Active Visual Field - TAP-M

With this task the size of the active visual field is measured. The paradigm used requires the detection of colour changes of blue circles that fill the screen. These critical events appear in different spatial locations and eccentricities from the centre of the screen. To ensure fixation and to prevent eye movements to the periphery, a selective visual attention task is presented centrally with the subject having to respond to certain critical stimuli (10 or 01) that can be vertically or horizontally oriented.
