A dynamic model of affect suggests that positive and negative affect (PA and NA) are normally relatively independent of one another, whereas the heightened apprehensiveness and narrowed cognitive attention in persons with anxiety may contribute to a more unidimensional affect structure. This possibility was examined in a sample of 230 patients seeking treatment for anxiety and depressive disorders in the Netherlands. Two methods, a multiple-group confirmatory factor analysis (CFA) and Fisher's z test of correlations, were used to test these predicted relationships within a sample of persons diagnosed with either a depressive or an anxiety disorder. Both methods supported these predictions, with the depressed group exhibiting relatively independent PA and NA while the anxious group's affects were more strongly inversely correlated.  相似文献

Research suggests that exposure to mass media depicting the thin-ideal body may be linked to body image disturbance in women. This meta-analysis examined experimental and correlational studies testing the links between media exposure to women's body dissatisfaction, internalization of the thin ideal, and eating behaviors and beliefs with a sample of 77 studies that yielded 141 effect sizes. The mean effect sizes were small to moderate (ds = -.28, -.39, and -.30, respectively). Effects for some outcome variables were moderated by publication year and study design. The findings support the notion that exposure to media images depicting the thin-ideal body is related to body image concerns for women.  相似文献

Subjects pointed blindfolded at auditory targets before and after exposure to spatial conflict between the sound of a percussion instrument and images on a TV screen. Four experimental conditions were obtained by combining two levels of realism, in which sound was paired with either the image of the hands playing the instrument or with synchronously modulated light, and two levels of suggestion, in which a dummy loudspeaker from which the subjects had been told the sound would come was placed either in front of the TV screen or on top of the actual hidden loudspeaker. Adaptation occurred in all four conditions, but no difference between them was detected. These results confirm and extend the previous finding that auditory adaptation, unlike the impression of fusion (ventriloquism), is little influenced by cognitive factors.  相似文献

In what way is the bereavement process following suicide different from other types of bereavement? The participants were 30 survivors of suicide and 30 survivors of car accidents who were interviewed twice at an average of six months, and the second measure was taken at an average of nine months after the death, with standardized questionnaires to measure depression and grief reaction. Measures of shame, social support, family adaptation, psychological distress, and prior losses were also obtained during the second interview. All survivors were parents who had lost a son aged between 18 and 35 years. The results indicate that suicide survivors were more depressed than accident survivors at the first measure but this difference disappeared at the second measure. Survivors of suicide experienced greater feelings of shame and had experienced more life events after the death than did accident survivors. There was also a greater history of loss in parents bereaved by suicide. Parental bereavement after suicide appears to differ in several ways from other types of bereavement and appears to happen more often in vulnerable families.  相似文献

To clarify the relationship between sexual communication and sexual behavior, multiple components of sexual messages recalled from child hood were examined in a community sample of 248 African-American and White women. Respondents were matched on a predesignated set of demographic variables and were interviewed using the Wyatt Sexual History Questionnaire. We anticipated that women's recollections of messages from parents and television would differ both individually and across ethnicity, and that messages recalled from parents would be multidimensional, varying in tone (positive vs. negative) across time (childhood vs. adolescence) and form (verbal vs. nonverbal). We also expected that the presence and tone of specific types of messages re called would be associated with risk-related sexual behavior. Results confirmed predictions concerning differential interpretations of messages, and ethnicity emerged as a strong mediating variable. The implications of the specific types of parental messages influencing behavior are discussed.  相似文献

Based on a model that combines existing organizational stress theory and job transition theory, this 2-year longitudinal study examined antecedents and consequences of turnover among Dutch truck drivers. For this purpose, self-reported data on stressful work (job demands and control), psychological strain (need for recovery after work and fatigue), and turnover were obtained from 820 drivers in 1998 and 2000. In agreement with the model, the results showed that strain mediates the influence of stressful work on voluntary turnover. Also in conformity with the model, job movement to any job outside the trucking industry (i.e., interoccupational turnover) resulted in a larger strain reduction as compared to job movement within the trucking industry (intraoccupational turnover). Finally, strain was found to stimulate interoccupational turnover more strongly than it stimulated intraoccupational turnover. These findings provide a thorough validation of existing turnover theory and give new insights into the turnover (decision) process.  相似文献

The relations among articulation accuracy, speech perception, and phoneme awareness were examined in a sample of 97 typically developing children ages 48 to 66 months. Of these 97 children, 46 were assessed twice at ages 4 and 5 years. Children completed two tasks for each of the three skills, assessing these abilities for the target phoneme /r/ and the control phoneme /m/ in the word-initial position. Concurrent analyses revealed that phoneme-specific relations existed among articulation, awareness, and perception. Articulation accuracy of /r/ predicted speech perception and phoneme awareness for /r/ after controlling for age, vocabulary, letter-word knowledge, and speech perception or phoneme awareness for the control phoneme /m/. The longitudinal analyses confirmed the pattern of relations. The findings are consistent with a model whereby children's articulation accuracy affects preexisting differences in phonological representations and, consequently, affects how children perceive, discriminate, and manipulate speech sounds.  相似文献

This article discusses the self-in-relation theory as it applies to chemically dependent women. The theory provides an alternative way of understanding and viewing chemically dependent women. The self-in-relation model (or theory) states that relationships are extremely important in women's psychological development and functioning and that women's connection with others is fundamental to self-concept. Women for Sobriety, a mutual help group for chemically dependent women, offers an alternative way of supporting women in trying to achieve recovery, and this is also discussed in a relational context.  相似文献

This study deals with information management and reference encoding modes in oral discourse production. Three potentially influential factors were the distance between the first occurrence of an item and its later occurrences, a topic change that takes the focus off that item, and the span of the conceptual information available for verbalization. French-speaking adult subjects were asked to tell stories from comic strips to a listener who was unfamiliar with them. The frames in each strip were presented simultaneously or in succession. Four versions were generated for each comic strip: a given version was either short (three frames) or long (eight frames), and either did or did not have a topic change. The results showed that the target character was usually marked as a given, regardless of the version. This was more often true, however, when the topic did not change. When the character was treated as a given, referent accessibility marking was dependent on (1) topic change alone when the frames were presented simultaneously, and (2) topic change and comic strip length when the frames were presented in succession. The discussion analyzes the results in terms of the allocation of cognitive resources to maintaining coreference and to assisting addressees in their processing.  相似文献
