Mourners often rely on faith following loss, but not all find spirituality comforting. Some grievers engage in negative religious coping (NRC), signaled by behaviors and thoughts such as anger toward God or their faith community, feeling spiritually abandoned, or questioning God's power. Our longitudinal study of 46 African American homicide survivors explored the relation of both positive religious coping (PRC) and NRC to complicated grief (CG) and investigated whether religious coping more strongly predicted psychological distress or vice versa. Results indicated that NRC was associated with CG, whereas PRC was substantially unrelated to bereavement outcome. Significantly, CG prospectively predicted high levels of spiritual struggle 6 months later, both in terms of CG and NRC composite scores and at the individual-item level. Clinical implications regarding spiritually sensitive interventions are noted. 相似文献

From an initial sample of fifteen Christian character development curricula, ten were selected for more in-depth analysis. Three were eventually chosen as exemplary models of curricula that promote Sermon on the Mount qualities, considered as the ultimate expression of holy nation citizenship expectations. 相似文献

The authors explored adolescent physical fighting and weapon carrying, using in‐home interviews with 1,098 middle/high school students and their parents. Logistic regression analyses examined the relationship between youth assets and the risk behaviors while controlling for demographic information. Both demographic factors and assets were associated with no physical fighting, and 6 of 9 assets were linked to not carrying a weapon. These findings indicate that certain assets may protect youth from physical fighting and carrying a weapon. 相似文献

The authors examined the relationship between sibling structure variables (i.e., gender, number of sisters, number of brothers, sibling spacing, number of siblings, and birth order, all men, and all women siblings) and current relationships with parents and spouse/partners. Participants included 519 adults between the ages of 19 and 59 years. Two separate canonical correlations were conducted. The results for men indicated that being a younger man with an all‐male sibling group was related to more intimacy with parents and more intimidation by parents. For women, being an older woman with more brothers and more siblings was related to less intimidation by parents and less intimacy with parents and spouses/partners. 相似文献

Rural to urban migration has become a prominent phenomenon in China. In linking migration to children’s school trajectories, this mixed-methods study explored a range of cultural and contextual factors that contribute to Chinese children’s school wellbeing in the migratory process. The key variables included acculturative attitudes, economic stress, and relationships with family, teachers and peers. The study drew upon survey data from a sample of 301 Chinese migrant students (4th–9th grade) together with in-depth interviews involving ten selected students focusing on how migrant children’s school happiness and productivity are influenced by acculturation, economic hardship, and social relationships. The quantitative analysis indicated the critical role of integrative states in promoting school satisfaction and achievement. Migrant children with better social relations scored higher levels of hope, which in turn contributed to better school outcomes. Contrary to previous findings, economic stress did not hinder school outcomes for these Chinese migrant children, but appeared to act as a positive motivational factor for pursing academic success. The qualitative analysis echoed the quantitative findings, and provided further explanations for the complexity and particularity of these phenomena. 相似文献

Sleep-activity patterns were objectively recorded over a 24-hr period in 19 elderly nursing home residents. On average, both sleep and wake times were observed during every hour of the 24 recorded hours; however, the sleep pattern of the residents was fragmented so that they rarely experienced even a single hour of consolidated time spent sleeping. It is hypothesized that several independent factors, including compensation for lost sleep, increased total time in bed, weakening of social constraints, and deterioration of the circadian sleep-wake rhythm, are interacting to produce this increase in sleep fragmentation. 相似文献

ACTH 4-9 analog can retard spatial alternation learning in brain damaged and normal rats 总被引:1,自引:0,他引:1
Thirty adult male hooded rats (Long-Evans strain) were assigned randomly to one of three lesion groups (n = 10) and prepared with medial frontal, posterior parietal, or sham neocortical injuries. Following a recovery interval of 10-12 days, access to water was limited to 30 min per day and the rats were shaped to traverse a T-maze for a reward of sweetened water. After a pretraining criterion was attained, osmotic minipumps (Alzet 2002) were installed subcutaneously. The minipumps delivered chronically for the next 14 to 15 days either 0 or 1.2 micrograms of ACTH 4-9 dissolved in bacteriostatic saline per day while the rats were trained on a reinforced spatial alternation task. Analysis of the number of errors made to a criterion of at least 80% correct alternations in two consecutive training sessions, or a ceiling of 62 errors (attained by two rats with parietal lesions), revealed that learning was impaired in the rats with parietal injuries. Contrary to our hypothesis, animals receiving ACTH 4-9 committed more errors than their counterparts receiving only saline. 相似文献

This study compared the temporal organization of graphic movements executed either actually or mentally. Six subjects had to perform two tasks, writing a sentence and drawing a cube, either as a real performance or as an imagined one, with either the right or the left hand, and with either a small or a large tracing amplitude. In the same subject, for the same hand, mental and actual movement times were both very stable and very close from trial to trial regardless of the tracing amplitude. Thus, mental movements mimic closely real movements in their temporal organization and are likely to involve the same planning program. 相似文献

This study evaluated the neuropsychological performance of adults with and without Attention Deficit Hyperactivity Disorder
(ADHD) during the Paced Auditory Serial Addition Test (PASAT), Wisconsin Card Sorting Test: Computerized Version 3 (WCST),
and the Integrated Visual and Auditory Continuous Performance Test (IVA). Quantitative electroencephalographic (QEEG) data
were also collected during task performance to examine differences in cortical activity between groups and tasks. Results
suggest that adults with ADHD demonstrated lower levels of performance on the PASAT and IVA, tasks that involve working memory
and processing speed, and sustained attention, respectively. Adults with ADHD also had more upper alpha activity during the
IVA. Lastly, for the ADHD group, an increased theta/beta ratio during the IVA was significantly related to poorer attentional
performance. The current results support reinforcing specific types of cortical activity though EEG operant conditioning (neurofeedback)
as a treatment option in adults with ADHD.
This paper is based largely in part on a dissertation by J. Noland White in partial fulfillment of the requirements of his
doctoral program at The University of Tennessee. Portions of this study have been presented in summary form at several professional
conferences. 相似文献

Gaze direction is a vital communicative channel through which people transmit information to each other. By signaling the locus of social attention, gaze cues convey information about the relative importance of objects, including other people, in the environment. For the most part, this information is communicated via patterns of gaze direction, with gaze shifts signaling changes in the objects of attention. Noting the relevance of gaze cues in social cognition, we speculated that gaze shifts may modulate people's evaluations of others. We investigated this possibility by asking participants to judge the likability (Experiment 1) and physical attractiveness (Experiment 2) of targets displaying gaze shifts indicative of attentional engagement or disengagement with the participants. As expected, person evaluation was moderated by the direction of gaze shifts, but only when the judgment under consideration was relevant to participants. We consider how and when gaze shifts may modulate person perception and its associated behavioral products. 相似文献
