I am interested in the area of developmental neuropsychology studying normal and abnormal brain and cognitive development. After completing my post graduation in Psychology from University of Lucknow, I pursued M.Phil in Clinical Psychology from the Central Institute of Psychiatry Ranchi. I did my Ph.D as a UGC fellow at the National Institute of Mental Health and Neurosciences, (NIMHANS) Bangalore, with Prof. Shobini L. Rao.
I have developed and standardized a neuropsychological test battery for children in the age range of 5-15 years as a part of my doctoral work and have also studied the growth patterns of brain functions using the growth model approach. We have observed some interesting differences in the developmental trajectory of brain functions in Indian population as compared to studies carried out in the US. Having a specialization in neuropsychology I wish to understand normal cognitive processes by looking at abnormal minds. For instance, our work on dyslexia focuses on understanding the influence of biliteracy involving distinct orthographies on reading acquisition. We are also looking at the interaction between auditory processing and auditory attention deficits in dyslexia and their relationship with phonological awareness. We have identified the cognitive markers like error monitoring, task switching, response inhibition and delay aversion as diagnostic markers of Attention deficit hyperactivity Disorder and have also looked at the developmental patterns of these attentional processes in children with ADHD and normally developing children during 6-9 years of age.
Our studies on bilingualism and cognitive control focus on language switching in Hindi-English bilinguals and role of proficiency in bilingual language processing in cognitive control in bilinguals. We are conducting experiments to understand if bilingualism is a cognitive advantage. So far our results indicate that even among bilinguals proficiency in bilingual processing determines better cognitive control. We also find that cognitive advantage in bilingualism could be language specific mechanism and may not transfer as a general cognitive advantage.
At CBCS, I am also associated with the outreach programs organized to educate parents and school teachers about brain and cognitive development and developmental disorders like learning disabilities, dyslexia, ADHD, autism etc.
