In a cross-sectional study, we examined age-related differences in visuo-spatial ability associated with image rotation, using two variants of Piaget's 'Three-Mountain Task.' The object-mental rotation (OMR) task detects the ability to mentally rotate an image, whereas the subject-mental rotation (SMR) task reveals the ability to mentally change one's perspective. A group of 33 young adults, 26 middle-aged adults, and 31 elderly normal adults were studied. Both tasks revealed age-related… CONTINUE READING
