Biography

The title of me thesis is : Media-multitasking and Executive Functioning in young adults


I am supervised by: Dr Anna Law, Dr Anne-Marie Adams and Dr Fiona Simmons

Project overview:
Media-multitasking is the concurrent consumption of media through multiple streams .It is a behaviour that is most widespread amongst young adults and has been associated with biases in cognitive processes known as executive functions. The initial aim of the project was to determine the relationship between self-reported frequency of media-multitasking and executive functions. This first study has been completed and the following results were found. There were no relationships between self-report media-multitasking and individuals executive function ability. However, individuals’ trait anxiety was associated with frequency of self-reported media-multitasking, with increased frequency associated with higher levels of anxiety. The second aim of the project will examine which executive functions are the best predictors of media-multitasking performance measured in the lab. The second aim of the project is currently ongoing. Finally, the latter stage of the project aims to test (using an experimental approach) whether prolonged media-multitasking fatigues executive functions (relative to serial engagement with different media). The overall findings from this project will elucidate the cognitive processes involved in media-multitasking, furthering our theoretical understanding.

Future plans
I plan to continue my career in academia with aspirations to eventually become a university lecturer in cognitive psychology. Therefore after completing my PhD I plan to take up a post-doctoral research position.
