absolute threshold in a sentence

The absolute threshold is the minimum amount of stimulation required for a person to detect the stimulus 50 percent of the time. The difference threshold is the smallest difference in stimulation that can be detected 50 percent of the time.

Absolute threshold is the minimum stimulus intensity required to activate a sensory receptor 50% of the time.

1. The absolute threshold is defined statistically, often as an average of all obtained hearing thresholds.
2. It was at the absolute threshold of audibility, where it might have been real or imagined.
3. The lowest equal-loudness contour represents the quietest audible tone the ” absolute threshold of hearing “.

A difference threshold is the minimum required difference between two stimuli for a person to notice change 50% of the time (and you already know where that “50% of the time” came from). The difference threshold is also called just noticeable difference, which translates the concept more clearly.

The threshold of hearing is generally reported as the RMS sound pressure of 20 μPa (micropascals) = 2×10−5 pascal (Pa). It is approximately the quietest sound a young human with undamaged hearing can detect at 1,000 Hz.

Limitation of Weber’s law in the auditory system Weber’s law does not hold at perception of higher intensities. Intensity discrimination improves at higher intensities.

For the weight of magnitude, I = 5.0 kg, the increment threshold I = 0.5 kg. The ratio of I/I for both instances (0.2/2.0 = 0.5/5.0 = 0.1) is the same. This is Weber’s Law. Weber’s Law states that the ratio of the increment threshold to the background intensity is a constant.

Terms in this set (15) Why did Gustav Fechner’s definition of absolute threshold need to be modified? A) Alertness and the testing situation can influence an individual’s thresholds. Because his definition of the absolute threshold did not differ significantly from the difference threshold.

The stimuli that are not enough to reach de absolute threshold and therefore are below to it are called subliminal stimuli.
