoked than …
