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 Cathexis. 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.

We examined the tickle sensitivity of 46 female psychology students with reference to different areas of the body and cerebral dominance. Analysis indicated a significant difference between two halves of the body for latency and not for duration. The dimensional approach, as we have suggested for other research on cerebral dominance, singled out for both latency and duration of tickle three groups of dominance: right, left, and nondominant subjects.

We examined separately tickle perception and pleasure and anxiety during sexual sequence of 40 dermapathic (20 men and 22 women) and 39 normal subjects (20 men and 19 women) aged between 35 and 40 yr. The dermapathic patients have an inhibitory attitude towards tactile perception of tickling and high anxiety during the sexual sequence. Furthermore, they show positive association of anxiety and pleasure unlike the control group for whom the correlation between the two emotions is negative.

Two aspects of body image (body perception and body acceptance), muscle tone at rest, and disposition to perceive positively connoted stimuli (tickle) were studied with 35 female subjects. Our hypothesized relation of muscle tension and body perception was confirmed by an inverse correlation between these variables. Also evident was the link of the good acceptance of the body with the disposition to perceive pleasurable stimuli (tickle perception) longer and the link of level of body awareness and resistance to change (latency to tickle). Also a direct relationship between body perception and body acceptance emerged.

Barrier and Penetration scores in relation to some variables, such as muscular tone at rest, sensitivity to tickle, and body perception were studied in a group of 35 female subjects. While no correlations appear within the whole group of subjects between Barrier scores and the other variables, on the left side of the body. Dividing subjects on the basis of Barrier scores, three groups with different characteristics appear: 12 subjects with high Barrier scores show an inverse relation of Barrier scores with sensitivity to tickle on the right side of the body; 12 subjects with middle Barrier scores show a direct relation of Barrier scores with muscular tone and an inverse one with both latency of tickle on the right half of the body and body perception; 11 subjects with low Barrier scores show an inverse relation of Barrier scores with durations of tickle on both sides of the body.
