Suppression of fighting was effective in all pairs tested over 14 daily sessions.
WebDrug addiction is thought to be driven by negative reinforcement, and it is thought that a shift from positive affect upon initial exposure to negative affect after chronic exposure to a drug is responsible for maintaining self-administration (SA) in addicted individuals. This can be modeled in rats by analyzing ultrasonic vocalizations (USVs), a type of intraspecies … WebFor example, Reynierse (1971) has described the shock-elicited fighting behavior of naive albino rats as "a low intensity mood which becomes increasingly less descriptive of laboratory rat ...
WebAbstract Light and dark reared, social and isolate housed, male Long-Evans hooded rats were tested in bright and dim light for aggressive response to footshock. Test lighting and socialization main effects were significant, with greater fighting in dim light than in bright light and greater fighting by isolates than by socially housed animals.
