Questions What Causes Phobias? How Can You Control Behavior?
4
What Causes Phobias? A phobia is an irrational fear. Phobias can be caused by classical conditioning. A previously neutral stimulus becomes associated with another stimulus that normally causes a particular response.
5
What Causes Phobias? Without any learning, the Unconditional Stimulus (US) causes the Unconditional Response (UR). A Conditional Stimulus (CS) becomes associated with the US. After learning, the CS causes a Conditional Reponse (CR).
6
What Causes Phobias? Some stimuli naturally cause fear responses. If a previously neutral stimulus (CS) becomes associated with a fear-provoking stimulus, a fear-response (CR) can result from the CS. Generalization and Discrimination
7
What Causes Phobias? Classical conditioning can also reduce phobias. Extinction Spontaneous recovery
8
How Can You Control Behavior? Operant Conditioning allows us to learn from the consequences of our behaviors. Behavior can be controlled by altering the consequences.
9
How Can You Control Behavior? Reinforcement increases a behavior. Punishment decreases a behavior.
10
Add Something Remove Something Increase Behavior Decrease Behavior positive reinforcement negative punishment positive punishment negative reinforcement
11
Misconception Alert! Negative reinforcement is not a type of punishment.
12
How Can You Control Behavior? New behaviors can be taught through shaping: successive approximations. Timing is crucial.
13
How Can You Control Behavior? Behavior is less likely to be extinguished if reinforced intermittently – Fixed Ratio – Variable Ratio – Fixed Interval – Variable Interval
