How Awareness Changes the Relative Weights of Evidence During Human Decision-Making

Human decisions are based on accumulating evidence over time for different options. Here a simple question is asked: How is the accumulation of evidence affected by the level of awareness of the information? The influence of awareness on decision-making is examined using combined behavioral methods and magneto-encephalography (MEG). Participants were required to make decisions by accumulating evidence over a series of visually presented arrow stimuli whose visibility was modulated by masking. Behavioral results and neural recordings are examined. URL:[http://www.plosbiology.org/article/info%3Adoi%2F10.1371%2Fjournal.pbio.1001203].
