Memories in the Making: Predicting Video Memorability with Encoding Phase EEG
This work addresses the problem of understanding and predicting memory formation for video content, which is incremental as it builds on existing EEG and deep learning methods.
The study tackled predicting video memorability by analyzing encoding phase EEG signals, finding that theta band oscillations in the right temporal lobe are involved and supporting the existence of a distinct memorability moment.
In a world of ephemeral moments, our brain diligently sieves through a cascade of experiences, like a skilled gold prospector searching for precious nuggets amidst the river's relentless flow. This study delves into the elusive "moment of memorability" -- a fleeting, yet vital instant where experiences are prioritised for consolidation in our memory. By transforming subjects' encoding phase electroencephalography (EEG) signals into the visual domain using scaleograms and leveraging deep learning techniques, we investigate the neural signatures that underpin this moment, with the aim of predicting subject-specific recognition of video. Our findings not only support the involvement of theta band (4-8Hz) oscillations over the right temporal lobe in the encoding of declarative memory, but also support the existence of a distinct moment of memorability, akin to the gold nuggets that define our personal river of experiences.
