This study investigates associative visual memory in aphantasia, finding intact object and spatial memory, metacognitive awareness, and the use of nonvisual strategies by aphantasics.

This study shows that the pupillary light response correlates with sensory imagery strength and is absent in aphantasia, providing physiological validation of the condition.

The paper shows that lower excitability in early visual cortex predicts stronger mental imagery and that reducing excitability increases imagery strength.

The paper tests the role of mental imagery in emotion using aphantasia, finding that individuals without visual imagery show reduced physiological responses to frightening written scenarios.
