Interrupting Holistic Processing May Improve The Detection Of Deceptive Emotional Facial Expressions, Christopher A. Gunderson

Electronic Theses and Dissertations

Although a growing body of evidence suggests that genuine and deceptive facial expressions differ, previous work is mixed as to whether observers can discern between them. One explanation is that cues to deception on the face are subtle and not readily perceived by observers. I argue that the way people process faces may obscure these cues, making them ‘unseen’ by observers. In the current work, I pit two hypotheses against each other to test whether interrupting holistic processing improves or impairs the ability to identify deceptive emotional expressions. Since people process faces holistically, one region of the face may interfere …

Working Through Lingering Anger Following Interpersonal Grievances: Examining Mechanisms Of Change In Rumination, Reappraisal, And Identification Of Unmet Needs, Michael Arend Strating

Electronic Theses and Dissertations

Many clients present to psychotherapy with lingering feelings of anger, bitterness, or resentment in response to interpersonal grievances. The current project sought to compare the effects of cognitive reappraisal and needs identification interventions on lingering anger while determining whether intervention effects occur through shared or distinct mechanisms of change. Using an experimental, therapy-analogue design, 197 undergraduate participants (Study 1) completed a brief, self-guided online intervention involving either anger rumination (comparison condition), cognitive reappraisal, or needs identification. This design was replicated in a clinical sample of 31 participants (Study 2) who were recruited from local mental health clinics using the same …

Individual Differences And Ecological Validity Of Emotion Regulation In Response To Sadness, Colin M. Bosma

Electronic Theses and Dissertations

The majority of research on emotion regulation processes has been restricted to controlled laboratory settingsthat use experimental paradigms to investigate short-term outcomes (Berking & Wupperman, 2012). A true understanding of emotion regulation requires an unobtrusive, ecologically valid assessment of the construct as it naturally unfolds in the environment. Digital phenotyping, or moment-by-moment quantification of individual-level human behavior using data from smartphone sensors (Torous & Onnela, 2016), is a novel method for evaluating human behavior in naturalistic settings. The present project is the first to implement digital phenotyping in the investigation of emotion regulation.

The central aim of the study was …

Database Of Picture-Based Cognitive Reappraisal Experiments: Analyses Of Trial-Level Factors, Damon Abraham

Electronic Theses and Dissertations

Cognitive reappraisal is widely recognized as an effective emotion regulation strategy for managing negative emotions. In laboratory research, reappraisal has been shown to attenuate self-reported negative affect as well as physiological and neurological markers of emotion and arousal. In these experiments, emotionally evocative images are frequently used to induce negative affect in participants. Depending on the trial condition, participants are instructed to either look and react naturally or to change their experience using reappraisal. Data are typically aggregated within trial condition, and the average difference in reported negative affect between conditions serves as the behavioral measure of reappraisal success. While …

Designing Interactive Virtual Environments With Feedback In Health Applications., Yi Li

Electronic Theses and Dissertations

One of the most important factors to influence user experience in human-computer interaction is the user emotional reaction. Interactive environments including serious games that are responsive to user emotions improve their effectiveness and user satisfactions. Testing and training for user emotional competence is meaningful in healthcare field, which has motivated us to analyze immersive affective games using emotional feedbacks. In this dissertation, a systematic model of designing interactive environment is presented, which consists of three essential modules: affect modeling, affect recognition, and affect control. In order to collect data for analysis and construct these modules, a series of experiments were …

Binocular Rivalry Of Emotional Expressions, Daniel Stephen Lumian

Electronic Theses and Dissertations

A central debate in defining emotional space is whether emotions are organized categorically (e.g., fear, happy, disgust) or continuously (i.e., along the independent dimensions of valence and arousal). Emotional facial expressions are one tool often leveraged in trying to define emotional space. Faces are rich sources of social and emotional information. Faces, like emotions, can be organized in either categorical (e.g., happy, sad) or continuous (e.g., open-closed) ways. Therefore, understanding the relatedness of emotional facial expressions to each other may shed light on the underlying structure of emotions. Binocular rivalry (BR) is a tool which can be leveraged to measure …

Defining A Role For Affect In Decision-Making, Pareezad Cyrus Zarolia

Electronic Theses and Dissertations

Recent theories of decision-making have hinted that affect might be useful during some decision-making processes. I propose a model, the affective evaluation model, which defines the role of affect in decision-making as helpful when affect is decision-relevant and unhelpful when it is not. In three studies, I manipulate the decision-relevance of affect to test this central component of the affective evaluation model. Study 1 demonstrates that emphasizing decision-relevant affective signals facilitates optimal decision-making as compared to emphasizing purely cognitive evaluations. Study 2 tests the hypothesis that creating the expectation that affect is useful can facilitate decision-making. Finally, Study 3 tests …

The Influence Of Emotion On Memory For A Crime, Taylor Langley

Electronic Theses and Dissertations

Researchers have reported errors in recall or recognition of witnessed events, accounting for the most common cause of false convictions of innocent people. Tiwari (2010) indicated that 25% of suspects who were identified in a line-up were actually innocent. Jurors are strongly influenced by eyewitness testimony and this can lead to false convictions. The validity of eyewitness identification is critical in cases in which it is used as evidence. In the current study we examined specific emotion states by inducing fear, surprise, and neutral moods. We hypothesized that participants in the Fear group would be least susceptible to the effects …

Young Adult Children’S Communicative Management Of Emotions About Divorce And Divorce Disclosures: Creating And Applying A New Measure, Jenna Shimkowski

Electronic Theses and Dissertations

Although scholars have examined the impacts of divorce on children, there has been little research focused on how children communicatively manage and make sense of their emotions following the divorce. Theoretically, the communication field is lacking in the knowledge of ways in which children of divorce handle the emotions that can arise in their new family system. This dissertation consists of two studies. Study 1 included identifying the strategies that young adult children report using to manage their emotions regarding parents’ divorce and creating a new measure based on children’s reports of these management strategies. Young adults reported using verbal …

The Role Of Emotional Expression On Person Identity Recognition, Kristen Paris

Electronic Theses and Dissertations

Facial information concerning person identity and emotional expression is vital to human social interaction, and therefore, we find it beneficial to remember the faces we see. Little is known, however, about whether emotional expressions facilitate or inhibit recognition for person identity. The present studies examined the role of emotional expression on person identity recognition by manipulating whether such information was presented at encoding (i.e., initial perception of the actor) or at recognition (i.e., later memory for the actor). In Experiment 1, participants recognized more actors displaying an angry rather than a happy expression, when they initially saw actors display a …

The Influence Of Individual Differences In Emotional Clarity On Sensitivity To Situational Cues, Elizabeth Lauren Foreman

Electronic Theses and Dissertations

The influence of individual differences in emotional clarity on the use of situational cues in decision making was investigated. Accuracy of situational cues was manipulated in the form of ostensible previous ratings given to participants while viewing pleasant, neutral, or unpleasant pictures. Of importance to this study was whether persons low in emotional clarity would rely more on situational cues, regardless of their accuracy, than would persons high in this trait. Personality was assessed using two scales which measure emotional clarity. Self-monitoring was also examined as a possible moderator of any findings. Contrary to predictions, our findings indicated that individuals …

The Influence Of Emotional Stimuli On Cognitive Performance In Relation To Delusion Intensity In Schizophrenia, Diana Orem

Electronic Theses and Dissertations

Previous research has suggested that there are multiple psychological processes underlying delusional thought. While it appears that cognitive biases in certain reasoning and attention processes are related to delusion-proneness, the influence of emotion on these processes is not well understood. The overall objective of this study was to investigate the effect of emotional content on performance on tasks thought to measure attentional bias, preferential recall, and probabilistic reasoning in individuals with schizophrenia and demographically matched controls. In order to account for level of delusion-proneness, participants also completed a multidimensional measure of delusional thought. It was hypothesized that individuals with schizophrenia …

Applying The Appraisal Theory Of Emotionto Human-Agent Interaction, Aaron Pepe

Electronic Theses and Dissertations

Autonomous robots are increasingly being used in everyday life; cleaning our floors, entertaining us and supplementing soldiers in the battlefield. As emotion is a key ingredient in how we interact with others, it is important that our emotional interaction with these new entities be understood. This dissertation proposes using the appraisal theory of emotion (Roseman, Scherer, Schorr, & Johnstone, 2001) to investigate how we understand and evaluate situations involving this new breed of robot. This research involves two studies; in the first study an experimental method was used in which participants interacted with a live dog, a robotic dog or …
