Through learning, one can discriminate an object from similar distracters even if they are seen from different viewing angles. Previously, we have shown that the discrimination of images at several individual viewing angles produced immediate association across the views of the same object if the difference in the viewing angle was relatively small. To understand the underlying mechanism for the association of largely separated views, here we investigated how the association was influenced by the presentation of interpolated views. We found that the association learning was significantly enhanced if with the prior experience of interpolated views, and furthermore, showed that the establishment of such association was not due to the reinforced pairing, because reaction times were influenced by the amount of difference in viewing angles. The results suggest that the mechanism underlying the association of largely separated views is different from that for the views with relatively small difference.
