However, the results for the 5-year-olds show that the tilting movement does not just facilitate
imagery performance by yielding visual information about the transformation because there was just
as much visual information available in the remote control task. Furthermore, this result challenges
the suggestion of Schwartz and colleagues (Schwartz, 1999; Schwartz & Black, 1999) that motor activity
facilitates imagery by generating timing information, or information about the changes in time and
space, because such spatiotemporal information was also abundantly available in the remote control
task. Apparently, the active execution of the tilting movement conveys more information than the
visually observed movement in the remote control task could provide—at least for younger children.
Therefore, it is more likely that motor activity facilitates imagery by activating motor knowledge or
motor schemata. This seems especially plausible if we take into account that the water tilting task requires
a simulation of how gravity and tilting the container cause the water to deform in a nonrigid
manner. Thus, the motor system might tap into such implicit causal schemata that might not yet
be accessible through visual simulation or reflection.
