Decision Making Cognitive Styles, Information Processing Time, and Value Relevance of Voluntary Disclosure: A Brunswick Leans Model Approach

Voluntary disclosure result to increasing value relevance because of increasing decisionmaking accuracy. In this study to evaluate the different decision making styles a cognitiveand behavioral model are used. The field of this research in terms of territory subject to the "theory of information overload" and Processing "Brunswick Leans Model" is placed in behavioral accounting. This research has a quasi-experimental method. Research period are in 2012. For purposes of this study, experimental group (176 respondents) and control group (158 respondents) were classified in the four dominant styles: directive, analytical, conceptual, and behavioral. Also, investors in terms of the brain dominant style and cognitive complexity so as uncertainty about the tolerance level were classified. Evidence was presented that shows left-brain dominant style to spend more time on average to process information. Also, Analytical decision-making style than other styles as well as spend more time to process information. Indeed High complexity styles have Accuracy after Voluntary disclosure presented. But we didn’t find any relationship between Voluntary disclosure and other styles decision-making accuracy. So, we can result Voluntary disclosure don’t have respected to increasing value relevance.
