Abstract

Spatial ability is a collection of cognitive skills which are responsible for the performance of the individual in different walks of life. In spatial ability, Distance Estimation skill is important for the visually impaired persons. Distance Estimation is crucial for judgment of size, weight, and approximately calculates the distance. Distance is a numerical description of how far and near apart from the objects. It helps visually impaired persons to walk through environment judging the distance. A study was conducted among visually impaired students and blindfolded sighted students to examine the distance estimation ability. Here, in this study visually impaired students were considered as Experimental group and blindfolded sighted as Control group.

The main objective of the study was to find out the impact of intervention on developing distance estimation skill.
