Inducing Novel Sound-Taste Correspondences via an Associative Learning Task.

The interest in crossmodal correspondences, including those involving sounds and involving tastes, has experienced rapid growth in recent years. However, the mechanisms underlying these correspondences are not well understood. In the present study (N = 302), we used an associative learning paradigm, based on previous literature using simple sounds with no consensual taste associations (i.

Can metaphors help us better remember wines? The effect of wine evaluation style on short-term recognition of red wines.

People are generally poor at remembering complex food stimuli, such as wine. While writing a description has been shown to improve memory performance, talking about wine is generally a difficult task for novices. However, giving novices a framework in which to evaluate the wine may help with the memory process.

Tasty vibes: Uncovering crossmodal correspondences between tactile vibrations and basic tastes.

The interest in crossmodal correspondences individually involving the senses of touch and taste has grown rapidly in the last few decades. Several correspondences involving different tactile dimensions (e.g.

Measuring Cognitive Abilities in the Wild: Validating a Population-Scale Game-Based Cognitive Assessment.

Rapid individual cognitive phenotyping holds the potential to revolutionize domains as wide-ranging as personalized learning, employment practices, and precision psychiatry. Going beyond limitations imposed by traditional lab-based experiments, new efforts have been underway toward greater ecological validity and participant diversity to capture the full range of individual differences in cognitive abilities and behaviors across the general population. Building on this, we developed Skill Lab, a novel game-based tool that simultaneously assesses a broad suite of cognitive abilities while providing an engaging narrative.

Assessing mechanisms behind crossmodal associations between visual textures and temperature concepts.

In the last decades, there has been a growing interest in crossmodal correspondences, including those involving temperature. However, only a few studies have explicitly examined the underlying mechanisms behind temperature-related correspondences. Here, we investigated the relative roles of an underlying affective mechanism and a semantic path (i.

Assessing the Satiation Efficacy of Imagined Eating.

Ubiquitous exposure to visual food content has been implicated in the development of obesity with both individual and societal costs. The development and increasing adoption of Extended Reality (XR) experiences, which deliver an unprecedented immersion in digital content, would seem to carry the risk of further exacerbating the consequences of visual food exposure on real-world eating behavior. However, some studies have also identified potentially health-promoting effects of exposure to visual food stimuli.

Design of experiments meets immersive environment: Optimising eating atmosphere using artificial neural network.

Design of experiments (DOE) is a family of statistical tools commonly used in food science to optimise recipes and facilitate new food development. In a novel cross-disciplinary twist, we propose to adapt DOE approach to the optimisation of restaurant atmosphere. In this study, an artificial neural network (ANN) with particle swarm optimisation algorithm (PSO; hereafter ANN-PSO) was selected and compared with classical Response Surface Method (RSM) as ANN-PSO has been reported to yield better reliability and predictability compared to RSM.

The sound of silence: Presence and absence of sound affects meal duration and hedonic eating experience.

The interplay between external auditory cues in the eating environment and cognitive processes, such as distraction, may influence food intake, but how and the degree to which they do is unclear. We report an experiment designed to investigate the effects of different sonic atmospheres on meal duration, food intake and evaluations, and responses to the sonic eating environment. In a quasi-naturalistic cafeteria setting, participants (N = 248) were eating a lunch meal whilst being in one of four conditions: slow music, fast music, cafeteria noise, and silence.

"Sound" Decisions: The Combined Role of Ambient Noise and Cognitive Regulation on the Neurophysiology of Food Cravings.

Our ability to evaluate long-term goals over immediate rewards is manifested in the brain's decision circuit. Simplistically, it can be divided into a fast, impulsive, reward "system 1" and a slow, deliberate, control "system 2." In a noisy eating environment, our cognitive resources may get depleted, potentially leading to cognitive overload, emotional arousal, and consequently more rash decisions, such as unhealthy food choices.

The impact of environmental sounds on food reward.

Wanting and liking are both components of food reward, but they manifest in fundamentally different neural substrates. While wanting denotes anticipatory and motivational behaviors, liking is associated with consummatory and hedonic experiences. These distinct constructs have also been quantitatively dissociated in behavioral paradigms.

Music Is Served: How Acoustic Interventions in Hospital Dining Environments Can Improve Patient Mealtime Wellbeing.

Eating-related challenges and discomforts arising from moderately acquired brain injuries (ABI)-including physiological and cognitive difficulties-can interfere with patients' eating experience and impede the recovery process. At the same time, external environmental factors have been proven to be influential in our mealtime experience. This experimental pilot study investigates whether redesigning the sonic environment in hospital dining areas can positively influence ABI patients' ( = 17) nutritional state and mealtime experience.

Commercializing Sonic Seasoning in Multisensory Offline Experiential Events and Online Tasting Experiences.

The term "sonic seasoning" refers to the deliberate pairing of sound/music with taste/flavour in order to enhance, or modify, the multisensory tasting experience. Although the recognition that people experience a multitude of crossmodal correspondences between stimuli in the auditory and chemical senses originally emerged from the psychophysics laboratory, the last decade has seen an explosion of interest in the use and application of sonic seasoning research findings, in a range of multisensory experiential events and online offerings. These marketing-led activations have included a variety of different approaches, from curating pre-composed music selections that have the appropriate sonic qualities (such as pitch or timbre), to the composition of bespoke music/soundscapes that match the specific taste/flavour of particular food or beverage products.

Metacognition and Crossmodal Correspondences Between Auditory Attributes and Saltiness in a Large Sample Study.

Mounting evidence demonstrates that people make surprisingly consistent associations between auditory attributes and a number of the commonly-agreed basic tastes. However, the sonic representation of (association with) saltiness has remained rather elusive. In the present study, a crowd-sourced online study ( n = 1819 participants) was conducted to determine the acoustical/musical attributes that best match saltiness, as well as participants' confidence levels in their choices.

Getting started with virtual reality for sensory and consumer science: Current practices and future perspectives.

While virtual reality (VR) has become increasingly popular in food-related research, there has been a lack of clarity, precision, and guidelines regarding what exactly constitutes a virtual reality study, as well as the options available to the researcher for designing and implementing it. This review provides a practical guide for sensory and consumer scientists interested in exploring the emerging opportunities offered by VR. We take a deep dive into the components that make up a VR study, including hardware, software, and response measurement methods, all the while being grounded in immersion and presence theory.

The temperature of emotions.

Emotions and temperature are closely related through embodied processes, and people seem to associate temperature concepts with emotions. While this relationship is often evidenced by everyday language (e.g.

How Digital Food Affects Our Analog Lives: The Impact of Food Photography on Healthy Eating Behavior.

Obesity continues to be a global issue. In recent years, researchers have started to question the role of our novel yet ubiquitous use of digital media in the development of obesity. With the recent COVID-19 outbreak affecting almost all aspects of society, many people have moved their social eating activities into the digital space, making the question as relevant as ever.

Sounds Healthy: Modelling sound-evoked consumer food choice through visual attention.

Food choice is a multifaceted construct that is not solely guided by our internal incentives. In fact, sensory scientist, consumer psychologists, and marketers have demonstrated that external ambient cues, including background music, can influence myriads of subconscious consumer behaviors, effectively leading to increased sales of food and beverages. However, the vast majority of literature in on this topic has thus far been confined to monocultural field studies in which the underlying mechanisms of food choice are unexplored.

Can Eating Make Us More Creative? A Multisensory Perspective.

While it is well known how food can make us physically healthy, it remains unclear how the multisensory experience of eating might influence complex cognitive abilities such as creativity. A growing body of literature has demonstrated that all human senses are capable of sparking creativity. It follows then that eating, as one of the most multisensory of all human behaviors, should be a playground for creative thinking.

A Dash of Virtual Milk: Altering Product Color in Virtual Reality Influences Flavor Perception of Cold-Brew Coffee.

It is well known that the appearance of food, particularly its color, can influence flavor perception and identification. However, food studies involving the manipulation of product color face inevitable limitations, from extrinsic flavors introduced by food coloring to the cost in development time and resources in order to produce different product variants. One solution lies in modern virtual reality (VR) technology, which has become increasingly accessible, sophisticated, and widespread over the past years.

The Effects of Ethnically Congruent Music on Eye Movements and Food Choice-A Cross-Cultural Comparison between Danish and Chinese Consumers.

Musical fit refers to the congruence between music and attributes of a food or product in context, which can prime consumer behavior through semantic networks in memory. The vast majority of research on this topic dealing with musical fit in a cultural context has thus far been limited to monocultural groups in field studies, where uncontrolled confounds can potentially influence the study outcome. To overcome these limitations, and in order to explore the effects of ethnically congruent music on visual attention and food choice across cultures, the present study recruited 199 participants from China ( = 98) and Denmark ( = 101) for an in-laboratory food choice paradigm with eye-tracking data collection.

Music to eat by: A systematic investigation of the relative importance of tempo and articulation on eating time.

Recent research has shown that eating behaviour is not only influenced by factors associated with the individual alone (e.g. psychological/physiological states) but also by the external factors determining the surrounding environment in which one eats (e.

Timing is everything: Onset timing moderates the crossmodal influence of background sound on taste perception.

Recent evidence demonstrates that the presentation of crossmodally corresponding auditory stimuli can modulate the taste and hedonic evaluation of various foods (an effect often called "sonic seasoning"). To further understand the mechanism underpinning such crossmodal effects, the time at which a soundtrack was presented relative to tasting was manipulated in a series of experiments. Participants heard two soundtracks corresponding to sweet and bitter tastes either exclusively during or after chocolate tasting (Experiment 1) or during and before chocolate tasting (Experiment 2).

Drinking through rosé-coloured glasses: Influence of wine colour on the perception of aroma and flavour in wine experts and novices.

Wine colour carries a myriad of meanings regarding the provenance and expected sensory qualities of a wine. That meaning is presumably learnt through association, and part of a wine taster's skill comes from being able to decode information that can be discerned in subtle variations in the colour of the wine that they drink/evaluate. However, reliance on colour means that wine tasters, especially experts, often exhibit colour-induced olfactory biases.
