Despite adolescence and emerging adulthood being a time of peak physical ability, it is marked by a dramatic increase in morbidity and mortality, primarily driven by poor behavioral and emotional control (Dahl, 2004). Multiple lines of recent research are now focusing on how maturation of decision-making impacts risk-taking, and more specifically, what role emotion regulation plays (Weinberger et al., 2005; Steinberg, 2007). Rather than avoiding risk factors, a call is made for strength and skills-based approaches to risk-taking interventions. The purpose of the current exploratory study was to assess the efficacy of an experiential learning (EL) intervention designed to increase participants’ emotion regulation skills and decrease risk-taking. Twenty-eight emerging adults participated; 15 were assigned to the experimental group and presented with two separate sessions on emotional regulation and risk-taking using EL methodology (low and high element activities). The control group’s 13 participants were presented with two separate powerpoint lectures on emotion regulation and risk-taking. Participants’ difficulty with emotion regulation and risk-taking were assessed prior to the first session, between sessions, and one week following the second session. Qualitative interviews assessed participants’ understanding of how emotions and risk-taking are connected and process measures assessed the emotional impact of the intervention activities. While hypotheses were not confirmed, results revealed a significant decline in difficulty with emotion regulation across time for all participants. Unexpectedly, however, there were no significant differences between the groups on emotional regulation and the group x time interaction was also not significant. Additionally, risk-taking significantly increased across time. The control group reported more risk-taking across the three time periods than the experimental group. The time x group interaction approached significance [F(2,56) =2.68, p =.07], showing consistent increases for the control group but relatively low levels for the experimental group. Qualitative data revealed that participants had clear notions of how emotions drive risk-taking, how the thrill of risk- taking can be used to displace negative feelings, and how one’s need to connect to others can lead to risk-taking. Experimental group participants demonstrated a shift from global thinking about emotions and risk-taking to more specific thoughts about emotional awareness as a key skill. / text

Individual variation and limited plasticity in behavior are factors that have been shown to shape populations and determine how well individuals are doing in different stages of life. When salmon transform from parr to smolt and start the migration out to sea many factors together make an individual successful. The hypothesis of this study was that the boldness of individual smolt (1 and 2 year olds) is correlated to their inclination to migrate downstream. The study also investigated difference in boldness and migration tendency between 1- and two year old smolt. Today, some hatcheries release smolt as both one and two year old and it is important to know whether there is any difference in behavior and migration intensity between age classes in order to make stocking programs more effective. To determine if the individuals differed in boldness, and/or displayed a bold behavioral type, two assays were performed in different contexts (novel environment and simulated predatory attack). Downstream migratory intensity was, after behavior assays, quantified in an artificial stream. I found that: i) the one year old smolts tended to be bolder in a predatory response assay than two year old smolt, ii) one year old smolts migrated less in the artificial stream compared to two year old smolt. Being bolder can have an effect on several aspects connected to fitness in the salmon life cycle and could affect the survival of a smolt migrating out to sea, even though no correlations to inclination to downstream migration were found in this study.

Adolescence is a time associated with increased risk taking and peer relations. Research has shown that adolescents are more vulnerable to peer pressure compared to adults, leading to exacerbated risk taking. Preclinical research suggests that these findings may also be applicable to adolescent rodents, which find social interaction rewarding and are prone to risky behavior. There is, however, little research on the effect of social interaction on rodent models of risky decision-making. This thesis utilized social chambers, which consisted of adjacent operant chambers separated by wire mesh. Adolescent rats performed a risky decision-making task in which they had a choice between a small and large reward (associated with a mild footshock, which increased in probability across the session). Experiment 1 determined if the presence of peer altered performance on the task after stability. Experiment 2 determined if the presence of a peer altered performance on the task during acquisition. Results of Experiment 1 revealed no significant changes. Results from Experiment 2 revealed a significant increase in preference for the risky reward in the group of rats that had daily exposure to a social peer. These results provide evidence that social influence on risk taking can be modeled in rodents.

Using a novel setting, I examine the relation between a CEO's career concerns and the provision of an annual earnings forecast. Specifically, I exploit staggered changes in non-compete enforcement laws in three U.S. states as a source of exogenous variation in a CEO’s career concerns. Consistent with theory suggesting that career concerns increase a manager's aversion to risk, I find that a CEO is less likely to issue an earnings forecast in periods of stricter non-compete enforcement. Further, cross-sectional analyses indicate that the lower probability of forecast issuance is more pronounced for a CEO who has greater concern for his reputation, faces more risk in forecasting, and is more vulnerable to dismissal.

Positive and negative outcome expectancies have been found to play a significant role in adolescents' decisions to engage in drug and alcohol use. In light of the parallel risk and protective factors among high-risk behaviors, youth gambling outcome expectancies were explored through the development of the 23-item Gambling Expectancy Questionnaire (GEQ) using a sample of 1,013 students aged 12-18. The final GEQ consists of three positive expectancy scales (i.e., Enjoyment/Arousal, Self-Enhancement, Money) and two negative expectancy scales (i.e., Over-Involvement, Emotional Impact). Significant gender, age and DSM-IV-MR-J gambling group differences were identified on the scales of the GEQ. Stepwise logistic regression among gamblers was performed separately for males and females to predict group membership into either social or problem gambling categories. The results of this study suggest that non-gamblers, social gamblers, at-risk gamblers and PPGs differ in their expectancies of the positive and negative outcomes of gambling behavior. In particular, PPGs highly anticipate both the positive and negative outcomes of gambling. Among males, these perceptions differentiate those who gamble excessively and those who do not. For females, on the other hand, outcome expectancies may have less predictive value. These findings were interpreted in terms of their implications for prevention, treatment and future research.

The dramatic increase in the masculine practice of tattooing among girls in Western societies is an area of interest for feminist researchers and visual culture educators. Girls’ tattoos are perceived as diverse practices of conformity, resistance, reclamation, and empowerment, and/or as contemporary markers of femininity, sexuality, and desire. Eleven adolescent girls with tattoos from the Central Okanagan region of British Columbia were interviewed during a 12 month period in 2007/2008. Discourse analysis was employed as a method to interpret and deconstruct girls’ narratives with respect to understanding why girls have adopted traditional Western male practices of tattooing as expressions of individuality or identity. Secondly, responses were examined with respect to girls’ knowledge of potential risks involved with tattooing. The majority of participants had strong attachments to their relatives and their tattoos signified a desire to maintain that close family relationship. Research findings indicated girls’ mothers were influential in their daughters’ decisions to get tattooed and in the type of image tattooed. Girls were adamant that popular media figures with tattoos and advertisements of models with tattoos could influence or encourage girls to engage in body art. Knowledge of potential risks was learned primarily from tattoo artists and relatives, with infection indicated as the main associated risk. Participants suggested the distribution of pamphlets in school counseling centres could inform students of potential risks and provide information related to safe body art practices. Participants believed societal norms respecting girls’ behaviors and practices were different than those experienced by their mothers. However size, placement, and image of their tattoos, their own biases, and their experiences with older relatives including grandmothers and some fathers indicate that traditional Western attitudes regarding femininity and the female body continue. In spite of this, girls believe that they have the freedom to choose how they enact femininity and assert their individuality, and they believe “if guys can do it, so can girls”. As visual culture educators we need to listen to and respect the voices of girls to achieve a greater understanding of how girls experience and perform gender through their everyday practices within the popular visual culture.

Risk-sensitivity theory predicts that decision-makers shift from risk-aversion to riskpreference in situations where low-risk options are unlikely to meet their needs. Risksensitive theory is contrasted with more traditional unbounded models of decision-making predicting that decision-makers seek to optimize utility in all decisions. In this dissertation, I review influential theories of decision-making from the various behavioral sciences, and offer an integrated approach to understanding decision-making informed by evolutionary theory. I then present evidence suggesting that risk-taking comprises a general phenomenon, inclusive of such behaviors as gambling and antisocial conduct. Finally, I demonstrate in several laboratory experiments that conditions of need, such as inequality, are important motivators of risky behavior. Together, the results suggest that risk-taking represents a functional triggering of preference for variable outcomes in response to conditions of need, consistent with risk-sensitivity theory. / xiv, 149 leaves ; 29 cm

The number of women infected with the HIV virus through heterosexual contact is on the rise and expected to increase steadily throughout the 1990's. In order to prevent the further spread of HIV infection and AIDS, behavior change is essential. The focus of this study is on the sexual behaviors, safe sex practices, and the role that self-efficacy and self-assertiveness play in a woman's ability to put into effect preventative behaviors. The study sample consists of 40 heterosexual, English-speaking women from the Montreal area. The results indicate that just under half of this population are using condoms as a safe sex precaution, but they are being used inconsistently. Those participants who reported sometimes using condoms were also the same participants who more frequently reported modifying other aspects of their sexual behavior in order to reduce their risk of infection, as compared to those participants who did not report using condoms. It was also found that the participants' past sexual history, knowledge about HIV transmission, and awareness of risky sexual practices do not predict more cautious sexual behavior. One major factor which did seem to influence modification of risky sexual behaviors was the participants' perception of being at risk for HIV. The majority of the participants did not have difficulty in asserting their desire for safe sex. Their methods, however, in how they would choose to practise safe sex were dependent on the seriousness of the relationship, ability to trust their partner, and their current method of practising safe sex in their own sexual lives.
