The odors we perceive are mainly the result of mixtures of odorants that, however, are commonly perceived as single undivided entities; nevertheless, the processes involved remain poorly explored. It has been recently reported that perceptual blending based on configural olfactory processing can cause odorant mixtures to give rise to an emergent odor not(More)
The present study aimed to investigate olfactory anhedonia and olfactory negative alliesthesia in depressed patients. Two odorants, one with pleasant (vanillin), and one with unpleasant (butyric acid) hedonic valence were evaluated by 30 depressed inpatients and 30 controls (healthy subjects, matched by age and gender). Participants explored the hedonic(More)
This prospective study of food variety seeking among children was conducted between 1982 and 1999, with a follow-up in 2001-2002. Two- to three-year-old children were given a free choice of lunch foods in a nursery canteen. Their food choices were recorded and used to calculate early variety seeking scores, globally and by food group (vegetables, animal(More)
Vegetable intake is generally low among children, who appear to be especially fussy during the pre-school years. Repeated exposure is known to enhance intake of a novel vegetable in early life but individual differences in response to familiarisation have emerged from recent studies. In order to understand the factors which predict different responses to(More)
This study describes infant feeding practices among mothers from two European regions from the perspective of early sensory experiences. Two groups of mothers, one in Dijon , France (n=139), the other in Aalen , Germany (n=157) with infants aged 4-9 months were interviewed using a structured questionnaire. Clear between- and within-group differences in(More)
Introduction of solid foods is a major step in the establishment of eating behavior and is likely to affect children's health. However, the role of taste in acceptance of new foods, in particular in the first months of complementary feeding, is not fully understood and was the aim of the present study. Infants had to be in good health to participate (N=74).(More)
Current research in psychology suggests that unconscious processes influence a significant proportion of choices and decisions. To study the impact of a non-attentively perceived odour on food choices, we used a priming paradigm. We had previously shown that non-attentively perceived fruity odours could impact food choice intentions (on a menu card),(More)
The main objectives of the present study were to validate measures of young children's eating difficulties and maternal feeding practices in a French sample, as well as to assess the links between these practices and children's eating difficulties. Mothers (n=502) of French children aged 20-36 months completed four questionnaires that were validated using a(More)
Young and adult mammals are constantly exposed to chemically complex stimuli. The olfactory system allows for a dual processing of relevant information from the environment either as single odorants in mixtures (elemental perception) or as mixtures of odorants as a whole (configural perception). However, it seems that human adults have certain limits in(More)
Children's vegetable intake is below the recommended amounts. No studies to date have tested the relevance of using salt or spices to increase children's vegetable acceptance. Our objective was to compare the effect of repeated exposure (RE) and of flavor-flavor learning (FFL) on toddlers' acceptance of a non-familiar vegetable. Two unconditioned stimuli(More)
