Does the walking task matter? Influence of different walking conditions on dual-task performances in young and older persons

Previous literature suggests that age-related deficits of dual-task walking are particularly pronounced with second tasks that require continuous visual processing. Here we evaluate whether the difficulty of the walking task matters as well. To this end, participants were asked to walk along a straight pathway of 20 m length in four different walking conditions: (a) wide path and preferred pace; (b) narrow path and preferred pace, (c) wide path and fast pace, (d) obstacled wide path and preferred pace. Each condition was performed concurrently with a task requiring visual processing or fine motor control, and all tasks were also performed alone which allowed us to calculate the dual-task costs (DTC). Results showed that the age-related increase of DTC is substantially larger with the visually demanding than with the motor-demanding task, more so when walking on a narrow or obstacled path. We attribute these observations to the fact that visual scanning of the environment becomes more crucial when walking in difficult terrains: the higher visual demand of those conditions accentuates the age-related deficits in coordinating them with a visual non-walking task.     

Indirect scaling methods for testing quantitative emotion theories

Two studies investigated the utility of indirect scaling methods, based on graded pair comparisons, for the testing of quantitative emotion theories. In Study 1, we measured the intensity of relief and disappointment caused by lottery outcomes, and in Study 2, the intensity of disgust evoked by pictures, using both direct intensity ratings and graded pair comparisons. The stimuli were systematically constructed to reflect variables expected to influence the intensity of the emotions according to theoretical models of relief/disappointment and disgust, respectively. Two probabilistic scaling methods were used to estimate scale values from the pair comparison judgements: Additive functional measurement (AFM) and maximum likelihood difference scaling (MLDS). The emotion models were fitted to the direct and indirect intensity measurements using nonlinear regression (Study 1) and analysis of variance (Study 2). Both studies found substantially improved fits of the emotion models for the indirectly determined emotion intensities, with their advantage being evident particularly at the level of individual participants. The results suggest that indirect scaling methods yield more precise measurements of emotion intensity than rating scales and thereby provide stronger tests of emotion theories in general and quantitative emotion theories in particular.     

Creative Thinking in Adolescents with Attention Deficit Hyperactivity Disorder (ADHD)

A widened attentional focus, that is typically associated with ADHD, has been postulated to be accompanied by enhanced creative ability. However, creativity has been only limitedly examined in ADHD. Performance across several creativity measures were investigated in three groups: adolescents with ADHD, those with conduct disorder, and a healthy control sample. The ADHD group exhibited selective cognitive advantages and disadvantages by demonstrating an enhanced ability in overcoming the constraining influence of examples, but a reduced capacity to generate a functional invention during an imagery task. These findings are interpreted with reference to inhibitory control mechanisms and the contextual modulation of creative cognition.     

Goal engagement in coping with occupational uncertainty predicts favorable career-related outcomes

We investigated whether goal engagement and disengagement in coping with occupational uncertainty (e.g., perceptions of growing difficulties in career planning and lacking job opportunities) predicts three objective career-related outcomes: job loss, job finding, and income change. We also tested for the buffering effects of these coping strategies on the association between objectively unfavorable labor market conditions (as indicated by regional unemployment rates) and these outcomes. We used four-wave survey data from a longitudinal sample of 620 German adults aged 16–43 years at the first wave and analyzed changes in the three career-related outcomes across 1294 pairs of successive annual waves. Analyses revealed that goal engagement predicted a higher chance of job finding over one year. Moreover, goal engagement buffered the association between higher regional unemployment rates and a higher likelihood of job loss, as well as a lower income, over one year. Goal disengagement predicted a lower income but had no other statistically significant effects. Thus, even in a relatively highly regulated labor market like the German one, goal engagement in coping with occupational uncertainty can contribute to objective career success.     

Getting going and letting go: Religiosity fosters opportunity‐congruent coping with work‐related uncertainties

This study investigated how religiosity relates to goal engagement (i.e., investing time and effort; overcoming obstacles) and goal disengagement (i.e., protecting self‐esteem and motivational resources against failure experiences; distancing from unattainable goals) in coping with perceived work‐related uncertainties (e.g., growing risk of job loss) that arise from current social change. We hypothesised that religiosity not only expands individuals' capacities for both engagement and disengagement but also fosters an opportunity‐congruent pattern of engagement and disengagement, promoting engagement especially under favourable opportunities for goal‐striving in the social ecology and facilitating disengagement especially under unfavourable opportunities. Multilevel analyses in a sample of N = 2089 Polish adults aged 20–46 years partly supported these predictions. Religiosity was associated with higher goal engagement, especially under favourable economic opportunities for goal‐striving in the social ecology (as measured by the regional net migration rate). For disengagement, the results were more mixed; religiosity was related to higher self‐protection independently of the economic opportunity structure and predicted higher goal‐distancing only under the most unfavourable opportunities. These results suggest that religiosity can promote different coping strategies under different conditions, fostering a pattern of opportunity‐congruent engagement and, to some extent, disengagement that is likely to be adaptive.
