Abstract
Motion contributes to object recognition, particularly if shape is visually similar or if an object moves the same way on different encounters. Here we examined how shape diagnosticity and motion variability may interact and contribute to recognition. Observers learned novel objects that rotated in depth in a constant or variable way on each trial. For shape-nondiagnostic objects, constant motion lead to faster learning and variable motion resulted in more robust representations to changes to object dynamics. By comparison, for shape-diagnostic objects, performance was similar with both types of motion and remained sensitive to changes to object dynamics.
