The verbal overshadowing effect is the phenomenon in which describing a previously seen face impairs its recognition (Schooler and Engstler‐Schooler, 1990). The primary purpose of this research was to investigate how the similarity between a target and distractors influences verbal overshadowing. In order to manipulate test‐set similarity, we blended the faces of different people by using morphing techniques. As a result, verbal overshadowing was found when test‐set similarity was relatively high, while the effect was not evident when there was a lesser degree of similarity. The results suggest that replicating the emergence of the verbal overshadowing effect depends on test‐set similarity. The implications of these findings for research and practice are discussed.
