| Research Abstract |
The present study aimed to cralify the similarity and difference between humans and chimpanzees in perceptual and cognitive processes. The topics were as follows.
NUMBER PERCEPTION : A chimpanzee named Ai, 16 years old female, learned to label the number of dots presented on a CRT screen and asked to choose a crresponding Arabic numeral on the other CRT screen.
She learned to label one through ten, and her accuracy of the performance reached to 85% correct when the numbers were presented randomly. It means that the chimpanzee showed a rudimental ability of processing the numbers.
MEMORY PROCESS : The chimpanzee also learned to remember the strings of numerals up to six. The task is so-called matching to sample. She can reproduce 6 numerals in a string, where she spontaneously developed her favorite order of reproducing the string from center to right then back to left. She also learned to 2 numerals and reproduce then after short period of delay interval.
PATTERN PERCEPTION OF KANJI : The chimpanzee learnd to do matching to sample of Kanji-characters. 40 Kanji characters were used as samples. She discriminated those 40 characters at about 80%
