Mumford, Katherine H.; Aussems, Suzanne; Kita, Sotaro – Developmental Science, 2023
Previous research has shown a strong positive association between right-handed gesturing and vocabulary development. However, the causal nature of this relationship remains unclear. In the current study, we tested whether gesturing with the right hand enhances linguistic processing in the left hemisphere, which is contralateral to the right hand.…

Takarae, Yukari; Zanesco, Anthony; Keehn, Brandon; Chukoskie, Leanne; Müller, Ralph-Axel; Townsend, Jeanne – Developmental Science, 2022
EEG microstates represent transient electrocortical events that reflect synchronized activities of large-scale networks, which allows investigations of brain dynamics with sub-second resolution. We recorded resting EEG from 38 children and adolescents with Autism Spectrum Development (ASD) and 48 age, IQ, sex, and handedness-matched typically…

Vauclair, Jacques; Imbault, Juliette – Developmental Science, 2009
The aim of this study was to measure the pattern of hand preferences for pointing gestures as a function of object-manipulation handedness in 123 infants and toddlers (10-40 months). The results showed that not only right-handers but also left-handers and ambidextrous participants tended to use their right hand for pointing. There was a…

Cox, Ralf F. A.; Smitsman, Ad W. – Developmental Science, 2006
Tool use consists of at least two coupled phases of activities, involving multi-step problem solving. It therefore provides an interesting window on the development of planning in goal-directed behavior. This study investigated 2-year-olds' and 3-year-olds' hand use in picking up and subsequently using a tool for displacing a target-object towards…

Bourne, Victoria J.; Todd, Brenda K. – Developmental Science, 2004
Previous research has indicated that 70-85% of women and girls show a bias to hold infants, or dolls, to the left side of their body. This bias is not matched in males (e.g. deChateau, Holmberg & Winberg, 1978; Todd, 1995). This study tests an explanation of cradling preferences in terms of hemispheric specialization for the perception of facial…
