Trichotillomania (TTM), a repetitive hair-pulling disorder, is underrepresented in the clinical literature. The current project explores the relationship between affective regulation and disordered hair-pulling. Previous research suggests that cycles of emotional states are correlated with the disorder and may induce, reinforce, or otherwise contribute to hair-pulling behavior. We use anonymous internet survey responses from 1162 self-identified hair-pullers to address four questions about affective regulation in people with TTM: (1) Do hair-pullers experience greater difficulty “snapping out” of affective states than non-pullers? (2) Does difficulty with emotional control correlate with TTM severity? (3) Are subtypes identifiable based on the emotions that trigger hair-pulling behavior? (4) Does difficulty “snapping out” of an emotion predict whether that emotion triggers pulling behavior? The results showed a small-to-moderate relationship between affective regulation and problematic hair-pulling. In addition, individual patterns of emotion regulation were systematically related to emotional cues for hair-pulling as well as overall hair-pulling severity. These findings contribute to an understanding of the phenomenology of TTM and provide empirical support for treatments focused on affect regulation. 相似文献

We examined midlife educational, career, and family outcomes of women who attended prestigious women's colleges in the 1960s. One college had a coeducational learning environment (CLE), the other was a single-sex environment (SLE). We hypothesized that in CLEs, exposure to men's standards of achievement might have resulted in greater educational and career status outcomes but more discrimination; in SLEs, there might have been fewer opportunities to engage with men intellectually, which could lead to lesser educational and career status outcomes, but the environment might have felt more supportive. Graduates of both colleges were very accomplished 30 years after graduation; however, those who had experienced a CLE reported more sexism and more active involvement in the women's movement than SLE graduates. 相似文献

The purpose of the current study was to operationalize the phenomenon of body deception, describe its theoretical importance, and validate its existence in an experimental paradigm. The definition of body deception includes the intentional misrepresentation of information about appearance to others. The present study examined body deception in a controlled experimental study of male and female same-sex peer groups using a series of hierarchical linear models. Ninety male and 90 female undergraduates were randomized to an experimental same-sex peer group or individual control condition. The results suggested that both men and women used body deception among peers, but men's body deception was muscularity driven whereas women's was thinness driven. Body dissatisfaction was significantly predictive of the degree of body deception used by both genders and it was significantly related to peer group membership. An integrated model for the role of body deception in body image disturbance is proposed. 相似文献

Using data from two longitudinal studies of educated white women, we explored precursors and correlates of ego integrity versus despair, which is the last developmental stage in Erikson’s theory of adult development. The women comprising Study 1 graduated from Smith College in 1964 (N = 42); the women comprising Study 2 graduated from Radcliffe College also in 1964 (N = 50). In both studies, hierarchical regressions indicated that women who had resolved their regrets at age 53 achieved higher levels of ego integrity at age 62, and those who had resolved their regrets at age 62 also had higher concurrent levels of ego integrity. Further, in study 2, generativity at age 53 was found to predict ego integrity at age 62. 相似文献

Source memory has consistently been associated with prefrontal function in both normal and clinical populations. Nevertheless, the exact contribution of this brain region to source memory remains uncertain, and evidence suggests that processes used by young and older adults may differ. The authors explored the extent to which scores on composite measures of neuropsychological tests of frontal and medial temporal function differentially predicted the performance of young and older adults on source memory tasks. Results indicated that a frontal composite measure, consistently associated with source memory performance in older adults, was unrelated to source memory in young adults, although it was sensitive to a demanding working memory task. The memory composite score, however, predicted performance in the young group. In addition, item and source memory were correlated in young but not older people. Findings are discussed in terms of age-related differences in working memory and executive functions, and differential binding processes necessary for item and source memory. The requirement to integrate item and source information at encoding appears to place greater demands on executive or working memory processes in older adults than in younger adults. 相似文献

Rodent ultrasonic vocalizations (USVs) are ethologically critical social signals. Rats emit 22 kHz USVs and 50 kHz USVs, respectively, in conjunction with negative and positive affective states. Little is known about what controls emotional reactivity to these social signals. Using male Sprague–Dawley rats, we examined unconditional and conditional freezing behavior in response to the following auditory stimuli: three 22 kHz USVs, a discontinuous tone whose frequency and on–off pattern matched one of the USVs, a continuous tone with the same or lower frequencies, a 4 kHz discontinuous tone with an on–off pattern matched to one of the USVs, and a 50 kHz USV. There were no differences among these stimuli in terms of the unconditional elicitation of freezing behavior. Thus, the stimuli were equally neutral before conditioning. During differential fear conditioning, one of these stimuli (the CS+) always co-terminated with a footshock unconditional stimulus (US) and another stimulus (the CS−) was explicitly unpaired with the US. There were no significant differences among these cues in CS+-elicited freezing behavior. Thus, the stimuli were equally salient or effective as cues in supporting fear conditioning. When the CS+ was a 22 kHz USV or a similar stimulus, rats discriminated based on the principal frequency and/or the temporal pattern of the stimulus. However, when these same stimuli served as the CS−, discrimination failed due to generalization from the CS+. Thus, the stimuli differed markedly in the specificity of conditioning. This strikingly asymmetrical stimulus generalization is a novel bias in discrimination. 相似文献

The Implementation of Modified Parent-Child Interaction Therapy for Youth with Separation Anxiety Disorder 总被引:1,自引:1,他引:0

Separation Anxiety Disorder (SAD) is the most prevalent anxiety disorder experienced by children, and yet empirical treatment studies of SAD in young children are virtually nonexistent. This paper will describe the development and implementation of an innovative treatment for SAD in young children. First, we will highlight the rationale for developing interventions specifically for SAD in young children. Second, we will describe an existing empirically supported treatment, Parent-Child Interaction Therapy (PCIT; Brinkmeyer, M. Y., & Eyberg, S.M., (2003)), that may have particular applicability to very young children with SAD and their parents. We present how results from 10 pilot participants were utilized to modify PCIT to better address the needs of children with SAD and their families. The benefits and challenges of implementing this modified version of PCIT are reviewed, along with potential directions for future research in this area. 相似文献

From insects to humans, successful navigation relies on retained representations of spatial relations. These representations are thought to depend on the hippocampal formation, particularly those that are independent of the navigator (allocentric representations). The Morris water maze is a simple and popular task often used to assess spatial navigation. But how animals navigate toward and retain information regarding the location of the goal in this task remains unclear. We provide a comprehensive account of how the water maze is accomplished behaviourally. Our findings suggest that animals solve the task using distal cues via an initial view-matching strategy that is supported by egocentric guidance. Through increased training, however, an emergence of an egocentric-guiding strategy combined with the animal’s greater ability to infer the hidden platform’s location (via allocentric extrapolation) emerges. We also demonstrate that behavioural changes, towards a more allocentric strategy, are reflected in increases in hippocampal brain-derived neurotrophic factor. 相似文献
