Abstract
Although young laboratory rats play vigorously when taken from isolation and presented with an acceptable play partner, their positive play behaviors gradually decline over the course of a prolonged (30-‐minute) play session. Additionally, some rats begin to make vocalizations in the 22-‐kHz range, which may indicate a negative emotional state. This study first took an observational approach to attempt to determine if the decline in play behaviors in these animals was due to the rise of a general negative-‐affective state. Animals were observed during 30-‐ minute play sessions throughout adolescence to attempt to tease out relationships between vocalizations and corresponding play behaviors. Subsequently, a “psychoassay,” based around a standard tickle test attempted to determine the affective phenotypes of these animals.
