Dear Profs. Brainard & Pelli,
I am an undergraduate student of cognitive psychology laboratory at
Sophia university in Japan.I am writing a graduation thesis about
hemispheric asymmetry in detection task. To do this task, I need to
measure a threshold of an individual subject and I decided to use
contrast threshold demo to measure subject's threshold.But since I am
not pshychophysician, I can not tell what kind of method is used in the
Quest procedure.I have looked up some books and I thought the method
used in the Quest procedure is Maximum-likelihood procedure.Is my
thought correct? If not, I would be greatful if you can tell me what
method is used. I have to hand my graduation thesis in december.So I do
not have much time left, please help me out.
I apologize for asking such a basic question.
Yours Kenichiro Yamaoka
