Emotional rumination and inhibition were identified in the Emotion Control Questionnaire (ECQ—Roger and Nesshoever 1987; Roger and Najarian 1989) as two relatively independent dimensions of emotional style, and the two measures have subsequently been shown to be important moderator variables in a range of health and forensic settings. Two other dimensions that emerged in the ECQ, labelled aggression control and benign control, have been shown to form part of the extraversion constellation, and the present paper describes the construction and validation of a new scale focusing exclusively on rumination and inhibition. Revised and expanded item pools for the scales were subjected to exploratory and confirmatory factor analyses, which endorsed the two-factor structure. The new scales were validated concurrently against related scales in different samples, and were shown to be systematically related to two independent indices of health status. 相似文献

Sex Differences and Similarities in Video Game Experience,Preferences, and Self-Efficacy: Implications for the Gaming Industry 总被引:1,自引:0,他引:1

As computer technology continues to pervade every facet of life, the study of video game playing becomes more relevant. Studies
show that sex differences continue to exist between men and women, boys and girls, in video game experience, favoring males.
Few studies show any overlap in preferences between young men and women in their video gaming choices. The current study surveyed
over 2,000 college undergraduates for video game experience, preferences, and self-efficacy. Although it was found that men
play video games more often, have had more experience, and feel more confident in their game playing ability, a moderate female
gaming population was found to exist, who also play video games regularly. Almost as many similarities as differences were
found between men and women in their gaming preferences. Suggestions and implications for the video game industry are discussed. 相似文献

Interest in mindfulness-based interventions for children and adolescents is burgeoning, bringing with it the need for validated instruments to assess mindfulness in youths. The present studies were designed to validate among adolescents a measure of mindfulness previously validated for adults (e.g., Brown & Ryan, 2003), which we herein call the Mindful Attention Awareness Scale-Adolescent (MAAS-A). In 2 large samples of healthy 14- to 18-year-olds (N = 595), Study 1 supported a single-factor MAAS-A structure, along with acceptably high internal consistency, test-retest reliability, and both concurrent and incremental validity. In Study 2, with a sample of 102 psychiatric outpatient adolescents age 14-18 years, participants randomized to a mindfulness-based stress reduction intervention showed significant increases in MAAS-A scores from baseline to 3-month follow-up, relative to nonsignificant score changes among treatment-as-usual participants. Increases in MAAS-A scores among mindfulness-based stress reduction participants were significantly related to beneficial changes in numerous mental health indicators. The findings support the reliability and validity of the MAAS-A in normative and mixed psychiatric adolescent populations and suggest that the MAAS-A has utility in mindfulness intervention research. 相似文献

System-wide research on the use of out-of-home care among children and youth is needed to inform the development of policies
and services. We used Medicaid claims from North Carolina to examine patterns of out-of-home care, identify demographic and
diagnostic differences between those who received care in residential treatment, psychiatric hospitals, or general hospitals,
and determine whether demographic or diagnostic characteristics were associated with having more than one out-of-home stay
during the year. Among those who received out-of-home care during a 1 year period, 36% received care in residential treatment
only, 32.4% in general hospitals only, and 17.6% in psychiatric hospitals only, while 14.0% used more than one sector of out-of-home
care. Boys, teenagers, and youth in foster care or diagnosed with emotional disturbance or hyperkinetic syndrome had higher
odds of receiving care in residential treatment only whereas girls, youth age 19–21, and those with depressive and stress
and adjustment disorders had higher odds of receiving care from hospitals only. Teenagers and youth in foster care had higher
odds of having more than one stay. Among those with more than one stay, there were 300 patterns of care and nearly half received
care from more than one service sector. The implications for services and policy are discussed. Further research is needed
to understand patterns of out-of-home care and the factors that influence placement decisions. 相似文献

Event-related potential (ERP) studies have attempted to discover the processes that underlie conscious visual perception by contrasting ERPs produced by stimuli that are consciously perceived with those that are not. Variability of the proposed ERP correlates of consciousness is considerable: the earliest proposed ERP correlate of consciousness (P1) coincides with sensory processes and the last one (P3) marks postperceptual processes. A negative difference wave called visual awareness negativity (VAN), typically observed around 200 ms after stimulus onset in occipitotemporal sites, gains strong support for reflecting the processes that correlate with, and possibly enable, aware visual perception. Research suggests that the early parts of conscious processing can proceed independently of top-down attention, although top-down attention may modulate visual processing even before consciousness. Evidence implies that the contents of consciousness are provided by interactions in the ventral stream, but indispensable contributions from dorsal regions influence already low-level visual responses. 相似文献

In timing perception studies, the timing of one event is usually manipulated relative to another, and participants are asked to judge if the two events were synchronous, or to judge which of the two events occurred first. Responses are analyzed to determine a measure of central tendency, which is taken as an estimate of the timing at which the two events are perceptually synchronous. When these estimates do not coincide with physical synchrony, it is often assumed that the sensory signals are asynchronous, as though the transfer of information concerning one input has been accelerated or decelerated relative to the other. Here we show that, while this is a viable interpretation, it is equally plausible that such effects are driven by shifts in the criteria used to differentiate simultaneous from asynchronous inputs. Our analyses expose important ambiguities concerning the interpretation of simultaneity judgement data, which have hitherto been underappreciated. 相似文献

Temporal conceptualisation and investigation of brain-mind functioning, in health and in neuro-psychiatric disease, is a relatively new field in neuroscience. The cerebellum has long been suspected as the centre for the organization of timing in the brain. This article examines endophenotypes for temporal coding in schizophrenia, centring on aberrant, neuronal, input connectivity to the cerebellum. 相似文献

Individuals diagnosed with major depressive disorder (MDD) often ruminate about their depression and their life situations, impairing their concentration and performance on daily tasks. We examined whether rumination might be due to a deficit in the ability to expel negative information from short-term memory (STM), and fMRI was used to examine the neural structures involved in this ability. MDD and healthy control (HC) participants were tested using a directed-forgetting procedure in a short-term item recognition task. As predicted, MDD participants had more difficulty than did HCs in expelling negative, but not positive, words from STM. Overall, the neural networks involved in directed forgetting were similar for both groups, but the MDDs exhibited more spatial variability in activation in the left inferior frontal gyrus (a region critical for inhibiting irrelevant information), which may contribute to their relative inability to inhibit negative information. 相似文献

Social-networking sites like Facebook enable people to share a range of personal information with expansive groups of "friends." With the growing popularity of media sharing online, many questions remain regarding antecedent conditions for this behavior. Contingencies of self-worth afford a more nuanced approach to variable traits that affect self-esteem, and may help explain online behavior. A total of 311 participants completed an online survey measuring such contingencies and typical behaviors on Facebook. First, exploratory factor analyses revealed an underlying structure to the seven dimensions of self-worth. Public-based contingencies explained online photo sharing (β?=?0.158, p?0.01), while private-based contingencies demonstrated a negative relationship with time online (β?=?-0.186, p?0.001). Finally, the appearance contingency for self-worth had the strongest relationship with the intensity of online photo sharing (β?=?0.242), although no relationship was evident for time spent managing profiles. 相似文献
