The relationship between the developmental level of persuasive strategies and their effectiveness

Research on the development of persuasive communication skills has described the emergence of four basic strategies in persuasive messages. This study includes two experiments to assess the role these strategies play in the process of gaining compliance. In both, college students received messages requesting they volunteer for an experiment and advocating compliance. Messages differed in the level of strategic adaptation of the compliance‐gaining appeal they offered. In general, form of request (supported versus unsupported) and content of specific message appeals influenced compliance, but level of strategic adaptation made little or no contribution to message effectiveness.     

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.     

An Experimental Investigation of Social Identification on College Student Organ Donor Decisions

This investigation examined whether persuasive organ donation messages that target individuals’ identification with a salient social group will be more effective in encouraging these individuals to become organ donors than will information-only persuasive messages. Participants were randomly assigned to view one of two pro-organ donation messages, both of which included basic information about organ donation (need, number of registered donors, etc.) while one also targeted social identity. Findings indicate that individuals exposed to a social identification message were more likely to click a link that allowed them to officially register as organ donors. These results offer support for the utility of social identification as a health communication campaign strategy for increasing organ donation.     

Testing the persuasiveness of evidence: Combining narrative and statistical forms

This study provides an experimental test for the conclusions of the Allen and Preiss (1997) meta‐analysis that statistical evidence is more persuasive than narrative evidence. This investigation extends that finding to consider the case where a message combines statistical and narrative evidence to determine if a combination of evidence is more effective than a single form of support. This investigation using 15 messages and 1,270 participants finds that a message combining narrative and statistical evidence is more persuasive than a message using either narrative or statistical evidence alone.     

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.     

Intertribal dance and cross cultural communication: Traditional powwows in Ohio

Greater fear arousal is associated with greater engagement with persuasive messages, and negative information and events are more potent than their positive counterparts. Hence loss-framed persuasive appeals, which emphasize the undesirable outcomes of noncompliance with the communicator's recommendations, should elicit greater message processing than do gain-framed appeals, which emphasize the desirable outcomes of compliance. But a meta-analytic review (based on 42 effect sizes, N = 6,378) finds that gain-framed messages engender slightly but significantly greater message engagement than do loss-framed messages. This effect is apparently not a result of whether the appeals refer to obtaining or averting negative (e.g., “skin cancer”) rather than positive (e.g., “attractive skin”) outcomes.     

The Suasory Force of Sticky Messages: An Application to the Application of Sunscreen

Stickiness refers to the set of persuasive message properties: simple, unexpected, concrete, credible, emotional, and stories (SUCCES). Heath and Heath (2007) argue that a sticky message is expected to be more memorable and hence more persuasive than a non-sticky message. A 2 (sticky v. non-sticky message) x 3 (pretest v. posttest v. delayed test) longitudinal experiment is employed to examine the persuasiveness of sticky messages on applying sunscreen. Results of a mixed model analysis of variance show that the sticky message produces attitudes and behaviors more favorable to the message recommendation than the non-sticky message. Specifically, a time × message induction non-additive effect was found, which sustained only in the sticky message condition across time. Despite this interesting effect, its explanation remains elusive.     

Perceived Message Effectiveness Measures in Tobacco Education Campaigns: A Systematic Review

ABSTRACT

Target audience ratings of the likely impact of persuasive messages, known as perceived message effectiveness (PME), are commonly used during message development and selection. PME is also used to examine receptivity of messages after they are fully developed or deployed. Despite this, we know little about the conceptual and methodological characteristics of extant PME measures used in the literature. We conducted a systematic review of tobacco education video, print, and audio campaign studies to examine conceptual and methodological characteristics of PME measures. One hundred twenty-six PME measures from 75 studies conducted in 21 countries with more than 61,000 participants were reviewed. Results indicated considerable variability in measures’ focus on general perceptions of a message (i.e., message perceptions) vs. perceptions of expected message effects (i.e., effects perceptions). Considerable variability was also found on underlying persuasive constructs, use of referents, and referencing of behavior in PME items and measures. We conclude with several recommendations for future research on PME measurement and validation.     

Automatic responses,target resistance,and the adaptation of compliance-seeking requests

Based upon politeness theory and a cognitive rules perspective, it is argued that anticipated resistance to a persuasive message should effect compliance-seeking message behavior. Using controlled interviews to elicit persuasive messages, results indicate that persuaders used a greater number of strategies when confronting a positively predisposed target who refused to comply. Beyond an initial opening gambit, negative sanctions were employed more extensively against positively predisposed targets. Overall, a pattern of compliance-gaining behaviors involving a gradual shift to negative sanctions was observed. The findings are explained in light of current perspectives on information processing, possibly shedding light on past failures to find evidence of strategic adaptation based on situational factors.     

Using the Emotion-in-Relationships Model to Predict Features of Interpersonal Influence Attempts

This paper considers how the Emotion-in-Relationships Model (ERM), a theory designed to predict people's experience of emotion, might explain persuasive messages. A study was conducted in which 248 individuals simulated leaving a date request voicemail message. Consistent with ERM, people's perceptions of interference from partners were positively associated with appraisals of self threat and relationship threat and negatively associated with the fluency of messages. People's perceptions of facilitation from partners were positively associated with identity management strategies, positive politeness, and the affection of messages. These results persisted after covarying relationship satisfaction. Taken together, the findings shed light on the strengths and weaknesses of ERM as a theory of interpersonal communication.     

Construct comprehensiveness and cognitive complexity as predictors of the number and strategic adaptation of arguments and appeals in a persuasive message

Subjects differing in construct comprehensiveness and cognitive complexity wrote persuasive messages directed at a fictitious target person and gave written justifications for each argument or appeal used in their messages. Messages were scored for number of appeals used and appeal justifications were scored for the degree of strategic adaptation to the message target they reflected. Construct comprehensiveness correlated positively and significantly with level of strategic adaptation; cognitive complexity correlated positively and significantly with number of appeals used and level of strategic adaptation.     

An uninformed electorate: identity-motivated elaboration,partisan cues,and learning

ABSTRACT

A deliberative democracy is reliant on an informed electorate discussing issues and presenting persuasive arguments. Individuals acquire information from exposure to political messages. Partisan cues, however, undermine learning outcomes. The current study experimentally examines the social cognitive processes that underlie this learning process. Integrating the social identity theory, elaboration likelihood model, and the theory of motivated reasoning to construct the theoretical concept of identity-motivated elaboration, the results indicate that partisan social identities motivate biased processing of new information, which subsequently influences the valence of elaboration. Positively and negatively valenced elaboration are situated as mediating variables in the structural model, which predicts learning from a persuasive political message. The current study extends the partisan social identity hypothesis to the elaborative and learning outcomes of political messages.     

Anger,fear, uncertainty,and attitudes: a test of the cognitive-functional model

The cognitive-functional model of discrete negative emotions and attitude change (CFM; Nabi, 1999) attempts to bridge the theoretical gap between “emotional” and “rational” approaches to persuasion by focusing on how emotions motivate attention to and processing of persuasive messages. As a first test of the CFM, this study explored the effects of 2 emotions, anger and fear, and 2 levels of expectation of message reassurance, certainty and uncertainty, on attitudes toward domestic terrorism legislation. Results supported a main effect for emotion type, suggesting that anger promotes deeper information processing than fear, and a main effect for reassurance certainty level, with uncertainty promoting deeper information processing. The expected interaction between emotion type and reassurance expectation level was not found. Implications of these findings for the model and persuasion research generally are discussed.     

Visual Assertions: Effects of Photo Manipulation and Dual Processing for Food Advertisements

In our media landscape, consumers view a plethora of messages with visual assertions, created through postproduction photo manipulation, which communicate meaning at-a-glance. These visual assertions are processed initially and directly and greatly influence how consumers think, feel, and behave. Yet the impact of visuals, which likely color all processing, is not incorporated in persuasive message processing models. Using dual processing models from multiple disciplines as a theoretical foundation, this study demonstrates through two experiments that the effects of photo manipulation, as visual assertions, in food advertising increased consumers' perceptions of healthfulness, positive attitudes, and purchase intentions. Dual processing models for persuasive messages should be extended to account for the initial, influential visual processing of implied assertions, often manipulated during postproduction.     

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.     

Fear appeal messages affect accessibility of attitudes toward the threat and adaptive behaviors

Fear appeals have long been used in persuasive messages to motivate people to perform adaptive behaviors. This research explored the influence of a fear appeal message concerning breast cancer on attitude accessibility. Messages advocating the efficacy of breast self‐examinations increased the accessibility of attitudes toward the adaptive behavior. Further, the accessibility of participants' attitudes toward the adaptive behavior predicted behavioral intentions to perform breast self‐examinations. Attitudes toward the threat became less accessible after exposure to a high fear‐arousing message, however. Analyses suggest that defensive reactions to the fear‐inducing message mediate the influence of the message on the accessibility of the attitudes toward breast cancer. Implications of these findings for models of fear appeals are discussed.     

Doctoral dissertations in speech: Work in progress, 1952

Prior research on comforting communication from the constructivist perspective has employed a hierarchical system of message analysis to classify different comforting strategies; within this system, messages are scored for the extent to which they explicitly acknowledge, elaborate, and legitimize the feelings of distressed others. The present paper reports two studies assessing the extent to which naive actors' perceptions of comforting strategy sensitivity, effectiveness, and quality correspond with the formal analysis of comforting strategy sophistication embedded in the constructivist hierarchical coding scheme. In the first study, 73 female college students interacted with a female confederate who feigned distress over having recently been dropped by her long‐term boyfriend. These interactions were videotaped and content analyzed; in addition, both the confederate and an experimental observer rated participants' behaviors for sensitivity. Results indicated that participants employing a greater proportion of theoretically sophisticated comforting strategies were perceived as behaving more sensitively toward the confederate. In the second study, 148 college students were presented with lists of preformulated comforting strategies derived from the constructivist hierarchy and were asked to rate these strategies for “sensitivity” and “effectiveness” and to rank order them in terms of overall quality. Results indicated that respondents rated and rank ordered the strategies in a manner very consistent with the constructivist hierarchical ordering of comforting strategy types: The constructivist ordering of the strategies explained over 95% of the variance in respondents' ratings and rank orderings.     

Effectiveness of health messages to change women's thin-ideal and unhealthy weight control intentions: Connecting social norms and social networks approaches

The thin-ideal is becoming increasingly dominant among women in Eastern Asian countries such as China and South Korea. The internalization of the thin-ideal leads to body image disturbance and unhealthy weight-control behaviors. Based on the social networks and social norms approaches, this study tests the effectiveness of normative messages in reducing women's internationalization of the thin-ideal and weight-control intentions through an experiment among female college students in China. It investigates how the following three factors: content of normative message (psychoeducational or feminist), source of the message (strong ties or weak ties), and characteristics of the recipients (self-weight evaluations) influence women's body image and weight-control intentions. Results of this study suggest that normative messages with a psychoeducational approach delivered through strong ties are more effective in decreasing women's internalization of the thin-ideal than the same message delivered through weak ties. In contrast, normative messages with a feminist approach delivered through weak ties are more effective in reducing women's internalization of the thin-ideal and unhealthy weight-control intentions than the same messages delivered through strong ties. There is an interaction effect between message content and recipients' self-weight evaluation. The theoretical and practical implications of this study are discussed.
