Extracting the regularities of our environment is one of our core cognitive abilities. To study the fine-grained dynamics of the extraction of embedded regularities, a method combining the advantages of the artificial language paradigm (Saffran, Aslin, & Newport, [Saffran, J. R., 1996]) and the serial response time task (Nissen & Bullemer,…

The PFC plays a central role in our ability to learn arbitrary rules, such as "green means go." Previous experiments from our laboratory have used conditional association learning to show that slow, gradual changes in PFC neural activity mirror monkeys' slow acquisition of associations. These previous experiments required monkeys to repeatedly…

A nonverbal false belief task was administered to children (mean age 5 years) and two great ape species: chimpanzees ("Pan troglodytes") and bonobos ("Pan paniscus"). Because apes typically perform poorly in cooperative contexts, our task was competitive. Two versions were run: in both, a human competitor witnessed an experimenter hide a reward in…

The application of modelling to social learning in monkey populations has been a neglected topic. Recently, however, a number of statistical, simulation and analytical approaches have been developed to help examine social learning processes, putative traditions, the use of social learning strategies and the diffusion dynamics of socially…

Monkeys trained in either one-trial recognition at 8- to 10-min delays or multi-trial discrimination habits with 24-h intertrial intervals received systemic cholinergic and dopaminergic antagonists, scopolamine and haloperidol, respectively, in separate sessions. Recognition memory was impaired markedly by scopolamine but not at all by…

Four bonobos, seven gorillas, and six orangutans were presented with two small rectangular boards on a platform. One of the boards had a piece of food under it so that it acquired an inclined orientation whereas the other remained flat on the platform. Subjects preferentially selected the inclined board. In another experiment, subjects were…

Based on observation of children in three cultures, the author concludes that the wild primate model is a fit vehicle for interpreting the play of human children. She then examines the effects and functions of play in order to build a species-specific human theory of play. The implications for education are indicated. (CT)

Comments on Gauvain's discussion, in this issue, of the development of thinking from a sociocultural perspective, expanding her analysis by comparing research on apes who have developed in natural habitats with apes raised by humans in something resembling a human culture. Argues that the study of nonhuman primates can contribute to the emerging…

The nature of science encompasses the entire world and within that realm, patterns of life can be observed, interpreted, and organized into a sensible arrangement of understanding. By discovering, through an intricate process, how shapes and images form into a complete design or sequence, students related similar scientific patterns to their own…

The debate over whether primates can be taught visual language is examined, and evidence of use of nonverbal language in primate studies is compared with the language criteria of a number of linguistic researchers. Background information on language, visual language (including sign language), and the parameters of the studies is offered, including…

Zoo projects that encourage reflective learning and are legitimate undertakings for untrained undergraduates are hard to develop. In this article, the author, as a professor in anthropology, discusses and teaches primate studies. His pedagogical goal in teaching primate studies is to enhance the process of learning, and to consider that students…
