PDM is likewise foundational to everyday functioning across a variety of contexts, making it an important and popular area of cognitive research. One approach is to view the process as a series of three steps: 1) intake and processing of sensory stimuli from the environment, 2) amassing of evidence towards or away from opposing choices, and 3) finalizing one\u2019s choice selection. This framework is conceptually supported by an extensive body of human and non-human primate literature that spans several decades. One critical example is a series of findings that suggest these stages are discernable at the neural level because each is associated with specific brain regions. This conclusion is based on a complex review of younger adult BOLD timecourse profiles collected via functional magnetic resonance imaging during an object identification PDM task. However, despite this useful insight, it is unclear if or how the same results will hold for older adult brains that are likely experiencing numerous age-related functional and structural changes, particularly cortical\/hemispheric dedifferentiation and global age-related changes to the central nervous system. This lack of understanding makes the results of PDM aging experiments difficult to interpret from a hierarchal perspective. The goal of the current work is to address that lingering uncertainty. This will be accomplished by comparing the physical and temporal properties of older and younger adults\u2019 BOLD timeseries data on a stage-by-stage basis, hierarchal clustering, and an exploratory dedifferentiation analysis. \u0026nbsp;\u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/p\u003E\r\n","summary":"","format":"limited_html"}],"field_subtitle":"","field_summary":[{"value":"\u003Cp\u003E\u003Cstrong\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cspan\u003E:\u0026nbsp;\u003C\/span\u003E\u003C\/span\u003E\u003C\/span\u003E\u003C\/strong\u003E\u003Cstrong\u003E\u003Cspan\u003E\u003Cspan\u003E\u003Cspan\u003EHow does a current perceptual decision-making model carry forward to older adult samples?
