Childhood Trauma, Adult Sexual Assault, and Adult Gender Expression among Lesbian and Bisexual Women
Several studies have demonstrated that lesbian and bisexual women are more likely than heterosexual women to report childhood abuse and adult sexual assault. It is unknown, however, which sexual minority women are most likely to experience such abuse. We recruited adult sexual minority women living in the US through electronic fliers sent to listservs and website groups inviting them to complete an online survey (N?=?1,243). We examined differences in both childhood abuse and adult sexual assault by women’s current gender identity (i.e., butch, femme, androgynous, or other) and a continuous measure of gender expression (from butch/masculine to femme/feminine), adjusting for sexual orientation identity, age, education, and income. Results indicated that a more butch/masculine current self-assessment of gender expression, but not gender identity, was associated with more overall reported childhood trauma. Although one aspect of gender expression, a more butch/masculine gender role, was associated with adult sexual assault, feminine appearance and a femme gender identity also significantly predicted adult sexual assault. These findings highlight the significance of gender identity and expression in identifying women at greater risk for various abuse experiences. 相似文献

People learn from the texts that they read, but sometimes what they read is wrong. Previous research has demonstrated that individuals encode even obvious inaccuracies, at times relying on the misinformation to complete postreading tasks. In the present study, we investigated whether the influence of inaccurate information might be reduced by encouraging the retrieval of accurate knowledge. Participants read an extended text that contained both accurate and inaccurate assertions, after which they evaluated the validity of statements associated with those assertions. In general, participants made more mistakes in their evaluations of statements after having read inaccurate as compared to accurate assertions, offering evidence of the influence of misinformation. However, when participants were tasked with correcting inaccuracies during reading, their mistakes were substantially reduced. Encouraging the retrieval of accurate knowledge during reading can reduce the influence of misinformation. These findings are discussed with respect to the contributions of episodic traces and prior knowledge on learning, as well as to the conditions that support successful comprehension. 相似文献

This study examines whether humility is associated with gender, education, and racial/ethnic group. We also investigate how social relations mediate these links across the life course. Data are from the Detroit Community Study, which focused on three prominent groups in the area: Arab Americans, African Americans, and White Americans (N=907). Findings indicate that Arab Americans and African Americans report greater humility than Whites. Further, social relations partially mediate this association, but only among older Arab Americans. Findings are discussed within a developmental science perspective to consider the relational aspects of the individual and context over the life course. 相似文献

Low family socioeconomic status (SES) is a robust risk factor for adverse child outcomes, yet the specific processes that account for this risk are not fully understood. This study examines whether and how variation in two adverse factors, stressful life events and harsh parental discipline, affect children’s social competence within a high-risk environment, and whether some children are more vulnerable to these effects than others. Data were collected from 207 families of kindergarten children at risk for behavioral maladjustment. Children’s physiological regulation (respiratory sinus arrhythmia; RSA) measured during rest was examined as a moderator of risk exposure. Results indicate that both greater exposure to life stress and harsh discipline were correlated with lower social competence. Although children’s resting RSA was not a direct predictor of their social competence, it moderated the association between life stress and social competence. Greater exposure to life stress was more strongly associated with lower social competence among children with lower resting RSA. Higher RSA may help to buffer the effects of stress and facilitate appropriate social development. RSA did not moderate the effects of harsh discipline. This differential pattern of findings suggests that children’s physiological regulation can facilitate an effective response to situational stressors, but may be less efficacious in buffering against stress in the context of the parent-child relationship. 相似文献

Taste aversion learning (TAL) is a type of learning characterized by rejection of a gustatory/flavor stimulus as a consequence of its pairing with visceral discomfort and malaise. TAL can be established in the laboratory by two different behavioral procedures, concurrent or sequential. Neural mechanisms of these learning modalities remain to be elucidated, but several studies have discussed the implication of various anatomical structures, including the vagus nerve. The aim of this study was to examine the role of capsaicin-sensitive vagal afferent fibers in concurrent (Experiment 1) and sequential (Experiment 2) TAL in Wistar rats. Results showed that perivagal administration of capsaicin (1mg of capsaicin dissolved in 1ml of vehicle (10% Tween 80 in oil)) blocked acquisition of concurrent but not sequential TAL. These data support the hypothesis of two different modalities of TAL mediated by distinct neurobiological systems, with vagal nerve participation only being essential in concurrent TAL. 相似文献

In the present study, we investigated age-related changes in interactions between efficiency of neuronal repair mechanisms
and efficiency of cholinergic neurotransmission in the context of attentional orienting. In addition, we explored white matter
volume changes as possible neuronal underpinnings. A sample of 230 healthy middle-aged (53–64 years) and older (65–75 years)
adults was genotyped for polymorphisms of APOE and CHRNA4, a nicotinic receptor subunit gene. Participants were administered
a visuospatial attention task involving letter discrimination with location cues of varying validity. Genotype effects on
white matter volume were also investigated in a subset of participants who received MRI scans. APOE interacted with CHRNA4,
such that APOE-ε4 carriers who were also CHRNA4 TT homozygotes showed disproportionately slowed reaction time (RT) following
invalid location cues. The interaction was stronger in the middle-aged participants than in the older participants. There
was also a trend for individuals with combined APOE-ε4/CHRNA4 TT genotypes to show both lower white matter volume and slower
overall RT on the attention task. The interaction of a neurotransmission gene (CHRNA4) and a susceptibility gene (APOE) suggests
that the efficiency of neuronal repair mechanisms may modulate the cholinergic system to influence attentional function. 相似文献

The incidence of Autism Spectrum Disorder (ASD) has increased over the past decade suggesting a need for further research. This article describes a two phase phenomenological study which explored the lived experience of ASD and its psychosocial effects on relationships, socialization, and occupational participation. Phenomenological interviews were given to three women and three men with high functioning ASD. Phase two of the research included two additional individual interviews and four focus groups. Results indicated themes regarding participants' desires to engage in social occupations, and barriers caused by the nature of the ASD which may successfully be addressed by occupational therapy. 相似文献

Children with hydrocephalus have deficits in several neuropsychological domains. The most notable are motor, visuoperceptual, and visuomotor function. These deficits are multiply determined and depend on the etiology and severity of the hydrocephalus to a large extent. Corpus callosum abnormalities resulting from stretching of callosal fibers and other cortical white matter tracts are implicated as contributory to these deficits. Enlarged ventricles and associated compression of posterior cortical areas also correlate with cognitive impairment. Distinguishing which cognitive domain negatively impacts on the child’s functioning and which domains influence behavior in isolation or in combination has been the subject of numerous studies. Developmentally, we know little about the emergence of neuropsychological functioning in children with hydrocephalus. Study of the effects of hydrocephalus at different stages of development is useful to clinicians and researchers interested in the impact of diffuse neurophysiological damage on cognition in the developing brain. The medical and neuropsychological literature have begun to inform about these effects. The core deficits in hydrocephalus have yet to be explicated and a focus on investigations that answer these questions is required. This review summarizes the current knowledge about neurocognitive sequelae of hydrocephalus. 相似文献

Studies have replicated both negative and positive associations between helpless attributional style and academic performance. Laboratory studies indicate that when enhancement effects occur, they may be moderated by the degree of failure individuals experience prior to task performance. In a longitudinal study of 96 college students who completed four examinations in two introductory psychology courses, we examined the relationship between helpless attributional style and examination performance across the semester, and whether prior examination failure moderated this association. Correlational analyses revealed that helpless attributional style was unrelated to exam performance in the first half of the semester and was positively related to improvements in performance in the second half. Regression analyses indicated that these enhancement effects were not moderated by previous performance on examinations in the course. The present findings underscore the need for longitudinal studies that investigate the pattern of associations between helpless attributional style and performance across time in real-life contexts. 相似文献
