Unconscious influences on decision making: A critical review

if they exist at all – have limited and narrow effects. 1.1 A framework for the components of decision making. Our first step in examining the role of the unconscious in theories of decision making is to propose a framework for thinking about how decisions could be influenced by unconscious processes. The framework is ...

Decisions under Uncertainty: Probabilistic Context Influences

Mar 30, 2005 ... Many decisions are made under uncertainty; that is, with limited information about their potential consequences. Previous neuroimag- ing studies of decision making have implicated regions of the medial frontal lobe in processes related to the resolution of uncertainty. However, a different set of regions in ...
