Research purpose: The purpose of the study is to investigate the extent to which supervisors are universally perceived as abusive across those they supervise. I propose social learning theory and social information processing theory as theoretical bases for understanding collective impression formation among subordinates reporting to the same supervisor. The study, therefore builds on a growing body of abusive supervision literature by analysing intraclass correlations between subordinates' and their co-workers' perceptions of the same supervisor. Research motivation: Studies that examine whether or not subordinates of the same supervisor have similar perceptions of abuse are in short supply. Therefore, this study examines the possibility of objective impression formation with regards to abusive supervision so as to answer the question: Do subordinates and their co-workers mutually perceive the extent to which a supervisor's behaviour is abusive? Research design, approach and method: This study follows a cross-sectional approach to investigate the extent to which subordinates of the same workgroup mutually perceive their supervisor's behaviour as abusive. Purposive sampling was employed to recruit full-time employed Master's of Business Administration (MBA) students from six respected universities in the United States (US). Purposive sampling was further aided by snowball sampling where each subordinate was asked to get two of their own co-workers involved in the study. A total of 1,029 surveys were distributed and 693 completed surveys were returned. The final sample consisted of 210 sets of surveys where responses were received from the focal subordinate and two of his or her co-workers. An intraclass correlation coefficient (ICC) analysis was conducted to determine the strength of intra-group agreement regarding abusive supervision perceptions. Main findings: The results indicate that there is agreement between subordinates' and their co-workers' perceptions of abusive supervision as no significant differences were found between these two groups' assessments of the same supervisor's behaviour. The null hypothesis was accepted. A non-hypothesized finding is that dyadic tenure appears to influence the extent to which supervisory abuse is observed. That is, subordinates and their co-workers may view the same supervisor in the same light, the longer the duration of the supervisor-subordinate relationship. Limitations: The results should be interpreted, bearing in mind that there is limited literature available on abusive supervision at the group level. Furthermore, the results should be considered with caution as the perceptions of abusive supervision were only examined at one point in time, the use of snowball sampling method may be associated with the possibility of sampling bias, and that dyadic tenure was measured with a categorical response (i.e., not treated as a continuous variable). Finally, the results may not be generalisable to the South African context. Future research: It is suggested that future studies should investigate abusive supervision as a group-level phenomenon as few such studies currently exist. Additionally, future studies should examine the extent to which social learning and social information processing approaches contribute to the establishment of mutual perceptions about supervisory abuse. Researchers may also investigate the occurrence of abusive supervision at the group level through the lens of an alternative theoretical framework such as social identity theory. / Dissertation (MCom)--University of Pretoria, 2017. / Human Resource Management / MCom / Unrestricted

While both social information processing and cortisol secretion in childhood aggression have generated a great deal of interest and research in the past few decades, these social-cognitive and physiological components of aggressive behavior have not been examined in the context of an integrative model. This lack of an integrative framework may underlie some of the inconsistencies that have plagued the literature in this area to date, especially with respect to hypothalamic-pituitary-adrenal (HPA) axis functioning in aggressive children. This investigation tested a mediational model of the relationship between social-information processing, cortisol secretion, and reactive and proactive aggression. Specifically, it was hypothesized that social-information processing variables would mediate the proposed relationship between reactive and proactive aggression and cortisol secretion. One hundred and twenty-six children between the ages of 13 and 18 were administered the Child Behavior Rating Form (CBR), the Home Interview with Child (HIC), the Response Decision and Social Goals Instrument (RDSGI), the Antisocial Processes Screening Device (APSD), the Buss-Durkee Hostility Inventory (BDHI), the Children's Depression Inventory (CDI), and the Revised Children's Manifest Anxiety Scale (RCMAS). Each child also contributed two samples of saliva for cortisol assay, and each child's teacher completed a teacher-version of the APSD and the CBR. Regression analyses revealed no significant associations between proactive or reactive aggression and cortisol secretion, or between any of the social-information processing variables and cortisol secretion. Predicted associations between proactive and reactive aggression and social-information processing variables were found. Overall, therefore, the mediational model was not supported. However, cortisol secretion was found to be associated with both anxiety and depression, and exploratory analyses revealed significant associations between cortisol secretion and Psychopathy as measured by the APSD. Taken together, the findings suggest that while the specific relationship proposed here among social-cognitive, psychophysiological, and behavioral variables was not found, an integrative model examining each of these components may be useful in further investigations of the complex phenomenon of childhood aggression. / Ph.

Peer aggression and victimization are currently of national concern due to their high association with maladjustment. Moreover, peer aggression and victimization can occur as different forms (overt, relational) and functions (proactive, reactive), which are usually not examined within the same model. Peer aggression and victimization within the school context can be the result of individually developed negative social cognitions. These negative cognitions, based within social information processing theory, include outcome expectancies and values for pain and suffering. In addition, positive cognitions such as perceived social competence can decrease adverse outcomes such as peer aggression and victimization. This project seeks to take previous research and expand upon it in two ways: 1) examine overt, relational, proactive, and reactive aggression and victimization as separate constructs, within the same model, in association with outcome values, expectancies, and perceived social competence; and 2) examine the potential of extracurricular activities to serve as a buffer between maladjusted cognitions and aggression and victimization. In addition, this study will examine if these relationships differ by activity type, age and gender. Participants included 371 middle and high school students. Findings point toward the importance of examining the separate functions of aggression and victimization, as outcome values and expectancies are associated specifically with higher levels of proactive aggression and victimization and reactive aggression. Activity participation, particularly activities that are not associated with the school that the participant attends, seems to be serving as a buffer against maladjusted cognitions and functions of aggression and victimization. Specifically, having high efficacy for activity participation (ability to meet expectations within activity) serves a buffer for both reactive aggression and reactive victimization. Activity participation benefits appear to not be present if the individual is only participating because their parents are forcing them to be there. No group differences were found. These findings serve to demonstrate the importance of establishing fit of activity context for youth as well as their motivation for participation. More broadly, it is important to examine functions of aggression and victimization in the same model as the forms of aggression and victimization. By better understanding the moderating role of activities, schools can potentially have a low cost intervention tool for peer aggression and victimization difficulties.

Children’s social information processing (SIP) encompasses cognitive and behavioral sequence that underlies social responses. SIP in peer interactions is well studied. Less is known about SIP in mother-child interchanges. Youth who show one SIP pattern a hostile attribution of intent (HAI) bias—in peer interactions consistently exhibit externalizing symptoms. This relationship is less consistently observed for HAI biases toward mothers. I hypothesized that this inconsistent association reflects moderating factors; specifically, engaging in foundational parenting practices (monitoring/supervision, consistent discipline) would weaken the relationship between HAI biases toward mothers and externalizing behaviors. Logistic regression yielded limited support for hypotheses. Consistent discipline predicted externalizing behaviors in some contexts; however, moderator effects were not detected. Isolated parenting practices thus may not buffer against the risk of externalizing behaviors linked to HAI biases toward mothers. Future research might examine how different HAI biases (peer, mother, etc.) related to each other and outcome variables.

The internet has become an important social context in adolescence, and communicating online with friends has become a natural part of everyday life. The present cross-sectional study examined the effects of social cues and popularity on developing adolescent social cognitions in online settings using a sample of 90, 11- to 14-year-old students from British Columbia, Canada. Participants completed self-report cyber-bullying, cyber-victimization, and cyber-aggression motivation measures. Hostile intent attributions were obtained using an instrument containing 8 hypothetical vignettes, where potentially harmful messages were sent to the protagonist, but the sender’s intentions were ambiguous. The results show an increasing cyber-bullying and cyber-victimization trend from early- to mid- adolescence. There was some evidence to suggest that individuals in mid-adolescence were more sensitive to online social cues and popularity. Individuals in mid-adolescence were more likely to engage in cyber-aggressive behavior to obtain a material or social reward. Despite having a small sample size, this study provides a good foundation for further research examining developmental processes that underlie cyberbullying behavior. / Graduate
