Over the past two decades, expressive writing interventions have been used successfully to reduce distress and improve well-being for those dealing with traumatic events, stressors, and illnesses. The purpose of this study was to investigate an expressive writing intervention for lesbian-related stressors. As expected, writing about traumatic events related to sexual orientation reduced self-reported confusion and perceived stress over a 2-month period for those lesbians who were less open about their sexual orientation. Interestingly, writing about such traumatic experiences was associated with increases in confusion and perceived stress for those who were more open about their sexual orientation. Applying this paradigm to assist individuals in coping with stressors related to their sexual orientation represents an important addition to the expressive writing literature. Furthermore, it offers a promising, cost-effective method to assist closeted lesbians in coping with stressors related to their sexual orientation.  相似文献

This study investigated ethnic differences in the extent to which engagement (i.e., attendance and quality of participation) in the PACE (Parenting our Children to Excellence) program predicted positive child and parent outcomes. PACE is an 8-week preventive intervention aimed at parents of preschool children. The study investigated the relation of engagement to outcomes in an ethnically diverse sample of 298 African American and 280 European American parents. Overall results demonstrated that engagement in PACE significantly improved child and parent outcomes for both African American and European American participants. Some improvements were evident at post-assessment already and were maintained or became stronger at a one-year follow-up assessment, whereas others only became evident at follow-up. Specifically, results revealed that attendance in PACE significantly improved child coping competence and parenting stress for both the African American and European American samples. PACE attendance also significantly improved child behavior problems, parental satisfaction and parental efficacy for the European American sample. Findings indicate that PACE is a promising intervention for parents of African American and Caucasian preschoolers; although further research and program refinement is necessary in order to understand the mechanisms with the PACE intervention that seem to vary for African American compared to Caucasian families.  相似文献

Infants have been described as ‘statistical learners’ capable of extracting structure (such as words) from patterned input (such as language). Here, we investigated whether prior knowledge influences how infants track transitional probabilities in word segmentation tasks. Are infants biased by prior experience when engaging in sequential statistical learning? In a laboratory simulation of learning across time, we exposed 9- and 10-month-old infants to a list of either disyllabic or trisyllabic nonsense words, followed by a pause-free speech stream composed of a different set of disyllabic or trisyllabic nonsense words. Listening times revealed successful segmentation of words from fluent speech only when words were uniformly disyllabic or trisyllabic throughout both phases of the experiment. Hearing trisyllabic words during the pre-exposure phase derailed infants’ abilities to segment speech into disyllabic words, and vice versa. We conclude that prior knowledge about word length equips infants with perceptual expectations that facilitate efficient processing of subsequent language input.  相似文献

Three studies examined generational differences in life goals, concern for others, and civic orientation among American high school seniors (Monitoring the Future; N = 463,753, 1976-2008) and entering college students (The American Freshman; N = 8.7 million, 1966-2009). Compared to Baby Boomers (born 1946-1961) at the same age, GenX'ers (born 1962-1981) and Millennials (born after 1982) considered goals related to extrinsic values (money, image, fame) more important and those related to intrinsic values (self-acceptance, affiliation, community) less important. Concern for others (e.g., empathy for outgroups, charity donations, the importance of having a job worthwhile to society) declined slightly. Community service rose but was also increasingly required for high school graduation over the same time period. Civic orientation (e.g., interest in social problems, political participation, trust in government, taking action to help the environment and save energy) declined an average of d = -.34, with about half the decline occurring between GenX and the Millennials. Some of the largest declines appeared in taking action to help the environment. In most cases, Millennials slowed, though did not reverse, trends toward reduced community feeling begun by GenX. The results generally support the "Generation Me" view of generational differences rather than the "Generation We" or no change views.  相似文献

This study used the Still Face Paradigm to investigate the relationship of maternal interaction on infants' emotion regulation responses. Seventy infant-mother dyads were seen at 4 months and 25 of these same dyads were re-evaluated at 9 months. Maternal interactions were coded for attention seeking and contingent responding. Emotional regulation was described by infant stress reaction and overall positive affect. Results indicated that at both 4 and 9 months mothers who used more contingent responding interactions had infants who showed more positive affect. In contrast, mothers who used more attention seeking play had infants who showed less positive affect after the Still Face Paradigm. Patterns of stress reaction were reversed, as mothers who used more attention seeking play had infants with less negative affect. Implications for intervention and emotional regulation patterns over time are discussed.  相似文献

Previous studies on autism have shown a lack of motor anticipation in children and adults with autism. As part of a programme of research into early detection of autism, we focussed on an everyday situation: spoon-feeding. We hypothesize that an anticipation deficit may be found very early on by observing whether the baby opens his or her mouth in anticipation of the spoon's approach. The study is based on a retrospective analysis from family home movies. Observation of infants later diagnosed with autism or an autism spectrum disorder (ASD) (n = 13) and infants with typical development (n = 14) between 4 and 6 months old show that the autism/ASD group has an early anticipation deficit.  相似文献

Institutional review boards assume that questionnaires asking about "sensitive" topics (e.g., trauma and sex) pose more risk to respondents than seemingly innocuous measures (e.g., cognitive tests). We tested this assumption by asking 504 undergraduates to answer either surveys on trauma and sex or measures of cognitive ability, such as tests of vocabulary and abstract reasoning. Participants rated their positive and negative emotional reactions and the perceived benefits and mental costs of participating; they also compared their study-related distress with the distress arising from normal life stressors. Participants who completed trauma and sex surveys, relative to participants who completed cognitive measures, rated the study as resulting in higher positive affect and as having greater perceived benefits and fewer mental costs. Although participants who completed trauma and sex surveys reported slightly higher levels of negative emotion than did participants who completed cognitive measures, averages were very low for both groups, and outliers were rare. All participants rated each normal life stressor as more distressing than participating in the study. These results suggest that trauma and sex surveys pose minimal risk.  相似文献
