The critical role of mental imagery in human emotion: insights from Aphantasia [article]

Marcus Wicken, Rebecca Keogh, Joel Pearson
2019 bioRxiv   pre-print
One proposed function of imagery is to make thoughts more emotionally evocative through sensory simulations. Here we report a novel test of this theory utilizing a special population with no visual imagery: Aphantasia. After using multi-method verification of aphantasia, we show that this condition, but not the general population, is associated with a flat-line physiological response to frightening written, but not perceptual scenarios, supporting the critical role of imagery in human emotion.
