Percebos

Percebos is a term used in some discussions within cognitive science and philosophy of mind to denote the smallest units of perceptual content that can be distinguished and reported. A percebo (plural percebos) is intended as a discrete, modality-specific element—such as a single color sample, a pure-tone pitch, or a tactile feature—that can be combined with others to form fuller representations of objects or scenes. The idea is akin to a percept or a qualia token, but the label percebo emphasizes discrete chunks of sensory information rather than holistic experience.

Usage and status: The term is not widely standardized; different authors may define percebos differently, and some prefer other terms. In some accounts, percebos are proposed as the elementary units from which perceptual binding and object representations are constructed, potentially corresponding to transient neural representations in early sensory areas or working memory buffers.

Theoretical role: Percebos are used to model how rapid, serial perception could be assembled from discrete pieces, offering a framework for explaining phenomena such as change detection, attentional limits, and the accuracy of reported sensory details. They intersect debates about whether perception is best understood as continuous or discrete and about the granularity of conscious content.

Criticisms: Critics argue that the notion of objectively discrete perceptual units risks oversimplifying perceptual richness and that empirical verification is difficult. Alternatives include continuous or multi-scale representations and probabilistic encoding in neural populations.
