This is useful in determining which general human engineering principles, for example, design, or selection and training, are likely to be effective in a particular situation.
WebEvery sense has an absolute threshold. The absolute threshold is defined as the lowest intensity at which a stimulus can be detected (recently, signal detection theory has offered a more nuanced definition of absolute threshold: the lowest intensity at which a stimulus will be specified a certain percentage of the time, often 50%).
