講題:DO WE HAVE FREE WILL? - Pre-existing Brain States Predict Decision Making
個人CV:謝伯讓老師 (臺灣大學心理學研究所副教授)
演講摘要: It is well known that unconscious information processing can influence human behaviour and cognition, including decision-making. However, the neural basis of such unconscious influence remains unclear. Here we propose an approach that localizes the essential parts of the brain that are unconsciously involved in human decision-making. We focus on the unconscious neural basis of decision-making by searching for neural antecedents that occur before and predict human decisions. Our approach goes beyond conventional paradigms that only look for the “neural correlates” of decision-making, and will grant us the ability to localize candidate brain areas that are the “neural causes” of decision-making but not merely “neural correlates” or “neural consequences”. Specifically, we investigate whether pre-stimulus brain states (i.e. baseline brain states right before stimulus presentation and decision-making) can affect evaluative decisions and their locations/means of exerting an influence if one exists. Our date show that evaluative decisions can be predicted by human subjects’ pattern of fMRI signals across a widely distributed network of regions in the frontal lobes before the stimuli are presented.
