Improving processing fluency to encourage family health information seeking: The mediating role of communication efficacy.

Drawing from the metacognitive literature, this experimental study examines how the relative ease of retrieving information (i.e. processing fluency) impacts individuals' efficacy about engaging in family health discussions and interpersonal information seeking intention across two health topics: family organ donation status and family health history. Participants (N = 609) were randomly assigned to one of three conditions. Those in the easy retrieval task condition (versus a difficult or no task control), who were asked to recall information regarding two (versus six or zero) family members, reported greater processing fluency. Moreover, those who reported greater fluency also reported higher communication efficacy, and a greater intention to seek out family health information. Practically, this study highlights how metacognitive strategies may be used in healthcare settings to motivate patient information seeking. For example, it may be advantageous to start by collecting information for relatively few diseases/family members and slowly build a family history over time.

Processing Fluency and Predictive Processing: How the Predictive Mind Becomes Aware of its Cognitive Limitations

AbstractPredictive processing is an influential theoretical framework for understanding human and animal cognition. In the context of predictive processing, learning is often reduced to optimizing the parameters of a generative model with a predefined structure. This is known as Bayesian parameter learning. However, to provide a comprehensive account of learning, one must also explain how the brain learns the structure of its generative model. This second kind of learning is known as structure learning. Structure learning would involve true structural changes in generative models. The purpose of the current paper is to describe the processes involved upstream of these structural changes. To do this, we first highlight the remarkable compatibility between predictive processing and the processing fluency theory. More precisely, we argue that predictive processing is able to account for all the main theoretical constructs associated with the notion of processing fluency (i.e., the fluency heuristic, naïve theory, the discrepancy‐attribution hypothesis, absolute fluency, expected fluency, and relative fluency). We then use this predictive processing account of processing fluency to show how the brain could infer whether it needs a structural change for learning the causal regularities at play in the environment. Finally, we speculate on how this inference might indirectly trigger structural changes when necessary.

Humanizing cancer: The role of anthropomorphism and perceived efficacy in melanoma prevention

This study investigates how melanoma anthropomorphism (i.e., the attribution of humanlike qualities to melanoma) interacts with individual differences in perceived efficacy to influence attitudes and intentions to perform preventive health behaviors. Results suggested that among individuals with lower levels of perceived efficacy, presenting melanoma in anthropomorphic terms (vs. non-anthropomorphic terms) enhanced processing fluency, consequently fostering more favorable attitudes and greater intentions to follow preventive health recommendations. However, this effect was not observed among individuals with higher perceived efficacy. Findings of this study offer important theoretical and practical implications regarding the strategic use of anthropomorphism in health promotion contexts.

If it is hard to understand, is it hard to be hooked? A meta-analysis of processing fluency and transportation

This study examines the connection between processing fluency – how easily information is processed and understood, and transportation – how deeply someone becomes immersed in a narrative, unconsciously accepting its depicted reality. Additionally, it explores the potential moderating influences of medium and persuasion knowledge. By conducting a comprehensive meta-analysis that combines and analyzes data from 33 effect sizes, the study reveals a positive association between processing fluency and transportation. The findings shed light on the varying effects of transportation across different mediums, suggesting that only text and text with image, not video, through which information is presented can influence the level of transportation experienced by individuals. On the other hand, the results indicate that persuasion knowledge does not play an active role in the psychological process underlying the relationship between processing fluency and transportation. The study also discusses the theoretical and managerial implications with future research recommendations.

Research on the Matching Effect of Social Media Advertising Appeal and Narrative Person: Evidence from China

The burgeoning landscape of social media advertising also faces a myriad of challenges. This study aims to explore the interactive effect of advertising appeal (abstract vs. concrete) and narrative person (first-person vs. third-person) on consumer attitudes towards social media advertising. Based on the construal level theory, this study uses secondary data and two experiments to investigate the interactive effect between advertising appeal and narrative person in social media advertising and the moderated mediating role of information processing fluency. The result reveals that a harmonious match between advertising appeal and narrative person enhances consumer fluency in processing advertising information, thereby improving consumer attitudes towards advertising. Specifically, for advertisements with concrete appeal, first-person narratives are more conducive to enhancing consumer attitudes towards advertising. Conversely, for advertisements with abstract appeal, third-person narratives are more advantageous. This study provides theoretical insights into social media advertising narration, with practical implications for marketers to advance social media advertising design.

Illusory truth effect across languages and scripts.

The repetition of a statement increases its credibility, a phenomenon known as the illusory truth effect. Here we tested whether the illusory truth effect persists across languages and scripts. In two experiments, Italian-English (n = 80) and Greek-English (n = 66), unbalanced bilinguals were exposed to 60 written unknown trivia statements in English. After a distractor math task, participants rated the truthfulness of the same 60 (repeated) statements and 60 new statements, which were presented either in the same language as in the exposure phase (English) or in a different language (Italian, Experiment 1, or Greek, Experiment 2). Response times were faster when information was repeated in the same language compared to a different language, suggesting increased processing fluency in the former than in the latter case. Truth ratings yielded an illusory truth effect: repeated statements were considered more truthful than new statements. Interestingly, the magnitude of the illusory truth effect remained regardless of whether the repetition was in the same or in a different language and persisted even when the different language condition also entailed a different script (Latin in exposure phase and Greek in repetition). The results suggest that the language of information presentation is not a critical factor to affect the illusory truth effect, despite the fact that repetition in the same language increases processing speed. We interpret our results in light of the referential theory (Unkelbach & Rom, Cognition 160: 110-126, 2017), attributing the illusory truth effect to conceptual fluency induced by the overlap of activated conceptual representations in bilingual memory.

“I’ll Change My Beliefs When I See It”: Video Fact Checks Outperform Text Fact Checks in Correcting Misperceptions Among Those Holding False or Uncertain Pre-Existing Beliefs

Widespread concerns about the pervasiveness of misinformation have propelled one antidote to the center of scholarly attention: the journalistic fact check. Yet, fact checks often do not work as intended. While most fact checks are text only, a compelling theoretical argument can be made for using a video format instead. In this pre-registered experiment conducted in Germany ( N = 1,093), we investigated whether using video versus text can improve fact checks’ ability to correct misperceptions about transgender women, cannabis consumption, migration, and climate change. Video fact checks outperformed text fact checks, with those holding false or uncertain pre-existing beliefs benefiting the most. We contribute to motivated reasoning theory the idea that visual information can override directional reasoning better than textual information, and that processing fluency is the mechanism by which this occurs. Our findings paint an optimistic picture for the ability of fact checks to debunk misinformation, especially for those holding misperceptions.

Evidence of a metacognitive illusion in stimulus-specific prospective judgments of distraction by background speech

Two experiments served to examine how people arrive at stimulus-specific prospective judgments about the distracting effects of speech on cognitive performance. The direct-access account implies that people have direct metacognitive access to the cognitive effects of sounds that determine distraction. The processing-fluency account implies that people rely on the processing-fluency heuristic to predict the distracting effects of sounds on cognitive performance. To test these accounts against each other, we manipulated the processing fluency of speech by playing speech forward or backward and by playing speech in the participants’ native or a foreign language. Forward speech and native speech disrupted serial recall to the same degree as backward speech and foreign speech, respectively. However, the more fluently experienced forward speech and native speech were incorrectly predicted to be less distracting than backward speech and foreign speech. This provides evidence of a metacognitive illusion in stimulus-specific prospective judgments of distraction by speech, supporting the processing-fluency account over the direct-access account. The difference between more and less fluently experienced speech was largely absent in the participants’ global retrospective judgments of distraction, suggesting that people gain access to comparatively valid cues when experiencing the distracting effects of speech on their serial-recall performance firsthand.

Do images help? The impact of proenvironment photographs and graphs in environmental disclosures on investor perceptions and willingness to invest

AbstractThis study investigates the effects of proenvironment photographs and graphs in environmental disclosures on potential investors' perceptions and willingness to invest, considering the moderating role of a company's environmental performance. An online experiment was conducted with experienced investors, where participants evaluated a hypothetical company with varying environmental performance outcomes (negative or positive) presented in different formats (text only, text with photographs, or text with graphs). The results indicate that proenvironment images enhance perceived environmental responsibility for companies with negative environmental performance, whereas processing fluency is improved when the image type aligns with environmental performance. Moreover, perceived environmental responsibility mediates the impact of images on the willingness to invest in negative performance contexts. In contrast, processing fluency mediates this effect for graphs in positive performance contexts. These findings offer guidance for company managers in effectively presenting environmental data and highlight the potential risks for policy‐makers regarding the misuse of images.

Effects of color-typeface congruence on product evaluation

Product packaging is important for attracting consumer attention and creating expectations regarding a product, both of which can influence product evaluation. A key issue in package design is the coordinated selection of multiple package elements. This study investigates whether and when congruence between color and typeface in a product package can improve product evaluation. To this end, we analyze color and typeface on product packages based on semiotics and marketing, propose a conceptual model for the role of color-typeface congruence, and conduct three empirical studies that test the hypotheses implied from our model. Study 1 shows that color-typeface congruence is positively related to product evaluation. In Study 2, processing fluency is identified as a link between color-typeface congruence and product evaluation. Finally, Study 3 establishes the moderating role of design sensitivity in the relationship between processing fluency and product evaluation. Our findings contribute to more effective marketing communication for marketers and retailers through packaging.

The Effects of Numerical Evidence and Message Framing in Communicating Vaccine Efficacy

To examine the effects of numerical evidence and message framing in communicating vaccine efficacy information about infectious diseases, an online experiment presented to U.S. adults different versions of a vaccination promotional message that vary by numerical vaccine efficacy evidence: (low efficacy rate: 60% vs. high efficacy rate: 95%), outcome framing (preventing disease-related infection vs. preventing disease-related severe illness), and gain vs. loss framing, using a factorial between-subjects design. While there was no significant interaction between numerical vaccine efficacy evidence and message framing, findings showed that a higher vaccine efficacy rate increased positive beliefs about vaccination and outcome framing emphasizing infection prevention increased message processing fluency. Given that infectious diseases pose higher risks for severe illness among older adults, follow-up analyses by age showed that only younger adults were sensitive to message framing where outcome framing emphasizing infection prevention increased processing fluency.

Dynamic brain networks in spontaneous gestural communication

Gestures accent and illustrate our communication. Although previous studies have uncovered the positive effects of gestures on communication, little is known about the specific cognitive functions of different types of gestures, or the instantaneous multi-brain dynamics. Here we used the fNIRS-based hyperscanning technique to track the brain activity of two communicators, examining regions such as the PFC and rTPJ, which are part of the mirroring and mentalizing systems. When participants collaboratively solved open-ended realistic problems, we characterised the dynamic multi-brain states linked with specific social behaviours. Results demonstrated that gestures are associated with enhanced team performance, and different gestures serve distinct cognitive functions: interactive gestures are accompanied by better team originality and a more efficient inter-brain network, while fluid gestures correlate with individual cognitive fluency and efficient intra-brain states. These findings reveal a close association between social behaviours and multi-brain networks, providing a new way to explore the brain-behaviour relationship.

The Impacts of Code-Mixing in a Cross-Cultural Narrative: How Processing Fluency Impacts Narrative Engagement and Attitudes Toward Out-Groups

This experiment (N = 1,241) investigates the impact of code-mixing, defined as the use of more than one language, on processing fluency, narrative engagement, and cross-cultural attitudes. Using a sample of native English speakers located in the United States, we found that narratives that include code-mixing, a common feature of intercultural communication, felt more difficult to process and, in turn, led to more negative out-group bias and less narrative engagement. These findings integrate and extend intercultural communication and narrative theory and consider the challenges and opportunities that accompany diverse representations of characters in storytelling. Rather than highlight these challenges, however, we consider theoretically based strategies to improve audiences’ reception to cross cultural content and, in doing so, hope to inform communication practices that lead to a greater regard for others.

Analysis of Textual Complexity in Danish News Articles on Climate Change

Structural linguistic features are often overlooked yet potentially important aspects of journalistic practice. Especially in news reporting on climate change, these features can play a crucial role as the proper use of language is tied to message credibility, processing fluency and knowledge retention, which can positively influence the reader to take more climate action. This article analyzes language use in Danish news articles on climate change using a sample of around 32,000 articles from four different outlet types (quality news, niche papers, tabloids, and public service broadcasters) published from 1990 to 2021. We create a machine-learning model of text complexity covering this concept’s semantic and syntactic dimensions. Our findings confirm expected differences in complexity between news outlets, highlighting tabloid articles as engaging with higher semantic complexity, while quality papers and niche papers exhibit higher syntactic complexity. We observe a significant decrease in semantic complexity and a slight increase in syntactic complexity over time, a trend towards more generic language, and an increased use of pronouns, verbs, and adverbs. Most of these changes can be attributed to the emergence of articles by public service broadcasters. Articles by public service broadcasters are characterised by high syntactic complexity, which we consider problematic due to their popularity among the general public.

Using a signal detection approach to understand the impacts of processing fluency and efficacy on accuracy in misinformation detection.

This experiment (N = 1,019) examined how a state of processing fluency, induced through either an easy or difficult task (reading a simple vs. complex message or recalling few vs. many examples) impacted participants' ability to subsequently detect misinformation. The results revealed that, as intended, easier tasks led to higher reports of processing fluency. In turn, increased processing fluency was positively associated with internal efficacy. Finally, internal efficacy was positively related to misinformation detection using a signal detection task. This work suggests that feelings of ease while processing information can promote confidence and a more discerning style of information processing. Given the proliferation of misinformation online, an understanding of how metacognitions - like processing fluency - can disrupt the tacit acceptance of information carries important democratic and normative implications.

Loop and Enjoy: A Scoping Review of the Research on the Effects of Processing Fluency on Aesthetic Reactions to Auditory Stimuli.

Processing fluency has been shown to affect how people aesthetically evaluate stimuli. While this effect is well documented for visual stimuli, the evidence accumulated for auditory stimuli has not yet been integrated. Our aim was to examine the relevant research on how processing fluency affects the aesthetic appreciation of auditory stimuli and to identify the extant knowledge gaps in this body of evidence. This scoping review of 19 studies reported across 13 articles found that, similarly to visual stimuli, fluency has a positive effect on liking of auditory stimuli. Additionally, we identified certain elements that impede the generalizability of the current research on the relationship between fluency and aesthetic reactions to auditory stimuli, such as a lack of consistency in the number of repeated exposures, the tendency to omit the affective component and the failure to account for personal variables such as musical abilities developed through musical training or the participants' personality or preferences. These results offer a starting point in developing novel and proper processing fluency manipulations of auditory stimuli and suggest several avenues for future research aiming to clarify the impact and importance of processing fluency and disfluency in this domain.

The Effects of Titles on the Aesthetic Evaluation of Japanese Poetry

The present study tested the effect of title type on the aesthetic evaluation of Japanese poetry. Ninety participants read a Japanese poem presented with either a “descriptive” title, an “elaborative” title, or no title. Participants then gave ratings according to their aesthetic experiences on the poem. The results revealed that the title type significantly influenced the readers’ aesthetic evaluations. Specifically, descriptive titles promoted more thought about the poem compared to elaborative titles. This finding can be attributed to the enhanced processing fluency afforded by descriptive titles, which allows readers to more readily understand and grasp the key characteristics of the poem, thereby facilitating thought evocation. These results extend previous findings on the influence of titles on the aesthetic appreciation of paintings and music to the domain of poetry. Furthermore, they highlight the role of processing fluency in possibly mediating the relationship between title type and aesthetic evaluation.

Rounding for Warmth, Angling for Fluency: How Shapes, Cognitive Load, and Privacy Risk Influence App Adoption

Delving into corner shapes in interface design (i.e., circular vs. angular), we experimentally delineated two routes whereby users with strong privacy risk beliefs can be persuaded into adopting a mobile payment app through a bill-split use case. By introducing cognitive load as an ability factor and perceived privacy risk as a motivation force, this study bridges literature on user interface design with social psychology to unpack how subtle design cues impact app adoption through the lens of privacy assurance. The interplay among shapes, tasks, and user traits demonstrates the contextual efficacy of circular design to evoke social presence and the benefit of angular design to enhance processing fluency, which tap into users’ affective and cognitive needs in face of privacy risks under varied cognitive demands to encourage adoption.

Cognitive Fluency in L2: The Effect of Automatic and Controlled Lexical Processing on Speech Rate

The fluency of second language (L2) speech can be influenced by L2 proficiency, but also by differences in the efficiency of cognitive operations and personal speaking styles. The nature of cognitive fluency is still, however, little understood. Therefore, we studied the cognitive fluency of Finnish advanced students of English (N = 64) to understand how the efficiency of cognitive processing influences speech rate. Cognitive fluency was operationalised as automaticity of lexical access (measured by rapid word recognition) and attention control (measured by the Stroop task). The tasks were conducted in both L1 (Finnish) and L2 (English) to examine the (dis)similarity of processing in the two languages. Speech rate in a monologue task was used as the dependent measure of speaking performance. The results showed that after controlling for the L1 speech rate and L1 cognitive fluency, the L2 attention control measures explained a small amount of additional variance in L2 speech rate. These results are discussed in relation to the cognitive fluency framework and general speaking proficiency research.
