Determinants of visual ambiguity resolution

Published in Communications Psychology, 2026

Analyzing over 100,000 human ratings of ambiguous images, this study shows that ambiguity resolution relies primarily on high-level visual features, with the visual system shifting from top-down guessing to bottom-up matching after disambiguation.

Schema-driven prediction effects on episodic memory across the lifespan

Published in Philosophical Transactions of the Royal Society B: Biological Sciences, 2024

This study uses visual narratives to show that schema-driven predictions shape episodic memory through two complementary mechanisms — schema integration and prediction-error-driven encoding — across childhood, adulthood, and old age.

Feedback signals in visual cortex during episodic and schematic memory retrieval and their potential implications for aphantasia

Published in Neuroscience and Biobehavioral Reviews, 2023

This study explores how feedback signals from episodic and schematic memory retrieval travel through the visual cortex, with implications for understanding memory deficits in aphantasia.

Not What U Expect: Effects of Prediction Errors on Item Memory

Published in Journal of Experimental Psychology: General, 2023

This study investigates how prediction errors impact item memory, revealing an inverted U-shape function with better memory performance for intermediate levels of prediction error.
