Perceptual decision making is the act of choosing one option or course of action from a set of alternatives on the basis of available sensory evidence. Thus, when we make such decisions, sensory information must be interpreted and translated into behaviour. Neurophysiological work in monkeys performing sensory discriminations, combined with computational modelling, has paved the way for neuroimaging studies that are aimed at understanding decision-related processes in the human brain. Here we review findings from human neuroimaging studies in conjunction with data analysis methods that can directly link decisions and signals in the human brain on a trial-by-trial basis. This leads to a new view about the neural basis of human perceptual decision-making processes.
知觉决策是指根据可得的感官证据，从一组备选方案中选择一个选项或行动方案的行为。因此，当我们做出此类决策时，必须对感官信息进行解读并转化为行为。对执行感官辨别任务的猴子进行的神经生理学研究，结合计算建模，为旨在理解人类大脑中与决策相关过程的神经影像学研究铺平了道路。在此，我们结合数据分析方法来回顾人类神经影像学研究的结果，这些方法能够在逐个试次的基础上直接将人类大脑中的决策与信号联系起来。这引发了对于人类知觉决策过程神经基础的全新观点。
