Table 5. Phonological Processing Group Differences.

Three ANCOVA models were run to evaluate mean differences between subgroups of LHS participants covarying hearing ability (Pure Tone Average (PTA) measured in decibels) and lesion volume (cubic mm). The effect of PT Lesion refers to whether a participant’s lesion intersected with the short sweeps LSM result, or did not. Sum of squares is Type III.
