Psych Learning Flashcards
Law of effect
Actions followed by favorable consequences will tend to be repeated
Operant behavior
Operates (acts) on environment; voluntary behavior
Skinner box (Operant chamber)
A chamber with a bar or key that an animal manipulates to obtain a food or water reinforcer
Reinforcer
Any event or stimulus that, when the following response, strengthens its occurrence
Positive reinforcement-Incentives (add something good)
Addition of a favorable stimulant- money; TV privileges
Negative reinforcement- Taking away something bad
Removal of an aversive stimulus; seat belt buzzer-immediately put on seatbelt; getting a headache- taking an Advil
Punishment
The aversive event that, when following a response, decreases the behavior’s occurrence
Positive punishment- adding something bad
Administration of an aversive stimulus- spanking; speeding tickets
Negative punishment- taking away something good
Withdrawal of a desirable stimulus- timeout; revoked license
Negative reinforcement vs. Punishment
Punishment by application vs. removal
Negative reinforcement is NOT a punishment
Continuous Reinforcement
Reinforcing the desired response each time it occurs
Partial/intermittent Reinforcement
Reinforcing a response only part of the time
Fixed ratio
Reinforces a response only after a specified number of responses
The faster you respond the more rewards you get
Variable Ratio
Reinforces a response after an unpredictable number of responses
Very hard to extinguish because of unpredictability
Fixed Interval
Reinforces a response only after a specified time has elapsed
The response occurs more frequently as the anticipated time for reward draws near
