Psychology diffuson model aging recognition source sentence processing Many studies examining the effects of aging on memory and sentence processing rely on a single dependent variable to generate their conclusions: either accuracy or response time. The conclusions derived from analysis of a single variable often stand in direct opposition to one another, with studies using response time frequently finding universal cognitive deficits and studies using accuracy finding task-dependent deficits. The diffusion model (Ratcliff, 1978) provides a method to analyze both variables in an integrated manner in order to meaningfully separate components of processing. These components of processing can then be compared across age groups to determine where and if age-related deficits exist. We apply the diffusion model to data from three experiments with young and older adults using sentences as the stimuli. Relative to young adults, older adults show improved memory for facts in general knowledge, comparable recognition memory, and a deficit in source memory for sentences. The importance of analyzing both response time and accuracy data is discussed. 2009-06-26 English text The Ohio State University / OhioLINK http://rave.ohiolink.edu/etdc/view?acc_num=osu1238100645 http://rave.ohiolink.edu/etdc/view?acc_num=osu1238100645 unrestricted This thesis or dissertation is protected by copyright: all rights reserved.
