It also provides the basis for optimizing graphical material design to insure best retention…

Mature'' judgments of causality appeared earlier for social situations (between ages 4 and 7) than for physical ones (between ages 7 and 11). (Author)

Three experiments involving 107 adults who performed mental rotation tasks explored how location information is incorporated into image representation.
