an apparatus for testing aspects of how a child learns includes a toy - like base having upstanding pegs . the child is encouraged to place donut shaped hand pieces onto the pegs . the hand pieces test the ability of the child to discriminate between different colors , and separately between different textures and different shapes and also tests the child &# 39 ; s abilities in perception and creativity . the base also is able to test the child &# 39 ; s ability to discern and copy tones and rhythms . information of the child &# 39 ; s performance is automatically collected within the apparatus and then compared with a normative baseline . remediation focuses on activities related to the learning channels where the child is least astute and periodic retesting measures the ability of the child to improve in those channels to enable improvement of remediation approaches .
