Institute Scientists
The Institute for Learning and Brain Sciences houses a
multidisciplinary, international team of scientists. In addition,
faculty from many University of Washington departments, and from
institutions around the world, collaborate on specific research projects
in conjunction with Institute scientists. Below are brief biographical
sketches of the Institute's Co-Directors, faculty, and
postdoctoral fellows.
CO-DIRECTORS
FACULTY & VISITING SCIENTISTS
POSTDOCTORAL FELLOWS I-LABS DIRECTORY
Co-Directors
Patricia K.
Kuhl, Ph.D.
Dr. Kuhl is a faculty member in the Department of Speech and
Hearing Sciences at the University of Washington. She is one of the
world's leading authorities on language development and a member of the
American Academy of Arts and Sciences. Her research on language played a
pivotal role in demonstrating how early experience alters brain
mechanisms. Her brain imaging research on adults is reshaping
scientists' views of critical periods in learning. The work has broad
implications for psychology, biology, linguistics, education,
neuroscience, engineering and artificial intelligence.
Andrew N.
Meltzoff, Ph.D.
Dr. Meltzoff holds the Job and Gertrud Tamaki Endowed Chair and is a member
of the Department of Psychology at the University of Washington. He also
serves as the Head of Developmental Psychology Program. A graduate of
Harvard University, with a doctorate from Oxford University, he is an
internationally renowned expert on cognitive and social development in
infants and children. His discoveries about infant imitation
revolutionized our understanding of early memory and brain development.
His research on the effects that television viewing has on infants
helped shape policy and practice. Dr. Meltzoff's 20 years of research on
young children has had a far-reaching impact on cognitive- and
neuroscience, artificial intelligence, early education, and public
policy on child care.
Faculty & Visiting Scientists
Cristina Atance, Ph.D.
Dr. Atance is a developmental psychologist at the University of Ottawa, and is working with Dr. Meltzoff. Her primary area of
interest is the development of future thinking in preschool-aged children. Scientists have discovered a lot about childrens memory
for the past, but almost nothing is known about childrens understanding of the future. Dr. Atance is currently running a series of
studies that explores childrens ability to think about and anticipate future states of the self, as well as the types of situations
that may cause these states to arise. Of particular interest is the point in development when children are able to think about a
future state that differs from their current one (e.g., anticipating being cold although one is currently hot). Childrens ability
to contemplate such temporal aspects of their selves has implications for cognitive development theories, as well as for how parents
and teachers can best talk with preschoolers about planning for the future (such as a trip to the park or what will happen after the
child is picked up from preschool)
Dr. Atance is also interested in the development of theory of mind skills, and more specifically how such skills may be related to other aspects of young childrens cognitive development.
Daniel Bernstein, Ph.D.
Dr. Bernstein received his Ph.D. in cognitive psychology from Simon Fraser University in Canada. He is currently an
Affiliate Assistant Professor, combining cognitive and perceptual science with developmental science in a line of
collaborative studies with Geoffrey Loftus (Cognitive science), Andrew Meltzoff and Cristina Atance (Developmental science).
One set of studies investigates the relationship between theory of mind and hindsight bias when privileged knowing
biases one's understanding of one's own or another's naive knowledge. Another line of studies investigates the development
of perceptual interference when exposure to degraded forms of a stimulus interfere with one's ability to identify
the stimulus. In these studies, 3- to 5-year-old children and college students complete the identical task, thus permitting
a direct comparison of performance between preschool children and adults.
Jean Decety, Ph.D.
Dr. Jean Decety was a Visiting Professor at the University of Washington Institute for Learning and Brain Sciences (2001-2005), where he headed the Social Cognitive Neuroscience Lab. In the 2005-2006 academic year he joined the faculty at the University of Chicago. Before coming to the Institute, he was a senior
scientist and head of the research program on the Neurophysiology of
Intentionality at INSERM, the French National Institute of Health and
Medical Research. He is an internationally recognized expert in
cognitive neuroscience, functional brain imaging (positron emission
tomography (PET), and functional magnetic resonance imaging (fMRI)). His
recent research focuses on the neural correlates of intersubjectivity,
empathy, and theory of mind.
Katherine Demuth, Ph.D.
Dr. Demuth received her Ph.D. in Linguistics from Indiana University, and was a postdoctoral fellow in Psychology at the University of California, Berkeley. She is currently Professor of Cognitive & Linguistic Sciences at Brown University, where she directs the Child Language Lab. She is especially interested in the contributions of both biological and environmental factors to the process of language learning. Much of her work has examined preschoolers' language development across languages and cultures, providing a unique window into normative processes of language learning. Her sabbatical at I-LABS will be spent learning more about neuro-imaging techniques that can be used with children.

Waka Fujisaki, Ph.D.
Dr. Fujisaki received her Ph. D. in psychology from Ochanomizu University in Japan. She is currently a Research Fellow of the Japan Society for the Promotion of Science and a Visiting Scientist at both the Institute for Learning and Brain Sciences, and NTT Communication Science Laboratories. Before coming to the Institute, she worked as a postdoctoral researcher at NTT Communication Science Laboratories with Shin'ya Nishida, Makio Kashino & Shinsuke Shimojo. Her research interests center around the long-term and short-term plasticity of auditory and cross-modal (auditory, visual, and tactile) systems. Her current research with Dr. Patricia Kuhl examines the link between speech perception and speech production on the second language acquisition.

Colleen Huebner, Ph.D., M.P.H.
In addition to being a member of the Institute, Dr. Huebner is an
Associate Professor in the UW School of Public Health and Community
Medicine, where she serves as Director of the Maternal and Child Health
Leadership Training program. In recognition of her library-based
programs for parents and young children, she has been nominated by
President Bush to the National Commission on Libraries and Information
Science. Dr. Huebner has published research on Dialogic Reading, an
intervention program for promoting language and emergent literacy skills
in 2- and 3-year-olds. Her current research compares the efficacy of
three different instructional methods for delivering Dialogic Reading
instruction to parents of young children in a mixed-income, rural
community sample.

Toshiaki
Imada, Ph.D.
Dr. Imada is a Research Professor in the UW Department of Speech &
Hearing Sciences and head of the Language Neuroimaging Lab at the
Institute for Learning and Brain Sciences. For the past 26 years, he has
conducted research on human information-processing mechanisms from a
psychological and engineering point of view and on artificial
intelligence from a human-science point of view for Nippon Telegraph and
Telephone Corporation (NTT) in Tokyo. In Japan, he was one of the first
researchers to study human auditory and visual information-processing in
the brain using magnetoencephalography (MEG), a cutting-edge
neuroimaging technique. The focus of his research is the use of
completely non-invasive neuroimaging methods, such as MEG and fMRI, to investigate infant acquisition of higher-order brain
functions, such as cognition and language, in their very early stages.
Christine M. Moon, Ph.D.
Dr. Moon is an Affiliate Associate Professor in the Department of Speech and Hearing Sciences in addition to her appointment as Professor of Psychology at
Pacific Lutheran University in Tacoma. Her primary research interest is the effect of very early experience on the perception of speech sounds and voice recognition,
and her laboratory is in the mother/baby care unit at Madigan Army Medical Center in Tacoma. Dr. Moon is co-founder of the International Perinatal Brain and Behavior Network.
Betty Repacholi, Ph.D.
Dr. Repacholi is a developmental psychologist and an Associate Professor
in UW Department of Psychology whose laboratory is housed at the
Institute for Learning and Brain Sciences. She received a B. Psych. and a Master's degree
in Clinical Psychology from the University of Western Australia, and a Ph. D. from the
University of California-Berkeley. She has a broad interest in children's early social-cognitive and
social-emotional development. Her most recent research centers on infants' responsiveness to,
and understanding of, other people's emotional states. She has also published research papers on
topics including theory of mind, attachment, children's gender-typed beliefs and behavior, and
the ontogeny of human disgust responses.
Maarit Silven, Ph.D.
Dr. Silven was a Visiting Scientist at the Institute for Learning and Brain Sciences in 2006. She is a Docent in Developmental and Educational Psychology at both the University of Turku and the University of Helsinki. Before coming to the Institute she worked as a Postdoctoral Researcher in the Academy of Finland at the University of Tampere. In the early 1990’s, she became among the first researchers in the world to study the developmental relationships between early parent-child interaction, language acquisition, and (pre)literacy skills from infancy to school age. She has also conducted longitudinal studies on children’s theory of mind development and attachment relationships in families. Her current research with Dr. Patricia Kuhl focuses on early speech perception and vocabulary growth in children growing up in mono- and bilingual homes.
Jessica Sommerville, Ph.D.
Dr. Sommerville is an assistant professor in the UW Department of
Psychology. She received her BSc from the University of Toronto, and
her PhD from the University of Chicago. Dr. Sommerville's research
interests center around early cognitive development, in particular, how
infants and preschoolers represent their own and other's actions. Her
current research projects include work on the development of
problem-solving abilities in infancy and infants' ability to understand
the goal-directed nature of simple action sequences. She is also
investigating preschool children's memory for their own actions and the
actions of others in the context of joint activity.
Postdoctoral Fellows
Jennifer Amsterlaw, Ph.D.
Dr. Amsterlaw
is a postdoctoral fellow working with Dr. Andrew Meltzoff. Before
coming to the Institute, she earned a Ph.D. in developmental psychology
at the University of Michigan with Henry Wellman. Dr. Amsterlaw's
research interests focus on how school-age children make sense of
complex cognitive processes like reasoning, learning, and decision-making.
Her research considers the development of children’s beliefs about
the goals, strategies, and “gold standards” that define these
everyday cognitive processes, and how these beliefs serve to organize
children’s thinking in real-life situations. In her current work,
she is examining children’s knowledge about the difference between
‘good’ and ‘bad’ thinking.
Dario Cvencek, Ph.D.
Dr. Cvencek is a postdoctoral fellow working with Dr. Andrew Meltzoff. Before coming to the Institute,
he earned a Ph.D. in cognitive psychology at the University of Washington, working with
Tony Greenwald. Dr. Cvencek’s research interests focus on the development of academic
gender stereotypes towards math and reading in elementary school children. Dr. Cvencek
investigates the role of social learning in the development of stereotypes, for example
math–gender stereotypes. He also considers how this learning of stereotypes in children
may be facilitated by a tendency of the human mind to keep one's cognitions consistent
with one another.
Barbara T. Conboy, Ph.D.
Dr. Conboy is
a postdoctoral fellow working with Dr. Patricia K. Kuhl on studies
of early language acquisition. Her research involves the use of
behavioral and event-related brain potential (ERP) methods to explore
whether very young children use their experience from one language
to facilitate learning and processing in another language. Other
research interests include the effects of input and experience on
language and brain development, and the early identification and
treatment of language impairment in bilingual children. Dr. Conboy
is also an ASHA-certified speech-language pathologist and has worked
extensively with Spanish-English bilingual as well as monolingual
children.
Adrian Garcia-Sierra, Ph.D.
Dr. Garcia-Sierra is a
Postdoctoral fellow working with Dr. Patricia K. Kuhl on studies of early language
acquisition in bilingual infants. Before coming to the Institute he earned a Ph.D.
in Speech and Hearing Sciences at the University of Texas at Austin. He is mainly
interested in understanding how knowledge of a second language affects speech perception.
In his studies, bilingual and monolingual speakers are assessed behaviorally and
electrophysiological (Event Related Potentials) while performing speech categorization
tasks in different language contexts. His studies support that bilinguals', but not
monolinguals' perception of speech sounds change depending on the language context
in which speech sound are presented. Currently he is investigating speech discrimination
in infants that are exposed to more than one language.
Henrike Moll, Ph.D.
Dr. Henrike Moll is a postdoctoral fellow working with Dr. Andrew Meltzoff. Before coming to the institute, she earned a Ph.D. in Leipzig, Germany, working with Dr. Michael Tomasello at the Max Planck Institute for Evolutionary Anthropology. She was awarded the prestigious Dilthey Fellowship by the Volkswagen Foundation to support scholars who are facing up to the complex challenges presented by a multi-cultural world. In her research, Henrike explores the development of diverse social-cognitive abilities, among them the ability to take and understand perspectives. In particular she is interested in the development of young children’s ability to understand the point-of-view of other people, and the important role that joint attention plays in this process.
Barbara Nash, Ph.D.
Barbara Nash is a postdoctoral fellow, working with Dr. Patricia K. Kuhl.
Before coming to the institute, she completed a PhD in experimental
Psychology, working with Prof. Denis Burnham at MARCS Auditory Laboratories
at the University of Western Sydney, Australia. She is mainly interested in
first and second language development and the influence of music on language
learning. Her research at iLABS is about whether young infants can learn to
discriminate foreign language sounds by playing with an interactive
television set.
Cherie Percaccio, Ph.D.
Dr. Percaccio is a postdoctoral fellow working with Dr. Kuhl on studies of language acquisition in children with autism. Together, they are investigating the phonetic discrimination abilities of at-risk infants to determine if there are early physiological markers of autism in the brain’s response to speech syllables. Since Dr. Percaccio’s graduate work with Dr. Kilgard at UTD was inspired by clinical experience, she is especially interested in the use of event-related potentials as assessment tools in humans. In graduate school, she published a series of papers investigating enrichment-induced plasticity in rat auditory cortex to model the physiological changes associated with therapy-related gains in children. At ILABS, her research program will focus on determining if clinical gains during and after therapy are associated with increased ERP discrimination and hemispheric localization of speech stimuli in children with autism.
Rajeev D. S. Raizada, Ph.D.
Dr. Raizada is a postdoctoral fellow working with Dr. Patricia K. Kuhl.
Before coming to the Institute, he earned a Ph.D. in computational
neuroscience at Boston University with Stephen Grossberg, and did
postdoctoral training in fMRI at the MGH-NMR Center with Russ Poldrack.
Dr. Raizada's research interests center around neural plasticity, with a
view to eventually exploiting plasticity to remediate learning
disabilities such as dyslexia. He is working with Dr. Kuhl on
psychophysical and fMRI studies of plasticity in speech perception.

Nairan Ramírez-Esparza, Ph.D.
Dr. Ramírez-Esparza is a postdoctoral fellow working with Dr. Patricia K. Kuhl. Before coming to the Institute she
earned a Ph.D. in Social Psychology at the University of Texas at Austin. Nairán's research interests focus on
understanding how language and cultural context influences personality and behavior. In her studies she has
found that something as subtle as the language a person is speaking can affect personality, behaviors,
feelings, and self-views. Currently, she is interested in studying how the language used by bilingual
families in their everyday lives influences speech development in infants.
Yapeng Wang, Ph.D.
Dr. Yapeng Wang is a postdoctoral fellow working with Dr. Patricia K. Kuhl. Before coming to I-LABS, he was an assistant professor in National Key Laboratory of Cognitive Neuroscience and Learning, Beijing Normal University, China. His research interests focus on the cognitive and neural mechanisms of language control and executive control in bilingual speakers. In his studies, he employed both behavioral and fMRI techniques to explore the cognitive and neural bases of language control and executive control in bilinguals. His studies showed that language control involved both "general" executive regions and task-related regions. Importantly, he found that the involvement of "general" executive regions was asymmetric depending on the direction of language switching. Currently, he is investigating the relationships between language control and executive control, and the role of social information plays in language control.
Rebecca
Williamson, Ph.D.
Dr. Williamson is a postdoctoral fellow working with Dr. Andrew Meltzoff.
Before coming to the Institute, she earned a Ph.D. in developmental psychology at Stanford University, working with Ellen Markman.
Dr. Williamson's research focuses on young children's social learning, including what children learn from others and how they do so.
Her research investigates how children learn behaviors, goals, and customs through observing others in their culture. Dr. Williamson
considers imitation to be a flexible and adaptive learning mechanism that children use differently depending on the situation —
sometimes copying what they see the expert do and sometimes employing their own cognitive solutions to solve a problem.
Her work has implications for multicultural learning, and for the education of preschoolers.
