[The contagious behavior model on the basis of rat drinking behavior]

In work, the attempt of contagious behavior modeling on the basis of rat drinking behavior was made. Rats' behavior was observed in home cage with two bottles. The rat without drinking motivation (viewer) was placed in the cage for adaptation. The rat-demonstrator was placed into the same cage 3 minutes later. If the viewer was tested with drink-motivated demonstrator, it had less latency of approach to bottles, higher frequency of approaches and increased drinking behavior time than the rat tested with unmotivated demonstrator or the rat tested without demonstrator. The intragastric infusion of coffee increased frequency of approaches to demonstrated bottle. Phenazepam intragastric injection decreased frequency of approaches and drinking behavior time at demonstrated bottle. The results suggest that drugs may affect rat contagious behavior based on drinking behavior.
