Abstract This study explores artificial intelligence (AI) applications in menu design optimization within hospitality management. Grounded in choice architecture, arousal and S-O-R theories, it examines how AI-optimized/ menus influence consumer dining behaviors and physiological responses. Based on a baseline menu, ChatGPT enhanced it into three themes: sustainable, healthy, and mixed. A controlled laboratory experiment with […]

Emotional responses involve multiple components, including subjective experience and behavioral expression, which do not always align. Moreover, sex differences in emotional processing appear to vary across emotion types and response modalities. This study investigated sex differences and concordance between self-reported emotional experience and facial expressions elicited by naturalistic emotional video stimuli in a Korean adult […]

Background: Anorexia nervosa (AN) is a severe psychiatric disorder marked by restrictive eating, distorted body image, and high relapse rates. While cognitive-behavioral therapy (CBT) is a widely used treatment, its mechanisms of action in AN remain incompletely understood, particularly beyond self-reported symptom change. This study investigated the effects of a 12-week CBT intervention on both […]

AbstractObjective: Investigations of aesthetic experience have continually searched for field-research methodologies that measure physiological and self-report responses reliably and with little invasiveness. On this background, the interdisciplinary research project “ECR–Experimental Concert Research” set out to study aesthetic experience in live public concerts.Methods: A team of scientists from musicology, psychology, cultural studies, and software engineering were […]

Abstract: This study investigates the attentional and emotional impact of different image types in medical crowdfunding campaigns, and how these images impact donations. Building on signaling theory and evolutionary explanations for the drivers of altruism, we hypothesized that donors will be more likely to support campaigns with images that depict illness than campaigns with images […]

While emotional neutrality (e.g., maintaining a neutral face, speaking with a calm voice) can help entrepreneurs project a sought-after image of rationality, the effectiveness of such displays is context-dependent and gendered. In the emotionally resonant world of crowdfunding, the value of neutrality is ambiguous, as it may conflict with audience expectations of expressiveness. Building on […]

Abstract: The growing availability of facial expression databases (FEDBs) has accelerated the development of empathic AI systems designed to promote emotional awareness and well-being. However, most existing systems are trained solely on posed (acted), static databases featuring exaggerated and stereotypical displays. Such portrayals may not accurately represent the real-world expressions that are often subtle, heterogeneous, […]

Abstract Non-autistic observers often interpret autistic emotional expressions more negatively, though it is unclear whether this reflects observer bias or genuine differences in autistic people’s emotional experience and expression. To examine this, 20 autistic and 20 non-autistic adults reported the intensity of their felt emotion while re-experiencing video-recorded events eliciting mild and strong happiness, sadness, […]

Abstract: Objectives This research jointly combines voters. biometric facial expression analysis while viewing images of candidates and party logos with traditional surveys to define and quantify novel indicators of affective voting. The paper explains the innovative methodology and analyzes the results of the experiment carried out before the 2023 elections in Spain to understand how […]

Facial expressions are central to human interaction, yet their role in strategic decision-making has received limited attention. We investigate how real-time facial communication influences cooperation in repeated social dilemmas. In a laboratory experiment, participants play a repeated Prisoner’s Dilemma game under two conditions: in one, they observe their counterpart’s facial expressions via genderneutral avatars, and […]
