In this video I explain how signal detection theory relates to psychophysics and the study of absolute and difference thresholds. I also explain how response criteria play a role in signal detection theory and the possibility of type I and … Read More
Psychophysics!
In this video I introduce psychophysics and explain the difference between the absolute threshold and the difference threshold (or just noticeable difference). I also discuss the difficulties of measuring our sensitivity to stimulation and provide a simple demonstration of Weber’s … Read More
What is Psychophysics?
My apologies to those of you hoping to read about physics gone mad; the truth is that psychophysics is actually the study of our sensitivity to stimuli of different strengths. This is generally done by attempting to measure different types of … Read More
