Magnetic resonance imaging was used to produce midsagittal images of the corpus callosum of 19 right-handed adult male and female subjects. The preliminary findings of this study indicate that significant adaptation in the anterior midbody of the corpus callosum has occurred to accommodate multiple language capacity in bilingual individuals compared to monolingual individuals. The main interpretation of this finding is that the precentral gyrus is involved in bilingual faculty adaptation assuming a role consistent with the somatotopical input to areas dedicated to the mouth, and input to association tracts connecting the premotor and supplementary motor cortices. This paper discusses possible implications to neuroscientists, second language educators, and their students. 相似文献

Professional psychology education faces many critical challenges brought about by the major changes occurring in the health care arena. This article shows that professional schools and programs have a good record of responding to these challenges and of taking proactive steps sponding to prepare their graduates for new health care roles and delivery systems. Data on admissions to psychology doctoral training programs demonstrate little support for the toral concerns raised by Donald R. Peterson (2003, this issue) about the preparation of students for graduate training in professional programs. Although quality concerns are important to investigate, such examination best resides with portant the American Psychological Association's Committee on Accreditation, which has the promotion of quality and excellence in professional psychology education and training as its major goal and responsibility. 相似文献

In this article, the authors developed several hypotheses regarding both the main and interactive effects of 2 types of team inputs on backing up behaviors in teams: (a) team composition characteristics in terms of the personality of the members of the team and (b) team task characteristics in terms of the extent to which the nature of the task is one that legitimately calls for some members of the team to back up other members of the team. Results from a study of 71 4-person teams performing a computerized tactical decision-making task suggest that the legitimacy of the need for back up has an important main effect on the extent to which team members provide assistance to and receive assistance from each other. In addition, the legitimacy of the need for back up also has important interactive effects with both the personality of the back up recipient and the personality of the back up providers on backing up behaviors in teams. 相似文献

Two studies investigated overweight in African American girls. First, African American adolescent girls (BMI was ≥ 85th percentile) and their mothers participated in focus groups addressing weight and eating. Although mothers and daughters shared some similar views on these issues, there were important discrepancies, with mothers expressing greater doubt about the potential success of a healthy weight program. The second study evaluated baseline data from 39 African American girls participating in a weight management program; mothers' reports were also analyzed. In both studies, adolescents reported significant teasing, and in the second study, teasing was inversely associated with social quality of life (β=.55, t=3.01, p=.007). Motivation to participate was positively associated with teasing (r=.50, p < .01). Self-esteem was inversely related to positive health habits (all p < .05). Mothers who viewed their daughters as having higher self-esteem were less concerned about their daughters' weight. Differences in mothers' and daughters' perceptions highlight the importance of a family approach in pediatric overweight interventions. Results provide evidence that overweight African American girls face significant weight stigmatization and suggest areas to target regarding intervention implementation.

Structural contingency theory and individual differences: examination of external and internal person-team fit 总被引:10,自引:0,他引:10

This article develops and tests a structurally based, integrated theory of person-team fit. The theory developed is an extension of structural contingency theory and considers issues of external fit simultaneously with its examination of internal fit at the team level. Results from 80 teams working on an interdependent team task indicate that divisional structures demand high levels of cognitive ability on the part of teammembers. However, the advantages of high cognitive ability in divisional structures are neutralized when there is poor external fit between the structure and the environment. Instead, emotional stability becomes a critical factor among teammembers when a divisional structure is out of alignment with its environment. Individual differences seem to play little or no role in functional structures, regardless of the degree of external fit. 相似文献

ABSTRACTChildren learning a verb may benefit from hearing it across situations . At the same time, in everyday contexts, situations in which a verb is heard will be interrupted by distracting events. Using Structural Alignment theory as a framework, Study 1 asks whether children can learn a verb when irrelevant, interleaved events are present. Two½- and 3½-year-old children saw dynamic events and were randomly assigned to one of three experimental conditions (differing in orders of events) or one of two control conditions. They extended the verbs in the experimental conditions, and not the control conditions. Three ½-year-olds were more successful than 2½-year-olds, though the younger children could extend verbs. A more difficult task is segmenting dynamic action into subevents that could be relevant for a verb (e.g., finding “chopping” in a cooking scene). In Study 2, 2½-, 3½-, and 4½-year-old children were assigned to experimental conditions in which relevant events flowed into irrelevant events (or vice versa) or to a control. Two½-year-olds failed to extend the verbs at test, differing from the older children; children in experimental conditions extended the verbs while children in the control condition did not. Altogether, these results show children can ignore irrelevant events (and subevents), and extend new verbs by 3½ years. Results are important to understand learning in everyday contexts in which verbs are heard in varied situations over time. 相似文献

This paper addresses the question of whether animals have souls and the ability to experience God after death within the limitations of their nature. Plausible explanations for the natural origin of life and for the development of subsequent complexity are increasingly being advanced by molecular biologists. Christian tradition and scholasticism teach that the human body is animated by the soul which is the agent of vital activities. This teaching is incompatible with the claim for a natural origin for life. At some stage in the evolution of chordates and cephalopods a sense of self‐awareness and an ability to distinguish between pleasure and the absence of pleasure would have arisen permitting the potential for ensoulment. The premise that evolution was gradual but ensoulment was discontinuous predicates the irrational conclusion that for one generation the parents were animals without souls and their children humans, made in the image of God, and with souls. Biological gradualism is incompatible with a sudden ensoulment dichotomy both in the evolutionary history of humans and for a maturing foetus, human or animal. Gradualism must apply to both body and soul. A Christian interpretation of physicalism, however, provides an alternative to dualism and resolves the paradoxes and difficulties relating to animals. 相似文献

The scientific study of youth entrepreneurship is truly in its infancy, with research on the development of entrepreneurship constrained by theoretical foundations that rely on static, trait-like approaches that equate entrepreneurship with stable personality characteristics. In this article, we define entrepreneurship as a fluid process that relies on the bidirectional interplay between a developing individual and his or her context. We report initial findings from the Young Entrepreneurs Study that clarify how entrepreneurial intentions and actions manifest in youth. We present quantitative analyses that examined the relations between entrepreneurial strengths and entrepreneurial activities in a sample of 3461 college students, and we describe the results of semi-structured interviews from a 48-person subset of our larger sample that explored how entrepreneurial intentions and actions manifested in our sample. We describe a mixed-method triangulation that integrates these two sets of findings, then discuss implications for future research. 相似文献

This study explores the impact megachurches have on local and extra-local congregations. Arguing that the two commonly held
theories concerning the effect of megachurches on local congregations—that they are either harmful because they undercut local
competition, or are beneficial because they increase local competition—are under-specified, we add the concept of religious
niches to an organizational ecology model to predict how megachurches will differentially impact local congregations of various
affiliation. Following new methodological directions charted by Blanchard et al. (Soc Forces 86(4):1591–1620, 2008), we test how the presence of megachurches differentially impacts congregational change rates among Catholics, Mainline Protestants,
Conservative Protestants and three disaggregated Conservative Protestant sub-groups—Evangelical, Pentecostal and Fundamentalists,
using county-level data from the 1990 and 2000 Churches and Church Membership datasets and megachurch data from the Database
of Megachurches in the US. We find support for the variable impact of megachurches on local congregations in differing niches.
For local congregations in dissimilar niches the presence of megachurches seems to be beneficial, whereas for local congregations
inhabiting similar niches the presence of megachurches seems to be harmful. In addition to the local impact of megachurches,
we find that they also have an impact upon the vitality of congregations in neighboring counties. 相似文献

This study examines the early emergence of sensory reactivity and novelty awareness and their relations to children's behaviours with peers. A total of 260 parents (242 mothers, 18 fathers) and 10 teachers of 260 children (131 male, 129 female; M = 63 months; SD = 8.80; range = 39–81) participated. Structural equation models indicate that sensory reactive children appear to be less social (i.e. prosocial and friendly), more likely to engage in solitary‐active play behaviour, and more prone to utilize instrumental aggression in peer interactions. Children scoring high on novelty awareness tend to be more social (i.e. prosocial, friendly, and control impulses), better able to appropriately and punctually comply with tasks given by teacher, less likely to engage in a number of solitary play behaviours (i.e. solitary passive and solitary active), less likely to utilize instrumental or reactive aggressive strategies, and more likely to dodge negative peer interactions by avoiding bullies. Furthermore, the associations between sensory reactivity/novelty awareness and children's behaviours differ from those of other dimensions of temperament (i.e. activity level and emotionality). This suggests that novelty awareness and sensory reactivity uniquely contribute to our overall understanding of children's temperament and its correlates. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献
