Koert van Ittersum's research while affiliated with University of Groningen and other places

... Previous research has shown that both, textual information and images can be effective mediums to trigger meat avoidance (e.g. Carfora et al., 2019;Kunst & Hohle, 2016;Koch et al., 2022). But textual information and images may differ in their potential to trigger cognitive dissonance. ...

... Moreover, by introducing the consumers' GSP as an underlying mechanism, we contribute to the knowledge of how PGW impacts BC. In so doing, our study enhances the nomological network of antecedents and consequences of consumers' GSP (Farooq and Wicaksono 2021;Koch, Bolderdijk, and van Ittersum 2021). Furthermore, by including consumers' EC, our study also enhances the readers' understating of why and when the association between PGW and BC will be amplified. ...

... That is, formal institutions, retailers and food producers, opinion leaders, and parents and caretakers should change social norms by increasing consumers' exposure to these foods and thus normalize them. If no longer perceived as deviant, edible insects and lab meat may reduce consumers' disgust response, thereby increasing purchase likelihood [1]. The importance of social norms is also illustrated for hemp food and fast food consumption [2,3]. ...

... Derived from mathematics and geometry [8], symmetry is a feature of classical aesthetics meaning uniformity and order. Preference for symmetry has been found in a large body of research, including natural selection research in response to biological signals in the nature, and even in irrelative contexts, such as aesthetic perception and exploratory behaviors [9,10]. In the context of food choices, symmetry or balance shape is found to be generally preferred better that their asymmetrical or unbalanced counterpart [11,12]. ...

... Furthermore, researchers can limit participants' shopping budget for each treatment. This might be particularly relevant for spending tracking experiments [29]. In this manner, it can be safeguarded that subjects invest reasonable effort into the shopping task and do not merely click through it. ...

... Endogenous motivation refers to teachers' behaviors that are spontaneous and stem from an interest in their work; exogenous motivation refers to teachers' efforts to engage in a certain area of work in order to reap certain outcomes. A series of studies have shown that internal motivation can promote positive behaviors and sources of motivation for achievement (Storch et al., 2020). Self-determination theory states that internal motivation not only has an impact on an individual's behavior and achievement, but also enhances happiness. ...

... In summary, attentional scope reflects an interaction between the valence of the emotion and the level of arousal associated with it, so nuancing the response in a particular situation. In humans, it has been shown that while the experience of having achieved monetary gains (low arousal positive emotion) is associated with a broad attentional scope, anticipating monetary gains (high arousal positive emotion) led to a narrowing of attentional scope 15 . Furthermore, even if individuals' attentional scope narrowed when they had been shown a picture of an appetizing dessert, it became even more narrow when arousal increased because they were led to believe that they would eat the dessert 16 . ...

... Indeed, prior literature found that elongated bottles can serve as a metaphoric cue to communicate about the healthiness of a food product to consumers (Van Ooijen et al., 2017). However, whereas an elongated shape enhances the perceived healthiness of healthy food products, it reduces the healthiness perceptions of unhealthy food products (Sheehan, Van Ittersum, Craig, & Romero, 2020). By extension, one may speculate that the "Healthy is Up" metaphor, which enhances the perception of healthy food products, might not contribute to improving the perception of unhealthy food products. ...

... Durch die explizite Fokussierung auf das Kauf verhalten statt dem Konsum, die bereits im Titel des Werks offenkundig wird (vgl. auchHoward und Sheth 1969, S. 3), deutete sich bereits seine Relevanz für BtoB und CtoCBeziehungen als weitere Bereiche des Marketings an (Bettman 2020).Darüber hinaus finden sich die Phasen der Kaufentscheidung, wie sie das Mo dell postuliert, in ähnlicher Form in vielen, neueren CustomerJourneyModellen wieder(Lee et al. 2018; vgl. Bettman 2020). ...

... Then we present the results of three experimental studies where we provide evidence of these two processes. We close with a discussion of the implications, directions for future research, and the larger theme of this work Wansink and van Ittersum 2016). ...
