Present neuropsychological status of subjects implanted with auditory prostheses

To assess the subject's cognitive and conceptual function, an extensive battery of neuropsychological tests were administered to each subject. Of the 13 subjects, 11 showed normal to superior cognitive and conceptual abilities; however, two of the subjects presented evidence of impaired cognitive and conceptual functioning. Subjects with right-ear implants showed asymmetry in the measures of peripheral flicker-fusion thresholds.
