Eating knowledge, nutritional knowledge, and psychological changes among female collegiate dancers were examined before and after a 4-wk. team-centered program on sport nutrition, exercise, and disordered eating consequences. Collegiate female dancers from two NCAA Division I institutions participated in a control (n = 19; M age = 19.1 yr., SD = 1.0) or intervention (n = 21; M age = 19.2 yr., SD = 1.2) group. Measures were administered to both groups before and after intervention to assess eating disorders, depression, and nutritional and disordered eating knowledge. There was a statistically significant increase in scores on nutritional and overall eating disorder knowledge in the intervention group compared to the control group. Mean scores on depression, drive for thinness, body dissatisfaction, and maturity fears decreased in the intervention group. 相似文献

The psychosocial literature contains empirical evidence of the effects of personality variables on commitment to acts. The association of economic opportunism was explored with respect to postexperimental attitude change, intentions, and intrinsic motivation of individuals (N=132) toward acts with either forced compliance or compliance without pressure. In conditions of commitment and compliance without pressure, both intention and intrinsic motivation decreased as economic opportunism increased, while in conditions of commitment and forced compliance, intention increased as economic opportunism increased. Attitude change and economic opportunism did not appear to be associated in any experimental condition. These findings suggest that tendency to noncooperativeness predisposes to reduced concern for consistency and compliance with performed acts. 相似文献

This study applied the theory of planned behaviour (TPB) to the prediction of breast self-examination (BSE) intentions and behaviour, and tested whether the frequency of past behaviour and context stability moderates intention-behaviour and habit-behaviour relations. Seventy-seven females completed measures of the TPB, frequency of past behaviour, context stability and habit strength (Self-Report Habit Index). BSE behaviour was assessed at 1-month follow-up (n?=?66). The TPB explained 33% of the variance in BSE intentions and 11% of the variance in time 2 BSE. The frequency of past behaviour moderated the intention-behaviour relationship such that the intention was only positively related to time 2 BSE behaviour when the frequency of past behaviour was low. Context stability and the combination of the frequency of past behaviour?×?context stability moderated the habit-behaviour relationship such that habit strength was only positively related to time 2 BSE behaviour when context stability and the combination of frequency of past behaviour?×?context stability were high. The results are consistent with the proposal that behaviours that are performed frequently in stable contexts are predominantly under the control of habitual processes, whereas behaviours that are performed infrequently in unstable contexts are predominantly under the control of intentional processes. 相似文献

In this study, we used process measures to understand how people recall autobiographical memories in response to different word cues. In Experiment 1, participants provided verbal protocols when cued by object and emotion words. Participants also reported whether memories had come directly to mind. The self-reports and independent ratings of the verbal protocols indicated that directly recalled memories are much faster and more frequent than generated memories and are more prevalent when cued by objects than emotions. Experiment 2 replicated these results without protocols to eliminate any demand characteristics or output interference associated with the protocol method. In Experiment 3, we obtained converging results using a different method for assessing retrieval strategies by asking participants to assess the amount of information required to retrieve memories. The greater proportion of fast direct retrievals when memories are cued by objects accounts for reaction time differences between object and emotion cues, and not the commonly accepted explanation based on ease of retrieval. We argue for a dual-strategies approach that disputes generation as the canonical form of autobiographical memory retrieval and discuss the implication of these findings for the representation of personal events in autobiographical memory.

While a general stereotype exists that men are better at navigating than women, experimental evidence indicates that men and women differ in their use of spatial strategies, and this preference determines gender-differences. When both environmental geometry and landmark cues are available, men appear to learn to navigate using both types of cues, while women show a preference for using landmarks. Using a computer-generated task, 80 undergraduate students from North-East England learned to navigate to a hidden goal. Activating the general navigation stereotype improved the performance of men, compared to the control condition, both when only geometric cues and only landmark cues were present (stereotype lift), suggesting that activating a general stereotype can affect tasks both with (geometry) and without (landmark) established gender-differences in preference. In addition, in the test trial (hidden goal removed) women who learned to navigate using only landmarks spent longer in the correct location of the hidden goal than those who learned to navigate using only geometry. In contrast, the opposite result was found for men, suggesting that when only one cue-type is available, gender-differences still occur, with women better able to navigate using landmarks than geometry, while men seemed to learn more about the location of the goal with reference to geometric than landmark cues. 相似文献

Little is known about potential participants' views about research, their willingness to participate in research, and the extent to which they might be susceptible to coercive attempts to compel their participation, particularly among populations at risk for exploitation (e.g., offenders). The extent to which individual differences variables, such as personality constructs (e.g., psychopathic traits), might affect participants' attitudes toward research is also essentially unknown. The present study sought to examine the psychopathy constructs of Fearless Dominance (FD) and Self-Centered Impulsivity (SCI) via the Multidimensional Personality Questionnaire-Brief Form (MPQ-BF) to assess the extent to which these traits predict attitudes towards research and susceptibility to coercion within a diverse criminal justice sample (N?=?631). SCI was modestly associated with perceptions that illicit pressures regarding research participation were likely to occur, and participants high in these traits appeared somewhat vulnerable to succumbing to coercive influences. In contrast, FD failed to predict the likelihood that illicit pressures regarding research participation would occur as well as the potential that these pressures would have to impact participants' voluntariness and likelihood of participating. Implications for recruiting potential participants for research in correctional settings are discussed. 相似文献

We evaluated a clinical "go/no-go" reaction time test (recognition RTclin) that is portable and does not require a computer, and used it to quantify the effect of age on recognition RTclin test scores. Fifty-two healthy adults 19-83 years old completed simple and recognition RTclin testing. Simple RTclin was measured as the elapsed time from initial release of a suspended vertical shaft by the examiner until its arrest by participant pinch grip. Recognition RTclin was similar except that a light on the apparatus randomly illuminated in 50% of the trials to signal the participant to arrest the device. To help interpret the RTclin results, we partitioned them into premovement time (PMT) and movement time (MT) using an optoelectronic camera system that is not ordinarily part of the RTclin test. Recognition RTclin scores were significantly slower than simple RTclin scores, with 71% of the prolongation attributable to PMT. While simple RTclin test scores correlated with age, recognition RTclin scores did not. A strong negative association between recognition RTclin accuracy and age was found. Recognition RTclin is feasible to measure in healthy adults and appears to represent a portable, computer-independent measure of cognitive processing speed and inhibitory capacity. Potential applications include assessment of brain injury, dementing illness, medication side effects, fall risk, and safe driving. 相似文献

In response to the article by Scofield, I consider the that, how, and why of ethics consultation, moral expertise, and the rules of the game. The question still to be engaged is, how does all of this work out for patients and families? 相似文献

We examined neuronal correlates of forgetting in rats by detection of phosphorylated mitogen-activated protein kinase (pMAPK) in the medial prefrontal cortex (mPFC) and amygdala. In Experiment 1, postnatal day (P)23 and P16 rats received paired noise CS-shock US presentations. When tested immediately after conditioning, P23 and P16 rats exhibited similar levels of conditioned fear; when tested after 2 days, however, P16 rats showed poor CS-elicited freezing relative to P23 rats. In Experiment 2, P16 and P23 rats received either paired or unpaired CS-US presentations, and then were tested 48 h later. Consistent with Experiment 1, P16 rats showed forgetting whereas P23 rats exhibited good retention at test. Additionally, unpaired groups showed poor CS-elicited freezing at test. Immunohistochemistry showed that P23 and P16 rats given paired presentations exhibited significant elevation of pMAPK-immunoreactive (ir) neurons in the amygdala compared to rats given unpaired presentations. That is, MAPK phosphorylation in the amygdala tracked learning history rather than behavioral performance at test. In contrast, only the P23-paired group showed an elevated number of pMAPK-ir neurons in mPFC, indicating that MAPK phosphorylation in the mPFC tracks memory expression. Different test-perfusion intervals were employed in Experiment 3, which showed that the developmental dissociation in the pMAPK-ir neurons observed in the mPFC in Experiment 2 was not due to age differences in the rate of phosphorylation of MAPK. These findings provide initial evidence suggesting that while the mPFC is involved in memory retrieval, MAPK phosphorylation in the amygdala may be a persisting neural signature of fear memory. 相似文献
