1 Critical Note Tobias Schlicht To appear in: Oxford Handbook of 4E cognition, ed. by A. Newen, S. Gallagher, L. de Bruin. OUP (commentary on papers by Froese, Hohwy, Lamb & Chemero, and Menary on 4E perspectives) Abstract This commentary is structured according to the following discussion points: (1) the compatibility of the recently popular predictive processing framework with 4E approaches, (2) the possible constraints that phenomenological characterizations of cognitive phenomena put on modeling and experimentation, illustrated by the debate on social cognition, (3) the putative replacement of the classical representationalist approach to cognition by a rigorously dynamic and embodied approach to cognition, and (4) the contrast between brainbound and extended or integrated cognitive systems.
