Using a multifactorial model, sex differences in academic performance were examined in a sample of 347 elementary school children. As expected, girls' academic performance averaged higher than boys'. Path analysis confirmed initial hypotheses that girls' advantage is partially due to their characteristic of greater responsiveness to social cues and compliance with adult direction. This advantage was partially offset in this model by boys' greater visual-spatial skill, which also was a predictor of academic success. Access to stereotypic masculine toys and activities at home was, for both sexes, a predictor of children's visual-spatial ability. As expected, socioeconomic variables, including mothers' occupation and fathers' level of education, also influenced the environmental, social, and cognitive factors predicting academic success. These results indicate that boys' and girls' differential development of specific cognitive and social skills may play an important role in establishing sex differences in academic performance. 相似文献

According to the positive illusions model ( Murray, Holmes, & Griffin, 1996a ), people in romantic relationships are more satisfied when they view their partners more favorably than the partners see themselves. By contrast, shared reality theory ( Hardin & Conley, 2001 ) emphasizes the benefits of perceiving a partner as the partner sees himself or herself. We analyzed archived data from the American Couples Study ( Blumstein & Schwartz, 1983 ) to test the applicability of the positive illusions model to gay and lesbian relationships. Structural equation models demonstrated that the positive illusions model effectively explains relationships among lesbian, gay, heterosexual cohabitating, and married couples. 相似文献

The aim of the current study was to determine whether age and body satisfaction predict dietary adherence in adolescents with
Inflammatory Bowel Disease (IBD), and whether older females are less adherent than younger males and females. Forty-four participants
aged 10–21 with IBD were recruited. Participants provided informed consent and demographics. Body satisfaction was measured
by a questionnaire and a task in which participants selected their current and ideal body image out of silhouettes depicting
bodies ranging from underweight to obese. Adherence was measured by marking a 100 mm visual analog scale, the 1-week completion
of a dietary log, and a questionnaire evaluating coping strategies used for overcoming obstacles to dietary adherence. Age
was related to dietary adherence, with younger children being more likely to adhere. Participants more satisfied with their
body reported better dietary adherence. Findings remained consistent across multiple measures of body satisfaction and adherence.
Healthcare providers and parents should be informed of these findings in order to improve adherence. 相似文献

The direct method of assessing "unrealistic optimism" employs a question of the form, "Compared with the average person, what is the chance that event X will occur to you?" It has been proposed that when individuals construct their responses to this question (direct-estimates) they focus much more strongly on estimates of their own risk (self-estimates) than on estimates of the average person's risk (other-estimates). A challenge to this proposal comes from findings that interventions that alter other-estimates also change direct-estimates. Employing a novel intervention technique, we tested the possibility that such interventions may indirectly also change self-estimates and that this is what accounts for their effect on direct-estimates. Study 1 (n = 58) showed that an intervention which was designed to (and did) affect other-estimates also affected self-estimates, while Study 2 (n = 101) showed that it affected direct-estimates. Study 3 (n = 79) confirmed that we could modify the intervention so as to maintain the effect on other-estimates, but eliminate that on self-estimates. Study 4 (n = 112) demonstrated that when this was done, there was no longer any effect on direct-estimates. The findings are consistent with the proposal that direct-estimates are constructed largely just out of self-estimates. Implications for heath education programs are discussed. 相似文献

Individuals typically believe that they are less likely than the average person to experience negative events, a phenomenon termed "unrealistic optimism". The direct method of assessing unrealistic optimism employs a question of the form, "Compared with the average person, what is the chance that X will occur to you?". However, it has been proposed that responses to such a question (direct-estimates) are based essentially just on estimates that X will occur to the self (self-estimates). If this is so, any factors that affect one of these estimates should also affect the other. This prediction was tested in two experiments. In each, direct- and self-estimates for an unfamiliar health threat - homocysteine-related heart problems - were recorded. It was found that both types of estimate were affected in the same way by varying the stated probability of having unsafe levels of homocysteine (Study 1, N=149) and varying the stated probability that unsafe levels of homocysteine will lead to heart problems (Study 2, N=111). The results are consistent with the proposal that direct-estimates are constructed just from self-estimates. 相似文献

On the basis of lesions of different brain areas, several neural systems appear to be important for processing information regarding different types of learning and memory. This paper examines the development of pharmacological and neurochemical approaches to multiple memory systems from past studies of modulation of memory formation. The findings suggest that peripheral neuroendocrine mechanisms that regulate memory processing may target their actions toward those neural systems most engaged in the processing of learning and memory. In addition, measurements of acetylcholine release in different memory systems reveals extensive interactions between memory systems, some cooperative and some competitive. These results imply that many neural systems, often characterized as relatively independent, may in fact interact extensively, blurring the dependencies of different memory tasks on specific neural systems. 相似文献

Results from studies of retrograde amnesia provide much of the evidence for theories of memory consolidation. Retrograde amnesia gradients are often interpreted as revealing the time needed for the formation of long-term memories. The rapid forgetting observed after many amnestic treatments, including protein synthesis inhibitors, and the parallel decay seen in long-term potentiation experiments are presumed to reveal the duration of short-term memory processing. However, there is clear and consistent evidence that the time courses obtained in these amnesia experiments are highly variable within and across experiments and treatments. The evidence is inconsistent with identification of basic temporal properties of memory consolidation. Alternative views include modulation of memory and emphasize the roles that hormones and neurotransmitters have in regulating memory formation. Of related interest, converging lines of evidence suggest that inhibitors of protein synthesis and of other biochemical processes act on modulators of memory formation rather than on mechanisms of memory formation. Based on these findings, memory consolidation and reconsolidation studies might better be identified as memory modulation and "remodulation" studies. Beyond a missing and perhaps unattainable time constant of memory consolidation, some current views of memory consolidation assume that memories, once formed, are generally unmodifiable. It is this perspective that appears to have led to the recent interest in memory reconsolidation. But the view adopted here is that memories are continually malleable, being updated by new experiences and, at the same time, altering the memories of later experiences. Studies of memory remodulation offer promise of understanding the neurobiological bases by which new memories are altered by prior experiences and by which old memories are altered by new experiences. 相似文献
