In two experiments, each including a simple reaction time (RT) task, a localization task, and a passive oddball paradigm,
the physical similarity between two dichotically presented auditory stimuli was manipulated. In both experiments, a redundant
signals effect (RSE), high localization performance, and a reliable mismatch negativity (MMN) was observed for largely differing
stimuli, suggesting that these are coded separately in auditory memory. In contrast, no RSE and a localization rate close
to chance level (experiment 1) or at chance (experiment 2) were observed for stimuli differing to a lesser degree. Crucially, for such stimuli a small (experiment 1) or no (experiment 2) MMN were observed. These MMN results indicate that such stimuli tend to fuse into a single percept and that this fusion
occurs rather early within information processing. 相似文献

We examined the effects of positive and negative experiences with the partner (absorption in joint activities and conflict with the partner) during the weekend on affective states at the beginning of the following work week and tested whether recovery experiences (psychological detachment, relaxation, and mastery experiences) mediated these effects. In total, 269 university faculty members completed online surveys before and after the weekend. Hierarchical regression analyses revealed that absorption in joint activities with the partner predicted recovery experiences during the weekend and increased positive affective states (vigor, joviality, serenity) at the beginning of the following work week. Relaxation mediated the effects of absorption in joint activities on positive affective states. Conflict with the partner increased negative affective states (negative activation, fatigue), but was unrelated to recovery experiences. Our findings emphasize the importance of experiences with the partner for employees' recovery and show that the social environment of employees matters for their recovery. 相似文献

Background
So far only few studies are available which have evaluated the effectiveness of psychoeducation for individuals at risk of psychosis in the early initial prodromal state (EIPS) whereas the benefit of psychoeducation in psychotic patients has been repeatedly confirmed. Thus the aim of this study was to investigate the effect of psychoeducation in individuals with increased risk of psychosis in the EIPS.Method
A total of 128 help-seeking outpatients in the EIPS participated in a randomized controlled multicentre trial of 12 months of either psychoeducation as part of an integrated psychological intervention (IPI) or supportive counseling (SC). The time to transition to psychosis at 12-month and 24-month follow-up as well as the social adjustment at baseline, time of transition or post-treatment by means of the social adjustment scale (SAS?II) were assessed.Results
The IPI was superior to SC in preventing progression to psychosis at 12-month (3.2% versus 16.9%, p?=0.008) and 24-month follow-up (6.3% versus 20.0%, p?=0.019). Both treatments resulted in significant pre-post improvements in SAS?II with no significant differences between the two groups.Conclusions
Psychoeducation as part of an integrated intervention is effective for preventing the onset of psychosis over a 24-month time period in people in an EIPS. Moreover patients at risk of developing first episode psychosis seem to benefit from a specific psychoeducational intervention in the context of other treatments as well as from SC. 相似文献135.

When participants are asked to respond in the same way to stimuli from different sources (e.g., auditory and visual), responses
are often observed to be substantially faster when both stimuli are presented simultaneously (redundancy gain). Different
models account for this effect, the two most important being race models and coactivation models. Redundancy gains consistent
with the race model have an upper limit, however, which is given by the well-known race model inequality (Miller, 1982). A number of statistical tests have been proposed for testing the race model inequality in single participants and groups
of participants. All of these tests use the race model as the null hypothesis, and rejection of the null hypothesis is considered
evidence in favor of coactivation. We introduce a statistical test in which the race model prediction is the alternative hypothesis.
This test controls the Type I error if a theory predicts that the race model prediction holds in a given experimental condition. 相似文献

The significance of the complicated numbering of the propositions in the Tractatus has occasioned much speculation. Wittgenstein's own explanation has, following Stenius, been generally regarded as misleading. But an examination of the Prototractatus reveals that the numbering system was for Wittgenstein principally an aid in the composition of his work. It allowed him to mark out certain propositions which required further work or supplementation, without disturbing the basic structure of the treatise. But the reworking of the Prototractatus to form the Tractatus considerably changed the original order in which the ideas were connected, and thus made it more difficult to understand the Tractatus. Several specific examples make it clear that it is essential to look back at the context of the Prototractatus in order to achieve a correct interpretation of many of the propositions in the Tractatus. 相似文献

Selective attention has durable consequences for behavior and neural activation. Negative priming (NP) effects are assumed to reflect a critical inhibitory component of selective attention. The performance of adolescents with Attention Deficit/Hyperactivity Disorder (ADHD) was assessed across two conceptually based NP tasks within a selective attention procedure. Comorbidity (non-comorbid ADHD vs. comorbid ADHD) and subtype (ADHD combined vs. ADHD inattentive) were considered key issues. Results found NP effects to differ as a function of comorbidity but not subtype. Findings are discussed in light of functional neuroimaging evidence for neuronal enhancement for unattended stimuli relative to attended stimuli that strongly complements an inhibitory-based explanation for NP. Implications for the ‘AD’ in ADHD and contemporary process models of the disorder are considered. 相似文献

In this article we suggest that independent vs. interdependent aspects of the self yield different manifestations of psychological reactance and that this is especially relevant in a cross-cultural context. In Studies 1, 2, and 4 we showed that people from collectivistic cultural backgrounds (individuals holding more interdependent attitudes and values) were less sensitive to a threat to their individual freedom than people from individualistic cultural backgrounds (individuals holding more independent attitudes and values), but more sensitive if their collective freedom was threatened. In Study 3 we activated independent vs. interdependent attitudes and values utilizing a cognitive priming method and yielded similar results as the other studies hinting at the important causal role of self-related aspects in understanding reactance in a cross-cultural context. 相似文献
