摘要：

The ability of observers to discriminate between stimuli differing in orientation was measured using low contrast, foveally viewed stimuli. Detection and discrimination performance were measured simultaneously. A model is presented which permits bandwidths of orientation-tuned mechanisms to be estimated from the data. In a group of five observers, half-amplitude bandwidths varied from 10 degrees to 20 degrees.
