  • Investigating how adopting different deceptive strategies simultaneously affects memory

    Fabiana Battista, Henry Otgaar et al.ARTICLEMemory2025

    Research has shown that lying can affect memory differently depending on the type of strategy (e.g., false denials, feigning amnesia, fabrication). At present, no studies have investigated how using different strategies simultaneously while replying to questions concerning the event impacts on memory. Hence, in the present experiment, participants watched a mock crime video, then they either told the truth (i.e., truth-telling group) or lied abou…

  • Fake memories

    Open AccessAlexa Schincariol, Henry Otgaar et al.ARTICLEMemory Mind & Media2024References: 71

    Fake news can affect people in negative ways. A recent line of research has demonstrated that when people are exposed to fake news they can form false memories for the events depicted in the news stories. We conducted a meta-analysis to obtain an estimate of the average rate of false memories elicited by fake news. Thirteen articles were included in the final analysis, revealing that nearly 40% and 60% of the participants reported at least one fa…

  • Can false denials turn fact into fiction? The effect of false denials on memory for self-performed actions

    Open AccessCharlotte A Bücken, Henry Otgaar et al.ARTICLEPsychological Research2023

    We examined the mnemonic effects of falsely denying a self-performed action. Specifically, participants ( N = 30) performed, imagined, or received no instruction about 24 action statements (e.g., “cross your arms”). Next, their memory for whether they had performed, imagined, or did nothing (i.e., received no instructions) with these actions was tested. Subsequently, participants were instructed to repeatedly deny an action they had performed (fa…

  • False denials increase false memories for trauma-related discussions

    Open AccessCharlotte A Bücken, Ivan Mangiulli et al.ARTICLEMemory2022

    False denials are sometimes used to cope with traumatic experiences. We examined whether false denials can affect true and false memory production for a traumatic event and conversations surrounding the trauma. One hundred and twenty-six participants watched a trauma analogue video of a car crash before being randomly asked in a discussion with the experimenter to (1) respond honestly or (2) falsely deny that certain details happened in the video…

  • Simulating denial increases false memory rates for abuse unrelated information

    Open AccessCharlotte A Bücken, Ivan Mangiulli et al.ARTICLEBehavioral Sciences & the Law2022

    Victims of abuse might deny their traumatic experiences. We studied mnemonic effects of simulating false denial of a child sexual abuse narrative. Participants ( N = 127) read and empathized with the main character of this narrative. Next, half were instructed to falsely deny abuse‐related information while others responded honestly in an interview. One week later, participants received misinformation for the narrative and interview. In a final s…

  • Do liars really remember what they lied upon? The impact of fabrication on memory

    Fabiana Battista, Ivan Mangiulli et al.ARTICLEMemory2021

    The present experiment aimed to examine how fabrication can affect memory. In particular, we examined whether different types of fabrication can lead to different mnemonic effects. A sample of 159 participants watched a video of a robbery and subsequently answered some questions about it. Participants were divided into three conditions: one group was instructed to tell the truth (i.e., truth-telling group), while the other two groups were instruc…

  • Believing in dissociative amnesia relates to claiming it

    Open AccessIvan Mangiulli, Marko Jelicic et al.ARTICLEMemory2021

    102) claimed to have experienced dissociative amnesia. Some claims pertained to amnesia for traumatic autobiographical experiences (e.g., sexual assault), while other claims reflected memory loss for experiences that can be regarded as non-traumatic or non-stressful (e.g., dissociative amnesia for an anniversary). Importantly, many participants believed in the existence of dissociative amnesia, and those who claimed dissociative amnesia indicated…

  • The role of executive functions in the effects of lying on memory

    Open AccessFabiana Battista, Henry Otgaar et al.ARTICLEActa Psychologica2021

    Recent studies have demonstrated that lying can affect memory and that such memory effects are based on the cognitive load required in performing the lie. The present study aimed to verify whether the impact of two deceptive strategies (i.e., false denials and fabrication) depends on individuals' cognitive resources in terms of Executive Functions (i.e., EF: Shifting, Inhibition, and Updating). A sample of 147 participants watched a video of a ro…

  • Adopting a fictitious autobiography

    Open AccessPaul Riesthuis, Henry Otgaar et al.ARTICLEMemory2020

    In the present experiment, we examined whether adopting a fictitious biography would make participants believe in this autobiography. Participants were split up into two conditions: forced confabulation condition and control condition. The forced confabulation condition received a snippet with the fake biography and had to adopt it through several methods (i.e., method acting, journaling, and convincing experimenters in an interview) over an exte…
