Abstract
What factors affect the coding of two languages in one brain? For over 100 years, researchers have suggested that age of acquisition (when) vs. proficiency (how well) in a particular language play a role in its neural representation. Recent work in my laboratory has explored the influence of these two variables in bilingual language processing using fMRI. Studies have also extended this work by looking at these two factors in monolinguals and in motor skill processing in athletes. The similarities across these domains provide compelling evidence of the link between language and motor skill learning. They are also consistent with an emergentist view in which neural representations arise from a series of interactions at multiple levels. The implications of this conceptualization of language for clinicians and educators alike will be discussed.

Arturo Hernandez, Ph.D., is currently Associate Professor in the Department of Psychology and Director of the Developmental Cognitive Neuroscience graduate program at the University of Houston. He received his Ph.D. in Cognitive Science and Psychology from the University of California, San Diego in 1996 working with Elizabeth Bates. He spent the following year in a post-doc with Marta Kutas, also at UCSD acquiring additional expertise in Neuroimaging methods. His major research interest is in the neural underpinnings of bilingual language processing and second language acquisition. He has used a variety of neuroimaging methods as well as behavioral techniques to investigate these phenomena which have been published in a number of peer reviewed journal articles. His research is currently funded by a grant from the National Institutes of Child Health and Human Development. He has also received awards from the National Science Foundation to spend a year at the Max Planck Institute for Mind and Brain in Leipzig, Germany. More recently, he was awarded a 9 month fellowship from the Alexander von Humboldt Foundation. During this time, he investigated language processing in early child bilinguals using Near Infrared Spectroscopy and Event-related Potentials in collaboration with Professor Isabell Wartenburger and Arno Villringer at the Charite Medical University in Berlin, Germany. Hernandez interest in language learning has also been informed by having learned four languages at various points during his life. He learned Spanish and English simultaneously as a child, spending the school year at home in California and each summer in Mexico. At the age of 20, he spent two years in Brazil during which he became fluent in Portuguese. His more recent visits to Germany have the added benefit of lending personal insight into language learning well beyond the college years.
