ABSTRACT

Objective : An experiment was performed to investigate the effects of a line-drawing on object recognition and to suggest the importance of an object's internal information on form constancy. Methods : In the experiment, the focus was on a comparison and analysis of whether stimulus types and rotation directions affect the decisions of physical shape sameness of two figures presented successively. Results : The results of the experiment showed that the line-drawing type affects object recognition. A line-drawing-type object was perceived more quickly and accurately than a silhouette-type, and was similar to a shade-type. The accuracy and response time were affected by the change of rotation direction. In particular, a line-drawing effect was seen better than a foreshortened view. Conclusion : These results suggest that the internal information(line-drawing) of an object positively affects object recognition and form constancy.
