Understanding the impact of perceived emotional valence of eco-labels for novel food products on consumer preferences, visual attention, and cognition - a multimodal study using EEG and eye tracking.
Review in Frontiers in psychology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Eco-labels are becoming an important marketing tool used to communicate these environmental attributes to consumers. However, little is known about how the perceived emotional valence of sustainability messaging influences the cognitive process underlying the purchase decision. Methods: This exploratory study investigates the effect of perceived emotional valence of eco-labels on consumer preferences, visual attention and neural processing for novel food products by integrating behavioral (choice data), eye-tracking and EEG data.. Results: Behavioral results indicated that eco-labels with high perceived positivity significantly increased purchase intentions, whereas labels with low perceived positivity did not. Eye tracking results revealed shorter fixation durations and lower number of fixations for high perceived positivity eco-labels, possibly suggesting greater processing fluency. The EEG results further revealed differences in P300 and LPP amplitudes for the different label categories. Integrated behavioral-neural analyses further showed that higher P300 amplitudes increased purchase intentions, whereas greater N200 amplitudes reduced purchase intentions for high-positivity labels. Conclusion: The results provide preliminary evidence showing that the effectiveness of eco-labels depends not only on what is communicated but how it is perceived. By conceptualizing valence as a continuum rather than a binary positive-negative construct, this study offers new hypotheses regarding the attentional and neural mechanisms through which sustainability communication shapes consumer preferences.
