The shared attention theory suggests that people devote greater cognitive resources to those features co-attended simultaneously with others, determining better performance in several types of tasks. When co-actors performed a go/no-go Navon task attending different features of target letters, the performance was impaired, reflecting a joint Navon effect (the representation of a co-actor’s attentional focus made it more difficult to select and apply one’s own focus of attention), probably due to asynchronous co-attention with a decrease in cognitive resources involved. Researches in chronobiology and chronopsychology demonstrated that not only selective attention (involved in a Navon task), but also cognitive resources have a daily fluctuations, mainly paralleling the circadian rhythm of body temperature (i.e. increasing values from the morning to evening with a subsequent decline in the night). The study was conducted to assess whether the presence of joint attention, as measured by the joint Navon effect, was influenced by the time-of-day. Sixteen pairs of participants sitting next to each other were required to respond to the identity letters in a go/no-go Navon task twice: in the morning (09:00–10:00) and early afternoon (13:00–14:00). The results showed a joint Navon effect in the morning session only, suggesting that joint attention was affected by the time-of-day effect on cognitive resources. 相似文献

Frailty is a dynamic clinical syndrome considered as part of an age-associated continuum of severity, including pre-frailty as an intermediate frailty status with potential reversibility to robustness. The main purpose of this study was to analyse the relationship between the different domains of quality of life, functional dependence and depressive symptomatology in older adults diagnosed as pre-frail, before progression to frailty occurs. Logistic regression analyses were conducted to examine whether sex, age, level of education and scores in the Geriatric Depression Scale 15-item Short Form (GDS-SF) and the Instrumental Activities of Daily Living Lawton scale determine the worst score in the WHOQOL-BREF (World Health Organization Quality of Life) in older adults meeting one or two frailty phenotypic criteria. Depressive symptomatology (GDS-SF score) was the main determinant of poor quality of life in both groups, and in all areas of WHOQOL-BREF. Age was only associated with poor satisfaction with own health. Female sex and low educational level were linked to low physical QOL and poor self-rated health, respectively, but only in older adults meeting one frailty criterion. Association between functional status and WHOQOL-BREF scores was only found in the univariate analysis. These results underline the importance of identifying multiple aspects, but mainly the presence of depressive symptomatology, as risk factors for all dimensions of quality of life in the pre-frailty process, where interventions might be targeted to reduce the progression of pre-frailty and frailty in older adults. 相似文献

Now you see it, now you don't: explicit versus implicit measures of the personal/group discrimination discrepancy 总被引:1,自引:0,他引:1
When making explicit self-report ratings, members of status- and racial-minority groups report less personal experience with discrimination than that encountered by their group—a phenomenon called the personal/group discrimination discrepancy (PGDD). This study provides evidence, for the first time, that the PGDD may be, in part, a product of the procedure used to measure it. White women and men completed explicit and implicit measures of personal and group discrimination based on sex. The PGDD surfaced among women in the explicit measures, but not in the implicit measures. These findings suggest that explicit and implicit measures might provide different assessments of experience with discrimination. 相似文献

Improving performance in strength tasks requires modifications charateristic of motor skill learning, such as more efficacious motor-unit firing behavior. Because domain-specific knowledge is integral to learning and performing motor kills, the present purpose was to examine selected factors of strength-specific knowledge and effects they might have on acquiring strength. Following baseline testing for maximal strength on a knee-extension task, participants were matched by sex and strength and placed into control (n=8) and treatment (n=8) groups. Quadriceps muscle electromyographic data were also collected. The treatment group underwent two educational sessions detailing muscle physiology, neural control of muscle force, and imagery training using this knowledge. The control group underwent two educational sessions about health and fitness. Following the educational sessions the participants were retested for strength. Analysis indicated that the education and imagery treatment had no effect on strength, nor did electromyographic measures indicate that the treatment group benefitted from intervention. It was concluded that the knowledge was simply not relevant to knee extension-force production or that use of the knowledge involved a disadvantageous internal focus of attention away from relevant task demands. 相似文献

Sankara's philosophy fails definitively at the point where he leaves the human experience—’sinning and suffering‘—unaccounted for. What in each of us, he asks, sins and suffers? Is it the antahkarana, the ‘mental organ’ giving rise to the series of mental states (buddins) that file by illumined by the atman? Impossible, he says, for the antahkarana by itself is material (jada,) and therefore unconscious (acit). Then is it the ātman, upon which the antahkarana is superimposed? Inconceivable, he says, for the atman is identical with Brahman, and Brahman is by definition pure bliss‐consciousness, as far removed from sin and suffering as can be imagined. Then is the atman in conjunction with the antahkarana—a partnership that Sankara calls the jiva (or soul)—the sinner and sufferer? Yes, he says, as long as you remember that the sin and suffering are ultimately illusory, as illusory as the antahkarana itself. I show why Sankara's answer fails and what the failure implies, then suggest a fruitful way to approach Sankara and teach his philsophy to our students. 相似文献

This study compared 66 high-school women, 66 first-year college women, and 66 adult women on four measures of career indecision, the Satisfaction with Career Scale, the Occupational Alternatives Question, the Vocational Decision Making Difficulty Scale, and the Career Decision Scale. The results consistently suggested that the adult women were experiencing more career indecision than the high-school and college women. Intercorrelations among the scales were generally moderate to somewhat low and raised some questions about the use of the Career Decision Scale with adult women. Additional data were gathered on the adult women in an attempt to delineate the sample. Variables included were: marital status, present work experience, the career-related goals and the reasons for pursuing these goals, and possible impediments to reaching the goals. These results are presented and the implications for future research and counseling with adult women are examined. 相似文献

Feeding related lateralization was examined in a population of 23 small-eared bushbabies (Otolemur garnettii). The three measures used to determine lateralization were food reaching, holding, and manipulation. Sex and age differences were found, with adult females showing a strong right bias and adult males a left bias. Juvenile males were weakly lateralized and less consistent across measures than adult animals. The use of standard scores to assess lateralization allowed species comparisons to be made. The results of this study were compared with results from a previous study on lateralization in the ring-tailed lemur (Lemur catta). Species comparisons found sex differences to be a stronger factor in lateralization than species differences. 相似文献
