Evolving Perceptual Categories
This paper uses sim-max games to model perceptual categorization with the goal of answering the following question: to what degree should we expect the perceptual categories of biological actors to track properties of the world around them? I will argue that an analysis of these games suggests that the relationship between real-world structure and evolved perceptual categories is mediated by su...
متن کاملEvolving Perceptual Categories **Draft, do not cite**
Hume’s scepticism was based, in part, on what he believed to be an inability of human observers to ever go beyond their perceptual experiences. How can an observer determine the veridicality of perception when her only access to the external world is mediated by perception itself? A related question may be asked about not the qualities of perception, but about the perceptual categories of biolo...
متن کاملPerceptual thresholds and tonal categories
A discussion of tonal categories relating to pitch perception discrimination thresholds focuses on the differences between pitch perception per se and the perception of tonal timing. In the light of several experimental studies on the perception of tonal timing categories in different languages, it is hypothesized that the perception of level tones can be related to the highly acute psychophysi...
متن کاملThe Structure of Perceptual Categories
When presented with a small set of sample objects, human observers have the striking capacity to induce a more general class. Generalization can even proceed from a single object ("one-shot categorization"). The inference is apparently guided by the principle that a good categorical hypothesis is one in which the observed object would be a typcal, "non-accidental," or generic example; this idea...
متن کاملPerceptual categories for spatial layout.
The central problems of vision are often divided into object identification and localization. Object identification, at least at fine levels of discrimination, may require the application of top-down knowledge to resolve ambiguous image information. Utilizing top-down knowledge, however, may require the initial rapid access of abstract object categories based on low-level image cues. Does objec...
