Description
Previous research indicates that difficulties in emotion regulation and greater dissociation from one's emotions are often observed among trauma survivors. Further, trauma survivors often show greater negative emotions such as anger, and diminished positive emotions such as happiness. Relatively less is known about the relationship between posttraumatic stress symptoms, dissociation, emotion regulation difficulties, and non-trauma related emotional experiences in daily life. This study examined whether greater reports of posttraumatic stress symptoms, difficulties in emotion regulation, and dissociative tendencies were associated with greater intensity of anger and lower intensity of happiness during a relived emotions task (i.e., recalling and describing autobiographical memories evoking specific emotions). Participants were 50 individuals who had experienced a traumatic event and reported a range of posttraumatic stress symptoms. Participants rated how they felt while recalling specific emotional memories, as well as how they remembered feeling at the time of the event. Results showed that dissociative tendencies was the best predictor of greater intensity of anger and, contrary to the hypothesis, dissociative tendencies was predictive of greater happiness intensity as well. These findings are consistent with previous research indicating a paradoxical effect of heightened anger reactivity among individuals with dissociative tendencies. In addition, researchers have argued that individuals with a history of traumatization do not report lower positive emotional experiences. The present findings may suggest the use of dissociation as a mechanism to avoid certain trauma related emotions (e.g, fear and anxiety), in turn creating heightened experiences of other emotions such as anger and happiness.

Description
The objective of this study was to examine the potential effects of long term hormone replacement therapy on cardiovascular autonomic nervous system responses to laboratory social stressors. The participants were 38 postmenopausal women, 18 using estrogen and progesterone hormone replacement therapy for at least 2 years and 20 control participants without hormone replacement therapy. All women completed orthostasis (standing and sitting), then speech and math tasks (speech and math were counterbalanced). Cardiovascular measures of sympathetic nervous system (pre-ejection period, PEP) and parasympathetic nervous system (respiratory sinus arrhythmia, RSA) along with heart rate were collected throughout all periods (baseline, orthostasis, and stressors). For orthostasis, results of mixed analyses of variance (ANOVAs) showed expected period effects for heart rate, RSA and PEP, but no group or group by period interaction was significant. For the psychological stressors, period main effects were significant for all three variables, suggesting that the tasks were effective at inducing stress. Also, there was a significant interaction between group and period for RSA, demonstrated by greater decrease during the psychological stressor period in the group using HRT. The interactions between group and period for heart rate and PEP were non-significant. These findings support the notion that HRT may slow age-related decreases in parasympathetic responsiveness. Furthermore, changes in vagal reactivity in relation to use of HRT appear to occur within mechanisms involving response and coping with psychological stressors, rather than mechanisms that accommodate basic physiological task such as orthostasis.

Recent research has identified affirmation of transcendence and exposure to violent Bible verses as being related to greater prejudice toward value-violating out-groups (Blogowska & Saroglou, 2012; Shen et al., 2013). Effects of exposure to specific Bible verses on attitudes toward out-groups have not been measured in combination with the Post-Critical Belief Scale developed by Hutsebaut (1996). The relationships between exposure to scriptural endorsements of prejudice, affirmation vs. disaffirmation of transcendence, literal vs. symbolic processing of religious content, and prejudice toward value-violating out-groups were examined using an online survey administered to a sample of U.S. adults (N=283). Greater affirmation of transcendence scores were linked to greater prejudice toward atheists and homosexuals and more favorable ratings of Christians and highly religious people. Lower affirmation of transcendence scores were linked to less favorable ratings of Christians and highly religious people and more favorable ratings of atheists. Exposure to scriptural endorsements of prejudice did not have a significant effect on levels of prejudice in this study.

Description
Previous studies have established a link between parenting style (e.g. authoritarian, authoritative, permissive) and depression in children and adolescents. Parenting factors are also implicated in the development of emotion regulation. There is a gap in the literature, however, concerning perceptions of parenting in relation to adult depression. The current study examined the effect of parenting on reported adult depressive symptoms. Of interest was the role of emotion regulation strategies in this relationship. Participants were recruited through Amazon Mechanical Turk, and the sample consisted of 302 adults (125 males, 177 females) ranging in age from 18 to 65. Measures of how participants were parented by their mothers and fathers, emotion regulation strategies most frequently utilized, and current depressive symptoms were collected using an online survey. The emotion regulation strategy, positive reappraisal, was found to moderate the relation between maternal authoritative parenting and depression. Permissive parenting was also significantly predictive of depression, but catastrophizing fully mediated only the relation between maternal permissive parenting and depressive symptoms. Authoritarian parenting was unrelated to depression and emotion regulation in this study. The findings of this study indicate that the effects of how an individual was parented may persist into adulthood. Implications of these findings and future directions for further research are discussed.

A sample of 193 participants viewed one of six variations of an eyewitness giving mock testimony. Each participant viewed testimony, which varied by level of emotion (none, moderate, or high) and frame (waist-up or head only). Participants then rated the witness using the Brodsky Witness Credibility Scale and the Reyson Likability Scale. A set of ANOVA's was performed revealing an effect of emotion level on both credibility and likability. Emotion level was found to influence participant judgments of poise, however, to a lesser degree than judgments of credibility and likability. These results suggest that attorneys may want to avoid the use of videoconferencing with certain types of witnesses where testimony may be highly emotional.

Description
Protectors who do harm are often punished more severely because their crime is perceived as a betrayal of trust. Two experiments test whether this will generalize to protectors who incur harm while serving in their protective role, and if not, whether collective guilt for the harm they suffered provides an explanation. Study 1 tested competing hypotheses that a veteran (versus civilian) with PTSD would be punished either more harshly because of the trust betrayal, or more leniently because of increased guilt about the harm the veteran suffered during war. Men and women were both more lenient toward a veteran (versus civilian) but this effect was mediated by collective guilt only among men. In Study 2, guilt inductions increased leniency among participants less likely to classify the veteran as an in-group member (women, low national identifiers), but not in those who are more likely to classify the veteran as an in-group member (men, high national identifiers), who were lenient without any guilt inductions.

Deoxyribonucleic Acid (DNA) evidence has been shown to have a strong effect on juror decision-making when presented in court. While DNA evidence has been shown to be extremely reliable, fingerprint evidence, and the way it is presented in court, has come under much scrutiny. Forensic fingerprint experts have been working on a uniformed way to present fingerprint evidence in court. The most promising has been the Probabilistic Based Fingerprint Evidence (PBFE) created by Forensic Science Services (FSS) (G. Langenburg, personal communication, April 16, 2011). The current study examined how the presence and strength of DNA evidence influenced jurors' interpretation of probabilistic fingerprint evidence. Mock jurors read a summary of a murder case that included fingerprint evidence and testimony from a fingerprint expert and, in some conditions, DNA evidence and testimony from a DNA expert. Results showed that when DNA evidence was found at the crime scene and matched the defendant other evidence and the overall case was rated as stronger than when no DNA was present. Fingerprint evidence did not cause a stronger rating of other evidence and the overall case. Fingerprint evidence was underrated in some cases, and jurors generally weighed all the different strengths of fingerprint testimony to the same degree.

Description
Researchers have found inconsistent effects (negative or positive) of social relationships on self-control capacity. The variation of findings may depend on the aspects of social relationships. In this study, rather than examining overall social relationships and self-control, characteristics in social relationships were clearly defined, including social support, social connection and social conflict, to determine their specific effects on self-control. An online survey study was conducted, and 292 college students filled out the survey. For data analysis, path analysis was utilized to examined the direct effect and indirect effect from social relationships to self-control. Results showed social connection and social conflict may indirectly associate with self-control through stress, but social support does not. It may suggest, in traditional stress buffering model, it is the social connection in social support that really reduce the stress. Concerning the direct effects, social support and social connection were significantly associated with self-control directly, but social conflict does not. This result may support the Social Baseline Theory that positive social relationships have direct regulating effects. Results are good for guidance of experimental manipulation of social relationships in study of social influences of self-control.

Description
A model of the effects of early adolescents' temperament (negative emotionality and inhibitory control) and threat appraisals on resulting status in the bullying dynamic was examined. Specifically, I examined the hypothesis that negative emotionality and passive victim versus bully-victim status would be mediated by threat appraisals, and that mediated effect would be moderated by levels of inhibitory control. The study used a sample of 56 early adolescents ages 7–16. Temperament characteristics were measured using the EATQ–R (Capaldi & Rothbart, 1992). Threat appraisals were assessed using items from Hunter, Boyle, and Warden (2004). Bullying and victimization were measured using items created for this study and additional cyber bullying items (Smith, Mahdavi, Carvalho, & Tippett, 2006). A multinomial logistic regression and test of moderated mediation were analyzed to examine the model (Hayes, 2012). Higher levels of negative emotionality were correlated with being a victim of bullying. The moderated mediation model was not statistically significant, however the direction of the patterns fit the hypotheses. Future directions and limitations are discussed.

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.
