- The CRISP JR. Test will be used to assess speech perception in noise in both the unilateral and bilateral listening conditions for children ages 2.5-5 years. This test is designed with 12 monosyllabic and 4 bi-syllabic words that are within the receptive language and vocabulary of 2.5- to 3.0-year-old children (Garadat & Litovsky, 2007). This test was developed and is licensed from the University of Wisconsin - Madison . Speech perception will be measured using a four- alternative forced choice paradigm. Target speech and background two-talker female babble will be presented from the front (0 degrees). Speech reception thresholds are measured adaptively using a three-down/one-up algorithm finding the 79.4% correct level.
