Abstract
This case study reports the findings of auditory behavioral and electrophysiological measures performed on a graduate student (identified as LN) presenting verbal disfluency and learning difficulties. Results of behavioral audiological testing documented the presence of auditory processing disorders, particularly temporal processing and binaural integration. Electrophysiological test results, including middle latency, late latency and cognitive potentials, revealed that LN's central auditory system processes acoustic stimuli differently to a reference group with normal hearing.

Sumario
En este caso se reportan los hallazgos de la conducta auditiva y las mediciones electrofisiológicas realizadas a un estudiante graduado (identificado como LN) que presentaba problemas de fluidez verbal y del aprendizaje. Los resultados de las pruebas audiológicas conductuales documentaban la presencia de alteraciones en el procesamiento auditivo, particularmente procesamiento temporal y de la integración bianural. Los resultados de las pruebas electrofisiológicas, que incluyen latencia media, latencia prolongada y potenciales cognitivos, revelan que LN presenta un procesamiento de los estímulos acústicos diferente al de un grupo control con audición normal.
