Abstract
The phenomenon of synesthesia has undergone an invigoration of research interest and empirical progress over the past decade. Studies investigating the cognitive mechanisms underlying synesthesia have yielded insight into neural processes behind such cognitive operations as attention, memory, spatial phenomenology, and intermodal processes. However, the structural and functional mechanisms underlying synesthesia still remain contentious and hypothetical. The first section of the chapter reviews recent research on grapheme-color synesthesia, one of the most common forms of the condition, and addresses the ongoing debate concerning the role of selective attention in eliciting synesthetic experience. Drawing on conclusions from the first half, the
