Sequence representation for compatible test block. A. The schema shows a face and a word sequence presentation and the participant's response. Face and word trials are alternately presented for a short time, strictly. Positive and negative faces, along with words of positive and negative valence, are present in the stimuli set and are presented in a randomized sequence. The participant is required to classify each stimulus to the left or to the right according to labels displayed on top of the screen. When a classification response error is made, negative feedback is given (i.e., in the word sequence illustrated in the figure). B. During the incompatible block test the valence classification of a face (e.g., happy-left vs. angry-right) must be classified in the opposite valence direction of the word (unpleasant-left vs. pleasant-right). When items from compatible categories (e.g. happy + pleasant) share a response key, performance is faster and more accurate than when items from incongruent categories (e.g. angry + pleasant) share a key
