Abstract

The contribution of afterimages to spatial-frequence adaptation was studied by comparing a number of different fixation paradigms designed to maximize of minimize afterimages. While it is clear that adaptation is not an afterimage artifact, nevertheless afterimages are produced at low spatial frequencies and can considerably distort the results of adaptation experiments unless steps are taken to eliminate them.

摘要

通过比较旨在最大化或最小化后像的多种不同注视范式,研究了后像对空间频率适应的影响。虽然很明显适应不是后像伪像,但低空间频率下会产生后像,并且除非采取措施消除它们,否则后像会严重扭曲适应实验的结果。
