Abstract: | I made systematic observations of three infant chimpanzees aged 2–4 years, who participated in a series of diagnostic tests
of combinatory manipulation. The tasks were stacking blocks, seriating nesting cups, and inserting an object into the corresponding
hole in a plate or a box. These tasks were originally devised for developmental diagnosis of human infants. The chimpanzee
infants displayed combinatory manipulation comparable to that of 1-year-old human infants. Common motor characteristics were
observed across the tasks, namely "repetition" of actions, "adjustment" of actions, "reversal" of actions, and "shifts" of
attention. Humans and chimpanzees share these actions when manipulating multiple objects to complete a task. Repetition, adjustment,
and reversal of actions and shifts of attention underlie higher levels of cognition common to both species.
