This study investigates the impact of evidentiality on source monitoring and the impact of source monitoring on false belief understanding (FBU), while controlling for short-term memory, age, gender, and receptive vocabulary. One hundred (50 girls) monolingual 3- and 4-year-olds from Turkey and the UK participated in the study in 2019. In Turkish,…

This study employs the Specificity Principle to examine the relative impacts of external (input quantity at home and at school, number of books and reading frequency at home, teachers' degree and experience, language usage, socioeconomic status) and internal factors (children's working memory, nonverbal intelligence, learning-related…

This study examined the relation of 3-year core information-processing abilities to lexical growth and development. The core abilities covered four domains--memory, representational competence (cross-modal transfer), processing speed, and attention. Lexical proficiency was assessed at 3 and 13 years with the Peabody Picture Vocabulary Test (PPVT)…

Using data from children in South Korea (N = 145, M[subscript age] = 6.08), it was determined how low-level language and cognitive skills (vocabulary, syntactic knowledge, and working memory) and high-level cognitive skills (comprehension monitoring and theory of mind [ToM]) are related to listening comprehension and whether listening…

The present study explored the environmental and genetic etiologies of the longitudinal relations between prereading skills and reading and spelling. Twin pairs (n = 489) were assessed before kindergarten (M = 4.9 years), post-first grade (M = 7.4 years), and post-fourth grade (M = 10.4 years). Genetic influences on five prereading skills (print…

Assessed 2-year olds' ability to use semantic context to infer meanings of novel nouns and to retain those meanings. Found that children learned majority of novel words; however, they occasionally failed to choose the correct corresponding picture for a novel noun even when they understood the verb; also found a significant retention of newly…

Used a modification of Akhtar, Carpenter, and Tomasello's (1996) task involving interpretation of novel nouns to test whether 18- to 28-month-olds' smart word learning derived from general attention and memory processes rather than knowledge about the communicative intents of others. Findings similar to those of Akhtar and colleagues suggest that…

Examined word retrieval in 14- to 24-month-olds. Found that children with limited productive vocabularies were less likely to produce labels of hidden objects than children with larger vocabularies, even though all could name them and did well when asked to find them. Pictorial cues facilitated word retrieval. Naming errors peaked among children…
