Overtuigende teksten: Onderzoek en ontwerp (2e ed.)

Hoe komt het dat woorden gedrag kunnen beïnvloeden? En waarom mislukt dat vaak? Overtuigende teksten biedt een overzicht van theorieën over de invloed van taal, tekst en beeld binnen het overtuigingsproces en van het empirisch onderzoek hiernaar. De auteurs koppelen onderzoek naar de invloed van deze boodschapkenmerken aan verschillende verwerkingsprocessen. Ook besteden zij aandacht aan automatisch en beredeneerd gedrag en de rol van cultuurverschillen in het overtuigingsproces. Tot slot gaan zij in op het ontwerpen en pretesten van persuasieve teksten, waarbij zij een overzicht geven van methoden en instrumenten die je kunt inzetten om relevante informatie over de doelgroep te verzamelen. Elk hoofdstuk sluit af met praktische opgaven.

Reasoning and argumentation

Although argumentation plays an essential role in our lives, there is no integrated area of research on the psychology of argumentation. Instead research on argumentation is conducted in a number of separate research communities that are spread across disciplines and have only limited interaction. Cognitive psychological research on argumentation has focused mostly on argument as a reason, and argument as structured sequence of reasons and claims. A third meaning of argument has been neglected: argument as a social exchange. All meanings are integral to a complete understanding of human reasoning and cognition. In this special issue, we present work that is relevant to all these three meanings of argument. The papers by Heit and Rotello (on the effect of argument length on inductive reasoning), by Harris, Hsu and Madsen (on a Bayesian test of the ad Hominem fallacy), and by Thompson and Evans (on belief bias in informal reasoning tasks) focus on arguments as reasons. By contrast, the contributions by Van Eemeren, Garssen, and Meuffels (on the reasonableness of the disguised abusive ad hominem fallacy), by Hoeken, Timmers, and Schellens (on argument quality and convincing arguments), by Mercier and Strickland (on how arguments can be evaluated from audience reactions), and by Bonnefon (on generating consequential arguments) deal intrinsically with situations where there are multiple protagonists in a communicative exchange. By including these papers, by researchers from a range of theoretical backgrounds, this special issue underlines the breadth of argumentation research as well as stresses opportunities for mutual awareness and integration.

Reasoning and argumentation: Towards an integrated psychology of argumentation

Although argumentation plays an essential role in our lives, there is no integrated area of research on the psychology of argumentation. Instead research on argumentation is conducted in a number of separate research communities that are spread across disciplines and have only limited interaction. With a view to bridging these different strands, we first distinguish between three meanings of the word “argument”: argument as a reason, argument as a structured sequence of reasons and claims, and argument as a social exchange. All three meanings are integral to a complete understanding of human reasoning and cognition. Cognitive psychological research on argumentation has focused mostly on the first and second of these meanings, so we present perspectives on argumentation from outside of cognitive psychology, which focus on the second and third. Specifically, we give an overview of the methods, goals, and disciplinary backgrounds of research on the production, the analysis, and the evaluation of arguments. Finally, in introducing the experimental studies included in this special issue, which were conducted by researchers from a range of theoretical backgrounds, we underline the breadth of argumentation research as well as stress opportunities for mutual awareness and integration.

The effect of communication modality on the persuasiveness of hedges and pledges

The claim that a product advertisement aims to put forward is usually related to the product benefits. In an abstract way, claims have formats such as ‘Product X has benefit Y’ or ‘Product X leads to benefit Y’. Advertisers do not necessarily express such product claims explicitly. Claims may be left implicit because readers can easily construct them personally. If product claims are expressed explicitly, advertisers sometimes use hedges or pledges, which mark the probability that the promised benefit will occur. A hedge marks a claim as moderately probable (e.g., In most cases), whereas a pledge marks a claim as highly probable (e.g., In all cases). Experimental research to date (see §2) has shown that these probability markers are equally persuasive, and that they are not more persuasive than claims without such markers. Berney-Reddish and Areni (2005) argue that research should examine hedges and pledges in different communication modalities because people have been shown to process information differently in various communication modalities, such as print, audio, and the Internet. The present study therefore compares the persuasiveness of hedges and pledges in advertising claims in print and audio, and examines how these markers are processed in the two communication modalities.

The effects of hedges and pledges in advertisements for high and low reputation brands

Claims in advertising may vary in their use of probability markers that signal the degree to which the claim is true. Experimental research has compared hedges (which mark a claim as moderately probable) and pledges (which mark a claim as very probable). This research has generally neglected the proponent of the claims: the brand. There are reasons to believe that the brand behind the advertising affects to what extent people are persuaded by advertising claims. In two studies it was therefore investigated whether the reputation of the brand affects the persuasiveness of hedges and pledges. It was expected that hedges would be more persuasive for low-reputation brands, whereas pledges would be more persuasive for high-reputation brands. This expectation was tested in two experiments. In Study 1, hedges and pledges were compared in an ad that was provided after information about a brand’s reputation. In Study 2, hedges, plegdes and no markers were compared in an ad in which the brand’s reputation was incorporated. Both studies did not find empirical support for the hypothesis. In Study 1, hedges and pledges were found to be equally persuasive; in Study 2, pledges were found to be more persuasive than hedges.
