For better or for worse: differential effects of the emotional valence of words on children’s recall

ABSTRACT Recent research has revealed the widespread effects of emotion on cognitive functions and memory. However, the influence of emotional valence on verbal short-term memory remains largely unexplored, especially in children. This study measured the effect of emotional valence on word immediate serial recall in 4–6-year-old French children (N = 124). Results show a robust effect of emotional valence on recall performances and recall errors. More precisely, we observed a facilitating effect of the positive valence of words: it allows better performance and causes few recall errors. On the contrary, the data indicated a disruptive impact of negative word valence: the latter causes very low recall performance and is associated with a high proportion of recall errors. These findings add new evidence of the influence of emotion on children’s verbal short-term memory. Our results are discussed in relation to current semantic and attentional explanations of the emotional enhancement of memory.

Emotional words evoke region- and valence-specific patterns of concurrent neuromodulator release in human thalamus and cortex.

Words represent a uniquely human information channel-humans use words to express thoughts and feelings and to assign emotional valence to experience. Work from model organisms suggests that valence assignments are carried out in part by the neuromodulators dopamine, serotonin, and norepinephrine. Here, we ask whether valence signaling by these neuromodulators extends to word semantics in humans by measuring sub-second neuromodulator dynamics in the thalamus (N= 13) and anterior cingulate cortex (N= 6) of individuals evaluating positive, negative, and neutrally valenced words. Our combined results suggest that valenced words modulate neuromodulator release in both the thalamus and cortex, but with region- and valence-specific response patterns, as well as hemispheric dependence for dopamine release in the anterior cingulate. Overall, these experiments provide evidence that neuromodulator-dependent valence signaling extends to word semantics in humans, but not in a simple one-valence-per-transmitter fashion.

Learning new words via reading: The influence of emotional narrative context on learning novel adjectives.

People learn new words in narrative contexts, but little is known about how the emotional valence of the narrative influences word learning. In a pre-registered experiment, 76 English-speaking adults read 30 novel adjectives embedded in 60 short narratives (20 positive, 20 negative, and 20 neutral valence). Both immediately after and 24 hr later, participants completed a series of post-tests, including speeded recognition, sentence completion, meaning generation, and valence judgement. Results showed that participants learned both the novel word form and its meaning. Compared with novel words experienced in the neutral contexts, those read in the emotional contexts (both positive and negative) showed better learning of orthographic form in the immediate post-test, but only those read in the negative context were recognised with greater accuracy in the delayed post-test. Furthermore, the valence of the context was reflected in the word meanings participants generated for each novel word, suggesting that word valence can be inferred from the valence of the contexts. Results from sentence completion and valence judgement were mixed, depending on the task demands. These findings are discussed with reference to theories of affective embodiment and the implications for learning abstract words are considered.

Expectation to rewards modulates learning emotional words: Evidence from a hierarchical Bayesian model.

In language acquisition, individuals learn the emotional value of words through external feedback. Previous studies have used emotional words as experimental materials to explore the cognitive mechanisms underlying emotional language processing, but have failed to recognize that languages are acquired in changing environments. To this end, this study aims to combine reinforcement learning with emotional word learning, using a probabilistic reversal learning task to explore how individuals acquire the valence of emotional words in a dynamically changing environment. Computational modeling on both behavioral and event-related potential (ERP) data revealed that individuals' expectations to rewards modulated the learning speed and temporal processing of emotional words, demonstrating a clear negative bias. Specifically, as the expected value increased, individuals responded faster and exhibited higher amplitudes for negative emotional words. These findings shed light on the neural mechanisms of emotional word learning in a volatile environment, highlighting the crucial role of expectations in this process and a preference for learning negative information.

Word learning in the wild: App-based evidence for valence and concreteness effects

AbstractSecond language (L2) learners need to acquire large vocabularies to approach native-like proficiency. Many controlled experiments have investigated the factors facilitating and hindering word learning; however, few studies have validated these findings in real-world learning scenarios. We use data from the language learning app Lingvist to explore how L2 word learning is affected by valence (positivity/negativity) and concreteness of target words and their linguistic contexts. We found that valence, but not concreteness, affects learning. Users learned positive and negative words better than neutral ones. Moreover, positive words are learned best in positive contexts and negative words in more negative contexts. Word and context valence effects are strongest on the learner’s second encounter with the target word and diminish across subsequent encounters. These findings provide support for theories of embodied cognition and the lexical quality hypothesis and point to the linguistic factors that make learning words, and by extension languages, faster.

Emotional valence promotes free recall of foreign language words after video exposure

AbstractThe effect of emotional valence in word retrieval is well‐established in native languages, but findings in a foreign language remain inconsistent. This study investigated the impact of emotional valence on free word recall in English as a foreign language after video exposure. Participants were upper‐intermediate English speakers with Spanish as their mother tongue who watched eight emotionally valenced and four neutral videos, followed by an immediate free recall task and a delayed recall task after 2 weeks. Generalized linear mixed models showed that word valence influenced recall, with neutral words being less easily recalled than negative words, and a decline in recall between sessions. These findings support the Motivated Attention Account, which suggests that motivationally significant stimuli capture more attention than neutral stimuli, regardless of their polarity. Furthermore, the results align with previous evidence in native language research and some studies in foreign language contexts. This study highlights the robust effect of emotional valence on word recall at different time intervals, using authentic input with upper‐intermediate English speakers who have Spanish as their mother tongue and who learned English later in life.

Independent Effects of Emotional Expression and Group Membership in the Evaluative Priming Task.

Research on automatic evaluative responses to faces varying in emotional expression and ethnicity has yielded conflicting results. Some paradigms, like the Approach/Avoidance task, demonstrated interactive evaluation. In contrast, recent studies using the Evaluative Priming Task (EPT) yielded independent effects of expression and ethnicity. One key difference between these paradigms is the task relevance of the faces. In the EPT faces served solely as primes without direct relevance to the task. To examine whether increased task relevance could engender interactive processing in the EPT, we utilized a modified version of the "bona fide pipeline" EPT. In this adaptation, participants categorized the valence of target words succeeding prime faces followed by probe faces. Participants then judged whether the prime and probe faces depicted the same person, thereby adding task relevance to the prime faces. Experiment 1 revealed independent priming effects of emotion and ethnicity. Since error data and inverse efficiency scores provided evidence for an interactive evaluation, we replicated Experiment 1 using a sequential Bayes testing strategy. Experiment 2 confirmed that the effects of emotion and ethnicity remain independent, indicating that increased task relevance did not yield the integrated processing of emotion and ethnicity as initially hypothesized.

Clouded judgments? The role of virtual weather in word valence evaluations

ABSTRACT Exploring the dynamic interface of environmental psychology and psycholinguistics, this investigation delves into how simulated weather conditions – sunny versus rainy – affect emotional perceptions of linguistic stimuli within a Virtual Reality (VR) framework. Participants assessed words’ emotional valence being exposed to these distinct environmental simulations. Contrary to expectations, we found that while rainy conditions modestly prolonged response times, they did not significantly alter the emotional valence attributed to words. Our study shows that weather can affect emotional cognition, but intrinsic emotional word properties are resilient to environmental influences. This highlights the complex interplay between environmental factors and linguistic processing and reaffirms the importance of environmental contexts in cognitive and emotional evaluations, especially in the face of climate change. By integrating VR technology with environmental psychology and linguistics, our research offers novel insights into the subtle yet significant ways in which virtual and real-world environments converge to shape human emotional and cognitive responses.

Statistical Relationships Between Phonological Form, Emotional Valence and Arousal of Spanish Words.

A number of studies have provided evidence of limited non-arbitrary associations between the phonological forms and meanings of affective words, a finding referred to as affective sound symbolism. Here, we explored whether the affective connotations of Spanish words might have more extensive statistical relationships with phonological/phonetic features, or affective form typicality. After eliminating words with poor affective rating agreement and morphophonological redundancies (e.g., negating prefixes), we found evidence of significant form typicality for emotional valence, emotionality, and arousal in a large sample of monosyllabic and polysyllabic words. These affective form-meaning mappings remained significant even when controlling for a range of lexico-semantic variables. We show that affective variables and their corresponding form typicality measures are able to significantly predict lexical decision performance using a megastudy dataset. Overall, our findings provide new evidence that affective form typicality is a statistical property of the Spanish lexicon.

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.

The Effects of Problematic Internet Use and Emotional Connotation on Internet Slang Processing: Evidence from a Lexical Decision Task.

Young people use slang for identifying themselves with a particular social group, gaining social recognition and respect from that group, and expressing their emotional state. One feature of Internet slang is its active use by youth in online communication, which, under certain conditions, may cause problematic Internet use (PIU). We conducted two studies in young Russian speakers (n1 = 115, n2 = 106). In study 1, participants were asked to rate a set of slang and common words using Self-Assessment Manikin. The study revealed that the most reliable predictor of higher emotional ratings was word familiarity. There were no significant effects of slang vs. common words or word frequency. In study 2, we used a dual lexical decision task to reveal the effects of word characteristics and propensity for PIU on reaction time (RT) for Internet slang words in pairs with semantically related vs. unrelated common words. Study 2 did not reveal any significant semantic priming effect. Word frequency was a significant predictor of lexical decision facilitation. Common, but not slang, word valence and dominance significantly affected RT in the opposite direction. Individuals with higher cognitive preoccupation with the Internet responded significantly faster, while those more likely to use online communication for mood regulation responded significantly slower to the stimuli. Apparently, on explicit and implicit levels, in-depth knowledge of Internet slang can be one the PIU markers. The results are discussed in line with Davis' approach to determining the general pathological Internet use.

Assessment of phonological awareness: Effects of emotional words on preschoolers’ skills

Phonological awareness is recognized as a precursor to reading success. Choosing material to assess children’s phonological awareness is a major challenge. The literature highlights factors that can influence children’s phonological skills, such as the frequency of words, their lexical status, and their linguistic parameters. To date, no study has looked at the potential effect of the emotional parameters of words on phonological skills. The emotional polarity of words (valence: pleasant, unpleasant) has effects on cognitive skills related to phonological awareness, i.e., executive functions, and working memory. The aim of this research is to measure the influence of emotional (positive, negative) and non-emotional (neutral, nonwords) words on the phonological awareness of children aged 4–6 years. Our results show a differential effect of emotional valence words on phonological skills. More specifically, the emotional valence of words facilitates the performance of epiphonological tasks, whereas negative valence disrupts the performance of metaphonological tasks. These results are discussed in relation to current models of interaction between emotion and cognition.

War feels less horrid in a foreign accent: exploring the impact of the foreign accent on emotionality

IntroductionThe processing of a foreign accent is known to increase cognitive load for the native listener, establish psychological distance with the foreign-accented speaker, and even influence decision-making. Similarly, research in the field of emotional processing indicates that a foreign accent may impact the native listener's emotionality. Taking these aspects into consideration, the current study aimed to confirm the hypothesis that a foreign accent, compared to a native accent, significantly affects the processing of affective-laden words.MethodsIn order to test this hypothesis, native Spanish speakers participated in an online experiment in which they rated on a Likert scale the valence and arousal of positive, neutral and negative words presented in native and foreign accents.ResultsResults confirm a foreign accent effect on emotional processing whereby positively valenced words are perceived as less positive and negatively valenced words as less negative when processed in a foreign accent compared to a native accent. Moreover, the arousal provoked by emotion words is lesser when words are processed in a foreign than a native accent.DiscussionWe propose possible, not mutually exclusive, explanations for the effect based on linguistic fluency, language attitudes and the linguistic context of language acquisition. Although further research is needed to confirm them, these explanations may be relevant for models of language comprehension and language learning. The observation of a reduction in emotionality resulting from a foreign accent is important for society as important decisions are made by representatives with diverse language and accent backgrounds. Our findings demonstrate that the choice of the language, which entails speaking in a native or a foreign accent, can be crucial when discussing topics such as the consequences of wars, pandemics, or natural disasters on human beings.

Diachronic predictor of affective ratings of English words

This work considers implementation of a diachronic predictor of valence, arousal and dominance ratings of English words. The estimation of affective ratings is based on data on word co-occurrence statistics in the large diachronic Google Books Ngram corpus. Affective ratings from the NRC VAD dictionary are used as target values for training. When tested on synchronic data, the obtained Pearson‘s correlation coefficients between human affective ratings and their machine ratings are 0.843, 0.779 and 0.792 for valence, aroused and dominance, respectively. We also provide a detailed analysis of the accuracy of the predictor on diachronic data. The main result of the work is creation of a diachronic affective dictionary of English words. Several examples are considered that illustrate jumps in the time series of affective ratings when a word gains a new meaning. This indicates that changes in affective ratings can serve as markers of lexical-semantic changes.

Exploring the role of executive functions in Chinese-English bilinguals’ emotional word comprehension during language switching

ABSTRACT Switching between languages requires the participation of executive functions (EFs) which comprise both the ‘hot’ affective aspects (hot EFs) and the ‘cool’ cognitive aspects (cool EFs). However, the role of these EFs in language switching is not clear. This study employed a word valence categorization task to explore the effects of hot (i.e. emotional valence and emotional congruency) and cool (i.e. inhibitory control ability, IC ability) EFs on high- and low-IC Chinese-English bilinguals’ language switching costs. The results showed smaller language switching costs for positive than negative emotional words, for emotional incongruent than congruent trials, for positive than negative emotional words in emotional congruent trials and for negative emotional words in emotional incongruent than congruent trials. Moreover, hot and cool EFs worked interactively, with larger language switching costs for negative emotional words and the same pattern in emotional congruent trials for high-IC participants over low-IC ones. These results indicate that various aspects of hot EFs affect language switching costs individually and interactively, while also modulate the effects of cool EF on language switching costs during Chinese-English emotional word comprehension. These findings have implications for extending the Bilingual Interactive Activation plus (BIA+) model by incorporating both hot and cool EFs.

Brain potentials reveal reduced sensitivity to negative content during second language production

Abstract Prior research suggests that bilinguals show reduced sensitivity to negative content when operating in the second language (L2). The available evidence, however, is limited to language comprehension. We tested the production of emotional words in Polish (L1)–English (L2) bilinguals in two EEG studies that manipulated emotional cueing. In Experiment 1 (neutral context), white or black circles indicated whether participants should read aloud (shadow) or translate a subsequently presented word. N400 amplitudes were selectively reduced for negative L2 words regardless of the task. In Experiment 2 (emotional context), we used black or white emojis, either sad or neutral, as cues. The previous interaction between word valence and language of operation vanished, but late positive potential amplitudes elicited by negative words were larger for translation from L2 to L1 (i.e., production in Polish) than L1 to L2. These results validate and extend to production previous findings of attenuated emotional response in L2 comprehension.

Dexamphetamine increased speech and visual unimodal illusions in healthy participants without affecting temporal binding window.

Stimuli received beyond a very short timeframe, known as temporal binding windows (TBWs), are perceived as separate events. In previous audio-visual multisensory integration (McGurk effect) studies, widening of TBWs has been observed in people with schizophrenia. The present study aimed to determine if dexamphetamine could increase TBWs in unimodal auditory and unimodal visual illusions that may have some validity as experimental models for auditory and visual hallucinations in psychotic disorders. A double-blind, placebo-controlled, counter-balanced crossover design with permuted block randomisation for drug order was followed. Dexamphetamine (0.45mg/kg, PO, q.d.) was administered to healthy participants. Phantom word illusion (speech illusion) and visual-induced flash illusion/VIFI (visual illusion) tests were measured to determine if TBWs were altered as a function of delay between stimuli presentations. Word emotional content for phantom word illusions was also analysed. Dexamphetamine significantly increased the total number of phantom words/speech illusions (p<0.01) for pooled 220-1100ms ISIs in kernel density estimation and the number of positive valence words heard (beta=2.20, 95% CI [1.86, 2.55], t=12.46, p<0.001) with a large effect size (std. beta=1.05, 95% CI [0.89, 1.22]) relative to placebo without affecting the TBWs. For the VIFI test, kernel density estimation for pooled 0-801ms ISIs showed a significant difference (p<0.01) in the data distributions of number of target flash (es) perceived by participants after receiving dexamphetamine as compared with placebo. Overall, healthy participants who were administered dexamphetamine (0.45mg/kg, PO, q.d.) experienced increases in auditory and visual illusions in both phantom word illusion and VIFI tests without affecting their TBWs.

What Does It Mean to Be “Utterly Content”? Semantic Prosody Impacts Nuanced Inferences Beyond Just Valence

Words have semantic prosody when they collocate with positive/negative concepts in natural language. Semantic prosody encourages positive/negative evaluations. However, it is unknown whether semantic prosody affects inferences of other attributes aside from positivity/negativity. Semantic prosody likely causes people to expect the valence of what comes next, and expectation violations occur when authors have ironic intent and when authors lack fluency with a language. Four studies investigated whether semantically prosodic expectations impact specific inferences about authors. Participants perceived a writer as having greater ironic intent when the writer used a sentence with a semantically prosodic word that mismatched with the valence of adjacent words (Studies 1, 3, and 4). Additionally, in line with English as foreign language pedagogy, the same manipulation caused participants to perceive a writer as being less fluent in English (Studies 2, 3, and 4). Thus, semantic prosody generates expectations that affect nuanced inferences.
