    Resumen:
    In two experiments, rats received exposure to a compound consisting of a solution of salt plus a distinctive flavor (A), followed by an injection of furo-doca to induce a salt need. Experiment 1, established that this procedure successfully generated a preference for flavor A in a subsequent choice test between A and water. Experiment 2 used this within-event learning effect to investigate generalization, testing the rats with both A and a novel flavor (B). For different groups the interval between the training phase and the test phase was varied. Subjects tested immediately after training showed a steep generalization gradient (i.e., a strong preference for A, and a weak preference for B). Subjects given a 14-day retention interval showed a flattened gradient, a reduced level of preference for A and an enhanced preference for B. These results are interpreted in terms of changes in stimulus representations over the retention interval that act to reduce the effectiveness of the distinctive features of stimuli (the features that are necessary to ensure discrimination between them).

    • The Effect of Additional Exposure to the Unique Features in a Perceptual Learning Task Can Be Attributed to a Location Bias 

      Recio, Sergio; Iliescu, Adela; Berges, German; Gil-Nájera, Marta (1); de Brugada, Isabel (Journal of Experimental Psychology-Animal Learning and Cognition, 04/2016)
      It has been suggested that human perceptual learning could be explained in terms of a better memory encoding of the unique features during intermixed exposure. However, it is possible that a location bias could play a ...
    • Motivational factors controlling flavor preference learning and performance: Effects of preexposure with nutritive and nonnutritive sweeteners 

      Gil, Marta (1); de Brugada, Isabel; Hall, Geoffrey (Elsevier B.V., 2021)
      In three experiments thirsty rats were given exposure to a sweet solution (saccharin in some experiments, sucrose in others) prior to consuming a compound of the sweet substance and almond flavoring. Preference for that ...
    • Effect of exposure to similar flavours in sensory specific satiety: Implications for eating behaviour 

      González, Ana; Recio, Sergio Andrés; Sánchez, Jesús; Gil, Marta (1); de Brugada, Isabel (Appetite, 08/2018)
      Sensory-specific satiety (SSS) refers to a decline in pleasantness of eaten foods in comparison to other noningested meals. Although SSS is specific to the eaten food, it can also generalize to other meals that share similar ...
