  • Are Refugees Perceived as Criminals? Reducing the Memory Misinformation Effect in the Context of Stereotypes About Refugees

    Open Access•Malwina Szpitalak, Romuald Polczyk•ARTICLE•Applied Cognitive Psychology•2026

    The memory misinformation effect in the context of stereotypes about refugees from Syria and Ukraine was explored. After watching a film clip, participants were exposed to postevent material implying that the crime was committed by Ukrainians, Syrians, or an unspecified perpetrator. This material also included misleading details about the film clip. In Experiment 1, activating a stereotype of a distant culture (Syrians) resulted in higher vulnera…

  • Interrogative Suggestibility Revisited: An Analysis of Its Mechanisms, Correlates, and Methods of Reduction

    Open Access•Romuald Polczyk, Marta Kuczek et al.•ARTICLE•Polish Psychological Bulletin•2024

    Three experiments investigated the mechanisms, correlates, and methods of immunization against interrogative suggestibility (IS). IS involves reliance in memory reports on suggestions contained in misleading questions (Yield) and the tendency to change answers under negative feedback about the quality of previous testimony (Shift). All three studies found that the milder version of the tool used in the studies (GSS) resulted in lower Yield and Sh…

  • Protecting against misinformation: Evaluating the effectiveness of three techniques to reduce memory conformity

    Open Access•Magdalena Kękuś, Regina Dziubańska et al.•ARTICLE•British Journal of Psychology•2024•References: 59

    The memory conformity effect occurs when people witness a given incident (e.g. a crime) then talk to each other about it, and the statement of one person affects the memory account of the other person with respect to this incident. The aim of this article is to improve the quality of witness testimony by verifying the effectiveness of three methods that aim to reduce memory conformity effect: (1) an extended warning against misinformation; (2) a …

  • Anxious and distrustful – How do state anxiety and memory distrust influence the misinformation effect

    Open Access•Marta Kuczek, Malwina Szpitalak et al.•ARTICLE•Polish Psychological Bulletin•2022

    The misinformation effect is influenced by many mnestic and non-mnestic factors. This article concerns the role of two of them: 1) state anxiety, defined as a situational experience of anxiety; 2) memory distrust, understood as a constant tendency to negatively evaluate one's memory. Both factors are relevant in the situation of being a witness and are believed to have a negative effect on the magnitude of the misinformation effect. In the presen…

  • Sensory processing sensitivity and its relation to susceptibility to misinformation

    Open Access•Szymon Kamil Sadowski, S Sadowski et al.•ARTICLE•Polish Psychological Bulletin•2022

    Sensory processing sensitivity is a relatively new theoretical construct. Its main components include deeper processing of stimuli as well as a stronger response to environmental impacts, both positive and negative. The effect of misinformation, which involves the inclusion of misinformation in the witness's memory reports, can be modified by varied factors, including personality characteristics. To the knowledge of the authors, no such research …

  • Observation inflation and interrogative suggestibility: Different but related memory errors

    Open Access•Magdalena Kękuś, Regina Dziubańska et al.•ARTICLE•Polish Psychological Bulletin•2020

    The observation inflation effect consists in the fact that observing an action being performed can create false memories that this action has actually been performed by the observer. The present study examined the relationship between this effect and interrogative suggestibility. A procedure based on the Gudjonsson Suggestibility Scale was used to assess two kinds of suggestibility: the tendency to yield to suggestive questions (Yield) and the te…

  • Can placebo administered in the guise of caffeine reduce the misinformation effect

    Open Access•Jakub Nastaj, Malwina Szpitalak et al.•ARTICLE•Polish Psychological Bulletin•2019

    Research suggests that placebo can reduce the misinformation effect. We aimed to examine for the first time whether placebo administered in the guise of caffeine can reduce the misinformation effect. One hundred and twenty -three healthy volunteers were randomly assigned to four groups in a 2 Placebo (Present, Not Present) × 2 Narrative (Misleading, Correct) study design. Participants from placebo groups drank 100 ml of placebo solution. They wer…

  • Generic Conspiracist Beliefs Scale – Polish adaptation of the method

    Open Access•Adam Siwiak, Malwina Szpitalak et al.•ARTICLE•Polish Psychological Bulletin•2019

    This paper presents the results of a study on the Polish version of the Generic Conspiracist Beliefs Scale (GCBS), which was designed to measure individual differences in conspiracist thinking (Brotherton, French, & Pickering; 2013). The Polish version of the scale had excellent internal consistency as measured by Cronbach alpha: .93. The Polish version also had excellent test-retest stability. To check the validity of the questionnaire, various …

  • Psychometric properties and correlates of the Polish version of the Contingent Self-Esteem Scale (CSES)

    Open Access•Malwina Szpitalak, Romuald Polczyk et al.•ARTICLE•Polish Psychological Bulletin•2018

    In general, it is ben eficial and adaptive to have high self-esteem; however, contingent self-esteem depending on approval is not so advantageous. This article presents research on a Polish version of the Contingent Self-Esteem Scale (CSES), which measures contingent self-esteem. The CSES was administered on a total of 1,199 participants; a range of other instruments were also used to establish the validity of the CSES. The CSES proved to have ac…

  • The influence of social, para‐social, and nonsocial misleading post‐event sources on memory performance

    Open Access•Malwina Szpitalak, Mateusz Polak et al.•ARTICLE•European Journal of Social…•2016•References: 43

    Misinformation encountered after witnessing an event is known to influence subsequent memory reports about this event. In most research, misleading information was introduced impersonally, for example, by means of a written description, but it is now well established that delivering it in a social interaction is effective as well. Less is known about the relative effectiveness of impersonal post‐event misinformation compared with a socially prese…

  • Promoting eyewitness testimony quality: Warning vs. reinforced self-affirmation as methods of reduction of the misinformation effect

    Open Access•Malwina Szpitalak, Romuald Polczyk•ARTICLE•Polish Psychological Bulletin•2013

    In a typical experiment on the misinformation effect, subjects first watch some event, afterwards read a description of it which in the experimental group includes some incorrect details, and answer questions relating to the original event. Typically, subjects in the misled experimental group report more false details than those from the control group. The main purpose of the presented study was to compare two methods of reducing the misinformati…

  • Warning against warnings: Alerted subjects may perform worse. Misinformation, involvement and warning as determinants of witness testimony
