Emotion Recognition Depends on Subjective Emotional Experience and Not on Facial
Emotion recognition depends on subjective emotional experience and not on facial expressivity: evidence from traumatic brain injury Travis Wearne1, Katherine Osborne-Crowley1, Hannah Rosenberg1, Marie Dethier2 & Skye McDonald1 1 School of Psychology, University of New South Wales, Sydney, NSW, Australia 2 Department of Psychology: Cognition and Behavior, University of Liege, Liege, Belgium Correspondence: Dr Travis A Wearne, School of Psychology, University of New South Wales, NSW, Australia, 2052 Email: [email protected] Number: (+612) 9385 3310 Abstract Background: Recognising how others feel is paramount to social situations and commonly disrupted following traumatic brain injury (TBI). This study tested whether problems identifying emotion in others following TBI is related to problems expressing or feeling emotion in oneself, as theoretical models place emotion perception in the context of accurate encoding and/or shared emotional experiences. Methods: Individuals with TBI (n = 27; 20 males) and controls (n = 28; 16 males) were tested on an emotion recognition task, and asked to adopt facial expressions and relay emotional memories according to the presentation of stimuli (word & photos). After each trial, participants were asked to self-report their feelings of happiness, anger and sadness. Judges that were blind to the presentation of stimuli assessed emotional facial expressivity. Results: Emotional experience was a unique predictor of affect recognition across all emotions while facial expressivity did not contribute to any of the regression models. Furthermore, difficulties in recognising emotion for individuals with TBI were no longer evident after cognitive ability and experience of emotion were entered into the analyses. Conclusions: Emotion perceptual difficulties following TBI may stem from an inability to experience affective states and may tie in with alexythymia in clinical conditions. -

Facial Emotion Recognition
Issue 1 | 2021 Facial Emotion Recognition Facial Emotion Recognition (FER) is the technology that analyses facial expressions from both static images and videos in order to reveal information on one’s emotional state.

Deep-Learning-Based Models for Pain Recognition: a Systematic Review
applied sciences Article Deep-Learning-Based Models for Pain Recognition: A Systematic Review Rasha M. Al-Eidan * , Hend Al-Khalifa and AbdulMalik Al-Salman College of Computer and Information Sciences, King Saud University, Riyadh 11451, Saudi Arabia; [email protected] (H.A.-K.); [email protected] (A.A.-S.) * Correspondence: [email protected] Received: 31 July 2020; Accepted: 27 August 2020; Published: 29 August 2020 Abstract: Traditional standards employed for pain assessment have many limitations. One such limitation is reliability linked to inter-observer variability. Therefore, there have been many approaches to automate the task of pain recognition. Recently, deep-learning methods have appeared to solve many challenges such as feature selection and cases with a small number of data sets. This study provides a systematic review of pain-recognition systems that are based on deep-learning models for the last two years. Furthermore, it presents the major deep-learning methods used in the review papers. Finally, it provides a discussion of the challenges and open issues. Keywords: pain assessment; pain recognition; deep learning; neural network; review; dataset 1. Introduction Deep learning is an important branch of machine learning used to solve many applications. It is a powerful way of achieving supervised learning. The history of deep learning has undergone different naming conventions and developments [1]. It was first referred to as cybernetics in the 1940s–1960s. Then, in the 1980s–1990s, it became known as connectionism. Finally, the phrase deep learning began to be utilized in 2006. There are also some names that are based on human knowledge. -
A Review of Alexithymia and Emotion Perception in Music, Odor, Taste, and Touch
MINI REVIEW published: 30 July 2021 doi: 10.3389/fpsyg.2021.707599 Beyond Face and Voice: A Review of Alexithymia and Emotion Perception in Music, Odor, Taste, and Touch Thomas Suslow* and Anette Kersting Department of Psychosomatic Medicine and Psychotherapy, University of Leipzig Medical Center, Leipzig, Germany Alexithymia is a clinically relevant personality trait characterized by deficits in recognizing and verbalizing one’s emotions. It has been shown that alexithymia is related to an impaired perception of external emotional stimuli, but previous research focused on emotion perception from faces and voices. Since sensory modalities represent rather distinct input channels it is important to know whether alexithymia also affects emotion perception in other modalities and expressive domains. The objective of our review was to summarize and systematically assess the literature on the impact of alexithymia on the perception of emotional (or hedonic) stimuli in music, odor, taste, and touch. Eleven relevant studies were identified. On the basis of the reviewed research, it can be preliminary concluded that alexithymia might be associated with deficits Edited by: in the perception of primarily negative but also positive emotions in music and a Mathias Weymar, University of Potsdam, Germany reduced perception of aversive taste.

With social distancing in place and various measures of lockdowns, it becomes significant to understand emotional responses on a great scale. In this paper, a study is presented that determines human emotions during COVID-19 using various machine learning (ML) approaches. To this end, various techniques such as Decision Trees (DT), Support Vector Machines (SVM), k-nearest neighbor (k-NN), Neural Networks (NN) and Naïve Bayes (NB) methods are used in determination of the human emotions. The mentioned techniques are used on a dataset namely Real World Worry dataset (RWWD) that was collected during COVID-19. The dataset, which covers eight emotions on a 9-point scale, grading their anxiety levels about the COVID-19 situation, was collected by using 2500 participants. The performance evaluation of the ML techniques on emotion prediction is carried out by using the accuracy score. Five-fold cross validation technique is also adopted in experiments. The experiment works show that the ML approaches are promising in determining the emotion in COVID- 19 RWWD. -

They consist of conscious mental reactions towards objects or situations and are associated with various physiological, behavioral, and cognitive changes. In this paper, we propose a comparative analysis between different machine learning and deep learning techniques, with and without feature selection, for binarily classifying the six basic emotions, namely anger, disgust, fear, joy, sadness, and surprise, into two symmetrical categorical classes (emotion and no emotion), using the physiological recordings and subjective ratings of valence, arousal, and dominance from the DEAP (Dataset for Emotion Analysis using EEG, Physiological and Video Signals) database. The results showed that the maximum classification accuracies for each emotion were: anger: 98.02%, joy:100%, surprise: 96%, disgust: 95%, fear: 90.75%, and sadness: 90.08%. In the case of four emotions (anger, disgust, fear, and sadness), the classification accuracies were higher without feature selection. -

DEAP: a Database for Emotion Analysis Using Physiological Signals
IEEE TRANS. AFFECTIVE COMPUTING 1 DEAP: A Database for Emotion Analysis using Physiological Signals Sander Koelstra, Student Member, IEEE, Christian M¨uhl, Mohammad Soleymani, Student Member, IEEE, Jong-Seok Lee, Member, IEEE, Ashkan Yazdani, Touradj Ebrahimi, Member, IEEE, Thierry Pun, Member, IEEE, Anton Nijholt, Member, IEEE, Ioannis Patras, Member, IEEE Abstract—We present a multimodal dataset for the analysis of human affective states. The electroencephalogram (EEG) and peripheral physiological signals of 32 participants were recorded as each watched 40 one-minute long excerpts of music videos. Participants rated each video in terms of the levels of arousal, valence, like/dislike, dominance and familiarity. For 22 of the 32 participants, frontal face video was also recorded. A novel method for stimuli selection is proposed using retrieval by affective tags from the last.fm website, video highlight detection and an online assessment tool. An extensive analysis of the participants’ ratings during the experiment is presented. Correlates between the EEG signal frequencies and the participants’ ratings are investigated. Methods and results are presented for single-trial classification of arousal, valence and like/dislike ratings using the modalities of EEG, peripheral physiological signals and multimedia content analysis. Finally, decision fusion of the classification results from the different modalities is performed. The dataset is made publicly available and we encourage other researchers to use it for testing their own affective state estimation methods.
