The principle that two stimuli must differ by a constant proportion for their difference to be perceived is known as?
"Ernst Weber noted that for people to really perceive a difference, the stimuli must differ by a constant "proportion" not a constant "amount."
What else can I help you with?
Definition: In a direct proportion y = kx, the number k is called the constant of ______.?
proportion
What is the direct proportion?
Two variables, X and Y, are said to be in direct proportion if X/Y is a constant. Equivalently, Y = cX for some constant c.
In a direct proportion y kx the number k is called the constant of .?
It is the constant of proportionality.
Who scientist verified law of constant proportion?
Joseph Proust.
What does constant of proportion mean?
If two variables are in direct relationship then the ratio of the two variables is known as the constant of proportion between them. In algebraic form, if X and Y are the two variables, then direct proportionality implies that Y = cX and c is the constant of proportionality.
What is the principal that two stimuli must differ by a constant proportion for their difference to be perceived is known as?
Weber's Law
What is the definition of weber's law?
Weber's law states that the just noticeable difference between two stimuli is proportional to the magnitude of the stimuli. In other words, the change in stimulus needed to detect a difference is a constant ratio of the original stimulus level.
What is the principles of proportion?
The principle of constant proportions state that the ratio of major salts in samples of seawater from various places is a constant. It is a law stating that every pure substance always contains the same elements combined in the same proportions.

In a direct proportion y kx the number k is called the constant of .?
It is the constant of proportionality.
What is the definition for constant of proportionality?
The state of being in proportion.
What is the direct proportion formula?
x and y are in direct proportion if there is some positive constant c such that y = cx
Who scientist verified law of constant proportion?
Joseph Proust.
Give an example of direct proportion?
The Circumference of a circle is directly proportional to the diameter. The constant of proportion is 'pi = 3.141592....'. Another one is force is directly proportional to mass. The constyant of proportion is acceleration.
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 does constant of proportion mean?
If two variables are in direct relationship then the ratio of the two variables is known as the constant of proportion between them. In algebraic form, if X and Y are the two variables, then direct proportionality implies that Y = cX and c is the constant of proportionality.
