Meta-Analysis of the Persuasive Effects of Metaphorical vs. Literal Messages

This study uses meta-analysis to compare the persuasive effects of metaphorical and literal messages and assess various theoretical explanations for the relatively greater persuasiveness of metaphor. The meta-analysis includes studies from 2001 to 2015 that use various message formats and topics. Results indicate an overall effect size of r = 0.09, p < .001, 95% CI [0.06, 0.12], which supports the conclusion that metaphorical messages are more persuasive than literal messages. Moderator analyses indicate differences in effect sizes based on metaphor target familiarity, message topic, and message format. A meta-regression using the theoretical moderators indicates that message format was the strongest predictor of variation in effect size. This study provides implications related to the theoretical mechanism behind the greater persuasive effects of metaphor.     

Improving the Effectiveness of Fundraising Messages: The Impact of Charity Goal Attainment,Message Framing,and Evidence on Persuasion

This experimental study assessed the effectiveness of fundraising messages. Based on recent findings regarding the effects of message framing and evidence, effective fundraising messages should combine abstract, statistical information with a negative message frame and anecdotal evidence with a positive message frame. In addition, building on research into social dilemmas, it was hypothesized that information about charity goal attainment (e.g., the contributions of others) should increase donation intentions. The hypotheses were tested in a 2 (goal attainment: yes/no)×2 (framing: positive/negative)×2 (evidence: statistical/anecdotal) factorial design. Abstract information was more effective when combined with a negatively framed message, whereas anecdotal information was more effective when combined with a positive frame. In addition, donation intentions were higher for messages that addressed charity goal attainment issues.     

Mother Goose and Mother Nature: Designing Stories to Communicate Information About Climate Change

Narratives have the ability to highlight climate change information in a relatable and engaging format. The purpose of the present investigation was to test the effects of five story structure types containing climate change information on perceived message effectiveness. Furthermore, we measured whether political affiliation moderated persuasive effectiveness of climate change messages among U.S. eligible voting adults (N = 594) who identified as Republican, Democrat, and Independent. The highest rated story overall was situated in the past, was realistic, and had clear moral values, indicating that certain appealing stories can serve as effective conduits for persuasive messages across the political spectrum. There were few differences between political affiliations, namely, that Democrats and Republicans rated messages differently on effectiveness when they differed on moral themes.     

Irony and Language Expectancy Theory: Evaluations of Expectancy Violation Outcomes

Language expectancy theory (LET) provides the basis for a study of the relationship of ironic and literal messages in terms of persuasiveness and expectedness. The experimental design was a 2 (literal vs. ironic) × 2 (compliment vs. criticism) factor design. The expectation was that literal messages would be more expected and criticisms less preferred to compliments. The results indicated that the ironic messages tended to be negative, unexpected, and attributed to the situation as opposed to the sender. Compliments were associated with fewer behavioral intentions than were criticisms. The interaction also revealed that the ironic messages were a safe middle ground between literal criticisms and compliments in terms of fostering behavioral changes.

The Effects of Metaphor Use and Message Format on Cognitive Processing and Persuasive Outcomes of Condom Promotion Messages

The potential of pictorial and verbal metaphors to gain attention and enhance persuasion is considerable. Few scholars, however, have investigated the persuasive effects of metaphor in health messages. We applied a 2 × 2 factorial experiment to examine the effects of metaphor use (metaphor/literal) and message format (verbal/pictorial) on cognitive processing and persuasive outcomes of condom promotion messages. Results showed no significant differences in cognitive processing according to metaphor or format, but there were differences in attitudes and behavioral intentions according to metaphor and format, with literal and verbal messages performing best. Potential explanations for findings and implications for future research and health message design are discussed.     

Action Mechanism of Sticky Rice-Paste-Modified Site Soil: A Traditional Chinese Cementitious Material

ABSTRACT

Sticky rice paste is a viscous material commonly used in traditional Chinese construction. It has the basic properties of high viscosity and viscoelasticity, good corrosion and weather resistance, and a small coefficient of expansion. Sticky rice paste is usually added to site soils to modify their basic physical and mechanical properties. This study found that gelatinized sticky rice-paste-modified site soils have clearly improved physical and mechanical properties compared to 20 and 100°C water-modified soils when 1% (wt%) sticky rice paste is added as the soil modifier. The liquid and plastic limits, and the plastic index of the soil are improved upon modification, to 27.4, 17.7, and 9.7%, respectively. The unconfined compressive strength and hydraulic conductivity were significantly increased and reduced, respectively. In addition, there was a reduction in the rate of disintegration by water, while the water resistance of the soil was improved. X-ray diffraction, Fourier transform infrared, and thermogravimetry/differential scanning calorimetry studies reveal that the improved properties arise through physical processes between the sticky rice paste and the soil. Scanning electron microscopy reveals that dispersed branched-chain sticky rice-paste molecules extensively infiltrate the surfaces of the soil particles on the nanoscale and become attached to them to form a good adhesive colloid that solidifies the soil particles after water evaporation, resulting in a compact structure.     

Confirmation and Weight Management: Predicting Effective Levels of Acceptance and Challenge in Weight Management Messages

The current study employed a confirmation perspective to assess individuals’ perceptions of weight management messages. Confirmation was conceptualized as being comprised of two components: acceptance and challenge. Building on the main theoretical premise that messages higher in acceptance and challenge would be perceived as more effective in promoting healthy behaviors than messages lower in these components, we assessed how the relationships between the two components and message effectiveness varied by individuals’ characteristics. Specifically, we examined body self-esteem, readiness to change, weight locus of control, motivations for weight management, and communication satisfaction with weight management conversations as potential moderators. Results indicated that, as hypothesized, messages higher in acceptance and messages higher in challenge were perceived as more effective. In addition, body self-esteem, certain stages of readiness to change, and communication satisfaction interacted with acceptance to predict effectiveness, and internal locus of control and appearance and strength motives interacted with challenge to predict effectiveness. These results, in combination, suggest that although messages high in either component of confirmation were perceived as generally effective in motivating healthy behaviors, optimal levels of acceptance and challenge may vary by certain individual and relational characteristics. Practical and theoretical implications are discussed.     

Setting the agenda for environmental news: The effects of media and public characteristics

This study examined the relationship between different media agendas and public agendas in the agenda‐setting process. The local and regional media agendas for environmental news in the Lansing, Michigan, area were exactly the same. It was also found that respondents could accurately assess media issue emphasis when they were asked to do so.     

Facial Similarity Mitigates the Persuasive Effects of Source Bias: An Evolutionary Explanation for Kinship and Susceptibility to Influence

This research examined how the interaction between a source's facial similarity to message targets and communicated bias affects audience persuadability. We used an evolutionary explanation to hypothesize that biased sources would elicit less favorable attitudes than unbiased sources for dissimilar sources, but that this difference would be absent for similar sources. Predictions were supported by results from a 2 (facial similarity) × 2 (source bias) experiment, in which an unrecognizable percentage of participants' photographs (n = 94) was digitally morphed with a source's face to act as a kinship cue. Further, structural equation modeling demonstrated a direct effect of facial similarity on attitude independent of mediation by source liking and appraisals, providing further evidence that susceptibility to influence from facially similar sources may have evolutionary origins.     

Dump-and-Chase: The Effectiveness of Persistence as a Sequential Request Compliance-Gaining Strategy

Two field experiments were performed assessing the effectiveness of the dump-and-chase, a compliance-gaining technique employing strategic persistence. These two experiments demonstrate the effectiveness of the dump-and-chase relative to other known compliance-gaining techniques. Experiment 1 found the dump-and-chase more effective than pooled data from the door-in-the-face and placebic information technique. Experiment 2 found the dump-and-chase more effective than the door-in-the-face, placebic information, and foot-in-the-door. The dump-and-chase produced consistently higher compliance-gaining proportions across experiments. Moreover, because the contextual features of two experiments differed substantially, the effect was robust to important contextual differences.

Emotional Responses to Televised PSAs and Their Influence on Persuasion: An Investigation of the Moderating Role of Faith in Intuition

This research examines the influence of message recipients' emotional responses to televised PSAs on their attitudes toward the advocated issues. Integrating the affect-as-information paradigm and Epstein's cognitive-experiential self-theory, this research hypothesizes that message-induced emotions will have a greater influence on persuasion for individuals who have a strong faith in intuition than for those who have a weak faith in intuition. Overall, the main hypothesis was partially supported. There is some indication that faith in intuition moderates the influence of message-induced emotions on persuasion such that people with a stronger faith in intuition tend to rely more on experienced emotions when making judgments. The moderating effects of faith in intuition, however, appear to be confined to specific PSAs and discrete emotions.     

The Door-in-the-Face Persuasive Message Strategy: A Meta-Analysis of the First 35 Years

A random-effects meta-analysis was undertaken to examine the effectiveness of the Door-in-the-Face (DITF) persuasive message strategy on compliance. Results indicate an overall significant effect of the DITF strategy on verbal compliance (k=78, r=.126), but an insignificant effect for behavioral compliance (k=39, r=.052). In terms of verbal compliance, the DITF strategy works significantly better than controls for different samples, across varied communication media, and for prosocial causes. Additionally, the DITF technique is more successful than controls for volunteering/research than other target behaviors (e.g., monetary donation). For both verbal and behavioral compliance outcomes, the toughness (measured as amount of baseline compliance) of the donation context negatively predicted the magnitude of the DITF effect. It is argued social responsibility theory best accounts for observed moderator factors.

From Belief-Importance to Intention: The Impact of Framing on Technology Adoption

The current research integrates and extends the notion of issue framing to the study of innovation-diffusion and explores the influence of frames on the formation of beliefs about a technological innovation. Frames reflecting a new note-taking software's attributes were developed based of the Unified Theory of Technology Adoption and tested within a randomized experiment. Results revealed a significant and unique framing effect. Frames influenced the psychological importance attached by adopters to specific attributes or beliefs about the technology rather than their generalized beliefs about technology. These salient beliefs, in turn, shaped the individual's expectations from technology and influenced their decision to adopt it. Of the frames tested, extrinsic frames that highlighted social influence factors had a stronger effect. This effect was strongest when the frame presents negative extrinsic information about the innovation. In contrast, frames that positively highlighted performance and ease of use of the innovation tended to create higher expectations from the innovation, get compared to the feature-based triggers in the innovation, and get rejected by users. Interestingly, though there was an attenuation of framing effects across all conditions after one week of actual technology use, the framing effect endured and significantly influenced perceptions about the technology's performance. The results suggest the possibility of using small changes in content to significantly alter the meaning attributed to a technology and powerfully influence its rate of adoption over time.     

When less is more and more is less: The paradoxical metacognitive effects of counterarguing

ABSTRACT

According to the cognitive perspective, the generation of counterarguments is a key obstacle to persuasion. Following the metacognitive view, however, the experience of difficulty that accompanies increased counterarguing may benefit persuasion. These two contrasting predictions were evaluated in two experiments (N₁?=?392; N₂?=?210) by manipulating the instructions of thought-listing tasks following exposure to a testimonial that advocated for Physician-Assisted Suicide. Results for participants low-in-NfC supported the cognitive prediction, whereby generating many counterarguments (7) led to less favorable attitudes toward PAS, whereas fewer counterarguments (2) engendered more positive attitudes. In contrast, among participants high in NfC, increased counterarguing (7) resulted in more favorable attitudes toward PAS, while fewer counterarguments (2) were translated into greater opposition.     

Changes in Advertising Strategies During an Economic Crisis: An Application of Taylor's Six-Segment Message Strategy Wheel

Between 2005 and 2009 financial service organizations in the United States altered their advertising messages in response to changing economic conditions brought about by a sustained recession. This analysis of print magazine advertisements for banks, credit cards, investment firms, and insurance providers demonstrates that financial service advertisers shifted away from transformational approaches in favor of informational approaches. Credit card companies were slower to change their strategies than were bank, investment, and insurance companies. The results of this analysis support the argument that advertising serves the role of providing market information and that the nature of such information is determined by economic conditions.     

The Personal Organization of Electronic Mail Messages in a Business Environment: An Exploratory Study

In the business world, electronic mail (e-mail) has emerged as a widely used communication tool for transmitting knowledge between managers. As a result, these messages will require organization should future access to this trapped knowledge be expected and desired. A manager's e-mail classification scheme should be logically constructed in anticipation of future need, but future need may be driven by the information needs of other people within the organization such as superiors or subordinates. This researcher explored the nature of e-mail classification and documented the emergence of a high utility, multi-stage, classification process. The resulting framework consists of four categories that help explain how managers classify business-related e-mail. The first category reflects the immediate needs of the manager and the behavior of establishing relationships between messages. The second category reflects the manager's use of the in-box as a crude task-manager. The third category aligns with the manager's interest in scanning the environment. The fourth category reflects the managers perceived future need for the captured knowledge. The subjects rejected automatic classification and preferred an enumerative scheme. The researcher illustrates how the results of this study align with Marco and Navarro's three stage cognitive process that leads to stored knowledge (On some contributions of the cognitive sciences and epistemology to a theory of classification, Knowledge Organization, 20(3), 126–132). The cognitive processes that underlie classification are an essential component in understanding knowledge organization and have remained in focus during this study.
