PSY-3215 Study Guide - Quiz Guide: Detection Theory, Absolute Threshold, Limen
Document Summary
When fechner founded psychophysics he was trying to find/make a connection between the physical world and the mental world. He wanted to know how these two world were related to each other and how they interacted with one another. The absolute threshold was very important to understand this connection. This threshold was the point where the mental and the physical connected; where a physical stimulus first was able to be psychologically detected: how do you determine the absolute threshold, using the method of limits, the. To determine absolute threshold via the method of limits, an observer is presented with a range of stimulus (above and below threshold). These stimuli can be presented in ascending or descending order. The point at which the observer first hears the stimulus (if it"s in ascending order) is the absolute threshold; the point where the observer cannot hear the stimulus anymore (if it"s in descending order) is the absolute threshold.
