- Dispositional beliefs regarding “affect as information” determine the perception of persuasive self-efficacyPublication . Garcia-Marques, Teresa; Loureiro, FilipeAbstract: In this paper, we approach the relationship between believing that affect informs about the validity of a claim and believing that one persuasive strategy will be more or less efficient in changing one’s own attitude. In one study, participants were asked to select from a set of features of a persuasive context those they perceived to have more persuasive power. Results showed that these selections were clearly clustered in two groups, suggesting that individuals tend to select either more cognitive features or more experiential affective features. Individual measures regarding participants’ need for cognition and faith in intuition did not explain the tendency to select more one type of cluster or another, but this selection was determined by how much people generally believe that affect informs about the validity or goodness of a claim.
- More than meets the gut: A prototype analysis of the lay conceptions of intuition and analysisPublication . Loureiro, Filipe; Garcia-Marques, Teresa; Wegener, Duane T.Using a prototype approach, we assessed people’s lay conceptions of intuition and analysis. Open-ended descriptions of intuition and analysis were generated by participants (Study 1) and resulting exemplars were sorted into features subsequently rated in centrality by independent participants (Study 2). Feature centrality was validated by showing that participants were quicker and more accurate in classifying central (as compared to peripheral) features (Study 3). Centrality ratings suggested a single-factor structure describing analysis but revealed that participants held lay conceptions of intuition as involving two different types of processes: (1) as an automatic, affective, and non-logical processing, and (2) as a holistic processing that can assist in problem-solving. Additional analyses showed that the centrality ratings of intuition’s facets were predicted by participants’ self-reported intuitive style, suggesting intuition is differently perceived by intuitive and non-intuitive people. We discuss the implications of these results for the study of intuition and analysis.
- Norms for 150 consumer products: Perceived complexity, quality objectivity, material/experiential nature, perceived price, familiarity and attitudePublication . Loureiro, Filipe; Garcia-Marques, Teresa; Wegener, RebekahConsumer products are widely used as stimuli across several research fields. The use of consumer products as experimental stimuli lacks, however, the support of normative data regarding product features variability. In this work, we provide a first set of norms for people's perceptions of 150 consumer products regarding six relevant dimensions: product perceived complexity, quality objectivity, material/experiential nature, perceived price, familiarity and attitude. Products available in this normative database showed good overall distribution across the range of the dimensions evaluated. Obtained correlations between some of these dimensions provided evidence of how they can be confounded across products, further justifying the need to control for these dimensions. These norms should aid future research by allowing researchers to select products according to specific attributes and achieve appropriate experimental control. The norms here provided should also aid consumer behavior practitioners (such as marketers and advertisers) by providing insights as to how consumers perceive products along relevant dimensions.
- A Cognitive toolbox for persuasion. Perceived diagnosticity and persuasibility bias of persuasive featuresPublication . Garcia-Marques, Teresa; Loureiro, FilipePersuasive features such as argument quality, source expertise, support, affect, consensus, source likability, and source attractiveness are linked to mental rules that vary in their reliability in supporting the persuasive process. We address these features as cognitive tools available to support judgments, investigating their self-other perceived diagnosticity and persuasibility, and using self-other differences as an index of perceived bias. Results show that participants explicitly consider argument quality, source expertise, and support (number of arguments) as diagnostic of the validity of a claim. Such diagnosticity predicted perceived persuasibility, and self-other differences linked non-diagnostic features to bias. We further discuss the relevance of these findings for a more comprehensive understanding of the cognitive toolbox that supports persuasive influences.
