Fibromyalgia is a stress-related disorder characterized by chronic pain, memory impairment, and neuroendocrine aberrations. With the hypothesis that biological and psychological symptoms may underlie the cognitive problems, the relative influences of neuroendocrine function and psychological factors on declarative memory were examined among 50 women with fibromyalgia. This within-group analysis controlled for age, education, pain, and relevant medications. Neuroendocrine function and depression had significant independent associations with memory function. Higher log-transformed mean salivary cortisol levels were associated with better performance on both immediate and delayed visual recall and with delayed verbal recall. Depressive symptoms were negatively associated with verbal recall. These findings suggest that a basic disorder of endocrine stress responses may contribute to the cognitive symptoms experienced by fibromyalgia patients. 相似文献

This meta-analysis examined the validity of various theoretical assumptions about cognitive and behavioral change following a communication recommending condom use. The synthesis comprised 82 treatment and 29 control groups included in 46 longitudinal reports with measures of perceived severity and susceptibility, attitudes and expectancies, norms, perceptions of control, intentions, knowledge, behavioral skills, or condom use. Results indicated that across the sample of studies, communications taught recipients about facts related to HIV and also induced favorable attitudes and expectancies, greater control perceptions, and stronger intentions to use condoms in the future. Moreover, messages that presented attitudinal information and modeled behavioral skills led to increased condom use. Results are discussed in the context of theories of human behavior and change and in reference to HIV-prevention interventions. 相似文献

Although success in managing evolving peer relationships is linked to critical adolescent outcomes, little is known about the specific factors that lead to success or failure in peer relationship development across adolescence. This longitudinal study examines the role of adolescents' level of ego development as a predictor of the future course of several facets of friendship development in early adolescence. Ego development was assessed in a community sample of adolescents at age 13. Several facets of adolescent friendship were also assessed at 13 and then reassessed 1 year later, including adolescent intimate behavior during a supportive interaction with their best friends, adolescent reports of psychological security in their friendships, and peer-rated popularity. As predicted, ego development not only explained concurrent levels of peer functioning but also predicted markers of change over time in each of the assessed domains of peer functioning. Implications for ego development in increasing our understanding of individual differences in adolescent friendship development are discussed. 相似文献

Choice between two reinforcers differing in magnitude and delay was investigated in rats maintained at 80% ( n = 10) or 90% ( n = 10) of their free-feeding body weights using discrete-trials adjusting-delay schedules in which the two reinforcers (S\[mall] and L\[arge]) were associated with different levers. In each phase of the experiment the delay to the smaller reinforcer ( dS ) was held constant, and the delay to the larger reinforcer ( dL ) was varied in accordance with the distribution of choices in successive blocks of trials. The value of dS was varied across the four phases of the experiment (2, 4, 8, and 2 sec). When dS was 2 sec, the mean value of dL was higher in the rats maintained at 80% than in those maintained at 90% of their free-feeding body weights. When dS was increased, the value of dL increased in both groups; however the effect of deprivation level was abolished. The results are consistent with a model of choice that posits hyperbolic relations between reinforcer value and reinforcer magnitude, and between reinforcer value and delay of reinforcement. 相似文献
