Yuewen Zhang; Zhenhong Wang – Developmental Science, 2024
Intra-individual response time variability (IIRTV) during cognitive performance is increasingly recognized as an important indicator of attentional control (AC) and related brain region function. However, what determinants contribute to preschoolers' IIRTV received little attention. The present study explored the interaction of dopaminergic…

Weiss, Staci Meredith; Marshall, Peter J. – Developmental Science, 2023
The development of the ability to anticipate--as manifested by preparatory actions and neural activation related to the expectation of an upcoming stimulus--may play a key role in the ontogeny of cognitive skills more broadly. This preregistered study examined anticipatory brain potentials and behavioral responses (reaction time; RT) to…

Delalande, Lisa; Moyon, Marine; Tissier, Cloélia; Dorriere, Valérie; Guillois, Bernard; Mevell, Katel; Charron, Sylvain; Salvia, Emilie; Poirel, Nicolas; Vidal, Julie; Lion, Stéphanie; Oppenheim, Catherine; Houdé, Olivier; Cachia, Arnaud; Borst, Grégoire – Developmental Science, 2020
A number of training interventions have been designed to improve executive functions and inhibitory control (IC) across the lifespan. Surprisingly, no study has investigated the structural neuroplasticity induced by IC training from childhood to late adolescence, a developmental period characterized by IC efficiency improvement and protracted…

Nash, Hannah M.; Gooch, Debbie; Hulme, Charles; Mahajan, Yatin; McArthur, Genevieve; Steinmetzger, Kurt; Snowling, Margaret J. – Developmental Science, 2017
The "automatic letter-sound integration hypothesis" (Blomert, [Blomert, L., 2011]) proposes that dyslexia results from a failure to fully integrate letters and speech sounds into automated audio-visual objects. We tested this hypothesis in a sample of English-speaking children with dyslexic difficulties (N = 13) and samples of…

Czernochowski, Daniela; Mecklinger, Axel; Johansson, Mikael – Developmental Science, 2009
We examined developmental aspects of the ability to monitor the temporal context of an item's previous occurrence while event-related potentials (ERPs) were recorded. In a continuous recognition task, children between 10 and 12 years and young adults watched a stream of pictures repeated with a lag of 10-15 intervening items and indicated…

Richards, John E. – Developmental Science, 2005
This study used cortical source analysis to locate potential cortical sources of event-related potentials (ERPs) during covert orienting in infants aged 14 and 20 weeks. The infants were tested in a spatial cueing procedure. The reaction time to localize the target showed response facilitation for valid trials relative to invalid or neutral…

Casey, B. J.; Davidson, Matthew C.; Hara, Yuko; Thomas, Kathleen M.; Martinez, Antigona; Galvan, Adriana; Halperin, Jeffrey M.; Rodriguez-Aranda, Claudia E.; Tottenham, Nim – Developmental Science, 2004
This study examined the cognitive and neural development of attention switching using a simple forced-choice attention task and functional magnetic resonance imaging. Fourteen children and adults made discriminations among stimuli based on either shape or color. Performance on these trials was compared to performance during blocked trials…

Dick, Frederic; Wulfeck, Beverly; Krupa-Kwiatkowski, Magda; Bates, Elizabeth – Developmental Science, 2004
This study compared sentence comprehension skills in typically developing children 5-17 years of age, children with language impairment (LI) and children with focal brain injuries (FL) acquired in the pre/perinatal period. Participants were asked to process sentences "on-line", choosing the agent in sentences that varied in syntactic complexity…
