Abstract: This research examined token-mediated tool-use in a tufted capuchin monkey (Cebus apella). We conducted five experiments. In experiment 1 we examined the use of plastic color-coded chips to request food, and in experiments 2-5 we examined the use of color-coded chips to request tools. Our subject learned to use chips to request tools following the same general pattern seen in great apes performing analogous tasks, that is, initial discrimination followed by an understanding of the relationship among tokens, tools, and their functions. Our findings are consistent with the view that parallel representational processes underlie the tool-related behavior of capuchins and great apes.

Griffin, D. R. (1998). From cognition to consciousness. Anim. Cogn., 1(1), 3–16.
Abstract: This paper proposes an extension of scientific horizons in the study of animal behavior and cognition to include conscious experiences. From this perspective animals are best appreciated as actors rather than passive objects. A major adaptive function of their central nervous systems may be simple, but conscious and rational, thinking about alternative actions and choosing those the animal believes will get what it wants, or avoid what it dislikes or fears. Versatile adjustment of behavior in response to unpredictable challenges provides strongly suggestive evidence of simple but conscious thinking. And especially significant objective data about animal thoughts and feelings are already available, once communicative signals are recognized as evidence of the subjective experiences they often convey to others. The scientific investigation of human consciousness has undergone a renaissance in the 1990s, as exemplified by numerous symposia, books and two new journals. The neural correlates of cognition appear to be basically similar in all central nervous systems. Therefore other species equipped with very similar neurons, synapses, and glia may well be conscious. Simple perceptual and rational conscious thinking may be at least as important for small animals as for those with large enough brains to store extensive libraries of behavioral rules. Perhaps only in “megabrains” is most of the information processing unconscious.

Abstract: This article examines the relations between methods used in both animal work and study and concepts of animal mind. By “animal work” the authors mean humans and animals working together, and by “animal study” they mean the discipline of ethology, especially the emerging area of cognitive ethology. Within these areas the wide range of conceptions of animal mind includes varying emphases on intelligence, forms of rationality and language, cognition, consciousness, and intentionality. The authors' central concern is to elucidate the vocabulary and the concepts which seem necessary to establishing successful working relationships with sheepdogs and gundogs. Their argument moves toward an emphasis on the appreciation of particular intentional states and recognizes that they invariably deploy elements of a moral vocabulary in achieving creative teamwork performances with dogs and other animals. The article concludes by consid enng the relevance of accounts of work with animals for associated considerations of intentionality.
