Today in class we'll be learning about psychophysics and different types of thresholds. To that end, we'll be trying a couple of online tests for sensory ability.
Absolute Threshold - Vision - This module introduces you to how absolute thresholds are measured. You won't get a score, but you will try out some practice test items.
Difference Threshold (JND) - Adaptive Pitch Test - determines your sensitivity to detecting differences between two presented tones. This is a difference threshold test because the test attempts to determine what degree of difference is necessary.
