“…Most sexually dimorphic behaviors are actually dimorphic in the sense that one sex is more likely to perform them, rather than that they are exclusive to one sex (Aron, Chateau, Schaeffer, & Roos, 1990; Goy & Roy, 1990). For example, mounting and thrusting are male-typical behaviors, which in males are changed from high-threshold behavior patterns (female-typical) to low-threshold behavior patterns (male-typical) because of the influence of androgens in the perinatal stage of development (masculinization).…”

In rats (Rattus norvegicus), juvenile males engage in more play fighting (a male-typical behavior) than do juvenile females, and this difference is based on perinatal influences of androgens. We show that there are qualitative and quantitative differences between the sexes in the type of defensive responses and their manner of execution. In defensive responses rats try to avoid having their napes contacted by the partner's snout. The sex differences arise from females' greater response distance; that is, females responded to an approach when the partner's snout was further from the nape. This permits females to use different defensive responses and to use them more successfully. This greater response distance is defeminized by the neonatal administration of testosterone propionate. Our findings suggest that play fighting in rats has both male- and female-typical features and that these are, at least in part, influenced perinatally by androgens.

“…Sex differences in mammals exist in both reproductive (Ward, 1992) and nonreproductive (Beatty, 1992) behaviors. Most sexually dimorphic behaviors, however, are dimorphic only in the sense that one sex is more likely to perform them than is the other (Aron, Chateau, Schaeffer, & Roos, 1991; Goy & Roy, 1991). Except for some behavior patterns associated with parturition, most sexually dimorphic behavior patterns are described as sex typical, not sex exclusive.…”

Rats protect food by dodging horizontally away from a conspecific. Females and males use different movement and stepping patterns to execute a dodge. An unresolved question is whether exposure to ovarian steroids in females is necessary for the development of the female-typical pattern. Females ovariectomized neonatally and prior to puberty use a combination of male and female tactics. Pregnant females, however, use a female-typical pattern of dodging, suggesting that the patterns used by prepubertal ovariectomized females are not due to their increase in body mass. Thus, the contribution of ovarian steroids to the development of female-typical patterns of behavior needs to be studied further at both a behavioral and neural level with regard to the organization of movement.

Food-deprived rats (Rattus norvegicus) will protect their food by dodging away from a conspecific. A detailed kinematic analysis of these movements in adult rats shows that each sex uses sex-typical movements. Females move their snout through a greater spatial curvature, and their snout achieves a greater velocity, relative to the pelvis, than males. Males make more hindpaw steps than females and achieve a more simultaneous movement of the fore- and hindquarters. This suggests that females pivot around a point more posterior on the body than males. The finding that functionally similar patterns of movement have a sex-specific organization provides a new dimension for the study of sex differences. These differences are discussed in relation to sex differences in sex-typical behaviors, associated body structure, and neural control.
