The present paper concerns the influence negative emotions exert on motivational processes, i.e., on the selection of goals and corresponding actions. It is assumed that, in a negative emotional state, the goal to overcome this negative mood state takes precedence over the goal to succeed in a nonemotional task. Correspondingly, emotion-related activities should be preferred to task-related ones. In order to test this assumption, subjects in a negative and a neutral emotional state were given a series of activities, some suited for coping, some suited for task fulfilment. They were instructed to name (Experiment I) or to carry out (Experiment II) those activities they preferred at the very moment and to give a short reason for each choice. Results showed that subjects in a negative mood compared to those of the neutral control group were less occupied with the nonemotional task, but instead more frequently chose emotion-related activities with the explicit reason that these activities served to overcome their negative emotions. 相似文献

In psychophysiology all procedures used are accompanied with changes of general activation level (GAL) of the subjects. In our study these changes are characterized by self-assessment of the internal state and by the mean heart rate (HR) of each period. On the basis of these data group mean auditory evoked potentials (AEPs) were computed. The influence of the GAL on the N 110- and P 190-amplitudes of the AEPs was analysed. There was no effect on the P 190-amplitude whereas the N 110-amplitude shows distinct responses on changes in GAL. These amplitudes diminished when the subjects reported a change of internal state. The diminishing of N 110-amplitudes took place as well at an increase as at a decrease of the internal state factors. Comparing the HR and the N 110 of the AEPs we found an inverse U-shaped dependence. These results are discussed in comparison to the literature. Furthermore a model which could elucidate the observed findings is presented for a critical discussion. 相似文献

Four experiments were conducted to demonstrate that embarrassment and shame are distinct emotions that result from violations of different types of internalized standards. Embarrassment results from violating one's particular persona; shame results from violating a shared, objective ideal. Subjects vividly imagined themselves in situations and indicated their emotional reactions. In Experiment I, we demonstrate that people differentiate between embarrassment and shame systematically (F(1,27) = 74.4, p < 0.001). In Experiments 2 and 3, we demonstrate that embarrassment results from violating a persona (n = 34, p < 0.001; n = 23, p < 0.001), and shame results from violating an objective ideal (n = 34, p < 0.001; n = 23, p < 0.001). In Experiment 4, we demonstrate that it is the type of standard that is violated (n = 30, p < 0.001), not whether or not the violation was intentional, that determines whether one experiences embarrassment or shame. We argue that both shame and embarrassment play an important role in maintaining personal identity. 相似文献

This case study concerns an 18-year-old bilingual girl who suffered a radiation lesion in the left (dominant) thalamic and temporal region when she was 4 years old. Language and memory assessment revealed deficits in auditory short-term memory, auditory word comprehension, nonword repetition, syntactic processing, word fluency, and confrontation naming tasks. Both languages (English and Dutch) were found to be affected in a similar manner, despite the fact that one language (English) was acquired before and the other (Dutch) after the period of lesion onset. Most of the deficits appear to be related to verbal (short-term) memory dysfunction. Several hypotheses of subcortical involvement in memory processes are discussed with reference to existing theories in this area. 相似文献

Language impairment was assessed in 33 patients with Alzheimer's disease (AD), in 52 patients with multi-infarct dementia (MID), and in 86 elderly community residents. The investigation included the D-Test Battery based on the Luria's Neuropsychological Investigation for all subjects. An extended battery of Luria's language items was used for 30 demented patients (11 AD and 19 MID patients) and 86 controls. The changes in language functions in normal subjects could be clearly differentiated from those seen in patients with mild dementia. The patients with different degrees of dementia differed also significantly from each other in regard to language impairment. Moreover, patients with AD and MID appeared to have different patterns of language impairment although the severity of dementia and the levels of orientation, mnestic, and conceptual functions were equal. AD was associated especially with a defect in understanding of grammatical structures and MID with disorders in recognition of words, naming, and repetition. The differential diagnostic capacity of 23 selected language items proved to be 97% between AD, MID, and control subjects. The results indicate that the examination of language functions is valuable in the differential diagnosis of dementia. 相似文献

Community treatment for seriously mentally ill individuals fits well into the philosophy of community psychology. Community psychologists have skills and experiences with other populations that represent assets in improving the ACT service model and producing richer and more useful research results for the future. Maybe we should ask ourselves why community psychologists have obviously avoided this intervention area and the population of seriously mentally ill individuals. Does this represent an adolescent reaction to the parent discipline — clinical psychology? Is the label “mentally ill” as stigmatizing to community psychologists as it is to the general population? Are these individuals written off as not worthy of or capable of benefiting from preventive interventions? Advocates for the seriously mentally ill are mounting a backlash against prevention services. We would be well advised at this time to become involved in community treatment and demonstrate that community psychology is forall vulnerable and at-risk population groups. If the truth of the matter is that “community psychology is not doing much of a job of empowering people” (Berkowitz, 1990), maybe the truth of the matter is also that we need to reach out to more disenfranchised populations with research to show that community psychologycan do the job of empowering some. 相似文献

AIDS prevention for intravenous drug users in the community: Street-based education and risk behavior 总被引:2,自引:0,他引:2

Conducted a study of behavior change associated with a street-based AIDS education project targeted to intravenous (IV) drug users in San Francisco. Two cross-sections were sampled from drug detoxification clinics and street locations in 1986 (n = 438) and 1987 (n = 623). Significant increases were reported in the percentage of IV drug users who used bleach to decontaminate syringes, who did not share needles in past year, and in condom use. A significant reduction in an index of the number of needle-sharing partners was reported. Respondents ranked treatment program as most important source of AIDS information prior to implementation of the program, and ranked outreach workers as most important after implementation. Findings suggest that this community-based outreach program had at least some impact on knowledge about AIDS and may have led to reductions in behaviors known to transmit HIV. 相似文献

Previous research has tentatively indicated that coercive, ineffective parenting might have a mediating role in the differential impact of marital discord on boys and girls. To further explore this role, we examined the relationship between children's perceptions of marital discord and their evaluations of parental discipline techniques. Ninety-one children aged 8 to 13 years (mean age: 11 years 4 months) were split into high, moderate, and low perceived marital discord on the basis of their responses to the Children's Perceptions Questionnaire (Emery & O'Leary, 1982). The children rated how coercive they believed both mothers and fathers would and should be in three discipline situations. Children with high marital discord indicated that both mothers and fathers would and should use more coercive behavior than did children with low marital discord. The effects of marital discord were stronger for boys than for girls. All children also believed that fathers would and should be more coercive than mothers. Results are discussed in relation to the effects of marital discord on children's social development with regard to sex of the child.Thanks are due to Mike Siegal and Pat Noller for their helpful comments on previous drafts. 相似文献

Identification of a fixated object in a visual display is facilitated by integrating information from a preview of that object in the periphery with information extracted on the subsequent foveal fixation (Pollatsek, Rayner, & Collins, 1984). These experiments investigated the extent to which this integration is dependent on the spatial location of the information remaining constant. Two preview objects were presented in the periphery; Ss fixated that region and named a single target object that appeared in the same spatial location in which one of the two preview objects had been presented. Of primary interest was the facilitative effect when a preview object was identical to the target object as a function of whether they were in the same spatial location. The major finding was that although there was a small effect of switching, there was still a substantial preview benefit even when the location of the identical object switched. In addition, the switching effect did not interact with the level of identity between the preview and target. There was also a preview benefit in conditions in which there were no eye movements and the preview and target objects were at least 5 degrees apart. Thus, the data indicate that the process object identification is relatively insensitive to location information and that object information and location information are coded fairly independently. 相似文献

Sperling, Landy, Dosher, and Perkins (1989) argued that all previous research on the kinetic depth effect has been contaminated by stimulus artifacts, and they developed a new task that they believe can successfully overcome this problem. The present discussion offers a counter-argument that artifacts are not as pervasive in previous research as Sperling et al. imply and that their proposed method is subject to precisely the same limitations as earlier studies. Also discussed are some general guidelines of experimental design in this type of research to minimize the possibility that subjects will adopt an inappropriate response strategy that does not truly reflect their visual perceptions of three-dimensional form. 相似文献
