Phonological priming and cohort effects in toddlers

Adult word recognition is influenced by prior exposure to phonologically or semantically related words (cup primes cat or plate) compared to unrelated words (door), suggesting that words are organised in the adult lexicon based on their phonological and semantic properties and that word recognition implicates not just the heard word, but also related words. We investigate the phonological organisation of the toddler lexicon with two experiments using a picture priming technique. Twenty-four month olds showed inhibition of target recognition in related primed trials compared to unrelated primed trials (Experiment 1) and also in related primed trials compared to unprimed trials (Experiment 2). Further analysis of children’s responding found that this inhibition effect was modulated by the cohort and neighbourhood size of the words tested. Overall, the results indicate a lexical basis for the reported effects and suggest that the phonological properties provide an organisational basis for words in the toddler lexicon.     

Neighbourhood,school and family determinants of children's aspirations in primary school

Aspirations can be important for young children as well as adolescents. However, there is little research on the determinants of aspirations in young children. We carried out this study to investigate the early contextual (neighbourhood, school and family) determinants of occupational aspirations in primary school children. Our sample comprised children from the Millennium Cohort Study who lived in England in the beginning of our study period (n = 10,086; 5,126 boys). Occupational aspirations were measured at age 7 years, while their contextual determinants were measured in the previous data sweeps, at ages 3 and 5 years. We fitted structural equation models to test the role of family and neighbourhood socio-economic status (SES) and child ethnicity in predicting aspirations both directly and via their associations with parental involvement, household chaos, school-level achievement and child cognitive ability. We found that the only significant determinants of aspirations at age 7 years were family SES and ethnicity, and only in boys. Family SES and ethnicity were also related to parental involvement, household chaos, cognitive ability and school-level achievement, but none of these factors predicted aspirations. Supplementary analysis showed that family SES was a particularly powerful determinant of the aspirations of white compared to non-white boys.
