Cue removal does not affect the position of field centroids. (A) The white arrows (white card only) and black arrows (black card only) represent displacement vectors associated with card removal. As was true for pairs of standard sessions, the displacement vectors are short, indicating that card removal leaves the field centroid position alone. In addition, there is no apparent organization to the directions of the displacements. (B) Plotting the angular and radial vector field displacements against the normalized angular coordinate did not reveal any underlying pattern to displacement of field centroids. The paucity of fields in the short arc between the cards is due only to choices about which fields were recorded during removal sessions.
