Instagram's popular recipe videos showcase prominent cues, like taste and convenience, persuading viewers – particularly emerging adults (18-25) – to make the recipes. While hedonic taste cues trigger automatic appetitive responses, the processing of utilitarian convenience cues remains unclear. A within-subjects repeated-measures experiment with Instagram dessert recipe videos emphasizing taste , convenience , or both […]

Behavioral accounting examines how individuals interpret accounting information and how cognitive and emotional factors affect decision-making. An experiment with 43 participants, including accounting experts and students, was conducted to examine differences in the evaluation of financial data. Eyetracking, facial expression analysis, and biosensors were used to record visual attention and emotional responses during accounting tasks. […]

This thesis explores how spatial design in video game levels can be used to generate player tension and sustain fear, in the absence of enemies or direct threats. For the spatial design, the researcher focused on impossible or abnormal environmental structures, such as looping corridors, non-Euclidean layouts, and disorienting transitions, and how they can evoke […]

Purpose Social participation among wheelchair users depends heavily on mobility. While assistive navigation technologies like Google Maps have reshaped urban mobility, they often overlook the specific needs of wheelchair users. This study aimed to explore how wheelchair users interact with urban environments while using an assistive navigation technology and find gaps in route instructions, in […]

The study focuses on how young viewers visually process short-form videos on TikTok and how the distribution of attention between the main image and the platform interface changes in the process. In an exploratory laboratory experiment, 16 participants watched ten videos of four different types of content (lifestyle, educational content, fastpaced potentially risky videos, multi-screen […]

Abstract Facial expression has been proposed as a key mechanism in forming and maintaining social relationships. Humans have particularly expressive faces, but direct evidence linking individual level expressivity to group-level social bonding is limited. Here we examined whether spontaneous facial expressivity impacts social popularity during initial group formation. Participants (72 groups, N = 256) engaged […]

Intelligent Tutoring Systems (ITS) have advanced in personalized learning, but their ability to adapt to learners' emotional states is limited. This paper proposes an emotion-aware content adaptation framework using Reinforcement Learning (RL). A lightweight CNN extracts facial expressions and emotional features from video streams, which are then integrated with cognitive data. A Deep Q-Network (DQN) […]

Pilot in situ mobile eye‑tracking assessed visual attention to Gaudí’s Episcopal Palace (Astorga). Twenty‑eight participants freely viewed the chapel (n=14) or main façade (n=14) for 15 s. AOIs were delineated (18 chapel; 15 façade) on scene images; iMotions exported AOI coverage, TTFF, dwell time, fixation and revisit measures, supported by heatmaps. The chapel showed a […]

En un estudio piloto de seguimiento ocular móvil in situ se evaluó la atención visual hacia el Palacio Episcopal de Gaudí (Astorga). Veintiocho participantes observaron libremente la capilla (n = 14) o la fachada principal (n = 14) durante 15 segundos. Se delimitaron las áreas de interés (AOI) (18 en la capilla; 15 en la […]

Privacy policies are intended to support informed consent, yet users rarely read them fully. This study examines how common privacy policy interface structures influence attention allocation, reading behavior, and perceived experience. Using eye-tracking and post-task surveys, we compared three interface designs: continuous scrolling text, collapsible sections, and collapsible sections with brief previews. Results show that […]
