Rough-and-tumble play or play fighting is an important experience in the juvenile period of many species of mammals, as it facilitates the development of social skills, and for some species, play fighting is retained into adulthood as a tool for asse

Juvenile play experiences promote behavioral flexibility in rats. If other early positive experiences, such as tactile stimulation, are given prior to exposure to psychostimulants, the behavioral response to the drug is attenuated. The objective of t

Whether it is that animals are young so that they can play, or whether it is that they play because they are young, play should be more prevalent in species that have a greater degree of postnatal development. This hypothesis is tested by comparative

When protecting a food item held in the forepaws, rats will dodge laterally away from an approaching conspecific. Both males and females dodge, but do so differently, with females pivoting around the pelvis and males pivoting around the midbody. Whil

Play fighting in its most elaborate form involves nonagonistic wrestling between pairmates, where one partner grabs, holds, bites, or otherwise contacts the other. Such play occurs in the absence of the functional consequences associated with serious

Due to the action of testicular hormones in the perinatal period, juvenile male rats engage in more play fighting than juvenile females. Also, following puberty, males, but not females, switch to using adultlike defensive tactics more frequently duri

Play fighting in rats is most frequent in the juvenile phase (30-40 days) and then wanes following puberty. During the juvenile phase, the most commonly used defensive tactic to block access to the nape (i.e., the play target) is to rotate around the

Feeding rats dodge laterally away from a conspecific attempting to steal their food. Dodges by female and male rats differ in their composition of movement. Females pivot around a point more posterior on the longitudinal axis than do males, producing

Three experiments were conducted to investigate the phenomenon of atropine-induced stereotypic trapping in rats reported by Schallert, De Ryck, and Teitelbaum (1980). The first two showed that such trapping was disrupted by previous experience with t
