Assessment and Prediction of Stress-Related Growth 总被引:24,自引:0,他引:24
This article reports the development of the Stress-Related Growth Scale (SRGS) and its use in a study examining determinants of stress-related positive outcomes for college students. Study 1 analyses showed that the SRGS has acceptable internal and test-retest reliability and that scores are not influenced by social desirability. Study 2 analyses showed that college students' SRGS responses were significantly related to those provided by friends and relatives on their behalf. Study 3 analyses tested the determinants of stress-related growth longitudinally. Significant predictors of the SRGS were (a) intrinsic religiousness; (b) social support satisfaction; (c) stressfulness of the negative event; (d) positive reinterpretation and acceptance coping; and (e) number of recent positive life events. The SRGS was also positively related to residual change in optimism, positive affectivity, number of socially supportive others, and social support satisfaction, lending further support to the validity of this new scale. Results have implications for current theory on stress-related positive outcomes. 相似文献

This article reviews criticism of research on judgmental biases in cognitive psychology and suggests caution in applying the findings of this research to research in school psychology. Additionally, it provides suggestions regarding the potential of theory in cognitive psychology to reconcile discrepant findings in selected research on special education decision making. 相似文献

This research examined interpretations of messages as a function of whether they are equivocal or unequivocal, whether they protect self‐face or other‐face, and whether the perceivers of the messages are directly involved in the conversation or overhear it. The role of self‐monitoring and gender were also assessed. Results of Study 1 (N=463) revealed that equivocation is perceived as more polite but less honest and less competent than unequivocal criticism. Equivocation addressing other‐face is the most polite, and criticism of the other is the least polite. Females perceive equivocation as more polite than do males. Ego‐involvement influences perceptions independently and through its interaction with equivocation. No support was found for the role of self‐monitoring or the notion that equivocation conveys a more positive meaning than unequivocal criticism. Study 2 (N = 496) replicated the findings concerning the politeness, honesty, self‐other differences, gender differences, self‐monitoring, and meaning associated with equivocation. 相似文献

Opioid abuse is now considered an epidemic, and many of the adults using this substance are parents. The purpose of the current paper is twofold: (1) to review rigorously conducted studies (e.g., included a comparison group; utilized inferential statistics) examining the association of opioid abuse with parenting and child outcomes, and (2) to review parenting intervention programs with these caregivers. Findings indicate that there are very few rigorously conducted studies examining children and parenting when parents abuse opioids. Furthermore, only four intervention programs have been conducted using randomized control trials and inferential statistics. We conclude that there is limited research that can be labeled as a rigorous science currently addressing this aspect of the opioid epidemic. Recommendations for further research are delineated. 相似文献

Why are some visual stimuli remembered, whereas others are forgotten? A limitation of recognition paradigms is that they measure aggregate behavioral performance and/or neural responses to all stimuli presented in a visual working memory (VWM) array. To address this limitation, we paired an electroencephalography (EEG) frequency-tagging technique with two full-report VWM paradigms. This permitted the tracking of individual stimuli as well as the aggregate response. We recorded high-density EEG (256 channel) while participants viewed four shape stimuli, each flickering at a different frequency. At retrieval, participants either recalled the location of all stimuli in any order (simultaneous full report) or were cued to report the item in a particular location over multiple screen displays (sequential full report). The individual frequency tag amplitudes evoked for correctly recalled items were significantly larger than the amplitudes of subsequently forgotten stimuli, regardless of retrieval task. An induced-power analysis examined the aggregate neural correlates of VWM encoding as a function of items correctly recalled. We found increased induced power across a large number of electrodes in the theta, alpha, and beta frequency bands when more items were successfully recalled. This effect was more robust for sequential full report, suggesting that retrieval demands can influence encoding processes. These data are consistent with a model in which encoding-related resources are directed to a subset of items, rather than a model in which resources are allocated evenly across the array. These data extend previous work using recognition paradigms and stress the importance of encoding in determining later VWM retrieval success. 相似文献

Nanotechnology-enabled cosmetic products (NCPs) have been accessible in the market for the last 30 years. More than 250 products have been commercialized in the global market potentially exposing two billion people. These products are present in all formulations including creams, powders, lotions, and sprays. These involve contact with all body especially skin and mucosae; other tissues like airways and gastrointestinal tract can be reached by accidental exposure. Due to the size, NCPs exhibit an increased surface area volume ratio and biodistribution that potentially augments their reactivity compared with bulk materials, which raises concerns for consumer’s safety. Consumers are attracted by the novel properties and functions of nano-enabled products but expose to technologies where no legal frameworks have been implemented to prevent potential side effects. Here, we review the current gaps between the commercialization process of NCPs and the regulatory frameworks to assess these products in USA, Europe, Japan, and Latin America prior and after commercialization. We identify the requirements for a proper assessment of the potential hazard of nanomaterials (NMs) in cosmetics considering the nanomaterial properties. 相似文献

Field studies and laboratory experiments have documented that a key component of resilience is emotional flexibility--the ability to respond flexibly to changing emotional circumstances. In the present study we tested the hypotheses that resilient people exhibit emotional flexibility: (a) in response to frequently changing emotional stimuli and (b) across multiple modalities of emotional responding. As participants viewed a series of emotional pictures, we assessed their self-reported affect, facial muscle activity, and startle reflexes. Higher trait resilience predicted more divergent affective and facial responses (corrugator and zygomatic) to positive versus negative pictures. Thus, compared with their low-resilient counterparts, resilient people appear to be able to more flexibly match their emotional responses to the frequently changing emotional stimuli. Moreover, whereas high-trait-resilient participants exhibited divergent startle responses to positive versus negative pictures regardless of the valence of the preceding trial, low-trait-resilient participants did not exhibit divergent startle responses when the preceding picture was negative. High-trait-resilient individuals, therefore, appear to be better able than are their low-resilient counterparts to either switch or maintain their emotional responses depending on whether the emotional context changes. The present findings broaden our understanding of the mechanisms underlying resilience by demonstrating that resilient people are able to flexibly change their affective and physiological responses to match the demands of frequently changing environmental circumstances. 相似文献

Abstract Dissociations between different aspects of learning and memory in patients with amnesic syndromes and various neurodegenerative diseases has led to a fundamental revision of the taxonomy of human memory, and a greater understanding of its neurobiological basis. It has been suggested that, while lesions to temporal and diencephalic structures leave procedural learning intact, neurological disorders involving the striatum lead to deficits in this aspect of learning. However, as comparative evidence has accumulated on a variety of procedural tasks, it has become clear that different neurological diseases lead to varying patterns of impaired and intact performance. This has led to a revision of the concept of a unified procedural system in favour of parallel, independent systems, only some of which involve the striatum. There is a danger, however, that the effort to fit the patterns of functional association and dissociation into a neuroanatomical framework may be premature, It is suggested that the way forward lies in more comparative studies, but ones which (1) adopt a broader perspective, assessing other patient groups or single cases, (2) tackle the question of inter-subject variability, (3) adopt a more analytic approach to the assessment of individual performance, and which utilise theory-driven methods to assess the processes of learning at different stages, and (4) which employ complementary methods such as pharmacological manipulations in normal subjects to assess the neurochemical basis of procedural knowledge. 相似文献

Hippocampal c-fos is necessary for long-term memory of a socially transmitted food preference 总被引:1,自引:0,他引:1
The present article examined the requirement of hippocampal c-Fos for learning a socially transmitted food preference (STFP). We reported previously that expression of the c-Fos protein is increased in the dorsal and ventral hippocampus of rats trained on the STFP (Countryman, Orlowski, Brightwell, Oskowitz, & Colombo, 2005). Pretraining intrahippocampal antisense to the immediate early gene c-fos was administered to adult male Long-Evans rats to determine if c-fos expression is necessary for either short- or long-term memory for STFP. Guide cannulae were implanted bilaterally into the dorsal hippocampus. Antisense oligodeoxynucleotides (ODNs) were administered unilaterally either 6.5, 8.5, 10.5, or 12.5 h prior to STFP training while either sense ODNs or saline were infused into the opposite hemisphere. Immunocytochemistry was performed, and cells showing c-Fos immunoreactivity (ir) were counted from the antisense-treated hemisphere and compared to cell counts from the control hemisphere. The results indicated significant suppression of learning-induced c-Fos protein at the 8.5 and 10.5 infusion-train intervals. Additional rats were implanted with cannulae into the dorsal and ventral hippocampus, and antisense ODNs, sense ODNs, or saline were administered bilaterally 8.5h prior to training. Rats were tested immediately and 14 days after training. Rats in all groups showed a significant preference for the demonstrated food at the short-term memory test. At the long-term memory test, however, rats infused with c-fos antisense showed no preference for the demonstrated food whereas rats infused with either sense or saline maintained their preference. The present findings suggest that c-fos is necessary for consolidation of non-spatial hippocampal-dependent memory. 相似文献
