Event Abstract

Spatio-temporal correlates of feature binding during object-based attention

  • 1 Otto-von-Guericke University, Germany

Attentional selection can be based on single feature such as color or motion. Measures of EEG and MEG were employed to investigate the temporal dynamics of feature selection during object-based attention. Stimuli consisted of overlapped arrays of dots moving in opposite directions that were perceived as two integral surfaces (objects). Attending an object feature (motion) facilitated the processing of an irrelevant feature (color) of the same object with a delay of 40-50 ms. Importantly, when the task changed and color was the attended feature of the object enhanced processing was observed first in color and later in motion-related areas. These findings indicate that the rapid attentional selection of visual features within objects is highly flexible, with the order of feature selection being determined by task demands.
