When The Stimulus Intensity Is Increases

When the intensity of the stimulus is increased, the size of the action potential does not become larger. Rather, the frequency or the number of action potentials increases.

Rather, as stimulus intensity is increased, the probability that an observer will say that the stimulus is visible increases. This relationship between the probability of a response and the stimulus intensity is called a psychometric function.

An active individual gives up task performance and becomes inactive with probability p per unit time: Variations in stimulus intensity are caused by task performance which reduces stimulus intensity and the natural increase of demand irrespective of whether or not the task is performed. The stimulus intensity s is calculated as formula (5.7):

What happens when you increase stimulus intensity?

Rather, as stimulus intensity is increased, the probability that an observer will say that the stimulus is visible increases. This relationship between the probability of a response and the stimulus intensity is called a psychometric function.

How does stimulus intensity affect reaction time?

Abstract. Previous research indicates that response force increases with stimulus intensity in simple reaction time (SRT) tasks. This result contradicts the common view that the perceptual system activates the motor system via a punctate go signal of fixed size.

What is stimulation intensity?

Threshold: the minimum intensity of a stimulus that is required to produce a response from a sensory system.

What does the intensity of a stimulus determine for a neuron?

Stimulus intensity determines experience-dependent modifications in neocortical neuron firing rates.

What is the relationship between the frequency of stimulation and force of contraction?

The force–frequency relationship refers to the phenomenon in which the isometric force produced by a muscle increases with the frequency of activation, resulting in a sigmoidal curve which plateaus at the high frequencies.

What is muscle stimulation frequency?

Neuromuscular electrical stimulation (NMES), used interchangeably with electrical stimulation (ES), is typically provided at higher frequencies (20-50 Hz) expressly to produce muscle tetany and contraction that can be used for “functional” purposes and can be found in literature as early as 1964 [4].

What happens to the strength of contraction when the stimulus frequency is increased?

Your answer: As the stimulus frequency increases, the muscle force generated by each successive stimulus will increase. There will be a limit to this increase.

How does frequency of stimulation affect muscle contraction?

Higher intensity and higher frequency induce stronger muscular contractions, but also a stronger decline in force and thus quick-setting muscle fatigue.
