Jongbloed-Pereboom, Marjolein; Nijhuis-van der Sanden, Maria W. G.; Saraber-Schiphorst, Nicole; Craje, Celine; Steenbergen, Bert – Journal of Experimental Child Psychology, 2013
The primary aim of this study was to assess the development of action planning in a group of typically developing children aged 3 to 10 years (N = 351). The second aim was to assess reliability of the action planning task and to relate the results of the action planning task to results of validated upper limb motor performance tests. Participants…

Claxton, Laura J.; Melzer, Dawn K.; Ryu, Joong Hyun; Haddad, Jeffrey M. – Journal of Experimental Child Psychology, 2012
The postural sway patterns of newly standing infants were compared under two conditions: standing while holding a toy and standing while not holding a toy. Infants exhibited a lower magnitude of postural sway and more complex sway patterns when holding the toy. These changes suggest that infants adapt postural sway in a manner that facilitates…

Deutsch, Katherine M.; Newell, Karl M. – Journal of Experimental Child Psychology, 2001
Examined whether age-related improvements in children's motor performance result from reduced noise in the output of the sensorimotor system. Found that performance improved with age. The force output signal exhibited increased irregularity and a more broadband frequency profile with increasing age under feedback. There were no age differences in…

Badan, Maryse; Hauert, Claude-Alain; Mounoud, Pierre – Journal of Experimental Child Psychology, 2000
Four experiments investigated the development of visuomotor control in sequential pointing in tasks varying in difficulty among 6- to 10-year-olds and adults. Comparisons across difficulty levels and ages suggest that motor development is not a uniform fine-tuning of stable strategies. Findings raise argument for stage characteristics of…
