Abstract
The present study investigated which variable correlated with recognition the most of three variables (method of alteration: Introduction or Restoration, type of alteration: Addition or Deletion, and Salience). Stimuli were pictures of scenes. An item was deleted from an original photograph (deletion change) or the deleted item was restored (addition change). Participants in the Introduction condition viewed original pictures in the learning phase and recognized changed pictures (additions or deletions) in the test phase, and participants in the Restoration condition viewed changed pictures in the learning phase and recognized original pictures in the test phase. Other participants rated salience of the changed items. Analysis showed that an effect of method of alteration was observed only for Deletion and an effect of type of alteration was observed only for Introduction. That we found method of alteration held for pictures of cats, geometric figures, and scenes (present study) shows the robustness of the effects of the method of alteration. The reason of this robustness requires further investigation.
