Abstract
The latent period of the knee jerk is relatively constant for the individual person, as compared with the differences between persons. These differences are attributable largely but not wholly to differences in height, presumably because the length of the reflex arc depends upon height. Tall persons have a longer latent period than short persons. The conduction rate in this reflex arc appears to be 75-80 m. per sec. The authors'' observations reveal no influence on this latent period by other factors studied, including weight, sex, posture, age ("mental" or chronological), intensity of stimulus and the apparent liveliness of response.
