In daily life, we often ascribe value to information based on perceptual or conceptual features, but few, if any, studies have directly examined how such features affect value-directed strategic processing. Additionally, although there is emerging work on the structural and functional bases of value-directed strategic processing, no studies have examined the underlying neurophysiological mechanisms which could provide insights into how value-directed strategic processing neurally unfolds. This dissertation investigates the behavioral and neural effects of perceptually and conceptually defined value on value-directed strategic processing in cognitively normal younger and older adults, and older adults with mild cognitive impairment. Chapter 1 reviews historical perspectives and paradigms related to selective attention and behavioral and neuroimaging literature related to value-directed strategic processing.
