Do older individuals have difficulty processing motion or excluding noise? Implications for safe driving

This study aimed to determine if difficulties extracting signal from noise explained poorer coherent motion thresholds in older individuals, particularly women. In four experimental conditions the contrast of the signal and noise dots used in a random dot kinematogram was manipulated. Coherence thresholds were highest when the signal dots were of a lower contrast than the noise dots and lowest when the signal dots were of a higher contrast than the noise dots. In all conditions the older group had higher coherence thresholds than the younger group, and women had higher thresholds than men. Significant correlations were found between coherence thresholds and self-reported driving difficulties in conditions in which the signal dots had to be extracted from noise only. The results indicate that older individuals have difficulties extracting signal from noise in cluttered visual environments. The implications for safe driving are discussed.     

Mindfulness-based stress reduction among Emirati Muslim women

Explorations of mindfulness-based psychotherapeutic approaches are relatively scarce outside of Europe and North America. This study examined the effectiveness and the religio-cultural appropriateness/acceptability of a Mindfulness-based Stress Reduction (MBSR) programme among Muslim citizens of the United Arab Emirates. Emirati college women (N?=?12) were enrolled in an eight-week, group-based, MBSR programme. After completing the programme, participants attended a focus group exploring their perceptions of MBSR, with a particular emphasis on exploring the cultural appropriateness of this approach. The MBSR programme was favourably evaluated, and not in any way deemed antithetical towards the participants' own theistic or cultural traditions. The results are discussed with reference to identifying bridging concepts to help better contextualise MBSR for people who spontaneously couch their experiences in religious themes, or who explicitly express a desire for faith-affiliated interventions.     

The Influence of Neighborhood Aesthetics,Safety, and Social Cohesion on Perceived Stress in Disadvantaged Communities

Limited research has explored how specific elements of physical and social environments influence mental health indicators such as perceived stress, or whether such associations are moderated by gender. This study examined the relationship between selected neighborhood characteristics and perceived stress levels within a primarily low‐income, older, African‐American population in a mid‐sized city in the Southeastern U.S. Residents (n = 394; mean age=55.3 years, 70.9% female, 89.3% African American) from eight historically disadvantaged neighborhoods completed surveys measuring perceptions of neighborhood safety, social cohesion, aesthetics, and stress. Multivariate linear regression models examined the association between each of the three neighborhood characteristics and perceived stress. Greater perceived safety, improved neighborhood aesthetics, and social cohesion were significantly associated with lower perceived stress. These associations were not moderated by gender. These findings suggest that improving social attributes of neighborhoods may have positive impacts on stress and related benefits for population health. Future research should examine how neighborhood characteristics influence stress over time.
