This study used two measures of cohesion for the process analysis of 12 short-term, time-limited groups for complicated grief. The measures had similar theoretical definitions but differed in terms of rater source (member vs. observer), measurement score (mean of items vs. global rating), and rating unit (individual vs. group). We examined the relationship between the measures, assessed the development of cohesion over the life of the group, and evaluated each measure's relationship to outcome. A principal components analysis with each measure yielded one cohesion component, which supported a unidimensional model; however, the two cohesion components were independent of each other, which supported a multidimensional model. Repeated measures analyses indicated that observer-rated cohesion developed in a quadratic manner (v pattern) across sessions, while member-rated cohesion developed in a linear manner. The object focus (the group, other members, the therapist) of the members' ratings determined whether cohesion increased or decreased across sessions. No significant relationships between cohesion and outcome were identified. Implications of the findings for the understanding of group cohesion are considered. 相似文献

Atypical depression: enhanced right hemispheric dominance for perceiving emotional chimeric faces 总被引:2,自引:0,他引:2
Bruder GE Stewart JW McGrath PJ Ma GJ Wexler BE Quitkin FM 《Journal of abnormal psychology》2002,111(3):446-454
Two studies compared hemispatial bias for perceiving chimeric faces in patients having either atypical or typical depression and healthy controls. A total of 245 patients having major depressive disorder (MDD) or dysthymia (164 with atypical features) and 115 controls were tested on the Chimeric Faces Test. Atypical depression differed from typical depression and controls in showing abnormally large right hemisphere bias. This was present in patients having either MDD or dysthymia and was not related to anxiety, physical anhedonia, or vegetative symptoms. In contrast, patients having MDD with melancholia showed essentially no right hemisphere bias. This is further evidence that atypical depression is a biologically distinct subtype and underscores the importance of this diagnostic distinction for neurophysiologic studies. 相似文献

Olivopontocerebellar atrophy (OPCA) is a still debated condition, of which motor disruption is the most common feature. A high incidence of associated mood disorders may exist, but there are few studies on concomitant cognitive impairment. Our aim was to assess whether there is reading and writing disruption in olivopontocerebellar atrophy (OPCA). 6 patients were administered different reading and writing tasks. Scores were then compared to those obtained by healthy volunteers. There was an evident impairment in reading and writing execution in our patients compared to those of the control group. On the contrary, no difference could be found in abstraction, problem-solving, and memory tasks. We discuss the results, debating the role of the cerebellum in the conscious process of cognition or in ocular movement control (necessary for reading and writing fluidity and effective execution) and in the dynamic activation of all the cerebral cortex mediated by the diffuse projection to the reticular system. 相似文献

The contextual modulation of conditioned taste aversions by the physical environment and time of day is similar 下载免费PDF全文

In a pair of experiments, we have compared the ability of changes of place (Exp. 1) and changes of time of day (Exp. 2) to separately modulate learned saline-aversion memory phenomena in rats. Neither a spatial nor a temporal change disrupted latent inhibition using the present behavioral procedure. However, pre-exposure to the taste increased the contextual control of the learned aversion expression. The aversion reappeared in the place or at the time of conditioning after extinction in a different context. The results indicate that environmental and temporal contexts can independently, but similarly modulate taste aversion learning. 相似文献

This study examined whether Asian American-White American differences on a trait measure of social anxiety extend to nonverbal behavior and to reports of anxiety-related emotions during a 3-min social performance task. Forty Asian Americans and 40 White Americans completed a trait measure of social anxiety and rated their emotions before, and immediately after, a social performance task. Their videotaped behavior was coded using microlevel behavioral codes (e.g., gaze avoidance, fidgeting). Results indicated that Asian Americans reported more anxiety than White Americans on the trait measure and on the emotion rating scales but that they did not differ substantially on microlevel behavioral indexes of social anxiety. Implications of ethnic variations in the patterns of anxious responding are discussed. 相似文献

Existing transformational leadership research has focused primarily on the behaviors of leaders and their effects on followers. The authors extended this research by examining the social networks of managers who exhibit transformational leadership behaviors. Their focus was on the network of relationships that managers develop and whether they hold key positions in the organization's informal social networks. In a field study using data from 39 managers and 130 nonmanagement employees of 6 organizations, the authors found that managers who score higher on transformational leadership tend to hold more central positions in organizational advice and influence networks. Furthermore, the direct reports of these leaders were also more central in informal organizational networks. These results illuminate one of the ways that managers who exhibit transformational leadership behaviors may exert influence in organizations. 相似文献

Expression of the immediate-early gene-encoded protein Egr-1 (zif268) during in vitro classical conditioning 下载免费PDF全文
Expression of the immediate-early genes (IEGs) has been shown to be induced by activity-dependent synaptic plasticity or behavioral training and is thought to play an important role in long-term memory. In the present study, we examined the induction and expression of the IEG-encoded protein Egr-1 during an in vitro neural correlate of eyeblink classical conditioning. The results showed that Egr-1 protein expression as determined by immunocytochemistry and Western blot analysis rapidly increased during the early stages of conditioning and remained elevated during the later stages. Further, expression of Egr-1 protein required NMDA receptor activation as it was blocked by bath application of AP-5. These findings suggest that the IEG-encoded proteins such as Egr-1 are activated during relatively simple forms of learning in vertebrates. In this case, Egr-1 may have a functional role in the acquisition phase of conditioning as well as in maintaining expression of conditioned responses. 相似文献

The aim of this study is to analyze how the length of time a patient spends in an Intensive Care Unit (ICU) affects close relatives, with regard to specific clinical variables of personality, family relationships and fear of death. The study group consisted of 57 relatives of seriously ill patients admitted to the ICU of "Virgen del Rocío" Rehabilitation and Trauma Hospital (Seville, Spain). The instruments applied were: a psychosocial questionnaire, clinical analysis questionnaire, family environment scale and fear of death scale. The relatives of patients admitted to ICU obtained higher scores in hypochondria, suicidal depression, agitation, anxious depression, guilt-resentment, paranoia, psychasthenia, psychological maladjustment and self-expression, and less in fear of their own death, as when compared to interviews with the same relatives 4 years later. The length of time a patient spent in the ICU influenced relatives in some clinical variables of personality, family relationships and fear of death 相似文献

In order to investigate the body image self-perception and the prevalence of body dissatisfaction among Chinese children and adolescents, 9100 children aged 3-15 years living in four cities completed a questionnaire assessing body image self-percepts and ideals by figural stimuli. The results indicate that (1) children's body ratings started to be significantly related to their BMIs at age 5 and correlations increased with age; (2) a wide range of current body sizes was chosen by Chinese boys and girls; (3) the ideal body sizes of boys and girls selected by boys and girls, respectively, were "boys by boys">"boys by girls">"girls by boys">"girls by girls" and (4) the satisfaction, mild dissatisfaction, and moderate dissatisfaction rates were 40.1%, 36.4% and 23.5%, respectively. Differences as a function of gender and age were identified. It was concluded that the prevalence of body dissatisfaction among children and adolescents of urban China was striking, and that the Chinese boys were not immune to body dissatisfaction. 相似文献

An important source of people's perceptions of their performance, and potential errors in those perceptions, are chronic views people hold regarding their abilities. In support of this observation, manipulating people's general views of their ability, or altering which view seemed most relevant to a task, changed performance estimates independently of any impact on actual performance. A final study extended this analysis to why women disproportionately avoid careers in science. Women performed equally to men on a science quiz, yet underestimated their performance because they thought less of their general scientific reasoning ability than did men. They, consequently, were more likely to refuse to enter a science competition. 相似文献
