Executive functions and language development
Matt Hilton, Department of Developmental Psychology, University of Potsdam, Germany
A central aim of the DFG-funded research unit “Crossing the Borders” is to better understand how general cognitive functions drive development across different domains. To this end, we have designed and implemented a battery of eye-tracking tasks that measure individual differences in the following cognitive functions: inhibitory control, sustained attention, recognition memory and processing speed. These cognitive functions have all been implicated in models of Executive Function (EF), typically defined as the controlled co-ordination of cognitive and action processes in the pursuit of goals. Our research unit has been testing this eye-tracking battery on an increasingly large sample of children at the ages of 12, 24 and 36 months. We will use this data as a starting point for thinking about the measurement and development of EF during infancy and early childhood. For a large subset of children, we have also taken measures of receptive and productive language skills, prompting for a discussion of the potential relations between EF and language development.
The eye-tracking tasks are based on methods described in the following papers:
