We trace how cognition arises beyond the skin. Experimental work on insight problem solving is used to examine how external artifacts can be used to reach the goal of assembling a `cheap necklace'. Instead of asking how insight occurs `in the head', our participants in Experiment 1 can either draw solution attempts or manipulate real objects . Even though performance with real chain links is significantly more successful than on paper, access to objects does not make this insight problem simple: (...) objects themselves do not shape cognition. This challenges extended mind views. While failure often results from the inappropriate application of hill-climbing, material artifacts can trigger solutions. In Experiment 2, we used `open link' conditions of the concretized problem to prompt participants to act . Solutions arrived via insight, serendipity, or trial-and-error. By investigating how objects are used, we show that they do more than supplement neural events. Rather, participants monitor and anticipate the effects of action within an organism-environment system. By analogy, language too draws on experience of monitoring real-time effects as bodily dynamics play out in a normative and cultural world. In engaging with public language, it is likely that verbal patterns function by constraining anticipatory cognitive processes. (shrink)

Differences in difficulty between isomorphs of the Tower of Hanoi are generally explained in terms of differences in processing loads required by the different versions Kotovsky & Fallside, 1989 . Our claim is that the general knowledge about an action, activated by the context, is what guides the elaboration of problem representation. To test this hypothesis, we manipulated the context using four isomorphs. The results support the hypothesis: the selection of the adequate point of view on the action depends on (...) the context, and is a crucial step in the elaboration of problem representation. The more difficult versions are those that require abandoning the first point of view and selecting a new one. (shrink)

In 1890 Christian von Ehrenfels published his classic paper "Über 'Gestaltqualitäten'", the first systematic investigation of the philosophy and psychology of Gestalt. Ehrenfels thereby issued an important challenge to the psychological atomism that was still predominant in his day. His paper not only exerted a powerful influence on the philosophy of the Meinong school, it also marked the beginning of the Gestalt tradition in psychology, later associated with the work of Wertheimer, Köhler and Koffka in Berlin. Includes papers by C. (...) Von Ehrenfels, Kurt Grelling and Paul Oppenheim and contributions by K. Mulligan, P.M. Simons and Barry Smith. (shrink)
