Research Interests

Since receiving my doctorate degree in Experimental Psychology at the University of Miami (Coral Gables, Florida), I have been conducting research addressing a variety of issues related to child development, cognition, and language acquisition. My early research included topics such as animal learning models (undergraduate years), physiological psychology with emphasis on neuroscience (graduate years) and child development (post graduate years). My early research in child development focused primarily on addressing a variety of issues related to language acquisition and the assessment of language disorders in very young children. During this period I worked on research projects that investigated infant speech perception and production, designed and tested tactile communication devices for the deaf, and explored methodological strategies for objectively measuring language acquisition in preschool age children by documenting changes in linguistic skills (e.g., syntax development) based on natural observation techniques. These research efforts marked the beginnings of my interest in applied developmental psycholinguistics. More recently, I have helped developed a program of research on sensory processing and cognitive development in children and adolescents utilizing electroencephalography (EEG) and event-related potentials (ERPs) methodologies. While my current research activities focus primarily on brain activity elicited by sensory stimuli or cognitive processing tasks, I still continue to publish in the areas of general development and child language acquisition.

In our EEG/ERP research, we are examining the inter-relationship among changes in brain activity measures using a variety of task paradigms and cognitive abilities measured with neuropsychological assessments. We are obtaining these measures in children and adolescents during the developmental period of 7 years to 18 years of age. Given that this age span is believed to represent the period of maximal functional development of the prefrontal cortex, our projects are designed to test the general hypothesis that changes in the functioning of the prefrontal cortex are critical for the development of higher order cognitive abilities, specifically executive functions. Over a 4 year period, we collected ERP and behavioral data from over 400 children and 235 adults for this line of research alone. A unique aspect of this work is our demonstration of the usefulness of multivariate statistical techniques as a means of understanding individual differences within this population. We have also conducted projects that focused on measuring the test-retest reliability of cognitive ERPs in children and adults.

In a second line of EEG/ERP research, we are examining sensory registration (perception) and sensory gating (filtering) in young children, 5 to 10 years of age, with and without sensory processing disorders. The purpose of our present effort is to better understand the experimental conditions that produce the most reliable electrophysiological measures of sensory registration and sensory gating of auditory stimuli in adults and children. With our refined Sensory Gating (P50) ERP paradigm we have shown that children with sensory processing disorders display deficiencies in their ability to gate repetitive sensory (auditory) information and are exploring the interrelationships of the brain activity measures (i.e. ERPs) with behavioral manifestations of sensory processing deficits. While our current work has an emphasis on basic psychophysiological studies, our research program has the long term goal of conducting treatment effectiveness studies in clinical populations (e.g., children with autism, ADHA, sensory processing dysfunction, etc.).
