title: Maturation effects on the synthetic sentence identification-ipsilateral competing message.
abstract: The Synthetic Sentence Identification test with ipsilateral competing message was presented to six groups of six normal-hearing subjects ranging in age from 8 through 25 years to assess whether performance improved as age increased. The scores improved for all age groups as the message-to-competition ratio decreased. Scores also improved as age increased. The interaction effect between age and message-to-competition ratio was significant (P less than 0.001). The results support previous findings and give strong evidence to support there being a maturation factor involved in auditory processing. Establishing normative data for normal-hearing children at various ages as well as data for children having central problems would now be required to make the Synthetic Sentence Identification test with ipsilateral competing message a useful test with children.
