Studies have shown that child development is negatively affected by prenatal depression. A dysregulated hypothalamic-pituitary-adrenal axis in the pregnant woman, passed to the fetus, is one discussed key mechanism. Studies, investigating primary-school age children, have found effects on antisocial behavior. Effects on internalizing symptoms were not found, but the analysis did not distinguish between anxiety and depression symptoms. Additionally, until now, no objective test data operationalizing social-emotional competencies have been included. The present study examined: 1.Whether the effects on child externalizing symptoms could be replicated; 2. If there are specific effects on child internalizing symptoms, separated for anxiety and depression; and 3. Are child clinical symptoms reflected in reductions in social-emotional competencies. A sample of 61 prenatally depressed and 143 prenatally not-depressed women and their 6–9 year old children were compared, controlling for key confounders in both the perinatal period and in middle childhood. Children of prenatally depressed mothers had more antisocial behavior and depression symptoms reported by their mothers. The prediction of antisocial behavior scores tended to be more significant for boys than for girls. Child anxiety symptoms were primarily explained by current maternal depressive symptoms. Children of prenatally depressed mothers also showed a reduction in social-emotional competencies, specifically regarding the ability to interpret complex social situations. This study showed that, even in a non-clinical sample, there are distinct effects of prenatal depression on child externalizing and internalizing symptoms which are accompanied by reductions in specific social-emotional competencies. These results emphasize that treatment for depressed pregnant women and/or early support for affected families is worthwhile. Additional work is required to identify the underlying biological mechanisms.  相似文献

Callous-unemotional traits (CU) are thought to be the developmental precursor to adult psychopathy, and identify antisocial youth at risk for persistent, aggressive conduct problems. Accumulating research supports the importance of parenting factors in the development of CU traits. The overlapping but distinct constructs, parental neglect and low warmth, are both associated with CU/psychopathic traits; however, research is yet to examine the relative contribution of these constructs. The purpose of the present study was to examine the unique contributions of parental neglect and low warmth to CU traits among 227 incarcerated male juvenile offenders (M?=?15.73, SD?=?1.27 years). Results indicated that low levels of maternal warmth were more strongly associated with CU traits than emotional and physical neglect. Maternal warmth also significantly mediated the association between emotional neglect and CU traits. Findings from this cross-sectional study suggest that parental neglect influences CU traits at least partly through experiences with unresponsive and emotionally “cold” parenting. The findings also support a movement within the field towards addressing parental warmth as a treatment target for antisocial youth with CU traits.  相似文献

Abstract

The growing body of evidence in education reveals that ‘spirituality’ as an aspect of learning is largely overlooked in government schools in Australia and consequently, there is a paucity of research investigating whether young people consider spirituality to be an important and worthwhile component of their educational experience. This paper will report on some findings of a PhD study which investigates the spiritual lived experiences of secondary school students. As an interdisciplinary approach to spirituality for adolescents, this paper represents the different ways spirituality is understood across the disciplines and whether young people view themselves to be ‘spiritual’. In sharing some of the student narratives, this paper will explore what spirituality means in the context of young peoples’ everyday lives. It will also address how schools can play a central role in students’ quest for a sense of meaning; and the important role of teachers in this process will also be explored.  相似文献

We conducted a comprehensive analysis of assortative mating (i.e., the similarity between wives and husbands on a given characteristic) in a newlywed sample. These newlyweds showed (a) strong similarity in age, religiousness, and political orientation; (b) moderate similarity in education and verbal intelligence; (c) modest similarity in values; and (d) little similarity in matrix reasoning, self- and spouse-rated personality, emotional experience and expression, and attachment. Further analyses established that similarity was not simply due to background variables such as age and education and reflected initial assortment (i.e., similarity at the time of marriage) rather than convergence (i.e., increasing similarity with time). Finally, marital satisfaction primarily was a function of the rater's own traits and showed little relation to spousal similarity.  相似文献

The issue of regular-irregular past tense formation was examined in a cross-modal lexical decision task in Modern Greek, a language where the orthographic and phonological overlap between present and past tense stems is the same for both regular and irregular verbs. The experiment described here is a follow-up study of previous visual lexical decision experiments (Tsapkini, Kehayia, & Harema, 2002) that also addressed the regular-irregular distinction in Greek. In the present experiment, we investigated the effect of input modality in lexical processing and compared different types of regular and irregular verbs. In contrast to our previous intra-modal (visual-visual) priming experiments, in this cross-modal (auditory-visual) priming study, we found that regular verbs with an orthographically salient morphemic aspectual marker elicited the same facilitation as those without an orthographically salient marker. However, irregular verbs did not exhibit a different priming pattern with respect to modality. We interpret these results in the framework of a two-level lexical processing approach with modality-specific access representations at a surface level and modality-independent morphemic representations at a deeper level.  相似文献

This study adopted a perspective of the individual to define domains of everyday life for the analysis of clinically meaningful change. The purpose was to compare the clinical significance of two interventions for patients with musculoskeletal pain, applying an idiographic outcome measure, The Patient Goal Priority Questionnaire, in combination with the Jacobson and Truax methodology [(1991). Clinical significance: A statistical approach to defining meaningful change in psychotherapy research. Journal of Consulting and Clinical Psychology, 67 (3), 300-307] for determination of clinical significance. The concurrent validity of the outcome variables behavioral performance, satisfaction with behavioral performance, and fulfilled pre-treatment expectations was also studied. Eighty-two patients, randomized to either individually tailored behavioral medicine treatment (experimental group) or physical exercise therapy (control group) were evaluated at baseline and 3 months post-treatment regarding behavioral treatment goals. The experimental intervention had high impact on participants' performance of their highest ranked everyday life activities, and resulted in larger proportions of clinically significant outcomes compared with controls. The concurrent validity of the outcomes was high for those reporting clinically significant changes, but more generally, there was a moderate agreement across outcome categories. The individual should be the unit for analyses of clinical significance to enhance the ecological validity of the construct. Further development of idiographic outcome measures is necessary, as is the inclusion in pain intervention research.  相似文献

Numerical order and quantity processing in number comparison   总被引:4,自引:0,他引:4

We investigated processing of numerical order information and its relation to mechanisms of numerical quantity processing. In two experiments, performance on a quantity-comparison task (e.g. 2 5; which is larger?) was compared with performance on a relative-order judgment task (e.g. 2 5; ascending or descending order?). The comparison task consistently produced the standard distance effect (faster judgments for far relative to close number pairs), but the distance effect was smaller for ascending (e.g. 2 5) compared to descending pairs (e.g. 5 2). The order task produced a pair-order effect (faster judgments for ascending pairs) and a reverse distance effect for consecutive pairs in ascending order. The reverse effect implies an order-specific process, such as serial search or direct recognition of order for successive numbers. Thus, numerical quantity and order judgments recruited different cognitive mechanisms. Nonetheless, the reduced distance effect for ascending pairs in the quantity task implies involvement of order-related processes in magnitude comparison. Accordingly, distance effects in the quantity-comparison task are not necessarily a process-pure measure of magnitude representation.  相似文献

This research examined whether the tendency for girls to outperform boys in the classroom is due to differences in how girls and boys approach schoolwork. In 5th grade and then again in 7th grade, children (N=518) reported on how they approach schoolwork (i.e., achievement goals and classroom behavior), their learning strategies, and their self-efficacy in math; math grades and achievement test scores were also collected. Girls were more likely than boys to hold mastery over performance goals and to refrain from disruptive classroom behavior, which predicted girls' greater effortful learning over time. The sex difference in learning strategies accounted for girls' edge over boys in terms of grades. Girls did not do better on achievement tests, possibly because self-efficacy, for which there was also no sex difference, was the central predictor of performance on achievement tests.  相似文献

There is much evidence that parents' perceptions of children's competence affect the development of children's academic functioning. In the current research, the possibility that this is moderated by parents' theories about the stability of competence was examined. In a 2-wave, 1-year study of 126 children (9 to 12 years old) and their mothers, children's academic functioning (i.e., grades, perceptions of competence, attributions for performance, and mastery orientation) and affective functioning (i.e., self-esteem and depressive symptoms) were examined. Among mothers with relatively high entity theories, their perceptions acted as self-fulfilling prophecies foreshadowing children's academic and affective functioning over time. However, among mothers with relatively low entity theories, mothers' perceptions did not predict children's academic and affective functioning.  相似文献
