This study was designed to better understand the process underlying the learning
of goal-directed locomotion. Subjects walked on a treadmill in a virtual reality
setting and were asked to cross pairs of oscillating doors. The subjects
behaviour was examined at the beginning of the learning process (pretest), after
350 trials (intermediate test), and after 700 trials (posttest). The data were
analysed at three different levels, each representing a specific aspect of the
global response: performance outcome, displacement kinematics, and current
arrival condition. While some aspects of performance outcome suggested the
presence of a ceiling effect in the intermediate test, both displacement
kinematics and current arrival condition clearly highlighted continuous
transformations of the control mechanism involved. The learning process is best
described as (1) the establishing of a relationship between specific information
and a movement parameter and (2) the optimization of this relationship. The
optimization process is characterized by the further exploration of the available
behavioural repertoire and by the refinement of the dialogue between information
