Protective factors for fostering reasons for living were examined among low-income, suicidal, African American women. Bivariate logistic regressions revealed that higher levels of optimism, spiritual well-being, and family social support predicted reasons for living. Multivariate logistic regressions indicated that spiritual well-being showed unique predictive value for reasons for living. Further, the multivariate model accurately predicted reasons for living 72% of the time. Partial support was found for a cumulative protective model hypothesizing a linear relationship between the number of protective factors endorsed and increased reasons for living. Implications for community-based preventive and recovery-oriented intervention efforts and future research are discussed.  相似文献

A large body of evidence suggests that action execution and action observation share a common representational domain. To date, little is known about age-related changes in these action representations that are assumed to support various abilities such as the prediction of observed actions. The purpose of the present study was to investigate (a) how age affects the ability to predict the time course of observed actions; and (b) whether and to what extent sensorimotor expertise attenuates age-related declines in prediction performance. In a first experiment, older adults predicted the time course of familiar everyday actions less precisely than younger adults. In a second experiment, younger and older figure skating experts as well as age-matched novices were asked to predict the time course of figure skating elements and simple movement exercises. Both young age and sensorimotor expertise had a positive influence on prediction performance of figure skating elements. The expertise-related benefit did not show a transfer to movement exercises. Together, the results suggest a specific decline of action representations in the aging mind. However, extensive sensorimotor experience seems to enable experts to represent actions from their domain of expertise more precisely even in older age.  相似文献

Depression has been linked to increased cortisol concentrations using point measures taken from urine, blood, or saliva samples. However, with regard to hypercortisolism-induced consequences, long-term cumulative cortisol burden is of relevance. Our objective was to use hair analysis as a new method to assess cortisol exposure over 6 months in depressed patients and healthy controls. We examined 23 depressed patients (8 men and 15 women, mean age: 41.6 years (?±?standard deviation (SD), 13.1 years); mean duration of current depressive episode 9 months (?±?SD, 13 months)) and 64 healthy controls, matched for age and gender. Cortisol concentrations in two 3-cm hair segments from near to the scalp were analyzed, representing cortisol secretion during the 6 months prior to sampling. Compared with healthy individuals, depressed patients had higher hair cortisol concentrations in the first (mean?±?SD: 26.7?±?20.8 vs. 18.7?±?11.5?pg/mg, p?相似文献

This paper began by suggesting that culture might influence how people construe workplace bullying. Referring back to the studies of cultural differences in cognition, it was suggested that people of the Far East might construe workplace bullying differently from the people of Western countries. Taking South Korean culture as an example, this paper explained how historical background and culture shaped Korean's psyche in relation to workplace bullying. Currently available evidence was discussed including the way Koreans construed workplace bullying and how close social bonding might act as a buffer against a conflict escalating into bullying.  相似文献

In 1986, we published inBehavior Research Methods, Instruments, & Computers a small library of assembler code for the public domain that permitted accurate millisecond timing for Apple’s Macintosh computer. That version of MilliTimer used the Versatile Interface Adapter chip’s Timer 1 (VIA T1), which is part of the standard Macintosh hardware configuration. The VIA T1, however, is also used by the Sound Manager, and thus the use of sound and accurate millisecond timing were incompatible. We offer for the public domain a new version labeled MilliTimer 2.2, which permits psychologists and other researchers to use the full capabilities of the Macintosh. MilliTimer 2.2 is compatible with popular teaching, research, and clinical tools such as Hyper-Card and MacLaboratory. MilliTimer 2.2 employs the Macintosh Time Manager, which is a part of the Macintosh operating system and is supported by Apple for the 512KE, Plus, SE, and Macintosh II machines. MilliTimer 2.2 is hardware-independent and automatically self-corrects for other operating system activities that also use the Time Manager. The self-correcting function is limited, however, and can result in a nonaccumulating error averaging about ?3 msec. To preserve compatibility with earlier machines that do not contain the Time Manager, a simple mode parameter allows MilliTimer 2.2 to use the older, more accurate timing method.  相似文献

Do the reformulated model of learned helplessness and the self-control model apply to clinically depressed children? Are the related cognitive patterns specific to depression? Are the cognitive deficits associated with depression learned from one's parents? To address these questions this investigation examined three groups of children (ages 8–12) and their parents: nonclinic (n =25),nondepressed clinic (n=22),and depressed clinic (n=15).Children were diagnosed depressed on the basis of Kiddie-SADS interview data. Depressed clinic children self-reported more depression, had a more depressive attributional style, and had more self-control problems. There were more depressed mothers in the clinic than in the nonclinic sample. Depressed clinic children had more depressed mothers than did nondepressed clinic children. There were no differences among the three groups of parents in their cognitive patterns. No relationship was found between the attributional style and self-control behavior of children and their parents.  相似文献

We report two experiments that investigate the abilities of aphasic subjects with lexical and short-term memory impairments to learn supraspan lists of 10 words. We examined effects of stimulus factors (characteristics of words and lists to be learned) and subject factors (verbal and nonverbal STM span, nature of language impairment). Learning ability was influenced by the imageability and frequency of the words to be learned (Experiment 1) and by the linguistic relationship among words in a list (Experiment 2). Additionally, learning ability was affected by the nature of a subject's word processing deficit (whether it involved semantic and/or phonological processes). Phonological ability was positively associated with learning in both experiments, and semantic ability was associated with learning when words in a list were high in both frequency and imageability (Experiment 1) or were contextually related to one another (Experiment 2). Finally, verbal STM span was positively related to learning performance, but the effect was more pronounced for word span than digit span. These relationships among word processing ability, verbal STM span, and learning ability are discussed with reference to learning in aphasia and to models of learning more generally.  相似文献
