Abstract
Experiments of curvilinear cutting with scissors and shears were made on female elementarY school pupils and female adults under the same conditions as those of the straight-line cutting reported in Part 1, and the two results were compared and examined.
The results were as follows :
1. The same characteristic pattern as in the straight-line cutting was observed both in the respiration curve and in the E.M.G. of the “experienced.”
2. Because higher technique is required in curvilinear cutting, the increase both in the time required and in the frequency of cutting motion was observed in the “inexperienced.” The discordance between the rhythm of breathing and that of cutting motion was also observed in many cases.
3. As far as the very “skillful” and “unskillful” were concerned, there was an approximate coincidence between the evaluation of the graphs and that of their works as in the straight-line cutting.
