Catching Ourselves in the Act uses situated robotics, ethology, and developmental psychology to erect a new framework for explaining human behavior. Rejecting the cognitive science orthodoxy that formal task-descriptions and their implementation are fundamental to an explanation of mind, Horst Hendriks-Jansen argues for an alternative model based on the notion of interactive emergence. Situated activity and interactive emergence are concepts that derive from the new discipline of autonomous agent research. Hendriks-Jansen puts these notions on a firm philosophical basis and uses them to anchor a "genetic" or "historical" explanation of mental phenomena in species-typical activity patterns that have been selected by a cultural environment of artifacts, language, and intentional scaffolding by adults. Situated robotics, allied with techniques and principles from ethology, allows the testing of hypotheses framed in terms of natural kinds that can be grounded through the theory of natural selection. This approach negotiates the "nature versus nurture" dispute in a radically new way. Catching Ourselves in the Act provides a thorough overview of autonomous agent research in America and Europe, focusing in particular on work by such eminent researchers as Rodney Brooks, Pattie Maes, Maja Mataric, and Rolf Pfeifer. It reassesses the basic principles of artificial life and explores the repercussions of autonomous agent research for human psychology and the philosophy of mind, as well as its affinities with the "contextual revolution" in sociology and anthropology.
