iMotions

Background: In order to test any process, product or system, it is important to understand the underlying human factors at play. A strong way to do this is through biosensor research. Simple sensors like those measuring eye-tracking, facial expression analysis, galvanic skin response, and heart rate can provide valuable information about how people...

ABSTRACT. The iMotions webcam based eye tracking (WebET), combined with the hidden markov models (HMM) for fixations classification is a potential tool for applied human behaviour research and teaching eye-tracking to larger cohorts. The present study explores the feasibility of carrying out large scale, replicable research projects. To verify how...

Methods: A validation study was run with n=10 (7 female, mean age 33 years, range 23-46). Participants were positioned 65cm from the webcam without chinrest and were shown stimuli on a 22" computer screen. A reading lamp illuminated the respondents' faces from the front. Webcam data was collected with a 30fps Logitech Brio camera with a resolution...

The Society for the Improvement of Psychological Science (SIPS) is an organization whose mission focuses on bringing together scholars who want to improve methods and practices in psychological science. The organization reaffirmed in June 2020 that “[we] cannot do good science without diverse voices,” and acknowledged that “right now the demographi...

Recent debates in the literature discuss commonalities between Attention-Deficit/Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD) at multiple levels of putative causal networks. This debate requires systematic comparisons between these disorders that have been studied in isolation in the past, employing potential markers of each dis...

Recent trends in literature, along with the changes to the Diagnostic and Statistical Manual (DSM), make it imperative to study Attention-Deficit/Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD) together, in order to better understand potential aetiological commonalities between these highly comorbid disorders. The present study exa...

Autism Spectrum Disorder (ASD) and Attention-Deficit/Hyperactivity Disorder (ADHD) represent two common neurodevelopmental disorders with considerable co-occurrence. Their comorbidity (ASD + ADHD) has been included in the latest diagnostic guidelines (DSM-V, 2013). The present study focuses on social visual attention that i) is a main aspect of soc...

Social interaction in individuals with Autism Spectrum Disorder (ASD) is characterized by qualitative impairments that highly impact quality of life. Bayesian theories in ASD frame an understanding of underlying mechanisms suggesting atypicalities in the evaluation of probabilistic links within the perceptual environment of the affected individual....

Recent discussions in the literature, along with the revision of the Diagnostic and Statistical Manual (DSM) (American Psychiatric Association 2013), suggest aetiological commonalities between the highly comorbid Attention-Deficit/Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD). Addressing this discussion requires studying these di...

The recording of eye movements is a unique method in the study of development in typical and atypical populations that has gained much valuable knowledge over the decades of its application. In the first part of this chapter, we question why and how we can, or should, study developmental processes, what eye movement recordings have taught us about...

Recent discussions in the literature, along with the revision of the Diagnostic and Statistical Manual (DSM) [2], suggest aetiological commonalities between the highly comorbid Attention-Deficit/Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD). Addressing this discussion requires studying these disorders together by comparing constr...

Recent trends in the literature suggest an etiological overlap between Attention-Deficit/Hyperactivity Disorder (ADHD) and Autism Spectrum Disorder (ASD), which since the DSM-5 can be co-morbidly diagnosed. In order to systematically compare these groups and find clues to shared underpinnings of these disorders, potential markers of each disorder n...

Background: The changes in DSM-5 allow for a comorbid diagnosis of Autism Spectrum Disorder (ASD) and Attention Deficit Hyperactivity Disorder (ADHD). Recent trends in the literature suggest an etiological overlap between the two disorders. In order to systematically compare these groups and find clues to shared underpinnings of these disorders, po...
