Question

What is the intensity of the stimulus that can be detected at least half the times called?

Answer 1

The correct answer is - Absolute threshold or Absolute Limen.

A threshold is defined as a change occurring in a stimulus which is detectably different almost half of the times.

An absolute threshold or absolute limen is a detectable sensory threshold which has a minimum or the least amount of a stimulus required so that it is reliable and can be detected at 50% of the time. It is the minimum quantity of stimulus energy which can be detected.

Answer 2

In psychophysics, which is apparently more a branch of psychology than material science, the stimulus intensity alludes to the force of a tactile info with respect to as far as possible or time when the information is distinguishable half of the time. A typical case of its utilization would be in hearing tests.

Stimulus intensity is encoded in two ways: 1) frequency coding, where the terminating rate of tangible neurons increments with expanded power and 2) populace coding, where the quantity of essential afferents reacting increments (additionally called RECRUITMENT).
