| Research Abstract |
We have investigated the various aspects of the dynamic mental representations in nonhuman and human primates, such as chimpanzees, New World monkeys macaques, and human adults and infants, from the comparative-cognitive and comparative-developmental perspectives. Main research topics am the perception of dynamic changing images, change detection, depth perception, attention to dynamic changing objects, Effects of top-down knowledge on the various kinds of perception and cognition.
As a result, we found similarities among species in the processing of dynamic changing environments. Chimpanzees exhibited efficient detection of face among non-face distractors. They further showed efficient detection of upright face. Chimpanzees showed difficulty in detecting the changes with temporal gaps (change blindness) as humans do. When they judged the direction of movement of object, their judgments were affected by the "directedness" of objects. Human infants exhibited the perception of pictorial depth better when the motion information was added. Such facilitative effects were also observed in macaques and chimpanzees. On the basis of these findings we have discussed the emergence of dynamic mental representations in ontogeny and phylogeny.
