The study of spatial cognition has greatly attracted the attention of researchers since last few decades. Spatial categorization was viewed simply as a reflection of a deep- seated properties of human perceptual and cognitive organization (Piaget, 1954). Piagetian tradition suggests that child's knowledge progresses through three different development stages consisting of an egocentric stage, allocentric stage and a geocentric stage. These stages represent the sensorimotor, pre-operation, concrete operation and formal operation. At each stage certain cognitive structures emerge that incorporate the previous structures, which are invariant manner, taking into account only it's point of view. "Perspective taking", projective and Euclidean spatial concepts develop later on. | Development of spatial cognition in mountainous and plane nepalese children
