The effects of language on symbolic functioning were examined using the boxes task, a new symbolic understanding task based on DeLoache's model task. Children (N = 32; ages 2;4–3;8) observed an object being hidden in a stack of four boxes and were then asked to retrieve a similar object in the same location from a set of four target boxes. Each box was identified with a different object sitting on a small ledge in front of it. Language use was manipulated by providing linguistic scaffolding (naming vs. standard) and by using objects to identify the boxes whose names were either known or unknown to the children (familiar vs. language control). Home language environment (monolingual vs. bilingual) and verbal age (measured via the Peabody Picture Vocabulary Test-Third Edition) were also examined. Main effects were found for type of object (with familiar objects yielding better performance), home linguistic environment (with bilingualism resulting in better performance), and verbal age. There was also a verbal age × linguistic scaffolds interaction: Verbal age was related to correct retrievals only in the naming condition. These results provide further evidence that language mediates children's symbolic development and indicate that the new boxes task is an effective way of evaluating young children's symbolic competencies. 相似文献
The objective of this study was to examine, by gender, whether emotional intelligence (EI), peer social support, and/or family social support partially mediated the influence of verbal IQ on Grade 10 grade point average (GPA) for 192 students (96 male, 96 female). For male students, EI and peer social support predicted GPA and EI mediated the association between verbal IQ and GPA. For female students, EI, peer social support, and family support predicted GPA but did not mediate the association between verbal IQ and GPA. This study further examined whether subscales of EI (intrapersonal, interpersonal, adaptability, and stress management abilities), peer social support and family social support (emotional, socialising, practical, financial, and advice) added to the prediction of GPA after verbal IQ, gender, and socioeconomic status were controlled. Adaptability, stress management and practical family social support each added to the explanation of variability. None of the peer social support subscales predicted additional variance in GPA. 相似文献
The present investigation examined pain-related anxiety in regard to marijuana use motives among a sample of young adult marijuana users (N = 180; 45% women; M(age) = 21.11 years, SD = 6.41). Hierarchical multiple regression analyses were used to determine the relations between pain-related anxiety and marijuana use motives. After controlling for current marijuana use frequency (past 30 days), daily cigarette smoking rate, current rate of alcohol consumption, level of bodily pain (current), and other marijuana use motives, pain-related anxiety was significantly and uniquely associated with coping and conformity motives for marijuana use. Pain-related anxiety was not significantly related to other marijuana use motives. These results offer novel empirical insight pertaining to a relation between pain-related anxiety and coping as well as conformity motives for marijuana use among active users. 相似文献
A contentious issue in contemporary psycholinguistics is whether bilingualism enhances executive functions. Here, we report a meta-analysis of 80 studies (253 effect sizes) comparing performance of monolinguals and bilinguals on non-verbal interference-control tasks, while examining potential moderators of effects on two dependent variables (DVs): global reaction time (RT) and interference cost. We used a multiverse approach to determine how robust conclusions were to several dataset construction and analysis decisions. In our “preferred” analysis, using a broad definition of bilinguals and standard versions of interference-control tasks, there was a very small but significant bilingual advantage for global RT (g =.13), which became non-significant once corrected for publication bias. For interference cost, there was a very small but significant bilingual advantage (g =.11). Effects were not significantly moderated by task or participant age, but were moderated by an interaction between age of second language acquisition (AoA) and the DV. Unexpectedly, larger effect sizes for interference cost were observed for studies involving bilinguals with late as opposed to early AoA. The multiverse analysis produced results largely consistent with the preferred analysis, confirming our conclusion that evidence for a bilingual advantage on interference-control tasks is weak.
Over the past 20 years, systemically guided approaches to understanding early family processes have helped to provide greater clarity concerning the interplay among individual, dyadic, and family level processes. Parental depression, marital functioning, and child adjustment in particular appear to be reliable predictors of coparental and family level functioning. Indeed, cohesion at the level of the family group covaries in theoretically meaningful ways with these indicators of individual and dyadic adjustment. In this study, two collaborating research groups (one in Switzerland, the second in the United States) partnered to examine whether similar patterns of relationships exist among individual and marital adjustment and coparenting processes in families of 4‐year‐old children. Using similar constructs but disparate and occasionally dissimilar measures, both groups measured parent‐reported depression, marital satisfaction, and child behavior problems. Coparenting cooperation and warmth were observed during family interactions. Despite differences between samples and evaluation tools, similar results were found for the Swiss and U.S. samples. A model with depression, marital satisfaction, and child symptoms as predictors of a latent factor of observed coparenting cooperation and warmth showed good fit to data in both samples, suggesting the model was relevant for each. Parameter estimation showed that higher coparenting cooperation and warmth was predicted by lower maternal depression and higher child internalizing symptoms. The common significant effects despite differences in assessment paradigms and instrumentation are of substantive interest. Future directions pertinent to the coparenting questions addressed in this research are discussed. 相似文献
This article analyzes the topic of leadership from an evolutionary perspective and proposes three conclusions that are not part of mainstream theory. First, leading and following are strategies that evolved for solving social coordination problems in ancestral environments, including in particular the problems of group movement, intragroup peacekeeping, and intergroup competition. Second, the relationship between leaders and followers is inherently ambivalent because of the potential for exploitation of followers by leaders. Third, modern organizational structures are sometimes inconsistent with aspects of our evolved leadership psychology, which might explain the alienation and frustration of many citizens and employees. The authors draw several implications of this evolutionary analysis for leadership theory, research, and practice. 相似文献
The critical resources furnished bydeconstruction have more than occasionally beenturned with negative effect on traditional andmore recent conceptions of liberal learning,including the reaffirmation of the humanitiesassociated with philosophical hermeneutics. Thefirst two sections of the paper review thecontrasting and mutually opposed stancestowards learning represented by earlyformulations of deconstruction and ofhermeneutics. An exploration is thenundertaken in the later sections ofdevelopments that have taken place in bothdeconstruction and hermeneutics since theDerrida-Gadamer encounter in Paris in 1981.While not in any sense assimilatinghermeneutics to deconstruction or vice versa,this exploration identifies significant shiftsin later formulations of both which provide amore inclusive context for understandinglearning as a human undertaking, including theidentification of tensions that are morepromising than negative. 相似文献
