P300 Trial Behaviours

Several P300 flashing methods are implemented in provided trial behaviours, all of which use a StimulusPresenterCollection and expect simple stimulus presentation to toggle on and quickly off again. Use of the standard ColourToggleStimulusPresenter is implied (but not required).

Single Flash

These trial behaviours trigger a single presenter at a time, sending single flash markers. The base SingleFlashTrialBehaviour flashes presenters in a random order.

Context-Aware Single Flash

Triggers only visible presenters in a placement-optimized sequence.

Multi-Flash

These trial behaviours trigger multiple presenters simultaneously, sending multi-flash markers.

Grid

Provides shared fields to grid based flashing patterns (row-column and checkerboard). Proper functioning of these behaviours relies on the referenced presenters being indexed in order of arrangement.

Row-Column

Triggers an entire row or column of presenters in turn.

Checkerboard

Triggers varied sets of non-adjacent presenters, collected like the alternating black and white tiles of a checkerboard.

Context-Aware Multi Flash

Triggers varied sets of non-adjacent visible presenters, collected according to position.
