The dance metaphor for the communication between two organisms may be an appealing image because it appears to capture the intricate synchronization of their interaction; however, it is neither parsimonious nor easily tested. Instead, a multichannel information-processing model, even one that can process only serial events, provides all of the flexibility required to account for the complex temporal coordinated action observed.

The authors make a distinction between instrumental copying behavior in which there is a clear reward for the copying behavior and social copying (traditions) in which the rewards for copying are less clear. However, I see no reason to distinguish between the two. We are social animals, for whom copying traditions have important rewards, those of affiliation.

It is assumed that self-control always has a higher value. What if it does not? Furthermore, although there are clearly intrinsic reinforcers, their measurement is problematic, especially for a behavioral analyst. Finally, is it more parsimonious to postulate that these behaviors are acquired rather than genetically based?

Framing effects attributed to “quasi-cyclical” irrational complex human preferences are ubiquitous biases resulting from simpler mechanisms that can be found in other animals. Examples of such framing effects vary from simple learning contexts, to an analog of human gambling behavior, to the value added to a reinforcer by the effort that went into obtaining it.

The authors' attempt to explore the ability of animals to monitor how certain they are of their choice behavior, necessarily fails both in their effort to include “higher” mammals (such as monkeys and dolphins) in the class of metacognitive organisms (humans) and in their conclusion that “lower” organisms are not capable of similar behavior.

Byrne & Russon propose that priming can account for the imitation of simple actions, but they fail to explain how the behavior of another can prime the observer's own behavior. They also propose that imitation of complex skills requires a sequence of acts tied together by a program, but they fail to rule out the role of trial-and-error learning and perceptual/motivational mechanisms in such task acquisition.

The hypothesis proposed by Macphail is that differences in intelligent behavior thought to distinguish different species were likely attributed to differences in the context of the tasks being used. Once one corrects for differences in sensory input, motor output, and incentive, it is likely that all vertebrate animals have comparable intellectual abilities. In the present article I suggest a number of tests of this hypothesis with pigeons. In each case, the evidence suggests that either there is evidence for the cognitive (...) behavior, or the pigeons suffer from biases similar to those of humans. Thus, Macphail’s hypothesis offers a challenge to researchers to find the appropriate conditions to bring out in the animal the cognitive ability being tested. (shrink)

Social influence and social learning are important to the survival of many organisms, and certain forms of social learning also may have important implications for their underlying cognitive processes. The various forms of social influence and learning are discussed with special emphasis on the mechanisms that may be responsible for opaque imitation (the copying of a response that the observer cannot easily see when it produces the response). Three procedures are examined, the results of which may qualify as opaque imitation: (...) the bidirectional control procedure, the two- action procedure, and the do-as-I-do procedure. Variables that appear to affect the emergence of opaque imitation are identified and other complex forms of response copying are discussed. Keywords: bidirectional control procedure; contagion; emulation; imitation; local enhancement; object movement reenactment; observational conditioning; opaque imitation; social enhancement; social facilitation; social influence; social learning; stimulus enhancement; two action procedure.

Heyes discounts findings of imitation and self recognition in nonhuman primates based on flimsy speculation and then indicates that even positive findings would not provide evidence of theory of mind. Her proposed experiment is unlikely to work, however, because, even if the animals have a theory of mind, a number of assumptions, not directly related to theory of mind, must be made about their reasoning ability.

: At the center of Catherine's Malabou's study of Hegel is a defense of Hegel's relation to time and the future. While many readers, following Kojève, have taken Hegel to be announcing the end of history, Malabou finds a more supple impulse, open to the new, the unexpected. She takes as her guiding thread the concept of "plasticity," and shows how Hegel's dialectic--introducing the sculptor's art into philosophy--is motivated by the desire for transformation. Malabou is a canny and faithful reader, (...) and allows her classic "maître" to speak, if not against his own grain, at least against a tradition too attached to closure and system. Malabou's Hegel is a "plastic" thinker, not a nostalgic metaphysician. (shrink)

: In the early twentieth century, psychoanalysis tries to investigate a specific logic of the appearance and the incident of what is taken to be unintended in everyday communication and human behavior. What before hardly seemed to be worth systematic research, now becomes a privileged field, in which the meaningful signs of a hidden and unwelcome past appear. For representing this new field of research Freud often makes use of archaeological metaphors. But in quoting the knowledge and the techniques of (...) archaeology, he evokes imaginary landscapes of a reappearing human past, which is not depraved and repressed but glorious and precious. This contradiction or gap between the character of analytical objects and their representation gives reason for an 'archaeological' investigation of psychoanalysis itself. To this end one of the heroes of nineteenth century archaeology, Heinrich Schliemann, will be confronted with two little works of Rudolf Virchow, in which he follows up the astonishing idea of an archaeology of refuse. Relating treasure troves and rubbish dumps it can be asked whether 'archaeological' practices in the late nineteenth century constituted a type of historical knowledge which runs counter to contemporary historicism and is crucial not only for Freud but also for today's theoretical reflections on archaeological perspectives in cultural studies.
