Threshold means the limit values in which an individual perceives or interprets something.
Threshold stimulus science definition. Generally a threshold stimulus is the smallest amount of stimulation or force that is needed to initiate a response. A physiological example can be. For example there is a minimum value at which someone can perceive a certain stimulus.
In psychophysics sensory threshold is the weakest stimulus that an organism can detect. An agent action or condition that elicits or accelerates a physiological or. Such stimuli can be internal or external.

The threshold stimulus is the weakest stimulus that could generate an action potential in a neuron. Methods have been developed to measure thresholds in any of the senses. Threshold stimulus synonyms threshold stimulus pronunciation threshold stimulus translation english dictionary definition of threshold stimulus.
Stimulus threshold refers to the minimum intensity required from a stimulus to produce a response from a human or an animal. It is also the point where a human or an animal first senses and responds to a stimulus. Threshold is the lowest level of a stimulus that causes a person to experience pain.
Internal stimuli come from inside an organism pain and hunger are internal stimuli. This value is a threshold. A dolorimeter is used to measure pain threshold and a stimulus is applied until the person first shows a response which is then taken as the threshold.
