Within the depth-psychology corpus, cognition resists reduction to a single, settled meaning; it is instead a contested site where neuroscience, phenomenology, embodied philosophy, and clinical practice converge and strain against one another. Thompson’s enactive account, drawing on Maturana and Varela, defines cognition as the activity of sense-making rooted in autopoiesis — not information processing on the computational model, but skillful, embodied know-how enacted through sensorimotor coupling with a world. This stands in productive tension with the classical cognitive-science paradigm that Thompson himself critiques: the computer model of mind, which treated cognition as symbol manipulation in a disembodied, cultureless system. McGilchrist complicates matters further by insisting that perception — and therefore cognition — is grounded in motility, activity prior to and constitutive of perception itself. In the clinical register, Ogden and Shapiro treat cognition as one processing level among three (sensorimotor, emotional, cognitive), one that trauma can dysregulate, and that EMDR targets through the installation of adaptive positive and negative cognitions. Jaynes, characteristically contrarian, argues that the actual process of thought is not conscious at all, that cognition proceeds invisibly and presents only its results to awareness. Together these voices reveal a field in which cognition is variously embodied, enacted, hierarchically layered, neurobiologically grounded, and therapeutically manipulable — never simply the rational deliberation of an autonomous Cartesian mind.
