“…Likewise, neither does explicit wanting, which expresses a conscious cognitive desire for a specific food group. These results indicate that being under the influence of acute stress is perhaps not enough to change perceived expected reward of foods, possibly because these subjective sensations can be linked to more stable individual preferences for specific foods [ 25 , 50 ]. The nature and longevity of the stress experience could be an important factor in this, as the strain felt after completing the stress-inducing cognitive task could have been regarded as manageable despite the high arousal levels.…”

“…Furthermore, reaction times for each trial were measured as a means for computing a measure of implicit wanting. In line with previous studies using the LFPQ implicit wanting score was calculated for each food category as a composite score for one food category relative to the other categories [ 40 , 47 , 50 ]. The score was calculated using the following algorithm and was based on frequency of choice, reaction time for both chosen and nonchosen foods, and a mean reaction time [ 40 , 47 ].…”

The link between acute stress, food pleasure and eating behavior in humans by employing measures of individual reward mechanisms has not been investigated as of yet. Having these insights is key to understanding why many people experience a change in eating behavior when experiencing stress. Thirty-five Danes (mean age 21.71 years) underwent a stress-inducing and relaxation-inducing task based on a randomized cross-over study design. Both tasks were combined with the Leeds Food Preference Questionnaire, to investigate the effect of stress on specific measures of food reward. Furthermore, participants chose a snack, as a covert measure of actual food choice. The study found no effect on explicit liking, explicit wanting or relative preference. For implicit wanting, an effect was detected on high-fat sweet foods, with increasing scores for the stress-induced condition. Moreover, 54% chose a different snack following the stress-inducing condition. Interestingly, 14% chose to change their snack choice to no snack at all. Results suggest acute psychosocial stress can increase cravings for highly palatable foods for some, while for others an experience of loss of appetite prevails. Overall, this study points to a further understanding of why consumers have issues with making healthy food choices, ultimately affecting public health too.

“…Even when specific to nature sounds, several experiments have been done on taste as outcome variable instead of craving or intake. Only a very recent experiment tested nature sounds with healthy food craving: ocean wave sounds increased explicit liking of healthy foods but not the craving for these foods (Peng- Li, Andersen et al, 2022). However, that experiment did not distinguish between loudness and the content of the sound.…”

“…Concerning the cognitive pathway, nature sounds sometimes ameliorated directed attention and response inhibition (Luo et al, 2021; Shu & Ma, 2020; Van Hedger et al, 2019). In fact, only one experiment tested a nature sound (i.e., ocean waves) as a determinant of healthy versus unhealthy food but it could not find an effect on wanting and was not able to control for sound volume as confounder (Peng-Li, Andersen et al, 2022). Hence, our second objective was to check the effect of nature sounds (bird and water sounds, independent of volume) toward reduced craving and healthier food choices.…”

This lab-based study tested whether nature sounds can lead to less stress reactivity, better stress recovery, less stress-induced eating and healthy food choice stimulation, while differentiating between bird and water sounds. Before (5 min) and after (8 min) the Trier Social Stress Test, 59 participants (47% men, 18–30 years) were exposed to one of three soundtracks: birds, streaming water, or wind as control. Group differences were tested on negative affect, salivary cortisol, heart rate variability, hunger, food craving, snack intake and influence expectations. Both bird and water sounds led to better cortisol recovery (not reactivity) and were reported to be more stress-reducing than wind only. The recovery effect was highest for water sounds. No differential sound effects were found for the food variables. The results confirm the potential implementation of bird and water sounds for stress restoration but future research should test the effects (especially on diet) in real-life settings.

“…Louder (vs. softer) ambient noise has consistently shown adverse effects on psychophysiological mechanisms, including increased arousal states ( Alvarsson et al, 2010 ) and cognitive load ( Mehta et al, 2012 ), potentially resulting in poorer decisions and unhealthier food choices ( Biswas et al, 2019 ; Volz et al, 2021 ; Peng-Li et al, 2022 ). These phenomena can be explained through the lenses of attentional processes and sensory overload ( Doucé and Adams, 2020 ), whereby “ louder noise may diminish the ability to attend to specific elements of the experience ” ( Bravo-Moncayo et al, 2020 ).…”

“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. Here, we investigated the combined impact of cognitive regulation and ambient noise on food cravings through neurophysiological activity. Thirty-seven participants were recruited for an adapted version of the Regulation of Craving (ROC) task. All participants underwent two sessions of the ROC task; once with soft ambient restaurant noise (∼50 dB) and once with loud ambient restaurant noise (∼70 dB), while data from electroencephalography (EEG), electrodermal activity (EDA), and self-reported craving were collected for all palatable food images presented in the task. The results indicated that thinking about future (“later”) consequences vs. immediate (“now”) sensations associated with the food decreased cravings, which were mediated by frontal EEG alpha power. Likewise, “later” trials also increased frontal alpha asymmetry (FAA) —an index for emotional motivation. Furthermore, loud (vs. soft) noise increased alpha, beta, and theta activity, but for theta activity, this was solely occurring during “later” trials. Similarly, EDA signal peak probability was also higher during loud noise. Collectively, our findings suggest that the presence of loud ambient noise in conjunction with prospective thinking can lead to the highest emotional arousal and cognitive load as measured by EDA and EEG, respectively, both of which are important in regulating cravings and decisions. Thus, exploring the combined effects of interoceptive regulation and exteroceptive cues on food-related decision-making could be methodologically advantageous in consumer neuroscience and entail theoretical, commercial, and managerial implications.
