Description of Research Expertise

RESEARCH INTERESTS:
My research focuses on social communication, its development and the auditory processing mechanisms for music and speech. I apply these interests to the study of neurodevelopmental illnesses and in particular schizophrenia and autism.

KEYWORDS:
social communication, social neuroscience, emotion, auditory processing, music, speech, facial processing, EEG, fMRI, MEG, schizophrenia

RESEARCH DETAILS:
Core Research:
Most of my work to date has focused on vocal social and emotional intent as conveyed through intonation change (prosody). I have examined vocal affect signal transmission in terms of how such signals are coded, the channels used for such coding, and the receiver’s ability to process such signals. This information theoretic approach heavily relies on gestalt principles, perception and the interaction between sensory and higher-order cognitive processes.

My research approach strives for both theoretical import and applied utility. Whenever possible I employ converging methodologies, situating methods of psychophysics and neuropsychology alongside descriptions of behavior related brain activity and brain structure using (EEG) or spatially sensitive (MRI).

Building on this foundation, I have recently begun to focus on how the behavioral and neural processes involved in prosodic perception develop as we mature. I am now conducting a multimodal investigation (MEG, fMRI and DWI) of prosodic processing and in concert, developing measures tailored for studying children and adolescents.

Additional projects:
TIME PERCEPTION: I am additionally conducting investigations of the impact of time perception on higher-order cognitive abilities such as the perception of physical causality and social agency in the visual domain and phonemic perception and language and communication abilities in the auditory domain. This study will contrast the performance of healthy individuals and those with schizophrenia.

OSCILLATORY ACTIVITY DURING INTERACTIVE COMMUNICATION: I am currently beginning to develop paradigms and tools to explore inter-brain synchrony during dyadic communication interactions by measuring turn-taking and joint attention.
