Mean, standard deviation (SD), median, interquartile range (IQR), range, and skewness are reported for the primary outcomes of the 11 EMOTICOM tasks. Shapiro–Wilks tests were used to assess normality of data; non-normal distribution of data is denoted with asterisks next to skewness (∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001). Note, mean and SD should be used as reference for normally distributed outcomes while median and IQR should be used as reference for non-normally distributed outcomes. Floor and ceiling effects are presented as percentage of test subjects who achieved the minimum score (floor effect) or maximum score (ceiling effect). aN = 68, as 32 participants performed below chance level, violating the assumptions of the reinforcement learning algorithm used to determine the alpha value.
