Wow thank you so much for this video Dr.Atchison. You saved my day and more. I really like how you organized the content and how you explain things so clearly. I was lost from reading Kanowitz text. Thank you so much
Hi Kristin. I've a question regarding the Signal Detection Theory. Could you please explain how the threshold itself is determined before measuring decision bias? Do we first measure the threshold using various methods (e.g., method of constant stimuli) and only then proceed with measuring the bias?
That is a good question. I would look at empirical research that uses signal detection, they will describe the specifics of their methods in detail. However, there is a lot known about the general level of perception (for example human hearing ranges from 20-20,000 hz) so you would want your stimuli in that range to be perceptible.

Are these constants' values also valid in Stevens Power Law or are there other values? Where I can find constant values for Stevens Power Law?
This was so helpful. Thank you Dr. Kristin
good stuff
Nice voice and intonation

Are you asking how the fixed low intensity stimulus is set?
exactly.

thank you ❤
plz come teach at UGA, we need you.
This is the best explanation for psychophysics I have seen! thank you!
