AbstractA crucial component of locomotion and mobility is the successful navigation of apertures (e.g., doorways, lanes, corridors). While much research has studied perceptions of action capabilities in a static environment, far less work has considered how action capabilities change in a dynamic environment, particularly when the environment moves in unpredictable ways. The current experiment assessed actors’ perceptions of aperture passability for a dynamically moving gap. In an immersive virtual environment, participants were seated in a wheelchair rolling toward a sliding door while the door oscillated to various widths. The patterns of oscillation were manipulated in terms of their amplitude (sequence standard deviation), predictability (sequence sample entropy), and base width (sequence mean) in a within-participants design. Participants gave judgments of passability within a temporal occlusion paradigm. Results showed that both the amplitude and predictability of the oscillating door impacted the reliability of passability judgments. We suggest that these variables act to alter the salience of optical constraints (e.g., attractors and repellors) within a dynamical systems framework. 相似文献

The effectiveness of support group interventions for cancer patients has been established among White patients but has been virtually unstudied among minority patients. The current study represents the 1st randomized support group intervention targeted to African American women with breast cancer. Participants (N = 73) with nonmetastatic breast cancer were randomly assigned to an 8-week group intervention or an assessment-only control condition At 12 months, the intervention resulted in improved mood as well as improved general and cancer-specific psychological functioning among women with greater baseline distress or lower income. Subsequent research is needed to address effective methods of enrolling and following women with fewer psychosocial and financial resources, as they were the most likely to benefit from this particular intervention. 相似文献
