Hearts Strangely Warmed (and Cooled): Emotional Experience in Religious and Atheistic Individuals

In light of neurophysiological evidence suggesting a link between hemispheric dominance and religious preference, three studies tested whether atheists and religious individuals process emotions differently. Suggestive of right-hemispheric dominance, individuals who identified with religion reported more intense positive emotions associated with a recalled love experience (Study 1), greater sadness in immediate response to reading a tragic news story (Study 2), and more vivid recall of the subjective details of either their most recent birthday or an existential crisis (Study 3). They also reported greater alexithymia compared to atheists. Overall, agnostic/no religion individuals averaged in between these two groups. The results suggest that, relative to atheists, religious individuals have more accessible yet undifferentiated emotions, which may perhaps serve as raw materials for religious experience.     

Beyond Death’s (and Conception’s) Door: The Unsettling Limitations of Incarnate Existence

The psychological effects of contemplating one’s death have received much empirical attention, but the impact of thinking about one’s conception—the other temporal endpoint of physical existence—has not. Across three experiments, reflecting on conception or death (vs. a neutral topic) led to increased framing of sexual reproduction as miraculous and sacred, intensified belief in discarnate immortality, and a greater desire to experience a discarnate state that offered no direct assurance of literal immortality. Thinking about death uniquely evoked greater anxiety as well as greater desire for an experience that offered assurance of literal immortality, congruent with the tenets of terror management theory. Nevertheless, the parallel effects evoked by reflecting on conception and death also suggest that both amplify the aversive salience of the limitations inherent to physical existence, such that people respond by seeking experiences and adjusting attitudes/beliefs to divert attention from the physical body.     

Hate: Evidence for a motivational conceptualization

Quitting before leaving: the mediating effects of psychological attachment and detachment on voice

This research advances understanding of the psychological mechanisms that encourage or dissuade upward, improvement-oriented voice. The authors describe how the loyalty and exit concepts from A. O. Hirschman's (1970) seminal framework reflect an employee's psychological attachment to or detachment from the organization, respectively, and they argue that psychological attachment and detachment should not be considered as separate, alternative options to voice but rather as influences on voice behavior. Findings from 499 managers in the restaurant industry show that psychological detachment (measured as intention to leave) is significantly related to voice and mediates relationships between perceptions of leadership (leader-member exchange and abusive supervision) and voice, whereas psychological attachment (measured as affective commitment) is neither a direct predictor of voice nor a mediator of leadership-voice relationships.     

Discovering New Ways of Moving: Observational Analysis of Motor Creativity While Dancing Contact Improvisation and the Influence of the Partner

Contact improvisation (CI) is a form of dance based on motor creativity, improvisation and the physical contact between different improvisers dancing together. This will generate different ways of moving and a varied use of motor creativity depending on the dancers involved. This study aims to observe the differences in movement generation depending on the partner by using OSMOS (Observational System of Motor Skills; Castañer & Camerino 2006; Castañer et al., 2009). Four contact improvisers were video‐recorded while dancing in duets. Data were analysed by three observers using Theme Coder software (Magnusson, 1996) for the detection of T‐patterns and the production of event frequency charts. The results show that (1) the motor skills that appear most frequently are the conduction of partners, elevations, spatial level changes and turns; (2) motor creativity is affected by the partner, as there is a reciprocal influence in the dance; and (3) motor creativity is enhanced by interaction with a partner.     

Why Dexamethasone Poorly Penetrates in Brain

Dexamethasone poorly penetrates in brain. A tracer amount of [3H]-dexamethasone administered to adrenalectomized rats or mice is poorly retained by glucocorticoid receptors in brain, while pituitary corticotrophs containing equivalent amounts of these receptors accumulate and retain large amounts of this synthetic steroid. However, adrenalectomized mice with a genetic disruption of the multiple drug resistance (mrd1a) gene have a tenfold increase of [3H]-dexamethasone uptake in brain glucocorticoid target sites reaching levels observed in the pituitary. These data demonstrate that dexamethasone is extruded from brain by the mrd1a-encoded P-glycoproteins. The data support the concept of a pituitary site of action of dexamethasone in blockade of stress-induced ACTH release, which implies that chronic dexamethasone treatment does not replace the endogenous corticosteroids depleted from brain mineralocorticoid (MRs) and glucocorticoid receptors (GRs). Dexamethasone, therefore, causes a profound disturbance in the balance of these two receptor types in hippocampus, which is an unfavourable condition threatening the neuronal integrity of this brain structure through the expression of noxious genes.     

Dexamethasone Does Not Prevent Seven-Day ADX-Induced Apoptosis in the Dentate Gyrus of the Rat Hippocampus

Long-term adrenalectomy (ADX) is known to result in apoptosis within the dentate gyrus of the rat hippocampus. While the underlying mechanism is still unclear, adrenal steroids appear to play a pivotal role in granule cell survival, as administration of the mineralocorticoid receptor (MR) agonists, corticosterone and aldosterone, to ADX rats results in protection against the ADX-induced effect. The consequence of administration of the glucocorticoid receptor (GR) agonists, dexamethasone and RU28362, however, is less clear, and either complete or only partial protection for the ADX animal has been reported. This study investigated further the role played by GR in the degenerative process. After establishing the characteristics of seven-day ADX-induced apoptosis in the young male Wistar rat, the effect of chronically-implanted, subcutaneous pellets containing various doses of dexamethasone and corticosterone, on ADX-induced apoptosis was studied. Both high and low doses of corticosterone were found to be protective. In contrast to some other studies, however, neither dose of dexamethasone had any obvious protective effect and rather seemed to increase apoptosis in dentate gyrus of intact animals. Intracerebroventricular infusion of dexamethasone for seven days was also found to be ineffective in preventing apoptosis, demonstrating that it is occupation of MR, rather than GR, which is crucial to dentate gyrus granule cell survival.     

Racism,Counterfactual Thinking,and Judgment Severity1

Two contrasting models of the effects of motivational influences on the relationship between counterfactual thinking and social judgment were tested, using a modified version of Wells and Gavanski's (1989) cab driver vignette. Undergraduates (N= 208) assigned blame to a negligent white or black target after imagining how the target's alternative behavior could have either easily or improbably averted two accident-related fatalities. Results suggested that motivational variables such as racism moderate the relationship between counterfactual thinking and judgment severity rather than directly affect the counterfactual thinking process itself. Implications for current conceptions of both counterfactual thinking and racism are discussed.     

Distorted distance estimation induced by a self-relevant national boundary

Six experiments explored the possibility that the categorization of self versus not-self can distort visual estimations of distance. In Experiments 1-3, Americans overestimated the distance between a U.S. location and a foreign location relative to a visually equidistant U.S. location. In Experiment 4, Canadians overestimated foreign relative to Canadian locations. Experiment 5 showed that this effect occurs even when the domestic context is not physically contiguous. Experiment 6 showed that distance distortion occurs only when crossing one’s own border to a foreign location, not when crossing borders from one foreign location to another. Thus, crossing the psychological boundary between self and not-self creates a visual illusion that distorts on-line distance estimates.
