Jihyun has worked on several questions of memory retrieval and encoding. Her thesis, which she just successfully defended focuses on item effects and their potential contamination of the subsequent memory contrast in fMRI. This work demonstrates that behaviorally modeling item selection effects increases the power to detect new regions predictive of encoding, and indicates that the typical regions documented in this work reflect unique interactions between each subject and the to-be-encoded items.
Marina P. Gross
Marina is interested in memory encoding and has just completed a study examining the links between time pressure, depth of processing, and pupil dilation during encoding. Her findings suggest that the efficacy of encoding is not signaled by the pupil during encoding. Instead, the time pressure under which processing occurs appears to be the dominant dilation component.
Lisa's focus has been on pupil dilation during memory retrieval and what it signifies about memorial decision making. Her most recent study suggests that the motivational significance of memoranda is signaled in the degree to which the pupil dilates during memory judgments
David's initial focus has been on the affective consequences of memory decisions. He recently published his honors thesis research demonstrating that successful and failed memory searches trigger subtle positive and negative responses to the memoranda.
