This study aimed to provide user-centered evidence for health professionals to make optimal use of images for the effective dissemination of health information on Facebook (FB).

Using an eye-tracking experiment and a survey method, this study examined 42 participants' reading patterns as well as recall and recognition outcomes with 36 FB health information posts having various FB post features.

The findings demonstrated that FB posts with text-embedded images received more attention and resulted in the highest recall and recognition. Meanwhile, compared to text-embedded images, visual only images yielded less effective recall of information, but they caught the viewers' attention; graphics tended to attract more attention than photos. For effective communication, the text features in FB posts should align with the formats of the images.

The findings of this study provide practical implications for health information disseminators by suggesting that text-embedded images should be used for effective health communication.

This study provided evidence of users' different viewing patterns for FB health information posts and the relationship between FB post types and recall and recognition outcomes.

The purpose of this study is to contribute to the literature on information elicitation. The authors investigated the impact of social influence strategies on eyewitness recall performance. Specifically, the authors examined the effect of social influence techniques (Cialdini, 2007) on recall performance (Experiment 1) and conducted a follow-up experiment to examine the incremental effect of social proof on the report everything cognitive interview mnemonic (Experiment 2).

Participants watched a video depicting vandalism (Experiment 1: N = 174) or a verbal altercation (Experiment 2: N = 128) and were asked to recall the witnessed event. Experiment 1: Participants were assigned randomly to one of six conditions: control (open-ended prompt), engage and explain (interview ground rules), consistency (signing an agreement to work diligently), reciprocity (given water and food), authority (told of interviewer’s training) and social proof (shown transcript from an exemplar participant). Experiment 2: The authors used a 2 (social proof: present, absent) × 2 (report everything: present, absent) between-participants design.

Across both experiments, participants exposed to the social proof tactic (i.e. compared to a model exemplar) spoke longer and recalled more correct details than participants not exposed to the social proof tactic. In Experiment 2, participants interviewed with the report everything mnemonic also spoke longer, recalled more correct details, more incorrect details and provided slightly more confabulations than those not interviewed with the report everything mnemonic.

The findings have practical value for police investigators and other professionals who conduct interviews (e.g. military personnel, doctors obtaining information from patients). Interviewers can incorporate social proof in their interviewing practices to help increase the amount and accuracy of information obtained.

As eyewitnesses provide the most valuable information for criminal investigations, it is important to further develop and test techniques for collecting eyewitness testimony so that they meet the major objective of a police interview: obtaining details pertaining to criminal actions. The purpose of this paper is to test a new instruction – the re-enactment investigative instruction – formulated to collect the most fine-grained details of a criminal event as accurately as possible. It leads the interviewee to decompose all directly recollected actions into the most minimal actions so that the event can be accurately re-enacted.

In all, 40 participants individually viewed a video depicting a robbery, were randomly assigned to a re-enactment or structured interview (SI) group and then interviewed face-to-face. Each interview was comprised of two free recall phases and a questioning phase. Manipulation of the re-enactment instruction took place in the second free recall phase of the re-enactment interviews (RIs).

The RI elicited more correct information compared to the SI (d=1.14), and slightly but not significantly less incorrect information (d=0.09). Participants in the RI condition reported significantly more details pertaining to general and specific actions.

The re-enactment instruction shows the potential to increase witness recall in a way that promotes recall of both additional correct information and investigative-relevant information.

The instruction provides witnesses a retrieval strategy that facilitates overcoming both the gap between memory availability and accessibility and the gap between memory availability and output regulation, eliciting more details with no significant increase of errors.

The purpose of this study was to explore potential witnesses' memories for a day that was experienced an unremarkable. There may be instances in an investigation in which all leads have been exhausted, and investigators use a broad appeal for witnesses who may have witnessed something important. Investigators can benefit from knowing the types of information that may be recalled in such circumstances, as well as identifying specific methods that are effective in eliciting useful information.

The present study explored how the delay to recall and recall method influenced the recollection of a seemingly unremarkable day that later became important. Participants were asked to recall an experienced event that occurred either recently (a few weeks prior) or in the distant past (a year prior). Participants recalled via either a written method, in-person individual-spoken or collaborative-spoken interviews.

Results suggest an independent benefit for individual-spoken in-person recall (compared to written or collaborative-spoken recall) and recall undertaken closely after an event (compared to delayed recall). Both individual-spoken interviews as well as more recent recollection resulted in a greater number of overall details recalled. The authors further examined the types of details recalled that might be important to progressing an investigation (e.g. other witnesses and records).

The present work provides important implications for interviewing witnesses about a seemingly unremarkable event that later became important.

Product recall messages represent an essential communication tool in crisis situations. Their function is twofold: to provide information of a practical nature regarding the defective product, and the operational process of recalling it, and to defend the reputation of the affected firm. This paper attempts to analyse the structure and the function of product recall messages published in the UK national press, using as points of reference best practice guides published by professional or governmental organisations.

By integrating the evidence of various audience theories, a comparison is made of viewers’ information processing of new interactive video advertising formats (skippable video ads) with traditional, non-skippable formats. The purpose of this paper is to focus on how exposure to a brand name at different moments during online video advertisements influences viewers’ recall.

A neuroscientific pre-test supported the selection of an arousing video, and a subsequent pre-test confirmed the scenario validity. Using a broader sample, the main study applied a 3×2 experimental design of different ad designs and formats.

Distinctions should be made between formats and audiences that lead to different information processing methods. Users exposed to skippable ads (active audiences) exert a higher control over advertising and tend to process the information presented in the initial part of an ad. In turn, users viewing non-skippable ads (passive audiences) should be exposed to the high arousal stimulus before presentation of the key information that the advertiser wants them to remember.

Advertising managers and content creators can use these results to improve the design of their online videos, and to achieve greater effectiveness in terms of information recall.

Skippable online videos have become a commonly used advertising format, but research into their effects is scarce. This study offers the first comparison of viewers’ reactions towards skippable vs non-skippable formats, in terms of brand recall and economic performance. Further research might extend this underdeveloped field of study and enhance the knowledge of video format processing in social media.

Eyewitness testimony can determine the outcome of criminal investigations. The cognitive interview (CI) has been widely used to collect informative and accurate accounts. However, face-to-face interviews have been restricted during the current pandemic, raising the need for using video-conferencing. The authors tested whether virtual interviews could produce elaborate accounts from eyewitnesses and if the CI superiority effect against a structured interview (SI) could be fully replicated online.

The authors used a 2 × 2 factorial design with interview condition (CI vs SI) and environment (face-to-face vs virtual) manipulated between-subjects. A total of 88 participants were randomly assigned to one of the four conditions. Participants watched a mock robbery and were interviewed 48 h later using either the SI or the CI. Both interviews contained the same structure and interview phases but only the CI included its key cognitive mnemonics/ instructions. Both sessions were either face-to-face or online.

Participants interviewed with the CI recalled more information than participants interviewed with the SI, regardless of the interview environment. Both environments produced a comparable amount of recall. Report accuracy was high for all groups.

This can be crucial to inform police practices and research in this field by suggesting investigative interviews can be conducted virtually in situations such as the current pandemic or when time and resources do not allow for face-to-face interviewing.

To the best of the authors’ knowledge, this is the first study showing that the CI superiority effect can be replicated online and that a fully remote CI can produce elaborate accounts.

The massive amount of available information and functionality of the Internet makes selective information seeking effortless. This paper aims to understand the selective exposure to information during a health decision-making task.

This study conducted an experiment with a sample of 36 students to examine the influence of prior attitude, perceived threat level and information limit on users’ selective exposure to and recall of coronavirus disease 2019 (COVID-19) vaccination information. Participants were assigned to two conditions with or without an upper limit of the number of articles to be examined, and this study collected the number of articles read, the number of articles included in the report and recall score of the articles after one day of the experiment.

This study found that (1) participants with a negative attitude were more inclined to view attitude-consistent information and recalled attitude-consistent information more accurately, while participants with a positive attitude viewed more balanced information; (2) participants perceiving higher health threat level recalled attitude-consistent information more accurately; and (3) an upper limit on the number of articles to be viewed does not have any impact on selective exposure.

The findings of this paper pinpoint the disparity of influence of positive and negative attitudes on selective exposure to and selective recall of health information, which was not previously recognized.

Vaccination campaigns should focus on reaching people with negative attitudes who are more prone to selective exposure to encourage them to seek more balanced information.

This is the first paper to explore selective exposure to COVID-19 vaccination information. This study found that people with a negative attitude and a higher level of perceived health threat are more prone to selective exposure, which was not found in previous research.

The high prevalence of product-harm crises (PHC) represents a continuing challenge to which firms sometimes react by announcing several smaller recalls (i.e. slicing) but at other times by announcing the recall of all faulty products at once (i.e. chunking). The slicing vs chunking phenomenon has not been identified by prior literature; this study aims to explore two research questions: Why do firms sometimes slice and other times chunk PHC? Do slicing and chunking affect firm performance differently?

The authors examined recall guidelines from the US National Highway Traffic Safety Administration (NHTSA) and conducted expert interviews as well as a quantitative analysis of 378 product recalls to determine the antecedents of slicing vs chunking. The authors further performed an event study to examine the impact of slicing vs chunking PHCs on firms’ financial performance.

The authors find that slicing vs chunking is not a deliberate strategy but rather the consequence of firms’ resource availability and constraints. Furthermore, the authors show that larger firms have a lower likelihood of slicing versus chunking. By contrast, larger R&D expenditures, and greater reputation, as well as larger recall sizes, increase the likelihood of slicing versus chunking. Finally, the results reveal that, compared to chunking, slicing PHC has a strong negative impact on firms’ stock value.

The authors relied on recalls in the US automobile industry. A possible extension would be to study the same phenomenon in other industries or other geographical areas. In addition, the results need to be generalized to other types of negative news that can be either decoupled (slicing) or coupled (chunking), especially negative news for which firms have more discretion regarding the timing of their announcements than for product recalls.

As shown by prior research (Eilert et al., 2017), firms should aim to announce recalls quickly in the wake of a PHC. Importantly though, the results indicate that speed should not come at the expense of comprehensiveness in identifying all defective products, so that only one recall is needed. As suggested by our findings about PHC, investors may react negatively to the slicing of other types of negative news; thus, the results suggest how to best communicate to external stakeholders during crises in general.

To the best of the authors’ knowledge, this is the first study that examines why firms sometimes slice and at other times chunk PHC and identifies the performance implications of these two types of recalls in response to PHC.

The purpose of this paper is to analyze the US food industry supply chain based on a case study of a leading US global processed food manufacturer to determine areas for improvement in the recall process to reduce the possibility of harming consumers with unsafe products.

Current US Food and Drug Administration and US Department of Agriculture regulations were evaluated to understand the minimum requirements placed upon members of the supply chain within the US food industry. Thereafter, a situation analysis was conducted followed by a cause and effect analysis to illustrate weaknesses within typical recall procedures. Substantiation of the analysis was based on specific information provided by managers from various functional areas of the processed food manufacturer in their interviews and their perspective about the recall/traceability process and its complexities.

Improvement concepts considered were: the implementation of Radio Frequency Identification Technology (RFID); the Food Marketing Institute (FMI) Recall Portal; and standardized global regulations within the food industry. Various phases of RFID are being piloted within the US food industry, but are not yet being widely studied due to the lack of immediate implementation requirements. Specific results pertaining to the FMI Recall Portal are not available due to its recent launch. Research indicated various regulatory processes implemented in individual countries, but no global standards have been agreed upon and initiated.

The improvement ideas have implications for timely communication among supply chain partners, resulting in less contaminated product in the hands of consumers. The ability to make these improvements will require collaboration among global suppliers through global regulations and top management support.

Understanding the gaps within current regulations and emphasizing the global footprint of how the food industry truly transformed itself into a global marketplace. Future studies need to focus on the cost impact of full RFID implementation across the entire food industry, with an understanding of cost burden ownership and worldwide integration.
