Description
Using an integrated perspective of the Grief Work Hypothesis and Posttraumatic Growth Theory, this study was designed to contribute to the sparse existing cross-cultural research by examining and comparing individuals' emotional adjustment and posttraumatic growth in the United States (US) and China. Another main goal was to unfold the predictive effects of different dimensions of locus of control, coping strategies and social support on the outcomes and further, to explore cultural differences in the underlying mechanisms. Web-based survey was disseminated and administered in the US and China. One thousand and seventy-eight participants completed the survey and met the criteria such that they were eighteen years old or older and experienced death of a loved one six to thirty-six months ago. As expected, US participants experienced higher levels of subjective well-being, lower levels of complicated grief and posttraumatic growth than Chinese participants. They also reported higher external yet lower internal locus of control, less frequent use of active and avoidance coping, and less informational support and negative social interactions than their Chinese counterparts. No difference in emotional support was evidenced between the two cultures. After controlling for demographic, loss-related information and the impact of post-bereavement life events, hierarchical regression analyses revealed that culture, external locus of control, avoidance coping and negative social interactions were unique predictors of complicated grief. Furthermore, the relation between external locus of control and complicated grief was weaker for US participants compared to that for Chinese participants. Culture, external and internal locus of control, active and avoidance coping, and negative social interactions significantly predicted individuals' subjective well-being after the loss. Additionally, culture, internal locus of control, active and avoidance coping, informational support, and negative social interactions were identified as unique predictors of posttraumatic growth. Specifically, an interaction effect of avoidance coping x culture emerged such that avoidance coping significantly predicted posttraumatic growth only for US participants. This study extracted the underlying mechanisms of predicting individuals' emotional adjustment and personal growth following bereavement. The influence of culture was also highlighted. Application of existing theories to the Chinese culture and clinical implications of the current study were discussed.

Description
Over the past several years, engagement and embeddedness have become popular research topics for academics and practitioners alike. Research has demonstrated associations between these constructs and a variety of predictors and outcomes. Prior research has not, however, placed enough emphasis on the roles of employee type, industry type, and work setting in determining predictors and outcomes. Additionally, the relative roles of engagement and embeddedness in predicting outcomes have not been thoroughly investigated. This study investigated the predictors and outcomes of engagement and embeddedness among unskilled, production line employees working in food processing in the agricultural industry by conducting a survey of employees and their supervisors. Employees answered questions about personality, motivation, satisfaction, engagement, and embeddedness while supervisors answered questions about each employee's performance. Results suggest that both engagement and embeddedness predict employee satisfaction and that engagement does so more strongly, both of which support prior research. However, results contradict prior research by suggesting that embeddedness is strongly predicted by traits internal to the employee while engagement is not, and neither engagement nor embeddedness significantly predicts employee performance. Further, the findings suggest that employees working in different settings and industries may experience work differently, and the measurements used to understand their experiences should reflect these differences.

Description
Research in the area of childhood trauma has shown a substantial amount of psychological maladjustment following the experience of traumatic events in childhood. Trauma survivors are at risk for developing a multitude of adverse psychological outcomes as well as unsafe behaviors following the event of trauma. One unifying theme within these psychological sequelae is the nature of impulsive behaviors. Delay-discounting refers to the subjective decrease in value of a reward when its presentation is delayed. Delay-discounting is often used as an index of impulsive behavior. This study poses two primary questions: 1) Can childhood trauma predict rates of delay-discounting? 2) Could delay-discounting predict psychological maladjustment for individuals who have experienced childhood trauma? This study will seek to answer these questions using an online version of the Kirby et al., 1999 hypothetical delay-discounting method, as well as the Barratt Impulsiveness Scale (BIS-11), to measure trait impulsivity. Measures of depression (BDI-II), life events (LEC), post-traumatic stress (PCL-C), and drug and alcohol abuse (DAST-20) will also be included. Participants included a sample of university students ages 18-52 (n=521, females = 386, males = 135) with a mean age of 25.19 years. Results indicated that childhood trauma was not a significant predictor of delay-discounting rate, nor was delay-discounting rate a significant predictor of psychological maladjustment. Limitations and future directions are discussed.

Description
The unpleasant bitter taste found in many nutritious vegetables may deter people from consuming a healthy diet. We investigated individual differences in taste perception and whether these differences influence the effectiveness of bitterness masking. To test whether phenylthiocarbamide (PTC) `supertasters' also taste salt and sugar with greater intensity, as suggested by Bartoshuk and colleagues (2004), we infused strips of paper with salt water or sugar water. The bitterness rating of the PTC strip had a significant positive linear relationship with ratings of both the intensity of sweet and salt, but the effect sizes were very low, suggesting that the PTC strip does not give a complete picture of tasting ability. Next we investigated whether various seasonings could mask the bitter taste of vegetables and whether this varied with tasting ability. We found that sugar decreased bitterness and lemon decreased liking for vegetables of varying degrees of bitterness. The results did not differ by ability to taste any of the flavors. Therefore, even though there are remarkable individual differences in taste perception, sugar can be used to improve the initial palatability of vegetables and increase their acceptance and consumption.

Description
This study investigated whether research by researchers affiliated with a religious academic institution would be seen as of less scientific merit than research done by researchers affiliated with a nonreligious academic institution. Such a bias may exist given the different value systems underlying religion and science, the widespread perception of a conflict between religion and science, and research on differences in cognitive styles and stereotypes about religious versus nonreligious people. In this study, U.S. participants recruited from Amazon Mechanical Turk completed an online survey, which included an abstract of an article describing scientific research with authors’ names and academic institutions, and questions on perceived scientific merit, religiosity, spirituality, religion as Quest, and perceived conflict between religion and science. There was a significant difference in the perceived merit of the researchers, with the group believing the researchers were affiliated with a religious academic institution rating the research as lower in scientific merit than the group believing the researchers were affiliated with a nonreligious academic institution. The perceived level of conflict between religion and science was found to moderate the relationship, such that higher levels of perceived conflict between religion and science showed a greater difference in scientific merit between groups.

Description
This study investigated the relation between Sensory Processing Sensitivity (SPS) temperament and depression, and whether such a relation might be further influenced by the indirect effects of parenting environment and empathic personal distress. A moderated mediation model was proposed to explain the underlying relations among SPS, depression, parenting environment and empathic personal distress. That is, greater levels of SPS temperament might predict higher levels of empathic personal distress, which then leads to increasing likelihood of experiencing depression. Moreover, it was predicted that this mediation relation might be significantly stronger under a less positive parenting context. The present study recruited 661 participants from a U.S. university and implemented questionnaires in an online survey. There was a significant main effect of SPS temperament in predicting empathic personal distress and depression, such that the more sensitive individuals reported higher empathic personal distress and depression. There also was a significant main effect of parenting environment on depression, where more positive parenting was associated with less depression. Empathic personal distress was found to partially mediate the relation between SPS and depression. That is, the association between SPS and depression could be partially explained by empathic personal distress. However, parenting environment did not moderate the main effect of SPS temperament on depression, the main effect of SPS on empathic personal distress, or the mediation model.

Description
Touch appears to be an important component for understanding psychological and emotional well-being, as well as the formation and maintenance of interpersonal relationships later in life. While research about touch in relation to these topics is gaining momentum, there is still little evidence on the specific effects and processes that take place when touch is negative or harmful. The current study examined how women who have experienced physical or sexual abuse perceive touch in the context of interpersonal relations and in turn, how these experiences, perceptions and attitudes are related to depressive symptoms. Taking into consideration the significance of interpersonal touch, I speculated that 1) attitudes towards touch would be more negative among women who reported physical or sexual abuse than among women who did not; 2) among women who reported past abuse, increased abuse severity would predict increased current depressive symptoms; and 3) among women who reported past abuse, current attitudes towards touch would mediate the relationship between abuse severity and depressive symptoms. As predicted, results indicated that women who reported physical or sexual abuse had less positive attitudes towards touch than women who did not report any abuse. Echoing prior research, reports of childhood and adult abuse predicted increased depressive symptoms. Finally, for women who reported childhood abuse, Discomfort with Social Touch was a significant partial mediator of depressive symptoms, whereas for women who reported adult abuse, both Desire for More Partner Touch and Discomfort with Social Touch were significant partial mediators of depressive symptoms. Results suggested that negative attitudes towards general social touch, in particular, may play a strong role in mediating depressive symptoms among women who reported abuse.

Description
Numerous psychosocial and health factors contribute to perceived stress, social support, and problem-solving coping relating to overall well-being and life satisfaction in older adults. The effect of social support and problem-solving coping, however, remains largely untested as potential moderators. The present study was conducted to test whether social support and problem- solving coping would moderate the relation between perceived stress and life satisfaction in older adults. First, I anticipated that stress will be negatively related to life satisfaction at low levels of social support, while at high social support; stress will be unrelated to life satisfaction. Second, I expected that with low problem- solving coping, stress will be negatively related to life satisfaction, whereas, at levels of high problem- solving coping, stress will be unrelated to life satisfaction. Using an experimental survey and interview design with hierarchical regression analyses, I found no support that social support would moderate the relation between stress and life satisfaction. I found support that problem-solving coping moderated the relation between stress and life satisfaction. For individuals who engage in higher levels of problem- solving coping, higher levels of stress predicted lower levels of life satisfaction. On the other hand, at lower levels of problem-solving coping, more stress predicted lower levels of life satisfaction.

Description
Menopause is a complex biopsychosocial phenomenon that is influenced by women’s attitudes, the attitudes of their partners, families, and friends, and societal norms. Previous research has shown that attitudes can be influenced by many factors, such as age and menopausal status. This study examined men’s and women’s attitudes toward several facets of menopause, including fertility, attractiveness, personal growth, emotional stability, and sexuality, using an Amazon Mechanical Turk sample of 194 females and 151 males. Results revealed that women and men differed significantly in their attitudes toward fertility, attractiveness, personal growth, and sexuality, with women having more positive attitudes on every dimension except sexuality. For females, age was a significant positive predictor for fertility, personal growth, and emotional stability; knowledge was a significant positive predictor for personal growth; and education was a significant positive predictor for emotional stability. For males, age was a significant positive predictor for fertility, and knowledge was a significant negative predictor for fertility. These results indicate that men typically have more negative attitudes toward menopause than do women, and that more potential predictors of menopause attitudes should be explored in future work to provide insight into the reasons for this difference.

Description
For decades, researchers have found that jurors are consistently unable - or unwilling - to disregard inadmissible evidence when instructed to do so by a judge. The legal system ignores the problem entirely: judges have repeatedly affirmed that a judge’s instructions to disregard are a sufficient safeguard of defendants’ constitutional rights, regardless of whether the jury actually disregards the inadmissible evidence. This study tested four interventions derived from psychological research to identify the combination that most effectively helped jurors disregard inadmissible evidence (operationalized by lower conviction rates). It was hypothesized that the most effective interventions identified in Study 1 would yield significantly lower conviction rates when compared to traditional instructions to disregard in Study 2. The interventions were tested in Study 1 using Multiphase Optimization Strategy (MOST) methodology to identify the optimized intervention package through regression analysis. Study 2 served as a randomized controlled trial in which treatment as usual (a judge’s instructions to disregard) was compared to the optimized intervention package. Participants were randomly assigned to either (1) be exposed to no inadmissible evidence, (2) receive inadmissible evidence and treatment as usual, (3) receive inadmissible evidence, treatment as usual and the optimized intervention package, or (4) receive the inadmissible evidence without objection. Logistic regression revealed that jurors who were given an instruction to disregard produced lower conviction rates when they also received the optimized intervention package. Interpretation, limitations, and calls to action are discussed.
