After fear conditioning (e.g., by pairing a tone to a shock), memory retrieval typically leads to fear expression (e.g., freezing to the tone). Here, we examined the effect of a conditioned rat's fear memory retrieval on a naïve cage-mate's behavior to the conditioned stimulus. We show that rats exposed to a novel tone in the presence of a cage-mate previously conditioned to that same tone selectively showed increased freezing to the stimulus the next day (fear conditioning by-proxy). In addition, fear conditioning by-proxy experienced prior to pairing the tone to a mild shock increased freezing during presentation of that tone the next day. Our results suggest that, during memory retrieval, fear of a stimulus can be socially transmitted to a cage-mate. These findings may have implications for models of phobias.
