Influence of the glassware on the perception of alcoholic drinks

Two studies are reported in which the effect of glassware was investigated on subjective ratings of, and willingness-to-pay for, alcoholic drinks. Participants from China (Study 1) and the USA (Study 2) viewed online photographs of red wine, white wine, beer, whisky, and Chinese baijiu presented in 6 different glasses, including a narrow, wide, or stemless wine glass, a highball or rocks glass, and a beer mug. They rated liking, familiarity, and congruency (between the drink and the glassware), as well as how much they would be willing to pay for the drinks. Both the type of drink and the type of glassware influenced participants’ subjective ratings of, and willingness-to-pay for, the drinks. The red and white wine were liked more, and people were willing to pay significantly more for if they thought that the glassware was congruent with the contents. These findings highlight the influence of content–context congruency on consumers’ subjective ratings and willingness-to-pay.     

Crossmodal associations and subjective ratings of Asian noodles and the impact of the receptacle

We investigated the crossmodal associations that people hold for Asian noodles, and the influence of the plateware/receptacle. Chinese participants viewed online photographs of natural, red, green, and yellow noodles presented in bowls or plates made from ceramic, glass, paper, or stainless steel. In Experiment 1, the participants reported the first taste/flavour that came to mind, and rated their feelings and taste/flavour expectations concerning the noodles. In Experiment 2, the participants had to choose a taste term from a list to indicate the first taste that came to mind, and rated their feelings about the noodles. The results of both experiments revealed that the red noodles tended to be associated with a spicy taste/flavour; whereas the yellow noodles were often associated with a savoury taste/flavour, and rated as looking more familiar and pleasant than either the red or green noodles. The receptacles used to present the noodles did not influence the observed colour-flavour associations. However, the material of the receptacles appeared to interact with the colour of the noodles in terms of influencing people’s subjective ratings of, and taste/flavour expectations concerning, the noodles. These findings therefore demonstrate the complex interactions that can occur between the colour of the product and the type/material of the receptacle on people’s expectations regarding the taste/flavour of Asian noodles in the Asian marketplace.     

Price information influences the subjective experience of wine: A framed field experiment

Past experimental laboratory and correlational data from observational research has shown that knowledge of the price of wine influences the consumer’s subjective experience. However, there is limited prior research that has explicitly manipulated price information in a realistic wine tasting setting. A total of 140 participants tasted three different low-, mid- and high-priced wines with open, deceptive, or no price information and rated them for taste intensity and pleasantness. In our community sample, intensity of taste ratings for open, deceptive and blind price information reflected retail prices, thus more expensive wines were rated as more intense in taste. However, while pleasantness ratings did not differ for open and no price information, deceptive up-pricing of low-price wine significantly influenced ratings for pleasantness, whereas deceptive down-pricing of high-price wine had no effect on pleasantness ratings. Thus, pricing information differentially influences the consumer’s subjective experience of wine, with no effects on intensity of taste ratings and no effects on pleasantness ratings with correct or no price information, but increased pleasantness of low-price wine when provided with a deceptive higher price. Thus, in wine may lay the truth, but its subjective experience may also lie in the price.     

Cup colour influences consumers’ expectations and experience on tasting specialty coffee

The present study was designed to investigate the effect of the colour of the cup on sensory and hedonic judgments of specialty coffee by consumers. Altogether, 457 participants took part in one of three experiments. Crossmodal correspondences between the colour of the cup (i.e., an extrinsic cue) and the taste profile of the coffee served (i.e., the contents) were manipulated. Congruent and incongruent colour × taste pairings were created by using four cup colours (white, pink, yellow, and green) and two coffee profiles (sweet Brazilian and acidic Kenyan) to assess whether these manipulations would affect pre-and/or post-tasting ratings. Participants first rated their expectations of sweetness and acidity, and subsequently, their experience of those attributes on tasting the coffees, as well as rating their liking. The results revealed that the colour of the cup exerted a significant influence on both pre- and post-tasting ratings for all attributes measured. Liking ratings significantly decreased in incongruent pairing conditions – which also increased the unexpected acidity of the Kenyan coffee when tasted from the pink cup. Taken together, these results demonstrate for the first time that the colour of the cup significantly impacts sensory and hedonic judgements of specialty coffee. Our results also show that the contrast between expected and actual experience can result in a negative hedonic response and the enhancement of the unexpected sensory attribute. Implications for the development of coffee cups that can enhance the drinking experience are highlighted.     

Differential effects of brand,ratings and region on willingness to pay: a hedonic price approach

How consumers respond to signals of a products quality plays an integral role in marketing strategy. While the effects of product characteristics such as brand, region of origin, and ratings have been studied extensively, research on how they interact with each other and the differential effects of these by market segment has not been studied. This paper provides a unique insight into the purchasing behavior of US wine consumers and shows how brand, region and ratings interact and how each has a different effect dependent on price segments and varietal. We attribute these differences to unobserved heterogeneity across consumers who respond differently to different signals of quality. Using data on retail wine purchases in the USA combined with third-party ratings, we used a fixed-effects model to analyze willingness to pay for wine. Our findings provide marketers with a guide to which product characteristics in terms of brand, ratings, and region are the most effective signals of quality to different consumer market segments.     

Assessing the expectations associated with pharmaceutical pill colour and shape

Two experiments are reported in which people’s sensory, hedonic, and efficacy expectations associated with pharmaceutical pills of differing colour and shape were assessed. In Experiment 1, 101 participants from the USA viewed online photos of tablets having one of 7 colours and 3 shapes. The participants had to arrange the 21 tablets based on the expectations generated solely by the tablets’ visual properties. The results revealed that the colour of the tablets influenced expected bitterness, expected alertness, and expected efficiency in combating headaches, whereas the shape of the tablets influenced the expected difficulty of swallowing. In Experiment 2, the major findings of Experiment 1 were replicated while using a greater variety of colours, in 358 participants from China, Colombia, and the USA. Importantly, the results revealed some shared expectations across cultures, such as the high expected efficacy of white tablets in combating headaches, or the high expected difficulty of swallowing the diamond-shaped tablets. The results also revealed some differences among the three groups, such as that the colour of the pills influenced how difficult the Chinese participants (but not the other two groups) expected the pills would be to swallow. These findings clearly demonstrate that the differing colours and shapes of pharmaceutical pills set-up significantly different expectations which likely play an important role in terms of people’s subsequent experience.     

The association between the colour of a container and the liquid inside: An experimental study on consumers’ perception,expectations and choices regarding mineral water

Multisensory interactions have been shown to affect food and beverage perception. Here we investigated if the colour of a plastic cup can affect the perception and expectation of the mineral water that is served in it. In Experiment 1, the participants were required to evaluate freshness, pleasantness, level of carbonation, and lightness of 3 different kind of mineral water (natural, slightly carbonated and carbonated) using visual analogue scales. The water was served in white, red, and blue plastic cups. In Experiment 2, we investigated the participants’ expectations regarding the water served in the same coloured plastic cups without tasting the liquid. In Experiment 3, we investigated if the participants chose to drink a given kind of water when served in a plastic cup of a specific colour. The results of Experiment 1 showed that people perceived mineral water as more carbonated when contained in a red or blue plastic cup, than when contained in a white cup. In Experiment 2, the participants expected the sparkling water contained in a blue cup to be less carbonated than the same water contained in a red or white cup and the slightly carbonated water more carbonated when served in a white or red cup with respect to the blue cup. Moreover, people expected the water to be fresher when contained in a white cup than in a red cup. In Experiment 3, the participants preferentially chose a white plastic cup to taste still water and blue or red cup to taste slightly sparkling water. These results clearly demonstrate that people’s perceptions, expectations, and choices regarding mineral water are differently modulated by the colour of the container where the liquid is served. The present study has important implications not only for understanding the multisensory interactions affecting beverage perception, but also for marketing and packaging design purposes.     

Heart rate,skin conductance,and explicit responses to juice samples with varying levels of expectation (dis)confirmation

Disconfirmations between consumers’ expectations and a product’s actual properties can lead to different responses in consumers. Most researchers study these responses focusing on the final judgement of the product. However, looking at consumers’ physiological responses like those of the autonomic nervous system (ANS) could help complement what is known about consumer reactions and final response to disconfirmed expectations. This study evaluated how ANS responses change when tasting juice samples that were as expected, that differed slightly, or that differed greatly from manipulated expectations and whether these responses vary from those obtained when there is no manipulation of expectations.Eighty-six participants tasted fruit and vegetable juices in two separate sessions. They were divided in two conditions. In Condition A, expectations were manipulated by showing participants the image of an ingredient and then providing them with a juice whose flavour was as expected, differed slightly, or differed greatly from that of the image. In Condition B, each juice was first tasted without explicit information shown beforehand and the image of the ingredient was shown afterwards. The images were the same as in Condition A. Heart rate and skin conductance were measured. To confirm that participants perceived confirmations and large and small disconfirmations when tasting the juices, they rated the samples in different sensory properties before and after tasting them. Results from most of the sensory ratings, except sourness and taste intensity, showed that participants perceived the designed confirmation and disconfirmation of expectations accordingly. Regarding ANS responses, heart rate had a larger increase during the second session than during the first. Skin conductance responses increased in Condition A but decreased in Condition B. In conclusion, our design managed to create confirmations and varying levels of disconfirmations. ANS responses did not capture them but seemed to capture factors like attention and the orientation response.     

Colour and shape of design elements of the packaging labels influence consumer expectations and hedonic judgments of specialty coffee

Packaging plays an important role on attracting the consumers’ attention and creating hedonic and sensory expectations, which may affect actual product experience. The present study aimed at investigating whether the colour and/or shape of design elements of packaging labels would influence sensory and hedonic judgments of specialty coffee by amateur consumers. Participants (n = 174) first evaluated their expectations of coffee acidity and sweetness by looking at the coffee package, and subsequently, their experience of the same attributes when tasting a cup of coffee, in addition to rating their liking and purchase intent. The experiment followed a 2 × 2, between-subject design for label type (green or pink, round or angular), and the same coffee was served to all participants. Multivariate analysis of variance was conducted in order to assess main effects of colour and shape of the design elements of the packaging labels as well as interactions on sensory and hedonic ratings. Both colour and shape significantly affected consumers’ sensory expectations (pre-tasting ratings) regarding the specialty coffee, but they had no significant effect on post-tasting (actual perception) sensory ratings. Interactions between colour × shape were found to affect the hedonic measures. The coffee associated with the congruent labels (i.e., angular/green or the round/pink) received higher liking and purchase intent ratings than the one associated with the incongruent labels (i.e., angular/pink and the round/green). The implications of these results for the design of coffee packaging that convey some functional benefit as well as possible directions for future research are discussed.     

Cup texture influences taste and tactile judgments in the evaluation of specialty coffee

It has been demonstrated previously that the surface textures of product packaging and servingware can impact the perceived taste and mouthfeel of various different foods and beverages. The present study was designed to investigate whether coffee cups with different surface textures would influence the judgment of taste and mouthfeel attributes in specialty coffee by experts (Q-graders) and amateur consumers alike. A total of 231 participants were tested in one of the three studies. A preliminary test conducted at a specialty coffee event in Russia indicated that rubbing a swatch of sandpaper whilst drinking coffee influenced perceived body and aftertaste qualities. In the two main studies (Experiment 1 for Q-graders, and Experiment 2 for amateurs), the participants evaluated a sample of specialty coffee (a different coffee in each study) served in either a smooth or a rough ceramic cup. The coffee was rated by the Q-graders as tasting significantly more acidic when sampled from the rough cup, as opposed to the smooth, whereas the amateurs perceived the coffee as being significantly sweeter when tasted from the smooth cup rather than from the rough cup instead. Both Q-graders and amateurs judged the aftertaste as significantly dryer when tasted from the rough rather than from the smooth cup. The perception of body was not significantly affected in any of the experiments. These results demonstrate that haptic cues influence the judgment of basic tastes as well as mouthfeel attributes in specialty coffee, for both experts and amateur consumers. Such results should be considered by the industry when designing innovative coatings for coffee cups. In addition to innovation, though, it is important to create cups that convey some functional and/or perceptual benefit for the coffee drinking experience.     

Consumer perceptions,attitudes and acceptance of new and traditional mate tea products

Consumption of teas has been increasing around the world. In Brazil, mate tea, prepared from yerba mate (Ilex paraguariensis), is the most popular tea and its popularity is increasing due to the development of new mate-based products and the increasing health consciousness of the Brazilian population. Further development of the mate market in Brazil requires accurate consumer profiling, focusing on tea drinking behavior, preferences and perceptions. We applied a questionnaire to mate tea consumers to assess their beliefs, consumption behavior, and taste preferences. We also explored the acceptability of tea made from yerba mate processed in different ways: immediately after harvest and after eight months of storage, varying the percentage of leaves and sticks. One hundred consumers evaluated six experimental samples and two commercial mate teas. Results indicated that mate was most consumed in tea bag form, followed by ice teas. The preferred flavors were natural and lemon. Most of the consumers (61%) consumed mate with sugar, drinking it at home before bedtime. Product quality, brand and price were the most important aspects taken into account when purchasing mate. The majority of consumers were not satisfied with the products currently offered in the market, and the main criticism was poor quality and packaging. Consumers accepted all tasted samples, except the tea prepared with 100% sticks. Commercial teas were less preferred than the experimental teas, indicating that there are opportunities for further development of commercially viable mate products.     

Influence of brand information on consumers’ expectations and liking of powdered drinks in central location tests

The aim of the present work was to study the influence of brand on consumers’ expectations and liking of orange-flavoured powdered drinks. Ten samples of orange-flavoured powdered drinks were evaluated by 108 consumers who scored their expected liking (looking at the pack only) and the overall liking under blind and informed-testing conditions (tasting the products). Consumers were also asked to answer a check-all-that-apply question with eight statements related to some products’ characteristics and usage occasions. Results showed that brand and package information had a large impact on consumers’ liking scores only for well-recognized brands. Hierarchical multiple factor analysis performed on liking scores for the three evaluation conditions showed that informed liking scores were closer to expected liking scores than to blind liking scores, suggesting that brand information was more important than hedonic reaction to the sensory characteristics in determining consumers’ liking scores for the samples on the informed condition.     

Diagonal or vertical? An empirical study of the impact of food brand logo orientation on consumers’ food perception and food attitude

This study explores the role of food brand logo orientation on consumers’ perceptions and attitudes regarding food products through four studies. Study 1 examines the effects of food brand logo orientation (diagonal vs. vertical) on consumer perceptions of food tastiness and risk. The findings suggest that diagonal (vs. vertical) food brand logos result in higher (lower) taste and risk perception in branded food. Study 2 reveals the underlying mechanisms of this effect by introducing perceived movement as a mediator between logo orientation and food perception. The results support the inference that movement is an underlying mechanism for the effect. Study 3 examines the effects of brand logo orientation and regulatory focus on consumer attitudes regarding branded food. The results suggest that for consumers with a promotion focus, a diagonal (vs. vertical) oriented logo leads to a more favorable attitude toward the food. For consumers with a prevention focus, a diagonal (vs. vertical) oriented logo leads to a less favorable attitude toward the food. Study 4 establishes validity of the above findings regarding native English speakers.     

Direct and mediated impacts of product and process characteristics on consumers’ choice of organic vs. conventional chicken

There is a lack of research into why consumers value process characteristics. In this study, we test the hypothesis that the impact of process characteristics such as organic and free-range on consumers’ choices of food products is at least partly mediated through expected eating quality or taste expectations. In other words, the process characteristics partly function as cues to (eating) quality. Using a traditional metric conjoint approach based on an additive model, four product characteristics (production method, price, size and information about farmer and rearing conditions) were varied in a fractional factorial conjoint design, creating nine profiles of whole chickens. 384 Respondents rated the nine different chickens in terms of taste expectations and willingness to buy. Since the nine records for each respondent are not independent, we used linear mixed modelling for the mediation analysis. We find that, as expected, taste expectations are a strong predictor of willingness to buy. As hypothesised, the impact of both product and process characteristics on willingness to buy is at least partly mediated through taste expectations. Hence, the study shows that process characteristics are important for consumers, not only in and off themselves, but partly because consumers make inferences about eating quality from knowledge about such process characteristics.     

Influence of three non-sensory factors on consumer choice of functional yogurts over regular ones

To better understanding the consumer choice of functional foods, a choice-based conjoint study was carried out to investigate the influence of three non-sensory factors on consumer choice of functional yogurts over regular ones. Four attributes were considered in the conjoint study: type of yogurt (regular, enriched with antioxidants and enriched with fibre), brand (national familiar, national unfamiliar, and foreign familiar), price (low, regular and high) and claim (with and without ‘reduced disease risk’ health claim). Eighteen choice sets, each composed of three stimuli (regular yogurt, enriched with antioxidants and enriched with fibre and varying the brand, price and claim levels) were evaluated by 103 consumers. For each choice set, consumers had to indicate which yogurt would normally buy. A questionnaire on consumer attitude towards health and nutrition was answered by participants after the choice task. Brand, price and health claims highly significantly affected consumer choice of functional yogurts. The relative importance of brand was similar to that of type of yogurt. Therefore, results suggested that non-sensory factors such as brand and price could have an important impact on consumer perception of functional foods. The impact of brand, price and health claims was affected by consumer interest in health issues.     

What’s in a name? The effects of sound symbolism and package shape on consumer responses to food products

In the global market, consumers are exposed to multiple brand names in unfamiliar languages. Even meaningless words can trigger certain semantic associations. This phenomenon is known as sound symbolism, i.e., the direct link between a sound and a meaning. Sound symbolism helps consumers to form product expectations based on unfamiliar brand names. Product expectations can be also formed based on various elements of packaging design, including colours, shapes and materials. This study investigated the effects of unfamiliar brand names (“Asahi” vs. “Ramune”), package shapes (round vs. angular) and product types (muesli cookie vs. butter cookie) varied in perceived healthiness (low vs. high) on perceived product healthfulness, product evaluation, taste expectations and purchase intention. General health interest (GHI) was used as the moderating variable. The results showed that package shape and product type significantly influenced the perceived product healthfulness of the two experimental products. Brand name alone did not affect consumer responses. However, the congruent combination of product shape and brand name (round “Ramune” cookie) was preferred to incongruent combinations. Furthermore, the congruent combinations (“Ramune” butter cookie and “Asahi” muesli cookie) were expected to taste better and were more likely to be purchased compared to incongruent combinations. These results suggest that congruency between the type of product, brand name, and package design is important for creating a successful brand strategy. The study also showed that the effects of sound symbolism and congruency on perceived product healthfulness are more pronounced for consumers with low interest in healthy eating. However, further research is needed to generalise our results to other product groups.     

Chinese consumers’ understanding and use of a food nutrition label and their determinants

This paper investigated Chinese consumers’ understanding and use of the Chinese food nutrition label and their determinants. Quantitative data were collected during March 2012 through a self-administrated structured questionnaire conducted in Beijing (n = 213) and Baoding city (n = 447). Questions assessed Chinese consumers’ use and understanding (objective and subjective) of food nutrition labels, nutrition knowledge (objective and subjective), socio-demographic characteristics, diet status, diet-health awareness, body mass index (BMI) and familiarity with food nutrition labels. A moderate degree of subjective understanding and a low degree of objective understanding of food nutrition labels were found among the participants, and 70% of the participants claimed to rarely or never use nutrition labels when shopping for food. Nutrition knowledge (objective and subjective) positively affected participants’ understanding (objective and subjective) of food nutrition labels. Familiarity with food nutrition labels had a strong positive effect on understanding of and use of food nutrition labels. Subjective nutrition knowledge and subjective understanding also played a significant and positive role in Chinese consumers’ label use. Age yielded a negative effect on both subjective and objective understanding, while education only affected participants’ objective understanding. None of the socio-demographic characteristics associated with self-reported use. Implications for future policies to improve Chinese consumers’ understanding and promote their use of food nutrition labels are discussed.     

Anchoring effect in judgments of objective fact and subjective preference

The way by which various sources of external information interact in their effects on judgment is rarely investigated. Here, we report two experiments that examine how two sources of external information—an anchor (a reference price) and an eco-label—influence judgments of an objective fact (product price) and a subjective preference (willingness-to-pay for the product). Participants’ price judgments were drawn in the direction of the anchor point, whereas the eco-label resulted in higher judgments of objective fact (Experiment 1) but did not influence subjective preference (Experiment 2). Interestingly, the eco-label seemed to strengthen the effect of the high anchor in judgments of objective fact. Further, participants with higher environmental concern answered a higher price on the subjective preference questions when they received a high anchor, as well as a lower price when they received a low anchor in comparison to the low environmental concern group. This study demonstrates that various external information sources can strengthen each other’s effects on consumer belief about products, while the effects are weaker for consumers’ preferences. The implications of the results for decision making are discussed.     

Tasting names: Systematic investigations of taste-speech sounds associations

Product names can be developed to effectively convey specific sensory attributes to the consumer. Most of the previous research on crossmodal correspondences has shown that people selectively associate words (e.g., ‘Maluma’, ‘Takete’) with taste attributes. To provide practical insights for naming new products in the food industry, it is important to obtain a more nuanced understanding concerning those properties of speech sounds (i.e., vowels, consonants) influencing people’s taste expectations. In this study, we investigated taste-speech sound correspondences by systematically manipulating the vowels and consonants comprising fictitious brand names. Based on the literature on crossmodal correspondences and sound symbolism, we investigated which vowels/consonants contribute more to the association between speech sounds and tastes (sweet/sour/salty/bitter). Across three experiments, we systematically varied vowels (front: [i][e], back: [a][u][o]), and affricate consonants (e.g., fricative: [f][s], stop: [p][t]) as well as voiced/voiceless consonants (e.g., voiced: [b][d], voiceless: [f][k]). Japanese participants were presented with brand names and had to evaluate the taste that they expected the product to have. The results revealed that: (1) front (back) vowels increased expected sweetness (bitterness), (2) fricative (stop) consonants increased expected sweetness (saltiness/bitterness), (3) voiceless (voiced) consonants increased expected sweetness/sourness (saltiness/bitterness). Moreover, consonants, which were pronounced first in the brand names, exerted a greater influence on expected taste than did the vowels. Taken together, these findings help advance theoretical foundations in sound-taste correspondences research as well as provide practical contributions to the food practitioners to develop predictive product names.
