| Abstract: | Partially replicated M. Parrish, R. Lundy, and the Liebowtiz's (see record 1970-03085-001) study on the effect of hypnotic age regression on the magnitude of the Ponzo and Poggendorff illusions. The Ponzo illusion was presented to 4 male and 4 female undergraduates under 3 conditions: waking, regressed to age 9, and regressed to age 5. Unlike the previous study, there were no significant difference in the magnitude of the illusion across the 3 conditions. It is concluded that hypnotic age regression does not affect the magnitude of the Ponzo illusion. It is suggested that age regression is a questionable tool for investigating developmental aspects of perception. (27 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved) |
