In his paper, in this journal, Sterelney claims that cases of extended mind are limiting cases of environmental scaffolding and that a niche construction model is a more helpful, general framework for understanding human action. He further claims that extended mind cases fit into a corner of a 3D space of environmental scaffolds of cognitive competence. He identifies three dimensions which determine where a resource fits into this space and suggests that extended mind models seem plausible when a resource is (...) highly reliable, individualised/entrenched and a single-user resource. Sterelney also claims that the most important cognition-enhancing resources are provided collectively by one generation to the next. In this paper, I argue that Sterelney is both right and wrong and this because he focuses primarily on external, physical resources and construes scaffolding as exclusively unidirectional and diachronic. Using examples of unfamiliar tool use, visual processing and human emotional ontogenesis, I argue, respectively, that extended mind cases include those which fail to meet Sterelney’s dimensional criteria; that the most important cognition—enhancing resources are those which actually build brains; that these are provided on a one-to-one basis in emotional ontogenesis; and, this depends on bidirectional and synchronic cognitive scaffolding.

Contingent transcranialists claim that the physical mechanisms of mind are not exclusively intracranial and that genuine cognitive systems can extend into cognizers' physical and socio-cultural environments. They further claim that extended cognitive systems must include the deep functional integration of external environmental resources with internal neural resources. They have found it difficult, however, to explicate the precise nature of such deep functional integration and provide compelling examples of it. Contingent intracranialists deny that extracranial resources can be components of genuine extended (...) cognitive systems. They claim that transcranialists fallaciously conflate coupling with constitution and construe cognition as extending always from brains into world rather than world into brains. By using insights from recent research in developmental psychology and by explicating the nature of one form that deep functional integration can take, I argue that (i) transcranialists do not fallaciously conflate coupling wth constitution, and (ii) human emotional ontogenesis is a world-to-brain transcranial achievement.
