Development of sensorimotor integration of space. Behavioral study of perception and movement parameters in two dimensional space in children
Summary:
In previous studies a systematic directional error (the “motor oblique effect”)
was found in 2D memory pointing movements of healthy adults. In this study we
extend these observations to observe that healthy children (aged 6 – 11 years
old) displayed the same effect.
In contrast other spatial and temporal movement parameters (systematic
amplitude error, square directional and amplitude error, latency and the time
to maximum velocity) changed with increasing age.
Memory delay increased the square directional and amplitude error independent
of age.
Finally, failure of movement inhibition during the delay was more frequent in
children compared to adults.
These results favor the hypothesis that the motor oblique effect related to
perceptual processing biases is constant from childhood while other movement
parameters are modulated by age reflecting the continuing optimization of motor
control from childhood to adulthood.
The dissociation of memory and age effects suggests that motor working memory
is already mature in young children.
