The overflow debate concerns this following question: does conscious iconic memory have a higher capacity than attention does? In recent years, Ned Block has been invoking empirical works to support the positive answer to this question. The view is called the “rich view” or the “Overflow view”. One central thread of this discussion concerns the nature of iconic memory: for example how rich they are and whether they are conscious. The first section discusses a potential misunderstanding of “visible persistence” in (...) this literature. The second section discusses varieties of attention relevant to this debate. The final section discusses the most prominent alternative interpretation of the Sperling paradigm—the postdiction interpretation—and explains how it can be made compatible with a weaker version of the rich or overflow view.

It is a well-established fact in representationalist cognitive science that concrete concepts influence human perception. In radical, anti-representationalist cognitive science, however, the case is far from clear. One reason for this is that proponents of Radical Enactivism yet have to clarify whether perceptual activity involving concepts is bound to rely on mental content or if it instantiates basic, contentfree cognition. The purpose of this paper is to show that concept-involving perception instantiates REC-style basic cognition. The paper begins by considering ‘cognitive (...) projection’ as the term is introduced by Distributed Cognition research. Although being introduced as a means for exploring concept-based perception in non-representationalist terms, I argue that ‘cognitive projection’ comes with mentalist overtones and unclarities concerning its linguistic basis. With the purpose of overcoming these shortcomings, I unfold a REC-friendly reading of Wittgenstein’s writings on aspect perception, arguing that basic concept-involving perception is an instantiation of basic cognition. Concludingly, with the aim of ensuring compatibility, I make a connection between conceptual aspect perception and the REC notion of attentional anchors. The latter has been introduced to explore the role of material artefacts in the context of science, technology, engineering, and mathematics educational design but has, I submit, the potential for being extended to other practical contexts.

The paper thematizes basic content-free cognition in human social practices. It explores the enlanguaged dimension of skilled practical doings and expertise by taking the minimal case of concept-based perception as its starting point. Having made a case for considering such activity as free of mental content, I argue in favor of the abolishment of the distinction between truth-telling and social consensus, thus questioning the assumption held by proponents of Radical Enactivism, namely that truth and accuracy conditions are restricted to content-involving (...) activity. Instead, I claim, even content-free practical activity can be evaluated on the basis of accuracy conditions which ultimately tie with agents’ practical understandings and the normative aspects of the practice. With this as my backdrop, I explore how expertise arises in the interplay of enlanguaged affordances, concept-involving perception and the normative accuracy conditions that constrain a particular practice.
