Document Summary
Skinner says that there are 2 types of reinforcement: positive reinforcement occurs when a response is strengthened b/c it is followed by the presentation of a rewarding stimulus. Negative reinforcement occurs when a response is strengthened b/c it is followed by the removal of an aversion (unpleasant) stimulus. Escape learning: where an organism acquires a response that decreases or ends some aversive stimulation. Ex. leaving a party where you were getting picked on by your peers, turning on the ac to get rid of heat. Def: where an organism acquires a response that prevents some aversive stimulation from occurring. Ex. avoiding parties b/c you were concerned about being picked on. In ~, a fear response is acquired through classical conditioning and an avoidance response is maintained by operant conditioning. Def: occurs when an event following a response weakens the tendency to make that response. Opposite procedure of negative reinforcement that yields opposite effects on behaviour.
