What is the minimal intensity of stimulation necessary to trigger a muscle contraction?
threshold stimulus
What is a pain threshold?
A pain threshold is the point at which a person starts to feel discomfort or pain from a stimulus. It is the level of intensity at which a person perceives a sensation as painful. Different individuals have different pain thresholds.
What conclusions can you draw about the relationship between a muscle's workload and its threshold of stimulation?
As the muscle workload increase, its threshold of stimulation increases.
Just noticeable difference is a constant proportion of the intensity of an initial stimulus is this weber's law?
Yes, that's correct. Weber's law states that the just noticeable difference (JND) between two stimuli is proportional to the intensity of the initial stimulus. This means that the difference needed to perceive a change in stimulus intensity remains constant regardless of the initial intensity level.

What is the differences between the absolute threshold and the differential threshold Which is more important to marketers?
The absolute threshold is the minimum intensity of stimulus required to be perceived. In other words, it is the intensity amount which is needed to detect the difference between nothing and something. It is the lowest level at which an individual can experience a sensation.On the other hand, the minimal difference that can be detected between two stimuli is called the difference threshold or the j.n.d. (just noticeable difference)The main difference between the two concepts is that the differential threshold is a relative concept. Whereas the absolute threshold deals with whether or not a stimulus can be perceived, the differential threshold refers to the intensity difference needed between two stimuli before people can perceive that the stimuli are different.The marketing implication of absolute threshold is that consumers will only perceive a marketing stimulus when it is higher than absolute threshold. In other words, if images or words in a commercial are too small, consumer's sensory receptors will not ve activated and the stimulus will not be perceived. The differential threshold also has very important marketing applications Difference Threshold: The difference threshold, also known as the just noticeable difference (jnd), is the minimum difference in stimulation that a person can detect 50 percent of the time. We experience the difference threshold as a just noticeable difference. For example, let's say I asked you to put your hand out and in it I placed a pile of sand. Then, I add tiny amounts of sand to your hand and ask you to tell me when you notice any change in the overall weight. As soon as you can detect any change in the weight, that difference between the weight of the sand before I added that last bit of sand and the amount of sand after I added it, is the difference threshold.The absolute threshold is the minimum intensity of stimulus required to be perceived.

What is meant by coding of stimulus intensity?
Threshold
Smallest change in sensation that a person can detect is?
threshold.
The term just noticeable difference is synonymous with?
difference threshold
What is jnd?
Just Noticeable Difference (JND) The minimal difference that be detected between two similar stimuli is called the differential threshold, or just noticeable difference. In the field of psychophysics, that branch of experimental psychology that studies sensation and perception, a jnd is the amount that something must be changed for the difference to be noticeable, defined to mean that the change is detectable half the time
The minimum amount of stimulation required to tell the difference between two stimuli is called the?
An absolute threshold is the smallest detectable level of a stimulus, whereas the just-noticeable difference is the smallest detectable change in two stimuli levels.
What is the minimal stimulus needed to elicit a muscle contraction is called?
Threshold Stimulation
