Background and objectives: Psychosocial factors, such as gender role norms, may impact how social anxiety disorder (SAD) is experienced and expressed in different social contexts for women. However to date, these factors have not been examined via experimental methodology. Design: This was a cross-sectional, quasi-experimental controlled study. Methods: The current study included 48 highly socially anxious (HSA) women (70.9% meeting criteria for SAD) and examined the relationships among psychosocial factors (i.e. gender role self-discrepancies and self-perceived physical attractiveness), self-perceived social performance, and state anxiety, across two in vivo social tasks (i.e. conversation and opinion speech). Results: On average, participants reported belief that they ought to be less feminine for the speech task and more masculine for both the conversation and speech tasks. Also, for the conversation task, only lower self-rated attractiveness predicted poorer self-perceived performance and greater post-task state anxiety, above gender role self-discrepancies and confederate gender. For the speech task, only greater self-discrepancy in prototypical masculine traits predicted poorer performance ratings, and it was related to greater state anxiety in anticipation of the task. Conclusion: For HSA women, psychosocial factors may play different roles in social anxiety across social contexts.  相似文献

Background and objectives: Prior research suggests that altering situation-specific evaluations of stress as challenging versus threatening can improve responses to stress. The aim of the current study was to explore whether cognitive, physiological and affective stress responses can be altered independent of situation-specific evaluations by changing individuals’ mindsets about the nature of stress in general.

Design: Using a 2?×?2 design, we experimentally manipulated stress mindset using multi-media film clips orienting participants (N?=?113) to either the enhancing or debilitating nature of stress. We also manipulated challenge and threat evaluations by providing positive or negative feedback to participants during a social stress test.

Results: Results revealed that under both threat and challenge stress evaluations, a stress-is-enhancing mindset produced sharper increases in anabolic (“growth”) hormones relative to a stress-is-debilitating mindset. Furthermore, when the stress was evaluated as a challenge, a stress-is-enhancing mindset produced sharper increases in positive affect, heightened attentional bias towards positive stimuli, and greater cognitive flexibility, whereas a stress-is-debilitating mindset produced worse cognitive and affective outcomes.

Conclusions: These findings advance stress management theory and practice by demonstrating that a short manipulation designed to generate a stress-is-enhancing mindset can improve responses to both challenging and threatening stress.  相似文献

Selective eating (often referred to as “picky” eating) is common in individuals with autism spectrum disorder (ASD) across the lifespan. Behavioral interventions are widely used to treat selective eating; however, most of these programs are time intensive, have not been evaluated for use in outpatient settings, and do not typically include youth beyond early childhood. Despite the functional impact and risk for negative outcomes associated with selective eating, there are no empirically supported treatments available for older children, adolescents, or adults, either with or without ASD. To address this treatment gap, we developed BUFFET: the Building Up Food Flexibility and Exposure Treatment program. BUFFET is a 14-week, multi-family group cognitive behavioral treatment for selective eating in children (8–12 years) with ASD. In this paper, we will (1) discuss the theoretical conceptualization of BUFFET, (2) describe the treatment content and structure, (3) present feasibility data from the initial pilot trial, and (4) consider next steps in treatment development.  相似文献

Adults automatically infer a person’s social disposition and future behavior based on the many properties they observe about how they look and sound. The goal of the current study is to explore the developmental origins of this bias. We tested whether 12-month-old infants automatically infer a character’s social disposition (e.g., whether they are likely to “help” or “hinder” another character’s goal) based on the sounds and visual features those characters display. Infants were habituated to 2 characters, 1 that possessed more positive properties (e.g., a soft, fluffy appearance and a happy-sounding laugh) or more negative properties (e.g., a sharp, pointy appearance and a deep, ominous laugh). During test trials, we observed that infants looked longer at events that involved characters engaging in social actions toward another that were inconsistent rather than consistent with the valence of how they looked and sounded during habituation. Two control conditions support the interpretation that infants’ responses were based on an inferred causal relationship between a character’s features and its disposition rather than on some noncausal associations between the positive and negative valences of the characteristics and actions. Together, these studies suggest that infants are biased to connect an agent’s audiovisual features to their social behavior.  相似文献

The number of individuals receiving hospice care in the United States is on the rise. Many individuals who suffer from debilitating health issues use the care of helping professionals in a hospice environment. Supervision approaches for counselors who encounter grief, loss, death, and bereavement issues in hospice settings are needed. The authors introduce three creative interventions for use with supervisees in one of the four stages of the integrative developmental model of supervision. One intervention, the “Rock Talk,” is more thoroughly explained and then demonstrated in a case illustration of a supervisee using the intervention to say goodbye to a hospice client.  相似文献

Previous research has shown that bilinguals outperform monolinguals on a variety of tasks that have been described as involving executive functioning, but the precise mechanism for those effects or a clear definition for “executive function” is unknown. This uncertainty has led to a number of studies for which no performance difference between monolingual and bilingual adults has been detected. One approach to clarifying these issues comes from research with children showing that bilinguals were more able than their monolingual peers to perceive both interpretations of an ambiguous figure, an ability that is more tied to a conception of selective attention than to specific components of executive function. The present study extends this notion to adults by assessing their ability to see the alternative image in an ambiguous figure. Bilinguals performed this task more efficiently than monolinguals by requiring fewer cues to identify the second image. This finding has implications for the role of selective attention in performance differences between monolinguals and bilinguals.  相似文献

Two experiments were conducted to evaluate the ability of younger and older adults to recognize 3-D object shape from patterns of optical motion. In Experiment 1, participants were required to identify dotted surfaces that rotated in depth (i.e., surface structure portrayed using the kinetic depth effect). The task difficulty was manipulated by limiting the surface point lifetimes within the stimulus apparent motion sequences. In Experiment 2, the participants identified solid, naturally shaped objects (replicas of bell peppers, Capsicum annuum) that were defined by occlusion boundary contours, patterns of specular highlights, or combined optical patterns containing both boundary contours and specular highlights. Significant and adverse effects of increased age were found in both experiments. Despite the fact that previous research has found that increases in age do not reduce solid shape discrimination, our current results indicated that the same conclusion does not hold for shape identification. We demonstrated that aging results in a reduction in the ability to visually recognize 3-D shape independent of how the 3-D structure is defined (motions of isolated points, deformations of smooth optical fields containing specular highlights, etc.).  相似文献

ABSTRACT

This study used synthesis to manipulate vowel formant frequencies and durations to evaluate their role on foreign accent perception. Formant frequencies and durations for the vowels /æ/, /?/, and /a/ were manipulated with changes toward and away from the mean native English and Spanish-accented values from Sidaras, S. K., Alexander, J. E. D., & Nygaard, L. C. (2009. Perceptual learning of systematic variation in Spanish-accented speech. The Journal of the Acoustical Society of America, 125, 3306–3316). Native listeners rated these stimuli on degree of accentedness and comprehensibility. Gradual changes in formant frequencies from native to non-native values impacted /a/ negatively, /?/ positively, and /æ/ minimally. Effects of vowel duration on either type of ratings were small and restricted to vowel-specific interactions. The current findings suggest that vowel formant frequencies are primary cues to foreign accent. Their influence depends upon whether or not frequencies could reflect alternative vowel categories.  相似文献

Exposure to prenatal stress (PNS) has been shown to induce a set of psychological and behavioral changes in developing offspring. We used the rodent model to investigate whether PNS produces changes in the ability of the pup to express social motivation. We used a set of behavioral tasks including monitoring ultrasonic vocalizations after isolation, a conditioned place preference, and a novel and familiar odor approach test. Pregnant Long-Evans rats were exposed to an unpredictable, variable stressor twice daily during the third week of gestation. Isolation vocalizations were assessed on postnatal day (PND) 10. Pup affinity for the dam was evaluated on PND 15. Typically, pups display a selective preference for an odor-paired environment only after the odor has been associated with the dam. This previous association produces a positive conditioned stimulus (CS). Normally, pups exposed to a neutral CS (odor paired with cotton balls) do not form this place preference. Results indicate that PNS exposed pups had significantly increased distress vocalizations and an equal preference for the positive and neutral conditioned stimuli. This type of alteration in forming early preferences could be detrimental because of decreases in the specificity of social learning and an impaired responsiveness in social relationships.  相似文献
