 Results of Analyzer-Revealing Experiments

Show Summary Details


This chapter summarizes available evidence from the four kinds of near-threshold analyzer-revealing experiments presented in previous chapters — adaptation, summation, uncertainty, and identification — for each of the seventeen pattern-vision dimensions along which multiple analyzers might exist. The effects of several factors, like age of observer and psychophysical procedure are also described. For each dimension, the chapter asks whether multiple analyzers exist on that dimension, and if they do, asks further questions: what is the analyzers' bandwidth? Are their outputs labeled? Are their outputs probabilistically independent or correlated? Is there inhibition among them? Occasional references are given in the course of the summary, but the majority of the references are to be found in a list of references at the end of the chapter organized by the type of analyzer-revealing experiment and by the patterns dimensions studied.

Keywords: bandwidth; analyzers; channels; pathways; detectors; correlation; inhibition; spatial frequency; orientation; motion
