Wijeakumar, Sobanawartiny; Kumar, Aarti; Delgado Reyes, Lourdes M.; Tiwari, Madhuri; Spencer, John P. – Developmental Science, 2019
There is a growing need to understand the global impact of poverty on early brain and behavioural development, particularly with regard to key cognitive processes that emerge in early development. Although the impact of adversity on brain development can trap children in an intergenerational cycle of poverty, the massive potential for brain…

Denison, Stephanie; Xu, Fei – Developmental Science, 2010
Previous research has revealed that infants can reason correctly about single-event probabilities with small but not large set sizes (Bonatti, 2008; Teglas "et al.", 2007). The current study asks whether infants can make predictions regarding single-event probability with large set sizes using a novel procedure. Infants completed two trials: A…

Quinn, Paul C.; Doran, Matthew M.; Reiss, Jason E.; Hoffman, James E. – Developmental Science, 2010
Subordinate-level category-learning processes in infants were investigated with ERP and looking-time measures. ERPs were recorded while 6- to 7-month-olds were presented with Saint Bernard images during familiarization, followed by novel Saint Bernards interspersed with Beagles during test. In addition, infant looking times were measured during a…

Horst, Jessica S.; Scott, Emilly J.; Pollard, Jessica A. – Developmental Science, 2010
Previous research suggests that competition among the objects present during referent selection influences young children's ability to learn words in fast mapping tasks. The present study systematically explored this issue with 30-month-old children. Children first received referent selection trials with a target object and either two, three or…

Kidd, Evan; Lum, Jarrad A. G. – Developmental Science, 2008
Hartshorne and Ullman (2006 ) presented naturalistic language data from 25 children (15 boys, 10 girls) and showed that girls produced more past tense overregularization errors than did boys. In particular, girls were more likely to overregularize irregular verbs whose stems share phonological similarities with regular verbs. It was argued that…

Deater-Deckard, Kirby; Petrill, Stephen A.; Thompson, Lee A.; DeThorne, Laura S. – Developmental Science, 2005
Task persistence, measured by a composite score of independent teacher, tester and observer reports, was examined using behavioral genetic analysis. Participants included 92 monozygotic and 137 same-sex dizygotic twin pairs in Kindergarten or 1st grade (4.3 to 7.9 years old). Task persistence was widely distributed, higher among older children,…
