Verbal, physical and relational aggression: individual differences in emotion and cognitive regulation strategies

Cognitive and emotion regulation strategies play an influential role in the display of aggression, however much of this research has failed to identify specific regulation strategies related to aggression. The study’s objective was to assess how emotional processes and the habitual use of maladaptive cognitive emotion regulation strategies are associated with trait aggression. Participants (N = 306; Mage = 33.79; SD = 13.29), completed a self-report survey battery assessing four subtypes of trait aggression (physical, verbal and romantic relational and peer-directed relational), emotion (anger, hostility) and maladaptive cognitive emotion regulation strategies (blaming others, blaming self, ruminating, catastrophizing). Results indicated that anger and hostility (the emotion based variables) had greater influence on all subtypes of trait aggression (physical, verbal, and relational aggression), compared to cognitive emotion regulation strategies which had less of an influence. Blaming others had a positive association with physical and peer directed relational aggression. Low levels of rumination were associated with physical aggression, while low levels of self-blame were associated with peer directed relational aggression. Findings suggest that maladaptive cognitive emotion regulation strategies have differential impact on different forms of aggressive behavior.

Dispositional compassion shifts social preferences in systematic ways.

How people attach value to the outcomes of self and other-social preferences-is central to social behavior. Recently, how dispositional and state emotion shape such social preferences has received researchers' attention. The present investigation asked whether and to what extent dispositional and state compassion predict shifts in social preferences across 4 samples: two correlational samples (final ns 153 & 368, study 1a and 1b) and two experimental samples (final ns: 430 & 530, studies 2 and 3). In keeping with recent accounts of compassion, dispositional compassion predicted general preference for equality, expressed as dispreference for both monetary advantage over another (interaction βs = -0.36, -0.33, -0.25, -0.22; all p < 0.001) and monetary disadvantage relative to others (βs: 0.26, 0.27, 0.28, 0.17; all p < 0.01; positive coefficients imply dispreference). This dispositional effect persisted when controlling for prosociality, positivity, agreeableness, and respectfulness. Furthermore, these dispositional compassion effects were relatively unchanged by experimental emotion inductions in studies 3 and 4. The experimental inductions of state compassion and state pride showed little evidence of systematic effects on social preferences relative to each other or a neutral condition. Discussion focused on individual differences in emotion and social preferences.

New archival digital exhibit.

Innovations in Language, Emotion, and Empathy Research is a digital exhibit which celebrates the forgotten contributions to psychology by Prof. Vincent V. Herr, S. J. (1901-1970) and his colleagues in the mid-20th century. It draws on the substantial unpublished material in the Herr Papers at the Loyola University Chicago Archives and Special Collections. The online exhibition showcases over 40 archival documents, images, and photographs. These are elaborated with detailed text presenting Herr's research achievements and impactful collaborations. During his time at Loyola University Chicago, Herr pursued a range of interrelated projects using innovative assessment approaches to measure linguistic, emotional, and social aspects of healthy and disordered mental states. He was adept in experimental techniques which he applied to questions in psychiatry and social psychology. Herr investigated individual differences in emotionality and empathy through original tasks and instrumental measures. He collaborated with colleagues at Harvard and Yeshiva Universities on the religion and mental health project in the 1950s and 1960s supported by the National Institute of Mental Health and became an advisor to Vatican II in 1965.

Predicting children's internalizing symptoms across development from early emotional reactivity

AbstractCurrent methods of assessing children's emotional reactivity fail to capture individual differences in emotion across contexts that may be meaningfully related to youth psychopathology. We therefore explored the utility of modeling variability in young children's positive and negative emotion across emotionally evocative laboratory tasks to predict later adjustment. At age 3, 409 children completed a battery of laboratory tasks eliciting either positive or negative affect. We used latent difference score (LDS) modeling to predict children's caregiver‐reported internalizing symptoms across ages 3, 5, 8, and 11 from variability in their observer‐rated positive and negative emotion across laboratory tasks. We found that sex moderated the association between both average and variability measures of children's negative emotion at age 3 and trajectories of their anxious‐depressive symptoms across childhood. Measures of emotion variability predicted children's internalizing symptoms above and beyond measures of average emotion. Variability indices also provided unique information about the trajectories of children's symptoms. We discuss implications for the utility of LDS modeling in assessing children's emotional reactivity.

Differences in microglia morphological profiles reflect divergent emotional temperaments: insights from a selective breeding model

Microglia play critical roles in healthy brain development and function, as well as the neuropathology underlying a range of brain diseases. Despite evidence for a role of microglia in affective regulation and mood disorders, little is known regarding how variation in microglia status relates to individual differences in emotionality. Using a selective breeding model, we have generated rat lines with unique temperamental phenotypes that reflect broad emotional traits: bred low responder rats (bLRs) are novelty-averse and model a passive coping style, whereas bred high responder rats (bHRs) are highly exploratory and model an active coping style. To identify a functional role of microglia in these phenotypes, we administered minocycline, an antibiotic with potent microglia inhibiting properties and observed shifts in forced swim, sucrose preference, and social interaction behaviors in bLRs. Using detailed anatomical analyses, we compared hippocampal microglia profiles of bHRs and bLRs and found that although the lines had similar numbers of microglia, selective breeding was associated with a shift in the morphological features of these cells. Specifically, microglia from bLRs were characterized by a hyper-ramified morphology, with longer processes and more complicated branching patterns than microglia from bHRs. This morphology is thought to reflect an early stage of microglia activation and suggests that bLR microglia are in a reactive state even when animals are not overtly challenged. Taken together, our results provide novel evidence linking variation in inborn temperament with differences in the baseline status of microglia and implicate a role for microglia in shaping enduring emotional characteristics.

Longitudinal predictors of depression, anxiety, and alcohol use following COVID-19-related stress.

The COVID-19 pandemic imposed profound effects on health and daily life, with widespread stress exposure and increases in psychiatric symptoms. Despite these challenges, pandemic research provides unique insights into individual differences in emotion and cognition that predict responses to stress, with general implications for understanding stress vulnerability. We examined predictors of responses to COVID-19-related stress in an online sample of 450 emerging adults recruited in May 2020 to complete questionnaires assessing baseline stress and psychiatric symptoms, rumination, cognitive reappraisal use and intolerance of uncertainty. Stress and symptoms were re-assessed 3months later (N=200). Greater pandemic-related stressful events were associated with increases in symptoms of depression, anxiety and alcohol use severity. Additionally, individual differences in emotional and cognitive styles emerged as longitudinal predictors of stress responses. Specifically, greater rumination predicted increased depression. Reduced cognitive reappraisal use interacted with stress to predict increases in alcohol use. An unexpected pattern emerged for intolerance of uncertainty, such that stress was associated with increases in depression for those high in intolerance of uncertainty but increases in alcohol use at relatively low levels of intolerance of uncertainty. These results highlight unique vulnerabilities that predict specific outcomes following stress exposure and offer potential prevention targets.

Similar brains blend emotion in similar ways: Neural representations of individual difference in emotion profiles

Our daily emotional experience is a complex construct that usually involves multiple emotions blended in a context-dependent manner. However, the co-occurring and context-dependent nature of human emotions was understated in previous studies when addressing the individual difference in emotional experiences. The present study proposed a situated and blended ‘profile’ perspective to characterize individualized emotional experiences. Eighty participants watched a series of emotional videos with their EEG recorded, and the individual differences in their emotion profiles were measured as the vector distances between their multidimensional emotion ratings for these video stimuli. This measure was found to be a reliable descriptor of individualized emotional experiences and could efficiently predict classical emotional complexity indices. More importantly, inter-subject representational analyses revealed that similar emotion profiles were associated with similar delta-band activities over the prefrontal and temporo-parietal regions and similar theta-band activities over the frontal regions. Furthermore, left- and right-lateralized temporo-parietal representations were observed for positive and negative emotion profiles, respectively. Our findings demonstrate the potential of taking a ‘profile’ perspective for understanding individual differences in human emotions.

Deriving within-person estimates of delta-beta coupling: A novel measure for identifying individual differences in emotion and neural function in childhood.

Delta-beta coupling is increasingly used to understand early emotional development. However, little is known about the development of the coupling, limiting its utility for identifying normative or aberrant functioning. We used a prospective longitudinal sample (N=122) to compare measures of within-person and between-person coupling between ages 3 and 5, track the developmental trajectory of coupling, identify individual differences in patterns of development, and explore emotion-related predictors and outcomes of discrete developmental patterns. Within-person measures, limited in overall utility, were most useful when (1) statistical approaches produced more homogenous groups within the overall sample (extreme groups or latent classes) or (2) the full developmental course was considered. We found two trajectories of change in frontal coupling and three trajectories of change in parietal coupling. Coupling trajectories were predicted by observed fear and approach/avoidance at age 3. In addition, high levels of frontal coupling at age 3 that declined and then levelled out through age 5 were associated with lower levels of internalizing by age 5. This work provides a foundation for understanding normative change in delta-beta coupling across the preschool years and useful insight for the use of this metric in future work.

Individual predictors of lie acceptability across development

ABSTRACT Deception is a common phenomenon in everyday life, yet some people generally lie more than others and some people consider lying more acceptable than others do. Current knowledge about lie acceptability across development or about the individual differences in emotion or personality which shape it is still in an incipient stage. We aimed to expand this emerging body of knowledge by investigating lie acceptability across three educational stages (primary school, middle school and high school) in a sample of 821 children and adolescents, ages 7 to 18. We also examined several predictors of lie acceptability assessed with the Behavioural Assessment System for Children and Adolescents (BASC): anxiety, sensation seeking, social desirability, attitudes towards school and teachers, and relationships with peers and parents. Lower anxiety and lower sensation seeking predicted middle school children’s reduced lie acceptability. We showed that positive attitudes towards school and teachers predicted lower lie acceptability for primary and middle school children, but were not significant predictors for high school children. For middle school children, better peer relationships also predicted lower lie acceptability. This suggests that various predictors contribute differently to shaping lie acceptability across development, which can prove instrumental in designing age-appropriate interventions to reduce deceptive behaviour.

Designing Story-Centric Games for Player Emotion: A Theoretical Perspective

Narratives are powerful because of their impact on our emotional experiences. Recent years have witnessed significant advances in affective computing and intelligent interaction, presenting a broad range of opportunities for enhancing the design, implementation, and adaptivity of interactive narratives. This paper presents preliminary work examining story-centric games and interactive narratives from the perspective of psychological theories of emotion, with a particular focus on player affect. We examine the sources and duration of player emotion, social facets of emotion, players’ individual differences in emotion, and meta-emotions. Recommendations and future directions for research on player emotion in interactive narratives are discussed.

Emotion in imaginative resistance

ABSTRACT Imaginative resistance refers to cases in which one’s otherwise flexible imaginative capacity is constrained by an unwillingness or inability to imaginatively engage with a given claim. In three studies, we explored which specific imaginative demands engender resistance when imagining morally deviant worlds and whether individual differences in emotion predict the degree of this resistance. In Study 1 (N = 176), participants resisted the notion that harmful actions could be morally acceptable in the world of a narrative regardless of the author’s claims about these actions but did not resist imagining that a perpetrator of harm could believe their actions to be morally acceptable. In Study 2 (N = 167) we replicated the findings of Study 1 and showed that imaginative resistance is greatest among participants who experience more negative affect in response to imagining harm and are lower in either trait anxiety or trait psychopathy. In Study 3 (N = 210) we show that this is the case even when the harms assessed include both low-severity (i.e., emotional harm) and high-severity (i.e., killing) cases. Thus, people’s moral beliefs constrain their ability to imagine hypothetical moral alternatives, although this ability systematically varies on the basis of stable individual differences in emotion.

Modeling heritability of temperamental differences, stress reactivity, and risk for anxiety and depression: Relevance to research domain criteria (RDoC).

Animal models provide important tools to study biological and environmental factors that shape brain function and behavior. These models can be effectively leveraged by drawing on concepts from the National Institute of Mental Health Research Domain Criteria (RDoC) Initiative, which aims to delineate molecular pathways and neural circuits that underpin behavioral anomalies that transcend psychiatric conditions. To study factors that contribute to individual differences in emotionality and stress reactivity, our laboratory utilized Sprague-Dawley rats that were selectively bred for differences in novelty exploration. Selective breeding for low versus high locomotor response to novelty produced rat lines that differ in behavioral domains relevant to anxiety and depression, particularly the RDoC Negative Valence domains, including acute threat, potential threat, and loss. Bred Low Novelty Responder (LR) rats, relative to their High Responder (HR) counterparts, display high levels of behavioral inhibition, conditioned and unconditioned fear, avoidance, passive stress coping, anhedonia, and psychomotor retardation. The HR/LR traits are heritable, emerge in the first weeks of life, and appear to be driven by alterations in the developing amygdala and hippocampus. Epigenomic and transcriptomic profiling in the developing and adult HR/LR brain suggest that DNA methylation and microRNAs, as well as differences in monoaminergic transmission (dopamine and serotonin in particular), contribute to their distinct behavioral phenotypes. This work exemplifies ways that animal models such as the HR/LR rats can be effectively used to study neural and molecular factors driving emotional behavior, which may pave the way toward improved understanding the neurobiological mechanisms involved in emotional disorders.

Examination of developmental pathways from preschool temperament to early adolescent ADHD symptoms through initial responsiveness to reward

To identify sources of phenotypic heterogeneity in attention-deficit/hyperactivity disorder (ADHD) accounting for diversity in developmental/ pathogenic pathways, we examined, in a large sample of youth (N = 354), (a) associations between observed temperamental emotionality at age 3, an electrocortical index (i.e., reward positivity [RewP]) of initial responsiveness to reward at age 9, and ADHD symptoms at age 12, and (b) whether the association between emotionality and ADHD symptoms is mediated by initial responsiveness to reward. Bivariate analyses indicated greater positive emotionality (PE) was associated with enhanced RewP, lower age-9ADHD and lower age-12 inattention (IA). Negative emotionality (NE) was not associated with RewP or ADHD. Mediation analyses revealed the association between PE and hyperactivity/impulsivity (H/I) was mediated by RewP; enhanced RewP was associated with greater H/I. Greater PE was associated with enhanced RewP at a trend level. These effects held accounting for age-9 ADHD, age-12 IA and age-12 oppositional defiant and conduct disorder symptoms. As such, preschool emotionality is associated with adolescent ADHD-H/I symptoms through late childhood initial responsiveness to reward. These relations indicate that individual differences in emotionality and reward responsiveness may be informative for personalizing ADHD interventions.

Mothers' real-time emotion as a function of attachment and proximity to their children.

Building on established links between attachment insecurity and maladaptive emotion regulation, here we examine whether traitlike attachment style predicts individual differences in mothers' emotions in situations with and without their children. Using ecological momentary assessment (EMA), we measured the real-time positive and negative emotions of 145 mothers of young children across a 10-day period, with self-reported attachment and presence of children as predictors of individual differences in emotion. Attachment anxiety was associated with more negative emotion and attachment avoidance was associated with less positive emotion. Associations between avoidance and positive emotion were moderated by the presence of children, whereas associations between both anxiety and avoidance and negative emotion were moderated by the amount of time mothers spent with their children. These findings support the notion that parents' attachment style predicts meaningful individual differences in their real-time emotional experiences. As the first study to explore associations between attachment styles and real-time emotional experiences in mothers of young children, this work has important implications for developing interventions that enhance family well-being.

High emotionality to infant cry: associations with adult attachment, gender, and age

ABSTRACT Caregivers’ sensitive responses to infant cry have long-term consequences for adaptive child development. Although mounting evidence suggests that parents who experience high emotionality to infant cry respond less sensitively to infant cry, there is a dearth of knowledge on potential mechanisms underlying individual differences in emotionality to infant cry. The current study investigates the importance of adult attachment security, gender, and age. 76 non-parents (38 female; 19–30 years old) listened to two episodes of infant cry (15 s; 75 s). Individuals with h⁠igher levels of attachment security reported less anxiety and hostility after the short cry, and less hostility after the long cry. For individuals with higher levels of attachment anxiety, associations were in the opposite direction, and individuals with higher levels of attachment avoidance reported more positive emotions after the long cry. Males and emergent adults reported more hostility after the long cry than females and adults. Results are discussed from an adult attachment, gender, and developmental theoretical framework.

People are better at maintaining positive than negative emotional states.

Determining how people maintain positive and negative emotional states is critical to understanding emotional dynamics, individual differences in emotion, and the instrumental value of emotions. There has been a surge in interest in tasks assessing affective working memory that can examine how people maintain stimulus-independent positive and negative emotional states. In these tasks, people are asked to maintain their emotional state that was induced by an initial stimulus in order to compare that state with the state induced by a subsequent stimulus. It is unclear, however, whether measures of accuracy in this task actually reflect the success of maintaining the initial emotional state. In a series of studies, we introduce an idiographic metric of accuracy that reflects the success of emotional maintenance and use that metric to examine whether people are better at maintaining positive or negative emotional states. We demonstrate that people are generally better at maintaining positive emotional states than they are at maintaining negative emotional states (Studies 1-3). We also show that this effect is not due to decay or to spontaneous interference processes (Studies 2-3), retroactive interference processes (Studies 4-5), or reduced engagement with the initial emotional state (Study 5). Although the mechanism underlying this effect is not yet clear, our results have important implications for understanding emotional maintenance and the possible functions of positive and negative emotions.

Through the eyes of the beholder: Simulated eye-movement experience ("SEE") modulates valence bias in response to emotional ambiguity.

Although some facial expressions provide clear information about people's emotions and intentions (happy, angry), others (surprise) are ambiguous because they can signal both positive (e.g., surprise party) and negative outcomes (e.g., witnessing an accident). Without a clarifying context, surprise is interpreted as positive by some and negative by others, and this valence bias is stable across time. When compared to fearful expressions, which are consistently rated as negative, surprise and fear share similar morphological features (e.g., widened eyes) primarily in the upper part of the face. Recently, we demonstrated that the valence bias was associated with a specific pattern of eye movements (positive bias associated with faster fixation to the lower part of the face). In this follow-up, we identified two participants from our previous study who had the most positive and most negative valence bias. We used their eye movements to create a moving window such that new participants viewed faces through the eyes of one our previous participants (subjects saw only the areas of the face that were directly fixated by the original participants in the exact order they were fixated; i.e., Simulated Eye-movement Experience). The input provided by these windows modulated the valence ratings of surprise, but not fear faces. These findings suggest there are meaningful individual differences in how people process faces, and that these differences impact our emotional perceptions. Furthermore, this study is unique in its approach to examining individual differences in emotion by creating a new methodology adapted from those used primarily in the vision/attention domain.

Dynamic functional connectivity and individual differences in emotions during social stress.

Exposure to acute stress induces multiple emotional responses, each with their own unique temporal dynamics. Dynamic functional connectivity (dFC) measures the temporal variability of network synchrony and captures individual differences in network neurodynamics. This study investigated the relationship between dFC and individual differences in emotions induced by an acute psychosocial stressor. Sixteen healthy adult women underwent fMRI scanning during a social evaluative threat (SET) task, and retrospectively completed questionnaires that assessed individual differences in subjectively experienced positive and negative emotions about stress and stress relief during the task. Group dFC was decomposed with parallel factor analysis (PARAFAC) into 10 components, each with a temporal signature, spatial network of functionally connected regions, and vector of participant loadings that captures individual differences in dFC. Participant loadings of two networks were positively correlated with stress-related emotions, indicating the existence of networks for positive and negative emotions. The emotion-related networks involved the ventromedial prefrontal cortex, cingulate cortex, anterior insula, and amygdala, among other distributed brain regions, and time signatures for these emotion-related networks were uncorrelated. These findings demonstrate that individual differences in stress-induced positive and negative emotions are each uniquely associated with large-scale brain networks, and suggest that dFC is a mechanism that generates individual differences in the emotional components of the stress response.

Genetic predisposition to high anxiety- and depression-like behavior coincides with diminished DNA methylation in the adult rat amygdala

Understanding biological mechanisms that shape vulnerability to emotional dysfunction is critical for elucidating the neurobiology of psychiatric illnesses like anxiety and depression. To elucidate molecular and epigenetic alterations in the brain that contribute to individual differences in emotionality, our laboratory utilized a rodent model of temperamental differences. Rats bred for low response to novelty (Low Responders, LRs) are inhibited in novel situations and display high anxiety, helplessness, and diminished sociability compared to High Novelty Responder (HR) rats. Our current transcriptome profiling experiment identified widespread gene expression differences in the amygdala of adult HR/LR rats; we hypothesize that HR/LR gene expression and downstream behavioral differences stem from distinct epigenetic (specifically DNA methylation) patterning in the HR/LR brain. Although we found similar levels of DNA methyltransferase proteins in the adult HR/LR amygdala, next-generation sequencing analysis of the methylome revealed 793 differentially methylated genomic sites between the groups. Most of the differentially methylated sites were hypermethylated in HR versus LR, so we next tested the hypothesis that enhancing DNA methylation in LRs would improve their anxiety/depression-like phenotype. We found that increasing DNA methylation in LRs (via increased dietary methyl donor content) improved their anxiety-like behavior and decreased their typically high levels of Forced Swim Test (FST) immobility; however, dietary methyl donor depletion exacerbated LRs’ high FST immobility. These data are generally consistent with findings in depressed patients showing that treatment with DNA methylation-promoting agents improves depressive symptoms, and highlight epigenetic mechanisms that may contribute to individual differences in risk for emotional dysfunction.

Parent and Adolescent Agreement for Reports of Life Stressors.

In this article, we investigated the extent and nature of informant discrepancies on parent- and adolescent self-report versions of a checklist measuring youth exposure to life stressors. Specifically, we examined (a) mean-level differences, relative consistency, and consensus for family-level and youth-specific stressors and (b) the utility of parent-youth discrepancies in accounting for variance in youth temperament and psychopathology. Participants were 106 parent-child dyads (47 male, 59 female; 90.6% mothers) aged 13 to 18 years old ( M = 16.01, SD = 1.29). The results revealed evidence for both congruence and divergence in parent and youth reports, particularly with respect to respondents' accounts of youth-specific stressors. Discrepancies for youth-specific stressors were associated with adolescents' negative affectivity, surgency, effortful control, and internalizing problems. Discrepancies for youth stressors may therefore reveal individual differences in emotionality and self-regulation, thus reflecting meaningful variance in adolescents' functioning.
