Eye tracking en psychologie et neurosciences Q4 2025

This study investigates how explanation scope affects users’ understanding, trust, and attitude toward a recommender system (RS), and how these effects are mediated by visual attention and moderated by explanation modality. Drawing on eye-tracking data, we conducted a 3 (explanation scope: local, global, joint) × 2 (modality: text-only, text with illustrations) between-subjects experiment, with a control group with no explanation (N = 277). Results showed that joint explanations outperformed no-explanation conditions across all outcomes. Structural equat...Afficher plus

Climate communication plays a crucial role in motivating public engagement, yet its effectiveness can vary depending on how individuals process climate-related information. This study addresses the problem that people overestimate their knowledge about climate change, which may distort how they respond to communication efforts. The main aim of this research is to examine how overconfidence shapes the perception and evaluation of climate-related messages. To investigate this, an eye-tracking experiment with 98 participants was conducted, comparing respons...Afficher plus

With the rapid advancement of virtual technologies, virtual field trip (VFT) has attracted increasing attention as an innovative pedagogical approach in contemporary education. However, empirical evidence on their effectiveness in promoting students’ competency development—particularly in the area of social-emotional competency (SEC)—remains scarce. To address this issue, this study employed a combination of self-report questionnaires and eye-tracking technology, using emotional scores and eye-movement data to investigate the effects of emotional engagem...Afficher plus

During comprehension, various aspects of upcoming input can be anticipated. However, it is unclear to what extent listeners exploit suprasegmental information to facilitate lexical retrieval. In Japanese, a Kansai-dialect-specific pitch accent system and a sandhi rule create a situation where the final tone of certain modifiers is conditioned by the initial tone of the following noun, thereby making the upcoming tone predictable. Both Tokyo and Kansai speakers showed increased fixations on the target when its initial tone was predictable based on an all-...Afficher plus

Eye tracking has become an increasingly important tool in cognitive and developmental research, providing insights into processes that are difficult to measure otherwise. The majority of eye-tracking studies rely on accurate identification of fixations and Saccade Researchs in raw data using event classification algorithms (sometimes called fixation filters).

Intrasexual competition is when members of the same sex compete for access to desirable mates. In women, the use of non-physical strategies, such as verbal and indirect aggression, are often preferred to mitigate potential risks of being targeted or to prevent partner desertion.

Relatively little is known about how the production of delayed echolalia fits within the overall picture of autistic children's language ability, including receptive language. To date, no empirical studies have tested autistic children's comprehension of individual words within their delayed echoes. The present study aimed to establish proof-of-concept for a novel method of examining children's comprehension of individual wo...Afficher plus

Questions about early word knowledge pervade the literature on both typical and atypical language trajectories. To determine which words an infant knows, researchers have relied on two types of measures-caregiver-report and eye-gaze behavior.

What are the reasons for these misalignments in gold-standard tasks that are designed to investigate the same underlying construct, and can converg...Afficher plus
