A comparison was made between two procedures for teaching persons with severe handicaps: (a) the task demonstration model, which is based upon a fading procedure and general case programming, and (b) the standard prompting hierarchy, a least-to-most intrusive prompting procedure commonly used to teach these individuals. Five phases were used in comparing the procedures: pretesting, training, two generalization tests, and a 6-month maintenance test. Eight students learned two discrimination tasks by each procedure, with each task involving two- or three-digit numbers. Results showed that under the task demonstration model all 8 subjects had more unprompted correct responses (about 1.5 times as many) in training, all 8 subjects had fewer errors (about 0.6 times as many) in training, all 8 subjects had more correct responding in the generalization test with untrained stimuli in the training room, 6 of 8 subjects had more correct responding with untrained stimuli in another room, a 7th had equivalent amounts, and 7 of 8 subjects had more correct responding on a 6-month maintenance test. Thus, the task demonstration model proved superior to the standard prompting hierarchy in 29 of 32 tests of correct responding. Results are discussed in terms of implications for stimulus control training strategies. 相似文献

Based on the Social Simulation Theory of dreaming (SST), we studied the effects of voluntary social seclusion on dream content and sleep structure. Specifically, we studied the Compensation Hypothesis, which predicts social dream contents to increase during social seclusion, the Sociality Bias – a ratio between dream and wake interactions – and the Strengthening Hypothesis, which predicts an increase in familiar dream characters during seclusion. Additionally, we assessed changes in the proportion of REM sleep. Sleep data and dream reports from 18 participants were collected preceding (n = 94), during (n = 90) and after (n = 119) a seclusion retreat. Data were analysed using linear mixed-effects models. We failed to support the Compensation Hypothesis, with dreams evidencing fewer social interactions during seclusion. The Strengthening Hypothesis was supported, with more familiar characters present in seclusion dreams. Dream social interactions maintained the Sociality Bias even under seclusion. Additionally, REM sleep increased during seclusion, coinciding with previous literature and tentatively supporting the proposed attachment function for social REM sleep. 相似文献

How humans perform duration judgments with multisensory stimuli is an ongoing debate. Here, we investigated how sub-second duration judgments are achieved by asking participants to compare the duration of a continuous sound to the duration of an empty interval in which onset and offset were marked by signals of different modalities using all combinations of visual, auditory and tactile stimuli. The pattern of perceived durations across five stimulus durations (ranging from 100 ms to 900 ms) follows the Vierordt Law. Furthermore, intervals with a sound as onset (audio-visual, audio-tactile) are perceived longer than intervals with a sound as offset. No modality ordering effect is found for visualtactile intervals. To infer whether a single modality-independent or multiple modality-dependent time-keeping mechanisms exist we tested whether perceived duration follows a summative or a multiplicative distortion pattern by fitting a model to all modality combinations and durations. The results confirm that perceived duration depends on sensory latency (summative distortion). Instead, we did not find evidence for multiplicative distortions. The results of the model and the behavioural data support the concept of a single time-keeping mechanism that allows for judgments of durations marked by multisensory stimuli. 相似文献

Recovery from work protects employees’ health and well-being, and therefore it is important to understand its antecedents. The aim of this study conducted among 183 middle-aged participants drawn from the Finnish Jyväskylä Longitudinal Study of Personality and Social Development was to examine whether job skill discretion and emotion control strategies (emotional rumination and emotional inhibition) are related to psychological aspects of recovery from work (subjective recovery evaluation, psychological detachment and relaxation). The results of hierarchical general linear models confirmed the hypothesis that job skill discretion is positively associated with subjective recovery evaluation and relaxation. As expected, high emotional rumination predicted difficulties in psychological detachment and relaxation. Emotional inhibition moderated the relationship between job skill discretion and psychological detachment: where emotional inhibition was at a moderate level, job skill discretion was positively related to psychological detachment. The findings suggest that not only job characteristics but also individual factors contribute to recovery, revealing practical implications for employees, employers and occupational health care professionals seeking to promote employees’ work ability, health and well-being. 相似文献

The present study investigated whether the facial expression of the social emotion schadenfreude, the pleasant emotion which arises in response to another’s misfortune, can be differentiated from the facial expression of joy. Schadenfreude was induced by videos displaying unsuccessful penalty shots of Dutch soccer players and joy by successful penalty shots of German soccer players. Thirty-two participants watched videos while the activity of four facial muscles was recorded electromyographically. Furthermore, they judged each stimulus according to valence, arousal, joy, schadenfreude and sadness. Electromyography (EMG) results revealed that schadenfreude expressions did not differ from joy with regard to involved muscles (increase of Musculus zygomaticus major and M. orbicularis oculi activity, decrease of M. corrugator supercilii activity, no activity change of M. frontalis medialis). Furthermore, facial reactions developed fast in both conditions and EMG indicated stronger reactions in the schadenfreude condition, but according to ratings participants felt more pleasure in the joy condition. 相似文献

The deterioration of performance over time is characteristic for sustained attention tasks. This so-called “performance decrement” is measured by the increase of reaction time (RT) over time. Some behavioural and neurobiological mechanisms of this phenomenon are not yet fully understood. Behaviourally, we examined the increase of RT over time and the inter-individual differences of this performance decrement. On the neurophysiological level, we investigated the task-relevant brain areas where neural activity was modulated by RT and searched for brain areas involved in good performance (i.e. participants with no or moderate performance decrement) as compared to poor performance (i.e. participants with a steep performance decrement). For this purpose, 20 healthy, young subjects performed a carefully designed task for simple sustained attention, namely a low-demanding version of the Rapid Visual Information Processing task. We employed a rapid event-related functional magnetic resonance imaging (fMRI) design. The behavioural results showed a significant increase of RT over time in the whole group, and also revealed that some participants were not as prone to the performance decrement as others. The latter was statistically significant comparing good versus poor performers. Moreover, high BOLD-responses were linked to longer RTs in a task-relevant bilateral fronto-cingulate-insular-parietal network. Among these regions, good performance was associated with significantly higher RT-BOLD correlations in the pre-supplementary motor area (pre-SMA). We concluded that the task-relevant bilateral fronto-cingulate-insular-parietal network was a cognitive control network responsible for goal-directed attention. The pre-SMA in particular might be associated with the performance decrement insofar that good performers could sustain activity in this brain region in order to monitor performance declines and adjust behavioural output. 相似文献

Associations between personality traits and psychological well-being across time in middle adulthood
Associations of personality traits with psychological well-being (PWB) were analyzed across ages 33–50 as part of an ongoing Finnish longitudinal study (initial N = 369). Bivariate latent growth curve analyses indicated that a low initial level of neuroticism (.75) and high extraversion (.55) correlated strongly with a high level of PWB. Moreover, a high level of conscientiousness, openness, and agreeableness also correlated significantly with PWB. The change factor was significant only for openness: the higher the initial level of PWB, the higher the increase in openness from age 33–50. In comparison with emotional well-being, indicated by general life satisfaction, the associations of the personality traits with PWB were significantly stronger for neuroticism, extraversion, and openness. 相似文献

Social desirability has been shown to be stable in samples with higher school education. However, little is known about the stability of social desirability in more heterogeneous samples differing in school education. This study aimed to investigate the stability of social desirability and which factors predict interindividual differences in intraindividual change. As part of a randomized controlled trial, 1,243 job seekers with unhealthy alcohol use were systematically recruited at three job agencies. A total of 1,094 individuals (87.8%) participated in at least one of two follow‐ups (6 and 15 months after baseline) and constitute this study's sample. The Social Desirability Scale‐17 was applied. Two latent change models were conducted: Model 1 tested for interindividual differences in intraindividual change of social desirability between both follow‐ups; Model 2 included possible predictors (age, sex, education, current employment status) of interindividual differences in intraindividual change. Model 1 revealed a significant decrease of social desirability over time. Model 2 revealed school education to be the only significant predictor of change. These findings indicate that stability of social desirability may depend on school education. It may not be as stable in individuals with higher school education as in individuals with lower education. 相似文献

The metaphor of the cognitive miser is a milestone in the development of social cognitive research. It highlights the limited cognitive resources of the social thinker and the demand for fast and efficient processing of information. In marked contrast to the impact of this metaphor on social cognition research in general, it has so far been mostly overlooked in research on social comparison. In this article we want to lay out the potential of social comparison research if one takes on the perspective of a cognitive miser. Specifically, we consider social comparison as a heuristic for evaluating the self. First, we look for evidence for the ease of comparative self-evaluations. Second, we analyse the standard selection process and identify routine standards that facilitate the comparison process. Third, we investigate the cognitive mechanisms in social comparisons and suggest that comparison mechanisms leading to assimilation are more efficient than mechanisms leading to contrast effects. 相似文献
