Sensitivity to prosodic cues might be used to constrain lexical search. Indeed, the prosodic organization of speech is such that words are invariably aligned with phrasal prosodic edges, providing a cue to segmentation. In this paper we devise an experimental paradigm that allows us to investigate the interaction between statistical and prosodic cues to extract words from a speech stream. We provide evidence that statistics over the syllables are computed independently of prosody. However, we also show that trisyllabic sequences with high transition probabilities that straddle two prosodic constituents appear not to be recognized. Taken together, our findings suggest that prosody acts as a filter, suppressing possible word-like sequences that span prosodic constituents. 相似文献

The accumulation of research findings now suggest a significant work stress problem, with implications for worker health, motivation and productivity, that warrants a concerted applied research effort at a local level and a strategy and policy response at a national level. Psychologists need to rethink prevailing paradigms that often separate their research and practice. We argue that a conducive production model that emphasizes action and knowledge, and reciprocal learning between academia, practitioners, and organizations may be the way forward for psychologists to respond effectively to the current work stress problems and other emergent organizational issues. Failure to do so may result in exacerbation of problems related to the psychological and social context of work, a slowed response to increased demands, and an ever decreasing practical utility of the profession. 相似文献

The present research investigated the role of two sources of psychological need satisfaction (inside and outside a passionate activity) as determinants of harmonious (HP) and obsessive (OP) passion. Four studies were carried out with different samples of young and middle‐aged adults (e.g., athletes, musicians; total N = 648). Different research designs (cross‐sectional, mixed, longitudinal) were also used. Results showed that only a rigid engagement in a passionate activity (OP) was predicted by low levels of need satisfaction outside the passionate activity (in an important life context or in life in general), whereas both OP and a more favorable and balanced type of passion, HP were positively predicted by need satisfaction inside the passionate activity. Further, OP led to negative outcomes, and HP predicted positive outcomes. These results suggest that OP may represent a form of compensatory striving for psychological need satisfaction. It appears important to consider two distinct sources of need satisfaction, inside and outside the passionate activity, when investigating determinants of optimal and less optimal forms of activity engagement. 相似文献

Mindfulness-based stress reduction (MBSR) has been reported to reduce anxiety in a broad range of clinical populations. However, its efficacy in alleviating core symptoms of specific anxiety disorders is not well established. We conducted a randomized trial to evaluate how well MBSR compared to a first-line psychological intervention for social anxiety disorder (SAD). Fifty-three patients with DSM-IV generalized SAD were randomized to an 8-week course of MBSR or 12 weekly sessions of cognitive-behavioral group therapy (CBGT). Although patients in both treatment groups improved, patients receiving CBGT had significantly lower scores on clinician- and patient-rated measures of social anxiety. Response and remission rates were also significantly greater with CBGT. Both interventions were comparable in improving mood, functionality and quality of life. The results confirm that CBGT is the treatment of choice of generalized SAD and suggest that MBSR may have some benefit in the treatment of generalized SAD. 相似文献

The study objective was to compare breast cancer screening practices, lifestyle behaviors and psychological distress among 640 women initiating BRCA1/2 testing to those among 9,498 similarly-aged women from the general population. Health behaviors and psychological distress were reported in a self-administered questionnaire at pre-test genetic counseling. Regression analyses indicate that high-risk women were more frequently performing breast cancer screening and, in the case of those previously diagnosed with cancer, were more likely to be non-smokers and physically active than women from general population. However, women initiating BRCA1/2 testing were significantly more distressed than controls. Globally, high-risk women seemed to be well informed about recommendations for women who are at high risk and to have access to screening adapted to their risk level. Given their significant psychological distress, providing minimal psychosocial support to all women undergoing BRCA1/2 testing at pre-test genetic counseling is relevant. 相似文献

This article aims to show how the alternating trainings have been treated by researchers using social psychology approaches. It identifies the theoretical models used, the main researches and some of their results. It comes to the idea that psychology appears as an essential discipline to understand the evolutions of the individuals in these work and training situations but it not sufficiently used. Then, some topics for future researches are designed. The alternating training appears as a very rich situation which allows to understand the individual as well as organizational transformations and the different levels of interrelations of the individual with his/her environment. 相似文献

In continuous vigilance tasks, the number of coincident panel responses to stimuli provides an index of stimulus detectability. To determine whether this number is due to chance, panel noise levels have been approximated by the maximum coincidence level obtained in stimulus-free conditions. This study proposes an alternative method by which to assess noise levels, derived from queuing system theory (QST). Instead of critical coincidence levels, QST modeling estimates the duration of coinciding responses in the absence of stimuli. The proposed method has the advantage over previous approaches that it yields more reliable noise estimates and allows for statistical testing. The method was applied in an olfactory detection experiment using 16 panelists in stimulus-present and stimulus-free conditions. We propose that QST may be used as an alternative to signal detection theory for analyzing data from continuous vigilance tasks. 相似文献
