Law of effect and Operant Conditioning

Edward Thorndike

1. Put a cat in a Puzzle box and observe the cats behavior towards escaping to get food.

2. The law of effect is when responses are closely followed by satisfaction and become firmly attached to the situation and therefore more likely to happen again when the situation is repeated. Though, if the situation is followed by trouble, the connections to the situation will become weaker and the behavior of response is less likely to occur when the situation is repeated.

3. The law of exercise means that you have to practice in order to be good at something and the more you practice the best you will be at it

B.F. Skinner

1. operant conditioning: reinforcement and punishment change our behavioral tendencies.

2. Reinforcement is consequence that causes the behavior to occur with greatear frequency.

3. Punishment is consequence that causes a behavior to occur with less frequency.

4. Positive reinforcement: occurs when a behavior response is followed by a stimulus that is appetitive or rewading, increasing the frequency of that behavior. In the skinner box experiment, a stimulus such as food or sugar solution can be delivered when the rat engages in a target behavior, such as pressing a lever.
Negative reinforcement: occurs when a behavior response is followed by the removal of an aversive stimulus, thereby increasing that behavior's frequency. In the Skinner box experiment, negative reinforcement can be a loud noise continuously sounding inside the rat's cage until it engages in the target behavior, such as pressing a lever, upon which the loud noise is removed.
Positive punishment: occurs when a behavior response is followed by a stimulus, such as introducing a shock or loud noise, resulting in a decrease in that behavior.
Negative punishment: occurs when a behavior responseis followed by the removal of a stimulus, such as taking away a child's toy following an undesired behavior, resulting in a decrease in that behavior.
