Relationships between Memory Retrieval, Media Multitasking, and Attention: An EEG/Pupillometry Approach
Abstract/Contents
- Abstract
- When an individual retrieves a memory, trial-level fluctuations between attention lapses, and memory may interact with subject-level differences in constructs such as media multitasking and sustained attention. I will present data and reflections on my master’s research project that lend support to this theoretical framework. Concurrent EEG+pupillometry was recorded during an encoding/retrieval task with 80 young adults to examine how (a) multimodal trial-level indices of attention lapsing relate to goal coding and memory, and how (b) trait differences in self-reported media multitasking and task-based sustained attention may contribute to these interactions. Pre-trial lapses of attention as recorded by tonic changes in alpha and theta oscillatory power and pupil diameter predicted retrieval accuracy; decreases in pupil diameter and theta power and increases in alpha – assays of lapsing – predicted retrieval misses vs. hits. Subject-level increases in media multitasking were related to decreases in sustained attention and retrieval accuracy using continuous and extreme group approaches. These results suggest that trial-level interactions in attention-control-memory and subject-level differences in media multitasking and sustained attention may help explain how an individual remembers.
