The group gathers a large range of expertise: eating behaviour, sensory evaluation, developmental and cognitive psychology, ethology, nutrition and statistics.
Despite different public policies aiming at nutritional prevention of health, eating behaviour still leads, for many consumers, to diets quite apart from the recommendations. In this context, it is important to understand better how eating behaviours are formed in the early years of life, how they evolve along the life course, and how they are associated to malnutrition in the elderly. This knowledge could help to identify potential levers of eating behaviour modification towards a healthier diet while maintaining the pleasure to eat.

Key words : infants, children, elderly people, sensory perception, learning, feeding practices, overweight, malnutrition.

Thematic : We study sensory and cognitive determinants of eating behaviour (preferences, choices, intake), their development during childhood and their dynamics along the life course.

Research group in detail Open all the tabs

Our aim is to understand better the determinants of eating behaviours taking into account sensory characteristics and nutritional properties of foods, and also the previous experiences, the psychological and cognitive characteristics of individuals.

Theme 1 : Early development of food preferences and eating behaviours

  • - Relative effect of different factors that could explain food preferences and eating behaviours during early childhood on the basis of cohort data and statistical modelling approaches.
  • - Relative efficiency of different learning mechanisms evaluated thanks to interventional studies.
  • - Role of exposure on attraction to sweet foods and brain responses to sweet solutions.
  • - Evolution of the control of food intake in infancy and early childhood: effect of maternal feeding practices.
  • - Role of feeding practices, sensory reactivity and experiences on likes and dislikes and on neophobic behaviours.

Theme 2 : Role of perceptive and cognitive mechanisms on food preferences and eating behaviours

  • - Role of the sensory characteristics
  • - Role of implicit mechanisms (priming)
  • - Effect of context and information

Theme 3 : Effect of eating behaviour on the nutritional status of elderly individuals

  • - Characterization of the variability of preferences and food practices within the elderly population
  • - Role of the sensory, psychological, and social factors on the decrease of appetite
  • - Development of foods adapted to the chemosensory and oral capacities of elderly people

Sensory evaluation

- Hedonic measurements for different foods or sensory stimuli
- Qualitative approaches (in-depth interviews, focus groups) and quantitatives approaches (questionnaires)
- Psychophysics: measurements of gustatory and olfactory sensitivities

Ethology

Behavioural measurements: in usual contexts of consumption (at home, in nurseries, in school canteens, in nursing homes, …) or in the lab.

Psychology

Experimental psychology tests: association tasks, categorizations tasks, ranking, priming paradigms…

Physiology

Measurements of brain activations in response to visual or gustatory stimuli by electroencephalography or by functional magnetic resonance imaging (fMRI).

Statistics

Statistical modelling of preferences or behaviours

Human model

Our research aims at studying human eating behaviour all along the life course, with a specific focus on childhood (infant, toddler and children) and on the ageing population (living at home or in nursing homes).

Edulia project : Marie Sklodowska- Curie grant agreement No 764985

Edulia responds to the urgent need of EU society to promote healthier eating from childhood. Based on the relations of sensory perception, pleasure, food choice and food behaviour, the project will look for new approaches to drive children to like and actively choose healthy foods, developing healthier habits. Two PhD students are involved in this project: Kaat Philippe studies the links between feeding parental practices and young children's eating behaviours and Sofia de Rosso studies the effect on parental feeding behaviors of disseminating recommendations on good practices for establishing healthy eating habits from an early age.

IMPLICEAT project : Project-ANR-17-CE21-0001

The main scientific objective of IMPLICEAT is to better understand food choice decision mechanisms in normal weight, overweight and obese adults. The central hypothesis is that people cognition and eating behaviour, in particular food choices, are not only influenced by conscious perception of cues but also by non-conscious/non-attentive exposure to these cues. IMPLICEAT provides unique opportunities, at a technical level (1) to develop innovative methodologies both at the behavioral level as in neuroscience; at a societal level (2) to disseminate, towards public authorities, substantial findings based on implicit approaches, adaptable in different socio economic contexts, in order to highlight links between food choice, health and implicit cognition
