Interoception primes negative emotion processing during cognitive reappraisal: Electroencephalographical evidence

Interoception, which refers to sensing, interpreting, and integrating internal bodily signals, has been suggested to be associated with emotion regulation. Previous research has demonstrated individual differences in interoception and its impact on emotion regulation. However, the priming effect of interoception on emotion regulation and the underlying neural mechanisms remain unknown. This study aims to examine how interoception primes different strategies of cognitive reappraisal, using electroencephalography (EEG). Thirty-seven healthy participants completed an interoceptive priming task. We found that interoception increased the amplitudes of the late positive potential (LPP) during both interpretation and detachment strategies. The priming effect of interoception in enhancing LPP amplitudes lasted longer for interpretation than for detachment. A decrease in alpha power during reinterpretation was observed after interoceptive priming, but not during detachment. The results revealed that interoception enhanced attention to bodily signals associated with negative emotions during cognitive reappraisal. Interoception showed distinct effects on different strategies of cognitive reappraisal, with different underlying neural mechanisms. Interoception-based programs may be an effective way to enhance the capacity for cognitive reappraisal.

Young Adults’ Perceptions of Adverse Childhood Experiences as Context and Causes of Mental Health Conditions: Observations from the United States

BackgroundThe relationship between adverse childhood experiences (ACEs) and mental health later in life has been well-established. However, first-person qualitative narratives describing how ACEs negatively impact mental health of young adults are rare. ObjectiveQualitative data explores how young adults with serious mental health conditions (SMHC) describe childhood adversities and relate those experiences to their mental health conditions. Participants and SettingYoung adult participants (n=55; ages 25-30) who self-reported being diagnosed with an SMHC were recruited from one state in United States. In-person interviews were conducted to gather narratives related to mental health, education, training, and employment. MethodsYoung adults with lived experience actively participated in the research process. Iterative coding and thematic analysis were employed to assess ACEs reported and analyze how participants described those experiences as influential. ResultsMost participants identified as White, non-Hispanic women. Major depression and anxiety disorders were the most prevalent diagnoses. Over 80% reported experiencing trauma, familial mental illness, or substance use challenges. Young adults connected their ACEs to fear and anxiety, emotional processing difficulties, poor coping behaviors, delayed help-seeking, and later negative interpersonal relationships. ConclusionsThis study is the first to qualitatively describe how young adults with SMHC describe ACEs and relate those experiences to their own mental health conditions. Future research should seek similar first-hand accounts in vulnerable populations and consider the unique impact of the COVID-19 pandemic. Findings and future research can inform policy, practice, and mental health treatment for young adults who have experienced ACEs, especially in the post-pandemic era.

Emotional Dissonance and Coping Strategies According to the Emotional Processing Type of Call Center Counselors

Background: This study explored the emotional processing types of call center counselors and examined the differences in emotional dissonance and related adaptation indicates of coping strategies, emotional exhaustion and work performance orientation according to the types.Methods: A total of 271 call center agents (204 females, 67 males; mean age 36.5) participated in the study. Latent class analysis of emotional awareness, emotional expression, ambivalence over emotional expression were conducted. Analysis of variance(ANOVA) was used to examine differences in adaptation indicators according to emotion processing type.Results: Emotional processing types were categorized into Clear(CG), Passive(PG) Repressive(RG) groups. The CG showed low emotional dissonance, good adaptation indicates and functional coping strategies whereas results for the RG type revealed the opposite.Conclusions: By distinguishing between emotional processing types, this study found that emotional processing type is more closely correlated with burnout and work performance orientation than emotional dissonance itself.

"Hot" affect-related aspects in emotional information processing: The role of facial muscle responses in the direct and indirect processing of emotion categories.

The present study investigated the involvement of facial muscle responses in the indirect and direct processing of emotional facial expressions. Five discrete emotion categories were used, and we assessed both facial muscle and behavioral responses on a trial-by-trial basis. Experiment 1 tested facial muscle activation of clearly visible stimuli in an emotion categorization task. We observed emotion-specific facial muscle responses and corresponding behavioral categorization effects, providing evidence for the specificity of facial muscle activation. By contrast, under masked indirect presentation conditions in which emotional facial expressions were presented as primes in an emotion misattribution procedure, a specific pattern of emotion-congruent and cross-category behavioral misattributions was observed (in line with Rohr et al., 2015, 2018). Multilevel analyses in Study 2 suggest that an emotional reaction feeds into the behavioral decision, as indicated by differential activation of the frontalis lateralis in response to angry faces. Thus, the present study provides evidence that facial muscle responses contribute to behavioral decisions under masked indirect processing conditions. The different pattern of effects in both studies suggests that facial muscle responses index different processes, depending on the processing conditions: sensorimotor simulation in direct processing conditions and emotional reactions in masked indirect processing conditions. We discuss the implications for models that aim to account for facial muscle activity in response to emotional facial expressions. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

인공지능 로봇의 도덕감정 함양 가능성에 대한 검토 -초등 도덕과를 중심으로-

This study examined the possibility of cultivating moral emotions of artificial intelligence robots that are developing recently. The 2022 revised elementary moral curriculum provides an opportunity for thought by asking questions about the relationship between artificial intelligence robots and humans. For the study, we first investigated the nature and expression process of emotions from ancient Western philosophy to modern brain science and neuroscience. Based on this, we explored what kind of emotional view the currently developed artificial intelligence robots express emotions based on. As a result, current artificial intelligence robots showed responses to humans using information accumulated through facial movements and facial expressions, focusing on basic emotions, according to Ekman's theory. This may be seen as a passive form based on human physical characteristics. However, moral emotion has a complex and active character that combines understanding of moral problem situations, empathy for others, and appropriate responses to situations. Accordingly, it was recommended to clearly teach the status and limitations of artificial intelligence robots in the field of current moral emotions in elementary moral education and educate students to form desirable relationships with artificial intelligence robots.

The impact of stimulus format and presentation order on social working memory updating.

Emotional faces and words have been extensively employed to examine cognitive emotional processing including social working memory, which plays a pivotal role in social interactions. However, it remains unclear which exact role these two stimulus formats play in updating specific emotional content, such as positive or negative information. Therefore, the current study examined the differences in working memory updating (WMU) of negative, neutral, and positive faces (Experiment 1) and words (Experiment 2), using a classic two-back paradigm with an event-related potential technique. In both experiments, emotional stimuli were presented in the same or different-valence order to further determine whether presentation order can also influence the WMU of specific emotional content. Our results showed that both stimulus format and presentation order play a role: (a) while faces showed an affective bias [larger P2 and late positive potential (LPP) for negative and positive faces than for neutral faces], words showed a negativity bias (larger LPP for negative words than both neutral and positive words); (b) While faces showed better performance with same-valence order, words showed better performance with different-valence order. Taken together, our findings indicate that, even if faces and words can contain the same emotional information, they impact social WMU differently.

TRPC4/5 inhibitors: Phase I results and proof of concept studies.

Transient receptor potential canonical (TRPC) ion channels are expressed in areas of the brain responsible for processing emotion and mood and have been implicated in the pathophysiology of internalizing disorders such as major depressive disorder and anxiety disorders. This review outlines the rationale for targeting TRPC ion channels for drug development, with specific focus on TRPC4 and TRPC5. We provide preclinical evidence that the lack of TRPC4 and TRPC5 channels or its pharmacological inhibition attenuate fear and anxiety without impairing other behaviors in mice. We also report on clinical studies of BI 1358894, a small molecule inhibitor of TRPC4/5 ion channels, demonstrating reduced psychological and physiological responses to induced anxiety/panic-like symptoms in healthy volunteers. Furthermore, we highlight an imaging study that investigated the acute effects of BI 1358894 and showed reduced activation in several brain regions involved in emotional processing. We conclude that these findings demonstrate a critical role for TRPC4 and TRPC5 in emotional processing, even though it remains an open question if the biological signatures of TRPC4/5 inhibition reported here translate into clinical efficacy and indicate that a TRPC4/5 inhibitor might provide a more effective treatment of internalizing disorders.

Neural Signature and Decoding of Unmanned Aerial Vehicle Operators in Emergency Scenarios Using Electroencephalography.

Brain-computer interface (BCI) offers a novel means of communication and control for individuals with disabilities and can also enhance the interactions between humans and machines for the broader population. This paper explores the brain neural signatures of unmanned aerial vehicle (UAV) operators in emergencies and develops an operator's electroencephalography (EEG) signals-based detection method for UAV emergencies. We found regularity characteristics similar to classic event-related potential (ERP) components like visual mismatch negativity (vMMN) and contingent negative variation (CNV). Source analysis revealed a sequential activation of the occipital, temporal, and frontal lobes following the onset of emergencies, corresponding to the processing of attention, emotion, and motor intention triggered by visual stimuli. Furthermore, an online detection system was implemented and tested. Experimental results showed that the system achieved an average accuracy of over 88% in detecting emergencies with a detection latency of 431.95 ms from the emergency onset. This work lays a foundation for understanding the brain activities of operators in emergencies and developing an EEG-based detection method for emergencies to assist UAV operations.

REM sleep and mental disorders on the 70th anniversary of the discovery of REM sleep.

The discovery of rapid eye movement sleep in 1953 led to numerous studies investigating the relationship between rapid eye movement sleep abnormalities and psychiatric disorders. The most salient findings were the association of rapid eye movement sleep alterations-reduced rapid eye movement sleep latency, increased rapid eye movement sleep volume of total sleep, and increased rapid eye movement density-with major depression. This paper briefly reviews the history of rapid eye movement sleep research in psychiatry with a focus on the work related to major depressive disorder and some of the various theories that have been proposed to explain the associated rapid eye movement sleep abnormalities. Given the increasing evidence that rapid eye movement sleep is important for emotional processing, memory and cognition, a better understanding of the underlying mechanisms for the relationship between rapid eye movement sleep and mood disorders could lead to improved treatments for these common and disabling illnesses.

TRANSITIVITY ANALYSIS OF SENATOR HAWLEY AND PROFESSOR BRIDGE’S GENDER IDENTITY DEBATE

Using Halliday’s transitivity concept, this paper analyzes the debate between Senator Hawley and Professor Bridges conducted on July 12, 2022. The debate focuses on the topic of people with a capacity for pregnancy, which led to views of gender identity. The way individuals identify their gender has become a social phenomenon, as the idea of gender has broadened to the point that it is seen as a spectrum. The creation of new words outside the two polarizations (i.e., man and woman) could create acknowledgment for the minority group of people with lesser-known gender identities. Using Halliday’s (1994) Transitivity Concept in Systemic Functional Linguistics, this study analyzes the clause structures of both Senator Hawley and Professor Bridges to examine the distribution of the six transitivity processes and their relation to the clauses chosen to represent each participant's ideology regarding their views on gender. The different approaches in their arguments regarding gender identity also show the different ideological beliefs of their parties, which are the Republicans and the Democrats. Senator Hawley dominantly uses mental processes consisting of the desideration process, cognition process, and emotion process. In comparison, Professor Bridges shows a high use of relational processes consisting of the attribution process and identification process. Professor Bridges' relational processes point out Senator Hawley's rigid idea of gender by identifying and valuing the variety of genders. The many clauses stated by Professor Bridges also affirm her liberal belief that views gender as more than just two polarizations while also supporting equality in the idea of abortion rights as something that is needed for women and other groups of genders. Senator Hawley counters Professor Bridges' allegations using mental processes by seeking clarification to align their awareness of gender, which reveals his gender polarization. The use of clauses mentioned by Senator Hawley is done to showcase his implied Republican ideology, which does not find significance in the topic of people with the capacity for pregnancy leading to transphobia.

Empirical evidence of the role of executive functions in tolerance of emotional distress

ABSTRACT Executive functions are domain general and therefore coordinate other processes, such as emotion regulation. One emotion regulation skill that has gained interest in the last decade is distress tolerance (DT), but its relationship with executive functions has been poorly explored. The aim of this study is to investigate the relationships between executive functions and self-perceived and behavioural DT. A total of 196 university students (age: M = 22.63 years; SD = 3.26) completed a Reading Span Task, the Five Digits Test, the Paced Auditory Serial Addition Task, and the Distress Tolerance Scale. Better executive functioning was related to higher self-perceived DT. Regarding behavioural DT, students with high DT showed greater cognitive flexibility and greater inhibition than students with low behavioural DT (no differences were found for working memory). The study contribute to the knowledge of the relationships between cognitive and emotional self-regulatory processes and provides a starting point for future research.

Towards a neurodevelopmental model of bipolar disorder: a critical review of trait- and state-related functional neuroimaging in adolescents and young adults.

Neurodevelopmental mechanisms are increasingly implicated in bipolar disorder (BD), highlighting the importance of their study in young persons. Neuroimaging studies have demonstrated a central role for frontotemporal corticolimbic brain systems that subserve processing and regulation of emotions, and processing of reward in adults with BD. As adolescence and young adulthood (AYA) is a time when fully syndromal BD often emerges, and when these brain systems undergo dynamic maturational changes, the AYA epoch is implicated as a critical period in the neurodevelopment of BD. Functional magnetic resonance imaging (fMRI) studies can be especially informative in identifying the functional neuroanatomy in adolescents and young adults with BD (BDAYA) and at high risk for BD (HR-BDAYA) that is related to acute mood states and trait vulnerability to the disorder. The identification of early emerging brain differences, trait- and state-based, can contribute to the elucidation of the developmental neuropathophysiology of BD, and to the generation of treatment and prevention targets. In this critical review, fMRI studies of BDAYA and HR-BDAYA are discussed, and a preliminary neurodevelopmental model is presented based on a convergence of literature that suggests early emerging dysfunction in subcortical (e.g., amygdalar, striatal, thalamic) and caudal and ventral cortical regions, especially ventral prefrontal cortex (vPFC) and insula, and connections among them, persisting as trait-related features. More rostral and dorsal cortical alterations, and bilaterality progress later, with lateralization, and direction of functional imaging findings differing by mood state. Altered functioning of these brain regions, and regions they are strongly connected to, are implicated in the range of symptoms seen in BD, such as the insula in interoception, precentral gyrus in motor changes, and prefrontal cortex in cognition. Current limitations, and outlook on the future use of neuroimaging evidence to inform interventions and prevent the onset of mood episodes in BDAYA, are outlined.

Exploring Emotion Control and Alexithymia in Autistic Adults: An Ecological Momentary Assessment Study.

Difficulties in controlling emotions - a proxy for emotion dysregulation (ED)-and difficulties in expressing feelings in words-'absence of emotion labelling' or alexithymia-co-exist in autism and contribute to elevated levels of impulsive and suicidal behaviour. To date, studies linking the two phenomena have relied on retrospective self-reported measures, lacking support for generalizability to real-life situations. The present study investigated in vivo emotion labelling and its impact on emotion control in 29 autistic adults without intellectual disability (ASC) and 28 neurotypical (NT) individuals of similar age, sex, and educational level. Participants were trained in an Ecological Momentary Assessment (EMA) to label their emotions, the arousal dimension, and their emotion control via smartphone over a one-week period. Findings showed that the ASC group experienced more instances of 'having an emotion that I cannot name' and, when they were able to label their emotions, they reported higher rates of negative and conflicting (simultaneously positive and negative) emotions. In both groups, the absence of emotion labelling, and intense negative emotions were associated with impaired emotion control. However, the association between lack of emotional awareness-'I have no emotion'-and impaired emotion control was only evident in ASC individuals. Our study highlights a nuanced facet of emotional processing in the ASC population. Further research is needed to gain a deeper understanding of the complex relationship between ED and alexithymia in autism.

The Influence of Temperament, Theory of Mind, Inhibitory Control, and Prosocial Behavior on Child Anxiety Symptoms in the First Five Years of Life.

Anxiety disorders are among the most prevalent of all mental health disorders, often originating in early childhood and extending into later childhood, adolescence, and adulthood. Determining salient risk factors that precede their development is important for prevention and intervention efforts. Towards this end, we examined the role of temperament, theory of mind, inhibitory control, and prosocial behavior on child anxiety symptoms in the first 5years of life. A community sample of children and their parents (N = 399) enrolled in a longitudinal study of emotion processing were assessed when the children were infants and at ages 2years, 3years, and 5years. Linear mixed models and linear regression models revealed that greater anxiety at 5years was associated with greater negative affectivity and behavioral inhibition, lower effortful control, lower theory of mind scores on the "desires" domain, and higher scores on the "intentions" domain (assessed from infancy to 3years of age). These characteristics may be useful to assess in clinical settings to evaluate a patient's risk for developing anxiety. They may also be useful in developinginterventions targeting specific vulnerabilities.

Clima socioemocional en el centro penitenciario de A Lama (Pontevedra, España)

This study examines the socioemotional climate in A Lama prison (Pontevedra, Spain). The study involved 153 participants, male (82.9 %), with an average age of 42.33 (SD = 11.40) years. Correlation analyses showed significant relationships between various affective processes, such as hope, solidarity, trust, and hatred, as well as associations between fear and the feeling of loneliness. Mediation analysis confirmed that educational opportunities for inmatesnot only increase joy but also reduce anger, contributing to a positive socioemotional climate. These results highlight the complexity of socioemotional experiences in the prison context, emphasizing the importance of simultaneously considering multiple emotional processes to gain a deeper understanding of the penitentiary socioemotional climate.

Association between biological markers and somatic pain

Pain, as one of the major clinical and social problems, still lacks effective objective evaluation indicators. At present, nearly one in five adults suffer from different types and different parts of pain. An important feature of clinical pain is persistent pain, in addition to sensory discrimination processes, it involves a range of brain regions involved in top-down cognitive and emotional processing. However, clinical pain is often affected by multiple factors and is difficult to assess objectively. Recently, blood, urine, cerebrospinal fluid, and biopsy tissue have been identified using novel, sensitive, and specific protein analysis methods in an attempt to detect changes in biological markers associated with different pain types. This paper will summarize the biological markers related to different parts of pain in the latest relevant studies at home and abroad and focus on the application prospect of such biological markers in the diagnosis, treatment, and prognosis evaluation of the pain.

Posttraumatic growth modulates the response to negative emotions related to COVID-19: An event-related potentials study.

There is increasing interest in identifying how posttraumatic growth (PTG) impacts emotional processing following traumatic events (e.g., the COVID-19 pandemic). Previous research suggests that high PTG levels may lead to enduring changes in positive emotional processing. Despite this fact, little is known regarding brain activation and responses to stressful emotional stimuli. The present study utilised event-related potentials (ERPs) to investigate whether individual differences in emotional responses toward neutral and negative emotional stimuli related to COVID-19 are related to self-reported PTG levels. A total of 77 participants were analysed: 21 in the high PTG group and 56 in the control group. The amplitude of the N2 was smaller in the high PTG group compared to the control group under both negative and neutral conditions. When viewing the negative emotion pictures (vs. neutral pictures), the N2 amplitude significantly decreased for the high PTG group in the right occipital and frontal-parietal areas, whereas no significant change was observed among the control group. In the time window Late Positive Potential (LPP) 600-1000ms, emotional stimuli and the group interaction were significant. Viewing negative pictures (vs. neutral pictures) decreased the LPP 600-1000ms amplitudes for the control group, mainly originating from the brain's frontal regions. However, there were no such significant differences for the PTG group. Due to the limited sample size and cultural differences, the applicability of these results to other regions or countries needs to be verified. The presented findings suggest that the impact of PTG during emotional response is reflected in both bottom-up (evidenced by the early ERP components) and top-down (evidenced by the later ERP components) processes. Individuals with high PTG may use a meditation-related emotional regulation strategy of acceptance at the basic stage and non-judgement at a later stage.

Cross-channel adaptation reveals shared emotion representation from face and biological motion.

Emotions in interpersonal interactions can be communicated simultaneously via various social signals such as face and biological motion (BM). Here, we demonstrate that even though BM and face are very different in visual properties, emotions conveyed by these two types of social signals involve dedicated and common processing mechanisms (N = 168, college students, 2020-2024). By utilizing the visual adaptation paradigm, we found that prolonged exposure to the happy BM biased the emotion perception of the subsequently presented morphed BM toward sad, and vice versus. The observed aftereffect disappeared when the BM adaptors were shown inverted, indicating that it arose from emotional information processing rather than being a result of adaptation to constitutive low-level features. Besides, such an aftereffect was also found for facial expressions and similarly vanished when the face adaptors were inverted. Critically, preexposure to emotional faces also exerted an adaptation aftereffect on the emotion perception of BMs. Furthermore, this cross-channel effect could not only happen from faces to BMs but also from BMs to faces, suggesting that emotion perception from face and BM are potentially driven by common underlying neural substrates. Overall, these findings highlighted a close coupling of BM and face emotion perception and suggested the existence of a dedicated emotional representation that can be shared across these two different types of social signals.

Disability and infidelity with a cross-cultural couple: an emotionally focused therapy case study

ABSTRACT This clinical case study delves into the therapeutic process of a cross-cultural couple, facing the intersection of disability and infidelity concerns. This intersection illuminates the intricate dynamics that arise when couples navigate both the complexities of disability and the emotional turmoil associated with infidelity. Utilizing Emotionally Focused Therapy (EFT), case intervention unfolded through three distinct stages, revealing intricate emotional dynamics, attachment styles, and communication patterns. The study explores the couples’ narrative, negative interaction cycles, and distinct emotional processing styles, considering complicating factors such as immigration challenges, cultural norms, and online infidelity. To strengthen bonds, the therapeutic approach promotes cultural sensitivity, intersectionality, and emotional connection. Despite time constraints and visa issues, the study highlights the efficacy of EFT in navigating the complexities of this cross-cultural couple. This case study contributes to the existing literature by examining the interplay of disability, infidelity, and cultural diversity within the framework of couples’ therapy.

Detecting five-pattern personality traits using eye movement features for observing emotional faces.

The five-pattern personality traits rooted in the theory of traditional Chinese medicine (TCM) have promising prospects for clinical application. However, they are currently assessed using a self-report scale, which may have certain limitations. Eye tracking technology, with its non-intrusive, objective, and culturally neutral characteristics, has become a powerful tool for revealing individual cognitive and emotional processes. Therefore, applying this technology for personality assessment is a promising approach. In this study, participants observed five emotional faces (anger, happy, calm, sad, and fear) selected from the Chinese Facial Affective Picture System. Utilizing artificial intelligence algorithms, we evaluated the feasibility of automatically identifying different traits of the five-pattern personality traits from participants' eye movement patterns. Based on the analysis of five supervised learning algorithms, we draw the following conclusions: The Lasso feature selection method and Logistic Regression achieve the highest prediction accuracy for most of the traits (TYa, SYa, SYi, TYi). This study develops a framework for predicting five-pattern personality traits using eye movement behavior, offering a novel approach for personality assessment in TCM.
