BPVS

BPVS 3• Norm referenced test of receptive vocabulary

Summary• Children with simultaneous implants “catch up”

with the older sequentially implanted children who have had more hearing experience in functional listening

• At 3 years post implantation the simultaneously implanted children acquire fairly intelligible speech
