There is no item vs. I wish there were an item: Implicit negation causes false recall just as well as explicit negation

When talking about absence, we may express it in a negative statement (using explicit negation e.g. I was not) or in a positive statement (using implicit negation e.g. I wished I were). Previous research has shown that explicitly negated statements may cause false recall–negated items may paradoxically be remembered as present. The current study compares false recall caused by implicit and explicit negation. Participants listened to a recording in which some objects were mentioned as present, some as absent, and some not mentioned at all. The absence of objects was expressed using explicit or implicit negation. Participants’ recall of the recording was measured either five minutes or one week after exposure to the recording. Results indicate that implicit and explicit negation lead to a nearly identical false recall of negated items. However, items not mentioned in the recording (i.e. neither mentioned nor negated) were more often recognized as present by participants exposed to implicit, rather than explicit negation. We postulate that false recall of negated items could be explained by participants remembering the item itself, but forgetting the context in which it was present (an affirmative or a negative statement), hence objects would be recalled as present just because they were spoken of.
