报告简介

Despite advances in techniques for exploring reciprocity in brain-behavior relations, few studies focus on building neurocognitive models that describe both human EEG and behavioral modalities at the single-trial level. Here, we introduce a new integrative joint modeling framework for the simultaneous description of single-trial EEG measures and cognitive modeling parameters of decision-making. As specific examples, we formalized how single-trial N200 latencies and centroparietal positivities (CPPs) are predicted by changing single-trial parameters of various drift-diffusion models (DDMs).

传统的DDM模型难以考虑试次内的认知变化，Amin Ghaderi等人提出了一个新框架来同时描述EEG测量和决策的认知建模参数。传统DDM假设决策偏好是固定的，但漂移率很容易受到刺激和噪音的影响，在不同的试次中是变化的。该新框架可以更准确地反映决策偏好在不同条件下的变化。
