An experimenter is studying the relationship between hunger and aggression.
00:05
She measures aggression by counting the number of times a participant will hit a punching bag.
00:11
So for the experimenter, aggression is equal to the number of times the bag is hit.
00:21
So number of times the bag is punched.

00:37
There are two types of definition that we use in psychology.

00:50
The other type that is not shown here is the theoretical.
00:56
So the other type is theoretical...
