In a classroom experiment, students were asked to place one paper clip in each hand. They were then instructed to add paper clips to the left hand until they were certain that the clips in the left hand weighed more than the paper clips in the right hand. The class average was seven paper clips before a difference in weight was observed. Students were then asked to follow the same procedure with psychology text books. The instructor is demonstrating:
a. a comparison of absolute thresholds.
c. Webers law.
d. stimulus generalization.
I'm almost sure that it's c-Weber's law,but also thinking about a.
Thank's for any help!
