The effects of two kinds of meditation (open presence and focused) on the facial and physiological aspects of the defensive response to an aversive startle stimulus were studied in a Buddhist monk with approximately 40 years of meditation experience. The participant was exposed to a 115-db, 100-ms acoustic startle stimulus under the 2 meditation conditions, a distraction condition (to control for cognitive and attentional load) and an unanticipated condition (startle presented without warning or instruction). A completely counterbalanced 24-trial, single-subject design was used, with each condition repeated 6 times. Most aspects of the participant's responses in the unanticipated condition did not differ from those of a comparison group of 12 age-matched male controls. Both kinds of meditation produced physiological and facial responses to the startle that were smaller than in the distraction condition. Within meditation conditions, open presence meditation produced smaller physiological and facial responses than focused meditation. These results from a single highly expert meditator indicate that these 2 kinds of meditation can differentially alter the magnitude of a primitive defensive response.  相似文献

The current study provides naturalistic data documenting the pathways-to-care to vocational services for 155 veterans who were receiving some form of mental health care from the Veterans Health Administration and had a vocational need but were not currently enrolled in vocational services. Of the participants, 94.2% had recognized their vocational need, 80.6% reported that they or someone else had sought help to alleviate the need, and 77.4% had previously received some form of vocational services. The median length of the participants' vocational need was more than 4.2 years. Delays associated with recognition, help-seeking, and treatment entry all contributed to the overall delay in entering appropriate care. Filtering factors associated with quicker recognition, seeking help, and receiving services included diagnosis, level of disability, type of vocational need, and support from primary providers, family, and friends. The results provide information for designing interventions to improve service entry by adults with mental health problems and vocational needs.  相似文献

Research on spatial cognition has focused on how animals encode the horizontal component of space. However, most animals travel vertically within their environments, particularly those that fly or swim. Pelagic fish move with six degrees of freedom and must integrate these components to navigate accurately--how do they do this? Using an assay based on associative learning of the vertical and horizontal components of space within a rotating Y-maze, we found that fish (Astyanax fasciatus) learned and remembered information from both horizontal and vertical axes when they were presented either separately or as an integrated three-dimensional unit. When information from the two components conflicted, the fish used the previously learned vertical information in preference to the horizontal. This not only demonstrates that the horizontal and vertical components are stored separately in the fishes' representation of space (simplifying the problem of 3D navigation), but also suggests that the vertical axis contains particularly salient spatial cues--presumably including hydrostatic pressure. To explore this latter possibility, we developed a physical theoretical model that shows how fish could determine their absolute depth using pressure. We next considered full volumetric spatial cognition. Astyanax were trained to swim towards a reward in a Y-maze that could be rotated, before the arms were removed during probe trials. The subjects were tracked in three dimensions as they swam freely through the surrounding cubic tank. The results revealed that fish are able to accurately encode metric information in a volume, and that the error accrued in the horizontal and vertical axes whilst swimming in probe trials was similar. Together, these experiments demonstrate that unlike in surface-bound rats, the vertical component of the representation of space is vitally important to fishes. We hypothesise that the representation of space in the brain of vertebrates could ultimately be shaped by the number of the degrees of freedom of movement that binds the navigating animal.  相似文献

Although Freud had aspirations of a university structure for psychoanalytic education the sociopolitical structure of the Austro-Hungarian empire precluded this, and psychoanalysis developed by default in the central European heartland within a part-time, private-practice educational structure. With its rapid spread in the post-World-War-II United States, and its ready penetration of American academic psychiatry, a counter educational structure arose in some quarters: the department-of-psychiatry-affiliated institute within the medical school. This article outlines beyond these other, more ambitious, academic vistas (the David Shakow model, the Anna Freud model, the Menninger Foundation, Emory University (USA), AP de BA (Argentina)); conceptions even closer to the ideal (idealized) goal of full-time placement within the university, with strong links to medicine, to the behavioral sciences and to the humanities. The putative advantages of such a structure are presented.  相似文献

Epidemiological studies of categorical mental disorders consistently report that gender differences exist in many disorder prevalence rates and that disorders are often comorbid. Can a dimensional multivariate liability model be developed to clarify how gender impacts diverse, comorbid mental disorders? We pursued this possibility in the National Epidemiologic Survey on Alcohol and Related Conditions (NESARC; N = 43,093). Gender differences in prevalence were systematic such that women showed higher rates of mood and anxiety disorders, and men showed higher rates of antisocial personality and substance use disorders. We next investigated patterns of disorder comorbidity and found that a dimensional internalizing-externalizing liability model fit the data well, where internalizing is characterized by mood and anxiety disorders, and externalizing is characterized by antisocial personality and substance use disorders. This model was gender invariant, indicating that observed gender differences in prevalence rates originate from women and men's different average standings on latent internalizing and externalizing liability dimensions. As hypothesized, women showed a higher mean level of internalizing, while men showed a higher mean level of externalizing. We discuss implications of these findings for understanding gender differences in psychopathology and for classification and intervention.  相似文献

Although modern mental health systems increasingly require evidence-based practice (EBP), clinicians continue to object to restrictions on their professional independence, which they may perceive as counterproductive, divisive and even demeaning. In the face of such deep-seated objections, do we really need to strive for an evidence-based approach to supervision? We believe so, and begin our argument by noting a colourful illustration of the problems that can exist in the absence of EBP, those of poor training, therapist drift and weak professional regulation. Next, we present EBP as a mechanism to reduce such unacceptable variability in the way that treatments are delivered. We then apply the lessons from this divisive situation to the practice of clinical supervision, outlining a rationale for an inclusive, synergistic way forward. A number of fundamental psychological motives for this integration are noted, including supervisor training that is informed by practice-based research, corrective feedback on supervision, and a supportive professional system. Illustrative examples are provided in each of these areas. It is concluded that the traditional gulf between research and practice can and should be bridged in relation to supervision.  相似文献

Familial processes are gaining an increased amount of attention in cognitive behavioural therapy. Their role in initiating, maintaining, and exacerbating distress in children and adolescents has clear clinical implications. Therefore, including parents in their children’s therapy sessions as coaches, collaborators, and co-patients is becoming commonplace in CBT approaches to internalizing disorders such as anxiety. This article describes a case of a 13?year old female who presented with features of Generalized Anxiety Disorder and Separation Anxiety whose course of treatment involved her mother as a coach, collaborator and co-patient. A case formulation is offered and the specific examples of CBT practices used in each session are detailed. Ways of evaluating treatment outcome are also discussed.  相似文献

Linguistic labels affect inductive generalization; however, the mechanism underlying these effects remains unclear. According to one similarity-based model, SINC (similarity, induction, naming, and categorization), early in development labels are features of objects contributing to the overall similarity of compared entities, with early induction being similarity based. If this is the case, then not only identical but also phonologically similar labels may contribute to the overall similarity and thus to induction. These predictions were tested in a series of experiments with 5-year-olds and adults. In Experiments 1-5 participants performed a label extension task, whereas in Experiment 6 they performed a feature induction task. Results indicate that phonological similarity contributes to early induction and support the notion that for young children labels are features of objects.  相似文献

State mood has been proposed as a facilitator of creative behavior. Whereas positive mood compared to neutral mood generally facilitates creative performance, mood effects are weaker and less consistent when positive mood is compared to negative mood. These inconsistent results may be due to focusing only on mood valence, while neglecting or confounding mood activation. The current study is based on the dual-pathway model, which describes separate roles for mood valence and mood activation in facilitating creativity. We used experience sampling methodology to investigate the concurrent and lagged effects of mood valence and activation on creative process engagement (CPE) within-person over time among individuals working on a long-term project requiring creativity. We also investigated the moderating effects of individual differences in goal orientation and supervisory support on within-person mood-creativity relationships. As expected, we found that activating positive and activating negative moods were positively associated with concurrent CPE, whereas deactivating moods of both valences were negatively related to CPE. Activating negative mood had a significant lagged effect on CPE, whereas activating positive mood did not. We also found that activating positive mood was more strongly related to concurrent CPE among individuals with high rather than low learning goal orientation. Further, activating positive mood interacted with prove goal orientation and supervisory support for creativity, such that activating positive mood had the strongest association with CPE when both prove goal orientation and supervisory support were high.  相似文献

There is a common belief that wrinkles in the aging face reflect frequently experienced emotions and hence resemble these affective displays. This implies that the wrinkles and folds in elderly faces interfere with the perception of other emotions currently experienced by the elderly as well as with the inferences perceivers draw from these expressions. Whereas there is ample research on the impact of aging on emotion recognition, almost no research has focused on how emotions expressed by the elderly are perceived by others. The present research addresses this latter question. Young participants rated the emotion expressions and behavioral intentions of old and young faces displaying identical expressions. The findings suggest that emotions shown on older faces have reduced signal clarity and may consequently have less impact on inferences regarding behavioral intentions. Both effects can be expected to have negative consequences for rapport achieved in everyday interactions involving the elderly.  相似文献
