Her research includes typical perception of facial and vocal cues, both in isolation and combined, as well as the influence of traumatic brain injury and hearing loss on perception of these cues. Dr. Zupan has collaborated with Dr. Neumann, Dr. Babbage and Dr. Willer to create and assess the effectiveness of treatment programs for facial affect recognition and emotional inferencing in a clinical trial study, during which the team also created an assessment tool for emotional inferencing – The Emotional Inferencing from Stories Test (EIST). She is interested in creating a new test for emotion recognition that assesses recognition of facial and vocal expressions (both verbal and nonverbal) across the lifespan.
