This longitudinal, population-based and prospective study investigated the stability, age-related changes, and socio-emotional outcomes of shyness from infancy to early adolescence. A sample of 921 children was followed from ages 1.5 to 12.5?years. Parent-reported shyness was assessed at five time points and maternal- and self-reported social skills and symptoms of anxiety and depression were assessed at age 12.5?years. Piecewise latent growth curve analysis was applied, with outcomes regressed on latent shyness intercept and slope factors. Results showed moderate stability and increasing levels of shyness across time, with more variance and a steeper increase in early as compared to mid-to-late childhood. Both stable shyness and increased shyness in mid-to-late (but not early) childhood predicted poorer social skills and higher levels of anxiety and depression symptoms in early adolescence. The implications of the evidence for two developmental periods in shyness trajectories with differential impact on later socio-emotional functioning are discussed.  相似文献

While the gender gap in mathematics and science has narrowed, men pursue these fields at a higher rate than women. In this study, 165 men and women at a university in the northeastern United States completed implicit and explicit measures of science stereotypes (association between male and science, relative to female and humanities), and gender identity (association between the concept “self” and one’s own gender, relative to the concept “other” and the other gender), and reported plans to pursue science-oriented and humanities-oriented academic programs and careers. Although men were more likely than women to plan to pursue science, this gap in students’ intentions was completely accounted for by implicit stereotypes. Moreover, implicit gender identity moderated the relationship between women’s stereotypes and their academic plans, such that implicit stereotypes only predicted plans for women who strongly implicitly identified as female. These findings illustrate how an understanding of implicit cognitions can illuminate between-group disparities as well as within-group variability in science pursuit.  相似文献

Mother-child play of maltreating and nonmaltreating families was analyzed when infants were 12 months old (Time 1), and 2 years old (Time 2), as a context to examine children's developing cognitive and social skills. At Time 1, infants from abusing families demonstrated less independent and more imitative behavior during play than did infants from neglecting and nonmaltreating families, suggesting a delay in emerging social behaviors. In this longitudinal follow-up, mother-child play was reassessed 1 year later (N = 78), with a focus on children's engagement in nonplay and pretend play and on children's abilities to initiate social exchanges and respond to parental requests. Play and social behavior were coded from semistructured and unstructured play paradigms at both time points. Maternal attention-directing behavior and limit setting also was assessed. At Time 2, children from abusing, neglecting, and nonmaltreating families did not differ in cognitive play complexity. However, children from abusing families engaged in less child-initiated play than did children from neglecting and nonmaltreating families, demonstrating less socially competent behavior. Longitudinal analyses revealed child initiated play at Time 2 was negatively associated with abuse and with maternal physical attention directing behavior at Time 1. Child negative reactivity at Time 2 was positively associated with Time 1 maternal physical behavior and child imitation and with Time 2 maternal controlling behavior. Implications for early intervention efforts are emphasized.  相似文献

The current study investigated potential emotional priming effects on Minnesota Multiphasic Personality Inventory-2 (MMPI-2) scale scores. Participants included 98 college students who completed a personal narrative intended to induce temporary mood states, the MMPI-2, and a mood rating inventory. Results of the mood manipulation indicated that the individuals who first wrote a negative personal narrative reported a less positive mood (d = -.79). However, analysis of variance results indicated no statistically significant differences on MMPI-2 scale scores between groups (median η(2) = .005). Limitations and future directions are discussed.  相似文献

Research evidence has been accumulating for the efficacy of dialectical behaviour therapy (DBT) for binge eating. However, support for its effectiveness and transportability beyond efficacy trials is lacking. The current study evaluated the feasibility of group-based DBT for binge eating within the context of an operating community clinic. Women ages 24-49 (M?=?39.60, SD?=?9.53) with either subthreshold and full-threshold binge eating disorder or bulimia nervosa formed the group and comprised the sample (n?=?5 treatment completers). Positive outcomes included significant improvement in both binge eating and secondary outcomes with the Eating Disorder Inventory subscales of Bulimia, Ineffectiveness, Perfectionism and Interpersonal Distrust. Attrition was elevated compared with previous efficacy trials, suggesting the need for increased attention to how to improve retention within routine practice settings. Given our limited sample size, these findings are viewed as promising but preliminary.  相似文献

Two chronic, nonfluent aphasia patients participated in overt naming fMRI scans, pre- and post-a series of repetitive transcranial magnetic stimulation (rTMS) treatments as part of a TMS study to improve naming. Each patient received 10, 1-Hz rTMS treatments to suppress a part of R pars triangularis. P1 was a ‘good responder’ with improved naming and phrase length; P2 was a ‘poor responder’ without improved naming.Pre-TMS (10 years poststroke), P1 had significant activation in R and L sensorimotor cortex, R IFG, and in both L and R SMA during overt naming fMRI (28% pictures named). At 3 mo. post-TMS (42% named), P1 showed continued activation in R and L sensorimotor cortex, R IFG, and in R and L SMA. At 16 mo. post-TMS (58% named), he also showed significant activation in R and L sensorimotor cortex mouth and R IFG. He now showed a significant increase in activation in the L SMA compared to pre-TMS and at 3 mo. post-TMS (p < .02; p < .05, respectively). At 16 mo. there was also greater activation in L than R SMA (p < .08). At 46 mo. post-TMS (42% named), this new LH pattern of activation continued. He improved on the Boston Naming Test from 11 pictures named pre-TMS, to scores ranging from 14 to 18 pictures, post-TMS (2–43 mo. post-TMS). His longest phrase length (Cookie Theft picture) improved from three words pre-TMS, to 5–6 words post-TMS.Pre-TMS (1.5 years poststroke), P2 had significant activation in R IFG (3% pictures named). At 3 and 6 mo. post-TMS, there was no longer significant activation in R IFG, but significant activation was present in R sensorimotor cortex. On all three fMRI scans, P2 had significant activation in both the L and R SMA. There was no new, lasting perilesional LH activation across sessions for this patient. Over time, there was little or no change in his activation. His naming remained only at 1–2 pictures during all three fMRI scans. His BNT score and longest phrase length remained at one word, post-TMS.Lesion site may play a role in each patient’s fMRI activation pattern and response to TMS treatment. P2, the poor responder, had an atypical frontal lesion in the L motor and premotor cortex that extended high, near brain vertex, with deep white matter lesion near L SMA. P2 also had frontal lesion in the posterior middle frontal gyrus, an area important for naming (Duffau et al., 2003); P1 did not. Additionally, P2 had lesion inferior and posterior to Wernicke’s area, in parts of BA 21 and 37, whereas P1 did not.The fMRI data of our patient who had good response following TMS support the notion that restoration of the LH language network is linked in part, to better recovery of naming and phrase length in nonfluent aphasia.  相似文献

Patient letters provide a permanent record of the genetic counseling that was provided and are unique in medical care; rarely do other health care providers send summaries written specifically to their patients and families. We surveyed genetic counseling training program directors and found that while the acquisition of patient letter-writing skills was considered important, there were no specific guidelines made available to students. To develop letter-writing guidelines, we evaluated patient letters, reviewed references on professional correspondence, surveyed the medical literature, and worked with a writing consultant. The guidelines we subsequently developed and present here include a format for writing patient letters, suggestions on presenting medical information in understandable terms, and wording considerations. These patient letter-writing guidelines are intended to serve as a guide for teaching students this important skill and as a resource for practicing health care professionals.  相似文献

A model integrating Japanese ethnicity, cultural identity, and anxiety was developed and assessed in Japanese American and part-Japanese American high school seniors (N = 141). Using measures from the Hawaiian High Schools Health Survey, the model incorporated the State-Trait Anxiety Inventory, the Major Life Events Scale, and the Japanese Culture Scale (JCS). Japanese American adolescents scored higher on the JCS and reported fewer anxiety symptoms than part-Japanese American adolescents. Predictors for anxiety were being Japanese American versus part-Japanese American, income, and culturally intensified events. A significant interaction of behavior by self-identification was obtained. The model had good overall fit, suggesting that cultural identity formation may contribute to anxiety experienced particularly by adolescents of mixed heritage.  相似文献

I argue in this paper that the work of Keith Lehrer, especially in his book Self-Trust has applications to feminist ethics; specifically care ethics, which has become the leading form of normative sentimentalist ethics. I extend Lehrer??s ideas concerning reason and justification of belief beyond what he says by applying the notion of evaluation central to his account of acceptance to the need for evaluation of emotions. The inability to evaluate and attain justification of one??s emotions is an epistemic failure that leads one not to act on one??s own aspirations and desires and treat those desires as if they did not exist. I argue that this is a common condition among women in patriarchal societies because patriarchy can cause women to believe that they are not worthy of their trust concerning what they accept, specifically acceptance of their anger over their own mistreatment. As a result, many women are unable to realize the self-protective role of their anger. All of this reflects a lack of what I shall call epistemic personhood, a concept based on Lehrer??s theory concerning the keystone role of self-trust in the epistemic arch of rationality, justification and knowledge. Lastly, I use this concept of epistemic personhood to develop a care ethical account of self-respect that counters the Kantian account.  相似文献

Three experiments are reported on the development of object categorization skills during the second year of life. Experiment 1 examined whether 14- and 18-month-old infants were capable of performing categorization at the animate/inanimate (A/I) level using a sequential touching task. The 18-month-olds were significantly above chance and the 14-month-olds were also approaching above-chance significance, which is the highest level of inclusiveness ever tested in infancy. In Experiments 2 and 3, 14-month-old infants participated in a sequential touching task in which the part features of animate and inanimate objects were modified, allowing for a test of partonomic (i.e., legs and wheels) vs. taxonomic (i.e., animates and inanimates) categorization. Infants did not favor partonomic categorization, suggesting that A/I categories are not formed solely based on object parts such as legs and wheels.  相似文献
