EmotionMeter: A Multimodal Framework for Recognizing Human Emotions

IEEE Transactions on Cybernetics, Journal Year: 2018, Volume and Issue: 49(3), P. 1110 - 1122

Published: Feb. 7, 2018

In this paper, we present a multimodal emotion recognition framework called EmotionMeter that combines brain waves and eye movements. To increase the feasibility wearability of in real-world applications, design six-electrode placement above ears to collect electroencephalography (EEG) signals. We combine EEG movements for integrating internal cognitive states external subconscious behaviors users improve accuracy EmotionMeter. The experimental results demonstrate modality fusion with deep neural networks can significantly enhance performance compared single modality, best mean 85.11% is achieved four emotions (happy, sad, fear, neutral). explore complementary characteristics their representational capacities identify has advantage classifying happy emotion, whereas outperform recognizing fear emotion. investigate stability over time, each subject performs experiments three times on different days. obtains 72.39% across sessions movement features. These effectiveness within between sessions.

Emotion fingerprints or emotion populations? A meta-analytic investigation of autonomic features of emotion categories.

Psychological Bulletin, Journal Year: 2018, Volume and Issue: 144(4), P. 343 - 393

The classical view of emotion hypothesizes that certain categories have a specific autonomic nervous system (ANS) "fingerprint" is distinct from other categories. Substantial ANS variation within category presumed to be epiphenomenal. theory constructed an population context-specific, highly variable instances need not share fingerprint. Instead, meaningful part the nature emotion. We present meta-analysis 202 studies measuring reactivity during lab-based inductions in nonclinical samples adults, using random effects, multilevel and multivariate pattern classification analysis test our hypotheses. found increases mean effect size for 59.4% variables across categories, but sizes did clearly distinguish 1 another. also observed significant categories; heterogeneity accounted moderate substantial percentage (i.e., I2 ≥ 30%) variability 54% these sizes.

Emotion words, emotion concepts, and emotional development in children: A constructionist hypothesis.

Developmental Psychology, Journal Year: 2019, Volume and Issue: 55(9), P. 1830 - 1849

Published: Aug. 29, 2019

In this article, we integrate two constructionist approaches-the theory of constructed emotion and rational constructivism-to introduce several novel hypotheses for understanding emotional development. We first discuss the hypothesis that categories are abstract conceptual, whose instances share a goal-based function in particular context but highly variable their affective, physical, perceptual features. Next, possibility development is process developing concepts, words may be critical part process. hypothesize infants children learn way they other conceptual categories-by observing others use same word to label events. Finally, can understood as concept construction problem: child becomes capable experiencing perceiving only when her brain develops capacity assemble ad hoc, situated concepts purposes guiding behavior giving meaning sensory inputs. Specifically, offer predictive processing account (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Perceptual and affective mechanisms in facial expression recognition: An integrative review

Cognition & Emotion, Journal Year: 2015, Volume and Issue: 30(6), P. 1081 - 1106

Published: July 25, 2015

Facial expressions of emotion involve a physical component morphological changes in face and an affective conveying information about the expresser's internal feelings. It remains unresolved how much recognition discrimination rely on perception patterns or processing content. This review research role visual emotional factors expression reached three major conclusions. First, behavioral, neurophysiological, computational measures indicate that basic are reliably recognized discriminated from one another, albeit effect may be inflated by use prototypical stimuli forced-choice responses. Second, content along dimensions valence arousal is extracted early facial expressions, although this coarse representation contributes minimally to categorical specific expressions. Third, configuration saliency features contribute significantly recognition, with "emotionless" models being able reproduce some phenomena demonstrated human observers. We conclude as it has been investigated conventional laboratory tasks, depends greater extent perceptual than mechanisms.

The Brain Basis for Misophonia

Current Biology, Journal Year: 2017, Volume and Issue: 27(4), P. 527 - 533

Published: Feb. 1, 2017

Misophonia is an affective sound-processing disorder characterized by the experience of strong negative emotions (anger and anxiety) in response to everyday sounds, such as those generated other people eating, drinking, chewing, breathing [1-8]. The commonplace nature these sounds (often referred "trigger sounds") makes misophonia a devastating for sufferers their families, yet nothing known about underlying mechanism. Using functional structural MRI coupled with physiological measurements, we demonstrate that misophonic subjects show specific trigger-sound-related responses brain body. Specifically, fMRI showed subjects, trigger elicit greatly exaggerated blood-oxygen-level-dependent (BOLD) anterior insular cortex (AIC), core hub "salience network" critical perception interoceptive signals emotion processing. Trigger misophonics were associated abnormal connectivity between AIC network regions responsible processing regulation emotions, including ventromedial prefrontal (vmPFC), posteromedial (PMC), hippocampus, amygdala. elicited heightened heart rate (HR) galvanic skin (GSR) which mediated activity. Questionnaire analysis perceived bodies differently: they scored higher on sensibility than controls, consistent functioning AIC. Finally, measurements implied greater myelination within vmPFC individuals. Overall, our results salience attributed particular based activation
