Religion and the decision to donate organs: Exploring the potential role of religious leaders

The two‐step flow model of communication (Katz, 1957 ) suggests opinion leaders obtain critical information from the mass media and, in turn, communicate this information to interpersonal contacts such as friends, family and co‐workers. It is suggested that religious leaders (RLs) may serve as opinion leaders on the topic of organ donation by debunking donation myths, promoting donation during worship services, or communicating the benefit of donation to families faced with the opportunity to participate in living or cadaveric donation. The current study examined the personal knowledge, experiences, and willingness to communicate about organ donation in a sample of RLs (N = 59) in Rochester, New York. Structured interviews were conducted in summer and fall of 2009 with a random sample of RLs. Results indicate a disparity between RLs' expressed personal support for donation and their engagement in donor registration. Approximately one‐quarter of RLs have spoken about donation during a religious service and many indicate their knowledge is not sufficient to discuss organ donation in detail. Results elaborate on how RLs may be trained to serve as opinion leaders in the promotion of organ donation. Copyright © 2010 John Wiley & Sons, Ltd.     

Rumination partially mediates the associations between perceived ethnic discrimination, emotional distress, and aggression

Research suggests that perceived ethnic discrimination is associated with poor psychological and physiological health. Rumination, or perseverative thoughts about negative experiences, may constitute a maladaptive coping strategy that mediates the associations between perceived discrimination, emotional distress, and aggression. Our sample consisted of 170 ethnic minority and 134 White American participants. For ethnic minority participants, we found a pattern of correlations consistent with rumination partially mediating a causal link between perceived discrimination and depressive symptoms, hostility, anger, and aggression. In White participants, by contrast, the significant associations between perceived discrimination and these indices of emotional and behavioral distress were not statistically mediated by rumination. We discuss possible theoretical and clinical implications of these results.     

Predicting ideal body mass index: what does clothing size have to do with it?

This study examined demographic and anthropometric variables as predictors of ideal body mass index (BMI) from cross-sectional, archival, self-reported data from the Psychology of Size Survey of 4014 U.S. residents collected in 2007. As hypothesized, ideal BMI can be predicted by a within gender hierarchical multiple regression analysis with the predictor variables of age, number of clothing sizes from ideal size, and current BMI; these variables account for 54.1% of variance in women's ideal BMI and 65.5% of variance in men's ideal BMI. Findings also demonstrated a logarithmic relationship between current BMI and ideal BMI, with increasing variance in ideal BMI for individuals with high current BMIs. These findings evidence the strong role of current body characteristics in the formation of ideals. Understanding how individuals conceptualize body ideals can inform researchers and practitioners alike, as this evidence has important implications related to both medical and psychological health.     

Longitudinal stability of temperamental exuberance and social-emotional outcomes in early childhood

The goals of the current study were to investigate the stability of temperamental exuberance across infancy and toddlerhood and to examine the associations between exuberance and social-emotional outcomes in early childhood. The sample consisted of 291 4-month-olds followed at 9, 24, and 36 months and again at 5 years of age. Behavioral measures of exuberance were collected at 9, 24, and 36 months. At 36 months, frontal electroencephalogram (EEG) asymmetry was assessed. At 5 years, maternal reports of temperament and behavior problems were collected, as were observational measures of social behavior during an interaction with an unfamiliar peer in the laboratory. Latent profile analysis revealed a high, stable exuberance profile that was associated with greater ratings of 5-year externalizing behavior and surgency, as well as observed disruptive behavior and social competence with unfamiliar peers. These associations were particularly true for children who displayed left frontal EEG asymmetry. Multiple factors supported an approach bias for exuberant temperament but did not differentiate between adaptive and maladaptive social-emotional outcomes at 5 years of age.     

Here’s Looking at You: Self-Objectification, Body Image Disturbance, and Sorority Rush

This study investigated the impact of sorority rush on self-objectification and body image disturbance. First-year undergraduate women either participating (n?=?68) or not participating (n?=?59) in sorority rush at a U.S. Midwestern university completed online surveys at four time points. It was predicted that rush participation would lead to increases in self-objectification, which in turn would lead to increases in body shame and eating disordered behavior and attitudes. Results supported predictions based on objectification theory at a single time point, but not longitudinally. Rush participants evidenced higher levels of self-objectification and eating disordered behavior at all time points. Body mass index predicted dropping out of the rush process and was negatively correlated with satisfaction with the rush process.     

Localized disruption of Narp in medial prefrontal cortex blocks reinforcer devaluation performance

Neuronal activity regulated pentraxin (Narp) is a secreted protein that regulates α-amino-3-hydroxyl-5-methyl-4-isoxazole-propionate receptors (AMPAR) aggregation and synaptogenesis. Mapping of Narp-positive neurons in brain has revealed it is prominently expressed in several limbic system projection pathways. Consistent with this localization pattern, Narp knockout mice show deficits in using the current value of a reinforcer to guide behavior, a critical function of the limbic system. To help assess whether this behavioral deficit is due to impairment of synaptogenesis during development or in modulating synaptic signaling in the mature brain, we have used a dominant negative Narp viral construct which blocks trafficking of endogenous Narp to axons. Focal injection of this viral construct into the medial prefrontal cortex (mPFC) of adult mice, a region containing Narp-positive projection neurons, blocked reinforcer devaluation. Thus, these results indicate that Narp released from mPFC neurons plays a key role in mediating synaptic changes underlying instrumental reinforcer devaluation.     

Effects of Kindermusik training on infants’ rhythmic enculturation

Phillips‐Silver and Trainor (2005) demonstrated a link between movement and the metrical interpretation of rhythm patterns in 7‐month‐old infants. Infants bounced on every second beat of a rhythmic pattern with no auditory accents later preferred to listen to an accented version of the pattern with accents every second beat (duple or march meter), whereas infants bounced on every third beat of the same rhythmic pattern preferred to listen to a version with accents every third beat (triple or waltz meter). The present study compared infants participating in Kindermusik classes with infants not participating in music classes. In Kindermusik classes infants receive enriched experience moving to music. Following Western musical norms, the majority of the music samples in the classes are in duple meter. During the preference test, Kindermusik infants listened longer overall, indicating heightened interest in musical rhythms. Both groups listened longer to the accented version that matched how they had been bounced, but only the Kindermusik group showed a stronger preference in the case of duple bouncing than in the case of triple bouncing. We conclude that musical classes for infants can accelerate the development of culture‐specific metrical perception.     

The Caregiver Eating Messages Scale: Development and psychometric investigation

Certain caregiver eating messages – restriction of food intake and pressures to eat – are associated with body dissatisfaction and eating disturbances among young girls. This study explored whether these messages are also associated with body attitudes and eating behaviors of young adult women and men. The Caregiver Eating Messages Scale was developed to measure this construct. Two studies (Ns = 238, 288) indicated that it contained two factors (restrictive/critical messages and pressure to eat messages) and yielded internally consistent, stable, and valid scores. Both factors were positively related to women's BMI, and restrictive/critical messages were positively related to men's BMI. Restrictive/critical messages predicted lower perceived familial body acceptance and intuitive eating and higher perceived familial pressure to be lean and disordered eating. Restrictive/critical messages predicted participants’ body attitudes indirectly via their perceptions of their family's attitude toward their body, with one exception: restrictive/critical messages uniquely predicted men's body appreciation.     

Effects of Ingroup Bias and Gender Role Violations on Acquaintance Rape Attributions

Two studies of ethnically diverse US college students from northern California examined whether ingroup bias and gender norm violations influence acquaintance rape attributions (Study 1, N?=?118; Study 2, N?=?140). Participants read vignettes depicting acquaintance rape and completed questionnaires. Victims were part of participants’ ingroup or outgroup. Study 1 manipulated the victim’s sexual history (chaste or promiscuous). Study 2 manipulated the victim’s alcohol use (sober or intoxicated). Ingroup victims were perceived more positively than outgroup victims if the victims were promiscuous or intoxicated. More guilt was attributed to rapists of ingroup victims than outgroup victims if the victims were promiscuous or intoxicated. Findings are examined in relation to ingroup bias and gender norm violations.     

Academic Achievement Over 8 Years Among Children Who Met Modified Criteria for Attention-deficit/Hyperactivity Disorder at 4–6 Years of Age

The predictive validity of symptom criteria for different subtypes of ADHD among children who were impaired in at least one setting in early childhood was examined. Academic achievement was assessed seven times over 8 years in 125 children who met symptom criteria for ADHD at 4–6 years of age and in 130 demographically-matched non-referred comparison children. When intelligence and other confounds were controlled, children who met modified criteria for the predominantly inattentive subtype of ADHD in wave 1 had lower reading, spelling, and mathematics scores over time than both comparison children and children who met modified criteria for the other subtypes of ADHD. In some analyses, children who met modified criteria for the combined type had somewhat lower mathematics scores than comparison children. The robust academic deficits relative to intelligence in the inattentive group in this age range suggest either that inattention results in academic underachievement or that some children in the inattentive group have learning disabilities that cause secondary symptoms of inattention. Unexpectedly, wave 1 internalizing (anxiety and depression) symptoms independently predicted deficits in academic achievement controlling ADHD, intelligence, and other predictors.
