Debates in 4E and scaffolded cognition have been centered on cases in which human cognitive or affective capacities are enhanced through technology. Recently some authors have noted that this may not always be the case: the technologies and environment around us can negatively impact cognitive and affective abilities. In the first part, I elaborate on this change of perspective in the debate. In the second part, I discuss a case of technology scaffolding maladaptive psychological processes. More in detail, I will (...) focus on the role of smartphones in scaffolding ruminative processes. To illustrate this claim, I introduce four core features of rumination and discuss how they may be supported by problematic smartphone use in light of existing evidence. (shrink)
