Study: Toddlers with cochlear implants experience slower language\u00a0processing during a word recognition task<\/strong><\/p>\n

by Mark McGowan<\/p>\n

Toddlers fitted with cochlear implants take more time, on average, to
\nprocess spoken words in their vocabulary than their normal-hearing peers,
\naccording to a study led by a professor from NIU.<\/p>\n

Tina Grieco-Calub, who was a post-doctoral student at the University of
\nWisconsin-Madison during the time of the 2006-2008 study, said that those
\ntime delays \u2013 on the order of milliseconds \u2013 could impact how children with
\ncochlear implants learn new words.<\/p>\n

And, Grieco-Calub said, if these children are taking longer to process the
\nwords that they know, they might miss opportunities to learn new words and
\nexpand their vocabularies.<\/p>\n

Published in the December 2009 issue of the Journal of Speech, Language and
\nHearing Research, the research funded by a National Institutes of Health
\ngrant gives clinicians and parents the understanding that children with
\ncochlear implants need more time to process auditory information.<\/p>\n

Cochlear implants are intended only for children who have severe to profound
\nhearing loss or who are deaf.<\/p>\n

\u201cThere are a number of published studies involving school-age children with
\ncochlear implants that look at their language outcomes \u2013 standardized
\nmeasures of spoken language performance, expressive or receptive \u2013 but they
\ndon\u2019t tell us how these children are processing auditory information on a
\nreal-time basis,\u201d Grieco-Calub said.<\/p>\n

\u201cThis gives us insight into how children process language, particularly when
\ntheir vocabularies are starting to emerge \u2013 right in the middle of the
\nlanguage explosion,\u201d she added. \u201cEven though their language appears to be
\ndeveloping, many children do not appear to be processing information as
\nefficiently as children with normal hearing.\u201d<\/p>\n

Grieco-Calub and her co-researchers, Jenny Saffran and Ruth Litovsky, used
\nvideo cameras and special software to digitally record eye movements and
\ndetermine the length of reaction time from spoken cue to visual response.<\/p>\n

Forty-six 2-year-old children participated, 26 of whom have cochlear
\nimplants.<\/p>\n

Four objects \u2013 baby, ball, doggy and shoe \u2013 were chosen for the study. \u201cWe
\nverified with their parents that those words were in their vocabularies,\u201d
\nshe said.<\/p>\n

Children were seated in a double-walled, sound-attenuated booth. As the
\nresearchers played recordings of questions regarding the test words \u2013 \u201clook
\nat the,\u201d \u201cwhere is the\u201d and \u201ccan you find\u201d \u2013 children turned their eyes
\ntoward the corresponding objects.<\/p>\n

The toddlers were seated in infant seats or on the laps of caregivers, who
\nwere listening to music via earphones to eliminate the possibility that they
\nmight bias the children\u2019s behavior during the experiment.<\/p>\n

\u201cOn average, children with cochlear implants took longer to look at the
\ntarget objects after hearing the target label,\u201d Grieco-Calub said. \u201cSome did
\nperform similarly to their normal-hearing peers but others performed much
\npoorer.\u201d<\/p>\n

Researchers also discovered that adding acoustic competition \u2013 a background
\nnoise of two-talker babble \u2013 further slowed the reaction time of both groups
\nof children. The researchers believe this could have implications for
\nchildren who need to comprehend language when there is considerable
\nbackground noise.<\/p>\n

Consequently, Grieco-Calub said, parents and teachers should strive to
\nminimize background noise and provide visual cues.<\/p>\n

Grieco-Calub is a professor in the School of Allied Health and Communicative
\nDisorders, housed in the NIU College of Health and Human Sciences.<\/p>\n
