(A) Psychometric functions fitted to the average response data. (B) The effects of emotional context on C50, for each observer. Points falling on the gray line represent unity, where there is no difference between emotional and neutral contexts. Points under the line indicate increased thresholds, and points over the line indicate decreased thresholds. (C) Scatter plot of the relationship between the observer’s context effect score and their informational tendency (BIS/BAS) with regard to facial emotion perception. A context effect score below zero indicates a decrease in the threshold value, and a context effect score above zero indicates an increase in the threshold value.
