Oscillatory Neural Correlates of Police Firearms Decision-Making in Virtual Reality.

We investigated the neural signatures of expert decision-making in the context of police training in a virtual reality-based shoot/don't shoot scenario. Police officers can use stopping force against a perpetrator, which may require using a firearm and each decision made by an officer to discharge their firearm or not has substantial implications. Therefore, it is important to understand the cognitive and underlying neurophysiological processes that lead to such a decision.

Time and memory distrust shape the dynamics of recollection and belief-in-occurrence.

The current study examined how people's metamemory judgments of recollection and belief-in-occurrence change over time. Furthermore, we examined to what extent these judgments are affected by memory distrust - the subjective appraisal of one's memory functioning - as measured by the Memory Distrust Scale (MDS) and the Squire Subjective Memory Scale (SSMQ). Participants (= 234) studied pictorial stimuli and were tested on some of these stimuli later in the same session, but were tested on other stimuli 1, 2, 4, 8, and 17 days later.

Effects of cueing multiple memories of eating on people's judgments about their diet.

Past research shows that recalling a single positive health-related experience, such as exercising, can encourage people's subsequent healthy behaviours. In contrast, we reasoned that attempting to recall healthy experiences might elicit a metacognitive experience of difficulty that would lead people to perceive themselves as less healthy, and perhaps to make other health-related judgments based on this perception. In two pre-registered experiments (combined = 729), participants recalled either "few" or "many" instances of eating either healthily or unhealthily, before rating the healthiness of their diets and completing measures of their eating preferences and choices.

Preference for cheap-and-easy memory verification strategies is strongest among people with high memory distrust.

When choosing strategies for verifying one's memory, people are more influenced by the perceived cost of using a strategy than by its likelihood of yielding reliable information (i.e., ).

False remembering in real life: James Ost's contributions to memory psychology.

This special issue honours James Ost's (1973-2019) contributions to our understanding of false and distorted remembering. In our editorial, we introduce some of James' distinctive research themes including the experiences of people who retract "recovered" memories, social (e.g.

Memories people no longer believe in can still affect them in helpful and harmful ways.

People can come to "remember" experiences they never had, and these false memories-much like memories for real experiences-can serve a variety of helpful and harmful functions. Sometimes, though, people realize one of their memories is false, and retract their belief in it. These "retracted memories" continue to have many of the same phenomenological characteristics as their believed memories.

Front-of-pack health imagery on both 'healthy' and 'unhealthy' foods leads people to misremember seeing health claims: Two memory experiments.

Front-of-pack health imagery can shape people's inferences about food products' health benefits, even leading people to falsely remember reading health claims they never saw. However, research has typically examined these effects in situations where participants have little contextual information to guide their inferences about a product. The present research aimed to replicate the finding that front-of-pack health imagery leads participants to falsely remember reading health claims.

Misremembering Brexit: partisan bias and individual predictors of false memories for fake news stories among Brexit voters.

Exposure to fake news stories can result in false memories for the events portrayed, and this effect can be enhanced if the stories conform to the reader's ideological position. We exposed 1299 UK residents to fabricated news stories about Brexit. 44% of participants reported a false memory for at least one fabricated story, with a higher rate of false memories for stories that reflected poorly on the opposing side.

Front-of-pack images can boost the perceived health benefits of dietary products.

Images on dietary supplement packaging can help identify the products' supposed function. However, research shows that these images can also lead people to infer additional health benefits of consuming the products. The present research investigated the extent to which front-of-pack imagery affects people's perceptions of the health risks and benefits of fictional products.

Weak memory for future-oriented feedback: investigating the roles of attention and improvement focus.

Recent research showed that people recall past-oriented, evaluative feedback more fully and accurately than future-oriented, directive feedback. Here we investigated whether these memory biases arise from preferential attention toward evaluative feedback during encoding. We also attempted to counter the biases via manipulations intended to focus participants on improvement.

Reasons to Doubt the Reliability of Eyewitness Memory: Commentary on Wixted, Mickes, and Fisher (2018).

Wixted, Mickes, and Fisher (this issue) take issue with the common trope that eyewitness memory is inherently unreliable. They draw on a large body of mock-crime research and a small number of field studies, which indicate that high-confidence eyewitness reports are usually accurate, at least when memory is uncontaminated and suitable interviewing procedures are used. We agree with the thrust of Wixted et al.

A memory advantage for past-oriented over future-oriented performance feedback.

People frequently receive performance feedback that describes how well they achieved in the past, and how they could improve in future. In educational contexts, future-oriented (directive) feedback is often argued to be more valuable to learners than past-oriented (evaluative) feedback; critically, prior research led us to predict that it should also be better remembered. We tested this prediction in six experiments.

False memories, nonbelieved memories, and the unresolved primacy of communication.

Mahr & Csibra (M&C) make a compelling case for a communicative function of episodic remembering, but a less compelling case that this is its primary function. Questions arise on whether confirming their predictions would support their account sufficiently, on the communicative function of preserving rich, nonbelieved memories, and on the epistemic benefits of developing false memories via the acceptance of misinformation.

Responsibility-Sharing in the Giving and Receiving of Assessment Feedback.

Many argue that effective learning requires students to take a substantial share of responsibility for their academic development, complementing the responsibilities taken by their educators. Yet this notion of responsibility-sharing receives minimal discussion in the context of assessment feedback, where responsibility for enhancing learning is often framed as lying principally with educators. Developing discussion on this issue is critical: many barriers can prevent students from engaging meaningfully with feedback, but neither educators nor students are fully empowered to remove these barriers without collaboration.

Changing beliefs about past public events with believable and unbelievable doctored photographs.

Doctored photographs can shape what people believe and remember about prominent public events, perhaps due to their apparent credibility. In three studies, subjects completed surveys about the 2012 London Olympic torch relay (Experiment 1) or the 2011 Royal Wedding of Prince William and Kate Middleton (Experiments 2-3). Some were shown a genuine photo of the event; others saw a doctored photo that depicted protesters and unrest.

Public Attitudes on the Ethics of Deceptively Planting False Memories to Motivate Healthy Behavior.

Researchers have proposed that planting false memories could have positive behavioral consequences. The idea of deceptively planting 'beneficial' false memories outside of the laboratory raises important ethical questions, but how might the general public appraise this moral dilemma? In two studies, participants from the USA and UK read about a fictional 'false-memory therapy' that led people to adopt healthy behaviors. Participants then reported their attitudes toward the acceptability of this therapy, via scale-rating (both studies) and open-text (study 2) responses.

When is an image a health claim? A false-recollection method to detect implicit inferences about products' health benefits.

Objective: Images on food and dietary supplement packaging might lead people to infer (appropriately or inappropriately) certain health benefits of those products. Research on this issue largely involves direct questions, which could (a) elicit inferences that would not be made unprompted, and (b) fail to capture inferences made implicitly. Using a novel memory-based method, in the present research, we explored whether packaging imagery elicits health inferences without prompting, and the extent to which these inferences are made implicitly.

A robust preference for cheap-and-easy strategies over reliable strategies when verifying personal memories.

People depend on various sources of information when trying to verify their autobiographical memories. Yet recent research shows that people prefer to use cheap-and-easy verification strategies, even when these strategies are not reliable. We examined the robustness of this cheap strategy bias, with scenarios designed to encourage greater emphasis on source reliability.

Sub-types of nonbelieved memories reveal differential outcomes of challenges to memories.

Nonbelieved memories (NBMs) highlight the independence between distinct metamemorial judgements that contribute to the experience of remembering. Initial definitions of NBMs portrayed them as involving the withdrawal of belief in occurrence despite sustained recollection. While people rate belief for their NBMs as weaker than recollection, the average difference is too small to support the idea that autobiographical belief is completely withdrawn in all cases.

Truthiness and falsiness of trivia claims depend on judgmental contexts.

When people rapidly judge the truth of claims presented with or without related but nonprobative photos, the photos tend to inflate the subjective truth of those claims--a "truthiness" effect (Newman et al., 2012). For example, people more often judged the claim "Macadamia nuts are in the same evolutionary family as peaches" to be true when the claim appeared with a photo of a bowl of macadamia nuts than when it appeared alone.

On the persuadability of memory: Is changing people's memories no more than changing their minds?

The observation of parallels between the memory distortion and persuasion literatures leads, quite logically, to the appealing notion that people can be 'persuaded' to change their memories. Indeed, numerous studies show that memory can be influenced and distorted by a variety of persuasive tactics, and the theoretical accounts commonly used by researchers to explain episodic and autobiographical memory distortion phenomena can generally predict and explain these persuasion effects. Yet, despite these empirical and theoretical overlaps, explicit reference to persuasion and attitude-change research in the memory distortion literature is surprisingly rare.

People consider reliability and cost when verifying their autobiographical memories.

Because memories are not always accurate, people rely on a variety of strategies to verify whether the events that they remember really did occur. Several studies have examined which strategies people tend to use, but none to date has asked why people opt for certain strategies over others. Here we examined the extent to which people's beliefs about the reliability and the cost of different strategies would determine their strategy selection.

Disowned recollections: denying true experiences undermines belief in occurrence but not judgments of remembering.

Recent research findings have illustrated that false memories induced in the laboratory can be dissociated from the beliefs that the events had in fact occurred. In this study we assessed whether this dissociability is a quality peculiar to false memory, or whether it represents a general characteristic of autobiographical memory. To this end we examined whether people can be induced to stop believing in memories for true experiences.

Priming moral self-ambivalence heightens deliberative behaviour in self-ambivalent individuals.

Background: Recent work on cognitive-behavioural models of obsessive-compulsive disorder has focused on the roles played by various aspects of self-perception. In particular, moral self-ambivalence has been found to be associated with obsessive-compulsive phenomena.

Aims: In this study we used an experimental task to investigate whether artificially priming moral self-ambivalence would increase participants' deliberation on ethical problems, an index that might be analogous to obsessive-compulsive behaviour.
