Role of Visual Attention in Developmental Dyslexia

Attention is a neurocognitive process composed by subprocesses located in several brain areas and controlled by specific neurotransmitters (Petersen & Posner, 2012). This process aims to select relevant information and modulates sensory processing, perception, memory, and learning. This selection of information processing – based on the combination of perceptual noise exclusion and signal enhancement – is fundamental in developing fine object representations in the brain (see Corbetta & Shulman, 2011; Petersen & Posner, 2012; Roelfsema, van Ooyen, & Watanabe, 2010, for reviews).
