Young children can use their subjective straight-ahead to remap visuo-motor alterations

Jenifer Cléa Miehlbradt

Young children and adults process spatial information differently: the former use their bodies as primary reference, while adults seem capable of using abstract frames. The transition is estimated to occur between the 6th and the 12th year of age. The mech ...
