Mentally contrasting a desired future with impeding reality promotes goal pursuit when expectations of success are high and curbs goal pursuit when expectations of success are low. Four studies tested whether mental contrasting affects responses to goal-relevant negative feedback. Mental contrasting promoted the processing of negative feedback (Studies 1 and 2), which in turn helped participants to form plans beneficial for goal pursuit (Study 2). Mental contrasting also protected the self-view of competence against negative feedback (Study 3) and facilitated beneficial attributions for negative feedback (Study 4). All effects occurred in line with expectations of success. These results suggest that mental contrasting regulates effective responses to negative feedback by bringing goal pursuit in line with expectations of success. 相似文献

Increasing amounts of data are collected in sports due to technological progress. From a typical soccer game, for instance, the positions of the 22 players and the ball can be recorded 25 times per second, resulting in approximately 135.000 datasets. Without computational assistance it is almost impossible to extract relevant information from the complete data. This contribution introduces a hierarchical architecture of artificial neural networks to find tactical patterns in those positional data. The results from the classification using the hierarchical setup were compared to the results gained by an expert manually classifying the different categories. Short and long game initiations can be detected with relative high accuracy leading to the conclusion that the hierarchical architecture is capable of recognizing different tactical patterns and variations in these patterns. Remaining problems are discussed and ideas concerning further improvements of classification are indicated. 相似文献

Previous findings concerning the relation of risk aversion and cooperation in repeated prisoner's dilemma games have been inconclusive. We hypothesized that this was due to an interaction between personality and environment. Specifically, we argued that in cooperation-friendly environments--given certain beliefs--defection is more risky than cooperation. The main reason for this is that, in such a situation, defection potentially yields outcomes of higher variance (and vice versa, for cooperation-unfriendly environments). In line with this hypothesis, we showed, in two experiments and a reanalysis of a study by Fudenberg, Rand, and Dreber (American Economic Review, in press), that the degree of cooperation increases with dispositional risk aversion in cooperation-friendly environments, but not in cooperation-unfriendly environments. We also found similar person-situation interactions for neuroticism and extraversion. 相似文献

In two experimental studies we found that participants who recalled a highly traumatic autobiographical event (trauma recall) compared with a lesser traumatic event (stress recall) reported having increasingly grown (posttraumatic growth, PTG). Moreover, participants who recalled a traumatic (vs. stressful) event perceived more death-related thoughts (Study 1) and reported coping with this event in a more emotion-focused and in a less problem-focused way (Study 2). Mediation analyzes revealed that the effect of trauma versus stress recall on PTG was mediated by emphasizing the positive, a subscale of emotion-focused coping. These results imply that growth resulting from traumatic events can be traced back to an illusion. No evidence was found that real PTG took place or that the effects shown resulted from death-related thoughts (terror management theory). 相似文献

And Lead Us (Not) into Persuasion…? Persuasive Technology and the Ethics of Communication 总被引:1,自引:0,他引:1
Spahn A 《Science and engineering ethics》2012,18(4):633-650
The paper develops ethical guidelines for the development and usage of persuasive technologies (PT) that can be derived from applying discourse ethics to this type of technologies. The application of discourse ethics is of particular interest for PT, since ??persuasion?? refers to an act of communication that might be interpreted as holding the middle between ??manipulation?? and ??convincing??. One can distinguish two elements of discourse ethics that prove fruitful when applied to PT: the analysis of the inherent normativity of acts of communication (??speech acts??) and the Habermasian distinction between ??communicative?? and ??strategic rationality?? and their broader societal interpretation. This essay investigates what consequences can be drawn if one applies these two elements of discourse ethics to PT. 相似文献

Avoidance behaviour is a crucial component of fear and is importantly involved in the maintenance of anxiety disorders. Presumably, fear conditioning leads to avoidance of the feared object or context. A virtual reality contextual fear conditioning paradigm was used to investigate the association between explicit conditioning effects and subsequent avoidance behaviour. Mild electric shocks were administered in one context (anxiety context), but never in a second context (safety context). Subsequent avoidance behaviour was assessed by asking participants to choose two out of three contexts (a neutral context was added) to visit again. Participants avoided the anxiety context, but did not prefer the safety over the neutral context. Participants with substantial conditioning effects, as reflected in differential valence, arousal and anxiety ratings, avoided the anxiety context but not the safety context. In sum, we demonstrated an association between context conditioning effects on an explicit level and later avoidance behaviour. 相似文献

This person‐centred study investigated the longitudinal patterns of vocational identity development in relation to personality, the development of well‐being, gender, nationality and the attended school track among two cohorts of Swiss adolescents in 8th or 9th grade (N = 269) and in 11th or 12th grade (N = 230). The results confirmed the existence of four identity statuses, namely, achievement, foreclosure, moratorium and diffusion. Forty‐two per cent of students showed progressive patterns of identity development, while 37% remained in their identity status over time. Students with different statuses and status change patterns differed significantly in their personality traits. Higher neuroticism related to the emergence of identity exploration over time, while conscientiousness related to maintaining or achieving a sense of identity commitment in terms of achievement or foreclosure. Controlling for the effects of socio‐demographics and personality traits, students who reached or maintained a state characterized by identity clarity and commitment showed a relative increase in life satisfaction, while those entering a state of identity crisis or exploration showed a decrease in life satisfaction.

While psychotherapy has proven its efficacy and effectiveness in the treatment of personality disorders (PD) there is a lack of studies on treatment failure, i.e. non-response or deterioration of psychopathology. In a naturalistic approach the failed treatment of1,239 inpatients with PD was studied by means of direct and indirect assessment of change from patient and therapist perspectives. For indirect assessment the global severity index of the symptom checklist SCL-90-R (self-report by patients) and the impairment severity score (judgement by therapists) were used. Depending on the method between 11% and 31% of inpatients did not show any relevant improvement in symptoms but concordance between the methods was poor (Cohen’s kappa between 0.10 and 0.30). Patients with treatment failure did not differ from those with successful treatment with respect to sociodemographic and clinical features. The findings are discussed with respect to methodological limitations but also reflect possible clinical and therapeutic implications as well as future research approaches. 相似文献

Background
Poor outcome of psychotherapeutic treatment has not yet been sufficiently investigated. It is assumed that approximately 25–30% of patients are treatment non-responders and about 5–10% suffer deterioration.Study design and methods
The therapeutic success of a total of 2,323 consecutively admitted inpatients with a depressive episode (F32.0-2, F33.0-2) was evaluated by using different strategies based on self ratings at admission and at discharge, i.e. the Beck depression inventory II (BDI-II) and the brief symptom inventory (BSI). In intention to treat (ITT) and completer analyses various measures of therapy success were compared (e.g. statistical significance, effect sizes and clinical significance).Results
Effect sizes were 1.59 (BDI-II) and 0.86 (BSI) for the ITT sample and 1.64 and 0.89 for the completer sample. Analyses using criteria of clinical significance resulted in response rates of 75.5% (BDI-II) and of 68.7% (BSI) for completer analyses and remission rates of 62.2% (BDI-II) and of 40.8% (BSI). Non-Response rates, also including minor responders, varied between 23.4% (BDI-II) and 27.4% (BSI). Deterioration was observed in only 1% (BDI-II) and 3.9% (BSI) of the patients.Discussion
The results demonstrate that about two thirds of depressive patients show clinically significant improvements within a multimodal, primarily psychotherapeutic inpatient setting, whereas the rates of deterioration are lower than expected. The aim for the future should be to identify poor or minor response as early as possible in order to optimize treatment. 相似文献320.

Sharing a public language facilitates particularly efficient forms of joint perception and action by giving interlocutors refined tools for directing attention and aligning conceptual models and action. We hypothesized that interlocutors who flexibly align their linguistic practices and converge on a shared language will improve their cooperative performance on joint tasks. To test this prediction, we employed a novel experimental design, in which pairs of participants cooperated linguistically to solve a perceptual task. We found that dyad members generally showed a high propensity to adapt to each other's linguistic practices. However, although general linguistic alignment did not have a positive effect on performance, the alignment of particular task-relevant vocabularies strongly correlated with collective performance. In other words, the more dyad members selectively aligned linguistic tools fit for the task, the better they performed. Our work thus uncovers the interplay between social dynamics and sensitivity to task affordances in successful cooperation. 相似文献
