Spatial cues are relevant for learned preference/aversion shifts due to amino-acid deficiencies.

Rats are able to choose appropriately between two versions of a novel diet, when one is amino-acid devoid and the other corrected. Recognition of the deficiency has been reported to occur within hours and to initiate a strong conditioned aversion. For that purpose the rat can use either oro-sensory cues or another alternative as the conditioned stimulus (CS) with which to associate the unconditioned stimuli (US) of either the adequate diet or the devoid diet. The present investigation was designed to determine whether rats have the ability to use place as a cue in amino-acid preference/aversion. In order to avoid interfering with any other than spatial sensory discrimination between the dev…

Providing choice and/or variety during a meal: Impact on vegetable liking and intake

Food choice is defined as providing the opportunity for an individual to select the food he or she wants to consume while food variety is defined as providing an individual with foods that differ on at least one sensory characteristic. Literature shows that providing food choice or providing food variety may increase meal enjoyment and food intake. However, these two factors have been mainly investigated separately, while they may actually co-occur in real-life settings. In fact, in many out-of-home catering situations, individuals have the possibility to choose as many dishes as they desire from among different proposals for their meal. The aim of the present study was to assess the impact…

Providing choice and/or variety on vegetables: What impact on food intake?

On the one hand, a choice situation gives an individual a sense of freedom, autonomy and control over the environment, which triggers higher intrinsic motivation and higher satisfaction (Deci and Ryan, 1985). Indeed, it has been demonstrated that a choice situation elicits higher food intake in a meal context (Rohlfs Domínguez et al., 2013; Parizel et al., 2015). On the other hand, providing variety has been demonstrated to enhance food intake. Rolls et al. (1981) argued that providing variety during a meal prevents the onset of specific sensory satiation which refers to the declining satisfaction generated by the monotonous consumption of a certain food. However, in an out-of-home catering…
