Influence of instruction on velocity and accuracy of overarm throwing

This study investigated the influence of instruction on the ball velocity and accuracy of a goal-directed overarm throw. 9 experienced Norwegian male team handball players executed a throwing task randomly seven times under 5 different instructions varying from emphasizing speed to accuracy. When instructions increasingly emphasized accuracy, velocity decreased. However, accuracy did not improve when subjects were instructed to focus on it. A possible explanation for this finding could lie in the specific subject group. The subjects were highly experienced team handball players with an average of 12 years in the sport. Thus, the accuracy they demonstrated at high velocity might actually be already extremely high and difficult to improve upon when reducing throwing velocity. Further, the velocity of throwing when instruction emphasized accuracy was approximately 85% of the maximal velocity, indicating that experienced team handball players are trained to throw accurately at relatively high velocity.     

It does take a village: nonfamilial environments and children's behavior

Abstract - Family characteristics influence children's behavioral development, but so do variations in schools, neighborhoods, and communities. We documented extrafamilial environmental effects by fitting maximum likelihood models to questionnaire data collected from double dyads consisting of twins and their classmate controls. The classmate controls in each double dyad were genetic strangers living in separate households, but they shared school, neighborhood, and community environments with their yoked twin pair and with one another. At ages 11 to 12, the control classmates showed significant similarities in religious practices and smoking and drinking patterns, demonstrating that environmental influences outside the family affect children's behavioral development. Familial self-selection of residential neighborhoods may have contributed to these results, but direct effects of variation across communities, neighborhoods, and schools cannot be dismissed, and such effects warrant further study.     

Neuroticism and extraversion are associated with amygdala resting-state functional connectivity

The personality traits neuroticism and extraversion are differentially related to socioemotional functioning and susceptibility to affective disorders. However, the neurobiology underlying this differential relationship is still poorly understood. This discrepancy could perhaps best be studied by adopting a brain connectivity approach. Whereas the amygdala has repeatedly been linked to neuroticism and extraversion, no study has yet focused on the intrinsic functional architecture of amygdala-centered networks in relation to both traits. To this end, seed-based correlation analysis was employed to reveal amygdala resting-state functional connectivity (RSFC) and its associations with neuroticism and extraversion in 50 healthy participants. Higher neuroticism scores were associated with increased amygdala RSFC with the precuneus, and decreased amygdala RSFC with the temporal poles, insula, and superior temporal gyrus (p < .05, cluster corrected). Conversely, higher extraversion scores were associated with increased amygdala RSFC with the putamen, temporal pole, insula, and several regions of the occipital cortex (p < .05, cluster corrected). The shifts in amygdala RSFC associated with neuroticism may relate to the less-adaptive perception and processing of self-relevant and socioemotional information that is frequently seen in neurotic individuals, whereas the amygdala RSFC pattern associated with extraversion may relate to the heightened reward sensitivity and enhanced socioemotional functioning in extraverts. We hypothesize that the variability in amygdala RSFC observed in the present study could potentially link neuroticism and extraversion to the neurobiology underlying increased susceptibility or resilience to affective disorders.     

Religious polarization: contesting religion in secularized Western European countries

In light of recent claims about increasing religious polarization in secularized countries, we study the extent to which the non-religious contest religion in Western European countries and whether and how the Protestant and Catholic heritage of these countries plays a role in this. Analyzing data from the International Social Survey Program (ISSP 1998 and 2008) data by means of multilevel analysis, we demonstrate that religious polarization is stronger in the most secularized countries and in countries with a Catholic religious heritage. Moreover, in secular countries, polarization stems from religious fervency, whereas in countries with a Catholic heritage, it stems from anti-religious fervency.     

The naked truth: mindfulness and the purification of religion

To arrive at an understanding of what drives the much debated spiritual turn in Western Europe, we study the spiritual trajectories and identifications of mindfulness practitioners in the formerly predominantly Roman Catholic context of Flanders in Belgium. Fifteen semi-structured interviews addressed their religious and spiritual biographical trajectories as well as the symbolic boundaries they draw with adjacent religious and spiritual groups. We find marked evidence of a process of ‘religious purification’, which unfolds as a critique of the formal and external aspects of both religion (organisations, dogmas, ritual) and spirituality (woolly and frivolous New Age word games). To validate and justify, alternatively, the ‘pure’ and ‘grounded’ spirituality that results, those concerned consistently invoke the authority of science.     

‘Of the group’ and ‘for the group’: How followership is shaped by leaders' prototypicality and group identification

Previous research has focused on the importance of leaders being seen to be of the group (i.e. to be prototypical of a group) but less on the impact of leaders' own degree of identification with the group. Also, little is known about the combined impact of leader prototypicality and leader identification on followers' responses. This paper reports two studies that address these lacunae. Study 1 shows experimentally that perceived leader identification and prototypicality interact to determine followers' personal identification with leaders and their perceptions of leader charisma. Findings indicate that high identification can compensate for low prototypicality such that high‐identified leaders are able to inspire followership when leaders are low prototypical. Study 2 replicates these findings in the field by examining followers' responses to workgroup leaders. In addition, results demonstrate that the aforementioned responses are more pronounced for highly identified followers. The present research extends social identity theorizing by demonstrating that leaders' inability to inspire followership derives as much from their failure to project a sense of ‘we’ and ‘us’ as part of their self‐concept as from a failure to exemplify group‐typical attributes.

Hypertension reduction through forgiveness training

The objective of this study was to determine if patients with diagnosed stage-1 hypertension could benefit by a forgiveness training program to achieve measurable reductions in anger expression and blood pressure. Twenty-five participants were randomly divided into wait-listed control and intervention groups. The control group monitored blood pressure while the intervention group participated in an 8-week forgiveness training program. At the end of eight weeks, the wait listed group became an intervention group. Those who received forgiveness training achieved significant reductions in anger expression when compared to the control group. While reductions in blood pressure were not achieved by all the participants, those participants who entered the program with elevated anger expression scores did achieve significant reductions in blood pressure. It is suggested that forgiveness training may be an effective clinical intervention for some hypertensive patients with elevated levels of anger.     

Proximal antecedents and correlates of adopted error approach: a self-regulatory perspective

The current study aims to further investigate earlier established advantages of an error mastery approach over an error aversion approach. The two main purposes of the study relate to (1) self-regulatory traits (i.e., goal orientation and action-state orientation) that may predict which error approach (mastery or aversion) is adopted, and (2) proximal, psychological processes (i.e., self-focused attention and failure attribution) that relate to adopted error approach. In the current study participants' goal orientation and action-state orientation were assessed, after which they worked on an error-prone task. Results show that learning goal orientation related to error mastery, while state orientation related to error aversion. Under a mastery approach, error occurrence did not result in cognitive resources "wasted" on self-consciousness. Rather, attention went to internal-unstable, thus controllable, improvement oriented causes of error. Participants that had adopted an aversion approach, in contrast, experienced heightened self-consciousness and attributed failure to internal-stable or external causes. These results imply that when working on an error-prone task, people should be stimulated to take on a mastery rather than an aversion approach towards errors.     

Religiosity for Promotion of Behaviors Likely to Reduce New HIV Infections in Uganda: A Study Among Muslim Youth in Wakiso District

The study was done to determine the association between religiosity and behaviors likely to reduce new HIV infections among 1,224 Muslim youth. Respondents with Sujda, the hyperpigmented spot on the forehead due to prostration during prayers, were more likely to abstain from sex, be faithful in marriage, and avoid alcohol and narcotics. Males wearing a Muslim cap were more likely to abstain from sex and avoid alcohol and narcotics. Females wearing the long dress (Hijab) were also more likely to avoid alcohol. This data should be used by stakeholders in promoting behaviors likely to reduce new HIV infections among Muslims.     

Understanding and Assisting Couples Affected by an Eating Disorder

This article reviews the existing literature on heterosexual intimate relationships in which the female partner has an eating disorder. These couples often have trouble in a number of areas, including communication, sexual functioning, relational boundaries, and emotional health. Not only do these problems contribute to lower rates of relational satisfaction but they also affect a woman's chances for recovery. An understanding of this literature can inform family therapy practice. Recommendations are offered for those who provide counseling to these couples.
