Question

Weber's Law of just noticeable differences (difference threshold) states that:

a) The noticeable difference between two stimuli is proportional to the magnitude of the stimuli.
b) The noticeable difference between two stimuli is constant regardless of the magnitude of the stimuli.
c) The noticeable difference between two stimuli depends solely on the observer's mood.
d) The noticeable difference between two stimuli is inversely proportional to the magnitude of the stimuli.

Answer 1

Weber's Law states that the noticeable difference between two stimuli is proportional to the magnitude of the stimuli. The difference threshold increases as the magnitude of the stimuli increases.

Step-by-step explanation:

Weber's Law of just noticeable differences states that the noticeable difference between two stimuli is proportional to the magnitude of the stimuli. In other words, the larger the stimuli, the greater the difference needed to be noticed. This law suggests that there is a constant ratio between the difference threshold and the original stimulus.

For example, let's say you have a bag of rice that weighs 1 pound. According to Weber's Law, you would need to add a certain amount of weight for someone to notice a difference. If you added 0.1 pounds to the bag, it might not be noticeable. But if you added 0.5 pounds, it would likely be noticeable. The difference threshold increases as the magnitude of the stimuli increases.
