Abstract
In several studies with hierarchical stimuli it has been shown that the left and the right hemispheres are specialized for the processing of local and global information, respectively. However, although corresponding visual-field (VF) effects regularly show up for incongruent stimuli, they are often absent for congruent ones. In this study, it was investigated whether the spacing between the elements of the stimuli has any effect on this phenomenon. Therefore, in Experiment 1, stimuli with narrowly spaced elements were applied. As a result, VF-effects occurred independently of the congruency condition. For comparison, stimuli with wider element spacing were used in Experiment 2. Under these conditions, VF-effects occurred again, as expected, only for incongruent stimuli. These results show that element spacing can have an effect on VF-effects. The results are interpreted in the sense that narrowly spaced elements are perceived as texture, which always leads to an elaborate mental representation of the stimulus that differs between the hemispheres.
