Cognitive tasks are seldom evaluated on their ability to provide valid and reliable measurements of the construct they intend to measure. This scarcity of psychometric evaluations makes it challenging to evaluate replications of experimental effects and to relate performance in cognitive tasks to other constructs of interest. In developmental…

Previous research showed that short-term second language training modulates children's brain responses to language processing. However, little is known about whether short-term training from language-immersion apps would have the same effect on young children's neural processing of a newly learnt language. We examined the auditory event-related…

The current study examined the inter-brain coherence (IBC) between 34 dyads of fathers and infants 7-9 months of age using functional near-infrared spectroscopy (fNIRS). We specifically focused on father-infant IBC to broaden the empirical base beyond the mother-infant connections, as the former has received limited attention. There were three…

Relying on self-report to understand how children solve cognitive tasks has limitations, particularly with young children. Recent advances in eye-tracking technology allow researchers to leverage this tool to measure young children's strategies for solving cognitive tasks. The current study focuses on young children's mental rotation ability given…
