Peer Effects on Risky Behaviors: New Evidence from College Roommate Assignments
Daniel Eisenberg, Ezra Golberstein & Janis Whitlock
Journal of Health Economics, January 2014, Pages 126–138
Abstract:
Social scientists continue to devote considerable attention to spillover effects for risky behaviors because of the important policy implications and the persistent challenges in identifying unbiased causal effects. We use the natural experiment of assigned college roommates to estimate peer effects for several measures of health risks: binge drinking, smoking, illicit drug use, gambling, having multiple sex partners, suicidal ideation, and non-suicidal self-injury. We find significant peer effects for binge drinking but little evidence of effects for other outcomes, although there is tentative evidence that peer effects for smoking may be positive among men and negative among women. In contrast to prior research, the peer effects for binge drinking are significant for all subgroups defined by sex and prior drinking status. We also find that pre-existing risky behaviors predict the closeness of friendships, which underscores the significance of addressing selection biases in studies of peer effects.

Self-Regulating the Effortful “Social Dos”
Kassandra Cortes et al.
Journal of Personality and Social Psychology, forthcoming
Abstract:
In the current research, we explored differences in the self-regulation of the personal dos (i.e., engaging in active and effortful behaviors that benefit the self) and in the self-regulation of the social dos (engaging in those same effortful behaviors to benefit someone else). In 6 studies, we examined whether the same trait self-control abilities that predict task persistence on personal dos would also predict task persistence on social dos. That is, would the same behavior, such as persisting through a tedious and attentionally demanding task, show different associations with trait self-control when it is framed as benefitting the self versus someone else? In Studies 1–3, we directly compared the personal and social dos and found that trait self-control predicted self-reported and behavioral personal dos but not social dos, even when the behaviors were identical and when the incentives were matched. Instead, trait agreeableness — a trait linked to successful self-regulation within the social domain — predicted the social dos. Trait self-control did not predict the social dos even when task difficulty increased (Study 4), but it did predict the social don’ts, consistent with past research (Studies 5–6). The current studies provide support for the importance of distinguishing different domains of self-regulated behaviors and suggest that social dos can be successfully performed through routes other than traditional self-control abilities.

‘Let me dream on!’ Anticipatory emotions and preference for timing in lotteries
Martin Kocher, Michal Krawczyk & Frans van Winden
Journal of Economic Behavior & Organization, forthcoming
Abstract:
We analyze one of the explanations why people participate in lotteries. Our hypothesis stipulates that part of the value that a unit of money buys in lotteries is consumed before the actual resolution in the form of emotions such as hope. In other words, a person holding a lottery ticket may prefer a delayed resolution of risk due to positive anticipatory emotions. This conjecture is tested in an experiment with real lottery tickets. We show that our theoretical considerations may contribute to explaining empirical puzzles associated with lottery participation, timing of resolution and the spreading of lots over drawings. More specifically, we find that a substantial minority of participants prefer delayed resolution, that anticipated thrill is the main variable explaining this choice, and that emotions actually experienced during the waiting period are indeed predominantly positive and correlated with predictions. Finally, we find that a great majority prefers to ‘spread’ chances, that is, to obtain one ticket for each of two drawings rather than two for the same drawing.

In the Spotlight: Brightness Increases Self-Awareness and Reflective Self-Regulation
Anna Steidle & Lioba Werth
Journal of Environmental Psychology, forthcoming
Abstract:
Impulse and reflection jointly drive people’s behavior. However, the impact of the physical environment, especially light and brightness, on reflective and impulsive behavior and the underlying processes have not been understood. We expected that light and brightness would increase self-awareness and, in turn, lead to a reflective and controlled self-regulation. Five studies confirmed our assumptions. Particularly, participants in a brightly lit room reported a higher public self-awareness than those in a dim room. Moreover, brightness triggers more controlled and reflective forms of self-regulation independent of whether lighting conditions (Study 2) or priming methods (Study 3) were used to manipulate brightness. Finally, two additional studies revealed that brightness facilitates the suppression of desires and socially undesirable impulses which signals high self-control. Overall, these results contribute to the understanding of automatic effects of light and brightness and effortless self-control. Limitations as well as practical implications for lighting design in therapeutical settings and retail spaces and are discussed.

Shared Losses Reduce Sensitivity to Risk: A Laboratory Study of Moral Hazard
Michael Bixter & Christian Luhmann
Journal of Economic Psychology, forthcoming
Abstract:
Moral hazards are said to occur when one party makes decisions that have potential negative consequences that will either fully or partially be experienced by another party. The present experiment sought to explore moral hazard in a laboratory setting. Participants made choices between certain and risky rewards. On some trials, participants would bear the full brunt of a loss if the risky reward was chosen and lost. On other trials, participants believed losses would be shared with another party creating the opportunity for moral hazard. Our design allowed us to measure whether the presence of a moral hazard influenced participants’ choice behavior and to quantify the magnitude of this influence. Results suggested that participants were more tolerant of risk when they believed losses would be shared with another party compared to choices when all of the loss would be experienced personally. More importantly, concern for the third party losses appeared to exert no influence on choices whatsoever. These results were found when the third party was anonymous (Experiment 1) but also when they met the third party face-to-face (Experiment 2). The relationship between the current results and real-life moral hazards, as well as possible future research directions, is discussed.

The Bright Side of Impulse: Depletion Heightens Self-Protective Behavior in the Face of Danger
Monika Lisjak & Angela Lee
Journal of Consumer Research, forthcoming
Abstract:
Ample research suggests that after engaging in a self-regulatory task, people become depleted and are more likely to behave in maladaptive ways by yielding to their impulses. However, yielding to impulses may not always be maladaptive. This research suggests that when people are depleted, they feel more vulnerable when encountering potential danger, and are therefore more likely to engage in self-protection. Across five studies, depleted (vs. non-depleted) participants reported being less likely to engage in risky behaviors such as having unprotected sex (study 1) and more likely to engage in risk-reduction behaviors such as getting tested for kidney diseases and chlamydia (studies 2 and 3). Depleted individuals also preferred products that emphasize safety (studies 4 and 5). Perceived vulnerability is shown to mediate the effect of depletion on self-protective behavior (studies 1 and 2). Together, these findings show that yielding to impulses may sometime help attain beneficial and healthful goals.

Abstract:
The purpose of the present study was to evaluate an adapted web-based multi-component personalized feedback intervention to reduce college student alcohol use and risky sexual behavior during Spring Break. This is one of the first interventions focused on Spring Break alcohol use and related sexual behavior. Personalized feedback intervention components addressed intentions, expected consequences, norms, motivations, protective behavioral strategies, and pacts with friends. Participants were college students (N = 263; 55% women) between the ages of 18 and 21 who planned to go on a Spring Break trip with their friends. Effects were not significant in reducing alcohol use or sexual behavior during Spring Break or some of the proposed intervention mechanisms. However, consistent results showed that the intervention succeeded in reducing perceived social norms for Spring Break drinking and sexual behavior. Findings suggest that changing norms alone is not sufficient for changing risk behavior during this event and alternative strategies are needed to impact other putative mediators.

Beyond Mars and Venus: Understanding Gender Differences in Financial Risk Tolerance
Philip Lemaster & JoNell Strough
Journal of Economic Psychology, forthcoming
Abstract:
Research indicates that men are more risk tolerant and make riskier financial decisions than women. To explain this, researchers have favored “essentialist” explanations that attribute differences to core biological mechanisms and have tended to neglect psychological mechanisms that reflect the influence of culture and socialization. To better understand gender differences in risk tolerance, we investigated the relative effects of multiple psychological dimensions of gender, including gender identification (i.e., identifying as one’s biological sex and viewing it as a positive part of the self), gender typicality (i.e., feeling like a typical member of one’s biological sex), and gender-stereotyped personality traits and social roles. We also measured 2D:4D digit ratios as an indicator of prenatal testosterone exposure. Stereotypically masculine or instrumental personality traits (e.g., strong, acts as a leader) were associated with more risk tolerance in both men and women but were relatively more important for understanding men’s risk tolerance. Stereotypically feminine or communal personality traits were associated with less risk tolerance in women. Women who identified more with other women, and men who identified less with other men showed greater risk tolerance. Digit ratio was not associated with risk tolerance. Further research focused on psychological gender and risk tolerance is emphasized.

Abstract:
We examined how young adults' use of instant messaging, text messaging, and traditional reading related to their self-reported experience of distractibility and impulsiveness and to their performance on computerized tasks designed to assess inattention and impulsive responses to visual stimuli. Participants reported their media use and completed self-report measures of impulsiveness (i.e., the Barratt Impulsiveness Scale) and distractibility for academic reading. They also completed performance based measures of inattention and impulsiveness using the Tests of Variables of Attention (T.O.V.A.®). Results demonstrated that instant message use was significantly related to higher levels of attentional impulsiveness and distractibility on the self-report measures, while traditional reading consistently predicted lower levels of impulsiveness and distractibility. However, media use was not significantly related to the performance measures of inattention and behavioral impulsiveness.

Training-Induced Changes in Inhibitory Control Network Activity
Elliot Berkman, Lauren Kahn & Junaid Merchant
Journal of Neuroscience, 1 January 2014, Pages 149-157
Abstract:
Despite extensive research on inhibitory control (IC) and its neural systems, the questions of whether IC can be improved with training and how the associated neural systems change are understudied. Behavioral evidence suggests that performance on IC tasks improves with training but that these gains do not transfer to other tasks, and almost nothing is known about how activation in IC-related brain regions changes with training. Human participants were randomly assigned to receive IC training (N = 30) on an adaptive version of the stop-signal task (SST) or an active sham-training (N = 30) during 10 sessions across 3 weeks. Neural activation during the SST before and after training was assessed in both groups using functional magnetic resonance imaging. Performance on the SST improved significantly more in the training group than in the control group. The pattern of neuroimaging results was consistent with a proactive control model such that activity in key parts of the IC network shifted earlier in time within the trial, becoming associated with cues that anticipated the upcoming need for IC. Specifically, activity in the inferior frontal gyrus decreased during the implementation of control (i.e., stopping) and increased during cues that preceded the implementation of IC from pretraining to post-training. Also, steeper behavioral improvement in the training group correlated with activation increases during the cue phase and decreases during implementation in the dorsolateral prefrontal cortex. These results are the first to uncover the neural pathways for training-related improvements in IC and can explain previous null findings of IC training transfer.

Abstract:
When regulating negative emotional reactions, one goal is to reduce physiological reactions. However, not all regulation strategies succeed in doing that. We tested whether heart rate biofeedback helped participants reduce physiological reactions in response to negative and neutral pictures. When viewing neutral pictures, participants could regulate their heart rate whether the heart rate feedback was real or not. In contrast, when viewing negative pictures, participants could regulate heart rate only when feedback was real. Ratings of task success paralleled heart rate. Participants’ general level of anxiety, emotion awareness, or cognitive emotion regulation strategies did not influence the results. Our findings show that accurate online heart rate biofeedback provides an efficient way to down-regulate autonomic physiological reactions when encountering negative stimuli.

European Journal of Personality, forthcoming
Abstract:
The personality trait of sensation seeking (SS) has been traditionally linked to the construct of exteroception, that is, sensing of the outside world. Little is known about the relationship between SS and interoception, that is, sensing originating in the body. Interoceptive sensations have strong affective and motivational components that may influence behaviours such as risk taking in SS. This investigation examined whether interoceptive differences contribute to different behavioural characteristics in SS. Using an inspiratory resistive load breathing task, the response to an aversive interoceptive stimulus as a basic homeostatic process was studied in 112 subjects (n = 74 women and 38 men). A linear mixed-model approach was used to examine the influence of thrill and adventure seeking (TAS) on the interoceptive response across three levels of breathing resistances (10, 20, and 40 cm H2O/L/second). High-TAS relative to low-TAS individuals were less responsive in evaluating intensities of perceived choking with increasing inspiratory resistive loads. This effect was driven by male, but not female, high-TAS individuals and was particularly associated with reduced interoceptive sensitivity in men. The conceptualization of SS as primarily driven by exteroceptive stimuli can be expanded to a view of an altered homeostasis in SS, specifically in men.

Heart Rate Variability Predicts Control Over Memory Retrieval
Brandon Gillie, Michael Vasey & Julian Thayer
Psychological Science, forthcoming
Abstract:
Stopping retrieval of unwanted memories has been characterized as a process that requires inhibition. However, little research has examined the relationship between control over memory retrieval and individual differences in inhibitory control. Higher levels of resting heart rate variability (HRV) are associated with greater inhibitory control, as indicated by better performance on a number of cognitive, affective, and motor tasks. Therefore, we tested the hypothesis that higher levels of resting HRV predict enhanced memory inhibition as indexed by performance on the think/no-think task. Efforts to suppress no-think word pairs resulted in impaired recall for those items, as in past studies. Moreover, higher levels of resting HRV were associated with more successful suppression, as indicated by lower recall of the to-be-avoided stimuli relative to baseline stimuli. These findings are among the first to suggest that physiological markers of inhibitory control can be used to index a person’s capacity to control unwanted memories.
