Rejection sensitivity (RS) is defined as the tendency to anxiously anticipate, perceive, and overreact to real or perceived rejection and can have significant effects on interpersonal relationships. Previous research has shown the negative social effects of RS, particularly in the context of romantic relationships, but less is known about the cognitive implications of having high levels of RS. Specifically, it is unclear whether a heightened sensitivity to rejection is associated with enhanced error processing or feedback evaluation. The current study used EEG to examine the effect of RS on two event-related potential (ERP) components associated with error monitoring and feedback evaluation, error-related negativity (ERN) and feedback-related negativity (FRN), respectively. Participants completed a Flanker task during which they received either social (faces) or nonsocial (symbols) feedback about their performance. Results showed an increased ERN on error trials for individuals with higher RS. Although the FRN was not influenced by RS, there was an expectancy-valence interaction. FRN amplitude was also sensitive to condition, with correct feedback eliciting significantly more negative FRN in the social condition compared to the nonsocial condition; FRN for unexpected feedback was also greater in the social condition. Overall, the results suggest a relationship between error monitoring and RS, as well as a relationship between social information and feedback processing. Future research should further explore the relationship between rejection sensitivity, attention, and social feedback processing.

Feeling that a partner is responsive to one’s needs is crucial to intimacy (Reis, Clark, & Holmes, 2004). Just as the well-known expression, “the squeaky wheel gets the grease,” suggests that people who voice the most complaints elicit the most support from others, existing theory and research suggest that the more one expresses one’s emotions, the more one’s partners should behave responsively—with caring, understanding, and validation (Reis et al., 2004; Reis & Shaver, 1988). However, I suspected that when a person frequently expresses negativity, individual negative disclosures seem less diagnostic of true distress, and thus elicit less responsiveness from partners. Building on Biernat, Manis, and Nelson’s (1991) shifting standards model, I predicted that people use person-specific standards—taking into account the expresser’s typical (baseline) level of negative expressivity—when interpreting a close other’s negative disclosures. Results of six studies employing both correlational and experimental methods supported the hypothesis that people who frequently express negativity may have the severity of their distress underestimated and elicit less concern and responsiveness from their partners when they make negative disclosures. These findings provide insight into why even close relationship partners may fail to behave responsively to each other’s negative disclosures.

Through my PhD thesis, ‘Porno-graphing: ‘dirty’ subjectivities & self-objectification in contemporary lens-based art’, I use the term ‘porno-graphing’ to group together and examine lens-based artworks where artists use as art-material sexual situations or sets of sexual dynamics present in their life independently of their art practice. I consider how artists act upon these sexual situations in order to make art out of them, the art-results they produce and their means of sharing them with audiences. I argue that the artists whose work I examine, use sexual situations that can potentially be perceived as ‘taboo’; for example Leigh Ledare involves incest-related dynamics in Pretend You Are Actually Alive and Kathy Acker with Alan Sondheim implicate child-sexual subjectivities in the Blue Tape. I argue that they choose and use these situations to self-submit into the ‘dirtiness’ of their sexual and artistic subjectivities and in doing so to negotiate how subjectivity is produced. To do so, they use visual vocabularies of autobiography to self-objectify into roles as both artists, e.g. assuming positions such as the white male pornographer-exploiter (the work of Ledare) and as sexual subjects, e.g. ‘perverted’ or hyper-sexual objects of desire (the work of Lo Liddell). In embracing these roles they create ‘intensified encounters’ (Edelman & Berlant, 2014) between the artist, the art-object and the viewer, to interrogate ‘normative’ and ‘antinormative’ patterns of meaning-making and value-attribution regarding subjectivity and art.

Error-related Negativity (ERN) is an event-related potential elicited by the commission of errors. It appears as a negative deflection peaking between 50ms and 100ms after an erroneous response. Previous literature demonstrated that individuals who suffer from either anxiety or depression display a higher ERN amplitude compared to a control group. It has also been shown that people with ADHD display a lower ERN amplitude, suggesting that traits of this disorder, such as impulsivity, impair sensitivity to errors. Based on these findings, we investigated which disorder has more weight on the variance in amplitude of the ERN. We recruited thirty-eight students at East Tennessee State University and gathered data on their level of anxiety, depression, and ADHD through completion of three surveys: the Beck Anxiety Inventory, Beck Depression Inventory, and the ADHD self-report scale. Subsequently, participants were asked to perform a modified Flanker task while their EEG neural activity was collected through a 32-channel EEG cap. ERN amplitude for error responses was significantly higher than ERN amplitude for correct responses. In addition, error responses produced a large P300 component of the event-related potential.

Father involvement was examined multidimensionally using fathers' and children's reports. A total of 61 fathers and 143 children (intact families and stepfather families) from the Avon Brothers and Sisters Study (ABSS) participated in the current study. Measures of father involvement including engagement in shared activity, monitoring, positivity, and negativity were completed by fathers and children. Agreement between father and child reports of involvement was assessed, involvement was compared between biological fathers and stepfathers, and involvement was predicted statistically using father and child factors (e.g., age, gender). There were modest significant associations between fathers' and children's reports of monitoring of positive events, and father-child positivity. Compared to biological fathers, stepfathers did less monitoring of positive events, and were less positive towards their children. Biological relatedness was a significant predictor of monitoring positive events, monitoring negative events, and positivity. Consistent with previous theoretical and empirical accounts, this study demonstrated that being biologically related to your child influences the level of involvement in fathers. / Master of Science

Bisexual individuals experience negativity toward their identities from heterosexual as well as gay and lesbian individuals. While there is a large body of research on the negative mental health consequences due to bi-negativity among individuals who identify as bisexual, little research exists exploring the relational impacts of bi-negativity. Informed by symbolic interaction theory and minority stress theory, this study investigated the impacts of attitudes regarding bisexuality on relationship satisfaction in female same-gender couples with at least one bisexual-identified individual through the following research questions: (a) How, if at all, do the attitudes toward bisexuality of individual partners influence perceptions of relationship satisfaction? and (b) How do partners negotiate the influence of attitudes toward bisexuality on their relationship? To address these questions, data from semi-structured interviews of eight female same-gender couples were analyzed using constructivist grounded theory methodology. Findings indicated that couples moved through a process of the following: pre-relationship factors, relationship formation, relational emotion work, and shared relational meaning. Couples additionally are influenced in each phase of the process by macrosystemic oppressions. Clinical implications to assist mental health professionals better serve these couples were determined. / Doctor of Philosophy / Bisexual individuals experience negativity toward their identities from heterosexual as well as gay and lesbian individuals.

The negativity bias is a phenomenon that is characterized by infants being more influenced by, attending more to, and responding to more negative emotion information from the environment than positive emotion information. This study used a Tobii© T60 eye-tracking system to examine differences in 8- to 12-month-old infants' latencies to disengage from a centrally-presented face for three different emotion conditions-happy, sad, and fear. The events also varied by motion type-static versus dynamic. Additionally, infants' locomotor experience and parental affect served as two additional measures of experience, and assessed for their contributions to the infants' negativity bias. It was expected that infants would show longer latencies to disengage from the negative emotion events (fear or sad) compared to the positive emotion event (happy), but also that the latencies would be augmented by event type (dynamic > static), locomotion experience (high > low), and parental affect (higher negativity > lower negativity). Although infants showed more attention to dynamic than static emotion displays (especially on the speaker's mouth), and more attention to happy and sad compared to fear displays, no consistent effect of emotion type was found on infants' attention disengagement. Thus, no evidence for a negativity bias was seen. The results are interpreted with respect to possible contributions of the bimodal nature of emotion expression in the current study as well as age-related attentional differences in responding to a wide range of emotion cues. / Master of Science

[Truncated abstract] Some children with Specific Language Impairment (SLI) show poor performance on behavioural tasks designed to measure rapid auditory processing, such as the Repetition Test developed by Tallal and colleagues. Stemming from concerns about whether this task reflects higher-order, cognitive variables, this thesis sought to determine whether the performance deficits SLI children show were evident at the neurophysiological level, with minimal cognitive influences, such as attention, using paradigms designed to elicit the mismatch negativity (MMN) and late discriminative negativity (LDN). In the first two studies, a MMN paradigm, equivalent to the Repetition Test, was trialled with a group of 8 adults. In this paired paradigm, the second tone of a pair of pure tones ascending in frequency ('low'-'high') was occasionally replaced with a 'low' tone. The aim was to determine a 'long' and 'short' intra-pair interval (IPI) with which MMN was generated utilizing this paradigm and that were congruent with the Repetition Test findings (i.e., a long IPI at which SLI were able to perform the task, and a short IPI at which SLI children's performance was selectively impaired). In Study One, MMN to a within-pair frequency change was generated with the 30 ms IPI, but not the 700 ms IPI. The grouping parameters of the temporal window of integration (TWI) and temporal distinctiveness were considered less than optimal for the grouping of the pairs presented at 700 ms IPI for the pre-attentive system to register the within-pair frequency change. ... The frequency difference limens (DLs) of the SLI group were significantly higher than a group of 18 normally developing age- and intelligence-matched peers, but there was no significant difference between the groups in their performance on a control intensity discrimination task. The iii SLI group also showed poorer reading skills, yet frequency discrimination was related to oral language ability only. In the final study, MMN was measured to examine the pre-attentive neurophysiological basis of the SLI group's frequency discrimination deficit. Two frequency deviants that were just above each group's 75% DL on the frequency discrimination task were employed in a simple frequency change paradigm: 40 Hz difference for the control group, and 80 Hz difference for the SLI group. MMN and LDN were elicited in the group of 15 normally developing children to their 40 Hz suprathreshold frequency difference and to the 80 Hz difference. A significant MMN was not observed in the group of 13 SLI children to the 40 Hz difference, which was below their threshold level. However, despite discrimination at the behavioural level, MMN did not reach significance in the SLI group to their 80 Hz suprathreshold frequency difference, yet LDN was observed. MMN was larger in both groups for the 80 Hz difference. Furthermore, MMN and LDN amplitude to the suprathreshold deviants were predictive of both frequency and intensity DLs. These results suggested that SLI children have a pre-attentive neurophysiologically mediated insensitivity to small frequency differences, and that MMN (and LDN) to suprathreshold frequency deviants is a sensitive indicator of group discrimination differences and brain-behaviour relationships in children with and without SLI.
