| Outline of Final Research Achievements |
We aimed to determine how Japanese monkeys acquire the motor-movement for tool (forceps) use after kinematic analysis under the Guide for the Care and Use of Laboratory Animals by the National Research Council. Three monkeys had already learned to use forceps to pick up food using the right hand when the forceps were presented in their front-right side facing food placed on their left (Hirai et al., 2010). When we presented the same forceps with opposite orientation of the original, they refused to act on the forceps. However, they learned to handle the forceps at any orientation in 10-12 days through their active and, importantly, individual learning processes of forceps use reflecting different experience. We can draw out the latent abilities of the monkeys to use a pair of forceps as a “tool”; they had the ability to do the following: 1) conduct advance planning and 2) possess potential knowledge of the causal relationship between their own action on the forceps and its result.
