An erroneous stimulus was used for the first display of "vertical distance, non-aligned" for a small subset of the subjects. they manifest themselves as an anomalous sequence of "1" responses across trial b, c and d. look closely at the original raw scores and identify the sequence of subjects (hint: they are contiguous). visualize the raw scores in a way that highlights these values and makes their anomalous nature clear. it should make it clear not only that they are outliers but should show any features that distinguish them from ordinary outliers.
