The association between core disgust and moral disgust has been a particularly contentious issue within the emotion literature. Preliminary neurophysiological evidence appeared to support a hybrid theory of the relation between core disgust and moral disgust, suggesting reactivity to bodily moral disgust stimuli is similar to core disgust reaction patterns and reactivity to non-bodily moral disgust stimuli is similar to that of anger.  The aim of this project was to test this theory.  In Study 1, participants viewed and rated emotion video clips to ensure the video clips shown in Study 2 elicited the intended emotions. In Study 2, the selected video clips were shown while EEG and ECG data were collected.  It was hypothesized that there would be similar cerebral asymmetry, heart rate, and heart rate variability patterns between contamination-related core disgust and bodily moral disgust and between anger and non-bodily moral disgust. Although the results of this study did not fully support these hypotheses, preliminary evidence was found to support the hybrid theory of disgust. Based on the participant ratings and observed frontal asymmetry scores, similarities were found amongst contamination-related core disgust and bodily moral disgust and with non-bodily moral disgust and anger. These results warrant further investigation into the disgust construct in order to continue to explore the validity of the hybrid theory of disgust. / Ph. D.

Extant research on temperament shows that it may be related to certain developmental outcomes. However, according to the goodness-of-fit hypothesis (Chess and Thomas, 1999), developmental outcomes are the result of how well the biological tendencies of an individual (i.e. temperament) fit with the contextual demands of their environment. Thus, temperament should only affect developmental outcomes as a function of their environmental context. The current study proposes that parent temperament may serve as an environmental context that interacts with adolescent temperament to affect the development of the adolescent emotion regulatory system. Structural equation modeling results revealed parent temperament, specifically parent effortful control, to moderate the relationship between adolescent temperament and the adolescent emotion regulatory system. Several gender differences were also found for both main and interaction effects. Adolescent negative affect was negatively related to emotion regulation for girls only. Parent effortful control moderated the relationship between adolescent effortful control and suppression use also for girls only. Parent effortful control moderated the relationship between adolescent surgency and emotion lability for boys only, and parent effortful control moderated the relationship between adolescent surgency and suppression for both boys and girls, but in opposite directions. The interaction term was negatively related to suppression for girls, and it was positively related to suppression for boys. Results have several implications for potential parenting interventions and may inform programs that teach emotion regulation strategies. / Ph. D.

Infant-directed registers are emotion communication, conveying feelings and intentions to infants and toddlers that may facilitate and modulate attention and language learning. As infants are attracted to emotion, it is essential to understand how infants process emotional information. This study used an infant-controlled habituation paradigm to examine how 7- to 15-month-old infants discriminate changes in visual emotion, auditory emotion, or visual+auditory emotion after being habituated to a bimodal emotion display. The purpose of this study was to examine which modality (facial emotion; vocal emotion) was more salient for infants to discriminate emotions in the context of bimodal stimulation. Infants were habituated to happy audiovisual displays then received four test trials, during which neither source of emotion information was changed (control), just the auditory emotion was changed, just the visual emotion was changed, or both sources of emotion information were changed. It was predicted that infants would show the greatest recovery of attention to a change in visual emotion than when only visual information was changed, but less than when both auditory and visual information were changed. However, the results showed that infants were equally sensitive to all three types of emotion change. These results are discussed in terms of concurrent conceptualizations of how emotion processing is related to negative bias and experience with two emotions. / Master of Science / When we interact with infants, we convey feelings and intentions to infants that may facilitate and modulate attention and language learning. As infants are attracted to emotions, it is essential that we understand how infants process emotional information. While previous studies have shown that infants are capable of discriminating different kinds of emotions, no known study has been done to examine whether infants would be more sensitive to a change in facial expression or in vocal expression when they experience both facial and vocal expressions together. To examine this, infants were habituated to happy audiovisual displays. Infants then watched four audiovisual displays that were 1) the same happy audiovisual display, 2) audiovisual display with happy face and fearful voice, 3) audiovisual display with fearful face and happy voice, and 4) audiovisual display with fearful face and fearful voice. It was expected that infants would look longer when facial expression was changed than when vocal expression was change, but less than when both facial and vocal expressions were changed. However, the results showed that infants were equally sensitive to a change in facial expression, vocal expression, and both facial and vocal expressions.

Studies examining impaired emotion recognition and perceptual processing in autism spectrum disorders (ASD) show inconsistent results (Harms, Martin, & Wallace, 2010; Jemel, Mottron, & Dawson, 2006), and many of these studies include eye tracking data. The current study utilizes a novel task, emotion recognition of a dynamic talking face with sound, to compare children with ASD (n=8; aged 6-10, 7 male) with mental age (MA) and gender matched controls (n=8; aged 4-10, 7 male) on an emotion identification and eye tracking task. Children were asked to watch several short video clips (2.5-5 seconds) portraying the emotions of happy, sad, excited, scared, and angry and identify the emotion portrayed in the video. A mixed factorial ANOVA analysis was conducted to examine group differences in attention when viewing the stimuli. Differences in emotion identification ability were examined using a t-test and Fisher's exact tests of independence. Findings indicated that children with ASD spent less time looking at faces and the mouth region than controls. Additionally, the amount of time children with ASD spent looking at the mouth region predicted better performance on the emotion identification task. The study was underpowered; however, so these results were preliminary and require replication. Results are discussed in relation to natural processing of emotion and social stimuli. <i>[revised ETD per Dean DePauw 10/25/12 GMc]</i> / Master of Science

Child maltreatment impacts approximately one in seven children in the United States, leading to many adverse outcomes throughout life. Adolescence is a time period that is critical for the development of self-regulation, as it is when the prefrontal cortex is actively developing. Existing research demonstrates the numerous adverse effects maltreatment may have on self-regulation, which encompasses executive function and emotion regulation abilities. However, there is little research examining how abuse and neglect may differently affect the developmental trajectories of executive function and emotion regulation throughout adolescence and into young adulthood. In the current study, 167 adolescents participated approximately annually at six time points, from ages 14 to 20. At each of the six time points, adolescents completed three executive function tasks as well as self-report questionnaires on their emotion regulation abilities and strategies. Information on maltreatment experienced from ages 1 to 13 was collected when the adolescents were approximately 18 to 20 years of age. Conditional growth curve models were utilized to test the differential effects of abuse and neglect on the growth trajectories of executive function abilities and emotion regulation difficulties and strategy use. The results revealed that neglect was associated with developmental changes in working memory abilities, such that greater amounts of neglect were associated with slower increases in working memory abilities across ages 14 to 20. Further, abuse was associated with developmental changes in difficulties in emotion regulation abilities, such that greater amounts of abuse were associated with larger increases in difficulties in emotion regulation abilities from ages 14 to 20. Finally, neglect was associated with the initial level (at age 14) of difficulties in emotion regulation abilities, such that greater levels of neglect were associated with higher initial levels of difficulties in emotion regulation abilities as compared to individuals with lesser amounts of experienced neglect. These findings suggest that working memory development during adolescence into young adulthood may be more vulnerable to childhood neglect and that both abuse and neglect in childhood may have adverse impacts on the development of emotion regulation abilities. / M.S. / Child maltreatment impacts approximately one in seven children in the United States, leading to many adverse outcomes throughout life.

In the majority of the depression literature, there has been little attention paid to the mechanisms underlying the differences that occur among individuals with this label. In a theoretical paper by Shenal, Harrison, and Demaree (2003), they proposed that the differences in depression symptomology may be due to differences in the function (and dysfunction) of the right and left frontal lobes. They go on to explain that each frontal lobe may have a direct influence on patterns of depression symptomology. In the current experiment there was an effort to look at performance differences among depressed and non-depressed males on a tests of affective memory (AAVLT) and functioning for the left (COWAT) and right (RFFT) frontal lobes. Results were non-significant for group based differences but other significant effects were found. Reliable findings included a primacy effect for the recall of words from the negative word list from the AAVLT, whereas t a "normal" primacy and recency effects were found for the recall of positive and neutral word lists. There were also significant differences (across trials) for both groups suggesting a "normal" learning curve. It is thought that the non-significant comparisons among the groups are likely due to the qualitatively mild depression scores among participants, which is likely not adequate to capture the level of dysfunction discussed in the original hypothesis. / Master of Science

Several lines of research on converge for the conclusion that high and low hostile men differ with respect to autonomic regulation of stress. The functional cerebral systems approach has provided a theoretical framework to account for this finding across the individual sensory, motor, and premotor modalities. The current experiment extends and elaborates upon a functional cerebral systems based model that posits a role for the right frontal region in regulation of sympathetic tone after stress. The experiment builds upon prior work illustrating the utility of this model to stress by positing mild dizziness as a potential frontal lobe stressor demonstrating hostility group differences in sympathetic arousal. Dizziness was induced by brief clockwise angular rotation about the vertical neuroaxis. Consistent with vestibular research indicating clockwise rotation impacts the right hemisphere (relative to counterclockwise rotation), it was expected that hostile individuals would exhibit higher skin conductance levels after rotation compared with low hostile individuals. The experiment also included a dichotic listening task both before and after rotation to examine the effects of rotary stress on dichotic phoneme identification. The experiment was conducted in three blocks: A dichotic listening task comprised the first block, followed by application of rotary stress as the second block, and a follow-up dichotic listening task post- rotary stress. It was predicted that rotation would induce an auditory perceptual shift towards the left ear. Results confirmed expected group differences in sympathetic response to rotary stress. High hostiles had greater overall skin conductance immediately following rotation. High hostiles failed to habituate skin conductance levels to mild rotation 7 minutes post-rotary stress. Lateralized effects of skin conductance remain unconfirmed at this time. No group differences were found for either block of the dichotic listening task. Overall, results are interpreted to support a model of frontal region capacity limitation for regulation of stress, including vestibular dysfunction. / Master of Science

Toddler-aged children are expected to shift from being solely dependent on parents to regulate their emotion (e.g., Fox & Calkins, 2003) to being able to independently regulate their emotions (Calkins & Johnson, 1998). Mothers' responses to children's negative emotions are expected to influence this development. Children's temperamental negative reactivity was found to moderate the effect of mothers' socialization attempts on children's regulatory behaviors, as suggested by previous theoretical and empirical work (e.g., Putnam, Sanson, & Rothbart, 2002; Rothbart & Bates, 1998). Specifically, highly negatively reactive children showed no correspondence between their mothers' attention-shifting strategies and their own attentionshifting regulation behaviors. This finding is consistent with the proposed process by which temperamentally reactive children become overaroused and unreceptive to mothers' socialization efforts (Hoffman, 1983; Scaramella & Leve, 2004). Lastly, children's reactivity did not moderate the effects of mothers' emotion-intensifying socialization on children's emotion-intensifying regulation behaviors, a finding which deserves further study.

The purpose of the current study was to examine the path of perceived parenting styles, emotion recognition, emotion regulation, and psychological well-being in terms of depression, obsessive-compulsive disorder and social anxiety symptoms consequently. For the purpose of this study 530 adults (402 female, 128 male) between the ages of 18 and 36 (M = 22.09, SD = 2.78) participated in the current study. The data was collected by a questionnaire battery including a Demographic Category Sheet, Short-EMBU (Egna Minnen Betraffande Uppfostran- My Memories of Upbringing), &ldquo / Reading the Mind in the Eyes&rdquo / Test (Revised), Emotion Regulation Questionnaire, Emotion Regulation Processes, Beck Depression Inventory, Liebowitz Social Anxiety Scale, Maudsley Obsessive Compulsive Inventory, White Bear Suppression Inventory, Thought-Action Fusion Scale, and Emotional Approach Coping Scale. The psychometric properties of Emotion Regulation Questionnaire and Emotion Regulation Processes were investigated and found to have good validity and reliability characteristics. The three sets of hierarchical multiple regression analyses were conducted to reveal the significant associates of psychological well-being. As expected, the results of the current study revealed that perceived parenting styles, different emotion regulation strategies and processes had associated with psychological well-being in terms of depression, obsessivecompulsive disorder and social anxiety symptoms. The findings, and their implications with suggestions for future research and practice, were discussed in the light of relevant literature.
