Predicting perceptual decision biases from early brain activity.
Perceptual decision making is believed to be driven by the accumulation of sensory evidence following stimulus encoding. More controversially, some studies report that neural activity preceding the stimulus also affects the decision process. We used a multivariate pattern classification approach for the analysis of the human electroencephalogram (EEG) to decode choice outcomes in a perceptual d...
متن کاملDecision Biases and Decision Support Systems Development
The view of decision-making that has informed most decision support systems research has been Simon’s process theory. Further, the majority DSS work has focussed on the choice phase of Simon’s model of decision-making. Decision bias theory does not focus on the choice process but considers the possibility of systematic and persistent errors in all phases of judgement and decision-making. Decisi...
متن کاملElapsed decision time affects the weighting of prior probability in a perceptual decision task.
Decisions are often based on a combination of new evidence with prior knowledge of the probable best choice. Optimal combination requires knowledge about the reliability of evidence, but in many realistic situations, this is unknown. Here we propose and test a novel theory: the brain exploits elapsed time during decision formation to combine sensory evidence with prior probability. Elapsed time...
متن کاملThe Limits of Deliberation in a Perceptual Decision Task
While it is commonly assumed that decisions taken slowly result in superior outcomes, is it possible that optimal decision making does not always require sacrificing speed? For odor categorization decisions, it was previously shown that rats use <300 ms regardless of difficulty, but these findings could be interpreted as a tradeoff of accuracy for speed. Here, by systematically manipulating the...
متن کاملChanging in the Reaction Time Causes the Confidence Matching in Group Decision Making
Introduction: Others’ decision could constantly affect our decisions. There are numerous studies which revealed this effect properly. The social influence could affect most of the decision parameters, especially the confidence. Recently, an interesting study showed that participants tend to match their confidence to each other while they preserve their decision accuracy in a group decision mak...
