To determine the effects of both corticosterone (B) and chronic stressors on acute ACTH responses to restraint, young male rats were exposed to streptozotocin-induced diabetes, cold (5-7 degreesC) or intracerebroventricular (icv) neuropeptide Y (NPY) for 5 d and then exposed to restraint within 2 h after lights on. Two groups of rats were studied: intact and adrenalectomized replaced with B pellets that maintained plasma B in the normal mean 24-h range of intact rats. In addition to ACTH and B responses to restraint on d 5, body weight, food intake, fat depots, glucose and other hormones were measured to determine the role of stress-induced elevations in B on energy balance. ACTH responses to restraint were normal in intact rats subjected to diabetes or cold. By contrast, there was no ACTH or B response to restraint in NPY-infused intact rats. All 3 groups of chronically stimulated adrenalectomized rats with clamped B had facilitated ACTH responses to restraint compared to their treatment controls. Overall food intake increased in all groups of stressed rats; however, augmented intake occurred only during the light in intact rats and equally in the light and dark in B-clamped rats. White adipose depot weights were decreased by both diabetes and cold and increased by NPY in intact rats; the decreases with cold and increases with NPY were both blunted and changes in fat stores were not significant in adrenalectomized, B-clamped rats. We conclude that: 1. diabetes- and cold-induced facilitation of restraint-induced afferent input to hypothalamic control of the hypothalamo-pituitary-adrenal (HPA) axis is opposed in intact rats by the elevated feedback signal of B secretion; 2. NPY does not induce facilitation of afferent stress pathways; 3. chronic stimulation of the HPA axis induces acute hyperresponsiveness of hypothalamic neurons to restraint provided that the afferent input of this acute stimulus is not prevented by B feedback; 4. stimulus-induced elevations in B secretion result in day-time feeding; 5. insensitivity of both caloric efficiency and white fat stores to chronic stress in adrenalectomized, B-clamped rats results from loss of normally variable B levels.  相似文献

A formative evaluation (consisting of two phases: a scoping literature review and a focus group with mental health professionals) was conducted to inform the design of a web-based intervention to prevent postpartum depression, in terms of its characteristics and content: the Be a Mom program. The results showed that the web-based intervention should be short-term, delivered postnatally, and grounded in cognitive-behavior therapy principles. Moreover, the intervention should include weekly sessions targeting basic contents: motherhood changes, reorganizations and emotional experience; cognitions, self-criticism, and self-compassion; parenting values, social support, and assertive communication skills; couple relationship, negotiation and conflict resolution skills; and postpartum depression signs and professional help-seeking. These results may improve the Be a Mom’s adequacy, implementation success, and effectiveness.  相似文献

Movement organization of cricket batters' actions was analyzed under three distinct experimental task constraints: a representative condition of a practice context in which the batters batted against a "live" bowler, a ball projection machine, and a near life-size video simulation of a bowler. Results showed that each distinct set of task constraints led to significant variations in the patterns of movement control. Removal of advanced information sources from a bowler's actions when the batters faced the ball projection machine caused significant delays in movement initiation, resulting in reduced peak bat swing velocities and a reduction in the quality of bat-ball contact, when compared with batting against a "live" bowler. When responding to a two-dimensional video simulation, batters were able to use information from the bowlers' action, enabling fidelity of initial behavioral responses consistent with the task of batting against a "live" bowler. However, without interceptive task requirements or actual ball flight information, significant variations in downswing initiation timing and peak bat velocities were demonstrated. Findings stress the need for representative experimental and learning designs in fast ball sports for developing performers.  相似文献

This research aimed to analyse interpersonal behaviour towards immigrants by exploring related psychosocial variables such as intergroup similarity and quality of intergroup contact. A new interpersonal behavioural tendencies scale was developed. In Study 1, Spanish participants reported their willingness to take different actions towards a Moroccan (i.e. a devalued target, n = 132) or an Ecuadorian (i.e. a valued target, n = 138), perceived intergroup similarity and quality of intergroup contact. Multigroup confirmatory factor analysis identified the expected dimensions: active facilitation (AF), passive facilitation (PF), passive harm (PH) and active harm (AH). Participants reported less similarity, less pleasant contact, less AF and less PF, and more PH with respect to Moroccans relative to Ecuadorians. Quality of contact mediated the effect of perceived similarity on interpersonal behaviour (especially facilitative behaviour) towards immigrants. Study 2 (N = 134) confirmed that this mediation effect also applied to Romanian immigrants, and tested a serial mediation pathway, in which perceived similarity affected symbolic threat, which in turn affected quality of contact, which finally affected behaviour. Changing perceived intergroup similarity might be a way of improving the quality of contact with minority groups, and this would be expected to increase pro‐social behaviour towards such groups.  相似文献

Depression is one of the main the psychological disorders in the gerontological population. However, in many cases the depressive alterations can go unnoticed or masked by the elderly s somatic complaints; or even the depressive symptoms can be ascribe to the own aging process. Moreover, it has to be added that old patients tend not to request help to specialised mental health centres. Therefore, the correct diagnosis of the depressed elderly's emotional problems becomes into a question of extraordinary importance. In this work is presented a new specific instrument for the evaluation of depression in the elderly people which has, among other characteristics, the advantage of requiring a little time to its application and a low knowledge on psychopathology. The initial results show an extraordinary sensitivity and specificity regarding to DSM-IV-TR criteria. Nevertheless, further studies with a higher number of clinical populations are necessary to confirm and enlarge these preliminary results.  相似文献

This study is framed in a wider research on the acculturation process through a new acculturation model. The aim of this paper is to analyse the mutual prejudice between ethnic groups in contact and its relation to their preferred acculturation attitude. A questionnaire composed by various scales was given to four groups of people living in municipalities with high rate of African immigrants in Almería: Maghrebis, Sub-Saharans, Spaniards who evaluated the Maghreb out-group and Spaniards who responded on the Sub-Saharan out-group. The results obtained indicate a relation between prejudice and acculturation attitude, as the lowest scores in prejudice are hold in each group by people preferring integration , whilst the highest ones come from those who bow to exclusion/marginalisation.  相似文献

Based on a conversational analysis of experimental procedures and consistent with the principle of relevance, we predicted that participants' verbal responses will be influenced by their tacit inferences about the researcher's epistemic goals, derived from their knowledge of the researcher's academic affiliation. We tested this prediction in a core area of social‐personality and cultural psychology, causal attribution. University students provided causal attributions about mass murder cases, while the questionnaire identified the researcher either as a social scientist or a personality psychologist. The results indicated that attributions were overall more situational than dispositional, and as predicted, this main effect was qualified by an interaction between conversational cue and type of attribution. Thus, participants gave relatively more situational explanations when the letterhead of the questionnaire identified the researcher as a social scientist compared to when the researcher was identified as a personality psychologist. The reverse pattern emerged for dispositional attributions. Methodological and conceptual implications are discussed. Copyright © 1999 John Wiley & Sons, Ltd.  相似文献

The main objective of this article is to address the impact of narrative practices in life celebration after the age of 80 and in the co-construction of a community-positive future. We share here an exploratory reflection about the narratives of a group of older women integrated in a community project. The Wednesday Tea Project (Chá das Quartas) has been ongoing for 4 years, and involves a group of old women experiencing high levels of loneliness and isolation in their small village in Portugal. The Wednesday Tea Project is based on positive psychology methodologies and consists of ritualized sessions that encourage participatory group dynamics. To describe how this project has highlighted the benefits of narrative practices, we utilized a series of scaffolding questions. Some of the most relevant outcomes of this project are: (a) the deconstruction of the dominant social discourse; (b) the publication of a book; (c) the reduction of loneliness feelings by re-membering significant figures; and (d) new levels of action both to women and the community as a consequence of a re-authoring process. Narrative practices seem to have contributed to the consolidation of all time dimensions, giving these women the opportunity to celebrate life after the age of 80, while also allowing the community to be part of and to benefit from the process. A reflection about the contributions of this article to a paradigm change toward positive aging is presented.  相似文献

Supernatural beliefs are ubiquitous around the world, and mounting evidence indicates that these beliefs partly rely on intuitive, cross-culturally recurrent cognitive processes. Specifically, past research has focused on humans' intuitive tendency to perceive minds as part of the cognitive foundations of belief in a personified God—an agentic, morally concerned supernatural entity. However, much less is known about belief in karma—another culturally widespread but ostensibly non-agentic supernatural entity reflecting ethical causation across reincarnations. In two studies and four high-powered samples, including mostly Christian Canadians and mostly Hindu Indians (Study 1, N = 2,006) and mostly Christian Americans and Singaporean Buddhists (Study 2, N = 1,752), we provide the first systematic empirical investigation of the cognitive intuitions underlying various forms of belief in karma. We used path analyses to (a) replicate tests of the previously documented cognitive predictors of belief in God, (b) test whether this same network of variables predicts belief in karma, and (c) examine the relative contributions of cognitive and cultural variables to both sets of beliefs. We found that cognitive tendencies toward intuitive thinking, mentalizing, dualism, and teleological thinking predicted a variety of beliefs about karma—including morally laden, non-agentic, and agentic conceptualizations—above and beyond the variability explained by cultural learning about karma across cultures. These results provide further evidence for an independent role for both culture and cognition in supporting diverse types of supernatural beliefs in distinct cultural contexts.  相似文献

Believers describe God as a strategic social agent who perceives human thoughts and actions. Thinking about God therefore might make believers feel as if their behavior is being monitored, a possibility we call the supernatural monitoring hypothesis. Three studies offered new and converging empirical support for this hypothesis using two variables that are sensitive to perceived social surveillance: public self-awareness and socially desirable responding. For believers, the effect of an explicit God prime on public self-awareness was comparable to the effect of thinking about how other people view oneself (Experiment 1). An implicit God concepts prime increased public self-awareness (Experiment 2) and socially desirable responding (Experiment 3) among believers. These studies offer the first direct evidence that thinking of God triggers perceived social surveillance.  相似文献
