Predicting Emotion with Biosignals: A Comparison of Classification and Regression Models for Estimating Valence and Arousal Level Using Wearable Sensors

Sensors, 2023
This study aims to predict emotions using biosignals collected via wrist-worn sensor and evaluate the performance of different prediction models. Two dimensions of emotions were considered: valence and arousal.

Amines, Astrocytes, and Arousal [PDF]

Neuron, 2017
Amine neurotransmitters, such as noradrenaline, mediate arousal, attention, and reward in the CNS. New data suggest that, from flies to mammals, a major mechanism for amine transmitter action is to raise astrocyte [Ca2+]i and release gliotransmitters that modulate neuronal activity and behavior.

Variation in physiological and behavioral activity as reflected in changes in arousal level [PDF]

, 1972
The purpose of the present study was to investigate heart rate, skin conductance, and reaction time as reflected in changes in arousal level in an effort to resolve some of the conflict between the various interpretations of the activation process. Three

Multimodal Engagement Assessment in Children During Invented Story Paradigm With a Social Robot

Advanced Robotics Research, EarlyView.
A multimodal framework is proposed to assess children's engagement during storytelling interactions with a social robot. Gaze, physiological, and behavioral data are combined and validated against observer ratings. An automated gaze‐labeling strategy is introduced, and supervised classifiers achieve high accuracy. The study supports scalable engagement

Changes in physiological arousal during an arithmetic task: profiles of elementary school students and their associations with mindset, task performance and math grade

Scientific Reports
Task-related change in physiological arousal is suggested to reflect active involvement with the task. While studies often examine such task-related changes in arousal as averaged across the entire task, the present study focused on temporal changes in ...

Neurocalcin regulates nighttime sleep and arousal in Drosophila

eLife, 2019
Sleep-like states in diverse organisms can be separated into distinct stages, each with a characteristic arousal threshold. However, the molecular pathways underlying different sleep stages remain unclear. The fruit fly, Drosophila melanogaster, exhibits
