TABLE 1.

Operationalization of in-game tasks.

Experimental paradigm	In-game operationalization	In-game mechanic	Game output / proximal measure	Training outcome
Emotion regulation	Biofeedback	Width of the field of view linked to breathing pace	Breathing control and HRV scores	Physiological control
Response inhibition (Go/NoGo)	Shoot/don’t shoot	Shooting at targets matching dispatch information	Accuracy	Response control
Priming	Dispatch bias task	Targets’ (mis)match with dispatch information (body shape; eye color)	Accuracy based on body type of the target	Bias resistance

Model for the incorporation of experimental paradigms in the game environment; HRV, heart-rate variability.
