AbstractOne of the most powerful influences on food intake yet identified is the presence of familiar others at an eating occasion: people eat much more when they eat with friends/family than when they eat alone. But why this is the case is unclear. Across two studies (Study 1: N = 98; Study 2: N = 120), we found that the mere anticipation of social interaction is all that is needed to promote the selection of larger meals, and that this occurs even when a person is alone when they make their decision. Adult women served themselves larger portions when they knew they were going to eat socially versus when they knew they were going to eat alone. These data suggest that how other people influence our food intake reaches beyond the specific eating context to affect pre-meal portion size decisions, suggesting that a fundamental shift is required in our thinking about social influences on eating.

Meal Time

Portion size and the intake of others have been found to influence people's food intake. No study, however, has tested the potential influences of both types of situational norms on intake during the same eating occasion. We experimentally tested the effects of manipulating portion size and the intake of others on young women's meal intake during a 20 min eating opportunity. An experimental design with a three (confederate's intake: small, standard, large) by two (portion size: small, standard) between-participants design was used. A total of eighty-five young women participated. Portion size and the confederate's intake both influenced young women's intake. Participants consumed more when offered a larger portion than when offered a smaller portion, and they also ate more when their eating companion ate more. The present results indicate that the effects of portion size and the intake of others were independent but additive. Thus, both types of situational norms might independently guide an individual's intake during a single eating occasion.

Normal Food

Portion sizes of commercially available foods have increased, and there is evidence that exposure to portion sizes recalibrates what is perceived as ‘normal’ and subsequently, how much food is selected and consumed. The present study aims to explore the role of social (descriptive and injunctive) and personal portion size norms in this effect. Across two experiments, participants were either visually exposed to (Study 1, N = 329) or actually served (Study 2, N = 132) a smaller or larger than normal food portion. After 24 h, participants reported their intended consumption (Study 1) or served themselves and consumed (Study 2) a portion of that food and reported perceived portion size norms. In Study 1, visual exposure to portion size did not significantly affect intended consumption and perceived portion size norms. In Study 2, participants consumed a smaller portion of food when they were served a smaller rather than a larger portion the previous day, which was mediated by perceived descriptive and injunctive social (but not personal) portion size norms. Results suggest that being served (but not mere visual exposure to) smaller (relative to larger) portions changes perceived social norms about portion size and this may reduce future consumption of that food.

AbstractObjectiveTo evaluate the validity of food photographs used to support the reporting of food intake with an FFQ designed for adolescents from Rio de Janeiro, Brazil.DesignA set of ninety-five food photographs was elaborated. The photographs’ evaluation process included the acknowledgement of foods and portions in the pictures. In the identification of foods (ninety-five photographs) and typical portions (twelve photographs), the adolescents were requested to answer a structured questionnaire related to the food photographs. The identification of the portion size of amorphous foods (forty-three photographs) was performed using three different portion sizes of actual preparations. The proportions (and 95 % confidence intervals) of adolescents who correctly identified foods and portion size in each photograph were estimated.SettingA public school in Niterói, Rio de Janeiro State, Brazil.SubjectsSixty-two adolescents between 11·0 and 18·9 years old, randomly selected.ResultsAt least 90 % of adolescents correctly identified the food in ninety-two photographs and the food in the three remaining photographs was recognized by 80–89 % of the adolescents. At least 98 % of the adolescents correctly identified eleven typical or natural portions in the food photographs. For amorphous foods, at least 70 % of teenagers correctly identified the portion size in the photograph of thirty-one foods; for the other photographs, the portion size was correctly recognized by 50–69 % of the adolescents for eight foods and by less than 50 % of adolescents for four foods.ConclusionsThe analysed photographs are appropriate visual aids to the reporting of food consumption by adolescents.

Function Mapping

AbstractWhile it has been shown that languages can select quite different formal resources for performing similar pragmatic functions in social interaction, our focus in this paper is the possibility that some types of form-function mapping are essentially universal. Our case study looks at how polar questions are confirmed. For confirming a polar question like ‘Have they gone?’, all languages provide two basic alternatives: an interjection type strategy (something like ‘Yes’) and a repetition type strategy (something like ‘They have gone’). Combinations of these are also possible. Does selection of one of these options have a definable pragmatic function? An analysis of cases from English telephone calls shows that interjection type confirmations are used when the confirmation is relatively straightforward in interactional terms, and where the epistemic terms of the question are accepted by the person who is confirming. By contrast, repetition type confirmations are associated with pragmatic functions where the answerer is in some way resisting the epistemic terms of the question, or dealing with a perturbation of the interactional sequence. We argue that the inherent semiotics of the two strategies explain why they have this distribution; i.e., we do not expect that interjection forms would be standardly used for non-straightforward confirmations, etc. In other words, the form-function mapping observed in English is a non-arbitrary one. Given that this semiotic motivation for choosing one over the other alternative for confirming polar questions should be present in other languages as well, we predict that the mapping observed in English will be observed in other languages as well.
