“…But a similar phenomenon can be shown in rats. For example, Revusky, Coombes, and Pohl (1982) showed that exposing a rat to a flavored liquid in the presence of a poisoned rat established a classically conditioned aversion to that liquid in the first rat. It was as if the sight of the sick rat "instructed" the first rat that ingesting the liquid (the CS) would be followed by sickness (the US).…”

The present paper examines the implications of recent developments in classical conditioning for consumer research. It discusses the finding that the conditioned response need not resemble the unconditioned response, and that the conditioned stimulus must predict but not necessarily precede the unconditioned stimulus for conditioning to occur. The paper also considers the implications of several situations in which classical conditioning may unexpectedly fail to occur, several of the characteristics of classically conditioned behavior, and the role of awareness in conditioning.

“…As Revusky et al (1982) noted, however, the poisoned-partner effect was smaller in magnitude than food aversion produced by poisoning itself. Furthermore, this effect disappeared when subjects were deprived of fluid at the onset of conditioning (Lavin et al, 1980) and when a low intensity of the novel-tasting solution was used as the conditioned stimulus (CS) (Iraola & Alonso, 1995).…”

The effect of prior acquisition of food aversion on the poisoned‐partner effect

It has been suggested that poisoned conspecifics function as aversive unconditioned stimuli for rats. The present study examined whether the prior acquisition of food aversion could enhance this effect. In phase 1, subjects were given pairings of cocoa‐flavored pellets and a toxin. In phase 2, they were given the cocoa‐flavored pellets and later presented with a poisoned or nonpoisoned conspecific. Subsequent testing involved a choice between the cocoa‐flavored pellets and regular pellets. Prior exposure to a poisoned conspecific prevented extinction of the conditioned aversion. In contrast, exposure to a nonpoisoned conspecific allowed extinction of the conditioned aversion. These findings suggest that a rat's reaction to a stressed conspecific is affected by their prior experience of aversive events.

“…Thus, preexposure of the NPP to a number of sick rats prior to the training day diminishes the PPE, as does preexposure of the poisoned partner to LiCI (Revusky et al, 1982). The insertion of a delay between the NPP's consumption of saccharin and exposure to the sick rat attenuates the PPE .…”

“…Following the completion of this study, Revusky et al (1982) published the results of a study indicating that the PPE can be obtained when the NPP is not familiar with its poisoned partner. Specifically, in their Experiment 1, they exposed their NPPs to a procedure in which the NPP was visited by a different partner for 2 h each day every other day for 14 days.…”

Five experiments are reported establishing the poisoned partner effect (PPE) in rats as a robust phenomenon and indicating some of the factors that control its occurrence. Experiment 1 was a replication of Lavin, Freise, and Coombes (1980) and demonstrated that the PPE could be obtained under the conditions they described. Experiment 2 established that the PPE was not due to sensitization. Experiment 3 indicated that the nonpoisoned partner (NPP) had to be familiar with its poisoned partner in order for the PPE to be observed. Experiment 4 established that, under the conditions employed here, the NPP and its sick partner had to be paired together for at least 30 min following poisoning of the latter for the PPE to occur. Finally, Experiment 5 demonstrated that the NPP and its poisoned partner had to be paired together immediately following the poisoning episode. If 40 min or more was allowed to elapse following poisoning before the two were placed together, the PPE was attenuated. Taken together, these results indicate that the time course of the PPE is similar to that of the effects of the poisoning agent and suggest that some stimulus secreted by the poisoned rat and associated with the administration of the poison is the causative factor in the PPE.
