Design outcomes

Primary

MeasureTime frame
The main study measurement is the contrast between BOLD responses for the various task conditions. We will also measure effective connectivity in brain activity, heart rate, heart rate variability, pupil dilation, and behaviour (body sway, reaction time and accuracy) during the different conditions of the task.

Secondary

MeasureTime frame
Not applicable.

Countries

Netherlands
