In four experiments employing between-list designs, generation was found to have negative effects on free recall of word pairs and on cued recall of the second word. In addition, generation had negative effects on measures of word-pair integration and on clustering in recall. In contrast, positive effects of generation were found on free recall of second words alone, and on a recognition test for memory of the second word. It was concluded that in between-list designs, generation led to greater individual-item processing of the generated term than reading, but this processing occurred at the expense of processing the relation between the words in a pair and processing the relations between different pairs in a list.  相似文献

Despite the vastly increased dissemination of the low-intensity (LI) version of cognitive behavior therapy (CBT) for the treatment of anxiety and depression, no valid and reliable indices of the LI-CBT clinical competencies currently exist. This research therefore sought to develop and evaluate two measures: the low-intensity assessment competency scale (LIAC) and the low-intensity treatment competency scale (LITC). Inductive and deductive methods were used to construct the competency scales and detailed rating manuals were prepared. Two studies were then completed. The first study used a quantitative, fully-crossed design and the second a multi-center, quantitative longitudinal design. In study one, novice, qualified, and expert LI-CBT practitioners rated an LI-CBT assessment session (using the LIAC) and an LI-CBT treatment session (using the LITC). Study two used the LIAC and LITC across four training sites to analyze the competencies of LI-CBT practitioners over time, across raters, and in relation to the actor/patients’ feedback concerning helpfulness, the alliance, and willingness to return. Both the LIAC and LITC were found to be single factor scales with good internal, test-retest reliability and reasonable inter-rater reliability. Both measures were sensitive to measuring change in clinical competence. The LIAC had good concurrent, criterion, discriminant, and predictive validity, while the LITC had good concurrent, criterion, and predictive validity, but limited discriminant validity. A score of 18 accurately delineated a minimum level of competence in LI-CBT assessment and treatment practice, with incompetent practice associated with patient disengagement. These observational ratings scales can contribute to the clinical governance of the burgeoning use of LI-CBT interventions for anxiety and depression in routine services and also in the methods of controlled studies.  相似文献

The present research studied self-awareness by utilizing experiential sampling methodology, which allows for the random sampling of individuals' thoughts and feelings as they go about their normal daily activities. Neither Study 1 nor 2 found a relation between private or public self-awareness and negative affect. However, attention to private self-aspects was generally more positive and less ruminative for low as opposed to high private self-conscious subjects, and awareness of oneself as a social object was generally more positive but less important for low as opposed to high public self-conscious subjects. What may have accounted for the negative relation between private self-consciousness and average affect was that low private self-conscious subjects were more likely to attend to their private self-aspects if they were pleasant than if they were unpleasant, while high private self-conscious subjects' degree of private self-awareness was unrelated to whether the content of this state was pleasant or not. These findings are consistent with the hypothesis that low private self-conscious individuals engage in a more selective type of self-attention when in the private self-aware state than do high private self-conscious individuals. Regarding the relation between self-awareness and social context, both studies found that the presence of others results in a heightened public self-awareness. However, even though subjects were more attentive to public self-aspects when with others than when alone, in general, they were more attentive to their “private self” than to their “public self”. Results are discussed in terms of current self-awareness theory.  相似文献

This article summarizes the current understanding of the condition known asguruitis. A general picture of the etiology, prognosis, and treatment of this illness is presented. Guruitis emerges as a multifactorial, nonlethal, widespread professional disease. The illness essentially involves the idealization of some professional figure who may have varying degrees of closeness with a larger theoretical base or orientation, but whose personal attributes interact with those of the potential victim, thus producing onset of the disease.  相似文献

The theory that the subjective experience of crowding results from an attribution of arousal process was examined. Specifically, it was predicted that subjects who were aroused by having their personal space violated would experience less crowding if they were led to believe that some other environmental factor was responsible for the arousal. Groups of subjects were placed in a room in which their personal space was either violated or not violated. Some subjects were told that either an arousing or a relaxing subliminal noise would be played into the room. (Actually there was no noise.) Other subjects were told nothing about subliminal noise. The subjects worked on a number of tasks and were then asked to report how crowded they felt. The noise manipulation had no effect on subjects' performance nor on feelings of crowdedness when their personal space was not being violated. However, when there was a violation of personal space, subjects who felt the noise would arouse them reported being less crowded and performed better than subjects in the relaxing noise or no explanation conditions. It was suggested that subjects attributed their arousal to the “arousing noise” and hence felt less crowded.  相似文献

This article examines the psychological impact of participating in sigmoidoscopy screening for colorectal cancer prevention. The 1st study examined psychological well-being at 3 months, in relation to screening outcome, in 4,153 individuals. The 2nd study used longitudinal data to examine changes in psychological functioning from before to after screening in relation both to screening outcome and baseline indicators of vulnerability. There were few psychological differences between those who had received negative results or had polyps detected. These findings were confirmed in the longitudinal study, which also found no evidence for vulnerability to adverse effects among those who were initially most anxious or who perceived their risk of cancer to be higher. The longitudinal data suggested that screening might produce transient positive effects.  相似文献

This investigation examined how computer‐mediated communication (CMC) partners exchange personal information in initial interactions, focusing on the effects of communication channels on self‐disclosure, question‐asking, and uncertainty reduction. Unacquainted individuals (N = 158) met either face‐to‐face or via CMC. Computer‐mediated interactants exhibited a greater proportion of more direct and intimate uncertainty reduction behaviors than unmediated participants did, and demonstrated significantly greater gains in attributional confidence over the course of the conversations. The use of direct strategies by mediated interactants resulted in judgments of greater conversational effectiveness by partners. Results illuminate some microstructures previously asserted but unverified within social information processing theory (Walther, 1992), and extend uncertainty reduction theory (Berger & Calabrese, 1975) to CMC interaction.  相似文献
