A group of 20 middle-class women between 20 and 40 yr. of age and in the third trimester of pregnancy was compared with a control group of 20 non-pregnant women for cutaneous sensitivity (to a tickle) and for modifications of body schema which were hypothesized to occur during pregnancy. Latency and actual duration were considered in the perception of the tickle. Body schema were studied using two of Fisher's tests, Body Prominence and Body Carhexis. Pregnancy leads to modifications in sensitivity to tickle, specifically with regard to the right half of the body and to some extent in body schema.
