The widespread use of molecular biological tools has led to a pronounced increase in the number of signals that are now implicated in the controls of food intake and body weight. However, a complete understanding of the roles of these multiple signals requires that we assess how they interact with one another to alter ingestive behavior. Although many such experiments are being conducted, the m...

Earlier studies have shown that thwarting of feeding behaviour in the laying hen is expressed through a specific vocalisation, the gakel-call. The first aim of this study was to investigate whether the effect of deprivation per se on the occurrence of gakel-calls can be distinguished from the effect of the additional frustration. Frustration is defined as the state of an animal that results fro...

Food neophobia and picky/fussy eating behavior are presented as the two main forms of children's food rejections which are responsible for a reduction of their dietary repertoire. We review the key factors, presented in the literature, that are involved in food rejections during childhood. We first consider a range of "cognitive factors", such as food perception, mental representations, categor...

This study reports the development and validation of the 20 item Family Food Behavior Survey, a measure designed to assess broad components of the family food environment that may contribute to child overweight. In a diverse sample of 38 parents, factor analyses verified 4 domains: (1) maternal control of child eating behavior; (2) maternal presence during eating; (3) child choice, and (4) orga...

aim and background: poor nutritional behaviors currently are a widespread issue. poor nutritional behaviors include inability to maintain control over eating, food restriction with the purpose of influencing on weight and shape, and tendency toward overeating in response to the negative emotions. this study was conducted to review the relationship between the perceived body satisfaction, perfec...

Poor individuals often engage in behaviors, such as excessive borrowing, that reinforce the conditions of poverty. Some explanations for these behaviors focus on personality traits of the poor. Others emphasize environmental factors such as housing or financial access. We instead consider how certain behaviors stem simply from having less. We suggest that scarcity changes how people allocate at...

This paper summarizes our previous works in modeling non-verbal behaviors for natural human-robot interaction (HRI) and discusses a path for integrating them into spoken dialogs. While some non-verbal behaviors can be considered “optional” elements to be added to a spoken dialog, some non-verbal behaviors substantially require a harmonized plan that simultaneously considers both spoken dialog a...

For developing usable service robots, deeper knowledge about how the robot should cope with many situations is essential. We suggest some behavioral goals for better communication with network based entertainment robots. First, the robot should show diverse behaviors. Second, the diverse behaviors should be coherent with some traits of personality. Finally, the behaviors or responses of the rob...

Most children will engage in sexual behaviors at some time during childhood. These behaviors may be normal but can be confusing and concerning to parents or disruptive or intrusive to others. Knowledge of age-appropriate sexual behaviors that vary with situational and environmental factors can assist the clinician in differentiating normal sexual behaviors from sexual behavior problems. Most si...
