Philosophical interest in situated cognition has been focused most intensely on the claim that human cognitive processes extend from the brain into the tools humans use. Coupling arguments are far and away the primary sort of argument given in support of transcranialism. What is common to these arguments is a tacit move from the observation that process X is in some way causally connected (coupled) to a cognitive process Y to the conclusion that X is part of the cognitive process Y. Transcranialism is regularly backed by some form of coupling-constitution fallacy and that it does not have an adequate account of the difference between the cognitive and the noncognitive. A more nagging worry is the motivation for transcranialism. The difference explains why even transcranialists maintain that cognition extends from brains into the extraorganismal world rather than from the extraorganismal world into brains.
