Show moreArti?cial social intelligence is a step towards human-like human-computer interaction. One important milestone towards building socially intelligent systems is enabling computers with the ability to process and interpret the social signals of humans in the real world. Social signals include a wide range of emotional responses from a simple smile to expressions of complex affects.This dissertation revolves around computational models for social signal processing in the wild, using multimodal signals with an emphasis on the visual modality. We primarily focus on complex affect recognition with a strong interest in curiosity. In this dissertation,we ?rst present our collected dataset, EmoReact. We provide detailed multimodal behavior analysis across audio-visual signals and present unimodal and multimodal classi?cation models for affect recognition. Second, we present a deep multimodal fusion algorithm to fuse information from visual, acoustic and verbal channels to achieve a uni?ed classi?cation result. Third, we present a novel system to synthesize, recognize and localize facial occlusions. The proposed framework is based on a three-stage process: 1) Synthesis of naturalistic occluded faces, which include hand over face occlusions as well as other common occlusions such as hair bangs, scarf, hat, etc. 2) Recognition of occluded faces and differentiating between hand over face and other types of facial occlusions. 3) Localization of facial occlusions and identifying the occluded facial regions. Region of facial occlusion, plays an importantroleinrecognizingaffectandashiftinlocationcanresultinaverydifferentinterpretation, e.g., hand over chin can indicate contemplation, while hand over eyes may show frustration or sadness. Finally, we show the importance of considering facial occlusion type and region in affect recognition through achieving promising results in our experiments.

Title: Taxonomy of Affective Curriculum for Gifted Learners.
Creator: Cavilla, Derek, Eriksson, Gillian, Hynes, Mike, Hopp, Carolyn, Vitale, Thomas, University of Central Florida
Abstract / Description: Teaching and learning in the current milieu of standards-based accountability has resulted in a near-exclusive focus on academic growth and development for students in today's schools. This is particularly acute for gifted students, whose label inherently focuses on superior intellectual capacity and aptitude for academic success.

Show moreTeaching and learning in the current milieu of standards-based accountability has resulted in a near-exclusive focus on academic growth and development for students in today's schools. This is particularly acute for gifted students, whose label inherently focuses on superior intellectual capacity and aptitude for academic success. However, there is a growing demand for equal support of social-emotional learning (SEL) across the globe. In the United States, the Collaborative for Academic, Social, and Emotional Learning (CASEL) has shed significant light on the power of affective development for school-aged children, indicating that, without it, students are limited in their ability to reach their full potential. The proposed Taxonomy of Affective Curriculum for Gifted Learners is intended to provide a framework to reduce the disparity in focus between cognitive and social-emotional development for a population that requires affective support in response to the effects of asynchronous development as well as an inherent proclivity for heightened capacity for emotional intelligence and moral development. Through the research-based definition and sequence of specific affective constructs, the taxonomy leads gifted learners toward their full potential through the eventual development of specific social-emotional abilities, such as harmonious passion (Vallerand et. al, 2003), acceptance of ambiguity (Urban, 2014), willingness to view failure as opportunity for growth (Dweck, 2006), and an increased ability to set and attain meaningful goals (Dweck, 1986). Qualitative data from both practitioners and experts as well as suggested implementation and evaluation of a pilot study further inform the framework's development with implications surrounding the stimulation of greater levels of internal locus of control as well as a clarification of the role of teacher versus counselor of the gifted.

Show moreEmoticons have been shown to be the nonverbal cues of computer-mediated communication and could therefore be a rich source of information, but they are not used in the workplace because they are considered unprofessional. This study aimed to look at the effects of emoticons on relationships, specifically between a leader and member. Participants were asked to read a fake email from a fake boss and answer several questions in regard to leader-member exchange, affective presence, perceived message positivity, perceived masculinity/femininity of the fake boss, and perceived professionalism. This study found that the use of a positive emoticon in an email message increased leader-member exchange, mediated by positive affective presence (though the use of the emoticon and positive affective presence were not linked). This study also found that when participants received a message with an emoticon, they found the sender to be both more feminine and less professional.

Show moreThe affective revolution in the organizational sciences has yielded a body of theoretical and empirical research examining the relationship between affect and performance. This work has typically advanced affect as a predictor of performance; however, more recent theory suggests that the relationship between affect and performance is reciprocal. Since little empirical work exists supporting reciprocity between affect and performance, the purpose of this dissertation is to test if affect and performance are actually reciprocally related. Importantly, the advent of longitudinal and experiential research designs in the organizational sciences affords empirical opportunities to test such theory. This dissertation examines the temporal patterning of relations between affect and performance using longitudinal meta-analysis. Using longitudinal meta-analysis, this dissertation shows that the relationship between affect and performance is equivalently reciprocal (i.e. performance predicts affect to the same extent that affect predicts performance) and that the relationships between negative affect and performance and positive affect and performance are similar in magnitude (i.e. there is no positive-negative asymmetry). This dissertation also suggested that positive affect and negative affect are compatible with a broad performance construct (i.e. task performance, OCB, CWB and withdrawal). Finally, this dissertation examined important measurement moderators and found: (a) affect is reciprocally related to episodic performance; (b) affect and performance are reciprocally related when time between measurements are longer than a month; and (c) state affect measures and trait affect measures both have reciprocal relationships with performance. This meta-analysis benefits the organizational sciences by providing support for existing theories of affect as a predictor of performance (e.g. (")happy-and-productive(") theories) and by validating theories which suggest that affect and performance are reciprocally related.

Show moreThis dissertation explores the role of altruistic punishment, the act of punishing outsiders perceivedto harm members of one's group at a personal cost, in explaining individual motivations toparticipate in inter-group violence. It first develops a social theory of this type punishment. Thistheory argues that an egalitarian social logic may be key to understanding motivations of parochialaltruism, and that one's social environment may influence thresholds of anger needed to inducepunishment behavior. Empirically, it conducts two survey-experimental studies. The first experimentutilizes subject partisan identity in the context of American politics and hypothetical acts ofviolence to study altruistic punishment behaviors among two different populations in the US. Thesecond experiment utilizes a comparative sample of American, German, and Kurdish participantsto assess whether priming for anger tied to acts of political violence by outsiders against theirrespective in-group increases support for a hypothetical in-group (")punisher(") of these outsiders.The results of these studies offer two key findings: (1) anger induced costly punishment of outgroupperpetrators may be conditional on egalitarian attitudes; (2) this relationship is contextualand varies across population. The findings cautiously suggest two conclusions. First, there may beevolutionary and neurological mechanisms that promote participation in inter-group conflict andthat superficial characteristics such as ethnicity, religion, and ideology may work in tandem withbiological factors. Second, it suggests that social and political environments may be useful formodulating, or exacerbating, the role of anger in the decision to participate in inter-group conflictactivities.

A sample of students (N = 158) chose to participate in a survey asking questions about their perceptions of the amount, depth, and inappropriateness of teacher political disclosure, as well as whether or not they agreed with their professor's disclosed political ideology. The questionnaire also measured student perceptions of the teacher's subsequent competence, goodwill, trustworthiness, student state motivation, and student affective learning (content and teacher). The data revealed negative relationships between perceived inappropriateness of political disclosure and perceived competence and goodwill of the professor. Another finding of this study was that students who disagreed with their professors' disclosed political views tended to perceive those professors as less competent and trustworthy, and reported lower state motivation and affective learning.

Show moreRecognizing emotion from facial expressions is an essential skill for effective social functioning and establishing interpersonal relationships. AspergerÃ‚Â's Disorder (AD) and Social Phobia (SP) are two clinical populations showing impairment in social skill and perhaps emotion recognition. Objectives: The primary objectives were to determine the uniqueness of facial emotion recognition abilities between children with AD and SP relative to typically developing children (TD) and to examine the role of expression intensity in determining recognition of facial affect. Method: Fifty-seven children (19 AD, 17 SP, and 21 TD) aged 7-13 years participated in the study. Reaction times and accuracy were measured as children identified neutral faces and faces displaying anger, disgust, fear, happiness, and sadness at two different intensity levels. Results: Mixed model ANOVAs with group and emotion type revealed that all children responded faster and more accurately to expressions of happiness, but there were no other group differences. Additional analyses indicated that intensity of the displayed emotion influenced facial affect detection ability for several basic emotions (happiness, fear, and anger). Across groups, there was no pattern of specific misidentification of emotion (e.g., children did not consistently misidentify one emotion, such as disgust, for a different emotion, such as anger.) Finally, facial affect recognition abilities were not associated with behavioral ratings of overall anxiety or social skills effectiveness in structured role play interactions. Conclusions: Distinct facial affect recognition deficits in the clinical groups emerge when the intensity of the emotion expression is considered. Implications for using behavioral assessments to delineate the relationship between facial affect recognition abilities and social functioning among clinical populations are discussed.

Show moreSchizotypy is a sub-threshold syndrome associated with schizophrenia. Much of the research on schizotypy concerns its component features, one of which being blunted or constricted affect. While several investigations have addressed this common (")negative(") symptom within the context of schizophrenia, few have focused on schizotypy directly, and none have utilized psychophysiological measurement to examine affective constriction. The present investigation uses facial electromyography (EMG) to measure patterns of affective expression within a psychometrically defined schizotypal population when presented threatening and distressing pictures from the IAPS. Twenty-eight individuals with elevated schizotypal features and 20 healthy controls were recruited for this investigation. The participants observed the series of pictures and provided self-report ratings of affective valance and arousal while their physiological responses were recorded. The protocol used here closely matched that used by Bradley and Lang (2007) and produced a similar pattern of results across all participants on self-reported ratings and physiological measures. Results further suggest that those with schizotypal features did not differ from control participants in self-reported ratings of negative affect or autonomic arousal. A three-way interaction in facial EMG measurement revealed that while schizotypic males demonstrated the expected pattern of blunted facial affective expression, schizotypic females displayed the opposite pattern. That is, females with psychometrically schizotypy demonstrated significant elevations in negative facial affective expression while viewing distressing pictures. We argue that these findings reflect unidentified sex differences in affective expression in schizotypy, and we discuss implications for assessment and diagnostic procedures among individuals with personality disorders.

The present study examined social anxiety severity on a continuum and how it related to affective and cognitive empathy in 684 nonpsychiatric adults (77% female). Participants completed an online battery of measures that included: a self-report measure of social anxiety severity (Fear of Negative Evaluation), a self-report measure with subscales for affective and cognitive empathy (Interpersonal Reactivity Index), and a behavioral measure of cognitive empathy (Reading the Mind in the Eyes Task; MIE). After statistically covarying for general anxiety severity, biological sex moderated the relationship between social anxiety severity and performance on the MIE task. In women, a higher severity of social anxiety related to better performance on the MIE. This relationship was not statistically significant in men. IRI subscale scores did not show significant main effects or interactions with sex in relation to social anxiety. The findings suggest a possible difference in how each sex experiences and/or develops social anxiety. This has implications for assessment and treatment. Future research should examine these relationships in more diverse psychiatric samples.

Affective design is an umbrella term for research and practice being conducted in diverse domains, all with the common thread of integrating emotional aspects of use into the creation of information products. This thesis provides a review of the current state of the art in affective design research and practice to technical communicators and others involved in traditional HCI and usability enterprises. This paper is motivated by the developing technologies and the growing complexity of interaction that demand a more robust notion of HCI that incorporates affect in an augmented and holistic representation of the user and situated use.

Show moreFlat affect (i.e., diminished expressivity) and self-reported anhedonia (i.e., lack of pleasure) are associated with many psychiatric disorders. There is a need to examine the relationship between specific anhedonia subtypes and flat affect in a non-clinical sample. Forty-seven undergraduate students (59% male; mean age 20.37; SD = 4.74) completed self-report questionnaires assessing four subtypes of anhedonia - consummatory/anticipatory by social/non-social. Participants then viewed 15 randomly-presented pictures (five neutral, ten negative) from the International Affective Pictures System while facial muscle activity (electromyography; EMG) was recorded. Male participants reporting a greater level of anhedonia, particularly consummatory social anhedonia, showed greater EMG activity change in the corrugator supercilii muscle to negative pictures, as compared with neutral pictures. Females showed the opposite pattern: more consummatory social anhedonia related to less EMG activity change in the corrugator muscle. In summary, consummatory social anhedonia in particular showed a strong relationship with facial expressivity that interacted with sex. In the presence of more consummatory social anhedonia, males show more negative facial reactions to negative stimuli while females show a more flattened affect. These findings may help explain discrepancies in existing research examining anhedonia and flat affect in clinical populations and have implications for etiology and treatments.

Show moreCounterproductive work behaviors (CWBs) are an expensive phenomenon for organizations, costing billions of dollars collectively each year. Recent research has focused on justice perceptions as predictors of CWBs, but little research has been conducted on the specific types of counterproductive work behaviors (i.e., sabotage, withdrawal, production deviance, abuse, and theft) that result from specific organizational justice perceptions (i.e., distributive, procedural, interpersonal, and informational) and the mediating effect of state affect. The current paper meta-analyzed the relationships between justice, CWB, and state affect and found that justice was negatively related to dimensions of CWB and state positive/negative affect were negatively/positively related to CWB dimensions, respectively. However, mediation of the relationship between justice and CWB by state affect was inconsistent across justice types and CWB dimensions. These findings suggests that, while managers should maintain an awareness of justice and state affect as individual predictors of CWBs, the current study does not necessarily support the claim that state affect explains the relationship between justice and counterproductive work behavior dimensions.

This new instrument is designed specifically to measure the level of positive affect towards the subject of science in preservice elementary teachers. Confirmatory factor analysis reveals the instrument loads on the single factor, positive affect. Reliability is robust, with Cronbach's alpha of .96. Positive affect has shown to predict future levels of engagement in domain specific academic subjects (Ainley (&) Ainley, 2011) and is expected to aid preservice teachers in understanding the complex relationship between their students' interest and enjoyment of science with their own. This research contributes to the important role of emotion in preservice teachers' attitudes toward the subject of science and how it may affect the way they teach it to their future students.

Show moreAs the field of affect recognition has progressed, many researchers have shifted from having unimodal approaches to multimodal ones. In particular, the trends in paralinguistic speech affect recognition domain have been to integrate other modalities such as facial expression, body posture, gait, and linguistic speech. Our work focuses on integrating contextual knowledge into paralinguistic speech affect recognition. We hypothesize that a framework to recognize affect through paralinguistic features of speech can improve its performance by integrating relevant contextual knowledge. This dissertation describes our research to integrate contextual knowledge into the paralinguistic affect recognition process from acoustic features of speech. We conceived, built, and tested a two-phased system called the Context-Based Paralinguistic Affect Recognition System (CxBPARS). The first phase of this system is context-free and uses the AdaBoost classifier that applies data on the acoustic pitch, jitter, shimmer, Harmonics-to-Noise Ratio (HNR), and the Noise-to-Harmonics Ratio (NHR) to make an initial judgment about the emotion most likely exhibited by the human elicitor. The second phase then adds context modeling to improve upon the context-free classifications from phase I. CxBPARS was inspired by a human subject study performed as part of this work where test subjects were asked to classify an elicitor's emotion strictly from paralinguistic sounds, and then subsequently provided with contextual information to improve their selections. CxBPARS was rigorously tested and found to, at the worst case, improve the success rate from the state-of-the-art's 42% to 53%.

Show moreThe focus of this dissertation is on creating Adaptive Intelligent User Interfaces to facilitate enhanced natural communication during the Human-Computer Interaction by recognizing users' affective states (i.e., emotions experienced by the users) and responding to those emotions by adapting to the current situation via an affective user model created for each user. Controlled experiments were designed and conducted in a laboratory environment and in a Virtual Reality environment to collect physiological data signals from participants experiencing specific emotions. Algorithms (k-Nearest Neighbor [KNN], Discriminant Function Analysis [DFA], Marquardt-Backpropagation [MBP], and Resilient Backpropagation [RBP]) were implemented to analyze the collected data signals and to find unique physiological patterns of emotions. Emotion Elicitation with Movie Clips Experiment was conducted to elicit Sadness, Anger, Surprise, Fear, Frustration, and Amusement from participants. Overall, the three algorithms: KNN, DFA, and MBP, could recognize emotions with 72.3%, 75.0%, and 84.1% accuracy, respectively. Driving Simulator experiment was conducted to elicit driving-related emotions and states (panic/fear, frustration/anger, and boredom/sleepiness). The KNN, MBP and RBP Algorithms were used to classify the physiological signals by corresponding emotions. Overall, KNN could classify these three emotions with 66.3%, MBP could classify them with 76.7% and RBP could classify them with 91.9% accuracy. Adaptation of the interface was designed to provide multi-modal feedback to the users about their current affective state and to respond to users' negative emotional states in order to decrease the possible negative impacts of those emotions. Bayesian Belief Networks formalization was employed to develop the User Model to enable the intelligent system to appropriately adapt to the current context and situation by considering user-dependent factors, such as: personality traits and preferences.

Title: RISK FACTORS IDENTIFIED IN COLLEGE STUDENTS EXHIBITING SOCIAL PHOBIA.
Creator: Wallace, Kasie, McConnell, Daniel, University of Central Florida
Abstract / Description: College life is a unique experience in the life of many young adults that presents many challenges for which they might not be prepared, including living away from home and adapting to a new social and academic environment. In particular, these experiences may be particularly adverse for students with social phobia and may be predictors of academic and social problems, and may even predict dropout. The purpose of the present research is to identify possible connections between socially phobic...
Show moreCollege life is a unique experience in the life of many young adults that presents many challenges for which they might not be prepared, including living away from home and adapting to a new social and academic environment. In particular, these experiences may be particularly adverse for students with social phobia and may be predictors of academic and social problems, and may even predict dropout. The purpose of the present research is to identify possible connections between socially phobic tendencies and the social, emotional, and overall well-being of college students. Social phobia itself is an unnecessary and overwhelming fear of being scrutinized by others (National Institute of Mental Health 2009). By implementing the use of four psychological tests: the Social Phobia and Anxiety Inventory, Positive and Negative Affect Schedule, College Affiliation Questionnaire, and Life Orientation Test, this research sought to investigate the correlations existing between college students' self-reports on these measures through the use of the UCF Sona system. Students' personal characteristics and demographics were also examined correlationally along with their self-reports on all four measures. A total of 165 participants were used in this study. After gathering descriptive statistics from each test and their demographics, correlations were run between the four tests and then between demographic information and tests. The results showed social phobia having a positive correlation with negative affect and a negative relationship with positive affect. In turn, negative emotion was correlated with a lowered overall life orientation and a more pessimistic mindset. No strong correlations were identified between psychological tests and student characteristics as was previously thought. Overall, there are definite indicators that social anxiety has a negative impact on one's quality of life and emotions, however, more research needs to be done with more diverse sampling and different methodology to see if there is a link between particular student characteristics and prevalence rates of social anxiety within those characteristic subsets.

Show moreABSTRACT The problem of practice addressed in this paper is the need for professional development training in the educational setting on the social, emotional, academic, cognitive, and behavioral needs of students who have experienced a traumatic event. The need identified exists due to the lack of knowledge, interest, and opportunity to partake in professional development training in an effort to understand the impact trauma has on academic achievement and the toll that is placed on the school environment. The purpose of this paper is to review research on childhood trauma, examine the psychological impact on student academic achievement, foster child resiliency, and develop a foundation for effectuating change through a school-based intervention program that concentrates on promoting recovery in affected children. Traumatic events are a very real part of life that becomes a societal problem when a very young mind has to cope with the aftermath of the event. A survey and two interviews were administered to inform the professional development framework of the needs of students and teachers along with research on social-emotional learning, psychological resilience, and recovery methods offering an informative vehicle for change that will significantly impact the child's life. Cultivating Resilience Through The Arms of Academics is a school-based professional development framework designed to educate teaching professionals on the psycho-social needs of trauma affected children while providing systematic interventions designed to help these children with the factors necessary for healing to the extent allowable by the public school system. Schools are targeted to provide the interventions necessary for healing due to their extensive influence on the children they serve. This program will provide children with an emotionally safe environment thus establishing a school climate that is conducive for learning. The interventions in the program promote healing for trauma victims, assist teachers by providing strategies to engage the trauma affected students, and addresses the psycho-social competence and educational performance of all children in the educational population.

Title: PERFORMANCE IMPLICATIONS OF ALTERNATIVE COLOR-CODESIN AIRPORT X-RAY BAGGAGE SCREENING.
Creator: Hilscher, Matthew, Jentsch, Florian, University of Central Florida
Abstract / Description: This research investigated both cognitive and affective influences of alternative color combinations in a search task paradigm. The effects of re-mapping the existing, comparatively arbitrarily color codes of baggage X-ray images, were explored. Alternative color-codes were evaluated for improving the economy of visual search in X-ray baggage screening. Using a 2 x 2 between-groups design, the perceptual aspects of color-codes varying in degree of visual agreeability (accordant or discordant)...
Show moreThis research investigated both cognitive and affective influences of alternative color combinations in a search task paradigm. The effects of re-mapping the existing, comparatively arbitrarily color codes of baggage X-ray images, were explored. Alternative color-codes were evaluated for improving the economy of visual search in X-ray baggage screening. Using a 2 x 2 between-groups design, the perceptual aspects of color-codes varying in degree of visual agreeability (accordant or discordant) and color contrast (high or low) were examined in terms of efficiency (reaction time) and effectiveness (detection accuracy). Three hypotheses were put forth; two postulated main effects for color contrast and for visual agreeability, and a third postulated an interaction. Additionally, for comparison purposes, a fifth group of participants was presented with a stimulus condition that represented the current industry standard for colorizing X-ray images. Out of 100 volunteers, data were usable for 95 participants who had been randomly assigned to one of five conditions. All participants were exposed to the same screening task. The screening task required participants to view 153 X-ray images in random order. Of these images, 36 contained a single threat item (knife, scissor, gun) among clutter. Analyses of variance revealed significant differences between conditions with respect to detection accuracy. Implications are that high-color contrast improves detection accuracy; specifically with respect to correct rejections, and that this effect on performance can be moderated by psycho-emotional mechanisms. Specifically, the impact of color-contrast was significantly more pronounced under conditions of accordant color combinations. Theoretical underpinnings and applications to other domains are discussed.
