title: From cognitive neuroscience to geriatric neuropsychology: what do current conceptualizations of the action error handling process mean for older adults?
abstract: The fields of cognitive neuroscience and neuropsychology have contributed an extensive corpus of research to the study of error monitoring processes in younger adults; however, less is known about error handling in older adults. This paper highlights current conceptualizations of error detection and correction in healthy and impaired older adult populations. The literature suggests that some error handling processes require fewer processing resources than others and may be performed relatively automatically. Compared with young adults, older adults demonstrate a reduced ability to recognize errors, but exhibit similar rates of correction. Older adults diagnosed with a neurodegenerative disease (e.g. Alzheimer's disease) show a reduced ability to detect and correct their action errors. Thus, neurodegenerative disease processes amplify the impairments in error identification associated with normal aging by disrupting both automatic and controlled error corrections. The clinical implications of our current knowledge are discussed, and directions for future neuropsychological research are offered.
