Neural Signatures of Evidence Accumulation Encode Subjective Perceptual Confidence Independent of Performance.
Confidence is an adaptive computation when environmental feedback is absent, yet there is little consensus regarding how perceptual confidence is computed in the brain. Difficulty arises because confidence correlates with other factors, such as accuracy, response time (RT), or evidence quality. We investigated whether neural signatures of evidence accumulation during a perceptual choice predict subjective confidence independently of these factors. Using motion stimuli, a central-parietal positive-going electroencephalogram component (CPP) behaves as an accumulating decision variable that predicts evidence quality, RT, accuracy, and confidence (Experiment 1, N = 25 adults). When we psychophysically varied confidence while holding accuracy constant (Experiment 2, N = 25 adults), the CPP still predicted confidence. Statistically controlling for RT, accuracy, and evidence quality (Experiment 3, N = 24 adults), the CPP still explained unique variance in confidence. The results indicate that a predecision neural signature of evidence accumulation, the CPP, encodes subjective perceptual confidence in decision-making independent of task performance.
期刊介绍:
Psychological Science, the flagship journal of The Association for Psychological Science (previously the American Psychological Society), is a leading publication in the field with a citation ranking/impact factor among the top ten worldwide. It publishes authoritative articles covering various domains of psychological science, including brain and behavior, clinical science, cognition, learning and memory, social psychology, and developmental psychology. In addition to full-length articles, the journal features summaries of new research developments and discussions on psychological issues in government and public affairs. "Psychological Science" is published twelve times annually.
