Eidetic imagery: longitudinal results in brain-damaged children.

There have only been a few attempts to assess whether eidetic imagery is inversely related to age. A sample of 15 known eidetikers from a previous study, having particular forms of brain damage, were retested after a lapse of 20 months. The hypothesis of the study was that older children are most likely to lose their capacity for seeing eidetic images over a period of 20 months than are younger children. The data confirmed the hypothesis and was interpreted as supporting the theory that eidetic imagery is a developmental process that decreases in importance over the course of a child's development.
