Archetypal physiological responses to prolonged wakefulness
Acute sleep deprivation is a common workplace and lifestyle hazard known to affect physiological and cognitive performance. Previous research emphasizes the effect that sleep deprivation has on cognitive performance and often correlates changes in physiological parameters to measured performance. One potential problem with this approach is that there is some ambiguity about the true physiological […]
Preliminary results of a parametric analysis of emotions in a learning process in science
In the last decades, several studies have highlighted the importance of emotions in the teaching and learning process. The classroom is considered as an emotional place, where the learning is influenced by cognitive and emotional-motivational mechanisms. Classically, emotions have been classified in seven basics categories. Furthermore, in educational settings, it is possible to evaluate other […]
Cognitive and affective responses to marijuana prevention and educational messaging
Perceptions of risk of using marijuana have decreased significantly in the US over the last decade, while marijuana use has increased. In order to educate people on the risks associated with marijuana use, large-scale health messaging campaigns have been deployed to educate the public about the risks associated with marijuana use, particularly in states where […]
Exploring Visitors’ Visual Behavior Using Eye-Tracking: The Case of the “Studiolo Del Duca”
Although the understanding of cognitive disciplines has progressed, we know relatively little about how the human brain perceives art. Thanks to the growing interest in visual perception, eye-tracking technology has been increasingly used for studying the interaction between individuals and artworks. In this study, eye-tracking was used to provide insights into non-expert visitors’ visual behaviour […]
Pistol: Pupil Invisible Supportive Tool to extract Pupil, Iris, Eye Opening, Eye Movements, Pupil and Iris Gaze Vector, and 2D as well as 3D Gaze
This paper describes a feature extraction and gaze estimation software, named Pistol that can be used with Pupil Invisible projects and other eye trackers in the future. In offline mode, our software extracts multiple features from the eye including, the pupil and iris ellipse, eye aperture, pupil vector, iris vector, eye movement types from pupil […]
Data-driven analysis of gaze patterns in face perception: Methodological and clinical contributions
Gaze patterns during face perception have been shown to relate to psychiatric symptoms. Standard analysis of gaze behavior includes calculating fixations within arbitrarily predetermined areas of interest. In contrast to this approach, we present an objective, data-driven method for the analysis of gaze patterns and their relation to diagnostic test scores. This method was applied to […]
Developing tolerance to eye contact in autism: A feasibility study with adults using behavioral, interview, and psychophysiological data
Many individuals with autism report that eye contact makes them stressed or uncomfortable. Besides expressing their right to respect for neurodiverse ways of nonverbal communication, some autistic individuals also express the wish to improve their capacity to tolerate eye contact. In the current study, five autistic adults completed a 21- to 28-day computerized program that […]
Design of an SSVEP-based BCI Stimuli System for Attention-based Robot Navigation in Robotic Telepresence
Brain-computer interface (BCI)-based robotic telepresence provides an opportunity for people with disabilities to control robots remotely without any actual physical movement. However, traditional BCI systems usually require the user to select the navigation direction from visual stimuli in a fixed background, which makes it difficult to control the robot in a dynamic environment during the […]
Creation and validation of the Picture-Set of Young Children’s Affective Facial Expressions (PSYCAFE)
The immediate detection and correct processing of affective facial expressions are one of the most important competences in social interaction and thus a main subject in emotion and affect research. Generally, studies in these research domains, use pictures of adults who display affective facial expressions as experimental stimuli. However, for studies investigating developmental psychology and […]
Mobile News Learning — Investigating Political Knowledge Gains in a Social Media Newsfeed with Mobile Eye Tracking
This study investigates whether knowledge gains from news post exposure are different when scrolling through a social media news- feed on a smartphone compared to a desktop PC. While prior research has mostly focused on new platforms people receive news on (e.g., social media) for political learning, first indications exist that device modality (i.e. exposure […]
