The field of this invention is classifying animal behaviors. In particular the fields of this invention include using animals in vivariums, such as rodents, particularly mice. When two mice socialize, a first mouse vocalizes a call and the second mouse vocalizes a response. Ultrasonic calls and responses are compared to video behaviors of the same mice, and then a table is constructed where each line comprises a particular call and response, a corresponding video behavior, and a correlation weight.
