Timed picture naming was compared in seven languages that vary along dimensions known to affect lexical access. Analyses over items focused on factors that determine cross-language universals and cross-language disparities. With regard to universals, number of alternative names had large effects on reaction time within and across languages after target-name agreement was controlled, suggesting inhibitory effects from lexical competitors. For all the languages, word frequency and goodness of depiction had large effects, but objective picture complexity did not. Effects of word structure variables (length, syllable structure, compounding, and initial frication) varied markedly over languages. Strong cross-language correlations were found in naming latencies, frequency, and length. Other-language frequency effects were observed (e.g., Chinese frequencies predicting Spanish reaction times) even after within-language effects were controlled (e.g., Spanish frequencies predicting Spanish reaction times). These surprising cross-language correlations challenge widely held assumptions about the lexical locus of length and frequency effects, suggesting instead that they may (at least in part) reflect familiarity and accessibility at a conceptual level that is shared over languages.  相似文献

This study examines the cross-cultural generality of Hering's (1878/1964) color-opponent theory of color appearance. English-speaking and Somali-speaking observers performed variants of two paradigms classically used to study color-opponency. First, both groups identified similar red, green, blue, and yellow unique hues. Second, 25 English-speaking and 34 Somali-speaking observers decomposed the colors present in 135 Munsell color samples into their component Hering elemental sensations—red,green,blue, yellow, white, and black—or else responded “no term.” Both groups responded no term for many samples, notably purples. Somali terms for yellow were often used to name colors all around the color circle, including colors that are bluish according to Hering's theory. Four Somali Grue speakers named both green and blue elicitation samples by their term for green. However, that term did not name the union of all samples called blue or green by English speakers. A similar pattern was found among three Somali Achromatic speakers, who called the blue elicitation sample black or white. Thus, color decomposition by these Somali-speaking observers suggests a lexically influenced re-dimensionalization of color appearance space, rather than a simple reduction of the one proposed by Hering. Even some Somali Green-Blue speakers, whose data were otherwise similar to English, showed similar trends in yellow and blue usage. World Color Survey data mirror these results. These within- and cross-cultural violations of Hering's theory do not challenge the long-standing view that universal sensory processes mediate color appearance. However, they do demonstrate an important contribution of language in the human understanding of color.  相似文献

This paper describes the process of a community–academic partnership to navigate implementation challenges for a school‐based service model led by paraprofessionals to promote positive parenting in high poverty urban communities. We describe the process by which we (a) identified implementation challenges, (b) sustained a university–community collaboration to redesign the paraprofessional service model, and (c) assessed the feasibility of the new model involving four social service agencies in 16 schools with over 600 families. The structure and process of the collaboration and refinement are described with attention to who was best positioned to engage in the collaboration and how the partnership worked to balance scientific rigor with responsiveness to paraprofessional workforce strengths. Feasibility data indicated that the revised model was successfully implemented by paraprofessional staff; 92.2% of possible staff monthly reports were completed and discussion of key goals was incorporated into 94.2% of interactions. Continual monitoring provided critical feedback from stakeholders as we drew on and interpreted these various sources of information to build and refine the service model. We suggest that these processes are critical steps to bridge the research‐to‐practice gap, by promoting practices that are aligned with the needs of children and families, and the staff who serve them.  相似文献

Employee silence is a costly but omnipresent phenomenon in modern organisations. In this study, we focus on two forms of silence: defensive silence based on fear and acquiescent silence based on resignation. Given the power imbalance in supervisor–subordinate relationships, we hypothesise that abusive supervision is an antecedent of subordinates’ defensive silence and that a subordinate’s power distance orientation affects acquiescent silence. We investigate the interaction effects of abusive supervision and power distance orientation on these two types of silence. Perceived organisational politics may also aggravate such interactive effects. Based on data collected from 159 junior employees in China in two periods, we find that abusive supervision is associated with employee defensive silence and moderates high-power-distance employees’ tendency to engage in acquiescent silence. When perceiving high politics in the organisation, high-power-distance employees are more sensitive to abusive supervision and engage in more defensive silence. A highly political organisational context also accentuates abusive supervision’s moderating effect on the relation between employees’ power distance orientation and acquiescent silence. We conclude with theoretical and practical implications for the silence literature.  相似文献

Exposure to community violence is thought to create risk for the social and emotional development of children, including those children living in low‐income, conflict‐affected countries. In the absence of other types of community resources, schools may be one of the few community resources that can help buffer children from the negative effects of community violence exposure. We sampled 8,300 students ranging in age from 6–18 years in 123 schools from the eastern Democratic Republic of Congo to examine whether and how two distinct dimensions of positive school climate can protect two key features of children's social‐emotional development in the presence of community violence. Multi‐level models tested the hypothesis that students’ perceptions of a positive school climate moderated the relation between community violence and self‐reported mental health problems and peer victimization. Findings support the hypothesis. Specifically, a positive school climate protected against mental health problems and peer victimization in the presence of high community violence. Students who experienced high community violence and a negative school climate generally demonstrated the worst development. We find complex interactions between the dimensions of school climate and exposure to violence on student social‐emotional development that highlight the salience of children's contexts for developmental studies in low‐income countries. We use dynamic developmental systems theory and differential impact to discuss the dual potential of schools as a buffer against the effects of violence or as a source of compounded risk.  相似文献
