The peak of health: The vertical representation of healthy food.

As expressed by the "Healthy is Up" metaphor, conceptual metaphor theory argues that the representation of health is commonly associated with high verticality because, typically, people stay upright when they are healthy whereas illness may force them to lie down. Along this line of argument, this research is the first to empirically explore the metaphorical representation of healthy food in terms of verticality. Across five experiments (N = 714), this article first demonstrates that people are faster to pair healthy food with up than down in an implicit association test (Study 1, supporting a metaphorical congruency effect). Then, it shows that people associate healthy food with high verticality and unhealthy food with low verticality by placing healthy food up high and unhealthy food low down along the vertical axis, and by preferring a food pyramid that depicts healthy food at the top rather than at the bottom (Studies 2a, 2b and 3, supporting an abstract-to-concrete effect). Last, this research finds that people judge a food product as healthier when it is pictured from an upward-looking angle than when it is pictured from a downward-looking angle (Study 4, supporting a concrete-to-abstract effect). Further analyses test the interaction between individual differences in self-control and the effects of the "Healthy is Up" metaphor in Studies 2a, 2b, 3 and 4. The article concludes with a discussion of the theoretical and practical implications of this research.

"Animals are friends, not food": Anthropomorphism leads to less favorable attitudes toward meat consumption by inducing feelings of anticipatory guilt.

Why do people befriend animals, yet don't feel conflicted about eating some of them? Previous research on the "meat paradox" suggests that the dehumanization of meat animals plays a crucial role in attenuating the negative affective states that consumers may experience when consuming meat. However, relatively little is known about how the converse process, namely anthropomorphism, influences meat consumption. The current research provides evidence that anthropomorphizing meat animals through the friendship metaphor, "animals are friends", can alter (omnivorous) consumers' attitudes and behavioral intentions toward meat eating, and induce feelings of guilt. More specifically, our experimental findings reveal that anthropomorphism has a negative effect on consumers' attitudes toward the food served in a restaurant and their intentions to patronize it when (pork) meat is on offer. This effect holds whether consumers are invited to consider themselves (Study 1a) or staff members (Study 1b) as taking part in a friendly human-animal interaction. We also demonstrate a similar effect of anthropomorphism on attitudes toward a (pork) meat product and their intentions to buy it, when consumers consider animal-animal friendship or human-animal friendship (Study 2). Last, we show that the negative effect of anthropomorphism on consumers' attitudes and behavioral intentions toward (pork) meat consumption is mediated by increased feelings of anticipatory guilt (Studies 3a and 3c). Nevertheless, no such effect was found with another kind of meat (beef), which indicates that anthropomorphizing meat animals through the friendship metaphor cannot be successfully applied to all commonly eaten species (Study 3b). Implications of these results for meat consumption are discussed.

Taste at first (person) sight: Visual perspective modulates brain activity implicitly associated with viewing unhealthy but not healthy foods.

Every day, people are exposed to images of appetizing foods that can lead to high-calorie intake and contribute to overweight and obesity. Research has documented that manipulating the visual perspective from which eating is viewed helps resist temptation by altering the appraisal of unhealthy foods. However, the neural basis of this effect has not yet been examined using neuroimaging methods. Moreover, it is not known whether the benefits of this strategy can be observed when people, especially overweight, are not explicitly asked to imagine themselves eating. Last, it remains to be investigated if visual perspective could be used to promote healthy foods. The present work manipulated camera angles and tested whether visual perspective modulates activity in brain regions associated with taste and reward processing while participants watch videos featuring a hand grasping (unhealthy or healthy) foods from a plate during functional magnetic resonance imagining (fMRI). The plate was filmed from the perspective of the participant (first-person perspective; 1PP), or from a frontal view as if watching someone else eating (third-person perspective; 3PP). Our findings reveal that merely viewing unhealthy food cues from a 1PP (vs. 3PP) increases activity in brain regions that underlie representations of rewarding (appetitive) experiences (amygdala) and food intake (superior parietal gyrus). Additionally, our results show that ventral striatal activity is positively correlated with body mass index (BMI) during exposure to unhealthy foods from a 1PP (vs. 3PP). These findings suggest that unhealthy foods should be promoted through third-person (video) images to weaken the reward associated with their simulated consumption, especially amongst overweight people. It appears however that, as such, manipulating visual perspective fails to enhance the perception of healthy foods. Their promotion thus requires complementary solutions.

Measuring the transformative utopian impulse for planetary health in the age of the Anthropocene: a multi-study scale development and validation.

BACKGROUND: Transformative utopian impulse for planetary health is people's propensity to have thoughts and engage in actions of which the purpose is to transform the current society into a better one in the future by addressing existing global issues. We aimed to develop a well-validated scale that can measure the transformative utopian impulse for planetary health and uncover its role in societal transformation. METHODS: We developed a scale to measure the transformative utopian impulse for planetary health across 11 studies with 6248 participants from the USA (from the MTurk database) and the UK (from the Prolifico.co database). Participants were eligible take part in the studies if they completed the consent form. Participants who did not pass the seriousness check or did not accurately answer all instructed response items were excluded from statistical analyses. We used exploratory factor analyses (EFA) and confirmatory factor analyses (CFA) to determine the factor structure of the Transformative Utopian Impulse for Planetary Health Scale (TUIPHS). Then we analysed the TUIPHS' nomological network (ie, the relationships between TUIPHS and various constructs ranging from personality traits and values to economic, social, and political attitudes and beliefs). We then examined the scale's incremental predictive validity by testing whether it predicts various attitudes and behaviours relevant to social change beyond scales that measure competing constructs (this part of the study is registered at OSF Registries [https://osf.io/ztj2f]). Finally, we examined the TUIPHS' longitudinal predictive validity by probing whether it predicts people's future support for social change. FINDINGS: Data were collected between Oct 8, 2018, and July 6, 2020. We established that TUIPHS has a four-factor structure and can also be scored as a single general factor, indicating that it captures an overarching theoretical construct (ie, the transformative utopian impulse for planetary health). We then showed that the scale is related to various specific individual difference measures that capture diverse aspects of people's propensity to actively engage in thoughts and actions oriented toward the betterment of society. Moreover, TUIPHS predicted, above and beyond 20 competing scales highly correlated (r ≥0·50) with it, a series of 19 self-reported behavioural and attitudinal constructs pertaining to social change. Finally, participants' past TUIPHS scores predicted their support, a few months later, for social movements that aim to build a more just and resilient society than in the current day. INTERPRETATION: This research lays the groundwork for future theoretical and empirical research into the psychological and behavioural processes attached to the transformative utopian impulse for planetary health as a source of transformative social change toward a better way of being and living.

[Food behaviour and obesity: insights from decision neuroscience]. / Apport des « neurosciences de la décision ¼ à l'étude des comportements alimentaires et de l'obésité - Imagerie et cognition (10).

Neuroimaging allows to estimate brain activity when individuals are doing something. The location and intensity of this estimated activity provides information on the dynamics and processes that guide choice behaviour and associated actions that should be considered a complement to behavioural studies. Decision neuroscience therefore sheds new light on whether the brain evaluates and compares alternatives when decisions are made, or if other processes are at stake. This work helped to demonstrate that the situations faced by individuals (risky, uncertain, delayed in time) do not all have the same (behavioural) complexity, and are not underlined by activity in the cerebral networks. Taking into account brain dynamics of people (suffering from obesity or not) when making food consumption decisions might allow for improved strategies in public health prevention, far from the rational choice theory promoted by neoclassical economics.

Precious Property or Magnificent Money? How Money Salience but Not Temperature Priming Affects First-Offer Anchors in Economic Transactions.

The present study aims for a better understanding of how individuals' behavior in monetary price negotiations differs from their behavior in bartering situations. Two contrasting hypotheses were derived from endowment theory and current negotiation research to examine whether negotiators are more susceptible to anchoring in price negotiations versus in bartering transactions. In addition, past research found that cues of coldness enhance cognitive control and reduce anchoring effects. We attempted to replicate these coldness findings for price anchors in a distributive negotiations scenario and to illuminate the potential interplay of coldness priming with a price versus bartering manipulation. Participants (N = 219) were recruited for a 2 × 2 between-subjects negotiation experiment manipulating (1) monetary focus and (2) temperature priming. Our data show a higher anchoring susceptibility in price negotiations than in bartering transactions. Despite a successful priming manipulation check, coldness priming did not affect participants' anchoring susceptibility (nor interact with the price/bartering manipulation). Our findings improve our theoretical understanding of how the focus on negotiation resources frames economic transactions as either unidirectional or bidirectional, and how this focus shapes parties' susceptibility to the anchoring bias and negotiation behavior. Implications for theory and practice are discussed.

Assessing the Role of Shape and Label in the Misleading Packaging of Food Imitating Products: From Empirical Evidence to Policy Recommendation.

Food imitating products are chemical consumer items used frequently in the household for cleaning and personal hygiene (e.g., bleach, soap, and shampoo), which resemble food products. Their containers replicate elements of food package design such as possessing a shape close in style to drinking product containers or bearing labels that depict colorful fruits. In marketing, these incongruent forms are designed to increase the appeal of functional products, leading to chemical consumer product embellishment. However, due to the resulting visual ambiguity, food imitating products may expose consumers to the risk of being poisoned from ingestion. Thus, from a public health perspective, food imitating products are considered dangerous chemical products that should not be sold, and may merit being recalled for the safety of consumers. To help policymakers address the hazardous presence of food imitating products, the purpose of this article is to identify the specific design features that generate most ambiguity for the consumer, and therefore increase the likelihood of confusion with foodstuffs. Among the visual elements of food packaging, the two most important features (shape and label) are manipulated in a series of three lab studies combining six Implicit Association Tests (IATs) and two explicit measures on products' drinkability and safety. IATs were administered to assess consumers' implicit association of liquid products with tastiness in a within-subject design in which the participants (N = 122) were presented with two kinds of food imitating products with a drink shape or drink label compared with drinks (experiential products with congruent form) and classic chemical products (hygiene products) (functional products with congruent form). Results show that chemical consumer products with incongruent drink shapes (but not drink labels) as an element of food package design are both implicitly associated with tastiness and explicitly judged as safe and drinkable. These results require confirmation in other studies involving different shapes and labels. Notwithstanding, due to the misleading effect of this ambiguity, public health authorities are thus well advised to focus their market surveillance on chemical products emulating a food or drink shape.

Why people drink shampoo? Food Imitating Products are fooling brains and endangering consumers for marketing purposes.

A Food Imitating Product (FIP) is a household cleaner or a personal care product that exhibits food attributes in order to enrich consumption experience. As revealed by many cases worldwide, such a marketing strategy led to unintentional self-poisonings and deaths. FIPs therefore constitute a very serious health and public policy issue. To understand why FIPs are a threat, we first conducted a qualitative analysis on real-life cases of household cleaners and personal care products-related phone calls at a poison control center followed by a behavioral experiment. Unintentional self-poisoning in the home following the accidental ingestion of a hygiene product by a healthy adult is very likely to result from these products being packaged like foodstuffs. Our hypothesis is that FIPs are non-verbal food metaphors that could fool the brain of consumers. We therefore conducted a subsequent functional neuroimaging (fMRI) experiment that revealed how visual processing of FIPs leads to cortical taste inferences. Considered in the grounded cognition perspective, the results of our studies reveal that healthy adults can unintentionally categorize a personal care product as something edible when a food-like package is employed to market nonedible and/or dangerous products. Our methodology combining field (qualitative) and laboratory (behavioral and functional neuroimaging) findings could be of particular relevance for policy makers, as it can help screening products prior to their market release--e.g. the way they are packaged and how they can potentially confuse the mind of consumers--and therefore save lives.

Embodied economics: how bodily information shapes the social coordination dynamics of decision-making.

To date, experiments in economics are restricted to situations in which individuals are not influenced by the physical presence of other people. In such contexts, interactions remain at an abstract level, agents guessing what another person is thinking or is about to decide based on money exchange. Physical presence and bodily signals are therefore left out of the picture. However, in real life, social interactions (involving economic decisions or not) are not solely determined by a person's inference about someone else's state-of-mind. In this essay, we argue for embodied economics: an approach to neuroeconomics that takes into account how information provided by the entire body and its coordination dynamics influences the way we make economic decisions. Considering the role of embodiment in economics--movements, posture, sensitivity to mimicry and every kind of information the body conveys--makes sense. This is what we claim in this essay which, to some extent, constitutes a plea to consider bodily interactions between agents in social (neuro)economics.
