Takarangi MKT, Bridgland VME, Simister ET. A nervous wait: Instagram's sensitive-content screens cause anticipatory anxiety but do not mitigate reactions to negative content. Cogn Emot 2023:1-15.

Abstract
Online platforms like Instagram cover potentially distressing imagery with a sensitive-content screen (blurred imagery plus a content warning). Previous research suggests people typically choose to "uncover" and view screened content. In three studies, we investigated whether the presence of screens mitigates the negative emotional impact of viewing content. In Study 1, participants viewed positive and neutral images, and screens (with an option to view the negative images beneath) for a 5-minute period. In Study 2, half the participants saw a grey mask in place of the typical sensitive-content screen. In addition, each image appeared for a fixed period (5 s) and participants had no option to uncover it. Study 3 was like Study 2 except half the participants saw negative images preceded by a sensitive-content screen and half saw negative images without screens. Overall, participants reported a significant increase in state anxiety and negative affect from pre-to post task when they were exposed to sensitive-content screens, whether or not they were also exposed to the negative imagery beneath. Our data suggest sensitive-content screens cause negative responses - state anxiety and negative affect - that do not translate to an emotional benefit when people view negative content.

To sleep or not to sleep, that is the question: A systematic review and meta-analysis on the effect of post-trauma sleep on intrusive memories of analog trauma. Behav Res Ther 2023; 167:104359.

Abstract
Distressing intrusive memories of a traumatic event are one of the hallmark symptoms of posttraumatic stress disorder. Thus, it is crucial to identify early interventions that prevent the occurrence of intrusive memories. Both, sleep and sleep deprivation have been discussed as such interventions, yet previous studies yielded contradicting effects. Our systematic review aims at evaluating existing evidence by means of traditional and individual participant data (IPD) meta-analyses to overcome power issues of sleep research. Until May 16th, 2022, six databases were searched for experimental analog studies examining the effect of post-trauma sleep versus wakefulness on intrusive memories. Nine studies were included in our traditional meta-analysis (8 in the IPD meta-analysis). Our analysis provided evidence for a small effect favoring sleep over wakefulness, log-ROM = 0.25, p < .001, suggesting that sleep is associated with a lower number of intrusions but unrelated to the occurrence of any versus no intrusions. We found no evidence for an effect of sleep on intrusion distress. Heterogeneity was low and certainty of evidence for our primary analysis was moderate. Our findings suggest that post-trauma sleep has the potential to be protective by reducing intrusion frequency. More research is needed to determine the impact following real-world trauma and the potential clinical significance.

Bücken CA, Mangiulli I, Uzun S, Otgaar H. False denials increase false memories for trauma-related discussions. Memory 2022; 30:1158-1171. [PMID: 35786402 DOI: 10.1080/09658211.2022.2094964] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Indexed: 10/17/2022]
Abstract
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. After one week, all participants received misinformation about the discussion with the experimenter and the car crash. Finally, all participants were instructed to respond truthfully in a source memory task. Participants who falsely denied information during the first session were statistically significantly more prone than honest participants to omit details they denied and to report misinformation about what was discussed in the first session. Our work suggests that false denials of a traumatic experience might lead to both forgetting and increased false memory levels for earlier conversations about the event.
