Imagery Spectrum in Minds

Research reveals a spectrum of mental imagery abilities, from those who can vividly visualize detailed scenarios like flying on a Pegasus to those with aphantasia who experience no visual imagination. This spectrum impacts perception, emotions, and even potential cognitive disorders such as aphantasia or hyperphantasia. Strong imagery can lead to heightened emotional responses, challenges in distinguishing reality from imagination, and interactions with traumatic memories or anxieties.
