Previous studies have described children’s acquisition of language as reflecting either a referential or an expressive style. A multivariate approach, characterizing “referentiality” and “expressivity” as partially dissociable dimensions, is advantageous because it allows children to vary along one dimension as they vary along another, allowing children to have high or low degrees of both characteristics simultaneously. The present study applies multivariate techniques to an “exploratory” sample of 87 children, all of whom were 20 months old, and by subsequently validating the exploratory phase with 56 of the original children seen one month later. Using parental reports to assess children’s multiword productions, exploratory factor analyses revealed two correlated dimensions of language style which indeed reflected referential and expressive characteristics. Confirmatory factor analyses “confirmed” these factors in the test sample. This two-dimensional model of language acquisition was superior to a unidimensional, general linguistic competence model. There is also strong short-term stability for both dimensions across the one-month period.  相似文献

A two-week training programme was provided to male and female trainees. Data were collected on each of the subject's locus of control and on each subject's perception of the degree to which their work environment would be supportive of application of skills acquired in training. The outcome variables measured for the 73 trainees (35 males, 38 females) included motivation to transfer, evaluation of the training programme, the grade achieved at the conclusion of training, self-report and immediate superior's evaluation of the use of acquired skills. Data were also collected on seniority. Hierarchical regression analysis was employed to test the effect of gender, and training-related variables on training outcomes. Controlling for the effect of seniority the data indicated that gender had an impact on motivation to transfer, and gender and seniority both had a significant effect on reaction to the course. Perceived work environment support and its interaction with seniority also accounted for a significant portion of explained variance of motivation to transfer and reactions to the course. Locus of control did not have a significant effect on four of the training outcomes but the interaction of locus of control and seniority affected the superior's evaluation of the use of skills. The results are discussed in terms of their tactical and strategic implications for the relationship between training-related variables and gender.  相似文献

Despite the high prevalence of violence in the lives of women of reproductive age, and the adverse consequences posed to pregnant women suffering from PTSD, few studies have examined violence-related trauma and PTSD among pregnant women. A structured research interview was administered to a convenience sample of 85 prenatal care women to collect information regarding their experiences of violence victimization, PTSD symptoms related to violence-related traumatic events, and whether these symptoms impaired various aspects of the women's daily functioning. Results indicated that 69% of the women experienced a violent traumatic event, with the majority of events occurring before the current pregnancy and being perpetrated by the women's intimate partners. The traumatized women evidenced high levels of PTSD symptoms during pregnancy, with 58% of the women meeting criteria for a PTSD diagnosis. Moreover, many of the women with PTSD symptoms reported that the symptoms adversely affected aspects of their daily functioning.  相似文献

Thirty children with cerebral palsy (CP) and 22 typical developing (TD) were tested with 3D-gait analysis. At turning, trunk rotation was larger in CP2 (GMFCS II) than in TD and CP1 (GMFCS I), and head flexion was larger in CP3 (GMFCS III) than TD. Maximum head and trunk flexion values during the entire trial were larger in CP3 than in the other groups, and trunk flexion was larger in CP2 than in TD. Trial time increased with GMFCS-level. Less trunk rotation than TD and CP1 reflects spatial insecurity in CP2, which in CP3 is compensated by the walker. The flexed head and trunk in CP3 and trunk in CP2 may reflect deficits in proprioception and sensation requiring visual control of the lower limbs.  相似文献

Admonitions to tell one's story in order to feel better reflect the belief that narrative is an effective emotion regulation tool. The present studies evaluate the effectiveness of narrative for regulating sadness and anger, and provide quantitative comparisons of narrative with distraction, reappraisal, and reexposure. The results for sadness (n?=?93) and anger (n?=?89) reveal that narrative is effective at down-regulating negative emotions, particularly when narratives place events in the past tense and include positive emotions. The results suggest that if people tell the “right” kind of story about their experiences, narrative reduces emotional distress linked to those experiences.  相似文献

A growing body of research suggests that a history of neglect, abuse and institutionalization can negatively affect late-adopted children’s attachment representations, and that adoptive parents can play a key role in enabling adopted children to earn secure attachments. Still, only a few studies have explored the quality of caregiver–child interaction in adoptive families. The present study aimed at verifying both the concordance of attachment in adoptive dyads (mother–children and father–children) and the relationship between attachment representations and parent–child interaction. The research involved 20 adoptive families in which the child’s arrival had occurred between 12 to 36 months before the assessment, and where children were aged between 4.5 and 8.5 years. Attachment was assessed through the Adult Attachment Interview for parents and through the Manchester Child Attachment Story Task for children. The emotional quality of parent–child interaction was assessed trough the Emotional Availability Scales. Our results pointed out the presence of a relation between attachment representations of late-adopted children and their adoptive mothers (75%, K?=?0.50, p?=?.025). In addition, we found that both insecure children and mothers showed lower levels of EA than secure ones. Some explanations are presented about why, in the early post-adoption period, child attachment patterns and dyadic emotional availability seem to be arranged on different frameworks for the two parental figures.  相似文献

I share with Poulin‐Dubois and with Sabbagh, Koenig and Kuhlmeier the conviction that more research is needed on the mechanisms supporting selective social learning in infants and children. However, my plea is more specific: for research that tests domain‐specific hypotheses about mechanism against domain‐general hypotheses derived from other fields of cognitive science. Many, but not all, of these alternative hypotheses relate to domain‐general mechanisms of attention.  相似文献

A decline in navigational abilities is a consistent feature of aging. Although many studies focused on recall of navigational information, the impact of time and type of learning on recall has received little attention. We submitted older adults and young participants to an extensive training of an ecological environment, from both route and survey perspectives. Then, we tested participants’ learning using from both route and survey perspectives. Although older adults benefit from the extensive training, they did not reach the same performance of the young participants. Despite this main effect of age, the effect of the type of learning was the same in the two groups. Congruence between type of learning and recall led to better performance in both groups. We discuss these findings in the light of cognitive models of human navigation and aging. Useful suggestions about how these findings may inform a specific cognitive intervention in older adults are also provided.  相似文献

This study was conducted to compare women’s and men’s retrospective perceptions of the mentoring they received during their training and career development in chemistry. Participants were 455 graduates (135 women) who received doctoral degrees from 11 top US chemistry programs over a 5-year period (1988–1992). In 2003, graduates completed surveys of undergraduate, graduate, post-doctoral, and initial employment experiences. In line with Social Cognitive Career Theory (Lent et al., Journal of Vocational Behavior 45:79–122, 1994), which posits that perceptions of barriers can affect career decisions, results suggest that women perceived that they received less mentoring than men at the undergraduate, graduate, and post-doctoral levels of training, likely related to gender differences in eventual career success. Possible interventions at the individual and institutional levels are discussed.  相似文献
