Title Restricting access to foods and children's eating Type Journal Article
Year 1999 Publication Appetite Abbreviated Journal Appetite
Volume 32 Issue 3 Pages 405-419
Keywords Child Behavior/*psychology; Child, Preschool; Feeding Behavior/*psychology; Female; Food Preferences; Humans; Male; *Mother-Child Relations; Nutritional Requirements; Obesity/psychology; Sex Factors
Abstract This study evaluated maternal restriction of children's access to snack foods as a predictor of children's intake of those foods when they were made freely available. In addition, child and parent eating-related “risk” factors were used to predict maternal reports of restricting access. Participants were 71, 3-to-5-year-old children (36 boys, 35 girls) and their parents. Children's snack food intake was measured immediately following a meal, in a setting offering free access to palatable snack foods. Child and maternal reports of restricting children's access to those snack foods were obtained. In addition, information on child and parent adiposity as well as parents' restrained and disinhibited eating was used to examine “risk” factors for restricting access. For girls only, child and maternal reports of restricting access predicted girls' snack food intake, with higher levels of restriction predicting higher levels of snack food intake. Maternal restriction, in turn, was predicted by children's adiposity. Additionally, parents' own restrained eating style predicted maternal restriction of girls' access to snack foods.

Title Slave to habit? Obesity is associated with decreased behavioural sensitivity to reward devaluation Type Journal Article
Year 2015 Publication Appetite Abbreviated Journal Appetite
Volume 87 Issue Pages 175-183
Keywords Adaptation, Physiological; Adult; Body Mass Index; Body Weight; Energy Intake; Feeding Behavior/*psychology; Health Behavior; Humans; Hunger; Hyperphagia/psychology; Linear Models; Male; Models, Biological; Motivation; Obesity/*psychology; *Reward; Satiation; Surveys and Questionnaires; Young Adult; Control of food intake; Devaluation; Goal-directed; Habitual; Obesity; Reward sensitivity
Abstract The motivational value of food is lower during satiety compared to fasting. Dynamic changes in motivational value promote food seeking or meal cessation. In obesity this mechanism might be compromised since obese subjects ingest energy beyond homeostatic needs. Thus, lower adaptation of eating behaviour with respect to changes in motivational value might cause food overconsumption in obesity. To test this hypothesis, we implemented a selective satiation procedure to investigate the relationship between obesity and the size of the behavioural devaluation effect in humans. Lean to obese men (mean age 25.9, range 19-30 years; mean BMI 29.1, range 19.2-45.1 kg/m(2)) were trained on a free operant paradigm and learned to associate cues with the possibility to win different food rewards by pressing a button. After the initial training phase, one of the rewards was devalued by consumption. Response rates for and wanting of the different rewards were measured pre and post devaluation. Behavioural sensitivity to reward devaluation, measured as the magnitude of difference between pre and post responses, was regressed against BMI. Results indicate that (1) higher BMI compared to lower BMI in men led to an attenuated behavioural adjustment to reward devaluation, and (2) the decrease in motivational value was associated with the decrease in response rate between pre and post. Change in explicitly reported motivational value, however, was not affected by BMI. Thus, we conclude that high BMI in men is associated with lower behavioural adaptation with respect to changes in motivational value of food, possibly resulting in automatic overeating patterns that are hard to control in daily life.

Title Influence of environmental factors on meal intake in overweight and normal-weight male adolescents. A laboratory study Type Journal Article
Year 2012 Publication Appetite Abbreviated Journal Appetite
Volume 59 Issue 1 Pages 90-95
Keywords Adolescent; *Energy Intake; *Environment; Feeding Behavior/*psychology; France; Humans; Hunger/physiology; Male; Music; *Overweight; Television; Thirst/physiology
Abstract OBJECTIVE: To investigate the influence of environmental conditions on energy intake at lunch time in normal-weight versus overweight male adolescents. DESIGN: Healthy 15-17 year-old adolescents (19 normal-weight, 19 overweight) participated in lunch tests under laboratory settings. Four conditions were compared: eating in groups, eating alone, eating alone while viewing television, eating alone while listening to music. The same menus (two solid foods, three drinks) were offered ad libitum. RESULTS: Significant group differences between meal conditions were observed for energy intake from solid foods, but not from drinks: normal-weight participants ate more solids while listening to music (5731+/-426 kJ) than when eating alone (5012+/-364 kJ, P=0.026) or in groups (4974+/-272 kJ, P=0.049), whereas overweight participants ate more solid foods while viewing television (5806+/-330 kJ) than when eating in groups (5208+/-201 kJ, P=0.014) or while listening to music (5288+/-255 kJ, P=0.035). On average, total energy intake at lunch (solids plus liquids) was found to be increased only in the overweight when viewing television (8527+/-535 kJ) compared to eating in group (7348+/-445 kJ, P=0.037) or while listening to music (7532+/-435 kJ, P=0.049). CONCLUSION: Environmental conditions modulate total energy intake at lunch in adolescents and susceptibility to external factors can be affected by weight status. Whether such effects can in turn affect energy balance and weight status remains to be investigated.

Title Parental child feeding practices: how do perceptions of mother, father, sibling, and self vary? Type Journal Article
Year 2014 Publication Appetite Abbreviated Journal Appetite
Volume 80 Issue Pages 96-102
Keywords Body Mass Index; Child; Fathers; Feeding Behavior/*psychology; Female; Humans; Male; Mothers; *Parent-Child Relations; Siblings; Socioeconomic Factors; Surveys and Questionnaires; Child feeding practices; Eating behavior; Family systems; Parent-child interactions
Abstract Mothers are important contributors to the development of eating behavior in children, but less is known about the influence of fathers. The purpose of this study was to investigate family perceptions of parental child feeding practices. Seventy two-parent American families including a mother, father, and two biologically related children participated in the study. Participants completed parent and child versions of the Child Feeding Questionnaire that assessed perceptions of parental control in child feeding. Most family member reports were positively correlated, indicating agreement about the use of the examined parental feeding practices; however, some salient differences between the reported behaviors of mothers and fathers were uncovered. Mothers reported using higher levels of monitoring and responsibility than fathers. In addition, fathers and children reported higher levels of paternal pressure related to feeding compared with mothers. Mothers and fathers used more pressure and felt more responsible for feeding younger children compared with older children. One interaction revealed that older male siblings reported the highest level of pressure from fathers. Reported differences in parents' use of child feeding practices suggest that mothers and fathers may have distinct interactions with their children regarding food. Paternal feeding practices are likely to have unique implications for understanding the development of children's eating behavior.

Title Social facilitation of eating: effects of social instruction on food intake Type Journal Article
Year 1992 Publication Physiology & Behavior Abbreviated Journal Physiol Behav
Volume 52 Issue 4 Pages 749-754
Keywords Adolescent; Adult; Arousal; Computer Simulation; Dietary Fats/administration & dosage; *Eating; Energy Intake; Feeding Behavior/*psychology; Female; Humans; Male; Middle Aged; Motivation; Nutritive Value; *Reinforcement, Social; *Social Facilitation; Social Isolation; Sodium, Dietary/administration & dosage
Abstract To investigate whether social influences cause increases in eating behavior, thirty undergraduate psychology students completed a diet diary for three 5-day periods. Subjects were instructed to either eat alone or eat with other people, actively eating with them for two of these periods. For the third period, subjects were instructed to eat as they normally would (with or without other people present). When instructed to eat with others present, subjects overall consumed more food, water, sodium, and alcohol than when they were instructed to eat alone. In the normal condition, food intake was 60% higher when the subjects ate with others present than when they ate alone. These results suggest that social facilitation has a causal influence on eating which increases food intake.
