Feature extraction and feature interaction
Frank W. Ohl, Henning Scheich · Behavioral and Brain Sciences · 1998
The idea of the orderly output constraint is compared with recent findings about the representation of vowels in the auditory cortex of an animal model for human speech sound processing (Ohl & Scheich 1997). The comparison allows a critical consideration of the idea of neuronal “feature extractors,” which is of relevance to the noninvariance problem in speech perception.
