Human service students were surveyed (N = 207) to determine their perceptions about homeless elders and communal responsibility for their well-being. Using a backward regression analysis, a final model (F = 15.617, df = 7, p < .001) for Perceptions about Homeless Persons and Community Responsibility (predicted variable) included the predictor variables of Homeless Older Persons Are Afraid and Lonely; Homeless Persons and Health Issues; History of Homeless Older People's Life on the Street; Touching a Homeless Older Person; Hygiene and Homeless Older People; Interest in Working with Elders; and Educational status. The findings indicated that the predictor variables accounted for more than 36% of the variance in Perceptions about Homeless Older Persons and Community Responsibility (R 2 = .386; adjusted R 2 = .361). 相似文献

Cognition is important in many sports, for example, making split-second-decisions under pressure, or memorising complex movement sequences. The dual-task (DT) paradigm is an ecologically valid approach for the assessment of cognitive function in conjunction with motor demands. This study aimed to determine the impact of impaired intelligence on DT performance. The motor task required balancing on one leg on a beam, and the cognitive task was a multiple-object-tracking (MOT) task assessing dynamic visual-search capacity. The sample included 206 well-trained athletes with and without intellectual impairment (II), matched for sport, age and training volume (140 males, 66 females, M age = 23.2 ± 4.1 years, M training experience = 12.3 ± 5.7 years). In the single-task condition, II-athletes showed reduced balance control (F = 55.9, P < .001, η2 = .23) and reduced MOT (F = 86.3, P < .001, η2 = .32) compared to the control group. A mixed-model ANCOVA revealed significant differences in DT performance for the balance and the MOT task between both groups. The DT costs were significantly larger for the II-athletes (?8.28% versus ?1.34% for MOT and ?33.13% versus ?12.89% for balance). The assessment of MOT in a DT paradigm provided insight in how impaired intelligence constrains the ability of II-athletes to successfully perform at the highest levels in the complex and dynamical sport-environment. 相似文献
