The role of saccade targeting in the transsaccadic integration of object types and tokens.
The presence of location-dependent and location-independent benefits on object identification in an eye movement contingent preview paradigm has been taken as support for the transsaccadic integration of object types and object tokens (J. M. Henderson, 1994). A recent study, however, suggests a critical role for saccade targeting in the generation of the 2 preview effects (F. Germeys, De Graef, & Verfaillie, 2002). In the present study, eye movements were monitored in a preview paradigm, and both location-independent and location-dependent preview benefits were observed regardless of the saccade target status of the preview object. The findings support the view that type and token representational systems contribute independently to the integration of object information across eye movements.
