Though the scientific study of stress is relatively new, not even one hundred years old, there has been robust inquiry and discovery in stress research since its instantiation. Yet, many unanswered questions remain on how specific stressors impact the mind, brain and body. Social threat is a pervasive form of stress for species that are organized in social hierarchies, like humans and some animals. Social evaluative threat (SET), occurring when there is potential for negative evaluation or rejection from others, is a pervasive and important form of stress in humans having many links to stress-related physiological outcomes which in turn have important implications for health outcomes. The brain is a critical component in the mind-brain-body-health connection, but less is known about SET at the neural level. Here in this thesis, there are three studies that characterize the neural circuitry that responds to SET. Using a novel imaging technique, arterial spin labeling, Study 1 asks whether SET-related brain circuitry is modulated by a SET-related trait level vulnerability, Fear of Negative Evaluation (FNE). Overall, Study 1 replicated previous work by showing SET-related reactivity in the left pregenual anterior cingulate cortex, right ventromedial prefrontal cortex (vMPFC) and medial periaqueductal gray and extended previous work by showing that changes in the left vMPFC and the right thalamus were predicted by FNE. Using blood oxygenation level-dependent imaging (BOLD), Study 2 asks whether SET influences the brain circuitry on which the formation of relational episodic memory relies. With the use of mediation analysis, it was found that SET impaired relational episodic memory, and that the impairment was a function of activity in the right parahippocampal cortex and bilateral vMPFC. Using BOLD imaging, Study 3 asks whether SET influences the brain circuitry that subserves working memory (WM). With the use of mediation analysis, it was found that SET impaired WM, and that the impairment was a function of activity in bilateral intraparietal sulcus. Links between mind, brain, body and health are discussed throughout this work.

This thesis examines the pervasive presence of the vulnerability of the human body in Charles Dickens’s writing. It demonstrates, through a collection and discussion of bodily references drawn from the range of Dickens’s novels, that the the body’s vulnerability is, in conjunction with the use of humour and the literalizing of metaphorical references to the body, a crucial and fundamental element of both Dickens’s distinctive style and of his enduring literary popularity. Chapter one provides evidence for the contention that a sense of physical vulnerability was particularly intense in the Victorian era and that Dickens shared this awareness as his social and humanitarian interests and activities illustrate. The following chapter focuses on Dickens’s more private concerns with the body, particularly upon his personal physical fears and experiences, the public attention given to his body as a result of fame, his continual denial of his own physical frailties, and the interplay between his body and his writing all of which provided impetus to his literature. Chapters three, four, and five examine consecutively the ways in which physical vulnerability—to damage, disease, and death, but most importantly to dismemberment— function in the novels. They do so on three broad levels: Character, Conversation, and Expression which depict in ascending order increasing bodily insecurity in Dickens’s texts. The Character level concerns the bodily forms and fates of Dickens’s characters. We see here that the more a player’s body is described the more vulnerable it will become, thus good-hearted heroes are virtually “bodiless” and suffer little physical pain while evil characters are described in great anatomical detail and come to bodily harm. Dickens metes out “bodily justice” on this level in that he ensures that characters who have transgressed the rules of good conduct in his fictional world are physically punished for their misdeeds and that bodily punishment is in direct proportion to the “crime” committed. On the Conversational level Dickens depicts extreme physical horrors by expressing these things humorously, by putting descriptions of them in mouths variously and interestingly accented, and, most significantly, by playing on the dual literal and metaphorical meanings of bodily references. Most of this anatomical dialogue is anecdotal and therefore unverifiable, hypothetical and therefore unlikely to happen, or professional, i.e., spoken by “bodily experts” such as doctors or undertakers, and therefore irrefutable. Here exaggeration and extremes attract readers who are simultaneously fascinated and repelled by what characters say of the body. Dickens’s methods of Expression reflect physical reality—all bodies are vulnerable to sudden damage just as Dickens can dismember a body suddenly either with the stroke of a pen or by delaying its complete description. We see that on this level the body is at it most vulnerable and is damaged by methods of expression rather than by narrative. Dickens here plays most intensively with the literalization of metaphor, linguistically insisting that if a head appears around a doorway we can no longer assume that a body will follow. The novels are filled with dictionally decapitated heads and severed limbs, but through the use of humour and by reanimating these members Dickens ensures that his style elicits not simply a reaction of horror in his readers but elicits a response to the grotesque—a strong instinctual attraction to his work which is rooted in the body, not in the intellect. This dissertation concludes that the body’s vulnerability is not only a continual presence in Dickens’s novels but is an under-examined yet fundamental element in what makes his writing style distinctive and what makes his work continually popular.

[Truncated abstract] It has frequently been reported that individuals with elevated anxiety vulnerability impose threat-congruent interpretations upon emotionally ambiguous stimuli. A common hypothesis is that such threat-congruent interpretations contribute causally to the intensity and frequency of the anxiety elevations experienced by vulnerable individuals. However, no direct evidence has been provided to support this hypothesis. Empirically evaluating this theoretical position was the goal of the series of empirical studies described in this thesis. The approach employed here involved first, systematically and specifically manipulating interpretive bias, and second, assessing the consequences of such manipulations for anxiety vulnerability as assessed by individual differences in the intensity of emotional reaction to a subsequent stressor. This research was conducted in two phases. The studies in Phase 1 were designed to permit the development of training tasks, capable of inducing group differences in interpretive bias. The employed approach to such interpretive training involved the modification of priming tasks previously used to assess interpretive bias. In each trial of such priming tasks, homograph primes with both threatening and non-threatening meanings are first presented, followed by targets which, on different trials, are related to their threatening or to their non-threatening meanings. Participants are required to respond to identify each target, using the prime as a cue. In order to create interpretive training tasks capable of manipulating interpretive bias, contingencies were introduced into such priming task methodologies, such that the targets were related to differentially valenced prime meanings for different groups of participants. For the threat training group, the targets presented during training were always related to the threatening meanings of the 2 homograph primes, making it advantageous for these participants to interpret the primes in a threat-congruent fashion, with the intention of inducing a threat-congruent interpretive bias. For the non-threat training group, the targets in training were always related to the non-threatening meanings of the ambiguous primes, making it advantageous to interpret the primes in a non-threat-congruent fashion, with the intention of thus encouraging a non-threat-congruent interpretive bias. The success of these training procedures in modifying interpretive bias was then assessed in subsequent, non-contingent versions of these priming procedures

Positive community-police relations, which are based on mutual trust, are key to equitable and just policing. Use of force that is perceived as unfair and biased can quickly undermine relations between the police and the public. In an attempt to understand what psychological factors contribute to police use of force decisions and potentially racially biased use of force application, this study proposed masculinity threat as an important psychological factor that influences police behavior. Masculinity threat occurs when a man's status as a man is threatened, and threats to masculinity are often associated with increased aggression and dominance as a way of restoring the threatened status. Policing is a male-dominated field, and because most victims of officer use of force are men, the current research examines how threats to male police officers' masculinity, including verbal and physical manifestations of threat, contribute to officer force against civilians. Past research has explored how high levels of trait masculinity threat (as measured by the Male Gender Role Stress scale; Goff, Martin, & Gamson-Smiedt, 2012) in police officers is associated with higher levels of force against racial minority suspects, however, no such research has examined state level masculinity threat (e.g., in the moment threats) as they occur in real world police-suspect interactions. Focusing on understanding the associations between use of force and state level masculinity threat, it was predicted that officers who have their masculinity explicitly and publicly threatened by male suspects will use more force against suspects compared to interactions where no such masculinity threat has occurred. It was also predicted that minority suspects who threaten officers' masculinity will receive more force than White suspects. To test these hypotheses, reporting officers' (RO) narratives of use of force interactions (excluding lethal force) from a large police department on the West Coast were coded and analyzed. Contrary to the hypotheses, results suggest that masculinity threat within an officer-suspect interaction may relate to lower levels of average officer force and higher number of sequences (e.g., back and forth exchanges) between suspect and officer. While results are in the opposite direction of the hypotheses, they provide new information regarding the association between personal threats to officer manhood and their subsequent actions. Specifically, results suggest that masculinity threat has a more complicated relationship with force than previously predicted and future research would do well to investigate a potential interaction effect of trait level and state level masculinity on police use of force decisions. Several other areas of further research are outlined, such as the need to examine other suspect-level and officer-level variables such as age and tenure. Overall, the results of this study suggest the need for continued clarifying research.
