From heart to mind and back again. A duality of emotion overview on emotion-cognition interactions

Interoceptive training with real-time haptic versus visual heartbeat feedback

The perception of signals from within the body, known as interoception, is increasingly recognized as a prerequisite for physical and mental health. This study is dedicated to the development of effective technological approaches for enhancing interoceptive abilities. We provide evidence of the effectiveness and practical feasibility of a novel real-time haptic heartbeat supplementation technology combining principles of biofeedback and sensory augmentation. In a randomized controlled study, we applied the developed naturalistic haptic feedback on a group of 30 adults, while another group of 30 adults received more traditional real-time visual heartbeat feedback. A single session of haptic, but not visual heartbeat feedback resulted in increased interoceptive accuracy and confidence, as measured by the heart rate discrimination task, and in a shift of attention toward the body. Participants rated the developed technology as more helpful and pleasant than the visual feedback, thus indicating high user satisfaction. The study highlights the importance of matching sensory characteristics of the feedback provided to the natural bodily prototype. Our work suggests that real-time haptic feedback might be a superior approach for strengthening the mind-body connection in interventions for physical and mental health.

Well-being balance and lived experiences assessment: a valid, comprehensive measure of positive well-being

Introduction

Widely used measures of self-reported subjective well-being and flourishing generally do not directly measure positive experiences that have been demonstrated to improve subjective well-being and flourishing, which could aid in developing personalized interventions to improve individuals' well-being. The present study evaluated the validity of the Well-being Balance and Lived Experience (WBAL) Model and Assessment, a new model of well-being and corresponding assessment instrument that evaluates the self-reported frequency of positive experiences and positive feelings of well-being, balanced across activation and arousal levels.

Methods

A total of 496 evaluable subjects completed the WBAL Assessment, the PERMA+ Profiler (PERMA+) and the Well-Being Assessment Adult 24-item (WBA-24). A confirmatory factor model corresponding to the WBAL construct was created, and internal and external validity of the WBAL Assessment were interrogated.

Results

The confirmatory factor model showed good fit, indicating that each of the model factors are related but distinct and all items load significantly onto their factors. The WBAL Assessment demonstrated high internal consistency (Cronbach's α = 0.95) and internal validity across well-being factors and Feelings (r = 0.96) and Experiences (r = 0.94) domains. The WBAL Assessment demonstrated strong convergent validity in comparison to PERMA+ (r = 0.80) and WBA-24 (r = 0.75), indicating that the WBAL Assessment measures a similar overall concept of well-being and flourishing. Discriminant validity of WBAL factors was demonstrated for an average of 14.3 of 17 comparator domains. The main differences between instruments are WBAL's assessment of positive Experiences, the comparator instruments' inclusion of feelings with negative valence, and WBA-24's inclusion of financial stability.

Discussion

The WBAL Assessment is a reliable and valid instrument to comprehensively measure positive aspects of well-being that evaluates multiple modifiable contributors to individuals' well-being to guide design of personalized assessment and intervention programs to enhance positive well-being.

Affective norms for emotional ambiguity in valence, origin, and activation spaces

We introduce the first tool to measure the emotional ambiguity on three bivariate spaces: valence (dimensions of positivity and negativity); origin (automaticity and reflectiveness); and activation (subjective significance and arousal). Our database consists of 2650 word stimuli, assessed by 1380 participants in total with the usage of Self-Assessment Manikin scales for each dimension. We show that the ambiguity of valence, origin, and activation may be successfully perceived and reported in a behavioral procedure. The study has allowed us to compute characteristics of each word for every emotional dimension, thus providing the category of intensity of ambiguity (low, moderate, or high). We also studied the curvilinear relationships between the dimensions. Possible usage, specifics, and limitations of our database are discussed.

Predictors of Feeling of Threat Caused by COVID-19 Pandemic, the Distinctive Effects of Automatic vs. Reflective Emotions

The worldwide pandemic that started in December 2019 was a cause of a great rise in the feeling of threat in society. A feeling of threat and distress can be influenced by the span of emotions experienced by a person, and as it is rather clear, that the situation of pandemic evokes negative emotions, they can range from fear to depression, to even disgust. In this study, we wanted to verify the influence of the negative emotions of automatic origin, related to the well-being and homeostasis of the organism and the negative emotions of reflective origin, which are related to social constructs, on the feeling of threat caused by the pandemic outbreak. We expected automatic emotions to have a greater influence on the feeling of threat. We used an online questionnaire to measure the intensity of negative emotions and the feeling of threat among Polish participants in the time of the early outbreak of the pandemic (March-April 2020). Regression analyses were used to identify the predictors of the feeling of threat. The results show the distinctive effect of automatic and reflective groups of emotions. While automatic emotions always increased the feeling of threat, the reflective emotions suppressed the distress, especially in the group of middle-aged and elderly participants. As reflective emotions are developing in the process of socialization, the observed results could suggest, that young people do not process the situation of the pandemic in reflective categories, which leaves them more worried about the situation. We suggest, that promoting reflective thinking can be helpful in interventions in the cases of anxiety caused by the pandemic, as well as in social communication regarding the topic of the pandemic.

Effect of Chinese young children's epidemic cognition on their coping behavior: mediating role of emotion

INTRODUCTION

Young children's epidemic awareness and risk prevention about public health emergencies such as the COVID-19 are issues of great importance deserving research.

OBJECTIVE

To explore the effect of young children's epidemic cognition on their coping behavior, and the mediating role of emotion.

METHOD

An online anonymous survey was administrated on 2221 Chinese parents of young children aged three to six during the COVID-19 overwhelming period.

RESULTS

(1) The epidemic cognition (M = 4.17, SD = 0.73), the coping behavior (M = 4.16, SD = 0.65), and the emotion (M = 3.99, SD = 0.81) were at a relatively high level. (2) Young children's epidemic cognition significantly predicted their coping behavior (β = 0.71, t = 45.29, P < 0.001). The positive prediction effect of epidemic cognition on young children's emotion was significant (β = 0.19, t = 8.56, P < 0.001), and emotion had a significant positive predictive effect on young children's coping behavior (β = 0.20, t = 4.89, P < 0.001).

CONCLUSION

Young children's epidemic cognition can significantly predict their coping behavior, and emotion plays a significant mediating role in their relation. It is necessary for practitioners to optimize the contents and methods of epidemic education on young children.

The Role of the Valence, Arousing Properties and Subjective Significance of Subliminally Presented Words in Affective Priming

In the verbal affective priming paradigm, the properties of a subliminally presented stimulus alter the interpretation of neutral target stimulus. In the experiment reported here, we tested the role of four factors (valence, origin, arousing properties and subjective significance) that determine the emotional reactions to words in affective priming. Subliminal masked presentation of words preceded the explicit task, which was assessment of neutral Quick Response code (QR code) stimuli. The QRs were codes for words representing personality traits. The results showed the effect of assimilation (negative words caused a negative interpretation, positive caused a positive interpretation) for words' emotional valence and no effects for origin. Concerning arousal, we found a weak negative trend. In the case of subjective significance, a moderate positive trend was found. These results suggest that affective priming effects are susceptible not only to the valence of priming stimuli but also to activation factors.

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.

Anyone but Me: Unrealistic Optimism, Emotions and Anxiety in the Face of COVID-19 Pandemic

The worldwide COVID-19 pandemic (and its consequences, such as lockdown and public health regimes) was a novel and stressful situation for most of people, and, as such, it significantly affected both cognitive and emotional functioning of individuals. In our study, we explored unrealistic optimism bias (the cognitive error giving people a feeling of invulnerability) and any declared preventive behaviours undertaken in order to minimise the risk of contagion. We also measured twelve specific emotions (differing in valence and origin) and the feeling of the anxiety caused by the coronavirus. The results allowed us to confirm the occurrence of unrealistic optimism bias (being significantly stronger for men than women), which correlated negatively with the declared number of preventive behaviours. Unrealistic optimism was also positively correlated with negative automatic emotions and negatively correlated with positive reflective emotions. We created models accounting for the variance of general anxiety, finding significant predictors for both separate groups of younger and older adults (negative emotions, both automatic and reflective; and preventive behaviours). However, there was an effect of positive emotions (both automatic and reflective) having a protective role from the feeling of general anxiety, which was significant for the older group only. Our findings may be a valuable cue for coping with crisis situations.

The Affect Misattribution in the Interpretation of Ambiguous Stimuli in Terms of Warmth vs. Competence: Behavioral Phenomenon and Its Neural Correlates

Warmth and competence are fundamental dimensions of social cognition. This also applies to the interpretation of ambiguous symbolic stimuli in terms of their relation to warmth or competence. The affective state of an individual may affect the way people interpret the neutral stimuli in the environment. As previous findings have shown, it is possible to alter the perception of neutral social stimuli in terms of warmth vs. competence by eliciting an incidental affect with the use of emotion-laden words. In the current experiment, we expected the valence and origin of an affective state, factors ascribing emotionally laden words, to be able to switch the interpretation of the neutral objects. We have shown in behavioural results that negative valence and reflective origins promote the interpretation of unknown objects in terms of competence rather than warmth. Furthermore, electrophysiological-response-locked analyses revealed differences specific to negative valence while making the decision in the ambiguous task and while executing it. The results of the current experiment show that the usage of warmth and competence in social cognition is susceptible to affective state manipulation. In addition, the results are coherent with the evolutionary perspective on social cognition (valence effects) as well as with predictions of the dual mind model of emotion (origin effects).

Inhibitory control effectiveness can be improved: The role of arousal, subjective significance and origin of words in modified Emotional Stroop Test

The interference control measured in the Emotional Stroop Task is the phenomenon that gives us an insight into mechanisms of emotion-cognition interactions. Especially the role of dimensions of affect can be easily studied with this paradigm. In the current study, we were interested in the role of the complexity of emotional stimuli (origin). We also aimed at searching for activation-like factors that impair (arousal) or improve (subjective significance) the effectiveness of cognitive control. We have used an orthogonal manipulation of all the above dimensions in words. We expected to find the contrastive effects of arousal and subjective significance on reaction times and Event Related Potential’s amplitudes. On a behavioural level, we observed the reduction of reaction times with increasing subjective significance of stimuli and reflective origin. We also found a correlation between subjective significance and reduction of amplitude polarisation in the N450 component associated with cognitive control execution effort. This experiment shows that subjective significance has an improving role for cognitive control effectiveness, even when valence, arousal and origin levels are controlled. This guides us to conclude that external stimuli may drive not only disruption of control but also its improvement.

Arousal, subjective significance and the origin of valence aligned words in the processing of an emotional categorisation task

An emotional categorisation task allows us to study how emotionality is understood and how emotional factors influence decisions. As emotionality is not only the valence but is also composed of activation (arousal and subjective significance) and the type of process needed to produce emotion (origin), we wanted to test the influence of these emotional factors on with a group of stimuli not differing in valence. We predicted that increasing activation levels should lead to increased classification of stimuli as emotional, with a focus on the late processing stages, when explicit word processing occurs, which on the electrophysiological level corresponds to P300, N450 and LPC components. The behavioural results showed that the emotionality of words increased with increasing levels of arousal and subjective significance. Automatically originated words were assessed as more emotional than reflective ones. The amplitude of the N450 component revealed dissociation for subjective significance and origin effects, showing that these two dimensions ascribe distinct properties of emotionality. Finally, the LPC component was susceptible to all affective dimensions used in manipulation. Our study showed that arousal, subjective significance and origin are dimensions of affect that shape the processing of words' emotionality, when the values of valence were aligned among the stimuli.

Interoceptive awareness and beliefs about health and the body as predictors of the intensity of emotions experienced at the beginning of the pandemic

Background

The COVID-19 pandemic is a type of stressful event which might have an impact on psychological state. A prolonged threat of getting a serious, contagious illness is expected to be associated with an increase of negative emotions and, conversely, with a decrease of positive emotions. As the stressor is strongly linked to health and the body, we decided to investigate what types of factors related to body perception and appraisal are associated with different types of reported emotions. The purpose of the study was to verify the associations between three types of variables: interoceptive awareness as described by Mehling and colleagues (2012a, 2018), negative beliefs about health and body, and different types of emotions.

Methodology

A Multidimensional Assessment of Interoceptive Awareness questionnaire was applied to evaluate interoceptive awareness. The declared emotional state was diagnosed with a list of 20 emotions-divided by valence and origin. Additionally, a list of 10 negative beliefs about health and body was used. The study was held in a correlational schema with 299 subjects recruited via the social media platform Facebook who took part in an online survey.

Results

The study revealed that the scales of Self-Regulation and Trusting are primarily associated with negative automatic and reflective emotions and positive automatic emotions. Furthermore, the Self-Regulation, Trusting dimensions of interoceptive awareness predict an intensity of emotions categorised on the basis of valence and origin. In addition, negative beliefs about health and the body provided an adequate explanation of the variance of most of the types of emotions experienced during the pandemic.

Conclusions

Factors related to body perception, such as interoceptive awareness and negative beliefs about health and body provide a significant contribution to explaining emotional state at the beginning of the pandemic.

Electrophysiological correlates of interference control in the modified emotional Stroop task with emotional stimuli differing in valence, arousal, and subjective significance

The role of emotional factors in maintaining cognitive control is one of the most intriguing issues in understanding emotion-cognition interactions. In the current experiment, we assessed the role of emotional factors (valence, arousal, and subjective significance) in perceptual and conceptual inhibition processes. We operationalised both processes with the classical cognitive paradigms, i.e., the flanker task and the emotional Stroop task merged into a single experimental procedure. The procedure was based on the presentation of emotional words displayed in four different font colours flanked by the same emotional word printed with the same or different font colour. We expected to find distinct effects of both types of interference: earlier for perceptual and later for emotional interference. We also predicted an increased arousal level to disturb inhibitory control effectiveness, while increasing the subjective significance level should improve this process. As we used orthogonal manipulations of emotional factors, our study allowed us for the first time to assess interactions within emotional factors and between types of interference. We found on the behavioural level the main effects of flanker congruency as well as effects of emotionality. On the electrophysiological level, we found effects for EPN, P2, and N450 components of ERPs. The exploratory analysis revealed that effects due to perceptual interference appeared earlier than the effects of emotional interference, but they lasted for an extended period of processing, causing perceptual and emotional interference to partially overlap. Finally, in terms of emotional interference, we showed the effect of subjective significance: the reduction of interference cost in N450 for highly subjective significant stimuli. This study is the first one allowing for the investigation of two different types of interference in a single experiment, and provides insight into the role of emotion in cognitive control.

The influence of the physical context and knowledge of artworks on the aesthetic experience of interactive installations

In the current study, the influence of the physical context and the knowledge of artworks on the aesthetic experience of installation art is tested for the first time. We assessed non-experts in the field of art (N = 158) who viewed interactive installations in either the art gallery context or the classroom. Some participants knew both the artworks’ titles and the curator descriptions, some knew only the titles, and some had no contextual information. We tested both the aesthetic emotions and the aesthetic judgments. For the measurement of aesthetic emotions, we used the Self-Assessment Manikin approach including the traditional dimensions of affect and the measurement of recently-proposed dimensions such as origin or subjective significance. The study replicated previous findings that the gallery context enhances the aesthetic experience – both of art appreciation and aesthetic emotions. Moreover, our results showed that the emotions caused by viewing the installation in the gallery had more of an automatic source (metaphorically coming “from the heart”) and were more subjectively significant than aesthetic emotions experienced in the classroom context. Curatorial information increased the understanding and appreciation of the works of installation art, and also caused the aesthetic emotion to be more positive and more intensive; while having knowledge about the titles did not influence the aesthetic experience.

The aesthetic experience of critical art: The effects of the context of an art gallery and the way of providing curatorial information

The aim of our research was to investigate the influence of the situational context of presenting contemporary critical artworks (in an art gallery vs in a laboratory setting) and the way in which one is acquainted with contextual information, i.e. a curatorial description (reading it on one's own vs listening to it vs a lack of curatorial information), on the reception of critical art. All experimental stimuli were exemplars of contemporary art which raise current controversial social and political issues. Non-experts in the field of art were asked to rate their emotional reactions on non-verbal scales and estimate their liking and understanding of the artworks. As predicted, the art gallery context increased both the experience of aesthetic emotions-in terms of valence, arousal, subjective significance, and dominance and aesthetic judgements-in terms of liking. Thus, for critical art (i.e. current artworks which critically address serious, up-to-date issues) the situational context of the gallery increased the aesthetic experience-which is in line with previous studies on the gallery (or museum) effect. Curatorial information increased understanding, so non-experts seem to need interpretative guidance in the reception of critical art. Subjective significance was higher in the reading of curatorial information condition than the listening to curatorial information condition or the control condition (a lack of curatorial information). It seems, therefore, that art non-experts have a better understanding of critical art after being exposed to the curatorial description, but this does not result in an increase in liking and aesthetic emotions. Probably this is because the curatorial description allows one to grasp the difficult, often unpleasant issue addressed by critical art.

Event-Related Potential Correlates of Valence, Arousal, and Subjective Significance in Processing of an Emotional Stroop Task

The present study is the first to measure event-related potentials associated with the processing of the emotional Stroop task (EST) with the use of an orthogonal factorial manipulation for emotional valence, arousal, and subjective significance (the importance of the current experience for goals and plans for the future). The current study aimed to investigate concurrently the role of the three dimensions describing the emotion-laden words for interference control measured in the classical version of the EST paradigm. The results showed that reaction times were affected by the emotional valence of presented words and the interactive effect of valence and arousal. The expected emotional arousal effect was only found in behavioral results for neutrally valenced words. Electrophysiological results showed valence and subjective significance correlated with the amplitude differences in the P2 component. Moreover, the amplitude of the N450 component varied with the level of subjective significance. This study also demonstrated that exploratory event-related potential analysis provides additional information beyond the classical component-based analysis. The obtained results show that cognitive control effects in the EST may be altered by manipulation in the subjective significance dimension.

Can valence and origin of emotional words influence the assessments of ambiguous stimuli in terms of warmth or competence?

People tend to think that emotions influence the way they think in a spectacular way. We wanted to determine whether it is possible to prime the assessments of ambiguous stimuli by presenting emotion-laden words. We did not expect the differences in assessments that depend only on the emotional factors to be particularly large. Participants were presented with words differing in valence and origin of an affective state, but aligned for arousal, concreteness, length and frequency of use. Their first task was to remember a word. While keeping the word in mind, their second task was to guess by intuition whether the symbol was related to certain traits. Participants assessed objects represented by coding symbols on the scales of warmth or competence. We expected positive valence and automatic origin to promote higher ratings in terms of warmth and reflective origin to promote higher ratings in terms of competence. Positive valence appeared to boost assessments in terms of both warmth and competence, while the origin effect was found to be dissociative: automatic origin promoted intensity of warmth assessments and reflective origin intensity of competence assessments. The study showed an existing relation between emotional and social aspects of the mind, and therefore supports the conclusion that both domains may result from dual processes of a more general character.

Electrophysiological and Behavioral Correlates of Valence, Arousal and Subjective Significance in the Lexical Decision Task

The emotional properties of words, such as valence and arousal, influence the way we perceive and process verbal stimuli. Recently, subjective significance was found to be an additional factor describing the activational aspect of emotional reactions, which is vital for the cognitive consequences of emotional stimuli processing. Subjective significance represents the form of mental activation specific to reflective mind processing. The Lexical Decision Task (LDT) is a paradigm allowing the investigation of the involuntary processing of meaning and differentiating this processing from the formal processing of the perceptual features of words. In this study, we wanted to search for the consequences of valence, arousal, and subjective significance for the involuntary processing of verbal stimuli meaning indexed by both behavioral measures (reaction latencies) and electrophysiological measures (Event-Related Potentials: ERPs). We expected subjective significance, as the reflective form of activation, to shorten response latencies in LDT. We also expected subjective significance to modulate the amplitude of the ERP FN400 component, reducing the negative-going deflection of the potential. We expected valence to shape the LPC component amplitude, differentiating between negative and positive valences, since the LPC indexes the meaning processing. Indeed, the results confirmed our expectations and showed that subjective significance is a factor independent from the arousal and valence that shapes the involuntary processing of verbal stimuli, especially the detection of a link between stimulus and meaning indexed by the FN400. Moreover, we found that the LPC amplitude was differentiated by valence level.

Broadening the Perspective on Emotional Contagion and Emotional Mimicry: The Correction Hypothesis

Emotional contagion has long been conceptualized as the automatic transfer of affective states between people, similar to the spread of diseases. New evidence, however, has challenged this view by demonstrating that emotions, contrary to diseases, spread selectively rather than blindly because their transfer is controlled by social factors. Here, we take a closer look at this top-down social control of emotional contagion. We review literature on the moderating role of social factors in emotional contagion and emotional mimicry, a process often considered a basic mechanism of emotional contagion. We argue that top-down social processes controlling emotional mimicry may be explained by the correction hypothesis formulated to account for contrast effects in priming research. We also analyze whether similar corrective processes may be involved in less automatic mechanisms of emotional contagion, such as social appraisal. Finally, we propose that the modulating effects of social factors on emotional contagion and its mechanisms, similar to priming effects, may be interpreted within the framework of dual-process theories.

Arousal and Subjective Significance Shapes Stimuli Interpretation across Warmth Vs. Competence Dimensions

The current study sought to examine the impact of incidental activation defined as arousal and subjective significance, both represented in connotations of verbal materials, on social perception of unknown and thus ambiguous objects, in terms of two basic dimensions of social cognition: warmth and competence. Arousal was expected to promote interpretation of ambiguous stimuli in terms of warmth, while subjective significance in terms of competence. This means that both activation and social perception may be treated as examples dual-mind systems functioning. Sixty participants (30 women) were exposed to two subsequent tasks. The first involved memorizing 135 words (manipulation prepared in a factorial design contrasting 3 levels of arousal and 3 levels of subjective significance), and the second involved guessing the meaning of hexagram stimuli derived from Far East culture. An increasing level of arousal caused participants to interpret stimuli as increasingly related to warmth, while an increasing level of subjective significance led to interpretations more related to competence. This study shows that two distinct types of activation may trigger different interpretations of social stimuli, which means that there is a link between both types of processes. This finding is of great importance for the dual-mind approach, showing that a multitude of dualities indentified thus far may be related one another. Therefore, it is justified to treat them as emanations of more general mental systems.

The N400/FN400 and Lateralized Readiness Potential Neural Correlates of Valence and Origin of Words' Affective Connotations in Ambiguous Task Processing

Recent behavioral studies revealed an interesting phenomenon concerning the influence of affect on the interpretation of ambiguous stimuli. In a paradigm, where the participants' task was to read a word, remember its meaning for a while, and then choose one of two pictorial-alphabet-like graphical signs best representing the word sense, we observed that the decisions involving trials with reflective-originated verbal stimuli were performed significantly longer than decisions concerning other stimuli (i.e., automatic-originated). The origin of an affective reaction is a dimension which allows speaking of an affect as automatic (you feel it in your guts) or reflective (you feel it comes from your mind). The automatic affective reaction represents the immediate and inescapable as opposed to the reflective, i.e., the delayed and controllable affective responses to stimuli. In the current experiment, we investigated the neural correlates of performance in an QR-signs-selection ambiguous task. We found the effects of valence and origin in the N400/FN400 potential by means of a stimuli-locked analysis of the initial part of the task, that is, the remembering of a certain word stimulus in a working memory. The N400/FN400 effects were separated in space on scalp distribution. Reflective originated stimuli elicited more negative FN400 than other conditions, which means that such stimuli indeed are associated with conceptual incongruence or higher affective complexity of meaning, but distinct from purely cognitive concreteness. Moreover, the amplitude of the potential preceding the decision, analyzed in the response-locked way, was shaped by the origin of an affective state but not valence. Trials involving decisions concerning reflective-originated words were characterized by a more negative amplitude than trials involving automatic-originated and control word stimuli. This corresponds to the observed pattern of response latencies, where we found that latencies for reflective stimuli were longer than for automatic originated or control ones. Additionally, this study demonstrates that the proposed new ambiguous paradigm is useful in studies concerning the influence of affect on decisions.

Two Aspects of Activation: Arousal and Subjective Significance - Behavioral and Event-Related Potential Correlates Investigated by Means of a Modified Emotional Stroop Task

The arousal level of words presented in a Stroop task was found to affect their interference on the required naming of the words’ color. Based on a dual-processes approach, we propose that there are two aspects to activation: arousal and subjective significance. Arousal is crucial for automatic processing. Subjective significance is specific to controlled processing. Based on this conceptual model, we predicted that arousal would enhance interference in a Stroop task, as attention would be allocated to the meaning of the inhibited word. High subjective significance should have the opposite effect, i.e., it should enhance the controlled and explicit part of Stroop task processing, which is color naming. We found that response latencies were modulated by the interaction between the arousal and subjective significance levels of words. The longest reaction times were observed for highly arousing words of medium subjective significance level. Arousal shaped event related potentials in the 150–290 ms time range, while effects of subjective significance were found for 50–150, 150–290, and 290–530 ms time ranges.

Valence and Origin of Emotional Words Influence on Subsequent Perception of Ambiguous Stimuli in Terms of Competence Versus Warmth

The aim of this study was to examine whether the valence and origin of emotional words can alter perception of ambiguous objects in terms of warmth versus competence, fundamental dimensions of social cognition. 60 individuals were invited into the study focusing on the limits of intuition. They were asked to try to guess the meaning of Japanese pictorial signs in terms of their warmth versus competence connotations. Before each trial a subsequent memory load task was applied. Participants were supposed to read and remember words creating a factorial manipulation of valence (three levels) and origins (three levels: automatic, neutral and reflective) of affective connotations presenting to them for 500 ms. For positively valenced words, automatic originated ones resulted in perception of ambiguous signs more in terms of warmth, while reflective originated words resulted in perception of signs more in terms of competence. This study shows that social perception of warmth versus competence is susceptible to emotional influence of unrelated stimulation, and thus can be primed by objects in the environment. Warmth may be treated as linked with automatic mind processes, while competence may be treated as associated with the controlled part of the mind. In a broader context, this experiment results support claim that distinct dualities identified in dual-processes theories of mind are related to one another, and in fact they may be emanations of two more general systems of mind.

The Affective Norms for Polish Short Texts (ANPST) Database Properties and Impact of Participants' Population and Sex on Affective Ratings

The Affective Norms for Polish Short Texts (ANPST) dataset (Imbir, 2016d) is a list of 718 affective sentence stimuli with known affective properties with respect to subjectively perceived valence, arousal, dominance, origin, subjective significance, and source. This article examines the reliability of the ANPST and the impact of population type and sex on affective ratings. The ANPST dataset was introduced to provide a recognized method of eliciting affective states with linguistic stimuli more complex than single words and that included contextual information and thus are less ambiguous in interpretation than single word. Analysis of the properties of the ANPST dataset showed that norms collected are reliable in terms of split-half estimation and that the distributions of ratings are similar to those obtained in other affective norms studies. The pattern of correlations was the same as that found in analysis of an affective norms dataset for words based on the same six variables. Female psychology students' valence ratings were also more polarized than those of their female student peers studying other subjects, but arousal ratings were only higher for negative words. Differences also appeared for all other measured dimensions. Women's valence ratings were found to be more polarized and arousal ratings were higher than those made by men, and differences were also present for dominance, origin, and subjective significance. The ANPST is the first Polish language list of sentence stimuli and could easily be adapted for other languages and cultures.

N450 and LPC Event-Related Potential Correlates of an Emotional Stroop Task with Words Differing in Valence and Emotional Origin

Affective meaning of verbal stimuli was found to influence cognitive control as expressed in the Emotional Stroop Task (EST). Behavioral studies have shown that factors such as valence, arousal, and emotional origin of reaction to stimuli associated with words can lead to lengthening of reaction latencies in EST. Moreover, electrophysiological studies have revealed that affective meaning altered amplitude of some components of evoked potentials recorded during EST, and that this alteration correlated with the performance in EST. The emotional origin was defined as processing based on automatic vs. reflective mechanisms, that underlines formation of emotional reactions to words. The aim of the current study was to investigate, within the framework of EST, correlates of processing of words differing in valence and origin levels, but matched in arousal, concreteness, frequency of appearance and length. We found no behavioral differences in response latencies. When controlling for origin, we found no effects of valence. We found the effect of origin on ERP in two time windows: 290–570 and 570–800 ms. The earlier effect can be attributed to cognitive control while the latter is rather the manifestation of explicit processing of words. In each case, reflective originated stimuli evoked more positive amplitudes compared to automatic originated words.

Affective Norms for 4900 Polish Words Reload (ANPW_R): Assessments for Valence, Arousal, Dominance, Origin, Significance, Concreteness, Imageability and, Age of Acquisition

In studies that combine understanding of emotions and language, there is growing demand for good-quality experimental materials. To meet this expectation, a large number of 4905 Polish words was assessed by 400 participants in order to provide a well-established research method for everyone interested in emotional word processing. The Affective Norms for Polish Words Reloaded (ANPW_R) is designed as an extension to the previously introduced the ANPW dataset and provides assessments for eight different affective and psycholinguistic measures of Valence, Arousal, Dominance, Origin, Significance, Concreteness, Imageability, and subjective Age of Acquisition. The ANPW_R is now the largest available dataset of affective words for Polish, including affective scores that have not been measured in any other dataset (concreteness and age of acquisition scales). Additionally, the ANPW_R allows for testing hypotheses concerning dual-mind models of emotion and activation (origin and subjective significance scales). Participants in the current study assessed all 4905 words in the list within 1 week, at their own pace in home sessions, using eight different Self-assessment Manikin (SAM) scales. Each measured dimension was evaluated by 25 women and 25 men. The ANPW_R norms appeared to be reliable in split-half estimation and congruent with previous normative studies in Polish.
