Answer:
<u><em>They found that the cats that had observed the performance </em></u><u><em>30 times</em></u><u><em> had performed significantly better than the ones that only observed it </em></u><u><em>15 times.</em></u>
Explanation:
According to my research, in 1944 <u><em>Herbert and Harsh</em></u> did a set a various experiments. They believed that an animal can substantially benefit from watching a more evolved animal perform a certain task. They also believed that there is a strict correlation between the amount of times that they view the more evolved animal perform the task with how well they can perform the same task.
After comparing the behavior of cats that had observed a model perform an act 30 times with cats that had observed only 15 performances. <u><em>They found that the cats that had observed the performance </em></u><u><em>30 times</em></u><u><em> had performed significantly better than the ones that only observed it </em></u><u><em>15 times.</em></u>
