“…Our empirical results are also consistent with the predictions of recent work on driftdiffusion models that has considered settings in which the relative evaluations of decision alternatives are uncertain ex-ante and that has shown that the positive association between decision speed and decision quality dominates in such settings (see Fudenberg et al, 2018Fudenberg et al, , 2020. So far, drift-diffusion models have been mainly used to model decisions in simple decision problems and existing evidence is restricted to lab experiments with non-complex decisions (see, e.g., Ratcliff and Rouder, 1998;Krajbich and Rangel, 2011;Ratcliff et al, 2015;Bhui, 2019;Schotter and Trevino, 2021;Huseynov and Palma, 2021). Our results document that the relevance of drift-diffusion models with uncertain evaluations of decision alternatives extends to complex decision contexts.…”

This paper presents an empirical investigation of the relation between decision speed and decision quality for a real-world setting of cognitivelydemanding decisions in which the timing of decisions is endogenous: professional chess. Move-by-move data provide exceptionally detailed and precise information about decision times and decision quality, based on a comparison of actual decisions to a computational benchmark of best moves constructed using the artificial intelligence of a chess engine. The results reveal that faster decisions are associated with better performance. The findings are consistent with the predictions of procedural decision models like drift-diffusion-models in which decision makers sequentially acquire information about decision alternatives with uncertain valuations.

“…They are defined as the broad spectrum of dietary lifestyle-related modern consumer behaviours, including hours of meal intake, shortening the time to prepare meals, food preparation methods and eating speed [19,20]. The speed of information flow and decision making have gained importance in nutrition [21,22]. These aspects are related to eating speed, as one of the elements accompanying modern consumer life under time pressure.…”

Self-Reported Eating Speed Is Associated with Indicators of Obesity in Adults: A Systematic Review and Meta-Analysis

et al. 2021

Eating speed (ES) as a dietary behaviour has become a widely discussed factor for weight management and obesity. This study analysed the relationship between ES and anthropometric indicators of obesity, including BMI and waist circumference (WC) in adults. A search conducted of PubMed, Web of Science, Science Direct and Scopus found six longitudinal studies and fifteen cross-sectional studies published for further analysis. A quality assessment was performed with the MINORS checklist. Eight studies were included in the meta-analysis and almost all reviewed studies showed that ES was associated with BMI, and non-fast eaters had significantly lower BMI than fast eaters. Therefore, it was assumed that slowing down the ES may be an effective strategy for weight management and lowering obesity risk. There was also an association between WC and ES. Assessment of eating speed can be included in nutrition surveys to analyse obesity risk. More broadly, research is also needed to establish a validated and standardised methodology to determine eating speed. Further research needs to examine the links between eating speed, obesity, ethnicity, sex, food culture and chronic diseases.

“…However, it is possible that time constraints were not stringent enough so that people were able to consider multiple outcomes under the imposed time constraints. Moreover, previous research has shown that people may increase accumulation speed when time is limited (e.g., Huseynov & Palma., 2021). A second assumption is that longer response times increase the likelihood that other outcomes besides the first outcome are considered as well.…”

A Value Accumulation Account of Unhealthy Food Choices: Testing the Influence of Outcome Salience Under Varying Time Constraints

People often engage in unhealthy eating despite having an explicit goal to follow a healthy diet, especially under certain conditions such as a lack of time. A promising explanation from the value accumulation account is that food choices are based on the sequential consideration of the values of multiple outcomes, such as health and taste outcomes. Unhealthy choices may result if taste is considered before health. We examined whether making a health outcome more salient could alter this order, thereby leading to more healthy choices even under time pressure. Two studies examined the time-dependent effect of outcome values and salience on food choices. Participants first completed priming trials on which they rated food items on healthiness (health condition), tastiness (taste condition), or both healthiness and tastiness (control condition). They then completed blocks of binary choice trials between healthy and tasty items. The available response time was manipulated continuously in Study 1 (N = 161) and categorically in Study 2 (N = 318). As predicted, results showed that the values of health and taste outcomes influenced choices and that priming led to more choices in line with the primed outcomes even when time was scarce. We did not obtain support for the prediction that the priming effect is time-dependent in the sense that primed outcomes are considered before non-primed outcomes. Together, these findings suggest that increasing the value and salience of a health outcome may be effective ways to increase healthy choices, even under poor conditions such as time pressure.
