rEV, relative expected value; pWIN, probability of winning. Overall participants responded slower in the losses tasks than in the gains task with significant difference in OA (p < 0.01) and marginally significant difference in YA (p = 0.068). Bolded values corresponds to statistically significant test at p < 0.05.
