Stimuli
OSF
We focused on drinks because these items show marked individual preferences, their consumption can be reliably measured due to reduced variability in packaging size, and the limited number of brands enables the generation of stimuli matching real-world presentations.The stimuli were drinks marketed in Switzerland: 43 pictures of unhealthy drinks, 7 pictures of water bottles, and 6 pictures of aromatised water bottles taken by a professional photographer. The pictures can be downloaded on the OSF study page (10.17605/OSF.IO/5ESMP).
