Suggested materials to use in Assessment for Range 3-4
Color
Has “preferred” color
Movement
More consistent localization, brief fixations on movement and reflective materials
Visual latency
“Wait time” may decrease after periods of consistent viewing
Continue to document “wait time” to share with the child’s Team
Visual field preferences
Shows visual field preferences
Observe, observe and interview those who know the child best
Complexity
Visually fixates when environment is controlled (single color objects without additional sensory input)
Continue to be aware of the child’s best environment for vision: block out visual clutter, limit talking/music, strong smells
Shows little or no visual attention to human faces, little or no eye contact
Light
Less attracted to lights
Can be redirected to other targets
Highlight objects by shining a flashlight onto the toy
Block light from being the focus, making the desired target (rather than light itself) the point of visual interest
Distance viewing
Occasional visual attention to familiar, moving or large targets at 2 to 3 feet
Atypical visual reflexes
Blinks in response to touch, but response may be latent
Novelty
May tolerate novel objects if the novel objects share characteristics of familiar objects
Share single preferred color
Share movement and single color
Absence of visually guided reach
Look and touch occur with smaller objects that are familiar, lighted or reflective
Look and touch are still separate
