Absolute threshold -- the minumum intensity of a stimulus that one can detect. Difference threshold -- the minimum difference in intensity between two stimuli that one can detect.
Threshold is defined as the he change in a stimulus that is detectably different 50% of the time. If the change is from no stimulation at all, that threshold stimulus is called the absolute threshold. Otherwise the threshold is a difference threshold, because it measures the threshold for detecting the difference between stimuli: a stimulus before and after it is changed. The size of the stimulus change required for detection is called the threshold.
