Description
Despite a large body of research on stereotypes, there have been relatively few empirical investigations of the content of stereotypes about Native Americans. The primary goal of this research was to systematically explore the content of cultural stereotypes about Native Americans and how stereotypes about Native Americans differ in comparison to stereotypes about Asian Americans and African Americans. Building on a classic paradigm (Katz and Braly, 1933), participants were asked to identify from a list of 145 adjectives those words associated with cultural stereotypes of Native Americans and words associated with stereotypes of Asian Americans (Study 1) or African Americans (Study 2). The adjectives associated with stereotypes about Native Americans were significantly less favorable than the adjectives associated with stereotypes about Asian Americans, but were significantly more favorable than the adjectives associated with stereotypes about African Americans. Stereotypes about Native Americans, Asian Americans and African Americans were also compared along the dimensions of the stereotype content model (SCM; Fiske, et al., 2002), which proposes that stereotypes about social groups are based on the core dimensions of perceived competence, warmth, status, and competitiveness. Native Americans were rated as less competent, less of a source of competition, and lower in social status than Asian Americans, and less competent and lower in social status than African Americans. No significant differences were found in perceived warmth across the studies. Combined, these findings contribute to a better understanding of stereotypes about Native Americans and how they may differ from stereotypes about other racial groups.

Description
The current study examines the role that context plays in hackers' perceptions of the risks and payoffs characterizing a hacktivist attack. Hacktivism (i.e., hacking to convey a moral, ethical, or social justice message) is examined through a general game theoretic framework as a product of costs and benefits, as well as the contextual cues that may sway hackers' estimations of each. In two pilot studies, a bottom-up approach is utilized to identify the key motives underlying (1) past attacks affiliated with a major hacktivist group, Anonymous, and (2) popular slogans utilized by Anonymous in its communication with members, targets, and broader society. Three themes emerge from these analyses, namely: (1) the prevalence of first-person plural pronouns (i.e., we, our) in Anonymous slogans; (2) the prevalence of language inducing status or power; and (3) the importance of social injustice in triggering Anonymous activity. The present research therefore examines whether these three contextual factors activate participants' (1) sense of deindividuation, or the loss of an individual's personal self in the context of a group or collective; and (2) motive for self-serving power or society-serving social justice. Results suggest that participants' estimations of attack likelihood stemmed solely from expected payoffs, rather than their interplay with subjective risks. As expected, the use of we language led to a decrease in subjective risks, possibly due to primed effects of deindividuation. In line with game theory, the joint appearance of both power and justice motives resulted in (1) lower subjective risks, (2) higher payoffs, and (3) higher attack likelihood overall. Implications for policymakers and the understanding and prevention of hacktivism are discussed, as are the possible ramifications of deindividuation and power for the broader population of Internet users around the world.

Description
ABSTRACT Post-Traumatic Stress Disorder (PTSD), depression, and insomnia are prevalent among United States (US) military veterans. This study investigates whether Brain Boosters, a new cognitive enhancement group therapy, improves symptoms of PTSD, depression, and insomnia among veterans completing the groups. The study population includes 64 US military veterans treated in the setting of the Veterans Affairs (VA) Health Care System in Phoenix, AZ. Group members were US military veterans, age 22 to 87 (mean age=53.47), who had served in or after World War II (WWII), who sought mental health care at the Phoenix VA from 2007 through 2011. Participants were treated with Brain Boosters therapy. They completed measures of mental-health related symptoms before and after this therapy. Participants were assessed pre and post group with the PTSD Checklist for military personnel (PCL-M), the Patient Health Questionnaire (PHQ-9; a measure of depression symptoms), and the Insomnia Severity Index (ISI). Statistical analyses were done with paired samples t-tests and McNemar's tests, using SPSS. The hypotheses were that symptoms of PTSD, depression, and insomnia would show statistically significant improvement with Brain Boosters therapy. Results supported the hypotheses that symptoms of PTSD and depression would improve significantly. Insomnia did not show significant improvement. The results showed the mean PCL-M score was 54.84 before Brain Boosters therapy and 51.35 after (p= 0.008). The mean PHQ-9 score was 15.21 before Brain Boosters therapy and 13.05 after (p= 0.002). The mean ISI score was 15.98 before Brain Boosters Therapy and 14.46 after (p= 0.056). Although this is a nonrandom, uncontrolled trial, findings nevertheless suggest that Brain Boosters may be an effective therapy to reduce PTSD symptom severity and depression symptom severity. This may be especially important for veterans seeking alternatives to pharmacological intervention or traditional therapeutic interventions.

Description
Beliefs about change reflect how we understand phenomena and what kind of predictions we make for the future. Cyclical beliefs about change state that events are in a constant flux, and change is inevitable. Linear beliefs about change state that events happen in a non-fluctuating pattern and change is not commonplace. Cultural differences in beliefs about change have been documented across various domains, but research has yet to investigate how these differences may affect health status predictions. The present study addresses this gap by inducing different beliefs about change in a European-American college sample. Health status predictions were measured in terms of predicted likelihood of exposure to the flu virus, of contraction of the flu, and of receiving a flu vaccine. Most differences were observed among those who have a recent history of suffering from the flu. Among them, cyclical thinkers tended to rate their likelihood for exposure and contraction to be higher than linear thinkers. However, linear thinkers indicated that they were more likely to receive a flu vaccine. The different patterns suggest the possibility that cyclical beliefs may activate concepts related to cautionary behaviors or pessimistic biases, while linear beliefs may activate concepts related to taking action and exercising control over the environment. Future studies should examine the interplay between beliefs about change and the nature of the predicted outcome.

Description
Emotion regulation repertoire, or the number of emotion regulation strategies one is able to employ when needed, is an important element of emotion regulation flexibility. Emotion regulation flexibility, the ability to regulate in accordance with changing situational contexts and demands, is predictive of emotion regulation success. Currently, little is known about emotion regulation repertoire and its association with emotional health and well-being. In particular, more can be learned about how the different strategies in one’s repertoire interact, and which strategies show stronger relationships with mental health. The current study aimed to assess the relationship of different emotion regulation strategies to mental health, including their individual and combined influence. In addition, the interaction between the use of specific emotion regulation strategies and emotion regulation flexibility with respect to mental health was examined. I hypothesized (1a) reappraisal and (1b) acceptance, two strategies previously associated with positive psychological outcomes, would be significant predictors of mental health, and (2) better flexibility would predict better mental health. In addition, I hypothesized that (3) strategies often found to be maladaptive (suppression, distraction, rumination, and experiential avoidance) would have an inverse relationship with mental health. Finally, (4) maladaptive strategies would be associated with worse mental health for those lower in flexibility. These hypotheses were tested through a questionnaire as part of a larger in-lab study. Results revealed that reappraisal and rumination were the strongest predictors of mental health. Emotion regulation flexibility did not predict mental health or moderate the relationship between individual emotion regulation strategies and mental health. Results from this study suggest some emotion regulation strategies are stronger predictors of mental health than others. This will guide future research on specific emotion regulation strategies in a repertoire as well as their combined effect on mental health. Creating a clearer picture of how different strategies interact and influence mental health will also be vital for clinical interventions.

Description
Individuals differ in the extent to which they feel connected to their future selves, which predicts time preference (i.e., preference for immediate versus delayed utility), financial decision-making, delinquency, and academic performance. Future self-connectedness may also predict how individuals compare themselves with their past selves, future selves, and other people. Greater connectedness may lead to more self-affirming types of temporal self-comparison, less self-deflating types of temporal self-comparison, and less social comparison. Two studies examined the relation between future self-connectedness and comparison processes, as well as effects on emotion, psychological adjustment, and motivation. In the first study, as expected, future self-connectedness positively predicted self-affirming temporal self-comparison and negatively predicted self-deflating temporal self-comparison and social comparison. In addition, future self-connectedness had beneficial direct and indirect effects on adjustment, emotion regulation, and motivation. Unlike previous research, this study examined all three components of future self-connectedness, as opposed to only one. Exploratory analyses examined the items comprising the similarity-connectedness component and found that the relation of these items to the other variables in the model did not differ, though some of the relations in the model were moderated by college generation status. The second study tested whether increasing future self-connectedness would have similar effects on comparison, adjustment, emotion, and motivation. It implemented a pilot future self-connectedness manipulation, an established identity-stability manipulation, and a control condition. The pilot manipulation and identity-stability manipulation failed to affect future self-connectedness relative to control, and did not affect comparison, motivation, adjustment, or emotion. Future research should ascertain whether there is a causal link between connectedness and social comparison or temporal self-comparison processes. Overall, this research links future self-connectedness to social comparison and temporal self-comparison processes, as well as well-being, emotion, and motivation, which demonstrates the importance of connectedness in new, important areas.

Description
Social scientists from many disciplines have examined trust, including trust between those with different religious affiliations, emotional antecedents of trust, and physiological correlates of trust. However, little is known about how all of these factors intersect to shape trust behaviors. The current study aimed to examine physiological responses while individuals engaged in a trust game with a religious in-group or out-group member. Participants were randomly assigned to one of four conditions in which they were presented with the target’s profile before playing the game. In each of the conditions the target was described as either Catholic or Muslim and as someone who engaged in either costly signaling or anti-costly signaling behavior. In addition to assessing the amount of money invested as a behavioral measure of trust, physiological responses, specifically cardiac interbeat interval (IBI) and respiratory sinus arrhythmia (RSA), were measured. I hypothesized that when playing the trust game with a Catholic target as opposed to a Muslim target, Christian participants would (1) report being more similar to the target, (2) trust the target more, (3) invest more money in the target, (4) have a more positive outlook on the amount invested, and (5) show greater cardiorespiratory down-regulation, reflected by increases in IBI and RSA. Findings revealed that Christian participants reported greater similarity and showed a non-significant trend toward reporting a more positive outlook on (greater confidence in/satisfaction with) their investment decision when playing a Catholic versus Muslim target. Additionally, Christian participants who played an anti-costly signaling Catholic target showed greater cardiorespiratory down-regulation (increases from baseline for IBI, reflecting slower heart rate, and increases in RSA) than Christian participants who played an anti-costly signaling Muslim target. Results from this study echo previous findings suggesting that perceived similarity may facilitate trust. Findings also are consistent with previous research suggesting that religious ingroup or outgroup membership may not be as influential in shaping trust decisions if the trustee is costly signaling; for anti-signaling, however, cardiorespiratory down-regulation to a religious ingroup member may be apparent. These physiological signals may provide interoceptive information about a peer’s trustworthiness.

Description
Prophylactic bilateral mastectomy (PBM) is the current recommended course of action for women with increased genetic risk for breast and ovarian cancer. Nevertheless, many receive negative feedback from family and friends surrounding the decision to undergo this surgery because they do not have cancer when the decision is made; this results in a limited support network for coping with their PBM. Low social support is associated with depression, negativity, and anxiety. Women who had a PBM, were currently undergoing or had completed reconstruction, and were in a committed romantic relationship at the time of the surgery were surveyed (N = 53). The hypotheses that women who received negative feedback about their decision to have a PBM would have poorer individual well-being, and that the use of a couples-based team approach would moderate these adverse effects were tested. Data analyses support the hypotheses that women in couples taking a team approach to PBM have better individual well-being. The effects of negative feedback from others about the decision to undergo a PBM on personal mental health were moderated by use of a couples-based team approach. Women who received negative feedback from multiple sources had better outcomes if they used a couples-based team approach. Many women have a preventative oophorectomy around the same time as their PBM. Menopause is associated with side effects such as increased vasomotor symptoms and decreased sexual functioning. The hypothesis that surgical menopause is related to declines in sexual satisfaction following PBM was also tested. Regression analysis revealed no relationship. This study indicates that women who experience social disapproval and lack collaborative support from their significant other may be at increased risk for poor individual well-being following PBM.

Description
An increasing number of military veterans are enrolling in college, primarily due to the Post-9/11 GI Bill, which provides educational benefits to veterans who served on active duty since September 11, 2001. With rigorous training, active combat situations, and exposure to unexpected situations, the veteran population is at a higher risk for traumatic brain injury (TBI), Post Traumatic Stress Disorder (PTSD), and depression. All of these conditions are associated with cognitive consequences, including attention deficits, working memory problems, and episodic memory impairments. Some conditions, particularly mild TBI, are not diagnosed or treated until long after the injury when the person realizes they have cognitive difficulties. Even mild cognitive problems can hinder learning in an academic setting, but there is little data on the frequency and severity of cognitive deficits in veteran college students. The current study examines self-reported cognitive symptoms in veteran students compared to civilian students and how those symptoms relate to service-related conditions. A better understanding of the pattern of self-reported symptoms will help researchers and clinicians determine the veterans who are at higher risk for cognitive and academic difficulties.

Description
Decades of research in cyberpsychology and human-computer interaction has pointed to a strong distinction between the online and offline worlds, suggesting that attitudes and behaviors in one domain do not necessarily generalize to the other. However, as humans spend increasing amounts of time in the digital world, psychological understandings of safety may begin to influence human perceptions of threat while online. This dissertation therefore examines whether perceived threat generalizes between domains across archival, correlational, and experimental research methods. Four studies offer insight into the relationship between objective indicators of physical and online safety on the levels of nation and state; the relationship between perceptions of these forms of safety on the individual level; and whether experimental manipulations of one form of threat influence perceptions of threat in the opposite domain. In addition, this work explores the impact of threat perception-related personal and situational factors, as well as the impact of threat type (i.e., self-protection, resource), on this hypothesized relationship.
Collectively, these studies evince a positive relationship between physical and online safety in macro-level actuality and individual-level perception. Among individuals, objective indicators of community safety—as measured by zip code crime data—were a positive reflection of perceptions of physical safety; these perceptions, in turn, mapped onto perceived online safety. The generalization between perceived physical threat and online threat was stronger after being exposed to self-protection threat manipulations, possibly underscoring the more dire nature of threats to bodily safety than those to valuable resources. Most notably, experimental findings suggest that it is not the physical that informs the digital, but rather the opposite: Online threats blur more readily into physical domains, possibly speaking to the concern that dangers specific to the digital world will bleed into the physical one. This generalization of threat may function as a strategy to prepare oneself for future dangers wherever they might appear; and indeed, perceived threat in either world positively influenced desires to act on recommended safety practices. Taken together, this research suggests that in the realm of threat perception, the boundaries between physical and digital are less rigid than may have been previously believed.
