Impact of individual characteristics on the modulation of intensity perception, emotional reactions, and subjective liking and preference for fundamental taste mixtures
In a recent study, researchers aimed to determine if individual personality traits could affect prediction models of overall liking and preference rank towards basic taste solutions. Based on the results, it appears that personality traits, particularly extraversion and neuroticism, play a crucial role in the subjective experience of taste.
Extraversion, often associated with openness to new experiences and social eating, may increase preference for certain tastes or more complex flavor profiles. This trait can enhance the predictive accuracy of models for individuals high in extraversion by capturing their tendency towards novelty or social influences in taste liking.
On the other hand, neuroticism, linked to emotional instability and heightened sensitivity, may predict differential liking driven by emotional or stress-related factors affecting food perception and preference. Models incorporating neuroticism traits may better forecast preferences by accounting for mood-dependent variations in taste liking.
The study, which involved sixty-seven participants, found that emotional responses towards each sample were a significant factor in predicting overall liking and preference rank towards basic taste solutions for both clusters N (high neuroticism) and E (high extraversion). Autonomic nervous system measures, however, showed little contribution to the prediction model of overall liking for either cluster.
Participants rated the overall liking of the samples and ranked their preferences. Based on a hierarchical cluster analysis, they were classified into two clusters: cluster N (high neuroticism) and cluster E (high extraversion). Interestingly, participants in cluster N demonstrated a higher sensitivity to emotional responses when it came to predicting overall liking and preference rank towards taste samples.
The study's findings could have implications for the development of personalized taste prediction models, taking into account individual differences in personality traits, particularly neuroticism and extraversion. While the exact quantitative effects of these traits on prediction models of basic tastes are not detailed explicitly in the available sources, the broader nutritional psychology research supports that incorporating personality traits like extraversion and neuroticism improves the explanatory power of preference models by capturing psychological factors underlying taste preferences.
In conclusion, extraversion tends to correlate with openness to diverse tastes and social eating patterns, influencing preference rank. Neuroticism links to emotional factors affecting taste liking, introducing variability relevant for prediction. Models that include these traits can better predict overall liking and preference rank of taste solutions by encompassing individual psychological differences.

Science in the realm of health-and-wellness and mental-health is delving into eye tracking consumer research to understand individual preferences in taste solutions. This research could potentially reveal how personality traits like extraversion and neuroticism impact the subjective experience of taste through the lens of health and mental well-being.
