![]() ![]() As the form memory task was found to be an invalid indicator of eidetic ability, more research is still needed to establish an objective measure of eidetic ability. Performance on the form memory task was highly related to IQ, and measures of reading ability, but was not related to sex or school attended. (1933) Eidetic phenomena in Negro school children. Appendix: Individual research on adults). (Research on eidetic abilities in a girls high school. Performance on the picture description task was not found to be significantly related to sex, school, IQ, or measures of reading ability. The inside and outside of eidetic imagery - Volume 2 Issue 4. The major findings indicated that the relationship between performance on the picture description and form memory task were insignificant, making the form memory task an invalid indicator of eidetic ability, and thus indicating that Zelhart and Johnson (1959) were measuring memory ability. Standardized IQ and reading ability scores, as well as teacher ratings of reading ability were also obtained for each subject. Here an attempt was made to validate the form memory task as an eidetic indicator. An eidetic person claims to continue to ‘see’ an object that is no longer objectively present. ![]() At the upper extreme end there are individuals with eidetic imagery who report strongly evoked mental images with an almost veridical quality. The most cited scientist in the field, Ralph Norman Haber, in 1979 summarized all the studies made up until that point on this elusive subject in a fascinating research paper titled Twenty years of haunting eidetic imagery: where’s the ghost. A major assumption underlying the Zelhart and Johnson (1959) study was that the form memory task could be used as an indicator of eidetic ability. Eidetic imagery, an unusually vivid subjective visual phenomenon. Visual imagerythe mental construction of a scene-like objectis known to vary across individuals (e.g., Marks, 1973). An independent sample of 56 third graders (28 girls and 28 boys) from two different schools were tested for eidetic ability on a picture description task and also completed a form memory task developed by Zelhart and Johnson (1959). ![]() Fifty-nine third graders (34 boys and 25 girls) participated in determining the association values of certain shapes. This study explored the possible relationships between eidetic imagery, memory for shapes, IQ, and reading ability. ![]()
