Simple	WALK, STOP, $\text{WALK}$, $\text{STOP}$	Direct associations
Complex	Congruent: $\text{RED}$, $\text{GREEN}$, $\text{BLUE}$	Walk Walk/Stop	Matar et al., 2013 Shine et al., 2013d*
	Incongruent:$\text{RED}$, $\text{GREEN}$, $\text{BLUE}$, $\text{RED}$, $\text{GREEN}$, $\text{BLUE}$	Stop Stop/Walk	Matar et al., 2013 Shine et al., 2013d*

^*The blocks are counterbalanced so that half of the patients associate a congruent cue to walk and incongruent to stop and vice versa for the other half.
