| Outline of Final Research Achievements |
This study aimed to clarify how children with congenital limb paralysis or deficiencies perceive visually their bodies, particularly their limbs. Participants were children with spina bifida, congenital limb deficiencies, and control children. We examined (1) self-portraits (visual cognition), (2) body part labels (verbal cognition) and (3) eye-tracking (visual inputs).
There were no significant differences in visual inputs between spina bifida children and control children; however their visual and verbal cognition of feet and hands, which is homologous organ with feet, were significantly lower than those of control children. While children with congenital lower limb deficiencies visually cognize their artificial limbs as their limbs, children with upper limb deficiencies had lower visual cognition of their limbs than did control children. Both children with upper and lower limb deficiencies had significantly lower verbal cognition of limbs.
