New Information/Draft Benchmarks

7 children5/7 identified by newborn screening– aided 2-6 months

Other 2 aided at 6 months and 11 monthsImplanted between the ages of 10-14 monthsAll received parent educationAll received/ing early intervention – at least 2 times per week– 1 hour individual therapy– 2 ½ hours group instruction

Comparison of Information

Children implanted around age 2

Children implanted around age 1

Almost Immediately After Activation

Detection of sound– both groups– parents report observing

Detects Ling 6 sounds– older children may demonstrate

with behavioral activities– younger group will demonstrate by observation

Detects environmental sounds– parents report observing

0-4 Months Post Activation

A “listening” time

4-6 Months Post Activation

Children implanted around age 2 – identify 35 to 50 words– produce about 75% of those words prompted– use single words spontaneously

Children implanted around age 1– begin to demonstrate comprehension

about 9-11 months post activation (21-23 months old)– identify 20-50 words, in sets of three– produce up to 25% of those words prompted

1 Year Post Activation

Children implanted around age 2 (3 years old)– identify 75-100 words– produces 50%-75%– understand and produce some

early developing two-word combinations– use single words, common phrases and expressions

spontaneously

Children implanted around age 1 (2 years old, data on 4)– identify 100-125 words– produce 25%-50%

15-18 Months Post Activation Children implanted around age 2 (3 ½ years old)– a language explosion seems to occur– vocabulary is learned in a variety of environments– vocabulary increases to more than 250 words– comprehension of simple three- and four- word sentences– use a variety of two-word combinations spontaneously

Children implanted around age 1 (2 ½ years old)– vocabulary increases to 270-485 (data on 4)– produce greater than 60% of vocabulary prompted– understand and produce word combinations in a variety

of settings

2 Years Post ActivationChildren implanted around age 2 (4 years old)– vocabulary of more than 500 words– comprehension of a variety of simple sentences and questions– use simple sentences of 4-6 words spontaneously

Children implanted around age 1 (3 years old,data on 4)– similar comprehension

• 390- more than 500 words• understands a variety of simple sentences and early-

developing questions

– production similar or slightly less• produce at least 75% of vocabulary words• produce word combinations spontaneously
