Determining Correlation Between Video Stimulus and Electrodermal Activity
… One of the physiological signals is the electrodermal activities (EDA) signal. We explore how video stimulus that might arouse fear affect the EDA signal. To better understand EDA signal, two different medians, a scene from a movie and a scene from a video game, were selected to arouse …

In-situ measurement of electrodermal activity during occupational therapy
… therapy setting, informative changes in electrodermal activity (EDA) can be detected using iCalm. iCalm is a small, wireless sensor developed at MIT that measures EDA and motion, worn on the wrist or above the ankle. Twenty-two children (ages 3-10) with a clinical diagnosis of SPD …

Electrodermal Activity as an Indicator of Sensory Processing in Typically Developing Children and Children with Autism Spectrum Disorders
… Autism Spectrum Disorder (ASD).</p> <p>Method: Electrodermal activity (EDA) during rest and in response to</p> <p>sensation was measured using skin conductance. Skin conductance</p> <p>measures were used to calculate ICC (Intraclass Correlation Coefficient)</p> <p>reliability in 14 children with …

Exploring the applicability of implicit relevance measures in varying reading speed for adaptive I.R. systems
… saccades), and physiology (pupil dilation, electrodermal activity). Based on the limited number of participants at our disposal we study how these measures react when addressing documents at three different reading rates. Most of the fixation-derived features are reported to differ …

A machine learning approach to predict emotional arousal and aggressive driving from EDA and heart rate signals
… emotional arousal using physiological signals, Electrodermal Activity (EDA) and Heart Rate (HR), collected via the Empatica E4 wristband in real-world driving conditions. A total of 25 drivers participated in this study. From the collected Electrodermal activity (EDA) and Heart Rate signals, 22 …

Navigating the Complex Interactions between Preinjury Characteristics and Postinjury Outcomes Following Mild Head Injury: Does Trait Mindfulness Play a Role?
… ‘underarousal’, as indicated by lower electrodermal activity, than their non-injured peers. Moreover, it was found that trait mindfulness was associated with higher levels of physiological arousal (i.e., greater electrodermal activity). Interestingly, results also showed that MHI …

Psychophysiological measures of mental effort and emotion within user research
… is described in Chapters 2 and 3, in which electrodermal activity (EDA) within a high fidelity combine simulator is used as a measure of mental effort. Due to both the natural complexity of operating a combine harvester and the relative lack of understanding of combine operators today, using …

Voluntary inhibition of reflex: Effects of consistent meditative practice
… displayed greater suppression of myocardial reactivity during a highly reflexive and stressful task. Meditative practice also predicted a rise in electrodermal activity during a relaxation task, contrary to expectations. These results support the concept that meditative practices may alter …

Reactions of psychotherapists in training to religious questions
… to religious questions posed by a mock client. Electrodermal activity served as an index of physiological arousal interpreted as anxiety. Thirteen psychotherapists in training at the University of North Texas were recruited. They participated in a simulated intake session with a mock client who …

Gender Differences in the Relation Between Locus of Control and Physiological Responses
… physiological responses of heart rate (HR) and electrodermal activity (EDA) was investigated in 30 males and 31 females during an arithmetic task. The Levenson's Internal, Powerful Others and Chance (IPC) scales (Levenson, 1974) were used to assess the various degrees of internality for each …

Detecting Human Memory Processes via Bio-Signals
… movement data, photoplethysmography (PPG), and electrodermal activity (EDA), can provide insight into various cognitive states. Previous work has shown that eye movements along with other bio-signals differ when viewing familiar versus unfamiliar faces. Signals such as heart rate (derived from …

HandWave : design and manufacture of a wearable wireless skin conductance sensor and housing
… and dedicated housing. The HandWave collects Electrodermal Activity (EDA) data by measuring skin conductance over a pair of electrodes. The EDA data signal is used to infer the excitement level of the subject. The injection-molded housing is affixed to the wrist of the subject, and the …

Deciphering Emotional Responses to Music: A Fusion of Psychophysiological Data Analysis and Bi-LSTM Predictive Modeling
… musical pieces. During these listening sessions, Electrodermal Activity (EDA) and Pulse Oximetry (POX) readings were collected, complemented by qualitative feedback from the participants. Our analysis focused on detecting recurring patterns and extracting meaningful insights from the data. In …

Do Olfactory Stimuli Increase Presence During Exposure Tasks: A Comparative Study
… was assessed via psychophysiological response (electrodermal activity), visual scanning, and self-report measures. Linear Mixed Modeling showed relationships between olfactory stimuli and presence ratings as well as self-reported anxiety levels, but not visual scanning or physiological arousal. …

Characterizing electrodermal responses during sleep in a 30-day ambulatory study
Electrodermal activity (EDA) refers to the electrical activity measured on and under the surface of the skin and has been used to study sleep, stress, and mood. While gathering this signal was once confined to the laboratory, it can now be acquired in ambulatory studies through commercially …

Circadian and Multi-day Rhythms in Generalized Tonic-Clonic Seizure: A Probabilistic Approach
… of GTCS events phase-locking to rhythms in wrist electrodermal activity (EDA), validating previous claims. Ambulatory sleep-wake cycles and EDA recorded by smart wristbands from more than 1,000 patients diagnosed with GTCS are analyzed. GTCS events are detected by an FDA-cleared algorithm on the …

Sympathetic Arousal During Approach-Avoidance Decision- Making
… stimulate eccrine gland activation. This eccrine activity changes the electrical properties of the skin, or electrodermal activity (EDA). EDA has been used widely to assess autonomic arousal during various paradigms. Research has demonstrated how autonomic arousal (1) occurs during the processing …
