Previous research suggests that reaching and walking
behaviors may be linked developmentally as reaching changes
at the onset of walking. Here we report new evidence on an
apparent loss of the distinction between the reachable and
nonreachable distances as children start walking. The experiment
compared non-walkers, walkers with help, and independent walkers
in a reaching task to targets at varying distances. Reaching
attempts, contact, leaning, and communication behaviors were
recorded. Most of the children reached for the unreachable
objects the first time it was presented. Non-walkers, however,
reached less on the subsequent trials showing clear adjustment
of their reaching decisions with the failures. On the contrary,
walkers consistently attempted reaches to targets at unreachable
distances. We suggest that these reaching errors may result from
inappropriate integration of reaching and locomotor actions,
attention control and near/far visual space. We propose a rewardmediated
model implemented on a NAO humanoid robot that
replicates the main results from our study showing an increase
in reaching attempts to nonreachable distances after the onset of
walking. [-]
