I went to observe juvenile individuals of Western Lowland
Gorillas in Bronx zoo, NY, USA. Observation was done for four hours in
close distance and I found many play-repertories among their playing
behavior; Some of them seemed very common with chimpanzees (ex. 'circle'),
and others seemed specific to gorillas (ex.'drumming behavior'). On the
other hand, I could not find any play behavior between juveniles and their
father (silverback). I participated in the conference of TASP/IPA
(International Play Association) as a presenter at Strong National Museum
of Play, Rochester, NY.
I presented in two sessions, one in oral and the other in poster
session. After my presentation, many participants gave me valuable
comments or questions. Through the conference, I found it very impressive
and significant that I could make many connections with American and
Canadian scientists studying play of human children, and we exchanged our
information and proposed concrete cooperative studies on play.
