Food-related emotional expectancies influence food intake, yet little is known about their determinants. The present study objectives were to experimentally test how food advertisements affect food-related emotional expectancies in adults and whether effects differed by individual levels of “food addiction” symptoms. Participants ( n ?=?718; M_(age) ?=?35.88, 36.8% with food addiction) were randomly assigned to watch video advertisements for highly processed foods, minimally processed foods, both food groups, or cellphones (control). Participants completed an attention check and questionnaires including the Anticipated Effects of Food Scale. Main effects of condition were non-significant. In participants with fewer symptoms of food addiction, watching video advertisements for highly processed foods increased expectancies that one would feel positive emotions while eating those foods, B ( SE )?=?0.40(0.16), p ?=?0.016, 95% CI (0.08, 0.72), ΔR ~(2)?=?0.03. Highly processed food advertisements may affect food-related emotional expectancies in adults who have not previously formed strong expectancies.

Objectives: Individuals often experience expectation violations related to the consumption of healthy food and physical activity and they may cope with expectation-disconfirming information by (1) ignoring the discrepancy (immunization), (2) increasing efforts to fulfill them (assimilation), or (3) changing their expectations (accommodation). We investigated whether valence, discrepancy magnitude, and controllability of the expectation disconfirming event predicted coping with expectation violations. Methods: A 2 (valence: positive vs negative) x 2 (discrepancy: larger vs smaller) x 2 (controllability: control vs no control) experimental design was implemented. Overall, we presented 297 university students with vignettes describing expectation violations and present different combinations of predictor levels. Results: Regarding physical activity, participants showed significantly higher accommodation when experiencing a better-than-expected event and showed significantly higher immunization when experiencing a worse-than-expected event. Regarding food consumption and physical activity, individuals experiencing lower discrepancy showed significantly higher immunization; individuals with control over the source of expectation disconfirmation showed significantly higher assimilation; and individuals without control over the source of expectation disconfirmation showed significantly higher accommodation. Conclusions: To promote the maintenance of healthy expectations, despite expectation violations, interventions could foster the perception of control as well as assimilative behavior.

How enjoyable a food product is remembered to be is likely to shape future choice. The present study tested the influence that expectations and specific moments during consumption experiences have on remembered enjoyment for food products. Sixty-four participants consumed three snack foods (savoury, sweet and savoury-sweet) and rated expected and online enjoyment for each product. Twenty-four hours later participants rated remembered enjoyment and future expected enjoyment for each product. Remembered enjoyment differed to online enjoyment for two of the three products, resulting in the foods being remembered as less enjoyable than they actually were. Both expected enjoyment and specific moments during the consumption experience (e.g. the least enjoyable mouthful) influenced remembered enjoyment. However, the factors that shaped remembered enjoyment were not consistent across the different food products. Remembered enjoyment was also shown to be a better predictor of future expected enjoyment than online enjoyment. Remembered enjoyment is likely to influence choice behaviour and can be discrepant to actual enjoyment. Specific moments during a consumption experience can have disproportionately large influence on remembered enjoyment (whilst others are neglected), but the factors that determine which moments influence remembered enjoyment are unclear.

Edible insects have attracted much Western interest in recent years due to their nutritional and environmental advantages. Consumers, however, remain aversive towards a class of items that is not traditionally considered to be food. While the focus is often on the Western disgust, looking at consumer perceptions in a culture that considers insects to be delicious could provide new insights into the psychological and cultural mechanisms that underpin these evaluations. This cross-cultural qualitative study explores how cultural exposure and individual experience contribute towards the contrasting evaluations of insects as food by those who do and do not eat them. Eight focus groups were conducted across two cultures four in Thailand where insects are part of the local food culture, and four in the Netherlands where insects are generally not recognised as food. Within these cultures, two groups consisted of individuals who have experience with eating insects, and two groups consisted of individuals with little or no experience with insects as food. Cultural exposure created expectations of which species were more appropriate to eat and how they should be prepared, whereas individual experiences determined whether judgements were made based on memories of past eating experiences or based on the visual properties and item associations. This study provides insights into the acceptance and rejection factors of unfamiliar food items and identifies the factors to be considered when introducing novel food items that are not yet culturally acceptable as food.

As greater food variety has been shown to increase intake and is associated with a higher BMI, interventions that modify the effects of food variety have implications for combatting obesity. Previous research has shown that labelling a food with 'high variety' flavour-specific labels can reduce an individual's satiation whilst eating. We were interested in whether the effects of 'variety labelling' would also be observed on portion size selection and ad libitum food intake. Therefore, two studies were conducted to explore the effects of labelling foods with different levels of variety on ideal portion size, ratings of expected fullness, and actual intake. In Study 1 (N = 294), participants viewed images of a range of foods that were presented with either high variety labels (descriptions of within-food components), low variety labels (general names of food items), or no label in an online survey. They selected their ideal portion size and rated their expected fullness for each food. In Study 2 (N = 99), they also consumed one of these foods ad libitum in the laboratory. It was hypothesised that foods presented with high variety labels would have an increased ideal portion size, reduced expected fullness, and increased intake compared to foods presented with low variety labels or no label. Our findings failed to support these predictions, and we found no evidence of an effect of variety labelling on ideal portion size, expected fullness or food intake. These findings highlight the importance of considering the ecological validity of consumer research studies.

Expectancy theory has been widely applied in substance use research but has received less attention in eating behavior research. Measuring food expectancies, or the anticipated outcomes of eating specific foods, holds theoretical and practical promise for investigations into nonhomeostatic eating behavior. The current study developed and assessed the psychometric properties of a novel measure of positively and negatively valenced highly (e.g., sweets, salty snacks, fast foods, sugary drinks) and minimally (e.g., fruits, vegetables) processed food expectancies. The Anticipated Effects of Food Scale (AEFS) was adapted from a self-report of alcohol expectancies, piloted for item generation/retention and readability, and preliminarily validated in an adult sample (N = 247; M-age = 36.84; 53.3% male; 74.5% White). Consistent with the substance expectancies literature, AEFS positive highly processed food expectancies were associated with greater added sugars intake, r =.17, p =.009, and food addiction symptoms, r =.56, p =.001. Of note, AEFS negative minimally processed food expectancies were robustly associated with food addiction symptoms, r =.81, p =.001, and, together with AEFS positive highly processed food expectancies, explained 67% of the variance in food addiction symptoms. Furthermore, AEFS food expectancies demonstrated incremental validity with food addiction symptoms above and beyond general eating expectancies. The AEFS seems to be a psychometrically sound measure and can be used to investigate cognitive-affective mechanisms implicated in highly processed food intake and food addiction. Moreover, the present results provide new insight into potential food expectancy challenge intervention approaches for preventing nonhomeostatic eating behavior.

The "babyboomer" generation, those who were born between 1946 and 1965, account for over 30% of the population in Australia, and it is no surprise that the government is concerned about the financial implications for future healthcare costs. While many babyboomers are more financially secure than previous generations have been on account of compulsory superannuation contributions made over the past 15 years, there are still some who are financially vulnerable and expect to rely on government pensions and welfare assistance. Changes to family structures and job security also mean that those who are less financially secure will need social support. Using an ecological framework model, we explored the retirement expectations and experiences of some Australian babyboomers through focus groups and individual interviews to identify key issues and their plans to address these issues. Four main themes are reported in this paper: retirement attitudes and expectations, finances, health, and food. The results suggested that for many persons retirement equated freedom. Little future planning was undertaken for retirement other than contributing to superannuation schemes, and expectations were reported in general terms, such as wanting to remain independent and healthy and to have time to socialize and travel.
