Causal uncertainty refers to the lack of confidence in one’s ability to understand causal relations in the social world (Weary & Edwards, 1994). Relative to people with low causal uncertainty, individuals with high causal uncertainty exhibit enhanced self-regulation performance following a social interaction (Jacobson, Papile, Passey, & Boucher, 2006). The current studies investigated the potential mechanisms underlying this relationship, and the role of self-esteem. Study 1 investigated whether the social or nonsocial nature of the depleting task and expectations about the need for future self-control could account for the relationship between causal uncertainty and self-regulation (N = 181). For the social task, high causally uncertain participants’ self-regulation performance was consistent across expectations for future self-control regardless of participant self-esteem. In contrast, low causally uncertain participants’ performance improved with increasing instructions to conserve energy for future tasks but only for participants with lower self-esteem. For low causally uncertain participants with higher self-esteem, self-regulation performance decreased with increased expectations for future self-control. In the nonsocial condition, the findings did not differ by self-esteem. Learning that the future task involved self-control and that the initial task was depleting were both associated with increases in self-regulation for high causally uncertain participants. In contrast, self-regulation abilities did not differ for low causally uncertain participants upon learning that the future task involved self-control and marginally decreased when they learned that the initial task was depleting. Study 2 examined whether or not self-presentation could account for the relationship between causal uncertainty and self-regulation abilities (N = 88). Higher causal uncertainty was associated with better self-regulation performance, but self-presentation goals did not moderate this relationship. Self-esteem did not influence self-regulation performance in this study. Study 3 investigated whether or not an accuracy goal could account for the relationship between causal uncertainty and self-regulation abilities (N = 112). For participants with lower self-esteem, high causally uncertain participants’ self-regulation performance was consistent regardless of the goal manipulation; whereas low causally uncertain participants’ performance improved with instructions to create accurate impressions of their partner. In contrast, for participants with higher self-esteem, self-regulation did not differ by causal uncertainty or goal conditions. / Thesis (Ph.D, Psychology) -- Queen's University, 2009-08-28 14:40:08.139

High causally uncertain (CU) individuals experience lingering doubts about their ability to determine the causes of social events (Weary & Edwards, 1994). Furthermore, these people tend to perceive their interactions and conversational partners more negatively (Boucher & Jacobson, 2009). However, the reasons for these negative reactions remain unclear. Therefore, the purpose of the current set of studies was to explore two possible explanations for these reactions. Specifically, in three studies, I examined if insufficient uncertainty reduction or negative interpersonal expectations mediate the relationship between causal uncertainty and liking for a recent acquaintance. In Study 1 (N = 114), participants engaged in a brief unstructured dyadic conversation, whereas in Study 2 (N = 176), they engaged in three conversations with different partners. Finally, in Study 3 (N = 220), I examined the effects of temporarily activating causal uncertainty beliefs during initial interactions. As predicted, causal uncertainty was negatively associated with liking and uncertainty reduction. In Studies 1 and 2, high CU participants reported more uncertainty about themselves and their partner, and less liking than did low CU participants. Although chronic levels of causal uncertainty in Study 3 were not associated with liking or uncertainty reduction, participants who reported more current feelings of uncertainty also reported more uncertainty about themselves and their partner, and less liking. More importantly, uncertainty reduction fully mediated the effect of causal uncertainty on liking in Study 1 and partially mediated the effect of current uncertainty feelings on liking in Study 3. Therefore, high CU people’s negative social perceptions appear to stem, at least in part, from an inability to reduce their social uncertainty during initial interactions. In contrast, the relationship between causal uncertainty and interpersonal expectations remains unclear. Although causal uncertainty (as well as current uncertainty feelings) in Studies 1 and 3 were not associated with negative interpersonal expectations, high CU participants in Study 2 did report more negative expectations for their first conversation relative to low CU participants. Furthermore, although causal uncertainty was positively related to rejection sensitivity, rejection sensitivity was unable to account for the causal uncertainty effects on liking. / Thesis (Ph.D, Psychology) -- Queen's University, 2009-07-24 15:13:51.847

Causation and foreseeability in private law The issue of this thesis is the causation and foreseeability in private law. The aim of this diploma thesis is to provide comprehensive view of both presented legal institutes and their significance in law. This thesis especially focuses on detailed analysis of procedure of proving the causation and introduces the most significant issues arising from this proceeding. Introduction is aimed at the function and especially at detailed definition of the term causality not only in law, but also in the area of natural sciences. It defines the term foreseeability in the same way. Moreover, it defines conditions that considerably affect foreseeability. Consequently, it aims to provide the relation between foreseeability and causation. This thesis also deals with the significance of causation from the perspective of legal liability. In this context, it mentions the issue of causally relevant conditions. On this basis, this paper tends to its core which consists of detailed analysis of methods of proving the factual causation. Universally accepted method of proving factual causation is considered the 'conditio sine qua non' test. However, this test is found to be ineffective in cases of causal uncertainty. Therefore there are more effective instruments for equitable...
