The present article discusses the concept of synderesis in the late medieval universities of Erfurt and Leipzig and the later developments in Wittenberg. The comparison between Bartholomaeus Arnoldi of Usingen in Erfurt and Johannes Peyligk in Leipzig shows that school traditions played an important role in the exposition of synderesis by the late medieval scholastic natural philosophers. However, Jodocus Trutfetter's example warns against overemphasizing the importance of the school traditions and reminds us of the manifold history of medieval discussions on synderesis, which were more or less familiar to many authors of this period. Finally, the diverse references to synderesis in the texts of Martin Luther, Johannes Bernhardi of Feldkirch and Philip Melanchthon reveal no uniform relationship with late medieval discussions but rather indicate various ways of adopting scholastic ideas and transforming them in the context of humanist and reformation thinking.  相似文献

Peri-traumatic information processing is thought to affect the development of intrusive trauma memories. This study aimed to replicate and improve the study by Holmes, Brewin, and Hennessy (2004, Exp. 3) on the role of peri-traumatic verbal processing in analogue traumatic intrusion development. Participants viewed an aversive film under one of three conditions: counting backwards in 3s (“verbal interference”), verbalising emotions and thoughts (“verbal enhancement”), or without an extra task. A dual-process account of PTSD would predict that verbal interference would increase intrusion frequency compared to no task, whereas verbal enhancement would lead to a decrease. In contrast, mainstream memory theory predicts a decrease in intrusion frequency from any concurrent task that diverts attention away from the trauma film. The main finding was that the verbal interference task led to a decrease in intrusive memories of the film compared to the other two conditions. This finding does not support a dual-process account of PTSD, but is in line with general theories of memory and attention.  相似文献

The authors examined how the effectiveness of feedback for the learning of complex motor skills is affected by the focus of attention it induces. The feedback referred specifically either to body movements (internal focus) or to movement effects (external focus). In Experiment 1, groups of novices and advanced volleyball players (N = 48) practiced “tennis” serves under internal-focus or external-focus feedback conditions in a 2 (expertise) × 2 (feedback type) design. Type of feedback did not differentially affect movement quality, but external-focus feedback resulted in greater accuracy of the serves than internal-focus feedback during both practice and retention, independent of the level of expertise. In Experiment 2, the effects of relative feedback frequency as a function of attentional focus were examined. A 2 (feedback frequency: 100% vs. 33%) × 2 (feedback type) design was used. Experienced soccer players (N = 52) were required to shoot lofted passes at a target. External-focus feedback resulted in greater accuracy than internal-focus feedback did. In addition, reduced feedback frequency was beneficial under internal-focus feedback conditions, whereas 100% and 33% feedback were equally effective under external-focus conditions. The results demonstrate the effectiveness of effect-related, as opposed to movement-related, feedback and also suggest that there is a need to revise current views regarding the role of feedback for motor learning.  相似文献

Aimed flexion movements of the arm of different amplitude and duration were studied. Velocity and acceleration traces of movements with equal duration but different amplitude were equal, apart from a scaling factor (ratio between movement amplitudes). After appropriate scaling, EMG activity of the first agonist burst for these movements superimposed. This was not true for EMG activity in the antagonist muscle.

For movements with equal amplitude, but different duration, the time to peak acceleration was constant for all MT’s. Except for this fact, traces of acceleration, velocity, and agonist activity following the time of peak acceleration were about equal after appropriate scaling in time and amplitude. The integral of EMG activity in the first agonist burst increased linearly with peak velocity. For the antagonist burst, the integrated EMG activity increased more than proportionally.

During movements made as fast as possible, subjects used a different strategy by varying the duration of the accelerating phase for movements of different amplitude. Movement amplitude was achieved by adjusting the duration of the agonist burst and the onset time for the antagonist muscle. Amplitude of the antagonist burst was constant within a narrow range for movements of different amplitude.

These results did not change when the inertial mass was doubled by loading the arm with an additional mass.  相似文献

This study investigated a possible mechanism behind employment discrimination. Participants completed a recruitment task where emphasis on cohesion (employees should “fit in”) versus fairness (everybody should be treated equally) was manipulated by describing the norms of a fictitious company differently. There was a comparatively stronger preference in the cohesion condition for traits and interview questions related to social competence (e.g., friendliness, gregariousness, empathy). Furthermore, participants in the cohesion condition primarily pictured socially competent employees, whereas those in the fairness condition primarily pictured employees possessing productivity-related characteristics (e.g., education, experience, and talent). The norm effect was moderated by participants’ awareness of the applicants’ ethnicity. When expecting applicants with foreign backgrounds, participants in the cohesion condition showed increased preference for selection methods related to social competence. Implications for recruitment practices are discussed.  相似文献

This research is an investigation of the hedonic intensities of elation and disappointment following the outcomes of risky gambles using two principles: disappointment aversion and the principle of limited emotion processing. Disappointment aversion implies a stronger impact of disappointment compared with elation; the principle of limited emotion processing predicts a smaller impact of elation if it occurs with a real gain, and a smaller impact of disappointment if it occurs with a real loss. Both principles support each other in the gain domain but operate against each other in the loss domain. It was predicted that disappointment would outweigh elation in the gain domain. For the loss domain, this question was left open to empirical scrutiny. Participants were provided with hypothetical gambles and were required to imagine having won, not won, lost, or not lost, money. Results supported the prediction for the gain domain; mixed results emerged for the loss domain. The model adds to the understanding of the cognitive and emotional processes following the outcomes of risky events.  相似文献

The level of motivation (i.e. incentive power) is thought to be one of the most important factors affecting performance and learning in various tasks. We investigated whether reward quality has an effect on the performance of family dogs in a two-way object choice test in which they can find the hidden food by relying on distal momentary human pointing cues. In three experiments we varied (1) the type of food reward according to the subjects’ own preference; (2) the quality of the reward offered at the same time in the indicated and not-indicated locations; and (3) the order of the high or low quality rewards in consecutive sessions. In Experiment 1, we first tested whether dogs prefer one kind of reward over another. Then one group was tested with the ‘preferred’ food as reward in the indicated bowl, while dogs in the other group received the ‘non-preferred’ food as reward. We did not find any difference between the performance and choice latencies of the two groups. In Experiment 2 for the first group, the indicated bowl contained a piece of carrot and the not-indicated bowl was empty. In the second group the indicated bowl contained carrot, but the not-indicated bowl contained sausage. According to a preliminary preference test, most dogs prefer sausage over carrot invariably. After 20 trials, the two groups performed surprisingly similarly. There was no difference found between groups in the number of correct choices, incorrect choices and non-choices. However, the comparison between the first and last five trials revealed that subjects who found sausage when they chose the not-indicated bowl (did not follow the pointing) chose the non-indicated bowl significantly more often toward the end of their test session. In Experiment 3, each dog received two sessions with 12 pointing trials in each. For the first session, one group was rewarded with sausage and the other with carrot upon choosing the indicated bowl. In the second session, the indicated bowl contained dry dog food for both groups. We found that correct choices and response latencies did not change over two sessions in the ‘sausage’ group. In the ‘carrot’ group, the dogs chose faster in the second session, but their performance did not improve; in fact, they chose the not-indicated bowl more often than the indicated bowl. As a conclusion, we can say that reward quality had some effect on dogs’ choice behavior in these experiments. The drop in their performance was not drastic, taking into account the general refusal to eat one of the ‘rewards’ (carrot) during the preference tests and also during the test trials. It seems that incentive contrast may play a relatively minor role in dog-human social interactions. Appropriate reward quality can be very important in asocial problem solving tasks, but, when interacting with humans, following human signals may override the effect of changed incentive power.  相似文献

The goal of this study was to explore how crafts help women, who do crafting as a leisure activity, cope with stress. This qualitative study is based on the narratives of 15 textile craft makers aged 27–57 who were reporting stress in work and non-work settings. The participants reported that their crafting varied depending on the specific life circumstances they encountered. The analysis revealed that crafts provided recreation, satisfaction, optimism, positive relationships, and support as well as helped participants to cope with negative feelings. Crafts served as a leisure-coping resource and a leisure-based coping strategy.  相似文献

In many respects the status of psychotherapy in public health-care systems is similar to that of alternative medicine. The roots of training are outside universities. Legitimation and public funding have been non-existent or insufficient as compared with other fields of health care. Also a great deal of mysticism is attached to both. It is therefore relevant to study the role of psychotherapy from the frame of reference given by research into alternative health care.

Formal health care is characterised by (1) legalised status, (2) access to public funding and (3) integration in the formal medical curriculum. On the other hand there are several treatment philosophies which remain as outsiders from the point of view of formal health care. Informal health care approaches are characterised by (1) lack of legalised status, (2) no access to public funding and (3) no integration in the medical curriculum. Alternative medicine is a term usually attached to forms of informal health care like acupuncture, Spa-culture etc.

Psychotherapy in the public health sector lies somewhere between formal and informal health care. While it has no legalised status, anyone may call himself ‘psychotherapist’. Its definition remains obscure and its public accountability poor.

In this paper I have tried to show how one country — Finland — has tried to grapple with this problem as it attempted to set up psychotherapy services whose quality could be properly monitored — ‘Quality Assurance’ — allowing for public accountability. Now that psychotherapy is well established as a valuable treatment in the field of mental health it is possible to consider future expansion as a cost-effective way to improve the general mental health of the country.  相似文献
