Time‐of‐day variation of visuo‐spatial attention

Time‐of‐day variation of visuo‐spatial attention in relation to body temperature and subjective arousal was assessed. At five different times of day, alertness, covert, and overt orienting of attention were assessed in fifteen healthy subjects. Based on previous studies reporting a tight coupling of alerting and orienting the present study investigates potential attentional asymmetries induced by diurnal variations of arousal. Both covert and overt orienting of attention improved in the course of the day. However, no asymmetries between left and right visual hemifields could be detected. Covert orienting additionally covaried with body temperature, indicating a quite close relation between the attentional arousal and orienting system. Conversely, overt orienting only improved due to repeated testing but did not correlate with body temperature suggesting a partial independence of both modes of attentional orienting. It can be assumed that due to limited diurnal variations of arousal in the participants and practice effects caused by repeated testing, no attentional asymmetries could be provoked.

Like a camera in the sky? Thinking about God increases public self-awareness and socially desirable responding

Believers describe God as a strategic social agent who perceives human thoughts and actions. Thinking about God therefore might make believers feel as if their behavior is being monitored, a possibility we call the supernatural monitoring hypothesis. Three studies offered new and converging empirical support for this hypothesis using two variables that are sensitive to perceived social surveillance: public self-awareness and socially desirable responding. For believers, the effect of an explicit God prime on public self-awareness was comparable to the effect of thinking about how other people view oneself (Experiment 1). An implicit God concepts prime increased public self-awareness (Experiment 2) and socially desirable responding (Experiment 3) among believers. These studies offer the first direct evidence that thinking of God triggers perceived social surveillance.     

Effects of three training types on vitality among older adults: A self-determination theory perspective

ObjectivesTo investigate effects of endurance, functional and strength training on subjective vitality in older adults. Using the self-determination theory (SDT) framework we tested the moderating effects of autonomy support and mediating effects of need satisfaction on participants’ changes in vitality.DesignParallel-groups randomized controlled trial.Methods138 older adults (M = 74.2 years, SD = 4.5) were randomized to a training group or wait-list control, with assessments at baseline, at 7 weeks (short term), and 16 weeks (long term). Mixed models provided estimates of treatment effects, with covariates for moderating effects of autonomy support and mediating effects of need satisfaction (autonomy, competence, relatedness). Inferences were based on uncertainty in standardized effect-sizes (ES) in relation to a smallest important ES of 0.20.ResultsAt short term, effects on vitality were moderate for endurance training (ES = .70, ±.44), and small for functional (ES = .54, ±.36) and strength training (ES = .21, ±.47). At long term only endurance training had a clear effect on vitality (ES = .27, ±.38). Perceived autonomy support moderated the effect of endurance training at short term (ES = .66, ±.66), and functional training at long term (ES = .23, ±.40). Change in competence mediated the effect of functional and strength training at long term, while in endurance training high perceptions of autonomy support moderated the mediation effect of competence on vitality.ConclusionsEndurance training is recommended for increasing subjective vitality in older adults. Moderating effects of autonomy support and mediating effects of need satisfaction are partially consistent with self-determination theory.

Lifespan aging and belief reasoning: Influences of executive function and social cue decoding

Older adults often perform poorly on Theory of Mind (ToM) tests that require understanding of others’ beliefs and intentions. The course and specificity of age changes in belief reasoning across the adult lifespan is unclear, as is the cause of the age effects. Cognitive and neuropsychological models predict that two types of processing might influence age differences in belief reasoning: executive functioning and social cue detection. In the current study we assessed 129 adults aged between 18 and 86 on novel measures of ToM (video clips and verbal vignettes), which manipulated whether true or false belief reasoning was required. On both video and verbal tasks, older adults (aged 65–88) had specific impairments in false belief reasoning, but showed no such problem in performing true belief tasks. Middle-aged adults (aged 40–64) generally performed as well as the younger adults (aged 18–39). Difficulties in updating information in working memory (but not inhibitory problems) partially mediated the age differences in false belief reasoning. Also, the ability to decode biological motion, indexing social cue detection, partially mediated age-related variance in the ability to interpret false beliefs. These results indicate that age differences in decoding social cues and updating information in memory may be important influences on the specific problems encountered when reasoning about false beliefs in old age.     

Finding the faithless: perceived atheist prevalence reduces anti-atheist prejudice

Although prejudice is typically positively related to relative outgroup size, four studies found converging evidence that perceived atheist prevalence reduces anti-atheist prejudice. Study 1 demonstrated that anti-atheist prejudice among religious believers is reduced in countries in which atheists are especially prevalent. Study 2 demonstrated that perceived atheist prevalence is negatively associated with anti-atheist prejudice. Study 3 demonstrated a causal relationship: Reminders of atheist prevalence reduced explicit distrust of atheists. These results appeared distinct from intergroup contact effects. Study 4 demonstrated that prevalence information decreased implicit atheist distrust. The latter two experiments provide the first evidence that mere prevalence information can reduce prejudice against any outgroup. These findings offer insights about anti-atheist prejudice, a poorly understood phenomenon. Furthermore, they suggest both novel directions for future prejudice research and potential interventions that could reduce a variety of prejudices.     

Assisted versus asserted autonomy satisfaction: Their unique associations with wellbeing,integration of experience,and conflict negotiation

We investigate the possibility of two distinct approaches to autonomy satisfaction—one that is contextually “assisted” and one that is individually “asserted”. Exploratory and confirmatory factor analyses (Pilot Study and Study 1; N = 449) develop and validate the two-factor structure. We then show that asserted and assisted autonomy orientations predict psychological wellbeing through distinct pathways (i.e., highly active/agentic vs. interdependent). In Study 2 (N = 206), we examine the sociodevelopmental antecedents of each type of autonomy satisfaction, revealing that assisted autonomy is associated with having had authoritiative parents, whereas asserted autonomy is associated with having had authoritarian parents. In Study 3 (N = 109) we show that asserted—but not assisted—autonomy predicts the integration of negative life experiences. Finally, in Study 4 (N = 202), we examine the degree to which assisted and asserted autonomy moderate responses to conflict in need-thwarting contexts, showing that assisted autonomy predicts an acquiescent coping style, whereas asserted autonomy predicts an assertive negotiation style.     

Construct Validity of the Balloon Analogue Risk Task (BART): Relationship with MDMA Use by Inner-City Drug Users in Residential Treatment

In a program of research assessing the validity of the balloon analogue risk task (BART; C. W. Lejuez et al., 2002) as a measure of risk taking, the BART was administered to a sample of inner-city drug users in residential treatment (n = 76). Construct validity of the BART was evaluated by measuring risk-taking behavior and 3,4-methylenedioxymethamphetamine (MDMA) use while controlling for self-reported impulsivity, sensation seeking, polysubstance use, and demographic variables. Supporting the construct validity of the BART, while controlling for interrelated variables in the context of logistic regression analyses, (BART) risk-taking propensity accounted for significant incremental variance in differentiating MDMA users from non-users. BART scores, polysubstance use, and younger age were most associated with MDMA use, and together these variables were associated with 91% classification accuracy in predicting MDMA use.
