is used to visually entice the child into a play situation, using visual contrast, color, motion and tactile reinforcement. "Heidi" determines the "visual sphere", which is the distance within which the child visually responds. Complete testing within child's visual sphere. "Heidi" is a stuffed, cloth doll designed for simplicity by Dr. Hyvärinen. The body is white with a black border and embroidered face so child can gain visual and tactile stimulation. The "HEIDI" DOLL is used to introduce the child to "Heidi" in a play situation such as peek-a-boo and establish rapport so testing can continue with the other "Heidi" assessment materials.

#A251600 The 3-D Puzzle

is used to familiarize the child with LEA Symbols before testing. Perceptual information is gained by simultaneously looking at and feeling the Symbols. Present smaller Symbols on the cards to assess acuity. There are removable 2" black and white symbols within a white form board. When the form board and Symbols are turned over the child can match colored Symbols on the green side. Non-verbal children respond to acuity tests by touching the matching Symbols, and also learn object/picture relationships.

The sound of milk motivates the baby to try to locate the bottle, so pair auditory with visual stimulation to encourage meaningful vision.
