| Research Abstract |
Cultural behavior patterns of wild chimpanzees at Mahale were observed in feeding, tool-use, grooming, play, courtship displays, and intimidation displays. We clarified the general developmental processes behind cultural behavior."Grooming hand-clasp"was examined as a process of social learning. It's likely that the form itself is transmitted by"Molding"by the mother, but its fine patterns seem to be determined by the individual's own trial-and-error learning. Some novel behaviors of which more than forty were recorded, were frequently observed over time. However we concluded that there is only a small possibility that these are fixed as cultural behavior.
