Conclusions
Patients with hearing loss performed more poorly than controls on the filtered word and time-compressed disyllabic word tests, but more competently on memory, reasoning, and auditory processing tasks. Complementary tests, such as those assessing central auditory processes and cognitive ability tests, are important and helpful for designing habilitation/rehabilitation and therapeutic strategies intended to optimise and stimulate cognitive skills in subjects with unilateral hearing impairment.

Objective
To analyse cognitive skills in patients with <dis>severe unilateral hearing loss</dis> versus those in subjects with normal hearing.
Methods
40 adults participated: 20 patients (10 women and 10 men) with <dis>severe unilateral hearing loss</dis> and 20 healthy subjects matched to the study group. 
Cognitive abilities were measured with the Spanish version of the Woodcock Johnson Battery-Revised; central auditory processing was assessed with monaural psychoacoustic tests. 
Box plots were drawn and t tests were performed for samples with a significance of P≤.05.
Results
A comparison of performances on the filtered word testing and time-compressed disyllabic word tests between patients and controls revealed a statistically significant difference (P≤.05) with greater variability among responses by <dis>hearing impaired subjects</dis>. 
This same group also showed a better cognitive performance on the numbers reversed, visual auditory learning, analysis synthesis, concept formation, and incomplete words tests.
