ABSTRACT
Recent empirical results suggest that there is a decrement in dividing attention between two objects in a scene compared to focusing attention on a single object. However, objects may be made of individual parts. Is there a decrement for dividing attention across different parts of a single object? We addressed this question in two experiments. In Experiment 1, we demonstrated that attention can exhibit part-based selection: Subjects were more accurate in reporting two attributes from the same part of an object than from different parts of an object. In Experiment 2, we demonstrated that part-based attentional decrements occurred simultaneously with object-based attentional decrements. The results from Experiment 2 demonstrated that part-based attention is evident at the same time objects are processed as coherent wholes. Our results imply an attentional mechanism that can select either objects or their parts. |
