Abstract

We measured an essentially normal pedestal effect using stationary gaussian targets and slowly moving pedestal gratings. Since these conditions greatly reduce the information provided by the pedestal, we question whether uncertainty about the stimulus can be the main cause of the pedestal effect.

摘要

我们使用静止的高斯目标和缓慢移动的基座光栅测量了基本正常的基座效应。由于这些条件极大地减少了由基座提供的信息，我们质疑刺激的不确定性是否可能是基座效应的主要原因。
