Timed picture naming in seven languages

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.     

Risk or resource: Does school climate moderate the influence of community violence on children’s social‐emotional development in the Democratic Republic of Congo?

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.
