Ian M. McDonough is an Associate Professor of Psychology at The University of Alabama, Tuscaloosa, Alabama, United States. He is interested in the encoding and retrieval mechanisms of episodic memory, especially how people use decision processes to determine the accuracy of the retrieved information and how these processes differ in old age. To better understand the mechanisms underlying these processes, he uses a variety of different techniques including experimental manipulations of behavior, neuropsychological tests, and both structural and functional brain imaging. More recently, he has been interested in how random, or entropic, fluctuations of brain activity might serve as a neural marker of cognitive and brain health.
