Distinctive feature scoring of the California Consonant Test.
The purpose of this study was to evaluate a distinctive feature (DF) scoring technique for List 1 of the California Consonant Test (CCT) for the purpose of improving test reliability. The CCT was presented to 50 subjects with high-frequency sensorineural hearing loss (HFSNHL). The DF scoring technique resulted in a split-half correlation of .86 compared to .78 for standard percentage-correct scoring. A partial correlation of .50 was found for DF scoring with the effect of standard scoring held constant, indicating that DF scoring accounted for 25% of the variance in scores unaccounted for by standard scoring. DF scoring also led to smaller percentage differences between the two halves of the CCT (p less than .0005). An analysis of individual feature error patterns suggests that DF scoring may provide a more effective means of differentiating among listeners with HFSNHL than traditional scoring.
