Nicole Long is an Assistant Professor of Psychology at the University of Virginia's College of Arts & Sciences, where she leads the Long Term Memory Lab located in Gilmer Hall (Office 404). Her research focuses on understanding the neural mechanisms underlying memory encoding and retrieval processes using advanced neuroimaging techniques including scalp electroencephalography (EEG) and functional magnetic resonance imaging (fMRI).
Dr. Long's research program investigates how strategic, goal-directed processes form and retrieve memories. Her work specifically examines:
- How global brain states and organizational strategies support successful memory formation and retrieval
- The impact of semantic processing on encoding
- How memory brain states influence cognition
- The neural mechanisms that allow us to organize our experiences along semantic, spatial, and temporal dimensions
The Long Term Memory Lab employs multi-modal recording approaches to understand the spatiotemporal dynamics of cognition. While participants perform behavioral tasks, the lab records either scalp EEG activity (providing millisecond-level temporal resolution) or collects fMRI data (providing detailed spatial mapping). The lab utilizes various analytical methods including univariate analyses of spectral components, measurement of correlated activity between brain regions, and multivariate machine learning approaches to decode distributed information across the brain.
Dr. Long's recent publications demonstrate a strong focus on memory brain states, with particular emphasis on how top-down task goals induce retrieval states and how these states interact with attentional processes. Her work bridges cognitive psychology with neuroscience, examining both temporal dynamics (through EEG) and spatial organization (through fMRI) of memory processes. A recurring theme across her research is investigating how organizational processes facilitate memory performance and how these are represented in the brain, with recent work exploring how mnemonic brain states are affected by healthy aging and how semantic associations restore neural encoding mechanisms.
The Long Term Memory Lab actively engages in cutting-edge research with significant contributions to understanding the spatiotemporal dynamics of memory encoding and retrieval states. The lab's multi-method approach provides comprehensive insights into the complex neural architecture supporting human memory, with implications for understanding both typical and atypical memory function across the lifespan.
