This study tests the relationship between pessimistic explanatory style and illness with questionnaire data. Questionnaires were administered to 234 college students at a mid‐sized Western university. Four variables were tested as potential mediators of the pessimistic explanatory style/illness relationship: symptoms of depression, perceived stress, social support, and poor health practices. Results indicated that only the global dimension of pessimistic explanatory style was related to experiences of illness, and hence was the only dimension that could be mediated by the proposed variables. Results demonstrated that symptoms of depression mediated the relationship between global attributions for negative events and illness. Exploratory analyses also suggest that stress is implicated in this process such that it increases symptoms of depression, which in turn influence illness.  相似文献

The National Society of Genetic Counselors (NSGC) supports the development of practice recommendations (guidelines) in the field of genetic counseling. This paper reviews the basic components of NSGC genetic counseling practice recommendations as well as the process for formal adoption of such documents, as approved by the Board of Directors of the NSGC.  相似文献

Nineteenth-century Jesuit priest and poet, Gerd Manley Hopkins (1844–89), produced poems on natural themes which were not only revolutionary for their structure and style but also disctinctive and forward-looking for their treatment of the environment. In these poems, he presents nature as intrinsically (rather than instrumentally) valuable, God as concerned with the salvation not only of humans but of the environment, and humankind as responsible noy only for polluting the Earth but for participating in its salvation. Christian poets of the twenty-first century need to hees and follow Hopkin's example.  相似文献

Two sets of experiments on flavour aversion conditioning in rats examined the effects of the following factors: the nature of the flavour serving as the conditioned stimulus (CS), which was either a compound of monsodium glutamate, sucrose and quinine, or an elemental flavour, either sucrose or dilute acid; the amount of the CS rats consumed on a single conditioning trial-4 ml or 1 ml; and whether rats had been pre-exposed to the CS before this conditioning trial. There were three main findings. First, conditioning to an elemental CS was unaffected by the amount consumed on the conditioning trial, but conditioning to 1 ml of the compound CS was poorer than to 4 ml. Second, pre-exposure produced a latent inhibition effect if the CS was an elemental flavour, or if rats were allowed to drink 4 ml of the compound solution on their conditioning trial. But, third, pre-exposure facilitated conditioning in rats given only 1 ml of the compound solution as their CS.  相似文献

In two appetitive licking experiments, thirsty rats were pre-exposed to two stimuli prior to conditioning sessions in which one or both of these stimuli were paired with water. Consistent with other results, latent inhibition was disrupted when conditioning took place in a context different from that in which stimulus pre-exposure had occurred. But in animals given prior exposure to the context of stimulus pre-exposure before the start of stimulus pre-exposure, substantial and equivalent latent inhibition was evident whether or not there was a change of context between stimulus pre-exposure and conditioning. These results are discussed in terms of current theories of latent inhibition.  相似文献

This study compared the effects of immediate self-correction, delayed self-correction, and no correction on the acquisition and maintenance of multiplication facts by a fourth-grade student with learning disabilities. Data from daily and maintenance tests indicated that both correct response rate and accuracy were higher when self-correction was immediate rather than delayed or absent.  相似文献
