“…For example, there is evidence that dogs (Settle, Sommerville, McCormick, & Broom, 1994), sheep (Fell & Shutt, 1989), pigs (Tanida, Miura, Tanaka, & Yoshimoto, 1995), and prairie dogs (Slobodchikoff, Kiriazis, Fischer, & Creef, 1991) can tell humans apart. However, there is as yet no comparable evidence that rats can distinguish individual people.…”

Many "higher" animals are commonly assumed to distinguish between individual humans. This belief is based largely on anecdotal reports; in reality, there is little empirical evidence to support human recognition in nonhuman species. Wereport that laboratory rats consistently chose a familiar human over an unfamiliar human following fourteen and five IO-min exposures and even following a single IO-min exposure. Furthermore, this preference was retained in the absence of additional contact for at least 5 months. These results confirm that laboratory rats can tell individual humans apart, a prerequisite for associating them with hedonic events. Such human-based conditioning, described by Pavlov and by Gantt, Newton, Royer,and Stephens (1966),may have important implications for animal research in a variety of settings.Can the ubiquitous laboratory rat recognize individual humans? There is evidence that, like many animals, rats can discriminate individuals within their own species (Halpin, 1980; Hopp, Owren, & Marion, 1985;Randall, 1989). Indeed, Thor and Holloway (1982) describe rats as "normally engaging in spontaneous learning of individual identity" (p. 1000). But can such individuals be of another species, and, more specifically, can they be human?The recognition by animals of individual humans is not without precedent. For example, there is evidence that dogs (Settle, Sommerville, McCormick, & Broom, 1994), sheep (Fell & Shutt, 1989), pigs (Tanida, Miura, Tanaka, & Yoshimoto, 1995), and prairie dogs (Slobodchikoff, Kiriazis, Fischer, & Creef, 1991) can tell humans apart. However, there is as yet no comparable evidence that rats can distinguish individual people.Whether rats can discriminate between humans may have implications beyond the study of animal cognition. If research animals, such as rats, can differentiate one human from another, and this human is repeatedly paired with significant hedonic events in the animal's life, Pavlovian conditioning is likely to occur. Most research entails the delivery of hedonic stimuli, either through daily care or experimental manipulation. Gantt, Newton, Royer, and Stephens (1966) recognized this human-based conditioning process and described it in terms of "person as CS." Davis and Balfour (1992) surveyed evidence that such an associative process may have motivational effects that raise methodological concerns for animal-based research.This research was supported in part by Grant A0673 to the first author from the Natural Sciences and Engineering Research Council of Canada. All animals were cared for in accordance with the University of Guelph Animal Care Policy and Canadian Council on Animal Care guidelines. A portion of these data was reported at 1994 meetings ofthe Animal Behavior Society and the Psychonomic Society.
