Unperceived, the impact of information gap design plateware on food waste.

Curiosity is a powerful motivator of behaviour. Although there have been some studies pertaining to the application of curiosity in the realm of food, research examining the potential to influence consumer food waste behaviour through the induction of curiosity is lacking. This study conducted two onsite dining experiments to explore the role and mechanism of curiosity in reducing food waste in a real dining environment by utilising an information gap design in tableware to induce participants' curiosity. Experiment 1 investigated the differences in food waste between participants using bowls with an information gap design and those using bowls with no information gap (blank bowls). Experiment 2 further controlled for other variables that could potentially influence the outcomes between bowls with and without information gaps; the latter displayed complete text externally. The results of both experiments consistently demonstrated a significant reduction in participants' food waste when utilising utensils with an information gap design. Moreover, we conducted an exploratory analysis combining these two experiments to examine the mediating mechanisms involved. Furthermore, the exploratory analysis suggested the mediating mechanism of curiosity elicited by the information gap design, ultimately leading to a decrease in food waste. This study presents a potential avenue for a simple and innovative approach for mitigating food waste.

Stat5a promotes Col10a1 gene expression during chondrocyte hypertrophic differentiation.

OBJECTIVES: Multiple transcription factors (TFs) have previously been shown to control hypertrophic chondrocyte-specific mouse type X collagen gene (Col10a1) expression via interaction with Col10a1 promoters. This study aims to investigate the role and mechanism of the potential binding factor signal transduction and transcription activator 5a (Stat5a) of Col10a1 cis-enhancer, in controlling Col10a1 gene expression and chondrocyte hypertrophic differentiation. METHODS: The potential Col10a1 regulator was predicted by the transcription factor affinity prediction (TRAP) analysis of the 150-bp Col10a1 cis enhancer. Stat5a was screened and verified by qRT-PCR, western blot and IHC analyses. Transfection of Stat5a siRNA or expression plasmid into MCT and ATDC5 cells was performed to either knockdown or over-express Stat5a and to investigate the influence of Stat5a on Col10a1 gene expression during the chondrocyte hypertrophy. Dual-luciferase reporter assay was performed to explore the mechanism of Stat5a affecting Col10a1 transcription. Alcian blue, alkaline phosphatase, and alizarin red staining, as well as qRT-PCR analyses of related marker genes were performed to investigate the effect and possible mechanism of Stat5a on chondrocyte differentiation. RESULTS: The potential binding factor of Col10a1 cis-enhancer Stat5a and Col10a1 were both highly expressed and positively correlated within hypertrophic chondrocytes in vitro and in situ. Knockdown of Stat5a reduced Col10a1 expression, while overexpression of Stat5a enhanced Col10a1 expression in hypertrophic chondrocytes, suggesting Stat5a as a positive Col10a1 regulator. Mechanistically, Stat5a was shown to potentiate the reporter activity mediated by Col10a1 promoter/enhancer. In addition, Stat5a increased the intensity of alkaline phosphatase staining of ATDC5 cells and the expression of relevant hypertrophic marker genes including Runx2, which was consistent with the expression of Stat5a and Col10a1. CONCLUSIONS: Our results support that Stat5a promoted Col10a1 expression and chondrocyte hypertrophic differentiation, possibly via interaction with the 150-bp Col10a1 cis-enhancer.

The Voice of Morality: The Two-Way Relationship Between the Beauty of Voice and Moral Goodness.

BACKGROUND: Morality is a point of great concern to us in our social interactions. We also assess people's morality based on a variety of external factors. Research has found that the beauty of faces can influence people's moral assessments, and that moral assessments can in turn influence our judgments about the beauty of faces. In real life, the voice is a very important communication mediu. People can gain knowledge of individuals through their voices. However, the relationship between voice beauty and moral goodness has never been investigated. OBJECTIVES: So, the present study investigated the two-way relationship between voice beauty and moral goodness traits during impression formation. METHOD: We collected empirical data from 32 college students in China followed the impression formation paradigm in Experiment 1 and collected empirical data from 32 college students in China followed moral priming paradigm. RESULTS: The results of Experiment 1 showed that high attractive voices were more likely to be judged to have higher moral goodness levels. Conversely, the results of Experiment 2 showed that the moral priming condition revealed a higher score for the voice than the immoral condition. The results showed that the bidirectional validation of voice beauty-moral goodness was significant, that is, participants tend to rate high attractive voices with higher moral goodness levels, and rate moral people's voices with higher beauty. CONCLUSION: Based on these results, we found a two-way relationship between the beauty of voice and morality, and once again demonstrated the role of voice in message transmission.

Ugly food, not eat: the eating intention of emotional eater for different esthetic food.

BACKGROUND: Emotional eaters eat to relieve their emotions. However, food also contains esthetic information. People generally perceive ugly food as unhealthy and unpalatable. Does the esthetic information of food influence an emotional eater's desire for food in a negative emotional state? In particular, do they have the same lower eating intentions for low esthetic food as non-emotional eaters? OBJECTIVE/DESIGN/MEASURES: Based on these questions, the present study examined whether the esthetic value of food influences emotional eaters' desires for food. The experiment used a 2 (eating type: emotional eating vs. non-emotional eating) × 2 (food style: high esthetic vs. low esthetic) mixed experimental design. We measured the emotional and non-emotional eaters' eating intentions for different esthetic foods when experiencing negative emotions. RESULTS: The results showed that emotional eaters have higher intention to eat high esthetic foods. However, they did not have a high eating intention for all foods, and their eating intention did not differ from that of non-emotional eaters when faced with low esthetic food. CONCLUSION: In conclusion, food esthetic value can affect individual eating intentions. Even for emotional eaters who are in a negative mood, they also did not have a higher eating intention for low esthetic food compared with no-emotional eater. LEVEL OF EVIDENCE: Level II: controlled trial without randomization.

Solid or Liquid Food-The Intention to Eat Different Foods under Negative Emotions.

Food can relieve an individual's emotions, especially for emotional eaters. For instance, chewing alleviates negative emotions. Solid and liquid foods comprise a huge part of our daily lives, and the chewiness of solid foods is always high. Here, we explored whether people, especially emotional eaters, have higher eating intentions to eat highly chewy foods while experiencing negative emotions by comparing their eating intentions toward solid and liquid foods. To this end, we conducted a survey of 147 participants using a questionnaire (Experiment 1) to understand their eating intention toward five types of food (purple potato, maize, black soya bean, mango, and soybean; each food group contained a solid food and a liquid food) while experiencing negative emotions. The results showed that individuals exhibited higher eating intention toward solid food compared with liquid food while experiencing negative emotions. In Experiment 2, we selected 85 and 65 high-emotional and low-emotional eaters, respectively, and further explored their preference for solid foods. The results showed that individuals with high levels of emotional eating exhibited higher intentions toward solid food while experiencing negative emotions compared with those with low levels of emotional eating. In conclusion, this study proved that individuals' higher eating intentions toward highly chewable food were pronounced among individuals with high levels of emotional eating under negative emotion conditions.

Does a beautiful environment make food better - The effect of environmental aesthetics on food perception and eating intention.

Generally, people prefer to dine in beautiful environments. Previous studies have reported that environmental factors affect an individual's perception of food; however, little is known about the effect of environmental aesthetics on food perception. In Experiment 1, we used photographs of restaurant (1a) or non-restaurant (1b) environments with high or low aesthetic value, paired with images of foods, and participants were asked to rate the visual, olfactory, and gustatory aesthetic value of the food. Results showed significantly higher ratings for food perception in all three sensory modalities in the high aesthetic value environment, together with positive emotion and the desire to eat, compared with the low aesthetic environment. Experiment 2 extended the study to two real-world environments (one high and one low aesthetic value) and actual food consumption. The results also found higher aesthetic ratings in the olfactory and gustatory systems and greater desire to eat again in an environment with high aesthetic value than in an environment with low aesthetic value. This research also explored the mediating role of emotion in the relationship between environmental aesthetics and food perception and found a significant mediating relationship. In conclusion, environmental aesthetics play an important role in food perception, and these findings provide insights into increasing positive food perception in daily life.

Tasting More Than Just Food: Effect of Aesthetic Appeal of Plate Patterns on Food Perception.

Interest has been growing in the role of subjective aesthetics in the field of food. This study explored the mechanisms by which the aesthetic appeal of plate patterns influences consumers' perceptions of food. Three experiments were conducted to compare whether different levels of beauty and types of plate pattern aesthetics (classical versus expressive) affected the perceptions of tastiness and healthiness of the food offered. Experiment 1 was carried out with 30 participants, and the results showed that participants perceived the food presented on more beautiful plates as tastier and healthier than the food on less beautiful plates. Experiment 2 was carried out with 128 participants; the results showed that, for expressively aesthetic plates, the participants experienced more positive emotions for very beautiful plates and more negative emotions for less beautiful plates. However, for classical aesthetic plates, participants' emotions were not affected by the beauty of the plate. Experiment 3 was carried out with 149 participants, and the results showed that, for classically aesthetic plates, participants perceived the food placed in the middle to be tastier than food placed at the edge; however, for expressively aesthetic plates, food placement did not affect participants' perceptions of food. These results demonstrate the importance of the subjective beauty of plate patterns in influencing consumers' food perceptions, although this influence varies depending on the type of aesthetic design of the plate pattern.

The impact of action observation and motor imagery on the aesthetic preference of Chinese calligraphy.

The creation of artwork requires motor activity. However, few empirical studies have directly explored the relationship between the experience of an artist's action and aesthetic experience. This study aimed to examine the effect of observing and imagery of the artist's action on the participants' aesthetic preferences. In Experiment 1 and 2, we took hard-pen and brush-pen Chinese calligraphy images as the stimulus, respectively, to explore the influence of action observation on the aesthetic preference by manipulating the artists' actions. The results of both Experiment 1 and 2 show that when participants observed the artists' actions, they tended to report a higher preference for calligraphy images compared with the control condition. In Experiments 3 and 4, we used instructions to manipulate the motor imagery tasks and investigated the effect of imaging the artist's action on the participants' aesthetic preferences. The results showed that both kinesthetic imagery and visual imagery increased the participants' preference. In general, our study shows that both action observation and motor imagery contribute to participants' aesthetic preferences. The results are discussed in terms of how artists' actions possibly influence the aesthetic preference of Chinese calligraphy.

Spacious Environments Make Us Tolerant-The Role of Emotion and Metaphor.

The physical environment plays an important role in moral cognition. Previous research has demonstrated that the physical environment affects individual moral judgment. Investigators have argued that the environment influences moral judgment through emotion and cognition, such as during metaphor processing. Following the intensification of urbanization and increases in population size, the phenomenon of a narrow environment has become more common. However, the relation between environmental spaciousness and moral judgment has not been thoroughly examined. We examined the effect of environmental spaciousness (spaciousness vs. narrowness) on moral judgments in Experiment 1 and Experiment 2. Results showed that participants report a higher rating score of moral judgment in more spacious environments compared with narrow environments. We further explored the roles of emotion and metaphor in the relation between environmental spaciousness and moral judgments. We found support for a partial mediation effect of emotion in the relationship between environmental spaciousness and moral judgment. The results also supported an association between the concept of spaciousness and tolerant cognition. Spacious environments may elicit positive emotions and more tolerant cognition, which in turn influences moral judgment. These results provide new evidence for the influence of the environment on moral judgments, and more attention may be warranted to incorporate this relationship in environmental design.

Environmental Aesthetic Value Influences the Intention for Moral Behavior: Changes in Behavioral Moral Judgment.

The environment affects moral behavior. Previous research found that a beautiful environment leads to pro-social behavior, which is related to behavioral intention. However, the effect of environmental aesthetic value on immoral and moral behavior remains unclear. Therefore, in the present study, we explored the effect of environmental aesthetic value on behavioral intention and its possible mechanisms. We conducted four experiments. Experiment 1 adopted the priming paradigm and IAT paradigm to explore the relationship between environmental aesthetic value and behavioral intention. It used photographs of the environment as priming stimuli and scene drawings of behavior as target stimuli. The results showed that participants had a higher intention to engage in moral behavior in an environment with a high aesthetic value, and a lower intention to engage in immoral behavior, compared to in an environment with a low aesthetic value. Similarly, an environment with a low aesthetic value was related to immoral behavior. Experiment 2 further explored the possible mechanism for the above results: changes in moral judgment. The results showed that moral judgment in different environments may lead to different behavioral intentions. The current study extends prior research by demonstrating the effect of environmental aesthetic value on behavioral intention and moral judgment, and good knowledge about the relationship between environmental aesthetic value and moral behavior. In addition, it provides a new hypothesis for the relationship between environment and behavior according to the results of the environment-behavior matching hypothesis, which can provide a new perspective on moral education.
