title: Piaget's water-level task: the impact of vision on performance.
abstract: In the present study, the aim was to examine the differences in performance between children and adolescents with visual impairment and sighted peers in the water-level task. Twenty-eight individuals with visual impairments, 14 individuals with blindness and 14 individuals with low vision, and 28 sighted individuals participated in the present study. Fourteen sighted individuals participated blindfolded and 14 were able to use their sight. The findings indicate that use of vision can influence the performance in water-level task. However, in the restriction of visual ability (participants with blindfold), individuals with blindness might present better performance than blindfolded sighted participants.
