TL;DR
Stimulation of catecholamine systems is evidently incompatible with the expression of playful behavior and at the highest doses tested both amphetamine and methylphenidate increased social investigation, but only if the rats were socially isolated.
Abstract
Treatment with d-amphetamine (0.125-1 mg/Kg) or methylphenidate (0.5-4 mg/kg caused dose-dependent decreases in play fighting in juvenile rats which were independent of sex and strain. Although brief social isolation profoundly increased play fighting, qualitatively similar drug effects on play were observed in socially housed and isolated animals. By contrast, at the highest doses tested both amphetamine and methylphenidate increased social investigation, but only if the rats were socially isolated. Stimulation of catecholamine systems is evidently incompatible with the expression of playful behavior.

The data indicate that social play can be efficiently studied in the laboratory rat and, further, that one function of play may be to establish stable social relationships.

With spontaneous activity as a measure of arousal, dose response curves were established for scopolamine and amphetamine administered to 10, 15, 20, 25, and 100-day-old rats, which suggests that adrenergic excitatory areas in the brainstem mature more rapidly than cholinergic inhibitory Areas in the forebrain.
Behavioral and Neural BiologySocial deprivation and play in rats
411 Citations1980Jaak Panksepp, William W. Beatty
Social interaction (play fighting) was studied in socially housed and individually housed juvenile rats and pinning proved to be a simple measure of play which correlated highly with other measures of playful behavior.
Animal BehaviourA descriptive study of social development in the rat (Rattus norvegicus)
409 Citations1981Michael J. Meaney, Jane Stewart
Clear patterns in the development of sexual and agonistic behaviours in the rat were revealed and development toward the adult pattern of social behaviour was temporally associated with the period of sexual maturation.
Life SciencesIntermittent versus continuous stimulation: Effect of time interval on the development of sensitization or tolerance
386 Citations1980Robert M. Post
It is suggested that the interval between electrical, drug, or psychological stimuli is important in determining subsequent responsivity and may shed light on similarities and differences in mechanisms underlying tolerance and sensitization.

269 Citations1974Klaus A. Miczek
The results indicate that amphetamine and chlordiazepoxide can facilitate or inhibit attack or defense depending on the dose level and which of the opponents was injected, but do not reverse dominance-subordination relationships.

A triple-layered model of psychosis is suggested and the roles played by participating neurotransmitters and mechanisms are further elaborated.
Animal BehaviourPlay as a reinforcer for maze-learning in juvenile rats
200 Citations1981Anne P. Humphreys, Dorothy Einon
The reinforcing value of play for juvenile rats was examined, relative to that of other social experiences, and non-playing partners indulging in large amounts of amicable social behaviour were chosen more frequently than unsociable animals.

The test of aggressiveness in mice caused by prolonged isolation was employed to evaluate the possible anti-aggressive activity of a number of centrally active drugs.
Brain ResearchApomorphine-induced aggression in the rat
88 Citations1971Gerald M. McKenzie
The results suggest that the apomorphine-induced aggressive behaviour as well as the similar mock-fighting behaviour following l -DOPA or dexamphetamine, as reported by other authors, is probably a consequence of enhanced activity at dopaminergic receptors.

56 Citations1968A. Lammers, J.M. van Rossum
Male rats given a combination of the peripheral DOPA decarboxylase inhibitor Ro 4-4602 and DOPA, showed motor excitation as well as a peculiar and bizarre pattern of social behaviour, and the possible role of brain dopamine in this social behaviour is discussed.

49 Citations1976John D. Gambill, Conan Kornetsky
The responses to drug treatment in subordinant rats may provide a model for the social behavior of frightened paranoid schizophrenics.
PsychopharmacologyStages of constant amphetamine intoxication: Delayed appearance of abnormal social behaviors in rat colonies
45 Citations1978Gaylord Ellison, Michael S. Eison +1 more
This late phase of constant amphetamine intoxication in rats has a number of similarities to amphetamine psychosis in humans, and can serve as a useful animal model for the study of its biochemical correlates.
ScienceParadoxical Effects of Amphetamine on Preweanling and Postweanling Rats
31 Citations1977Byron A. Campbell, Patrick J. Randall
It is reported that amphetamine administered to preweanling rats in the presence of an anesthetized adult rat produces no visible increase in motor activity, and amphetamine appears to enhance the normal tendency of neonatal rats to approach and maintain contact with conspecifics.
