In a world where sensory threads weave an endless tapestry of multi-modal data, the human brain stands as the masterful weaver of meaning. As we wade through this tempest of input, our brain spins these threads into an intelligible internal representation and holds on tight to what it deems important. But what, exactly, makes certain threads more important than others? And how can we predict their significance? Memorability is the tensile strength of the threads that tie us to the world. It is a proxy for human importance, indicating which threads the human brain will curate and retain with exceptional fidelity. This research investigates these multisensory threads by exploring the influence of audio, visual, and textual modalities on predicting video memorability, and how the interplay between them can influence the overall memorability of a given piece of content. The findings suggest that, while visual data may dominate our sensory experience, it is the underlying conceptual essence that truly holds the key to memorability. This thesis leverages state-of-the-art image synthesis techniques to distill and examine this essence, creating surrogate dreams of video scenes to facilitate the disentanglement of conceptual and perceptual elements of memorability. The work also leverages human EEG data to explore the possibility of a moment of memorability—a moment of encoding that corresponds to a remembering moment—which we expect to exist due to the temporal nature of the world and the natural encoding limits of our brains. The previously murky relationship between the two core means of remembrance---recognition and recall---are reconciled by conducting a novel video memorability drawing task. The research sheds new light on the nature of multi-modal memorability, providing a deeper understanding of how our brain processes and retains information in a complex sensory world. By uncovering the conceptual essence that lies at the heart of memorability, it opens up new avenues for predicting and curating more meaningful media content, and ultimately deepen our connection to the world around us.
