项目摘要
PROJECT SUMMARY/ABSTRACT
My career goal is to lead an interdisciplinary research group that investigates the influence of early
environmental variations on cognitive development and future academic success. To acquire the specific
training I will need to achieve this, I propose a project that measures socioeconomic status (SES), potential
mediators, brain function, and memory during infancy to examine the mechanisms through which both SES
disparities and bilingualism operate independently and jointly to influence developmental trajectories.
Specifically, I, and my future lab, will integrate EEG neurophysiological measures and developmental
psychology behavioral paradigms in order to investigate the effects of the linguistic environment and stress on
memory across monolingual and bilingual infants from diverse SES backgrounds.
My training to date has provided me with a strong foundation in behavioral paradigms assessing cognitive
development; my career development plan expands on these methods, providing essential new training in
EEG/ERP techniques, measurement of stress, and data collection with a low-income minority population.
Since it is my goal to lead a lab that integrates a diverse set of methodologies to address interdisciplinary
questions within the field of child development, my success as an independent researcher depends on these
skills.
Research Project
An estimated 1 in 5 American children under the age of 6 live below the poverty line. Growing up in a
lower SES home has been associated with substantially worse health and impaired psychological, cognitive,
and emotional development throughout the lifespan. Further, it is well established that socioeconomic
disadvantage in early childhood is associated with a range of negative effects on later cognitive development
and academic achievement. Although some studies have suggested that bilingualism may buffer the cognitive
risk associated with socioeconomic disadvantage, others have claimed that differences in SES may attenuate
any bilingual advantages found in cognitive skills. Very few studies have attempted to examine the
independent and joint effects of SES and bilingualism on early cognitive development, and furthermore no
study to date has examined this topic during infancy. Thus, the proposed studies will examine SES, multiple
language exposure, and hypothesized pathways through which socioeconomic disparities contribute to
individual variation in early memory development. The first study will examine SES disparities in newborn brain
function across infants from monolingual and bilingual backgrounds. The second study will measure the home
linguistic environment as a possible mediator between SES and memory. Finally, I will utilize both neural and
behavioral measures to assess the associations between SES, home linguistic environment, maternal stress,
and the development of memory over the first year of life. Disentangling the independent and interacting
effects of SES and bilingualism on cognitive development is crucial for identifying mechanisms of risk and
resilience, and possible interventions, for lower SES minority children.
