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 type II errors. Finally, I consider applications of signal detection … 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 Law, which is that the difference threshold relates to proportions … 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 thresholds. Absolute threshold refers to the minimum amount of stimulation necessary for … Read More
