Development of lateral asymmetry in the perception of sequentially touched fingers

In order to investigate lateral asymmetry in tactile perception, two or four fingers of normal primary school children were touched sequentially. Stimulation was either unimanual or bimanual and either verbal or nonverbal responses were required. Right hand advantage was demonstrated subsequent to uni- and bimanual stimulation in both the verbal and nonverbal response conditions. Neither an age nor a sex effect on laterality was found. Right hand advantage was affected by direction of stimulation in the bimanual condition. Left hemispheric dominance was argued to be related to the temporal nature of the tasks.     

Proactive Vitality Management,Work Engagement,and Creativity: The Role of Goal Orientation

This study tested the hypothesis that individuals can proactively manage their own energetic, affective, and cognitive resources in order to be creative at work. Building on proactivity and creativity literatures, we propose a theoretical model in which employees who proactively manage their vitality are more engaged in their work and show improved creative performance. We also tested the boundary conditions of this process. Participants were Dutch employees from various occupations who filled out a background questionnaire and five weekly surveys. The results of multilevel modelling analyses offered support for our model. Weekly proactive vitality management was positively related to changes in weekly creativity through changes in weekly work engagement. As predicted, learning goal orientation strengthened and performance goal orientation weakened the links between proactive vitality management and engagement, and between engagement and creativity. We discuss the theoretical contributions, and indicate how these findings can be used in daily working life.     

Daily self-management and employee work engagement

The present study adopts a bottom-up approach to work engagement by examining how self-management is related to employees' work engagement on a daily basis. Specifically, we hypothesized that on days that employees use more self-management strategies, they report higher resources at work and in turn, are more vigorous, dedicated, and absorbed in their work (i.e., engaged) on these days. We tested this hypothesis in a sample of 72 maternity nurses who filled out an online diary for 5 days (N = 360 data points). In line with our hypotheses, results of multilevel structural equation modeling analyses showed that daily self-management was positively related to the resourcefulness of the daily work environment (i.e., more skill variety, feedback, and developmental opportunities) and consequently, to employees' daily work engagement. However, contrary to our expectations, the measurement model showed that two of the five included self-management strategies (i.e., self-reward and self-punishment) loaded onto a separate factor and were unrelated to all job resources. The findings contribute to our understanding of employees' role in regulating their own daily work engagement.     

Personality Traits,Income, and Economic Ideology

While the psychological underpinnings of social ideology are well established, less is known about the psychological underpinnings of economic ideology. In this study, I assess whether Big Five personality traits are associated with economic ideology and when personality traits are more strongly or more weakly associated with economic ideology. I hypothesize that low income attenuates the association between the Big Five traits and economic ideology. Studies conducted in Denmark, the United Kingdom, and the United States show that Conscientiousness is positively correlated with economic conservatism, while Agreeableness and Neuroticism are negatively correlated with economic conservatism. Moreover, low income attenuates the association between personality traits and economic ideology. I report a weaker association between Agreeableness and economic ideology among poor people compared to wealthier people in all three countries. Low income also attenuates the association between economic ideology and the traits Openness (Denmark), Extraversion (United Kingdom), and Neuroticism (United States). I contribute to the literature addressing the psychological correlates of economic ideology by showing that (1) economic ideology has a distinct set of personality correlates and (2) low income attenuates the association between some personality traits and economic ideology.     

Shedding some light on catching in the dark: perceptual mechanisms for catching fly balls

To catch a lofted ball, a catcher must pick up information that guides locomotion to where the ball will land. The acceleration of tangent of the elevation angle of the ball (AT) has received empirical support as a possible source of this information. Little, however, has been said about how the information is detected. Do catchers fixate on a stationary point, or do they track the ball with their gaze? Experiment 1 revealed that catchers use eye and head movements to track the ball. This means that if AT is picked up retinally, it must be done by means of background motion. Alternatively, AT could be picked up by extraretinal mechanisms, such as the vestibular and proprioceptive systems. In Experiment 2, catchers reliably ran to intercept luminous fly balls in the dark, that is, in absence of a visual background, under both binocular and monocular viewing conditions. This indicates that the optical information is not detected by a retinal mechanism alone.     

Reciprocal relations between recovery and work engagement: the moderating role of job stressors

In this paper, we examined the within-person relations between morning recovery level (i.e., feeling refreshed and replenished) and work engagement throughout the day, and between work engagement throughout the day and the subsequent recovery level at the end of the workday. We hypothesized that job stressors (situational constraints, job demands) moderate these relations. A diary study over 1 workweek with 2 measurement occasions per day (N = 111 persons) provided support for most of the hypotheses: Morning recovery level predicted work engagement, and work engagement predicted subsequent recovery level at the end of the workday after controlling for morning recovery level. As predicted, situational constraints attenuated these relations, but job demands did not. The results suggest that recovery translates into employee work engagement, and work engagement, in turn, prevents a loss in recovery level throughout the day, particularly when situational constraints are low. Situational constraints seem to interrupt the reciprocal processes between recovery level and work engagement.
