Abstract and Keywords
Selective attention is a process by which the brain enhances its representation of task relevant, over irrelevant information. This ‘active control’ is essential to normal perception and cognition because it enables information processing to adapt to the immediate goals of the observer. This chapter places the focuses on recent conceptual/empirical developments in four areas that the authors think have significantly advanced the discussion and debate on the mechanistic underpinnings of selective attention: (1) the role of neuronal oscillations, (2) the distinctions between differing modes of dynamic operation, (3) potentially unique roles of specific oscillatory frequencies, (4) the neurochemistry of attention. The authors end by replacing attention within an ‘active sensing’ framework, and posing a set of prime questions for future study.
