The Effect of Objecthood on Processing Efficiency


The term objecthood is used to convey the degree of image regularity in terms of properties such as closure, symmetry and parallelism. The notion of objecthood is evaluated in the light of the existing psychological data on sensory-driven biases of attentional selection. Extending the biased competition for selection framework, we tested if higher objecthood of the image modulates its salience and exerts influence on the efficiency of its processing. In a series of three experiments, it is demonstrated that the presence of closure significantly impacts processing efficiency of the presented visual stimuli.
