Electrophysiological Studies of Visual Attention and of Emotion Regulation

Electrophysiological methods, such as electroencephalography (EEG) and electrocardiography (ECG), measure biological activity that allow us to infer underlying cognitive processes. In the first study, we use EEG to track feature-based attention (FBA), a form of visual attention that helps one detect objects with a particular color, motion, or orientation. We explore the use of SSVEPs, generated by flicker presented peripherally, to track attention in a visual search task presented centrally. Classification results show that one can track an observer’s attended color, which suggests that these methods may provide a viable means for tracking FBA in a real-time task. In the second study, we use cardiovascular measures to examine influences of the emotion regulation strategy of reappraisal. We examine cooperation and cardiovascular responses in individuals that were defected on by their opponent in the first round of an iterated Prisoner’s Dilemma. We find significant differences between the emotion regulation conditions using the biopsychosocial (BPS) model of challenge and threat, where participants primed with the reappraisal strategy were weakly comparable with a threat state of the BPS model and participants without an emotion regulation were weakly comparable with a challenge state of the BPS model. In the third study, we use EEG to study the chromatic sensitivity of FBA for color during a visual search task. We use SSVEP responses evoked through peripheral flicker to measure the spectral tuning of color detection mechanisms and how attentional selection is affected by distractor color. Our results find smaller responses for the distractor colors and suggest that feature-based attention to a particular color involves chromatic mechanisms that both enhance the response to a target and minimize responses to distractors

Identifying meaningful facial configurations during iterative prisoner’s dilemma games

The contraction and relaxation of facial muscles in humans is widely assumed to fulfil communicative and adaptive functions. However, to date most work has focussed either on individual muscle movements (action units) in isolation or on a small set of configurations commonly assumed to express “basic emotions”. As such, it is as yet unclear what information is communicated between individuals during naturalistic social interactions and how contextual cues influence facial activity occurring in these exchanges. The present study investigated whether consistent patterns of facial action units occur during dyadic iterative prisoners’ dilemma games, and what these patterns of facial activity might mean. Using exploratory and confirmatory factor analyses, we identified three distinct and consistent configurations of facial musculature change across three different datasets. These configurations were associated with specific gameplay outcomes, suggesting that they perform psychologically meaningful context-related functions. The first configuration communicated enjoyment and the second communicated affiliation and appeasement, both indicating cooperative intentions after cooperation or defection respectively. The third configuration communicated disapproval and encouraged social partners not to defect again. Future work should validate the occurrence and functionality of these facial configurations across other kinds of social interaction

Facial regulation during dyadic interaction: interpersonal effects on cooperation

This study investigated interpersonal effects of regulating naturalistic facial signals on cooperation during an iterative Prisoner’s Dilemma (IPD) game. Fifty pairs of participants played ten IPD rounds across a video link then reported on their own and their partner’s expressed emotion and facial regulation in a video-cued recall (VCR) procedure. iMotions software allowed us to auto-code actors’ and partners’ facial activity following the outcome of each round. We used two-level mixed effects logistic regression to assess over-time actor and partner effects of auto-coded facial activity, self-reported facial regulation, and perceptions of the partner’s facial regulation on the actor’s subsequent cooperation. Actors were significantly less likely to cooperate when their partners had defected on the previous round. None of the lagged scores based on auto-coded facial activity were significant predictors of cooperation. However, VCR variables representing partner’s positive regulation of expressions and actor’s perception of partner’s positive regulation both significantly increased the probability of subsequent actor cooperation after controlling for prior defection. These results offer preliminary evidence about interpersonal effects of facial regulation in interactive contexts and illustrate how dynamic dyadic emotional processes can be systematically investigated in controlled settings

Easing the conscience: feeling guilty makes people cooperate in divorce negotiations

Guilt is an emotion commonly experienced in divorce. Although guilt has been shown to increase cooperative negotiation behavior in organizational contexts, this is the first investigation of the role of guilt in divorce negotiations. Using survey data of 457 divorcing individuals, the authors examined how guilt was related to the most relevant negotiation styles, while controlling for the guilt-overlapping emotions shame and regret. Guilt was related to cooperative negotiation behavior (i.e., more yielding and problem-solving behavior, and less forcing behavior). Shame was related to uncooperative negotiation behavior (i.e., more forcing, more avoiding, less problem-solving behavior), whereas regret had no additional explanatory value

Interpersonal Style Predicts Behavioral Heterogeneity During Economic-Exchange Task Gameplay in Individuals With Social Anxiety

Recent evidence suggests that individuals who exhibit socially anxious (SA) symptoms endorse patterns of maladaptive interpersonal behavior that can be parceled into three subtypes based upon interpersonal circumplex theory: friendly-submissive, hostile-submissive, and hostile-dominant. It remains unclear, however, whether these subtypes translate into observable social behavior in laboratory contexts. I used two economic-exchange tasks, the prisoner’s dilemma game (PDG) and the ultimatum game (UG), as models of domains of social behavior to detect interpersonal differences in a sample of college students (N= 88) who endorsed mild-to-severe levels of SA based upon responses to the Liebowitz Social Anxiety Scale Self-Report (LSAS-SR). Using a two-step automatic clustering procedure, the sample was divided into three groups according to their responses on the Inventory of Interpersonal Problems – 32 (IIP-32). Interpersonal profiles were constructed for these groups and two of the three expected subtypes were identified (friendly-submissive and hostile-submissive); however, instead of hostile-dominance, friendly-dominance emerged as a potential subtype. Hierarchical and quantile regressions were conducted to examine whether SA severity and interpersonal subtype predicted cooperation and acceptance rates in the PDG and UG respectively. The data revealed that in the PDG, SA severity significantly predicted an increase in cooperation rate, while the interpersonal subtypes did not have a significant effect. However, when analyses included only those individuals who met a clinical cutoff for severe SA (N = 66), SA severity no longer predicted cooperation rates. But friendly-submissiveness predicted cooperation rates exceeding 65% during gameplay, while friendly-dominance predicted a ceiling cooperation rate of 65%. Hostile-submissiveness did not predict variance in cooperation rate. In the UG, the interpersonal subtypes and SA severity did not significantly predict acceptance rate. These findings build upon a burgeoning literature substantiating links between self-reported interpersonal problems and unique interindividual psychopathological presentations. However, improvements in sample recruitment, the implementation of economic-exchange tasks, and data-analytic methods need to be put into practice before stronger assertions can be made concerning the therapeutic relevance of these games as social decision-making paradigms

Pride and Status: Unpacking Two Divergent Pathways to Cooperation

Cooperation is essential for addressing social dilemma problems, especially in modern society with rapidly growing human populations and changing ecology. The scientific community and policymakers have recognized the potential of emotions to facilitate effective communication of sustainability and large-scale cooperation. However, research has not yet explored which emotions are specifically linked to promoting cultures of cooperation and sustainability. This dissertation focuses on pride and its proposed dual nature in influencing prosocial motivations through status hierarchy. According to a prominent theory, pride consists of authentic pride and hubristic pride, both of which are tied to different types of status attainment, prestige and dominance. The main behavioral experiment in this study involved creating a status hierarchy and using the Ultimatum Game (UG) to test novel hypotheses. It was found that participants were more willing to offer a fair split of money to opponents who displayed a prestigious expression after outperforming them in three cognitive tasks. However, when participants played against a superior opponent who displayed dominance after outperforming them, they were no more likely to offer money compared to a neutral condition without any status differentiation. The results have important implications for the current literature on the relationship between pride and status and its role in promoting cooperation. Additionally, this research has practical applications, but there are several limitations that should be acknowledged. Future directions for further research challenging the two-facet theory of pride/status are discussed. Overall, this dissertation contributes to the understanding of the complex role of pride in cooperation and sheds light on the dynamics of human social interactions and status hierarchies

Social Processes in the Experience and Regulation of Emotions

The quality of our lives can be characterized, in part, by the emotions we experience. Feeling a preponderance of negative emotions is characteristic of a range of psychological and affective disorders. As such, the ability to regulate emotions has been recognized as critical for maintaining mental health. While definitions of emotions abound, they have been primarily conceptualized as intrapersonal responses to one’s environment. Yet, while our social interactions are an inseparable aspect of our emotional lives, relatively little emphasis has been placed in prior research on the social bases of emotional experiences. This dissertation presents three bodies of research that investigate the role of social processes in experiencing and regulating negative emotions. In the first body of research, I present four studies that investigate how empathy, the ability to experience another person’s emotions, is involved in experiencing anxiety. In the second body of research, I transition to investigating the social bases of emotion regulation. Here, I present two multi-phase studies that investigate how social emotion regulation may be best implemented to help others experiencing different kinds of negative emotions. The third body of research investigates the neural bases of social emotion regulation. The results of these studies highlight how social processes are an inherent part of emotional experiences and emotion regulation

Emotions as strategic information: effects of other's emotional expressions on fixed-pie perception, demands, and integrative behavior in negotiation

"Negotiators often fail to reach integrative ('win–win') agreements because they think that their own and other’s preferences are diametrically opposed—the so-called fixed-pie perception. We examined how verbal (Experiment 1) and nonverbal (Experiment 2) emotional expressions may reduce fixed-pie perception and promote integrative behavior. In a two-issue computer-simulated negotiation, participants negotiated with a counterpart emitting one of the following emotional response patterns: (1) anger on both issues, (2) anger on participant's high priority issue and happiness on participant's low-priority issue, (3) happiness on high priority issue and anger on low-priority issue, or (4) happiness on both issues. In both studies, the third pattern reduced fixed-pie perception and increased integrative behavior, whereas the second pattern amplified bias and reduced integrative behavior. Implications for how emotions shape social exchange are discussed." (author's abstract

Defectors cannot be detected during"small talk" with strangers.

To account for the widespread human tendency to cooperate in one-shot social dilemmas, some theorists have proposed that cooperators can be reliably detected based on ethological displays that are difficult to fake. Experimental findings have supported the view that cooperators can be distinguished from defectors based on "thin slices" of behavior, but the relevant cues have remained elusive, and the role of the judge's perspective remains unclear. In this study, we followed triadic conversations among unacquainted same-sex college students with unannounced dyadic one-shot prisoner's dilemmas, and asked participants to guess the PD decisions made toward them and among the other two participants. Two other sets of participants guessed the PD decisions after viewing videotape of the conversations, either with foreknowledge (informed), or without foreknowledge (naïve), of the post-conversation PD. Only naïve video viewers approached better-than-chance prediction accuracy, and they were significantly accurate at predicting the PD decisions of only opposite-sexed conversation participants. Four ethological displays recently proposed to cue defection in one-shot social dilemmas (arms crossed, lean back, hand touch, and face touch) failed to predict either actual defection or guesses of defection by any category of observer. Our results cast doubt on the role of "greenbeard" signals in the evolution of human prosociality, although they suggest that eavesdropping may be more informative about others' cooperative propensities than direct interaction
