Abstract:
This dissertation provides support for the expansion of traditional definitions of information, to include experiential forms of data (e.g., attitudes, opinions, and familiarity related to the task at hand) that have typically been treated as nonsubstantive and therefore were often been excluded from most of the previous research on group information sharing. This study also examines how to effectively intervene when groups develop norms that privilege or suppress then mentioning of certain types of information during decision-making discussions.

Abstract:
Fatigue is a state that, although researched for many years, is still not completely understood. Alongside this lack of a general understanding of fatigue is a lack of knowledge on the processes involved in the regulation of fatigue. The existing theories relating to regulation are focussed on mental effort regulation, suggesting that performance outcomes are co-ordinated by effort regulation that functions by making alterations to physiological processes and strategic adjustments at a cognitive level in response to cognitive demands and goals. Since fatigue is a multi-dimensional construct wi

Background: Pathological gambling is a pervasive and destructive behavioral disorder in which individuals lose control over their gambling behavior, leading to severe personal, social and financial consequences. Current animal models of gambling behavior such as the rodent gambling task (rGT) are useful tools with which to evaluate choice behavior. However, they are limited in their insights into gambling behavior in that they mostly model dimensions of economic decision-making, but not the salient cues intrinsic to human gambling paradigms.
