§7 Can animals imitate? The âtrue imitationâ theory and its flaws
If a non-human animal copies the general pattern of behavior that provokes an interesting resultâeven a behavior that is unfamiliar to her and not part of the action repertoire of her speciesâthis cannot be called true imitation, a number of eminent scientists assert.6 The argument goes as follows: Non-human animals do not focus on the detailed topography of the gestures performed by the model, but, instead, on the result of the action, the affordances of the tools, or a rough pattern of actions that can be exploited by each individual according to its own behavioral strategies. A non-human animal can roughly do as the model does: She selectively reproduces some aspects of the model's gestures.7 Does she not imitate? This looks like imitation, but, according to the âtrue imitationâ theory, this should be called emulation learning8 based, for instance, on local and/or stimulus enhancement.9 In other words, apes do not ape:10 Smart trick, indeed. Michael Tomasello, a prominent researcher in the field of Evolutionary Anthropology, did not dither too long before concluding that only humans are capable of true imitation11 and he contended that the latter is the backbone of culture, namely a highly cumulative evolution12, a.k.a. true culture.13 Cultural evolution, the argument goes, is a process in which ever new ways of doing things are noticed and transmitted. Without a capacity for true imitation, such unique features would never be retained; they would be lost in a schematic reproduction of general patterns of behavior.
Several daring and debatable metaphysical presuppositions are actually at work in this approach under the guise of a fine-grained description of the lineaments of behaviors. Even a half-attentive reading can ferret out symptoms of such biases: The phrase âtrue imitation,â for instance, can only set off some alarms, as its proponents themselves sense it.14 Certainly, the issues raised by this platonic approach warrant a more detailed look.
The âtrue imitationâ theory chooses to radically break with the common sense of âimitationâ and loses touch with vernacular language.15 To be sure, the latter is often loose and sometimes conflates what should be kept separate. Nonetheless, in this case, as often, everyday language acknowledges a similarity between behaviors, that is an integral part of the phenomenality of these behaviors and that a fine-grained description should integrate into its account. Common language possesses a fluidity and a flexibility that makes a more comprehensive description possible and, correlatively, sustains an ethics of community that is also crucial in animal studies. Indeed, in this particular theory of true imitation, is Tomasello interested in paying attention to animals or, eventually, in finding a way of reasserting human uniqueness? Nevertheless, shouldnât a scientific approach use clearly circumscribed concepts? It is significant, however, that De Waal chooses, for instance, the phrase âselective imitationâ to designate behaviors that the proponents of the âtrue imitationâ theory would call âemulation learning.â
More specifically, several researchers have strongly challenged the true imitation theory. Andrew Whiten and Deborah Custance,16 for instance, develop criticism based on meticulous experiments, but also on a reflection on the most accurate method that should be used to shrewdly account for such experiments. Many experiments show that animals of several species can actually truly imitate;17 hence, they challenge Tomasello's theory without challenging his concept of imitation. By contrast, the general thrust of Whiten and Custance's work, such as it is presented in Heyesâ and Galef's Social Learning in Animals: The Roots of Culture, is that drawing a clear boundary between emulation and imitation is impossible.
There is indeed a dimension of imitation in the behaviors that some have tried to describe exclusively in terms of emulation.
a First, no imitation can be perfect, not only because perfection is only divineâwhich makes true imitation an âever elusive,â although still pertinent, idealâbut more fundamentally because imitation essentially implies duplication, de-centration, and, consequently, some modifications. The body of the imitator is not exactly the same as the body of the model, even more so in frequent cases of interspecific emulation learning. As pointed out by Whiten and Custance, âAll imitative copies must have a schematic or program-like character, because not every muscle twitch is going to be copied.â18 Identity and imitation are antinomic. The very concept of true imitation as a slavish process that sticks to every possible detail of an action is an unviable monster. This concept additionally enters into tension with another version of the true imitation theory. Tomasello sometimes argues that proper imitation should imply understanding of the intentions that rule the acts of the imitated model.19 But such an understanding essentially consists in generalizing and catching, at least performatively, the outline structure of a task that can be reapplied to ...
