Advances in social cognition of obsessive-compulsive disorder / 中华行为医学与脑科学杂志

The main clinical features of obsessive-compulsive disorder (OCD) are obsessions and/or compulsions. Due to its symptoms are heterogeneous and have a wide range of influences, OCD usually causes different degrees of damage to patients' social functions. Social cognition is the process of perceiving and judging the psychology and behavior of others or oneself. Its core is to understand the information processing process and the underlying mechanism of social psychological phenomena. Studies have shown that social cognitive deficits can affect an individual's social function. Therefore, many scholars believe that the social cognitive function of OCD patients are impaired. Through collecting and sorting out relevant literature, we find that OCD patients can’t perceive social cues accurately, and they have trouble recognizing their own emotions and those of others. In general, they are not prone to emotional response, that is, their ability of emotional experience is impaired, while because of their own emotional regulation dysfunction, they overreact to special events that can induce the obsession and/or compulsion.The patients have poor insight into the mental states of others.The researches on attributions of life events are dificient, so their characteristics of attribution styles are not yet clear.These findings provide a preliminary theoretical basis and reference for the specificity of social cognitive impairment in patients with OCD and for guiding clinical effective and precise intervention.

O efeito moderador do sexo na correlação entre acurácia de percepção de emoções e sintomas depressivos / The moderate role of sex in the relationship between accuracy of perception of emotions and depressive symptoms

O interesse científico pelo processamento de informações emocionais cresceu nos últimos anos, indicando uma relação importante entre percepção de emoções e diversos transtornos mentais, dentre eles a depressão, além de estar relacionado a diferenças individuais em função do sexo. Dessa forma, o presente estudo teve por objetivo avaliar o papel moderador do sexo na relação entre sintomas depressivos e déficits na percepção de emoções de jovens adultos. Para tanto, participaram deste estudo 217 universitários, com idades entre 18 e 43 anos (M = 20,8; DP = 5,6), sendo 61,3% do sexo feminino. Foram aplicados um questionário sociodemográfico, Inventários de Depressão de Beck (BDI) e imagens do Picture of Facial Affects (PoFA). Os resultados indicaram correlações negativas fracas entre sintomas depressivos e déficits na acurácia de percepção de alegria, raiva, surpresa, expressões neutras e na acurácia total, com o sexo exercendo efeito moderador nas relações observadas. O conjunto dos resultados corroboram com achados da literatura internacional indicando a necessidade de se levar em consideração o sexo como importante variável durante a avaliação de déficits na percepção de emoções associados a sintomas depressivos.

Scientific interest in the processing of emotional information has grown in recent years, indicating an important relationship between the perception of emotions and various mental disorders, including depression, associated with being related to individual differences due to sex. In this way, the present study aimed to assess the moderating role of sex in the relationship between depressive symptoms and deficits in the perception of emotions in young adults. To this end, 217 university students, aged between 18 and 43 years (M = 20.8; SD = 5 A sociodemographic questionnaire, Beck Depression Inventories (BDI), and images from the Picture of Facial Affects (PoFA) were applied. The results indicated weak negative correlations between depressive symptoms and deficits in the accuracy of perception of joy, anger, surprise, neutral expressions, and in total accuracy, with sex having a moderating effect on the observed relationships. The set of results corroborates findings from the international literature indicating the need to take gender into account as a significant variable when assessing deficits in the perception of emotions are associated with depressive symptoms.

Using electroencephalogram for emotion recognition based on filter-bank long short-term memory networks / 生物医学工程学杂志

Emotion plays an important role in people's cognition and communication. By analyzing electroencephalogram (EEG) signals to identify internal emotions and feedback emotional information in an active or passive way, affective brain-computer interactions can effectively promote human-computer interaction. This paper focuses on emotion recognition using EEG. We systematically evaluate the performance of state-of-the-art feature extraction and classification methods with a public-available dataset for emotion analysis using physiological signals (DEAP). The common random split method will lead to high correlation between training and testing samples. Thus, we use block-wise

The association between neurocognitive functioning and clinical features of borderline personality disorder

Objective: To investigate the relationship between neurocognitive profiles and clinical manifestations of borderline personality disorder (BPD). Methods: Forty-five patients diagnosed with BPD and 35 healthy volunteers were included in the study. The BPD group was evaluated with the Borderline Personality Inventory for dissociative, impulsivity and suicidal dimensions. The Verbal Memory Processes Test and the Cambridge Neurophysiological Assessment Battery were administered to both the BPD and healthy control groups. Results: BPD patients differed from controls in sustained attention, facial emotion recognition, and deteriorated verbal memory function. A model consisting of the Dissociative Experiences Scale - Taxon (DES-T), motor impulsivity and Scale for Suicidal Behavior scores explained 52% of the variance in Borderline Personality Inventory scores. It was detected that motor impulsivity, decision-making and recognizing sadness may significantly predict DES-T scores, and response inhibition and facial emotion recognition scores may significantly predict impulsivity. Conclusion: Our findings demonstrate that the disassociation, impulsivity, and suicidality dimensions are sufficient to represent the clinical manifestations of BPD, that they are related to neurocognitive differences, and that they interact with clinical features.

Emotion Recognition Based on Multiple Physiological Signals / 中国医疗器械杂志

Emotion is a series of reactions triggered by a specific object or situation that affects a person's physiological state and can, therefore, be identified by physiological signals. This paper proposes an emotion recognition model. Extracted the features of physiological signals such as photoplethysmography, galvanic skin response, respiration amplitude, and skin temperature. The SVM-RFE-CBR(Recursive Feature Elimination-Correlation Bias Reduction-Support Vector Machine) algorithm was performed to select features and support vector machines for classification. Finally, the model was implemented on the DEAP dataset for an emotion recognition experiment. In the rating scale of valence, arousal, and dominance, the accuracy rates of 73.5%, 81.3%, and 76.1% were obtained respectively. The result shows that emotional recognition can be effectively performed by combining a variety of physiological signals.

The Influence of Anxiety on the Recognition of Facial Emotion Depends on the Emotion Category and Race of the Target Faces

The recognition of emotional facial expressions is critical for our social interactions. While some prior studies have shown that a high anxiety level is associated with more sensitive recognition of emotion, there are also reports supporting that anxiety did not affect or reduce the sensitivity to the recognition of facial emotions. To reconcile these results, here we investigated whether the effect of individual anxiety on the recognition of facial emotions is dependent on the emotion category and the race of the target faces. We found that, first, there was a significant positive correlation between the individual anxiety level and the recognition sensitivity for angry faces but not for sad or happy faces. Second, while the correlation was significant for both low- and high-intensity angry faces during the recognition of the observer's own-race faces, there was significant correlation only for low-intensity angry faces during the recognition of other-race faces. Collectively, our results suggest that the influence of anxiety on the recognition of facial emotions is flexible depending on the characteristics of the target face stimuli including emotion category and race.

Effects of Cognitive Behavioral Therapy, Existential Psychotherapy and Supportive Counselling on Facial Emotion Recognition Among Patients with Mild or Moderate Depression

OBJECTIVE: This study compared the effects of cognitive behavioral therapy (CBT), existential psychotherapy (ExP) and supportive counseling (SUP) on facial emotion recognition among mildly and moderately depressed patients. METHODS: 21 patients for CBT, and 20 each for ExP and SUP groups with 60 healthy controls were investigated. Eight consecutive weekly sessions and following two monthly boosters were performed. Prior to the sessions, all subjects received Sociodemographic Data Form, the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-1), and Facial Emotion Recognition Test (FERT). Patients received Hamilton Depression Rating Scale (HDRS) and FERT at the onset and after weekly and booster sessions. RESULTS: Patients' ability to recognize surprised and neutral emotions were lower than controls. ExP group improved recognition of almost all emotions, CBT group improved only happy emotions and SUP group did not improve any emotions. HDRS scores declined in all patient groups, ExP and CBT groups had lower scores than SUP. CONCLUSION: MDD patients recognized surprised and neutral emotions lower than controls. ExP improved ability to recognize almost all emotions, CBT improved only happy emotions, SUP did not improve at all. ExP, CBT and SUP all led to a reduction in MDD. ExP and CBT had comparable effects and both were more helpful than SUP.

Facial emotion recognition in patients with relapsing-remitting multiple sclerosis

@#Objective: Multiple sclerosis (MS) is an autoimmune disease of the central nervous system and the most common cause of disability among young adults. In addition to physical and cognitive disturbances, MS patients also have emotional processing deficits. Despite the rich knowledge available about cognitive impairments, little is known about emotion recognition in patients with relapsing-remitting MS (RRMS), despite the fact that it plays a key role in social behavior. The aim of our study was to investigate facial emotion recognition in patients with RRMS, compared with healthy controls. Methods: Facial emotion recognition abilities were studied in a homogeneous group of 51 RRMS patients and 51 healthy controls, using the Persian version of the Florida Affect Battery. We controlled both groups for physical symptoms, anxiety, depression and social dysfunction, using general health questionnaire (GHQ-28). Patients and healthy controls were matched according to age and gender. Early stage of the disease was defined as being diagnosed with RRMS and having an EDSS of 4 or lower. Results: MS patients performed as well as healthy controls in facial identity discrimination and facial emotion discrimination tasks, but showed significantly less performance in other subtests that required emotion recognition in comparison with healthy controls. Conclusions: Facial emotion recognition is impaired at early stages of MS. MS patients have problems in their emotional processing system. Deficits in facial emotion recognition merit attention because they might negatively influence interpersonal relationships and quality of life in MS patients.

Characteristic of emotion recognition ability to different facial expressions in impulsive violent criminals / 中国心理卫生杂志

Objective:To explore the difference of emotion recognition ability between impulsive violent criminals and the controls.Methods:Fifty-nine impulsive violent criminals were selected from 90 violent criminals in a prison.The control group consisted of 35 service workers and security guards recruited from a university.The 2 group (impulsive violent criminals group, control group) ×4 emotion (happiness, anger, sadness, fear) hybrid design was used in this study.The emotion recognition score, errors number and changed response number for each of the four emotions, including happiness, anger, sadness and fear, were obtained through an emotional expression multimorph task to investigate the difference of emotion recognition ability between the two groups.Results:Four participants with error rate more than 30％ were excluded.The effective data involved 58 impulsive violent criminals and 32 control subjects.The impulsive violent criminals had significant higher recognition scores of happiness [ (18.6±3.4) vs. (16.4±4.0), P＜0.01] and anger [ (16.2±2.4) vs. (14.1±3.2), P＜0.01] than the control group.In impulsive violent criminals, the recognition scores of facial expressions ranked from high to low were that of happiness, anger, fear and sadness (Ps＜0.05).In the control group, the recognition scores of facial expressions ranked from high to low were that of happiness, anger, fear/sadness (Ps＜0.05), but there was no significant difference between recognition scores of fear and sadness (P＞0.05).Conclusion:It suggests that the impulsive violent criminals might have a higher sensitivity to happy and angry facial expressions.

Research on electroencephalogram emotion recognition based on the feature fusion algorithm of auto regressive model and wavelet packet entropy / 生物医学工程学杂志

Focused on the world-wide issue of improving the accuracy of emotion recognition, this paper proposes an electroencephalogram (EEG) signal feature extraction algorithm based on wavelet packet energy entropy and auto-regressive (AR) model. The auto-regressive process can be approached to EEG signal as much as possible, and provide a wealth of spectral information with few parameters. The wavelet packet entropy reflects the spectral energy distribution of the signal in each frequency band. Combination of them gives a better reflect of the energy characteristics of EEG signals. Feature extraction and fusion are implemented based on kernel principal component analysis. Six emotional states from a public multimodal database for emotion analysis using physiological signals (DEAP) are recognized. The results show that the recognition accuracy of the proposed algorithm is more than 90%, and the highest recognition accuracy is 99.33%. It indicates that this algorithm can extract the feature of EEG emotion well, and it is a kind of effective emotion feature extraction algorithm, providing support to emotion recognition.

Study on Pulse Recordings of College Students with Different Emotional States / 世界科学技术-中医药现代化

This paper was aimed to investigate the changes of pulses under different emotional states.Based on the emotional pulse theory of traditional Chinese medicine (TCM),with college students as the research object,through films to stimulate different emotional expressions (i.e.,calm,sad and happy) of college students,the pulse recordings of college students were acquired in this study.The time domain parameters of pulses of college students under three types of emotional states were extracted.The difference among three groups of time-domain parameters was calculated by nonparametric test.Based on the time-domain parameters,the Support Vector Machine (SVM) classifier was used to classify three types of emotional states.The results showed that there were significant differences in three groups of time domain parameters (h3/h1,t and As/(As+Ad)).And the average recognition rate of three types of emotion states was 74.25％ based on the time-domain parameters of the pulse recordings.It was concluded that the pulse parameters can provide objective reference for emotional changes.It can be used to identify emotional states.

Diferencias de género en el reconocimiento de caras emocionales: ¿son los hombres menos eficientes? / Gender differences in the recognion of emoonal faces: are men less efficient?

Como indican las investigaciones sobre recuerdo de estímulos con valencia emocional, las emociones influyen sobre la memoria. Muchos estudios sobre reconocimiento de caras y expresiones faciales emocionales se han centrado en diferencias entre grupos de edad (jóvenes y mayores) o diferencias sexuales (hombres y mujeres). No obstante, este tipo de estudios ha arrojado resultados contradictorios, por lo que sería necesario profundizar en la implicación del género. El objetivo principal de nuestra investigación consiste en analizar las diferencias en el reconocimiento de fotografías de caras con expresiones faciales emocionales entre dos grupos, el primero compuesto por hombres y el segundo por mujeres, formados por estudiantes universitarios entre 18 y 30 años. Los resultados mostraron diferencias estadísticamente significativas en el reconocimiento de caras, presentando las mujeres un mejor reconocimiento corregido (probabilidad de aciertos menos probabilidad de falsas alarmas) que los hombres. Sin embargo, otras variables analizadas, como el tiempo o la eficiencia, no ofrecen resultados concluyentes. Además, en el grupo de varones se encontró una correlación negativa significativa entre el tiempo empleado y la eficiencia en la tarea. Estos datos proporcionan apoyo tanto a la hipótesis de la diferencia de género en el reconocimiento de caras, a favor de las mujeres, como a las que proponen un procesamiento cognitivo diferenciado de estímulos faciales en ambos sexos. Finalmente, se argumenta la necesidad de mayor investigación, relacionada con variables como la edad o el nivel social-cultural.

As research in recollection of stimuli with emotional valence indicates, emotions influence memory. Many studies in face and emotional facial expression recognition have focused on age (young and old people) and gender-associated (men and women) differences. Nevertheless, this kind of studies has produced contradictory results, because of that, it would be necessary to study gender involvement in depth. The main objective of our research consists of analyzing the differences in image recognition using faces with emotional facial expressions between two groups composed by university students aged 18-30. The first group is constituted by men and the second one by women. The results showed statistically significant differences in face corrected recognition (hit rate - false alarm rate): the women demonstrated a better recognition than the men. However, other analyzed variables as time or efficiency do not provide conclusive results. Furthermore, a significant negative correlation between the time used and the efficiency when doing the task was found in the male group. This information reinforces not only the hypothesis of gender difference in face recognition, in favor of women, but also these ones that suggest a different cognitive processing of facial stimuli in both sexes. Finally, we argue the necessity of a greater research related to variables as age or sociocultural level.

A influência da intensidade emocional no reconhecimento de emoções em faces por criancas brasileiras / The importance of emotional intensity on the recognition of facial emotions by Brazilian children

The ability to recognize emotions in faces is essential to human interaction and occurs since childhood. Hypothesis: research using the morphing technique assume that children require greater or lesser intensity of emotional expression to perceive it. Objective: to examine the emotional recognition of faces in childhood, using a task with emotional intensity variation. Method: it was applied a Test of Facial Emotion Recognition for Children to 28 children between 7 and 11 years, of both sexes, which presented 168 faces manipulated by the morphing technique, of the six basic emotions. Results: age as a trend growth of the likelihood of success at the task; more right answers for happiness and worst performances for fear; and the emotional intensity increasing at 42% the chance of success by every unit of intensity. Conclusion: these findings are relevant because they show the recognition of emotions at different levels as a more sensitive method.

Alteración del reconocimiento de emociones a través de movimientos corporales en traumatismo encéfalo craneano / Emotion recognition deficit from body movements after traumatic brain injury

Varios trabajos han documentado alteración de la capacidad para reconocer emociones como secuela del traumatismo encéfalo craneano (TEC), aunque la mayoría se focalizó en el estudio de las expresiones faciales. En este trabajo se analizó la capacidad para reconocer emociones básicas y complejas a partir de expresiones corporales y faciales, en un paciente con TEC (JA, hombre de 28 años de edad) y en un grupo control. Además se estudió el procesamiento facial y corporal no emocional. Los resultados mostraron afectación en el reconocimiento de emociones básicas y complejas a partir de expresiones corporales, en el paciente, así como dificultades para reconocer expresiones faciales de emociones complejas. JA no tuvo alteraciones en el reconocimiento de expresiones faciales de emociones básicas, ni en el procesamiento facial y corporal no emocional. Estos datos muestran la importancia de ampliar los estudios sobre reconocimiento de emociones, e incluir expresiones corporales además de las faciales.

Several works have documented deficit in emotional recognition after traumatic brain injury (TBI), although most of them focused on facial expressions only. In this study, we analyzed the ability to recognize basic and complex emotions from bodily and facial expressions, in a patient with TBI (JA, a 28 year old man) and a control group. We also studied non-emotional facial and body processing. Results showed deficit in basic and complex emotion recognition from bodily expressions, in the patient, and deficit to recognize facial expression of complex emotions. JA did not have alteration in recognition of facial expressions of basic emotions, and neither in non-emotional facial and body processing. These data show the importance of extending studies about emotional recognition, and include bodily expressions in addition of facial expressions.

Empatia e reconhecimento de expressões faciais de emoções básicas e complexas em estudantes de Medicina / Empathy and facial expression recognition of basic and complex emotions in medical students

RESUMO Objetivo Avaliar a empatia e a capacidade de reconhecimento de emoções básicas e complexas e suas correlações em estudantes de Medicina. Métodos O desenho do estudo foi transversal. Foram avaliados 86 alunos do 3º e 4º ano do curso de Medicina de uma faculdade de Medicina do interior do estado de São Paulo com os seguintes instrumentos: (i) escala Jefferson de empatia, (ii) tarefa de Reconhecimento de Expressões Faciais de emoções básicas (REF) e (iii) Reading the mind in the eyes test (RMEt). Resultados A média geral de acertos no REF foi 15,6 (DP: ±2,3). Houve diferença estatisticamente significante no número de acertos da emoção tristeza no sexo feminino comparado com o masculino (t84 = 2,30; p = 0,02). Em relação ao RMEt, a média geral de acertos foi de 26,5 (DP: ±3,3) com diferença estatisticamente significante entre os gêneros com maior número de acertos entre as estudantes do sexo feminino (t84 = 3,43; p < 0,01). O escore total médio na escala de empatia foi 121,3 (DP: ±9,8). Houve correlação positiva fraca entre o escore total da escala de empatia e o número de acertos para a emoção tristeza (r = 0,29; p < 0,01). Conclusão O número de acertos para a emoção tristeza no REF e o escore total do RMEt foi maior no sexo feminino comparado com sexo masculino. Além disso, a empatia parece estar diretamente relacionada com a capacidade de reconhecer a emoção tristeza. Outros estudos parecem pertinentes para avaliar de forma mais profunda aspectos de empatia e reconhecimento de expressões faciais da emoção em estudantes de medicina.

ABSTRACT Objective The aim was to evaluate empathy and facial expression recognition of basic and complex emotions and their correlations in medical students. Methods A cross-sectional study was performed in a medical school of the state of São Paulo. We evaluated 86 third and fourth year medical students with the following instruments: (i) Jefferson Scale of Empathy, (ii) Facial Expression Recognition of basic emotions task (REF) and (iii) Reading the Mind in the Eyes test (RMEt). Results The overall mean score in the REF was 15.6 (SD: ±2.3). There was a statistical significant difference in the number of correct responses in sadness emotion in female gender compared to male (t84 = 2.30; p = 0.02). Regarding RMEt, the overall mean score was 26.5 (SD: ±3.3) with statistically significant difference between genders with higher number of correct responses among female students (t84 = 3.43; p < 0.01). The mean score on the empathy scale was 121.3 (SD: ±9.8). There was significant weak positive correlation between the total score of empathy scale and the recognition of sadness facial emotion (r = 0.29; p < 0.01). Conclusion The number of correct responses to sadness emotion in the REF and the total score of RMEt was higher in female students compared to male. In addition, empathy seems to be directly related to the ability to recognize sadness. Other studies are needed to provide a deeper understanding of empathy and facial emotion recognition in medical students.

Difference of Facial Emotion Recognition and Discrimination between Children with Attention-Deficit Hyperactivity Disorder and Autism Spectrum Disorde

OBJECTIVES: This study aimed to investigate the differences in the facial emotion recognition and discrimination ability between children with attention-deficit hyperactivity disorder (ADHD) and autism spectrum disorder (ASD). METHODS: Fifty-three children aged 7 to 11 years participated in this study. Among them, 43 were diagnosed with ADHD and 10 with ASD. The parents of the participants completed the Korean version of the Child Behavior Checklist, ADHD Rating Scale and Conner's scale. The participants completed the Korean Wechsler Intelligence Scale for Children-fourth edition and Advanced Test of Attention (ATA), Penn Emotion Recognition Task and Penn Emotion Discrimination Task. The group differences in the facial emotion recognition and discrimination ability were analyzed by using analysis of covariance for the purpose of controlling the visual omission error index of ATA. RESULTS: The children with ADHD showed better recognition of happy and sad faces and less false positive neutral responses than those with ASD. Also, the children with ADHD recognized emotions better than those with ASD on female faces and in extreme facial expressions, but not on male faces or in mild facial expressions. We found no differences in the facial emotion discrimination between the children with ADHD and ASD. CONCLUSION: Our results suggest that children with ADHD recognize facial emotions better than children with ASD, but they still have deficits. Interventions which consider their different emotion recognition and discrimination abilities are needed.

Facial expression recognition in Alzheimer’s disease: a longitudinal study / Reconhecimento da expressão facial na doença de Alzheimer: um estudo longitudinal

Facial recognition is one of the most important aspects of social cognition. In this study, we investigate the patterns of change and the factors involved in the ability to recognize emotion in mild Alzheimer’s disease (AD). Through a longitudinal design, we assessed 30 people with AD. We used an experimental task that includes matching expressions with picture stimuli, labelling emotions and emotionally recognizing a stimulus situation. We observed a significant difference in the situational recognition task (p ≤ 0.05) between baseline and the second evaluation. The linear regression showed that cognition is a predictor of emotion recognition impairment (p ≤ 0.05). The ability to perceive emotions from facial expressions was impaired, particularly when the emotions presented were relatively subtle. Cognition is recruited to comprehend emotional situations in cases of mild dementia.

O reconhecimento da expressão facial é um dos aspectos mais importantes relacionados à cognição social. Foram investigados os padrões de mudança e os fatores envolvidos na habilidade de reconhecer emoções na doença de Alzheimer (DA) leve. Em um estudo longitudinal foram avaliadas 30 pessoas com DA. Para a avaliação da capacidade de reconhecimento facial na DA foi utilizada uma tarefa experimental que inclui a combinação de expressões com uma figura estímulo, rotulação da emoção e reconhecimento emocional de uma situação estímulo. Foi encontrada diferença significativa entre os momentos 1 e 2 na tarefa de reconhecimento situacional (p ≤ 0.05). A regressão linear mostrou que a cognição (p ≤ 0.05) é o fator preditor para o prejuízo do reconhecimento emocional, o que sugere um recrutamento da cognição para a compreensão de situações emocionais mais complexas. Houve comprometimento na percepção de emoções em expressões faciais, particularmente, quando as emoções eram sutis.
