Apr 19, 2018 · Threshold is the magnitude or intensity of a stimulus that leads to its detection or response 50% of the time. Learn about different types of thresholds, such as auditory, excitatory, and renal, and see examples.

For hearing, the absolute threshold refers to the smallest level of a tone that can be detected by normal hearing when there are no other interfering sounds present. Whether you can detect a the ticking of a clock in a quiet room would be an example.
For vision, the absolute threshold refers to the smallest level of light that a participant can detect. Determining the absolute threshold for vision might involve measuring the distance at which a participant can detect the presence of a candle flame in the dark. For example, imagine that you are a participant in a psychology experiment. You are p...
For odors, the absolute threshold involves the smallest concentration that a participant is able to smell. An example of this would be to measure the smallest amount of perfume that a subject is able to smell in a large room. Even the time of day that data is collected can have an influence on the absolute threshold. Environmental factors such as p...
The amount of force required for you to detect the feeling of a feather lightly brushing your arm is an example of the absolute threshold for touch. When it comes to touch, the level of stimulation required to detect the stimulus can vary dramatically depending upon the part of the body that is being touched.
While the absolute threshold is often thought of purely in terms of sensation and perception, factors such as our expectations, motivations, and thoughts influence whether we can detect a stimulus. For example, if you expect to hear a noise, you might be more likely to pick up on it at lower levels than if you weren't expecting it. Researchers have...
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. The difference threshold is also known as the just noticeable difference. Some examples include: 1. How ...
(A threshold is the lowest point at which a particular stimulus will cause a response in an organism.) Read More. In human eye: Measurement of the threshold. An important means of measuring a sensation is to determine the threshold stimulus—i.e., the minimum energy required to evoke the sensation.
A threshold is the minimum amount of stimulation needed to start a neural impulse (you know, the electrical impulses that travel throughout your body carrying important information).
In psychology, a threshold is the minimum point of stimulus intensity required to elicit a perceptual or behavioral response. It is a fundamental concept in sensory and perceptual psychology, helping to define and measure the limits of human and animal responses to various external stimuli.
The authors propose a process-neutral definition of threshold that allows for graded perception and activation throughout the system. Thresholds correspond to maximum stimulus intensities such that the distribution of mental states does not differ from that when an appropriate baseline stimulus is presented.
