Summary Summary: The confidence–accuracy relationship has primarily been studied through recognition tests and correlation analysis. However, cued recall is more ecological from a forensic perspective. Moreover, there may be informative ways of analysing the than correlations. In present study, participants viewed video bank robbery were asked questions covering general knowledge itself. Confidence ratings collected, correlations, calibration discrimination measures calculated. All indicated...

We examined the memory for central and peripheral information concerning a crime acceptance of false information. also studied eyewitnesses' confidence in their memory. Participants were shown video depicting bank robbery questionnaire was used to introduce The next day participants completed recognition task which they rated responses. Performance better registered more alarms contents. cognitive system's limited attentional capacity greater elements may facilitate processing important...

Two experiments are reported that investigate the impact of misinformation on memory accuracy and metacognitive resolution.In Experiment 1, participants viewed a series photographs depicting crime scene, were exposed to contradicted details in slides, later took recognition test.For each answer, required indicate whether they willing testify (report) their answer Court rate confidence.Misinformation impaired but it had no effect resolution, regardless resolution was indexed with...

We report two experiments that investigated the regulation of memory accuracy with a new regulatory mechanism: plurality option. This mechanism is closely related to grain-size option but involves control over number alternatives contained in an answer rather than quantitative boundaries single answer. Participants were presented slideshow depicting robbery (Experiment 1) or murder 2), and their was tested five-alternative multiple-choice questions. For each question, participants asked...

The influence of post-event misinformation on memory is typically constrained by postwarnings (Blank & Launay, 2014), but little known about the effectiveness particular features post-warning, such as their specificity.Experiment 1 compared two levels postwarning specificity: A general post-warning just stated presence misinformation, whereas a specific identified test items for which had been presented earlier.The not eliminated both effect and its deleterious impact monitoring (using...

Words presented in larger font size are considered more memorable and rated with higher judgments of learning (JOLs). One explanation for this phenomenon is that people believe affects memory. However, it not clear why hold belief. alternative represents importance, fonts implying relevant information. More important information judged as is, fact, better remembered. In Experiments 1 2 we words small (18 points) extra-large (250 found JOLs importance fonts. A mediation analysis showed...

Summary Misinformation has negative effects in the accuracy of eyewitnesses' reports. We investigated whether those could be reduced when participants are allowed to decide how many answers include their answers, that is, regulate plurality option. Participants watched a slideshow and received misinformation through narrative. In recognition memory test, had select, out five alternatives, one (single) then three alternatives (plural answer) indicate which they preferred report if were...

Summary Little is known about how the content of advertisements remembered. We studied product interest, thematic congruence between advertisement and programme, typicality elements an affect memory for new ads in television, radio, printed media. Participants were exposed to a single type media with two embedded ads. After filler task, they completed true/false recognition task. In television accuracy was higher interesting three experiments, we found no effect congruence, standard...

Judgments of learning (JOLs) are usually higher for high-frequency words than low-frequency words, which has been attributed to beliefs about how word frequency affects memory. The main goal the present study was explore if identifying as a relevant cue is necessary it affect JOLs. idea that one base judgments in variable memory, must first consider variable. In Experiments 1 and 2, participants studied list high- made immediate JOLs, answered questions aimed at cues used make those results...

Research on conversational exchanges shows that people attempt to optimise their responses' relevance when they definitely know the correct answer (e.g., "What time is it?"). However, such certainty often unavailable while speakers may still be under social pressure provide an answer. We investigated how context influences informativeness level answering questions uncertainty. In three experiments, participants answered difficult general-knowledge placed in different contexts (formal vs....

Summary When co‐witnesses exchange information, false information may be presented, and memories could created. This co‐witness suggestibility effect has been studied in face‐to‐face interactions, little is known about the impact of online discussions on co‐witnesses' memories. In two experiments, we explored whether (1) appeared following discussion (2) enlightenment instructions reduced effect. We created a virtual variant MORI procedure, MORI‐v technique, which participants watched short...

Summary Production frequency has often been used to identify central and peripheral information, under the assumption that high implies item is central. However, no research date tested relationship between centrality frequency. Participants watched a video of bank robbery completed free recall test, from which for recalled items was computed. Two groups then same rated forensic relevance each item. Results showed most, but not all, with were as forensically relevant low diagnostic either or...

Memory tests are frequently used to measure the effectiveness of an advertisement. However, as different provide kinds information it is important know which type test most appropriate. The main objective this investigation was study effect memory on number brands recalled and level interest generated by them. A group participants wrote down all any kind product that they remembered having seen advertised (free recall test) rated their in each brand. Subsequently, were given a list 27...

We examined memory performance in multiple‐choice questions when correct answers were not always present. How do participants answer they are aware that the alternative may be present? To this question we allowed to decide on number of alternatives their final (the plurality option), and whether wanted report or withhold (report option). also studied benefits both options available. In two experiments watched a crime then answered with five alternatives. Half presented half not. Participants...

Beliefs about how memory works explain several effects on prospective metamemory judgments (e.g., the effect of font size learning; JOLs). Less is known beliefs retrospective (i.e., confidence). Here, we tested whether also affects confidence ratings and play a similar role in than JOLs. In two experiments, participants studied words small large size, rated JOLs, completed font-size test which they indicated at study standard old/new recognition test. The results confirmed that affected both...
