A STANDARDIZATION STUDY OF THE TIME COMPRESSED SENTENCE TEST

by HOUSTON, LISA MICHELLE

Abstract (Summary)
This study obtained normative data for the standardization of the Time Compressed Sentence Test (TCST) (Keith 2002). The TCST is used to identify disorders of auditory timing, referred to as temporal processing disorders and contains a practice subtest, two subtests consisting of 40% time compression, and two subtests consisting of 60% time compression. The TCST was administered to normal typically developing children. This data was imperative to establishing the norms for each subtest for each age group. 117 children between the ages of 6years 0 months and 11 years and 11 months were utilized for this study. Of the 117 subjects, 58 were males and 59 were females. To determine whether there was a significant difference between 40% time compression and 60% time compression, a 1 Within X 1 Between Repeated Measures analysis of variance (ANOVA) was carried out. There was a significant compression effect. A significant age effect was also found across the five groups of children. The ANOVA was also used to test for a Compression X Age interaction. The interaction was found to be significant. A second ANOVA (1 Within X 1 Between) was used to determine if there was a significant difference between the right and left ear scores. There was a significant Ears Main Effect. There was not a significant Ears X Age interaction. In light of the significant Compression main effect and the presence of a significant Age effect, a series of pairwise comparisons were obtained using the Tukey Honestly Significant Difference test. Comparisons were fist obtained across age groups at the 40% and 60% compression levels. It was found that the oldest age group (10-11) performed significantly better than the three youngest age groups (6-8) at 40% compression and that the youngest age group (6 yr) performed significantly worse than the other four groups. All age groups performed more poorly at 60% compression than at 40% compression. In addition, since there was a significant Ear main effect and the presence of a significant Age effect, a series of pairwise comparisons were obtained utilizing the Tukey Honestly Significant Difference Test. Comparisons were obtained across age groups for the right and left ears. It was found that the oldest age group (10-11) performed significantly better than the 6 and 8 year- olds in the Right ear. These comparisons were also obtained for the left ear indicating that the youngest age group (6yr) performed more poorly than the older age groups (7-11).
