The lab members are currently investigating these broad research areas. However, new ideas come and the lab is ready to take up new challenges. Therefore, the entire research activity of the lab is not limited to only these areas. Prospective students and collaborators are requested to look at our publications to get an overall summary of the work. Please click on the plots here to go the journal websites.
Bilingualism and Cognition
The lab studies both linguistic (parallel language activation) and also non-linguistic (executive control) mechanisms in Indian bilinguals. Many publications from the lab show that language proficiency in bilinguals modulates both language non-selective activation and also executive control in attentionally demanding tasks. Recently we have started to explore how interpersonal knowledge about cultural and linguistic status may influence choice of language production in bilinguals. We also study how simultaneous cognitive load (working memory) influences language perception and activation in bilinguals. We use behavioral methods such as eye tracking and more traditional psycholinguistic methods to study these processes.

The ultimate goal of cognition is to produce relevant actions. However, a controversial issue has been if goal driven actions are a result of one’s top down processing or they can also result from bottom-up processing. We examine how subliminally presented primes may influence both choice and execution of actions when they are voluntary. We study both simple motor responses using eye tracking as well as complex tasks such as object naming in bilinguals.

We study how language and vision interact to produce cognition. This line of work using the popular visual world eye-tracking paradigm has demonstrated that linguistic and non-linguistic processing dynamically interact during everyday processing. We have explored this using both spoken words and also other stimuli such as pictures. Results obtained show that cognition is multimodal and very much interactive in nature.

Cognition in the Deaf
Its important to examine and extend cognitive psychological facts in a wider range of humans. We are exploring visual, attentional and executive control related issues in hearing impaired adults. Many studies show that hearing impairment leads to changes in the visual system. These advantages could be at the level of visual awareness and also attentional. We use eye tracking to study these effects in both hearing and hearing impaired participants. We wish to continue this line of study further with more investigations using brain imaging methods such as the EEG.

Cognition in Illiterates
We also study how literacy influences general cognitive abilities. Learning to read and write can have an impact on non-linguistic processes such as orienting and searching. The publication from this lab have provided evidence towards this using eye tracking and other behavioral tasks. We further aim to understand the changes in neural activity associated with acquisition of literacy.
We will be undertaking longitudinal studies involving training illiterate participants and testing them on various cognitive tasks.
