At T1, when labels were presented without nutritional warnings, responses to the word association task were related to a description of the product category, expected sensory characteristics of the products, brand names, liking and eating occasions. However, when the labels werepresented with the warnings at T2, a significant increase in the frequency of mention of responses was observed within the categories Excessive content of sugar/fat/sodium, Not healthy, Diseases and negative health conditions, Rejection to consume, and Unexpected information. Results from the present work suggest that immediately after their implementation, nutritional warnings cause a salience bias that make excessive nutrient content and its negative health consequences more salient in consumers’ minds, especially in the case of products with a particular health-related connotation.
