The Gods Are Watching: An Experimental Study of Religion and Traditional Belief in Burkina Faso

Traditional beliefs play an important role in many Sub‐Saharan African village societies. These beliefs imply immediate punishment for any breach of the moral code, and the possibility to influence an individual's life by the use of magic. We analyze the economic impact of traditional beliefs on behavior by conducting an experiment with microentrepreneurs in the environs of Ouagadougou (Burkina Faso). The salience of traditional beliefs is randomly varied through semistructured interviews. We find that priming traditional beliefs substantially increases prosocial behavior in the Trust Game. This effect is independent of age, gender, religious affiliation, or wealth.     

Spearman’s Law of Diminishing Returns and national ability

This research examined Spearman’s Law of Diminishing Returns (SLODR) using national ability as the unit of analysis. National ability was estimated using international standardized tests such as the Programme for International Student Assessment (PISA), Trends in International Mathematics and Science Study (TIMSS), and Progress in International Reading Literacy Study (PIRLS). Factor analysis estimated the national G loadings of tests for high and low ability nations. Consistent with SLODR, the G loadings of tests were lower for higher ability nations. The pattern was confirmed after correcting for school attendance and age biases. Because a test’s g loading is directly related to its predictive validity (correlation with outcomes), our results imply that the predictive validity of tests may be lower for higher ability nations.     

Testing and validating the trait emotional intelligence questionnaire (TEIQue) in a German-speaking sample

The trait emotional intelligence questionnaire (TEIQue) was tested and validated using a sample of 352 German-speaking participants. A detailed psychometric analysis provided evidence in support of the reliability of the TEIQue (at the facet, factor and global levels) and the robustness of its proposed four-factor structure. Using a subsample of 150 participants, the associations between the TEIQue and a series of relevant constructs (Big Five, life satisfaction, somatic complaints) were examined, which also included data on other trait EI measures. Overall, the TEIQue showed theoretically expected relationships to all other constructs and incremental validity in the prediction of life satisfaction and somatic complaints over and above the Big Five as well as all other trait EI measures combined.     

Psychosis and multiple family group therapy

Despite the growing evidence base for the effectiveness of family intervention in the treatment of individuals suffering from a psychotic disorder, in practice only relatively few mental health teams use family approaches when treating and managing those with schizophrenia or other psychoses. This paper describes a pragmatic model, which may be used in addition to other ongoing treatments, such as medication, CBT or single family therapy. It was developed jointly by clinicians and service users over the past few years. It consists of regular multiple family group work, with six to eight families attending simultaneously, and aims to involve families directly in the treatment, rehabilitation and recovery of their members suffering from psychotic disorder.     

Life Satisfaction from Late Adolescence to Mid-Life The Impact of Life Success and Success Evaluation on the Life Satisfaction of Former Gymnasium Students Between Ages 30 And 43

In order to be satisfied with one's life, one has to adapt goals to opportunities; from this, two hypotheses follow: Life satisfaction should be more strongly determined by success evaluation rather than life success, and more strongly by late rather than early life success. Both hypotheses are examined in a longitudinal study of former Gymnasium students from age 16 to 43.Dependent variables are the satisfaction with occupational and with private life at age 43. Independent variables are life success in occupational and private life between ages 16 and 43, satisfaction with occupational and private life at age 30, and strategies of coping with and attributing of success at age 43. As hypothesized, satisfaction with occupational and with private life are determined more strongly by success evaluation rather than by life success and by late rather than early life success. Furthermore, occupational satisfaction is more strongly determined by the former occupational career than private satisfaction by the private career.     

Attention and suppression affect tactile perception in reach-to-grasp movements

Reaching with the hand is characterized by a decrease in sensitivity to tactile stimuli presented to the moving hand. Here, we investigated whether tactile suppression can be canceled by attentional orienting. In a first experiment, participants performed a dual-task involving a goal-directed movement paired with the speeded detection of a tactile pulse. The pulse was either delivered to the moving or stationary hand, during movement preparation, execution, or the post-movement phase. Furthermore, stimulation was delivered with equal probability to either hand, or with a higher probability to either the moving or resting hand. The results highlighted faster RTs under conditions of higher probability of stimulation delivery to both moving and resting hands, thus indicating an attentional effect. For the motor preparation period, RTs were faster only at the resting hand under conditions where tactile stimulation was more likely to be delivered there. In a second experiment, a non-speeded perceptual task was used as a secondary task and tactile discrimination thresholds were recorded. Tactile stimulation was delivered concomitantly at both index fingers either in the movement preparation period (both before and after the selection of the movement effector had taken place), in the motor execution period, or, in a control condition, in the time-window of motor execution, but the movement of the hand was restrained. In the preparation period, tactile thresholds were comparable for the two timings of stimulation delivery; i.e., before and after the selection of the movement effector had taken place. These results therefore suggest that shortly prior to, and during, the execution of goal-directed movements, a combined facilitatory and inhibitory influence acts on tactile perception.
