Question

Carlos wants to demonstrate Weber’s law. What is the BEST way for him to do this? A. Draw two lines of the same length using depth cues and see if people see them differently. B. Let babies crawl to the end of a low table to see if they stop before they fall off the edge. C. Offer people five different foods to taste and see if they can identify them without looking. D. Give people weights to hold then add more weight to see if they sense the difference.

Answer 1

The BEST way for Carlos to demonstrate Weber’s law is by giving people weights to hold and gradually increasing the weight to see if they can sense the difference based on Weber's law. The correct answer is option D.

Step-by-step explanation:

The BEST way for Carlos to demonstrate Weber’s law is option D: Give people weights to hold then add more weight to see if they sense the difference.

According to Weber's law, the just-noticeable difference in a stimulus, such as weight, is proportional to the magnitude of the original stimulus. By giving people weights to hold and gradually increasing the weight, Carlos can test if they can sense the difference between the weights based on Weber's law.

For example, if Carlos starts with a 1-pound weight and adds an additional 0.1 pounds, according to Weber's law, people should be able to notice the difference. However, if Carlos adds 0.01 pounds, the difference may not be noticeable. Testing different weights and increments will help Carlos determine if the findings adhere to Weber's law.
