Attention and Speed of Information Processing

摘要: Theoretical models suggest the existence of at least three relatively independent attentional mechanisms implemented in partially segregated brain networks: vigilance, orienting, and executive attention. In this article, we review tasks for assessment, related neuroanatomy, impairments these mechanisms. We also exemplify how networks interact daily life activities an efficient adjustment to environmental demands, they can be hindered after different pathological states, such as acquired injury, degenerative diseases, developmental changes (in child aging process). Finally, importance speed information processing a key modulator appropriate functioning is discussed.
