Manual rotation training improves direction-estimations in a virtual environmental space

This study investigated in a virtual environment, whether the training of a small-scale ability, i.e., manual or mental rotation, has an influence on the large-scale ability to estimate a direction. Ninety-six participants completed a direction estimation task as a pretest and then received either a manual rotation or a mental rotation training or played a nonspatial computer game. After that they completed the direction estimation task once again. The results showed that the direction estimation error decreased from the pre- to posttest only for the manual rotation training group. For that, the small-scale spatial ability was at least partially related to the large-scale ability, which supports the Partial Dissociation Model.
