Speech-Sounds Perception Test: analysis of error types in normal and diffusely brain-damaged patients.

An analysis of the types of error (Initial, Terminal, and Both) made on the Speech-Sounds Perception Test was conducted on data collected from 104 normal controls and 56 diffusely brain-damaged patients. The brain-damaged group made more Terminal and Both errors than the normal group. A logistic regression analysis showed that knowing the types of error did not produce a higher percentage of correctly classified subjects than knowing only the total score.
