In visual attention, there is a distinction between space-based and object-based attention. This study explores object-based attention with a pre-cuing paradigm. Object-based attention has been demonstrated with facilitation to reaction times when the target is in the same object as the cue, as compared to reaction times when the target is equidistant, but in a different object. Experiment 1 tested three different within-object distances to determine whether the object advantage is reduced by a larger within-object distance. Experiment 2 was designed to determine whether attention shifting within the fovea is affected by the object advantage. Results demonstrated that the object advantage is not reduced by greater within-object distances, nor by foveal presentation of the stimuli.
