Regarding awareness as a consistent concept has contributed to the controversy about implicit learning. The present study emphasized the importance of distinguishing aspects of awareness in order to determine whether learning is implicit. By decomposing awareness into awareness of contingencies, of the procedure being a learning task, and of the reinforcing stimuli, it was demonstrated that implicit operant learning modulated pain sensitivity. All of these aspects of awareness were demonstrated to not be necessary for learning. Additionally, discrimination of contingencies was not necessary on different levels of processing as demonstrated by a verbal and a behavioral method. It was demonstrated that explicit cognitive processes about one's own behavior, impaired learning, even though these cognitions were not immediately related to the learning process. The results of this study are of special interest in the context of pain, since implicit operant learning can explain the gradual development of hypersensitivity in chronic pain.  相似文献

People with cognitive functional limitations (CFLs) have rarely been the focus of research dealing with road users and their needs. The aim of the present study was to describe how people with CFL post-stroke manage in their use of buses in the framework of their outdoor mobility, and to find out what difficulties, but also what opportunities, they experienced when moving from origin to destination using buses in public transport. Semi-structured interviews combined with participant observations during bus trips with eight persons were performed. Several barriers that have the potential to restrict autonomous outdoor mobility were identified. These barriers were not only represented by well-known infrastructure problems (high pavement curbs, etc.) or ergonomic shortcomings in the buses but, even more so, by specific issues relevant for persons with CFL, e.g. having to cross a road on their way to the bus stop, which poses problems of interaction with fast-moving car traffic. Obtaining all the necessary information prior to and during the trip is difficult and produces insecurity. Often, communication with the bus drivers, not least in connection with the search for information, causes extra stress. Lack of self-confidence and feelings of inferiority add to these problems. Measures to control vehicle speeds, to optimise the communication style of bus drivers with their customers, and to improve customers’ access to information are recommended. Training measures to reassure persons with CFL in connection with their use of the public space are suggested.  相似文献

A social networking Web site, Facebook, was used to deliver long-term sport psychology consultation services to student-athletes (i.e., soccer players) in 30- to 60-min weekly sessions. Additional short-term team building, group cohesion, communication, anger management, injury rehabilitation, mental toughness, commitment, and leadership workshops were provided. Cohesion and overall relationships between both the student-athletes and the sport psychology consultants benefited from this process. Social networking Web sites offer a practical way of providing sport psychology consulting services that does not require use of major resources.

Experienced Qigong meditators who regularly perform the exercises "Thinking of Nothing" and "Qigong" were studied with multichannel EEG source imaging during their meditations. The intracerebral localization of brain electric activity during the two meditation conditions was compared using sLORETA functional EEG tomography. Differences between conditions were assessed using t statistics (corrected for multiple testing) on the normalized and log-transformed current density values of the sLORETA images. In the EEG alpha-2 frequency, 125 voxels differed significantly; all were more active during "Qigong" than "Thinking of Nothing," forming a single cluster in parietal Brodmann areas 5, 7, 31, and 40, all in the right hemisphere. In the EEG beta-1 frequency, 37 voxels differed significantly; all were more active during "Thinking of Nothing" than "Qigong," forming a single cluster in prefrontal Brodmann areas 6, 8, and 9, all in the left hemisphere. Compared to combined initial-final no-task resting, "Qigong" showed activation in posterior areas whereas "Thinking of Nothing" showed activation in anterior areas. The stronger activity of posterior (right) parietal areas during "Qigong" and anterior (left) prefrontal areas during "Thinking of Nothing" may reflect a predominance of self-reference, attention and input-centered processing in the "Qigong" meditation, and of control-centered processing in the "Thinking of Nothing" meditation.  相似文献

Decision-making policies are subject to modulation by changing motivational states. However, so far, little is known about the neurochemical mechanisms that bridge motivational states with decision making. Here we examined whether dopamine (DA) in the nucleus accumbens core (AcbC) modulates the effects of motivational states on effort-based decision making. Using a cost–benefit T-maze task in rats, we examined the effects of AcbC DA depletions on effort-based decision making, in particular on the sensitivity of effort-based decision making to a shift from a hungry to a sated state. The results demonstrated that, relative to sham controls, rats with AcbC DA depletion in a hungry as well as in a sated state had a reduced preference for effortful but large-reward action. This finding provides further support for the notion that AcbC DA regulates how much effort to invest for rewards. Importantly, our results further revealed that effort-based decision making in lesioned rats, as in sham controls, was still sensitive to a shift from a hungry to a sated state; that is, their preferences for effortful large-reward actions became lower after a shift from a restricted to a free-feeding regimen. These finding indicate that AcbC DA is not necessarily involved in mediating the effects of a shift in motivational state on decision-making policies.  相似文献

In this study, 216 risk assessments conducted by law enforcement officers in a suburb of Stockholm using the Brief Spousal Assault Form for the Evaluation of Risk (B-SAFER) were followed up and correlated to both recidivism and type of protective actions implemented by the police. The results showed high recidivism rates across all risk categories, except in the highest risk group, where the recidivism rate was significantly lower. This finding suggests a poor, and even negative, predictive power of the police risk assessments: the higher the police-assessed risk, the lower the recidivism rate. However, it was clear that the police did very little, or nothing, in cases not assessed as high risk. All resources appear to have been directed to the high-risk cases, which seems to have had a preventive effect. Our results point to the importance of studying the nature and extent of protective actions taken in response to risk assessment, before drawing conclusions about the predictive validity of risk assessment instruments.

Family systems play a crucial, albeit complex, role in pediatric chronic illness. Unfortunately, very few psychosocial interventions are available to help these stressed families navigate the developmental steps of chronic illness. A new intervention (MEND) addresses the needs of these families and applies to a broad range of chronic illnesses. This article presents this family systems intervention as well as includes preliminary program evaluation data on 22 families that graduated from the program. Results show consistently strong effects across an array of psychosocial measures. Conclusions from this preliminary study suggest that families entering MEND present with high levels of stress due to the child's chronic illness, but after MEND, the level of stress and other functioning measures are comparable to those seen in healthy families, suggesting that the program offers a significant benefit to families with pediatric chronic illness.  相似文献

Recent considerations around DSM–5 criteria of personality disorders (PDs) demand new concepts of assessing levels of personality functioning. Of special interest are multiperspective approaches accounting for clinicians’ as well as patients’ points of view. The study investigates observer-rated and self-assessed levels of personality functioning measured by the level of structural integration as defined by the Operationalized Psychodynamic Diagnosis System (OPD). Both perspectives were positively related. The combination of both measures was most efficient in discriminating among 3 diagnostic groups of varying degrees of personality dysfunction. Future studies should take into account expert ratings as well as self-report data.  相似文献

Background and Objectives: A number of sources suggest changes in anxiety across the transition to parenthood may be experienced by parents in different ways, yet no studies have examined whether new parents experience changes in anxiety in distinct subgroups. Design: We conducted a longitudinal study of 208 first-time parents (104 couples) from a low-risk population. Parents were interviewed from the third trimester of pregnancy to nine-months postpartum. Methods: The current study utilized latent class growth analysis to explore subgroups of change in symptoms of anxiety. Based on stress and coping theory, we also examined a number of personal and social prenatal predictors of subgroup membership. Results: We identified two distinct change trajectories: (1) moderate and stable and (2) low and declining. We also found prenatal depression, expected parenting efficacy, and relationship satisfaction were significantly associated with subgroup membership. Conclusions: Our results suggest a majority of new parents adjust well to parenthood in terms of anxiety, while a smaller subgroup of parents experience continually higher levels of anxiety months after the baby is born.  相似文献

The extrastriate body area (EBA) and the fusiform body area (FBA) are selectively activated by viewing human bodies. However, the role of these functionally defined brain areas in self-other discrimination is still unresolved. Thirty-one females were presented with 16 pictures of their own body and another body in a bikini and with scrambled images while fMRI was performed. Moreover, standardized stimulus material was used in order to localize the EBA and FBA. Region-of-interest analysis showed an enhanced BOLD response to the self-images relative to the non-self-images in the right EBA and FBA. The right EBA and FBA are activated differently by viewing oneself and others and might thus play a role in visual self-other discrimination.  相似文献
