Who is the better eyewitness? Sometimes Adults but at Other Times Children

Suggestibility is regarded as a major issue when children testify in court. Many legal professionals and memory researchers view children as inferior witnesses. Although differences exist between children and adults in suggestibility, these are much more complex than is usually assumed. We show that under certain conditions, adults are more susceptible to suggestion and false memories than children. We demonstrate that age-related shifts in suggestibility and false memory appear contingent on how fast and automatic children and adults make associations when experiencing events. Specifically, when confronted with suggestive information about a related, but non-experienced detail, adults more frequently than children, automatically generate links between items experienced and those already in memory making them more susceptible to suggestion than children

Undermining belief in false memories leads to less efficient problem-solving behaviour

Memories of events for which the belief in the occurrence of those events is undermined, but recollection is retained, are called nonbelieved memories (NBMs). The present experiments examined the effects of NBMs on subsequent problem-solving behaviour. In Experiment 1, we challenged participants’ beliefs in their memories and examined whether NBMs affected subsequent solution rates on insight-based problems. True and false memories were elicited using the Deese/Roediger–McDermott (DRM) paradigm. Then participants’ belief in true and false memories was challenged by telling them the item had not been presented. We found that when the challenge led to undermining belief in false memories, fewer problems were solved than when belief was not challenged. In Experiment 2, a similar procedure was used except that some participants solved the problems one week rather than immediately after the feedback. Again, our results showed that undermining belief in false memories resulted in lower problem solution rates. These findings suggest that for false memories, belief is an important agent in whether memories serve as effective primes for immediate and delayed problem-solving

The Privatization Origins of Political Corporations: Evidence from the Pinochet Regime

We show that the sale of state owned firms in dictatorships can help political corporations to emerge and persist over time. Using new data, we characterize Pinochet’s privatizations in Chile and find that some firms were sold underpriced to politically connected buyers. These newly private firms benefited financially from the Pinochet regime. Once democracy arrived, they formed connections with the new government, financed political campaigns, and were more likely to appear in the Panama Papers. These findings reveal how dictatorships can influence young democracies using privatization reforms

Skirting the Issue: What Does Believing in Repression Mean?

We show that, in contrast to Brewin, Li, Ntarantana, Unsowrth, and McNeilis (2019), large proportions of laypersons believe in the scientifically controversial phenomenon of unconscious repressed memories. We provide new survey data showing that when participants are asked specific questions about what they mean when they report that traumatic memories can be repressed, most provide answers strongly consistent with unconscious repression. Our findings continue to show that researchers, legal professionals, and clinicians should be wary of invoking unconscious repression in their work.

Misinformation increases symptom reporting: a test – retest study

OBJECTIVES: We examined whether misleading information (i.e. misinformation) may promote symptom reporting in non-clinical participants. DESIGN: A test-retest study in which we collected baseline data about participants' psychological symptoms and then misinformed them that they had rated two target symptoms relatively highly. During an interview, we determined whether participants would notice this misinformation and at direct and one-week follow-up, we evaluated whether the misinformation would exacerbate retest measures of the same symptoms. SETTING: A psychological laboratory. PARTICIPANTS: A total of 78 undergraduate students. MAIN OUTCOME MEASURES: Participants' scores on a widely used self-report measure of psychological symptoms. RESULTS: We found that most participants (63%) were blind to the discrepancies between their original symptom ratings and the upgraded scores they were misinformed with. Furthermore, at the one-week follow-up retest, blind participants revised their symptom ratings in the direction of the misinformation (i.e. they increased their ratings of these symptoms). CONCLUSION: Introspective monitoring of common psychological symptoms is poor and this creates an opportunity for misinformation and symptom escalation. Our finding bears relevance to theories about the iatrogenic amplification of medically unexplained symptoms

Acute dissociation predicts rapid habituation of skin conductance responses to aversive auditory probes

Item does not contain fulltextThe present study examined how acute dissociation, trait-like dissociative symptoms, and physiological reactivity relate to each other. Sixty-nine undergraduate students were exposed to 14 aversive auditory probes, while their skin conductance responses were measured. A combination of self-reported anxiety and trait-like dissociation was found to predict variability in peritraumatic dissociation levels induced by the aversive probes. Furthermore, high levels of acute dissociation were associated with faster habituation of skin conductance responding, while trait-like dissociation was unrelated to habituation. Interestingly, individuals who reported childhood trauma displayed elevated skin conductance responses. Our findings contribute to the growing body of evidence indicating that subjective feelings of acute dissociation have their objective concomitants, notably fast habituation of physiologic responses

Belief in Unconscious Repressed Memory Persists

Based on converging research, we concluded that the controversial topic of unconscious blockage of psychological trauma –i.e., repressed memory- remains very much alive in clinical, legal, and academic contexts (Otgaar et al., 2019). In his commentary, Brewin (in press) conducted a co-citation analysis and concluded that scholars do not adhere to the concept of unconscious repression. Furthermore, he argued that previous survey research did not specifically assess unconscious repression. Here, we present critical evidence that runs counter to his claims. First, we inspected his co-citation analysis and found that some scholars ascribe to notions closely related to unconscious repression. Furthermore, we conducted another analysis based on papers’ similarity between each other. Again, we found examples of scholars specifically endorsing unconscious repressed memories. Second, contra Brewin, recent survey research now exists that bears directly on people’s beliefs regarding unconscious repression. This work reveals that large percentages of people (students and EMDR clinicians) endorse the concept of unconscious repressed memories. The belief in unconscious repressed memory can continue to contribute to harmful consequences in clinical, legal, and academic domains (e.g., false accusations of abuse)

Eye movement desensitization and reprocessing (EMDR) Practitioners’ Beliefs about Memory

Eye movement desensitization and reprocessing (EMDR) is a widely used treatment for posttraumatic stress disorder. The idea behind EMDR is that lateral eye movements may mitigate the emotional impact of traumatic memories. Given the focus on changing patients' memories, it is important that EMDR practitioners have detailed knowledge about human memory. We explored beliefs and ideas about memory in samples of EMDR practitioners (Study 1: n = 12; Study 2: n = 41), students (Study 1: n = 35; Study 2: n = 24), and researchers (Study 2: n = 30). All groups seemed to be aware of the fallibility of memory. However, a majority of the surveyed EMDR practitioners (70-90%), students (around 90%), and researchers (66.7%) endorsed the controversial idea of repressed memories. Skepticism and endorsement of problematic ideas about memory-related topics may coexist within the same group. In clinical settings, this might be problematic, because a strong belief in repressed memories might lead therapists to suggestively seek for such memories in patients
