Strategic Flexibility and Age-Related Cognitive Change

Barulli, Daniel James January 2019 (has links)
This series of projects aims to explore the potential role of strategic flexibility in cognitive aging, and whether this construct can serve as an effective mechanistic proxy for cognitive reserve. Study 1 introduces the task designed for this series, based on stimuli from a classic test of fluid reasoning and formatted as a task-switching paradigm to explore strategic characteristics in a structured way. This study suggests that such a task is subject to age-related effects. Study 2 introduces a redesigned version of this task, matching it more closely to existing paradigms of task-switching, and explores how covariates interact with measured performance. Study 3 draws upon an existing sample of extensive neuropsychological and neuroimaging data, and aims to describe the associations among this set of data and measures of strategic flexibility. Results overall indicate that age negatively affects strategic flexibility, but cognitive reserve may mitigate this impairment.

Problem Solving Cognitive Processes in Younger and Older Adults

McGregor, Patricia A. (Patricia Ann) 12 1900 (has links)
The purpose of the present study was to examine cognitive abilities and problem solving processes of young and older adults. Specifically, three areas of inquiry were investigated: possible age-related differences in problem solving cognitive abilities, possible differences in cognitive processes used during problem solution, and possible differences in determinants of problem solving cognitive processes.

Learned Attention in Younger and Older Adults

Holder, Jared M. 01 December 2010 (has links)
A relatively new phenomenon in learning research called highlighting occurs when participants show a seemingly irrational preference to attribute a stronger cue-outcome association to a later presented perfect predictor when it is paired with an imperfect predictor than that of an earlier presented perfect predictor paired with the same imperfect predictor (Kruschke, 1996). Current research suggests that the highlighting effect depends on the ability to learn to shift attention away from an irrelevant cue toward a more relevant cue in order to reduce errors in causal judgment and preserve an earlier formed association (Kruschke, 2003). Much research has suggested that older adults have difficulty disengaging attention from irrelevant information, which could be problematic in the highlighting procedure (Cohn, Dustman, & Bradford, 1984; Tipper, 1991; Mutter, Naylor, & Patterson, 2005). However, the results of the current experiment suggest that older adults can learn attentional shifts in order to guide associative learning and reduce errors in causal judgments. These data prove to be a problem for many models of associative learning (e.g., Mackintosh, 1975; Rescorla & Wagner, 1972; Van Hamme & Wasserman, 1994), but support a model proposed by Kruschke (2006).
