  • Hearing a statement now and believing the opposite later
    Publication . Garcia-Marques, Teresa; Silva, Rita Rocha da; Reber, Rolf; Unkelbach, Christian
    Existing findings on the truth effect could be explained by recollection of the statements presented in the exposure phase. In order to examine a pure fluency account of this effect,we tested a unique prediction that could not be derived from recollection of a statement. In one experiment, participants judged the truth of a statement that had the same surface appearance as a statement presented earlier but contradicted it, for example “crocodiles sleep with their eyes open” one week after having heard “crocodiles sleep with their eyes closed”.We predicted and found that participants judged contradictory statements as being more false than new statements after a delay of only a fewminutes, but judged them as more likely to be true after oneweek. In contrast to earlier findings, this result cannot be explained by accounts relying on recollection of the previously presented statements.

  • The informative value of type of repetition: Perceptual and conceptual fluency influences on judgments of truth
    Publication . Silva, Rita Rocha da; Garcia-Marques, Teresa; Reber, Rolf
    We contrast the effects of conceptual and perceptual fluency resulting from repetition in the truth effect. In Experiment 1, participants judged either verbatim or paraphrased repetitions, which reduce perceptual similarity to original statements. Judgments were made either immediately after the first exposure to the statements or after one week. Illusions of truth emerged for both types of repetition, with delay reducing both effects. In Experiment 2, participants judged verbatim and paraphrased repetitions with either the same or a contradictory meaning of original statements. In immediate judgments, illusions of truth emerged for repetitions with the same meaning and illusions of falseness for contradictory repetitions. In the delayed session, the illusion of falseness disappeared for contradictory statements. Results are discussed in terms of the contributions of recollection of stimulus details and of perceptual and conceptual fluency to illusions of truth at different time intervals and judgmental context conditions.
