Queensland Attention and Control Lab - Garner and Dux MRI Scan Dataset

This is an fMRI dataset from the Queensland Attention and Control Lab in the School of Psychology based at The University of Queensland. The aim of the research was to investigate, through pre- and post-training MRI scanning, whether the brain adapts to be able to cope with multitasking. Negotiating the information-rich sensory world often requires the concurrent management of multiple tasks. Despite this, humans are thought to be poor at multitasking due to the processing limitations of frontoparietal and subcortical (FP-SC) brain regions. Although training is known to improve multitasking performance, it is unknown how the FP-SC system functionally changes to support improved multitasking. To address this, we characterized the FP-SC changes that predict training outcomes using an individual differences approach. Participants (N=100) performed single and multiple tasks in pre- and post-training magnetic resonance imaging (fMRI) sessions interspersed by either a multitasking or an active-control training regimen.
