What Might Cognition Be, If Not Computation?

structure of the target phenomenon, for various reasons researchers in this approach standardly provide a concrete model: an actual computer programmed so that (hopefully) it realizes the same (or a relevantly similar) abstract computational system as is realized by the cognitive systems under study. If the concrete model appears able to perform actual cognitive tasks in much the way people do,...

A parallel decrease in our so-called intrinsic heart rate, measured in th...
