Most people can create pictures in their minds eye, for example of an apple, or a friend’s face, but some people find this very hard, or even impossible. It is this latter group of people that have aphantasia.
Children with aphantasia may not understand instructions or exercises that involve creating pictures in their minds eye. They might need to draw things out to process or understand visual information that most children will be able to do in their minds eye. There’s no research on children with aphantasia yet as is the field is still emerging but findings in adults suggest that children with aphantasia may have difficulty in remembering life events clearly, or recognising people’s faces.
