Recent studies reported converging evidence for action–effect associations if participants adopted an intention-based action
control mode in free choice conditions, whereas no evidence for action–effect associations was found when participants adopted
a stimulus-based mode in forced choice conditions. However, it is not yet clear whether action control modes moderate acquisition
or usage of action–effect associations. In the present experiment, two groups of participants underwent an acquisition phase
consisting of either free or forced choice key presses that produced irrelevant, but contingent effect tones. In a subsequent
test phase, participants freely chose the key to press after former effect tones were presented. A reliable consistency effect
resulted for both the groups, i.e. participants preferred the key that produced the irrelevant tone in the preceding acquisition
phase. In combination with prior findings, this consistency effect suggests that usage, but not acquisition of action–effect
associations depends on an intention-based action control mode. 相似文献

Fatigue is a serious cancer-related syndrome reported by cancer patients during and after treatment. Especially the impact of chronic fatigue on quality of life is substantial. The aim of this study was to identify predictors of fatigue after finishing treatment from an early stage of the cancer treatment. A sample of 551 cancer patients with heterogeneous diagnoses completed questionnaires assessing fatigue, psychological and psychosomatic data plus treatment data. The patients were recruited from an acute care hospital (t1) and the participants completed the questionnaire 2?C2.5 years after treatment (t2). Regression analysis showed that the strongest predictor of later fatigue was fatigue during the therapy. Other impact factors are radiotherapy and pain. The results suggest that the diagnosis and treatment of acute fatigue should be carried out at an early stage of cancer treatment to prevent chronic fatigue. Suitable diagnostic methods and treatment options will be presented. 相似文献

In two experiments, ostracized individuals showed more pronounced categorical perception of inclusion- and exclusion-related stimuli. Specifically, ostracism enhanced the ability to distinguish between-category differences (e.g., between happy and angry faces) relative to within-category differences (e.g., between two happy expressions). Participants were socially included or excluded via Cyberball (a virtual ball-tossing task). In Experiment 1, ostracized participants showed greater perceptual acuity in distinguishing between subtly happy and angry expressions combined with a reduced ability to discriminate expressions within each expression category. Experiment 2 found analogous categorical perception effects for targets varying on the dimension of race. Importantly, this effect was specific to social information; categorical perception of non-social objects was not qualified by social exclusion. These results suggest that ostracism exacerbates categorical perception, attuning perceivers to the differences between various inclusion- and exclusion-related categories relative to within category acuity, making the world appear more ‘black-and-white’ than it might otherwise. 相似文献

Two samples of Hong Kong college students completed the English and the Chinese version of the Multidimensional Orientation Toward Dying and Death Inventory (MODDI-F), respectively. Results show substantially lower coefficients of internal consistency in the English version when compared with its Chinese counterpart. The construct validity of the instrument, i.e., the statistical relationships between its subtests, was confirmed. Whenever available, the use of a questionnaire that is worded in the participants' mother tongue is recommended. 相似文献

Background
So far only few studies are available which have evaluated the effectiveness of psychoeducation for individuals at risk of psychosis in the early initial prodromal state (EIPS) whereas the benefit of psychoeducation in psychotic patients has been repeatedly confirmed. Thus the aim of this study was to investigate the effect of psychoeducation in individuals with increased risk of psychosis in the EIPS.Method
A total of 128 help-seeking outpatients in the EIPS participated in a randomized controlled multicentre trial of 12 months of either psychoeducation as part of an integrated psychological intervention (IPI) or supportive counseling (SC). The time to transition to psychosis at 12-month and 24-month follow-up as well as the social adjustment at baseline, time of transition or post-treatment by means of the social adjustment scale (SAS?II) were assessed.Results
The IPI was superior to SC in preventing progression to psychosis at 12-month (3.2% versus 16.9%, p?=0.008) and 24-month follow-up (6.3% versus 20.0%, p?=0.019). Both treatments resulted in significant pre-post improvements in SAS?II with no significant differences between the two groups.Conclusions
Psychoeducation as part of an integrated intervention is effective for preventing the onset of psychosis over a 24-month time period in people in an EIPS. Moreover patients at risk of developing first episode psychosis seem to benefit from a specific psychoeducational intervention in the context of other treatments as well as from SC. 相似文献356.
Solar water disinfection (SODIS) is a sustainable method of water treatment. Despite the simplicity and many advantages of SODIS, past behaviour change campaigns have seen limited success. This study aims to compare intervention strategies in their efficiency in changing behaviour and to analyse which behavioural factors are differentially affected. The following factors were analysed in this study: intention, subjective norm, behavioural control, beliefs, habits, frequency of talking, knowledge and tension. The promotion strategies used in this intervention study were promoters, a pass‐on task, prompts, public commitment and disseminating knowledge with inducing tension. Inhabitants of high‐density areas near Harare, Zimbabwe, were interviewed at different points in time. High SODIS consumption was achieved when the promoter intervention was followed by a memory‐aiding technique such as prompts or public commitment. Consequently, this combined‐intervention strategy increased all behavioural factors and kept them at a high level. A continued pass‐on task alone did not change behaviour and had decreasing effects on several behavioural factors. When the pass‐on task was combined with disseminating knowledge with inducing tension, high SODIS water consumption was also reached, but several behavioural factors stayed at a low level. More effective intervention strategies are identified and discussed. 相似文献

Substantial evidence suggests that test anxiety is associated with poor performance in complex tasks. Based on the differentiation of coordinative and sequential demands on working memory (Mayr & Kliegl, 1993), two studies examined the effects of sequential demands on the relationship between test anxiety and cognitive performance. Both studies found that high sequential demands had beneficial effects on the speed and accuracy of the performance of test-anxious participants. It is suggested that the more frequent memory updates associated with high sequential demands may represent external processing aids that compensate for the restricted memory capacity of individuals with high test anxiety. 相似文献
