“…Features such as the perceived variety of a food assortment (Kahn and Wansink 2004), and the size of plates, serving bowls, and/or utensils can all impact the quantity that will be consumed. For example, overweight teens consume less juice when pouring into a tall, thin glass relative to a short, wide glass, despite having estimated pouring more (Wansink and Van Ittersum 2003). Perceptual research can also be helpful in promoting a healthy diet.…”

All in the Family? Parental Roles in the Epidemic of Childhood Obesity

Childhood obesity is a serious global health challenge. Families and consumption are at the nexus of the problem, as childhood weight issues depend significantly on family-related influences (genetic predispositions, physical activities, and household food consumption practices). This article focuses on how a family socializes a child toward or away from obesity. It advances a family consumer socialization framework to characterize key elements and processes.Biological predispositions, parent/family inputs, elements of child development, parent-child interactions, and intergenerational transfer are all major contributors to weight status and life course potentials. Time is also a crucial component, here represented in two forms --linear and cyclical. Drawing on extensive research from other disciplines and related consumer research, five "Foundational Properties" are distilled, representing fundamental tenets underpinning the family's role in this problem. Each property is then used to chart promising opportunities for consumer researchers and others interested in advancing knowledge on this pressing concern.

“…Given this difficulty in interpreting percentages, consumers may be more susceptible to influences of a coloured area on pack. In another stream of research, consumer perceptions have been shown to depend on the spatial dimensionality of product packages (Chandon and Ordabayeva 2009;Wansink and van Ittersum 2003). That is, consumers perceive tall and narrow containers differently from short and wide containers, even when objectively their volume is the same.…”

The use of psychological findings in EU internal market regulation has gained interest, particularly in the area of unfair commercial practices. This study investigates consumer perceptions of bonus packs containing an oversized indication of the Bextra^volume in the package, such as in the Mars case. The Mars case serves as a standard reference in EU unfair commercial practices law which is used as a benchmark to determine the Baverage consumer.^Our study demonstrates how an experiment can be set up to provide empirically based insights on whether a practice is Bdeceptive.^Results of our experiment show that consumers overestimate the extra volume when confronted with an oversized indication compared to control conditions, which is first empirical evidence that this practice is potentially deceptive.

“…For example, in two studies, both adults and children underestimated the amount of liquid in short and wide glasses (24,25). In addition, people cannot accurately estimate the calories in various food items and underestimate calories depending on the context in which the foods are presented (26).…”

Neurophysiological Pathways to Obesity: Below Awareness and Beyond Individual Control

A global obesity epidemic is occurring simultaneously with ongoing increases in the availability and salience of food in the environment. Obesity is increasing across all socioeconomic groups and educational levels and occurs even among individuals with the highest levels of education and expertise in nutrition and related fields. Given these circumstances, it is plausible that excessive food consumption occurs in ways that defy personal insight or are below individual awareness. The current food environment stimulates automatic reflexive responses that enhance the desire to eat and increase caloric intake, making it exceedingly difficult for individuals to resist, especially because they may not be aware of these influences. This article identifies 10 neurophysiological pathways that can lead people to make food choices subconsciously or, in some cases, automatically. These pathways include reflexive and uncontrollable neurohormonal responses to food images, cues, and smells; mirror neurons that cause people to imitate the eating behavior of others without awareness; and limited cognitive capacity to make informed decisions about food. Given that people have limited ability to shape the food environment individually and no ability to control automatic responses to food-related cues that are unconsciously perceived, it is incumbent upon society as a whole to regulate the food environment, including the number and types of food-related cues, portion sizes, food availability, and food advertising. Diabetes 57:1768-1773, 2008 T here is a growing consensus that the global obesity epidemic is the result of increasing urbanization and globalization, coupled with significant changes in the food environment (1,2). Obesity was initially highest in developed countries, but developing countries are quickly catching up (3). The dominant thinking about obesity is that prevention and treatment is a matter of self-control and individuals making wiser food choices. However, if this is really the case, then it implies that 30 years ago, before obesity increased, the population had more self-control and made wiser choices, and since then, our collective capacity for selfcontrol must have diminished. It also suggests that people who live in other countries with lower rates of obesity have more self-control than Americans.Just as the suppositions that a change in genetics and/or metabolism is responsible for the increase in obesity over the past three decades are implausible due to lack of evidence of mutations over this short period of time, the idea that the levels of personal responsibility, knowledge, intelligence, or moral character of a majority of the population are rapidly declining is also not a credible explanation of this phenomenon. It is unlikely that the nature of people has changed so dramatically. What has changed dramatically, however, is the environment in which we now live.The availability and affordability of food has increased, due to a combination of technological advances in food preservation and packaging, i...
