Effect of contextual prediction on emotional word processing: an evidence from ERPNR-D-24-00189.

This study examined the effect of context on the prediction of emotional words with varying valences. It investigated the neural mechanisms underlying the processing differences of emotion words with different valences in both predictable and unpredictable contexts. Additionally, it aimed to address the conflicting results regarding the processing time in predictive contexts reported in previous studies. Participants were instructed to carefully read the text that included the specified emotion words. Event-related potentials elicited by emotional words were measured. To ensure that the participants can read the text carefully, 33% of the texts are followed by comprehension problems. After reading the text, the comprehension questions were answered based on the text content. The study revealed that the N400 amplitude elicited by an unpredictable context was greater than that elicited by a predictable context. Additionally, the N400 amplitude triggered by positive emotion words was larger than that triggered by negative emotion words. However, there was no significant difference in late positive component amplitude observed between contextual prediction and emotional word valence. The present study suggests that predictive processing takes place at an intermediate stage of speech processing, approximately 400 ms after stimulus onset. Furthermore, the presence of a predictive context enhances the processing of emotional information. Notably, brain activity is more pronounced during the processing of positive emotional stimuli compared to negative emotional stimuli. Additionally, the facilitative effect of a predictable context diminishes in the advanced phase of Chinese speech comprehension.

Emotion in language: Emotion word type and valence interactively predicted Chinese emotional word processing in emotion categorization task

AbstractThe present study examined the predicted effects of emotion word type and valence on emotional word recognition and explored their influence on emotion effects through an emotion categorization task. The results showed the influence of emotion word type and valence on emotional words recognition. Emotion‐label words exhibited faster response and higher accuracy rates (ACC) than emotion‐laden words, and positive words evoked faster response and lower ACC than negative words. Positive emotion‐label words and negative emotion‐laden words evoked higher ACC than negative emotion‐label words and positive emotion‐laden words. Besides, the findings revealed the modulation of emotion word type and valence on the emotion effects. Emotion‐label words and positive words displayed larger emotion effects than emotion‐laden words and negative words in reaction time, and only emotion‐laden words and positive emotion‐label words showed emotion effects in ACC. These findings endorsed the mediated emotion concept account, density hypothesis, and automatic vigilance hypothesis. Based on the findings, we proposed a valence cognition account to explain the interactive results.

Effect of Physical Exercise on Executive Functions Using the Emotional Stroop Task in Perimenopausal Women: A Pilot Study.

A quasi-experimental pilot study was conducted involving 14 perimenopausal women (Peri-MG) and 13 healthy young women (YG) who completed an EST before and after an aerobic cycling exercise. Mixed-effects models for repeated measures were used to analyze reaction times (RTs) and error rates (ERs) during emotional word processing (positive, negative, and neutral) for both groups. Compared with the YG, the Peri-MG showed significantly shortened RTs for positive and negative emotions (p < 0.05) post-exercise, but not for neutral words. In addition, the Peri-MG exhibited significantly increased ERs for negative words at baseline compared with the YG (p < 0.05), but this difference was not observed during the post-exercise test. The findings suggest that aerobic exercise can enhance executive control performance in perimenopausal women. The Peri-MG exhibited marked behavioral plasticity in the form of reduced bias to salient cues that were significantly more sensitive to alterations due to exercise. This new evidence enhances the understanding of emotional vulnerability and beneficial susceptibility to exercise in perimenopausal women.

An EPR study of the cognitive processes underlying the impact of self-relevant information on emotional word processing

Using the event-related potentials (ERPs) technique, this study successively presented names (in either a supra- or subthreshold manner) and emotional words to examine how self-relevant cue (self-name) affects emotional word processing in word class judgment task (to determine whether an emotional word is a noun or adjective) and valence judgment task (to determine whether an emotional word is positive or negative). At the suprathreshold condition, self-relevant positive words elicited a more significant Early posterior negativity (EPN) than negative words only in the valence judgment task. In contrast, at the subthreshold condition, self-relevant negative words elicited an enhanced Late positive potential (LPP) than positive words only in the word class judgment task. These results indicate that self-relevant cue affects emotional word processing at both suprathreshold and subthreshold conditions; nevertheless, the effect manifests as self-positive bias at the suprathreshold condition and self-negative bias at the subthreshold condition. The experimental task modulates these dynamics.

Effects of social interactions on the neural representation of emotional words in late bilinguals

ABSTRACT This fMRI study explored the relationship between social interactions and neural representations of emotionality in a foreign language (LX). Forty-five late learners of Japanese performed an auditory Japanese lexical decision task involving positive and negative words. The intensity of their social interactions with native Japanese speakers was measured using the Study Abroad Social Interaction Questionnaire. Activity in the left ventral striatum significantly correlated with social interaction intensity for positive words, while the right amygdala showed a significant correlation for negative words. These results indicate neural representations of LX emotional words link with the intensity of social interactions. Furthermore, LX negative words activated the left inferior frontal gyrus more than positive and neutral words, suggesting greater cognitive effort for processing negative words, aligning with a bias in adult social interactions towards more positively-valenced language. Overall, our findings underscore the importance of social interaction experiences in the processing of LX emotional words.

The influence of emotional context on emotional word processing in discourse comprehension: evidence from event-related potential.

This research utilized event-related potential (ERP) recording technology to examine the effect of emotional context on the processing of emotional information in sentences. Three types of emotion-consistent discourse materials (neutral-neutral, positive-positive and negative-negative) were constructed to specifically express neutral, positive and negative emotions, respectively. Each discourse comprised two sentences, with the emotionally significant words embedded at the penultimate position of the second sentence. Participants were asked to read these texts, respond to reading comprehension questions and the ERP amplitude induced by the emotional words was recorded. The results indicated a tripartite interaction in the N400 and Late positive component amplitudes involving emotional context, emotional words and brain hemispheres, observed in both frontal and central brain regions. Notably, there was a significant difference in response to positive words between positive and negative contexts. The findings suggest that emotional context has a substantial effect on the processing of emotional words. Positive words, in comparison to negative ones, are more influenced by emotional context, particularly in the frontal and central regions of the brain.

Emotion effects in second language processing: Evidence from eye movements in natural sentence reading

Abstract There exists insufficient eye-tracking evidence on the differences in emotional word processing between the first language (L1) and second language (L2) readers. This study conducted an eye-tracking experiment to investigate the emotional effects in L2 sentence reading, and to explore the modulation of L2 proficiency and individual emotional states. Adapted from Knickerbocker et al. (2015), the current study recorded eye movements at both early and late processing stages when late Chinese–English bilinguals read emotion-label and neutral target words in natural L2 sentences. Results indicated that L2 readers did not show the facilitation effects of lexical affective connotations during sentence reading, and they even demonstrated processing disadvantages for L2 emotional words. Additionally, the interaction effect between L2 proficiency and emotion was consistently significant for the measure of total reading time in positive words. Measurements of participants’ depressive and anxious states were not robustly correlated with eye movement measures. Our findings supplemented new evidence to existing sparse eye-tracking experiments on L2 emotion processing, and lent support to several theoretical frameworks in the bilingual research field, including the Emotional Contexts of Learning Theory, Lexical Quality Hypothesis and Revised Hierarchical Model.

Dissociating different temporal stages of emotional word processing by feature-based attention

Negative emotional content is prioritized across different stages of information processing as reflected by different components of the event-related potential (ERP). In this preregistered study (N = 40), we investigated how varying the attentional focus allows us to dissociate the involvement of specific ERP components in the processing of negative and neutral words. Participants had to discriminate the orientation of lines overlaid onto the words, the word type (adjective/noun), or the emotional content (negative/neutral). Thus, attention was either not focused on words (distraction task), non-emotional aspects, or the emotional relevance of words. Regardless of the task, there were no significant differences between negative and neutral words for the P1, N1, or P2 components. In contrast, interactions between emotion and task were observed for the early posterior negativity (EPN) and late positive potential (LPP). EPN differences were absent during the distraction task but were present in the other two tasks. LPP emotion differences were found only when attention was directed to the emotional content of words. Our study adds to the evidence that early ERP components do not reliably separate negative and neutral words. However, results show that mid-latency and late stages of emotion processing are separable by different attention tasks. The EPN represents a stage of attentional enhancement of negative words given sufficient attentional resources. Differential activations during the LPP stage are associated with more elaborative processing of the emotional meaning of words.

Beyond Valence and Arousal: The Role of Age of Acquisition in Emotion Word Recognition.

Although the age of acquisition (AoA) effect has been established in numerous studies, how emotion word processing is modulated by AoA, along with affective factors, such as valence and arousal, is not well understood. Hence, the influence of age of acquisition (AoA), valence, and arousal on Chinese emotion word recognition was investigated through two experiments. Experiment 1 (N = 30) adopted a valence judgment task to explore the roles of valence and AoA in emotion word recognition, whereas Experiment 2 (N = 30) used a lexical decision task to examine AoA and arousal effects. A mixed linear effects model was used to examine the fixed effects of AoA, arousal, and valence and random effects of participants and items. The findings provided confirmation of the effects of AoA, valence, and arousal. Notably, AoA and valence had independent influences on emotion word recognition, as evidenced by longer reaction times for later-acquired words and negative words compared to early-acquired words and positive words (all ps < 0.05). On the other hand, AoA and arousal demonstrated interdependent effects on emotion word recognition. Specifically, a larger AoA effect was observed for low-arousing words (all ps < 0.05), whereas the influence of AoA on high-arousing words was insignificant. These results underscored the significance of AoA in processing emotion words and highlighted the interplay between AoA and arousal. Additionally, it is plausible to suggest that the AoA effect was primarily perceptual rather than semantic in nature.

Lateralization of emotion word in the first and second language: Evidence from Turkish-English bilinguals

As interest in cognitive sciences has grown over the years, language representation in the brain has increasingly become the subject of psycholinguistic studies. In contrast to the relatively clear picture in monolingual language processing, there is still much controversy over bilinguals’ processing of their two languages. The goal of this paper is therefore to provide more evidence on the way emotion words are processed and represented in the brain in late bilinguals. The study seeks to answer three questions: 1. Are positive words processed faster than negative and neutral words in both languages of bilinguals? 2. Is there a difference in the speed in which emotion words are processed in the first (L1) and second language (L2) of bilinguals? 3. How are emotion words represented in the bilingual brain? Participants were late Turkish-English bilinguals (N = 57). We used a visual hemi-field paradigm, in which the stimuli were presented either on the right or left of a computer screen. By pressing the designated keys, the participants performed a lexical decision task in which they determined whether the visually presented L1 and L2 words were real words or non-words. The first result showed that positive words are processed faster than negative and neutral words in both languages of bilinguals, providing further support for the differential processing of emotion words. Second, longer response times were found for L2 as compared to L1. Finally, we found bilateral hemispheric representation for both English and Turkish. These results contribute to the psycholinguistic literature by providing evidence from the relatively understudied language pairs such as English and Turkish.

How Do Foreign Language Learners Process L2 Emotion Words in Silent Reading? An Eye-Tracking Study

The current study aimed to examine the processing of emotion words in L2 silent reading. We conducted two experiments in which Arab learners of English as a foreign language (EFL) read short English sentences in which target words were embedded. The participants’ eye movements were recorded and analyzed. The results of Experiment 1, which compared the processing of emotionally positive versus neutral words by 44 participants, did not reveal any significant effect for word type. The results only showed a few instances of significant interactions between word type and word frequency (i.e., positive words were read faster than neutral words only in the case of high-frequency words) and arousal (i.e., positive words were recognized faster than neutral words only when the target words were low in arousal). The results of Experiment 2, which compared the processing of emotionally negative versus neutral words by 43 participants, only established one effect of word type on the skipping rate which was also modulated by length (i.e., negative words were less likely to be skipped, particularly shorter ones). Moreover, arousal interacted with word type (i.e., only the negative words with low arousal were read faster than neutral words in two eye-movement measures).

The role of selective attention in Chinese emotional word processing: evidence from event-related potentials.

This study seeks to explore the interaction between ignored valence and attended valence in the processing of Chinese emotion words. The experimental materials utilized in this study consisted of Chinese emotion words. Participants were instructed to observe the words and press a key when presented with target words. Additionally, the electroencephalographic responses of the participants were recorded during the experiment. The results showed that emotional nontarget words elicited greater amplitude of the N170 in the attend-emotion words block compared to the attend-neutral words block. Negative nontarget words produce greater amplitude of the late posterior positivity compared to positive nontarget words. In addition, emotional nontarget words were influenced by both ignored and attended valence, whereby positive nontarget words resulted in larger amplitude of the N170 component in the attend-negative block compared to the attend-neutral block. The modulation pattern for negative nontarget words was evident on the left hemisphere. The findings suggest that emotional nontarget words received greater attentional resources in the attend-emotion words block during the early stages of processing, compared to the attend-neutral word block. Additionally, during the later stages of processing, negative nontarget words were more likely to be processed than positive nontarget words. Overall, these results provide support for the evaluation space model.

The Relationship Between Personality Traits and the Processing of Emotion Words: Evidence from Eye-Movements in Sentence Reading.

Previous research shows that processing times on emotion words (both negative and positive) are faster than on non-emotional neutral words. In the current study, we explored how personality traits (the Big Five and the trait emotional intelligence factors) may further influence the processing of emotion versus non-emotion words by conducting two experiments where participants silently read sentences while their eye movements were recorded. The results replicated the facilitative emotion effect and showed that those with higher agreeableness scores had stronger emotion effects on positive words and those with higher extraversion scores, higher openness scores, higher agreeableness scores, lower sociability scores, and higher emotionality scores had stronger emotion effects on negative words. Furthermore, some personality traits also led to different ways that readers approach text, for example, through more risky reading strategies.

Differentiated processing of emotional cues in adolescents and young adults with ICD-11 PTSD and complex PTSD after child abuse.

The recent update of the International Classification of Diseases 11th revision (ICD-11) introduced the diagnosis of complex posttraumatic stress disorder (CPTSD) as a distinct entity from posttraumatic stress disorder (PTSD). Because psychophysiological alterations are a core diagnostic feature of PTSD and CPTSD, the aim of the current study was to examine potential distinctive patterns in cortical and cardiac responses to emotional words in adolescent and young adult patients with PTSD and CPTSD. Event-related potentials and heart rate responses were studied in 81 adolescent and young adult participants, of which 17 individuals were diagnosed with ICD-11 PTSD and 32 individuals with CPTSD, each after childhood sexual and/or physical abuse. Thirty-two individuals served as healthy controls. The paradigm consisted of a passive reading task with neutral, positive, physically threatening, and socially threatening words. Differentiated early processing of emotional words was indicated by differences on P1 and left EPN components. Additionally, PTSD and CPTSD patients presented with specific patterns of heart rate responses to emotional words. In CPTSD patients, heart rate reactions to emotional words were more variable than in PTSD patients. These findings provide early evidence of differentiated cortical and cardiac response patterns in adolescent and young adult patients with CPTSD and PTSD, supporting a nosological distinction between PTSD and complex PTSD. However, due to small and unequal sample sizes, findings presented in the current study are preliminary and require future research.

How do word valence and classes influence lexical processing? Evidence from virtual reality emotional contexts.

The current study examines the influence of word class (i.e., noun vs. adjective) and valence (i.e., positive vs. negative vs. neutral) on the processing of emotional words under different virtual reality (VR) emotional contexts. To this end, 115 participants performed a modified affect labeling task after experiencing different VR scenarios. Their galvanic skin responses were also examined to further gauge the different effects of VR contexts. The results demonstrated significant main effect for word valence, indicating more processing of positive words relative to neutral words which are processed more than negative words. The results also demonstrated significant main effect for word class, indicating more processing of nouns in contrast to adjectives. Additionally, the results indicated that both positive and negative VR contexts could stimulate participants to select more positive words though negatively valenced words were processed more under negative VR context relative to positive VR context. However, the amplitude of galvanic skin responses in positive VR was lower than that in negative VR. The results were interpreted in line with the situation-consistency effects, the mood-consistency effects, the specific nature of VR context, and the different features of different word classes in terms of concreteness, imageability, arousal, and valence.

The role of subjective significance, valence and arousal in the explicit processing of emotion-laden words.

Emotional categorisation (deciding whether a word is emotional or not) is a task that employs the explicit analysis of the emotional meaning of words. Therefore, it allows for assessing the role of emotional factors, i.e., valence, arousal, and subjective significance, in emotional word processing. The aim of the current experiment was to investigate the role of subjective significance, a reflective form of activation that is similar to arousal (the automatic form), in the processing of emotional meaning. We applied the orthogonal manipulation of three emotional factors. Thus, we were able to precisely differentiate the effects of each factor and search for interactions between them. We expected valence to shape the late positive complex LPC component, while subjective significance and arousal were expected to shape the P300 and N400 components. We observed the effects of subjective significance throughout the whole span of processing, while the arousal effect was present only in the LPC component. We also observed that amplitudes for N400 and LPC discriminated negative from positive valence. The results showed that all factors included in the analysis should be taken into account while explaining the processing of emotion-laden words; especially interesting is the subjective significance, which was shown to shape processing individually, as well as to come into interaction with valence and arousal.

Early, emotional and embodied? Processing of emotional words and body words in the native and a second language – evidence from early event-related brain potential modulation and rapid serial visual presentation

ABSTRACT Visual processing of emotional words modulates early event-related potentials (ERPs) such as the early posterior negativity (EPN). Questions remain as to whether this modulation reflects modality-specific processing, preferentially elicited by emotional words of the native language (L1). This study investigates the modulation of early ERPs during rapid serial visual presentation (RSVP) of adjectives or nouns referring to emotional feeling states, neutral traits, to an overweight or lean body or to concrete body parts or neutral objects, presented in the L1 and the second language (L2). Word ratings in the L2 were assessed in a pilot study. The N100 and the EPN were modulated by the emotional valence of the stimuli irrespective of the word class or the task (silent reading vs. word counting). The results suggest that early affective appraisal is obligatory, not restricted to privileged categories of linguistic information (emotions) or solely found for the embodied language (L1).

Can adult learners sense L2 emotional words automatically? The role of L2 use on the emotional Stroop effect

The present study investigated whether adult learners of second language (L2) can automatically activate emotional connotation during emotional word recognition as compared native (L1) users and whether L2 use plays a significant role in it. The automaticity of activation was measured through the emotional Stroop task. In this task, emotional words and neutral words were displayed in two different colors, and the participants were asked to indicate the color by button press. Results showed a delay in L2 learners’ response to emotional words (the emotional Stroop effect) without significant differences from L1 users’ response, indicating comparable automaticity in activating emotional connotation in performing the task. Further analyses on the effect of L2 use revealed its significant role in increasing the emotional Stroop effect. Specifically, L2 learners with higher amount of L2 use in daily life produced a significant emotion Stroop effect comparable to L1 users, while L2 learners with lower L2 use did not. We discuss the importance of L2 use in actual context in automatic processing of L2 emotional words, especially among adult learners who began L2 learning in adulthood in a case of underrepresented languages as L2.

Emotional violation of faces, emojis, and words: Evidence from N400

Human social interactions depend on the construction of emotional meaning. The present study used event-related potentials to investigate the neural features of emotional violation processing in facial expressions, emojis, and emotion words. Behavioral results showed emotion congruency effects among facial expressions, emojis, and emotion words. Emotional violations resulted in a longer response time than emotion congruent conditions in happy context conditions. Responses to angry faces were slower in angry sentences than in happy sentences. As expected, the classic N400 effect was obtained for the emotional violations among facial expressions, emojis, and emotion words. Emotional violations resulted in more negative-going N400 amplitudes. Moreover, the N400 effects elicited by facial expressions and emojis were significantly smaller than emotion words, and there were no significant differences in N400 effects between facial expressions and emojis. The findings suggest that the emotional violation processing of facial expressions, emojis, and emotion words could be reflected in an electrophysiological index of semantic processing, and that emotional violation elicited higher levels of semantic retrieval. In addition, there were differences between nonverbal and verbal information processing in emotional violation, while the emotional violation of words induced greater semantic retrieval demands than facial expressions and emojis.

Feeling Blue and Getting Red: An Exploratory Study on the Effect of Color in the Processing of Emotion Information.

Specific emotions and colors are associated. The current study tested whether the interference of colors with affective processing occurs solely in the semantic stage or extends to a more complex stage like the lexical processing of emotional words. We performed two experiments to determine the effect of colors on affective processing. In Experiment 1, participants completed a color-emotion priming task. The priming stimulus included a color-tinted (blue, red, and gray) image of a neutral face, followed by a target stimulus of gray-scaled emotional (angry and sad) and neutral faces after 50 ms. Experiment 2 used a modified emostroop paradigm and superimposed emotion words on the center of the color-tinted emotional and neutral faces. Results showed the priming effect of red for the angry face compared to the control, but not in blue for the sad face compared to the control. However, responses to the blue-sad pair were significantly faster than the red-sad pair. In the color-emostroop task, we observed a significant interaction between color and emotion target words in the modified emostroop task. Participants detected sad targets more accurately and faster in blue than red, but only in the incongruent condition. The results indicate that the influence of color in the processing of emotional information exists at the semantic level but found no evidence supporting the lexical level effect.
