1
00:00:04.000 --> 00:00:08.200
There are different ways of reinforcing.

2
00:00:08.200 --> 00:00:12.200
There is positive reinforcement and negative reinforcement.

3
00:00:12.200 --> 00:00:22.000
To remember the difference between these two types of reinforcement, it helps to understand how these terms are used.

4
00:00:22.000 --> 00:00:32.000
Positive means to add or to get something.  Negative means to take away or remove something.

5
00:00:32.000 --> 00:00:38.500
In the example of the girl cleaning her room, the child was given something desirable, money.

6
00:00:38.500 --> 00:00:45.000
Her receiving the money is meant to be positive; it makes cleaning the room more likely.

7
00:00:45.000 --> 00:00:50.000
This is positive reinforcement as indicated by the plus sign.

8
00:00:50.000 --> 00:00:57.500
Try another example.  You go to the beach and get sunburned.  It is painful.

9
00:00:57.500 --> 00:01:06.000
Next time you go to the beach, you put on sunscreen. This prevents the pain. Pain is removed.

10
00:01:06.000 --> 00:01:16.500
The removal is what is meant by negative; the absence of pain might make you more likely to use sunscreen in the future.

11
00:01:17.000 --> 00:01:23.000
This is negative reinforcement as indicated by the minus sign.
