Visual imagery typically enables us to see absent items in the mind's eye. It plays a role in memory, day-dreaming and creativity. Since coining the terms aphantasia and hyperphantasia to describe the absence and abundance of visual imagery, Adam Zeman and his team have been contacted by many thousands of people with extreme imagery abilities. Through data collected from questionnaires filled by 2000 participants with aphantasia and 200 with hyperphantasia, the researchers have found some interesting patterns. Participants with aphantasia tend to work in scientific and mathematical fields and have difficulty with face recognition and autobiographical memory. On the other hand, those with hyperphantasia tend to work in creative fields and have a higher rate of synaesthesia. The study found that around half of the participants with aphantasia reported the absence of wakeful imagery in all sense modalities, but most of them dream visually. The researchers have also noted that aphantasia runs in families more frequently than expected. This study highlights the widespread but neglected features of human experience with informative psychological associations.
