The maps problem and the mapping problem: two challenges for a cognitive neuroscience of speech and language.

摘要: Research on the brain basis of speech and language faces theoretical empirical challenges. Most current research, dominated by imaging, deficit-lesion, electrophysiological techniques, seeks to identify regions that underpin aspects processing such as phonology, syntax, or semantics. The emphasis lies localization spatial characterization function. first part paper deals with a practical challenge arises in context research programme. This maps problem concerns extent which information can satisfy explanatory needs for perception cognition. Several areas investigation exemplify how neural is discussed those terms (regions, streams, hemispheres, networks). second turns more troublesome challenge, namely formulate formal links between neurobiology principled thus addresses relation primitives cognition (here speech, language) neurobiology. Dealing this mapping invites development linking hypotheses domains. cognitive sciences provide granular, theoretically motivated claims about structure various domains (the “cognome”); neurobiology, similarly, provides list available structures. However, connections will require crafting computationally explicit at right level abstraction. For both problem, developmental approaches evidence play central role resolution.
