Threshold is the level at which a stimulus first causes a person to feel pain. Tolerance is the maximum amount of pain a person is able to cope with. The pain threshold is the particular level at which a stimulus causes a person to start to experience pain.
The threshold will vary depending on what the stimulus is; for instance, there will be different pain threshold values for temperature and pressure. Pressure, temperature or electrical signals are often used as the stimulus and the pain level recorded. The minimum stimulus to cause pain would be the pain threshold. The pain threshold is influenced by genetics; researchers have found polymorphisms in particular genes that play a role in influencing the threshold.
The genes discovered to impact threshold include those that code for transient receptor potential A subtype 1 channels, fatty acid hydroxylase, opioid receptors, and catechol-O-methyltransferase,. Children have a low pain threshold compared to adults but the threshold changes as they grow older. Gender is also a factor, with females having a lower threshold, possibly for evolutionary reasons or due to biological factors. Pain threshold does not vary as much among people as does tolerance to pain.
Pain tolerance describes the highest levels of pain a person can tolerate. This is quite variable from one individual to another, for a particular painful stimulus. Tolerance to painful stimuli can be measured using a dolorimeter and adjusting the intensity of stimuli to reach a maximum level, which would be the tolerance level.

When people are younger, they are able to detect energy levels at lower levels. They require greater stimulation to detect these same stimuli when they are older. The absolute threshold serves as an important tool for researchers studying the capabilities and limitations of human sensation and perception. One important thing to remember is that researchers distinguish between the ability to detect a stimulus and the ability to tell the difference between stimulus levels.
The absolute threshold should not be confused with the difference threshold, which is the smallest possible detectable difference between two stimuli. Ever wonder what your personality type means?
