Studies of decision making in small human groups reveal behavior that illustrates both advantages and disadvantages to social feedback. ABSTRACT | To investigate the influence of information about fellow group members in a constrained decision-making context , we develop four two-armed bandit tasks in which subjects freely select one of two options (A or B)(More)
—With a principled methodology for systematic design of human-robot decision-making teams as a motivating goal, we seek an analytic, model-based description of the influence of team and network design parameters on decision-making performance. Given that there are few reliably predictive models of human decision making, we consider the relatively well(More)
The mechanisms that govern human learning and decision making under uncertainty have been the focus of intense behavioral and, more recently, neuroscientific investigation. Substantial progress has been made in building models of the processes involved, and identifying underlying neural mechanisms using simple, two-alternative forced choice decision tasks.(More)
In this thesis, we investigate human decision making dynamics in a series of simple perceptual decision making tasks. The level of caution with which a human subject responds to stimuli is of central interest, since it influences the speed and accuracy of responses. We study the role of caution parameters in models of cognitive control processes. We first(More)
