摘要:

知觉竞争,即冲突的感官信息导致交替感知,对相关认知功能至关重要,长期以来吸引了研究者的关注。尽管取得了一定进展,但最近的研究揭示了在各种竞争情境中我们的理解存在局限性和不一致。我们开发了一个统一的物理框架,其中感知经历一个连续的相变过程,涵盖不同的多状态竞争。我们通过识别感知状态之间的主导切换路径,并量化平均感知持续时间、切换频率和不同感知的比例,揭示了知觉竞争的底层机制。我们通过分析平均非平衡流和熵生产率,揭示了非平衡动力学和热力学的底层机制,而相关时间序列的不可逆性反映了知觉竞争的非平衡机制,并将热力学结果与神经电生理实验联系起来。我们的框架提供了对大脑感知的全局和物理理解,可能超越认知科学或心理学,但体现了与更广泛领域如决策制定的联系。

英文摘要:

Perceptual rivalry, where conflicting sensory information leads to alternating perceptions crucial for associated cognitive function, has attracted researcher's attention for long. Despite progresses being made, recent studies have revealed limitations and inconsistencies in our understanding across various rivalry contexts. We develop a unified physical framework, where perception undergoes a consecutive phase transition process encompassing different multi-state competitions. We reveal the underlying mechanisms of perceptual rivalry by identifying dominant switching paths among perceptual states and quantifying mean perceptual durations, switching frequencies, and proportions of different perceptions. We uncover the underlying nonequilibrium dynamics and thermodynamics by analyzing average nonequilibrium flux and entropy production rate, while associated time series irreversibility reflects the underlying nonequilibrium mechanism of perceptual rivalry and link thermodynamical results with neuro-electrophysiological experiments. Our framework provides a global and physical understanding of brain perception, which may go beyond cognitive science or psychology but embodies the connection with wider fields as decision-making.
