This research examined whether self‐fulfilling prophecies and perceptual confirmation effects accumulated across people. Trios of same‐sex participants, each consisting of two interviewers and one target, were randomly assigned to one of three conditions that served to manipulate interviewers' expectations (i.e., non‐hostile vs. hostile) and the similarity of their expectations (i.e., similar vs. dissimilar) for targets. Each trio participated in an interaction in which interviewers asked targets questions. Targets' hostility during the interaction and interviewers' impressions of targets' hostility following the interaction served as the primary dependent variables. Results indicated that perceptual confirmation effects accumulated across interviewers. Even though targets' behavior during the interaction did not differ across conditions, interviewers nonetheless judged targets as more hostile when both interviewers expected targets to be hostile than when only one did. The authors discuss these findings in terms of the potential implications for those who have multiple inaccurate and unfavorable expectations held about them.

This study examined the long-term effects of the Better Beginnings, Better Futures project, a community-based early childhood development program, on 18–19 year-old youths’ narratives about turning points in their lives. The sample consisted of youth who participated in Better Beginnings from ages 4–8 (n = 62) and youth from a comparison community who did not participate in Better Beginnings (n = 34). Controlling for covariates, significant differences favoring youth from the Better Beginnings sites were found on several dimensions of the turning point stories: ending resolution, personal growth, meaning-making, coherence, and affect transformation. Effect sizes ranged from .45 to .76 for these outcome dimensions, indicating moderate to large effects. Also, turning point story dimensions were found to be significantly correlated with two standardized measures of well-being: youths’ self-esteem and community involvement. Youths’ self-esteem was directly related to story ending resolution, personal growth, and meaning making, and youths’ community involvement was directly related to story specificity, meaning making, and coherence. Family functioning was also examined in relation to these narrative dimensions but was not found to be significantly related to them. The findings suggest the utility of a narrative approach for the evaluation of the long-term outcomes of early childhood development programs.  相似文献

Few studies have examined connected speech in demented and non-demented patients with Parkinson’s disease (PD). We assessed the speech production of 35 patients with Lewy body spectrum disorder (LBSD), including non-demented PD patients, patients with PD dementia (PDD), and patients with dementia with Lewy bodies (DLB), in a semi-structured narrative speech sample in order to characterize impairments of speech fluency and to determine the factors contributing to reduced speech fluency in these patients. Both demented and non-demented PD patients exhibited reduced speech fluency, characterized by reduced overall speech rate and long pauses between sentences. Reduced speech rate in LBSD correlated with measures of between-utterance pauses, executive functioning, and grammatical comprehension. Regression analyses related non-fluent speech, grammatical difficulty, and executive difficulty to atrophy in frontal brain regions. These findings indicate that multiple factors contribute to slowed speech in LBSD, and this is mediated in part by disease in frontal brain regions.  相似文献

Child-mother attachment security, assessed via a modified Strange Situation procedure (Cassidy & Marvin, with the MacArthur Attachment Working Group, 1992), and parent-reported child proneness to anger were examined as correlates of observed child behavior toward mothers during a series of interactive tasks (N = 120, 60 girls). Controlling for maternal sensitivity and child gender and expressive language ability, greater attachment security, and lower levels of anger proneness were related to more child responsiveness to maternal requests and suggestions during play and snack sessions. As hypothesized, anger proneness also moderated several security-behavior associations. Greater attachment security was related to (a) more committed compliance during clean-up and snack-delay tasks for children high on anger proneness, (b) more self-assertiveness during play and snack for children moderate or high on anger proneness, and (c) more help-seeking during play and snack for children moderate or low on anger proneness. Findings further our understanding of the behavioral correlates of child-mother attachment security assessed during late toddlerhood via the Cassidy-Marvin system and underscore child anger proneness as a moderator of attachment-related differences in child behavior during this developmental period.  相似文献

People are quick to perceive meaningful patterns in the co-occurrence of events. We report two studies exploring the effects of streaks in symptom checklists on perceived personal disease risk. In the context of these studies, a streak is a sequence of consecutive items on a list that share the characteristic of being either general or specific. We identify a psychological mechanism underlying the effect of streaks in a list of symptoms and show that the effect of streaks on perceived risk varies with the length of the symptom list. Our findings reveal a tendency to infer meaning from streaks in medical and health decision making. Participants perceived a higher personal risk of having an illness when presented with a checklist in which common symptoms were grouped together than when presented with a checklist in which these same symptoms were separated by rare symptoms. This research demonstrates that something as arbitrary as the order in which symptoms are presented in a checklist can affect perceived risk of disease.  相似文献

5' adenosine monophosphate-activated protein kinase (AMPK) plays a prominent role as a metabolic stress sensor. The role of hypothalamic AMPK in response to restraint and surgical stress has not been previously investigated. It has been recently suggested that the renin-angiotensin system, in addition to its role in stress regulation, may play a significant role in regulating metabolic pathways including the regulation of the AMPK system. This study was thus aimed to evaluate the effects of candesartan, an angiotensin II AT1 receptor blocker drug, on hypothalamic AMPK activity under basal conditions and after restraint in conscious rats or after surgical stress under general anesthesia. Male Wistar rats were treated with 5 mg/kg/day candesartan in the drinking water for 2 weeks. The hypothalamic AMPK activity was determined under basal and stress conditions, using a kinase activity assay. Chronic administration of candesartan significantly increased hypothalamic AMPK activity. Hypothalamic AMPK activity was also increased by restraint stress whereas no change was observed during surgical stress under anesthesia. The high levels of hypothalamic AMPK activation observed in candesartan-treated rats were not changed by restraint stress but were reduced to control levels by anesthesia and surgery. In conclusion, chronic candesartan treatment and restraint stress in conscious rats stimulate the hypothalamic AMPK activity, whereas surgical stress under anesthesia inhibits pathways regulating the AMPK activity even in candesartan-treated rats.  相似文献

Depression and anxiety affect a person’s ability to move from hospital to community and engage in valued occupations. The purpose of this study was to understand the effectiveness of an occupational therapist-led transitional service for people with mood and anxiety disorders. Using a mixed-method design consisting of retrospective pre-post analysis of outcome measures and qualitative analysis of interviews with key stakeholders, statistically and clinically significant improvements were seen in depression and anxiety symptoms as well as occupational engagement after completion of the service. This study highlights the unique contributions of occupational therapist-led programing in mental health recovery.  相似文献

Abstract

Background: Public awareness of Transgender and Gender Diverse (TGD) identities has grown significantly; however, acceptance and support remain elusive for many TGD youth. Resultant experiences of marginalization and stigmatization contribute to elevated rates of psychological distress and suicidality among TGD youth. Emergent evidence suggests that the internet may offer TGD youth safety, support, and community previously unavailable.

Aim: The primary aim of this qualitative inquiry is to engage in an in-depth exploration of the online experiences and processes which help protect against psychological distress and promote well-being among TGD youth.

Methods: Data were culled from a mixed-methods, online study of sexual and gender minority youth from across the United States and Canada which followed Institutional Review Board approved protocols. Participants for this study represent a sample (n?=?260) of TGD participants aged 14–22 (x? = 17.30). Data were analyzed using Charmaz’ grounded theory strategies.

Results: Data revealed that the internet offers TGD youth affirming spaces that, for the most part, do not exist in their offline lives. Online, TGD youth were able to engage meaningfully with others as their authentic selves, often for the first time. These experiences fostered well-being, healing, and growth through five processes: 1. Finding an escape from stigma and violence, 2. Experiencing belonging, 3. Building confidence, 4. Feeling hope, and 5. Giving back.

Discussion: The unique and innovative ways in which participants use online spaces to foster resilience offer important insights to inform affirmative practices with TGD young people.  相似文献
