Linking Family-of-Origin Experiences and Perpetration of Sexual Coercion: College Males’ Sense of Entitlement

Sexual coercion on college campuses has become of major concern in recent decades. In recent years, researchers and policy makers have called for greater attention to this topic in order to reduce the sexual violence on college campuses. Recent research has examined the impact of family-of-origin experiences on the perpetration of sexual coercion. The current study examines the association between family-of-origin experiences, such as warmth and hostility between parents, inconsistent parenting, and overparenting during childhood, and the perpetration of sexual coercion among emerging adult males while examining feelings of entitlement as a possible mediator. Data from 326 male undergraduate students were analyzed using structural equation modeling. Results show that warmth and hostility between parents has a significant association with parenting behaviors (i.e., overparenting and inconsistent parenting) and that hostility between parents is associated with the perpetration of sexual coercion by the offspring in young adulthood for males. Also, findings suggest that while overparenting and inconsistent parenting during childhood are not directly associated with the perpetration of sexual coercion during emerging adulthood, they are strongly related to feelings of entitlement, which in turn was found to be associated with the perpetration of sexual coercion for males. These results have important implications for family life education, including relationship and parenting education, and for future research.     

Relationship Contexts as Sources of Socialization: An Exploration of Intimate Partner Violence Experiences of Economically Disadvantaged African American Adolescents

Intimate partner violence (IPV) among African Americans is a serious public health concern. Research suggest that African Americans adolescents, particularly those from economically disadvantaged communities, are at heightened risk for experiencing and perpetrating dating violence compared to youth from other racial and ethnic groups. In the present study, we examined different relationship contexts that are sources of IPV socialization. Semi-structured interviews were conducted with 22 economically disadvantaged African American adolescents. Content analysis yielded five relationship contexts through which the participants witnessed, experienced, and perpetrated IPV: (a) adolescents’ own dating relationships (64%), (b) siblings and extended family members (e.g., cousins, aunts, uncles) (59%), (c) parent-partners (27%), (d) friends (23%), and (e) neighbors (18%). Adolescents also frequently described IPV in their own dating relationships and in parent-partner relationships as mutual. Moreover, they appeared to minimize the experience of IPV in their own relationships. Efforts to reduce rates of IPV among economically disadvantaged African American adolescents should consider these relational contexts through which adolescents are socialized with regards to IPV and adolescents’ beliefs about mutual violence in relationships. Results highlight the importance of culturally relevant prevention and intervention programs that consider these relationship contexts.     

Sleep deprivation selectively impairs memory consolidation for contextual fear conditioning

Many behavioral and electrophysiological studies in animals and humans have suggested that sleep and circadian rhythms influence memory consolidation. In rodents, hippocampus-dependent memory may be particularly sensitive to sleep deprivation after training, as spatial memory in the Morris water maze is impaired by rapid eye movement sleep deprivation following training. Spatial learning in the Morris water maze, however, requires multiple training trials and performance, as measured by time to reach the hidden platform is influenced by not only spatial learning but also procedural learning. To determine if sleep is important for the consolidation of a single-trial, hippocampus-dependent task, we sleep deprived animals for 0–5 and 5–10 h after training for contextual and cued fear conditioning. We found that sleep deprivation from 0–5 h after training for this task impaired memory consolidation for contextual fear conditioning whereas sleep deprivation from 5–10 h after training had no effect. Sleep deprivation at either time point had no effect on cued fear conditioning, a hippocampus-independent task. Previous studies have determined that memory consolidation for fear conditioning is impaired when protein kinase A and protein synthesis inhibitors are administered at the same time as when sleep deprivation is effective, suggesting that sleep deprivation may act by modifying these molecular mechanisms of memory storage.     

Covariation neglect among novice investors

In 4 experiments, undergraduates made hypothetical investment choices. In Experiment 1, participants paid more attention to the volatility of individual assets than to the volatility of aggregated portfolios. The results of Experiment 2 show that most participants diversified even when this increased risk because of covariation between the returns of individual assets. In Experiment 3, nearly half of those who seemingly attempted to minimize risk diversified even when this increased risk. These results indicate that novice investors neglect covariation when diversifying across investment alternatives. Experiment 4 established that naive diversification follows from motivation to minimize risk and showed that covariation neglect was not significantly reduced by informing participants about how covariation affects portfolio risk but was reduced by making participants systematically calculate aggregate returns for diversified portfolios. In order to counteract naive diversification, novice investors need to be better informed about the rationale underlying recommendations to diversify.     

Gender,Employment Status,and Abortion: A Longitudinal Analysis

Building upon extant literature, we examine the influence gender and employment status exert on abortion attitudes among the mass public. Specifically, we assess if men, employed women, and homemaker women view the abortion issue differently and if the same factors account for variation in each group's attitudes toward abortion. Analysis of General Social Survey data from 1973 to 2000 indicates that although homemaker women tend to be more pro-life than do men or working women, the attitudes of all 3 groups exhibit similar changes over time. In addition, our results suggest that the same variables account for variation in abortion attitudes for all 3 groups. Our results suggest that the causes and effects of abortion attitudes do not appear to be gender-specific, but rather are relatively uniform across genders and employment statuses.
