2. 1. Seat the infant on a familiar adult’s lap, so that the in
fant is comfortable.
2. Select a small toy or other attention-attracting object
that stimulates sight only;
do not use a sound-producing object. Hold the object a
bout 1 to 2 feet from
the infant’s face and move it horizontally to either side.
3. Watch the infant’s eyes for fixation and following mo
vements
3. 4. Cover one eye and repeat the test. Cover the other eye
and repeat again. Observe for any difference between th
e eyes in the quality of fixation and smooth pursuit or in
the amount of objection to occlusion. If you suspect a diff
erence but are unsure, repeat these tests, using a differe
nt toy if available to maintain the infant’s interest.
4. 5. When tested monocularly, very young infants will respond wit
h better follow-ing movements for objects moved from temporal
to nasal field; this preference decreases after an infant is approxi
mately 6 months old.
