Debunking Mental Health Misperceptions in Short-Form Social Media Videos: An Experimental Test of Scientific Credibility Cues

In recent years, short-form social media videos have emerged as an important source of health-related advice. In this study, we investigate whether experts or ordinary users in such videos are more effective in debunking the common misperception that talking about suicide should be avoided. We also explore a new trend on TikTok and other platforms, in which users attempt to back up their arguments by displaying scientific articles in the background of their videos. To test the effect of source type (expert vs. ordinary user) and scientific references (present or absent), we conducted a 2 × 2 between-subject plus control group experiment (n = 956). In each condition, participants were shown a TikTok video that was approximately 30 seconds long. Our findings show that in all four treatment groups, participants reduced their misperceptions on the topic. The expert was rated as being more authoritative on the topic compared to the ordinary user. However, the expert was also rated as being less credible compared to the ordinary user. The inclusion of a scientific reference did not make a difference. Thus, both experts and ordinary users may be similarly persuasive in a short-form video environment.

A bibliometric analysis of ohmic heating on food processing in the last two decades

Novel food processing technologies have been devised to cater to the specific requirements of consumer products and tackle the challenges associated with conventional food processing technologies. Ohmic heating is a contemporary thermal-process technology with advantages for time efficiency, improved sensory and functional quality, and enhanced energy efficiency. This bibliometric investigation aimed to analyze the level of scholarly research on ohmic heating within the field of food research over the past twenty years (2003-2023). The findings indicate an upward annual growth rate of 11.09 % in the subject of food-related ohmic heating research. A total of 769 publications have been published, involving 1841 authors. Brazil is recognized as the nation with the most research contributions while Sastry, S.K., is the most productive author, and Teixeira, J.A. is the most collaborative author. Review studies examining the impact of ohmic processes on the nutritional composition of fruits, vegetables, and grains have garnered the highest number of citations. Innovative Food Science and Emerging Technologies and the Journal of Food Engineering have emerged as the most influential journals in this field. Keywords such as "ohmic heating," "electroconductive heating," and "joule heating" are commonly used in academic publications on the application of ohmic heating in the food industry. Recent trends in this field focus on aspects such as extraction procedures, pasteurization, physicochemical components, and energy usage. Ohmic heating has a bright future. Rapidly growing research shows strong interest, especially recently, because of attractive advantages such as energy efficiency and sustainability. International collaborations will expand its applications in the food industry. Challenges include high capital costs, maintenance, and unclear regulations. Future research should focus on cost-effective materials, thermal stability, food safety, and broader applications. With a clear path, the food industry can adopt ohmic heating technology as affordable and ecofriendly technology more efficiently.

From simple agents to information sources: Readers' differential processing of story characters as a function of story consistency

The study examined how readers integrate information from and about multiple information sources into a memory representation. In two experiments, college students read brief news reports containing two critical statements, each attributed to a source character. In half of the texts, the statements were consistent with each other, in the other half they were discrepant. Each story also featured a non-source character (who made no statement). The hypothesis was that discrepant statements, as compared to consistent statements, would promote distinct attention and memory only for the source characters. Experiment 1 used short interviews to assess participants' ability to recognize the source of one of the statements after reading. Experiment 2 used eye-tracking to collect data during reading and during a source-content recognition task after reading. As predicted, discrepancies only enhanced memory of, and attention to source-related segments of the texts. Discrepancies also enhanced the link between the two source characters in memory as opposed to the non-source character, as indicated by the participants' justifications (Experiment 1) and their visual inspection of the recognition items (Experiment 2). The results are interpreted within current theories of text comprehension and document literacy.

Does having a voice disorder hurt credibility?

OBJECTIVE

The purpose of the study was to determine whether listeners were less likely to believe a statement that is produced in an atypical voice, as compared to a typical voice. It was hypothesized that an atypical voice, characterized by abnormal roughness, strain, and pitch, would elicit increased skepticism. This hypothesis was based on previous evidence that there are negative stereotypes against individuals who have a voice disorder, and that increased difficulty processing an utterance can lead to disbelief.

METHODS

In Experiment 1, 36 listeners rated obscure trivia statements (such as "the elephant is the only mammal that cannot jump" and "the first public library was opened in Vienna in 1745") as definitely false, probably false, probably true, or definitely true. The statements were produced by a speaker who used their typical voice and simulated an atypical voice (of severe deviance according to the CAPE-V), as well as two additional control speakers with typical voices. Experiment 2 was a replication of Experiment 1 with a new set of 36 listeners and a new set of speakers. In addition, Experiment 2 examined whether reduced credibility was due to negative stereotypes and/or processing difficulty, through questionnaire data and correlation analyses.

RESULTS

The results were largely consistent with the hypothesis that statements produced in an atypical voice would be perceived as less credible. In both experiments, the percentage of definitely false ratings was higher for the atypical voice than for the typical voice and control voices, with a large effect size in Experiment 1 and a medium effect size in Experiment 2. Further, Experiment 2 suggested that reduced credibility was due to negative stereotypes but not processing difficulty.

CONCLUSION

The current study reveals a social consequence of having a voice disorder, i.e., decreased perceived credibility, with implications for job-related success.

Judging Truth

Deceptive claims surround us, embedded in fake news, advertisements, political propaganda, and rumors. How do people know what to believe? Truth judgments reflect inferences drawn from three types of information: base rates, feelings, and consistency with information retrieved from memory. First, people exhibit a bias to accept incoming information, because most claims in our environments are true. Second, people interpret feelings, like ease of processing, as evidence of truth. And third, people can (but do not always) consider whether assertions match facts and source information stored in memory. This three-part framework predicts specific illusions (e.g., truthiness, illusory truth), offers ways to correct stubborn misconceptions, and suggests the importance of converging cues in a post-truth world, where falsehoods travel further and faster than the truth.
