Effects of some factors on relation between visual search and internal representation were examined in real behavioral situations: knowledge in Bonsai appreciation, way of concern in an assembly task, skill in piano playing from a viewpoint of perceptual-motor coordination and useful field of view, and, demands in automobile driving from a viewpoint of useful field of view. Skill and knowledge are prerequisites for formation of efficient and appropriate representation. This was demonstrated through scan-path, span of preview, useful field of view, and temporal stability of perceptual-motor coordination. Furthermore, establishment of procedure of behavior was suggested to be significant for formation of representation. On the other hand, it was demonstrated that useful field of view becomes narrower under demanding situations because of limitation of attention resource.
