Data from a nationally representative sample from Turkey (N = 1,017) were used to investigate the environmental factors that support the receptive vocabulary of 3-year-old children who differ in their developmental risk due to family low economic status and elevated maternal depressive symptoms. Children's vocabulary knowledge was strongly associated with language stimulation and learning materials in all families regardless of risk status. Maternal warmth and responsiveness supported vocabulary competence in families of low economic status only when maternal depressive symptoms were low. In families with the highest levels of risk, that is, with depression and economic distress jointly present, support by the extended family and neighbors for caring for the child protected children's vocabulary development against these adverse conditions. The empirical evidence on the positive contribution of extrafamilial support to young children's receptive vocabulary under adverse conditions allows an expansion of our current theorizing about influences on language development.

The authors explore the impact of geographical proximity of environmental problems on environmental concern and willingness to pay (WTP) for environmental improvement, with emphasis on the relevance of Inglehart’s postmaterialism thesis on this inquiry. A questionnaire was administered to 1,565 respondents in Istanbul. The Contingent Valuation Method was used to measure WTP. Sea pollution in Istanbul (local issue), soil erosion in Turkey (national issue), and ozone depletion (global issue) were issues chosen for valuation. The sample was separated into three subsamples, with each being presented with only one issue. Individuals distinguish between local and global environmental concern. People with materialist values rather than postmaterialist values exhibit more concern for local environmental problems. However, postmaterialist values determine WTP for improvement in both the local and the global environmental problems. Distinguishing among concern for environmental issues, which are differentiated on the basis of geographical proximity, has relevance for the ongoing postmaterialist values debate.
