Metacognition and consumer judgment: fluency is pleasant but disfluency ignites interest

Language modality influences risk perception: Innovations read well but sound even better

Psychological theories implicitly assume that the modality in which information is conveyed-spoken or written-leaves judgment and choice unaltered. Modality is rarely considered in textbooks on judgment and decision making, and the selection of modality in research is often based on convenience. We challenge this theoretical assumption. Three experiments (N = 984) show that the modality in which novel technologies are described systematically influences their perceived risk and benefit. Participants either read or heard advantages and disadvantages of novel technologies and then assessed their risk and benefit. In Study 1, spoken descriptions prompted more positive evaluations toward the technologies in terms of overall risks and benefits than written descriptions. Studies 2 and 3 replicated this modality effect and demonstrated that affect partially explains it, as spoken descriptions induced more positive feelings toward the new technologies than written descriptions. Study 3 (preregistered) showed that the influence of modality is unique to novel technologies and does not extend to familiar ones. These findings contribute theoretically to the understanding of the relationship between language and thought, and carry implications for survey research and the use of voice assistant technology.

Influence of letter shape on readers' emotional experience, reading fluency, and text comprehension and memorisation

Introduction

The amount of educational material delivered to pupils and students through digital screens is increasing. This method of delivering educational materials has become even more prevalent during the COVID-19 pandemic. To be as effective as possible, educational material must be properly designed not only in terms of content, but also in terms of form, e.g., the typeface. The present study investigated the effect of letter shape on readers' feelings of pleasantness during reading, reading fluency, and text comprehension and memorisation.

Methods

To find out whether age influences the effects of typeface shape on reading measures, we divided the participants into a group of less experienced readers (children) and more experienced readers (adults). Both groups read texts in eight different typefaces: four of them were round or in rounded shape, and four were angular or in pointed shape. With an eye-tracker, the reading speed and the number of regressive saccades were recorded as measures of reading fluency and changes in pupil size as an indicator of emotional response. After reading each text, the participants rated the pleasantness of the typeface, and their comprehension and memorisation of texts were checked by asking two questions about the text content.

Results

We found that compared to angular letters or letters in pointed shape, round letters or letters in round shape created more pleasant feelings for readers and lead to a faster reading speed. Children, as expected, read more slowly due to less reading experiences, but, interestingly, had a similar number of regressive saccades and did not comprehend or remember the text worse than university students.

Discussion

We concluded that softer typefaces of rounder shapes should be used in educational materials, as they make the reading process easier and thus support the learning process better for both younger and adult readers. The results of our study also showed that a comparison of findings of different studies may depend on the differences among the used letter shapes.

Inspiration or risk? How social media marketing of plant-based meat affects young people's purchase intention

As an alternative protein product to animal meat, plant-based meat is considered to play an essential role in improving animal welfare and protecting the environment. However, why do a few consumers choose plant-based meat but others do not? Despite the increasing research on plant-based meat marketing, little is known about the psychological mechanism by which plant-based meat marketing affects consumers' purchasing decisions. We utilize dual-system theory to understand how social media marketing of plant-based meat influences cognitive fluency, customer inspiration, perceived risk, and purchase intention. Four studies (i.e., Studies 1, 2, 3, and 4) show that social media marketing can increase young people's purchase intention of plant-based meat more than traditional marketing. In Studies 1 and 2, increased intensity of social media marketing can enhance young people's cognitive fluency and further promote purchase intention. Study 3 explores how cognitive fluency relates to purchase intention through two psychological mechanisms. We suggest that a higher level of cognitive fluency increases customer inspiration and improves purchase intention. However, a lower level of cognitive fluency reduces purchase intention by increasing perceived risk. Study 4 manipulated members' in-group or out-group status to show a boundary condition for the effect of brand community identity on purchase intention. These studies provide insight into how brand marketers can use social media to promote consumer inspiration and advertising engagement, how managers can offer fluency-increasing mechanisms to ensure a low level of perceived risk, and how enterprise practitioners may want to consider brand community publicity to attract out-group members.

Are Positive Interventions Always Beneficial?

Can people improve their lives by smiling more, trying to have a better posture, and by thinking about good memories? Can individuals become more successful by deliberatively engaging in positive actions and thoughts? Do people feel better by following recommendations from naïve psychology? In the present article we discuss these questions, noting that although some popular interventions thought to be universally beneficial (e.g., inductions of happiness, self-affirmation, empowerment, self-distancing) can sometimes yield positive outcomes, at other times the outcomes can also be negative. Taking an empirical approach based on experimental evidence, we postulate that understanding the underlying processes discovered in the science of persuasion is the key for specifying why, when, and for whom these practical initiatives are more likely to work or to backfire.

The Easier the Better: How Processing Fluency Influences Self-Efficacy and Behavioral Intention in Pro-Social Campaign Advertising

This study examines how processing fluency influences people’s behavioral intention to perform a pro-social behavior. In particular, we predict that high processing fluency enhances self-efficacy perception which, in turn, increases behavioral intention to participate in a pro-social campaign. Study 1 tested the proposed effect in the context of a pro-environmental campaign. Results showed that individual’s subjective feeling of processing fluency affects the degree of self-efficacy and intention to engage in recycling behavior. Study 2 replicated study 1 in the context of organ donation. In addition, we manipulated the degree of conceptual fluency by differently pairing message framing (gain vs. loss) and background color (blue vs. red). As predicted, participants exposed to campaign advertising with conceptually matching framing-color pairs (blue—gain framing and red—loss framing) expressed a greater level of self-efficacy than those who were exposed to mismatched pairs. In addition, self-efficacy mediated the influence of the color–framing match on the intention to donate organs. Our research contributes to the existing literature by identifying critical drivers that promote actions toward pro-social campaigns. It also provides useful guidelines for marketers who design and implement pro-social campaign communications.

Aesthetic Pleasure versus Aesthetic Interest: The Two Routes to Aesthetic Liking

Although existing research has established that aesthetic pleasure and aesthetic interest are two distinct positive aesthetic responses, empirical research on aesthetic preferences usually considers only aesthetic liking to capture participants’ aesthetic response. This causes some fundamental contradictions in the literature; some studies find a positive relationship between easy-to-process stimulus characteristics and aesthetic liking, while others suggest a negative relationship. The present research addresses these empirical contradictions by investigating the dual character of aesthetic liking as manifested in both the pleasure and interest components. Based on the Pleasure-Interest Model of Aesthetic Liking (PIA Model; Graf and Landwehr, 2015), two studies investigated the formation of pleasure and interest and their relationship with aesthetic liking responses. Using abstract art as the stimuli, Study 1 employed a 3 (stimulus fluency: low, medium, high) × 2 (processing style: automatic, controlled) × 2 (aesthetic response: pleasure, interest) experimental design to examine the processing dynamics responsible for experiencing aesthetic pleasure versus aesthetic interest. We find that the effect of stimulus fluency on pleasure is mediated by a gut-level fluency experience. Stimulus fluency and interest, by contrast, are related through a process of disfluency reduction, such that disfluent stimuli that grow more fluent due to processing efforts become interesting. The second study employed product designs (bikes, chairs, and lamps) as stimuli and a 2 (fluency: low, high) × 2 (processing style: automatic, controlled) × 3 (product type: bike, chair, lamp) experimental design to examine pleasure and interest as mediators of the relationship between stimulus fluency and design attractiveness. With respect to lamps and chairs, the results suggest that the effect of stimulus fluency on attractiveness is fully mediated by aesthetic pleasure, especially in the automatic processing style. Conversely, disfluent product designs can enhance design attractiveness judgments due to interest when a controlled processing style is adopted.
