Previous researchers have often speculated about the role of risk taking in creativity, however this association has rarely been systematically investigated. This thesis explores the association between domain specific risk taking and creativity in human participants. It presents a systematic review of the speculations and scientific studies which aimed at uncovering the association between creativity and risk taking in various populations. This discussion aims to bring together the current knowledge centred around the link between risk taking and creativity and poses two overarching questions – Are creative individuals risk takers and if so, is this association domain specific? In five studies, the present research investigated these questions and found that creativity is strongly associated with risk taking in the social domain (but not in the financial, ethical, health/ safety or recreational domains). Additionally, with an aim to further disentangle the association between creativity and risk taking in specific populations and social situations, this thesis explored creativity in a specific group of individuals (sexual minority) who are speculated to be highly creative and are known to be more likely to take health/ safety risks such as smoking tobacco, consuming illegal drugs or engaging in unsafe sexual encounters. It was found that sexual minority (specifically bisexual individuals) were highly creative and were also more likely to take risks in various domains. As opposed to the sexual minority, another group of individuals in which creativity and risk taking are hypothesised to be different, consists of individuals who subscribe to the right-wing socio-political ideologies. As predicted, individuals who affiliated to the right-wing socio-political ideologies (in the United States) were found to be low on creativity and were significantly less likely to take risks, specifically in the social domain. A mediating role of social risk taking on the relationship between sociopolitical attitudes and creativity was also found. The research work presented in this thesis illustrates the role that social risk taking plays in creativity and paves way for the development of new ways to foster creativity.

This thesis takes as its starting point the observation that the authorship of the creative product of orchestral performances has been, and continues to be, over-attributed to the conductor. This is reflected both in popular perceptions and in the scholarly attention given to the conductor's leadership role, as well as in orchestral practices which privilege the conductor's artistically superior position within the orchestra through rehearsal and performance rituals and in remuneration and marketing. Although existing research has challenged the perception that the authority of the conductor is absolute, none has offered alternative explanations for how best to attribute the authorship of orchestral performances. Through a three-phased mixed-methods empirical study including an online questionnaire, in-depth interviews, and a newly developed method of data collection utilising an online variation of video-stimulated recall to capture musician experiences in real-life rehearsal and performance settings, this research contributes to an understanding of the social psychology of orchestral performance by identifying what prompts musicians' decision-making regarding how and when to play their parts. The analysis of the data has resulted in the development of a theoretical Framework of Influence and Action in Orchestral Performance that offers a new way of conceptualising authorship in performance through a 'theory of influence'. It concludes with an exploration of the implications of this revised view of authorship for existing orchestral practices, group creativity research, and our understanding of how the relationships enacted in the micro-socialities of orchestral performance reflect larger social formations.

Psychological factors specific to overuse injury pain in physical activity contexts were explored within a social identity theoretical framework. Study 1 involved development of a method for designating overuse injury pain occurrence of hikers (N = 751), along with exploration of relationships between psychological measures, overuse injury pain occurrence, and effort levels. The findings of this cross-sectional, mixed-methods investigation revealed that social identification, social identity content, and mental toughness differentiated hikers who incurred overuse injury pain or selected a higher-effort behaviour from those who did not. From qualitative analysis, several social identity constructs (i.e., group member's presence, in-group status, social creativity, additional social identity content) emerged as contributors to overuse injury occurrence. The focus of Study 2 was a prospective examination of the aforementioned psychological factors in relation to overuse injury severity of hikers (N = 283). Additionally, the Test of Intentions to Reduce Effort (TIRE) was developed to identify individuals with susceptibility to higher overuse injury severity. Results provided evidence of factorial, construct, and predictive validity of TIRE factor scores. TIRE factors and social identity content significantly predicted higher severity of hikers' overuse injury pain. Mental toughness scores moderated the relationship between social identification and overuse injury severity. Study 3 consisted of a qualitative examination of social identity mechanisms of overuse injury pain in a physical activity context, CrossFit®, involving the presence of group leaders, and in which group members view each other. Findings revealed mechanisms pertaining to social identity content, in-group status, and social threats. Overall, the findings support a new means for assessing overuse injury occurrence and susceptibility to higher overuse injury severity, whilst demonstrating the potential applicability of social identity theory to the study of overuse injury. Knowledge gained may ultimately aid development of interventions to reduce overuse injury occurrence and severity of physical activity participants.
