All accounts of language acquisition agree that, by around age 4, children’s knowledge of grammatical constructions is abstract, rather than tied solely to individual lexical items. The aim of the present research was to investigate, focusing on the passive, whether children’s and adults’ performance is additionally semantically constrained, varying according to the distance between the semantics of the verb and those of the construction. In a forced-choice pointing study (Experiment 1), both 4- to 6-year olds (N = 60) and adults (N = 60) showed support for the prediction of this semantic construction prototype account of an interaction such that the observed disadvantage for passives as compared to actives (i.e., fewer correct points/longer reaction time) was greater for experiencer-theme verbs than for agent-patient and theme-experiencer verbs (e.g., Bob was seen/hit/frightened by Wendy). Similarly, in a production/priming study (Experiment 2), both 4- to 6-year olds (N = 60) and adults (N = 60) produced fewer passives for experiencer-theme verbs than for agent-patient/theme-experiencer verbs. We conclude that these findings are difficult to explain under accounts based on the notion of A(rgument) movement or of a monostratal, semantics-free, level of syntax, and instead necessitate some form of semantic construction prototype account.  相似文献

Human immunodeficiency virus (HIV) continues to be a prominent health and social justice issue, especially for African American communities in the Southern United States. Gender role norms, specifically within faith-based communities in the South, pose challenges to empowering women to make safer sexual health decisions. To explore perceptions of gender norms and sexual health, 42 qualitative interviews were gathered from female members of 16 predominantly African American churches in Atlanta, GA. Constructs from the theory of gender and power and the social ecological model were used to guide coding and analysis. Participants discussed their experiences with gender norms and gender-based power differentials at the institutional (i.e., church), familial, and interpersonal (i.e., intimate relationship) levels. Because of the attitudes and beliefs held by their religious communities and families, many participants recalled struggling to assert themselves in sexual relationships and recalled engaging in risky and unwanted sexual behavior, especially during their young adult years. However, as the participants matured, they worked to overturn traditional gender norms, empowering both their children and women in their religious communities to make healthy, autonomous sexual decisions. Moving forward, participants want their churches and members of their faith communities to play an active role in the empowerment of African American women and provide them with the confidence and education necessary to negotiate sexual decisions with their partners.

This study identified mediators of a school-based nutrition intervention for 4th graders and their parents. Nine variables were tested for satisfying 4 conclusions necessary to establish mediation of intervention effects on changes in fruit and vegetable consumption (FVC) in 4th graders (N = 1,676). FVC was measured in children by the use of 24-hr dietary recalls. Mediators were assessed by the use of questionnaires completed by children and parents. All 4 conclusions were met for positive outcome expectancies. Knowledge, self-efficacy, and parent consumption satisfied the first 3 conclusions for mediation but the mediating effects were not statistically significant (Conclusion 4). Future mediational analyses and the creation of a national database of mediators are crucial for increasing strength and efficiency of school-based nutrition programs.  相似文献
