Associations between first-year maternal employment and mother—and youth-reported externalizing behavior at age 15 were examined paying attention to potential mediating roles of home and child care environments by 36?months, effortful control at 54?months, and externalizing behavior at 54?months and middle childhood. We used data from the NICHD Study of Early Child Care and Youth Development (n?=?922 non-Hispanic White children) which is a prospective birth cohort study that followed children from birth to age 15. Full-time first-year maternal employment was associated with higher levels of externalizing behavior at age 15 through higher maternal depressive symptoms by 36?months, lower effortful control at 54?months, and higher externalizing behavior at 54?months and middle childhood. Part-time first-year maternal employment was not associated with higher externalizing behavior at age 15.  相似文献

This investigation focused on elementary-aged (first and fourth grade) children's individual preferences for narrative and expository text and perceptions of what their same-aged peers would like to read. Preferences and perceptions of text were examined through the lenses of social constructivist and engaged reading theories. The overall purpose of this study was to examine elementary students' preferences for and perceptions about narrative and expository text. This study was a systematic replication and extension of Chapman, Filipenko, McTavish, and Shapiro's (2007) research in British Columbia with first graders. Two individually administered book preference (Open and Closed) tasks and interviews were administered to 84 students. Findings revealed gender and grade level profiles in terms of preferences, perceptions, and rationales for their book choices. As expected, both first and fourth grade boys demonstrated a strong preference for expository text, however, the fourth grade boys also showed a growing preference for narrative text as well. In contrast, both first and fourth grade girls demonstrated a strong preference for both narrative and expository text. For both boys and girls, book topic and pictures/illustrations were the two top categories that drew the children's interest and resulted in the most conversations. Results are discussed in light of implications for instruction, assessment, and future research.  相似文献

The Stroop color-naming task is one of the most widely studied tasks involving the inhibition of a prepotent response, regarded as an executive function. Several studies have examined performance on versions of the Stroop task under conditions of acute sleep deprivation. Though these studies revealed effects on Stroop performance, the results often do not differentiate between general effects of sleep deprivation on performance and effects specifically on interference in the Stroop task. To examine the effect of prolonged wakefulness on performance on the Stroop task, we studied participants in a 40-h "constant routine" protocol during which they remained awake in constant conditions and performed a Stroop color-naming task every two hours. We found that reaction time was slowest when the color and word did not match (incongruent), fastest when the color and word did match (congruent), and intermediate when participants named the color of the non-word stimulus (neutral). Performance on all three trial types degraded significantly as a function of time awake. Extended wakefulness did not significantly change the additional time needed to respond when the color and word did not match (Stroop interference), nor did it change the amount of facilitation when color and word matched. These results indicate that one night of sleep deprivation influences performance on the Stroop task by an overall increase in response time, but does not appear to impact the underlying processes of interference or facilitation. The results suggest that the degree to which an "executive function" is affected by sleep deprivation may depend on the particular executive function studied and the degree to which it is subserved by the prefrontal cortex.  相似文献

The rising use of social media, for both clinical and nonclinical purposes, obviates the need for policy to more explicitly guide physicians, and their behaviors, in this new digital environment.The current report from the AMA Council on Ethical and Judicial Affairs (CEJA) addresses a number of these issues, specifically the nature of interaction and representation between physicians and patients. However, given the nature of the focus of this report-the nonclinical use of the internet and social media-there are a number of issues that deserve attention, in particular encouraging education and addressing how to approach relationships among medical professionals of varying levels of training.  相似文献

Reichenbach’s use of ‘posits’ to defend his frequentistic theory of probability has been criticized on the grounds that it makes unfalsifiable predictions. The justice of this criticism has blinded many to Reichenbach’s second use of a posit, one that can fruitfully be applied to current debates within epistemology. We show first that Reichenbach’s alternative type of posit creates a difficulty for epistemic foundationalists, and then that its use is equivalent to a particular kind of Jeffrey conditionalization. We conclude that, under particular circumstances, Reichenbach’s approach and that of the Bayesians amount to the same thing, thereby presenting us with a new instance in which chance and credence coincide.  相似文献

Using data from the National Education Longitudinal Study, the authors examined relations between educational, civic, and occupational success in young adulthood and the duration and intensity of participation in organized activities during high school. They also examined these relations as a function of sponsorship (i.e., school- vs. community-sponsored organized activities). They found that youths who participated in organized activities for 2 years demonstrated more favorable educational and civic outcomes in young adulthood than those who participated for 1 year. More intensive participation was also associated with greater educational, civic, and occupational success in young adulthood--particularly among youths who participated in activities for 2 years. Educational attainment often mediated the relations between temporal measures of participation and young adult civic and occupational outcomes. With the exception of analyses examining occupational success, findings varied little as a function of sponsorship. Of note, analyses revealed that both temporal measures of participation were positively associated with young adult outcomes as many as 8 years after high school.  相似文献

In this study, the authors examined whether parent-child conflict during the middle childhood years varied among families characterized as having different cultural traditions regarding issues of respect for parental authority and parenting practices. The sample included 133 African American, European American, and Latina girls (M age = 8.41 years) and their mothers. African American and Latina girls showed significantly more respect for parental authority than did European American girls. Furthermore, African American and Latina mothers reported significantly more intense arguments when respect was low than did European American mothers. Higher levels of discipline and better communication by mothers were both associated with reports of lower frequency of conflict; ethnicity did not moderate this association. Thus, respect for authority was most salient to group differences in conflict.  相似文献

The Buddhist practice of mindfulness is being used more often both to help clients and to facilitate counselor effectiveness. A growing body of research supports these uses of mindfulness. Most authors also emphasize that those who teach mindfulness must also apply it themselves. However, little is known about how counselors and counselor educators incorporate mindfulness into their personal and professional lives. The current study used semistructured interviews to elicit such information from 6 counselors and counselor educators. A constant comparative method was used to analyze the data and synthesize themes. Emergent themes included practices used to cultivate mindfulness and the results of mindfulness practices.  相似文献

The present study examined whether there are ethnic differences in perceptions of campus climate, social support, and academic efficacy among community college students, and whether student perceptions were associated with academic success. A total of 475 community college students completed a questionnaire that measured students’ perceptions of cultural congruity, college environment, mentoring, peer social life and academic self efficacy. Ethnic differences were observed, as African American and Caucasian students reported higher levels of cultural congruity than Asian students and higher academic self efficacy than Asian and Latino students. There were also ethnic differences in the relationship between the students’ perceptions and GPA. Cultural congruity and efficacy correlated with GPA among Latino students, academic efficacy correlated with GPA among Asian students, peer social support and college environment correlated with GPA among Caucasians, however, none of the perceptions scales correlated with GPA among African American students. The lack of relationship between academic efficacy and GPA among African American and Caucasians students is discussed.  相似文献

We propose that managers have norms (standards of appropriate behavior) for resolving conflict, that these norms are culturally based, and that they explain cultural differences in conflict management outcomes. We confirm that the traditionally American norms of discussing parties' interests and synthesizing multiple issues were exhibited more strongly by American managers than by their Hong Kong Chinese counterparts. In addition, we confirm that the traditionally Chinese norms of concern for collective interests and concern for authority appeared more strongly among Hong Kong Chinese managers than among their American counterparts. American managers were more likely than Hong Kong Chinese managers, to resolve a greater number of issues and reach more integrative outcomes, while Hong Kong Chinese managers were more likely to involve higher management in conflict resolution. Culture had a significant effect on whether parties selected an integrative outcome rather than an outcome that involved distribution, compromise, higher management, or no resolution at all. Conflict norms explained the cultural differences that existed between reaching an integrative outcome and reaching an outcome involving distribution, compromise, or higher management; however, conflict norms did not fully explain the cultural differences that existed between reaching an integrative outcome and reaching no resolution.  相似文献
