İki Dillilikte Duygusal Dil İşlemleme: Andaş Çeviride Öznel Duygulanım ve Bürünsel Belirteçler

Emotion, as part of the overall sensorimotor, introspective, and affective system, is an essential part of language comprehension within the framework of embodied semantics. As emotional state influences semantic and syntactic processing, emotional language processing has been shown to modulate mood as well. The reciprocal relationship between language and emotion has also been informative in bilingualism. Here we take a relatively underresearched type of bilingual processing, simultaneous interpreting, as a case of extreme bilingualism and investigate the effect of emotional language rendering in the L1 on subjective affect and prosodic markers of L2 output. 18 trainee interpreters were asked to simultaneously interpret three speeches in Turkish that varied in emotionality, valence (negative, neutral, and positive), and difficulty in English. Responses to emotional language processing were analysed based on participants’ self-reported positive and negative affect using the Positive and Negative Affect Schedule (PANAS) and three prosodic parameters (intensity, pitch, and fluency). Results showed that interpreting emotionally negative speech increased negative affect, whereas interpreting emotionally positive speech did not modify positive affect. Intensity generally reflected cognitive load. Pitch and fluency, in particular, were more sensitive to changes in the valence of the source speech.

ANCW: Affective norms for 4030 Chinese words.

Affective information contained in words is gaining increased attention among neurolinguists and psycholinguists around the world. This study established the Affective Norms for Chinese Words (ANCW) with valence, arousal, dominance, and concreteness ratings for 4030 words that were Chinese adaptations of the CET-4 (The National College English Test Band 4) official syllabus. Despite the existing Chinese affective norms such as the Chinese Affective Words System (CAWS), the ANCW provides much more and richer Chinese vocabulary. By using 7-point (ranging from 1 to 7) Likert scales in a paper-and-pencil procedure, we obtained ratings for all variables from 3717 Chinese undergraduates. The ANCW norms possessed good response reliability and were compatible with prior normative studies in Chinese. The pairwise correlation analysis revealed quadratic relations between valence and arousal, arousal and dominance, as well as valence and concreteness. Additionally, valence and dominance, as well as arousal and concreteness, presented a linear correlation, and concreteness and dominance were correlated. The ANCW provides reliable and standardized stimulus materials for further research involving emotional language processing.

An fNIRS investigation of novel expressed emotion stimulations in schizophrenia

Living in high expressed emotion (EE) environments tends to increase the relapse rate in schizophrenia (SZ). At present, the neural substrates responsible for high EE in SZ remain poorly understood. Functional near-infrared spectroscopy (fNIRS) may be of great use to quantitatively assess cortical hemodynamics and elucidate the pathophysiology of psychiatric disorders. In this study, we designed novel low- (positivity and warmth) and high-EE (criticism, negative emotion, and hostility) stimulations, in the form of audio, to investigate cortical hemodynamics. We used fNIRS to measure hemodynamic signals while participants listened to the recorded audio. Healthy controls (HCs, n=42) showed increased hemodynamic activation in the major language centers across EE stimulations, with stronger activation in Wernicke’s area during the processing of negative emotional language. Compared to HCs, people with SZ (n=41) exhibited smaller hemodynamic activation in the major language centers across EE stimulations. In addition, people with SZ showed weaker or insignificant hemodynamic deactivation in the medial prefrontal cortex. Notably, hemodynamic activation in SZ was found to be negatively correlated with the negative syndrome scale score at high EE. Our findings suggest that the neural mechanisms in SZ are altered and disrupted, especially during negative emotional language processing. This supports the feasibility of using the designed EE stimulations to assess people who are vulnerable to high-EE environments, such as SZ. Furthermore, our findings provide preliminary evidence for future research on functional neuroimaging biomarkers for people with psychiatric disorders.

Mood and gender effects in emotional word processing in unbalanced bilinguals

Aims and objectives: We aimed to explore the relationship between mood and emotional word processing in the bilingual context, as modulated by participants’ gender. Methodology: We presented mood-inducing film clips to 28 female and 28 male unbalanced Polish–English bilinguals to put them in positive and negative moods. Participants were asked to decide if native language (L1) and non-native language (L2) single words were positive, negative, or neutral (an emotive decision task). Data and analysis: We analysed participants’ subjective mood ratings pre- and post-experimentally together with speed (a linear mixed-effects model) and accuracy (a generalised mixed-effects model) of their responses to single L1 and L2 words. Findings: The results revealed an interaction between mood and language as dependent on word valence, whereby faster reaction times (RTs) were observed to L1 than L2 neutral words only in a positive mood and to L2 positive words in a positive than negative mood. We also observed a response facilitation in a positive compared to negative mood, yet only in females. Finally, we observed faster and more accurate responses to positive and negative compared to neutral words, irrespective of gender and language of operation. Altogether, the results suggest that mood influences how unbalanced bilinguals respond to emotional words and shed a novel light on the role of participants’ gender in emotional word processing. Originality: This study extends monolingual research on emotional word processing to the bilingual context and shows how word valence modulates the way unbalanced bilinguals, being put in positive and negative moods, respond to L1 and L2 words. Our results also offer novel insights into research on mood and language, demonstrating that females can be more susceptible to mood changes than males. Significance: Our results highlight the importance of controlling participants’ mood and gender in research on emotional language processing in both monolingual and bilingual contexts.

Laterality in Emotional Language Processing in First and Second Language.

Language is a cognitive function that is asymmetrically distributed across both hemispheres, with left dominance for most linguistic operations. One key question of interest in cognitive neuroscience studies is related to the contribution of both hemispheres in bilingualism. Previous work shows a difference of both hemispheres for auditory processing of emotional and non-emotional words in bilinguals and monolinguals. In this study, we examined the differences between both hemispheres in the processing of emotional and non-emotional words of mother tongue language and foreign language. Sixty university students with Persian mother tongue and English as their second language were included. Differences between hemispheres were compared using the dichotic listening test. We tested the effect of hemisphere, language and emotion and their interaction. The right ear (associated with the left hemisphere) showed an advantage for the processing of all words in the first language, and positive words in the second language. Overall, our findings support previous studies reporting left-hemispheric dominance in late bilinguals for processing auditory stimuli.

On the potential impact of directionality on emotion processing in interpreting

The main aim of the study is to investigate the process of interpreting emotionally-laden content in the two directions (i.e., L2>L1 vs. L1>L2). In line with previous research on bilingualism, there is a psychological distance when processing the non-native relative to the native tongue, reflecting a decreased sensitivity to affect-laden stimuli in L2 compared to L1. Yet thus far only little attention has been devoted to investigating how interpreters process emotionally-laden as compared to neutral stimuli when interpreting. Additionally, in the context of language processing in interpreting, previous studies have shown an interpreting asymmetry, pointing to more cognitively taxing operations engaged in interpreting in the L1-L2 than L2-L1 direction; however, it remains under-investigated whether emotion processing might be modulated by interpreting directionality. To this aim, in the present pilot study, five professional interpreters were asked to interpret negatively-valenced as well as neutral sentences, both from Polish (L1) into English (L2) and in the opposite direction. To measure emotional responding, skin conductance (SC) method was triangulated with a self-report measure (SUPIN S30, the Polish adaptation of the PANAS questionnaire, Positive and Negative Affect Schedule). The obtained results showed an increased emotional responding, as reflected in SC results, in the process of interpreting a negatively-valenced compared to neutral content, irrespective of interpreting direction. The obtained results may contribute to research on emotional language processing in the context of interpreting.

The Pacified Face: Early Embodiment Processes and the Use of Dummies.

Few things affect us as much as facial expressions, as they inform us about others’ feelings and intentions, thereby influencing our own emotions and behaviors. A substantial body of literature links the critical abilities of recognizing and understanding emotion displays with facial mimicry, a sensorimotor process involving rapid imitation of perceived expressions. For example, blocking or altering facial mimicry in adults leads to disruptions in judgments in emotion recognition or emotional language processing. The present review focuses on pacifier use in infancy, a common practice that has the potential to interfere with infants’ facial movements in ways identical to laboratory paradigms designed to block facial mimicry. Despite this similarity and the widespread use of infant soothers, little is known about their long-term effects. Here we review studies exploring the psychological correlates and implications of pacifier use. In particular, we discuss how soothers may interfere with the development of social skills in infants and present evidence linking pacifier use with disrupted adults’ mimicry of facial expressions displayed by infants. Other preliminary findings reveal negative correlations between the use of soothers and children’s spontaneous facial mimicry as well as emotional competence of young adults. Such studies, although correlational, suggest that this widespread parenting practice may affect the development of social skills by influencing emotional coordination. We discuss the implications of these findings and propose avenues for future research that can provide insights into the role of embodied processes in the development of emotional competence and adult functioning.

Spanish affective normative data for 1,406 words rated by children and adolescents (SANDchild).

Most research on the relationship between emotion and language in children relies on the use of words whose affective properties have been assessed by adults. To overcome this limitation, in the current study we introduce SANDchild, the Spanish affective database for children. This dataset reports ratings in the valence and the arousal dimensions for a large corpus of 1406 Spanish words rated by a large sample of 1276 children and adolescents from four different age groups (7, 9, 11 and 13 years old). We observed high inter-rater reliabilities for both valence and arousal in the four age groups. However, some age differences were found. In this sense, ratings for both valence and arousal decreased with age. Furthermore, the youngest children consider more words to be positive than adolescents. We also found sex differences in valence scores since boys gave higher valence ratings than girls, while girls considered more words to be negative than boys. The norms provided in this database will allow us to further extend our knowledge on the acquisition, development and processing of emotional language from childhood to adolescence.

情绪词加工过程及其情绪效应特点：ERP的证据

<p id="C2">Language plays an important role in the exchange of emotional information. The processing of emotional language has always been the focus of emotional research. Some main views and results on emotional words processing from ERP data are analyzed and summarized: including ERP components and relationship between valence and arousal, as well as emotional effect characteristics. ERP components related to emotional word processing encompass very early P1-N1 components, early EPN components, and late LPP components. Emotional valence and arousal dimensions have shown to function as two significant factors in emotional word processing. Their relationship, however, remains undetermined. Compared with emotional pictures, emotional word processing exerts a weaker emotional effect, showing a bias towards positive valence. Future studies are required to explore relevant factors influencing emotional effect of emotional word processing, to distinguish emotional-laden words from emotional-label words, and to analyze the processing of these two types of emotional words. In addition, it is also an important topic for a future research to elucidate the emotional word processing mechanism in natural context reading by using eye-tracking technique.

Emotion in Context: How Sender Predictability and Identity Affect Processing of Words as Imminent Personality Feedback.

Recent findings suggest that communicative context affects the timing and magnitude of emotion effects in word processing. In particular, social attributions seem to be one important source of plasticity for the processing of affectively charged language. Here, we investigate the timing and magnitude of ERP responses toward positive, neutral, and negative trait adjectives during the anticipation of putative socio-evaluative feedback from different senders (human and computer) varying in predictability. In the first experiment, during word presentation participants could not anticipate whether a human or a randomly acting computer sender was about to give feedback. Here, a main effect of emotion was observed only on the late positive potential (LPP), showing larger amplitudes for positive compared to neutral adjectives. In the second study the same stimuli and set-up were used, but a block-wise presentation was realized, resulting in fixed and fully predictable sender identity. Feedback was supposedly given by an expert (psychotherapist), a layperson (unknown human), and again by a randomly acting computer. Main effects of emotion started with an increased P1 for negative adjectives, followed by effects at the N1 and early posterior negativity (EPN), showing both largest amplitudes for positive words, as well as for the LPP, where positive and negative words elicited larger amplitudes than neutral words. An interaction revealed that emotional LPP modulations occurred only for a human sender. Finally, regardless of content, anticipating human feedback led to larger P1 and P3 components, being highest for the putative expert. These findings demonstrate the malleability of emotional language processing by social contexts. When clear predictions can be made, our brains rapidly differentiate between emotional and neutral information, as well as between different senders. Attributed human presence affects emotional language processing already during feedback anticipation, in line with a selective gating of attentional resources via anticipatory social significance attributions. By contrast, emotion effects occur much later, when crucial social context information is still missing. These findings demonstrate the context-dependence of emotion effects in word processing and are particularly relevant since virtual communication with unknown senders, whose identity is inferred rather than perceived, has become reality for millions of people.

On Modality Effects in Bilingual Emotional Language Processing: Evidence from Galvanic Skin Response

Though previous research has shown a decreased sensitivity to emotionally-laden linguistic stimuli presented in the non-native (L2) compared to the native language (L1), studies conducted thus far have not examined how different modalities influence bilingual emotional language processing. The present experiment was therefore aimed at investigating how late proficient Polish (L1)–English (L2) bilinguals process emotionally-laden narratives presented in L1 and L2, in the visual and auditory modality. To this aim, we employed the galvanic skin response (GSR) method and a self-report measure (Polish adaptation of the PANAS questionnaire). The GSR findings showed a reduced galvanic skin response to L2 relative to L1, thus suggesting a decreased reactivity to emotional stimuli in L2. Additionally, we observed a more pronounced skin conductance level to visual than auditory stimuli, yet only in L1, which might be accounted for by a self-reference effect that may have been modulated by both language and modality.

Processing of emotional information in written language

Language conveys both semantic and emotional information. Emotional processing in language could not be easily explained by the current word recognition model, sentence processing model and discourse comprehension model. In order to uncover the characteristics of emotional processing in written language, the present review attempted to integrate findings from behavioral, event-related potential (ERP), and functional magnetic resonance imagining (fMRI) studies on emotional processing at multiple scales, such as words, sentences and discourses levels. First, previous studies have shown both automatic and controlled processes at different stages of emotional words processing. Some early ERP effects (before 300 ms: such as N1/P1, P2, EPN) as well as the activation of subcortical region (such as amygdala) have been taken as evidences for the rapid and automatic emotional processing. Some late ERP effects (such as late positive component after 500 ms) and the recruitment of higher-order brain areas (such as medial prefrontal cortex and cingulate cortex) have been suggested to reflect the controlled processing of the emotion words. In addition, emotional connotation could enhance cortical responses at all stages of visual word processing such as the assembly of visual word form (up to 200 ms), semantic access (around 200 ms), allocation of attentional resources (around 300 ms), contextual analysis (around 400 ms), and sustained processing (around 500 ms). Moreover, the network of word reading is influenced by the emotional network as manifested by the enhanced engagement of lexical-semantic network when processing emotional words compared to neutral words. However, it remains unclear regarding the time locus of emotional effect with respect to the lexical access. Another important finding is that emotional words obtained prioritized processing no matter when they were presented in isolation or shown in contexts. The salience of emotion information could override detailed semantic analysis, as indicated by the lack of semantic violation effect when the violations occurred to emotion words. Also, the emotional dimension of sentences was prioritized when the emotional words were embedded in sentences, as indicated by the N400 effect to emotion words following neutral congruent contexts. Moreover, the influence of emotional word on sentence processing was sustained, as suggested by its influence on the processing of its following words in sentences. Finally, we showed that emotion can be induced directly by emotional words or implied by a series of neutral words (for example, ″The boy fell asleep and never woke up again″). Both types of emotional sentences activated emotional brain network (such as amygdala, insula, medial prefrontal cortex), which in turn enhanced the involvement of language network (such as inferior frontal gyrus, middle temporal gyrus) compared to neutral sentences. Therefore, the language and emotional networks are highly interactive. Overall, the current review summarized main findings regarding emotional processing in written language. We have shown that the study of emotional processing in language has significant importance for psycholinguistics and affective neuroscience. We proposed that it might be a useful approach to investigate emotional language processing from an embodiment perspective. Future studies could further investigate the functional connectivity of the emotional and language networks.

2.18 SEMANTIC PROCESSING OF EMOTIONAL WORDS IN ADOLESCENTS WITH MOOD DISORDERS: AN EVENT-RELATED POTENTIAL STUDY

Cognitive theories of mood disorders posit that mood-congruent information processing may contribute to symptom maintenance. Although support has been documented in areas of attention, memory, and cognitive control, few studies have examined mood-dependent processes involved in language, particularly, semantic processing of emotional language. This study examined event-related potentials, the N400, elicited by unexpected/incongruous words based on the context where larger amplitude reflects less congruency. Larger N400 amplitudes in response to positive words would predict symptoms of depression, whereas larger N400 amplitudes in response to negative words would predict symptoms of mania.

The way you say it, the way I feel it: emotional word processing in accented speech.

The present study examined whether processing words with affective connotations in a listener's native language may be modulated by accented speech. To address this question, we used the Event Related Potential (ERP) technique and recorded the cerebral activity of Spanish native listeners, who performed a semantic categorization task, while listening to positive, negative and neutral words produced in standard Spanish or in four foreign accents. The behavioral results yielded longer latencies for emotional than for neutral words in both native and foreign-accented speech, with no difference between positive and negative words. The electrophysiological results replicated previous findings from the emotional language literature, with the amplitude of the Late Positive Complex (LPC), associated with emotional language processing, being larger (more positive) for emotional than for neutral words at posterior scalp sites. Interestingly, foreign-accented speech was found to interfere with the processing of positive valence and go along with a negativity bias, possibly suggesting heightened attention to negative words. The manipulation employed in the present study provides an interesting perspective on the effects of accented speech on processing affective-laden information. It shows that higher order semantic processes that involve emotion-related aspects are sensitive to a speaker's accent.

Emotional language processing in autism spectrum disorders: a systematic review.

In his first description of Autism Spectrum Disorders (ASD), Kanner emphasized emotional impairments by characterizing children with ASD as indifferent to other people, self-absorbed, emotionally cold, distanced, and retracted. Thereafter, emotional impairments became regarded as part of the social impairments of ASD, and research mostly focused on understanding how individuals with ASD recognize visual expressions of emotions from faces and body postures. However, it still remains unclear how emotions are processed outside of the visual domain. This systematic review aims to fill this gap by focusing on impairments of emotional language processing in ASD. We systematically searched PubMed for papers published between 1990 and 2013 using standardized search terms. Studies show that people with ASD are able to correctly classify emotional language stimuli as emotionally positive or negative. However, processing of emotional language stimuli in ASD is associated with atypical patterns of attention and memory performance, as well as abnormal physiological and neural activity. Particularly, younger children with ASD have difficulties in acquiring and developing emotional concepts, and avoid using these in discourse. These emotional language impairments were not consistently associated with age, IQ, or level of development of language skills. We discuss how emotional language impairments fit with existing cognitive theories of ASD, such as central coherence, executive dysfunction, and weak Theory of Mind. We conclude that emotional impairments in ASD may be broader than just a mere consequence of social impairments, and should receive more attention in future research.

It's all in your head - how anticipating evaluation affects the processing of emotional trait adjectives.

Language has an intrinsically evaluative and communicative function. Words can serve to describe emotional traits and states in others and communicate evaluations. Using electroencephalography (EEG), we investigate how the cerebral processing of emotional trait adjectives is modulated by their perceived communicative sender in anticipation of an evaluation. 16 students were videotaped while they described themselves. They were told that a stranger would evaluate their personality based on this recording by endorsing trait adjectives. In a control condition a computer program supposedly randomly selected the adjectives. Actually, both conditions were random. A larger parietal N1 was found for adjectives in the supposedly human-generated condition. This indicates that more visual attention is allocated to the presented adjectives when putatively interacting with a human. Between 400 and 700 ms a fronto-central main effect of emotion was found. Positive, and in tendency also negative adjectives, led to a larger late positive potential (LPP) compared to neutral adjectives. A centro-parietal interaction in the LPP-window was due to larger LPP amplitudes for negative compared to neutral adjectives within the ‘human sender’ condition. Larger LPP amplitudes are related to stimulus elaboration and memory consolidation. Participants responded more to emotional content particularly when presented in a meaningful ‘human’ context. This was first observed in the early posterior negativity window (210–260 ms). But the significant interaction between sender and emotion reached only trend-level on post hoc tests. Our results specify differential effects of even implied communicative partners on emotional language processing. They show that anticipating evaluation by a communicative partner alone is sufficient to increase the relevance of particularly emotional adjectives, given a seemingly realistic interactive setting.

Emotional language processing: How mood affects integration processes during discourse comprehension

This research tests whether mood affects semantic processing during discourse comprehension by facilitating integration of information congruent with moods’ valence. Participants in happy, sad, or neutral moods listened to stories with positive or negative endings during EEG recording. N400 peak amplitudes showed mood congruence for happy and sad participants: endings incongruent with participants’ moods demonstrated larger peaks. Happy and neutral moods exhibited larger peaks for negative endings, thus showing a similarity between negativity bias (neutral mood) and mood congruence (happy mood). Mood congruence resulted in differential processing of negative information: happy mood showed larger amplitudes for negative endings than neutral mood, and sad mood showed smaller amplitudes. N400 peaks were also sensitive to whether ending valence was communicated directly or as a result of inference. This effect was moderately modulated by mood. In conclusion, the notion of context for discourse processing should include comprehenders’ affective states preceding language processing.

Cosmetic Use of Botulinum Toxin-A Affects Processing of Emotional Language

How does language reliably evoke emotion, as it does when people read a favorite novel or listen to a skilled orator? Recent evidence suggests that comprehension involves a mental simulation of sentence content that calls on the same neural systems used in literal action, perception, and emotion. In this study, we demonstrated that involuntary facial expression plays a causal role in the processing of emotional language. Subcutaneous injections of botulinum toxin-A (BTX) were used to temporarily paralyze the facial muscle used in frowning. We found that BTX selectively slowed the reading of sentences that described situations that normally require the paralyzed muscle for expressing the emotions evoked by the sentences. This finding demonstrates that peripheral feedback plays a role in language processing, supports facial-feedback theories of emotional cognition, and raises questions about the effects of BTX on cognition and emotional reactivity. We account for the role of facial feedback in language processing by considering neurophysiological mechanisms and reinforcement-learning theory.

Dealing with Feelings: Characterization of Trait Alexithymia on Emotion Regulation Strategies and Cognitive-Emotional Processing

BackgroundAlexithymia, or “no words for feelings”, is a personality trait which is associated with difficulties in emotion recognition and regulation. It is unknown whether this deficit is due primarily to regulation, perception, or mentalizing of emotions. In order to shed light on the core deficit, we tested our subjects on a wide range of emotional tasks. We expected the high alexithymics to underperform on all tasks.MethodTwo groups of healthy individuals, high and low scoring on the cognitive component of the Bermond-Vorst Alexithymia Questionnaire, completed questionnaires of emotion regulation and performed several emotion processing tasks including a micro expression recognition task, recognition of emotional prosody and semantics in spoken sentences, an emotional and identity learning task and a conflicting beliefs and emotions task (emotional mentalizing).ResultsThe two groups differed on the Emotion Regulation Questionnaire, Berkeley Expressivity Questionnaire and Empathy Quotient. Specifically, the Emotion Regulation Quotient showed that alexithymic individuals used more suppressive and less reappraisal strategies. On the behavioral tasks, as expected, alexithymics performed worse on recognition of micro expressions and emotional mentalizing. Surprisingly, groups did not differ on tasks of emotional semantics and prosody and associative emotional-learning.ConclusionIndividuals scoring high on the cognitive component of alexithymia are more prone to suppressive emotion regulation strategies rather than reappraisal strategies. Regarding emotional information processing, alexithymia is associated with reduced performance on measures of early processing as well as higher order mentalizing. However, difficulties in the processing of emotional language were not a core deficit in our alexithymic group.
