Repeatability in hedonic sensory measurement: a conceptual exploration

Liking and exposure: First, second and tenth time around

“…Köster and colleagues have discussed and explored stability of preferences in a number of experiments. Their finding led them to suggest that the repeatability of hedonic methods rather should be judged on basis of the stability of the change in preference of different, but comparable populations, rather than on the reliability of repeated measurements in the same population [2].…”

“…Köster and colleagues [2] briefly reviewed a number of contributions in the field. Several theories have been suggested, among them, 'Mere exposure theory' [3,4] which predicts that experience with stimuli leads to increased liking for them.…”

Advances in Consumer-Oriented Product Design Engineering of Foods

“…When asked to express their opinions or justify their actions in consumer questionnaires, individuals are asked to rationalise what could have been until then a non-rational reality. Koster (2003) has very eloquently explained the fallacies of consumer research methods by analysing their underlying assumptions under the light of cutting edge cognitive science knowledge, highlighting in particular five:…”

“…Individuals change in time-preferences, opinions, beliefs are continuously adjusted. A recent paper by Koster et al (2003) reviewed a series of works where individuals were exposed to a given stimuli over several sessions, and that have shown that less than half the individuals would stick to their first choice in subsequent sessions. conscious choice.…”

Stability in consumer responses to familiar and new chocolates during a period of exposure

“…to what extent do single hedonic measurements have a predictive value for future liking and choice? To answer this question several studies have been undertaken where the consumers are asked several times during exposure about their assessment of the products (Koster, Couronne, Leon, Levy, & Marcelino, 2003;Köster, Rummel, Kornelson, & Benz, 2001;Mustonen, Hissa, Huotilainen, Miettinen, & Tuorila, 2007;Kinnear & Kock, 2011;Stolzenbach, Bredie, Christensen & Byrne, 2013;SulmontRossé, Chabanet, Issanchou & Köster, 2008). Measurements of hedonic flexibility (Mustonen et al, 2007) and indices of performance (Naes et al, 2013) have also recently been developed for the purpose of measuring these aspects at an individual level.…”
