6.3 & 6.3.1 Flashcards
Operant conditioning
A type of learning in which behavior is strengthened if followed by a reinforcer or diminished if followed by a punisher
Operant behavior
Behavior that operates on the environment producing consequences
Law of effect
Thorndike’s principle that behaviors followed by favorable consequences become more likely and that behaviors followed by unfavorable consequences become less likely
Operant chamber
In operant conditioning Research A chamber (also known as a skinner box) containing a bar see that an animal can manipulate to obtain a food or water reinforcer; attached devices record the animals rates of bar pressing or key pressing
Shaping
And operant conditioning a procedure in which reinforcers guide behavior toward closer and closer approximations of the desired behavior
Discriminative stimulus
In operant conditioning A stimulus that elicts A response after association with reinforcement (in contrast to related stimuli bit associated with reinforcement)
Reinforcer
In operant conditioning any the event that strengthens the behavior it follows
Positive reinforcement
Increasing behaviors by presenting positive stimuli such as food. A positive reinforcer is any stimulus that when presented after a response strengthens the response
Negative reinforcement
Increasing behaviors by stopping or reducing negative stimuli such as shock. A negative reinforcer is any stimulus that when removed after a response strengthens the response (note: negative reinforcement is not a punishment)
Primary reinforcer
An innately reinforcing stimulus such as one that satisfies a biological need
Conditioned reinforcer
A stimulus that games it’s reinforcing power through its association with a primary reinforcer; also known as secondary reinforcer
Continuous reinforcement
Reinforcing the desired response every time it occurs
Partial (intermittent) reinforcement
Reinforcing a response only part of the time; results and slower acquisition of a response but much greater resistance to extinction than does continuous reinforcement
Fixed-ratio schedule
In operant conditioning A reinforcement schedule that reinforces a response only after a specified number of responses
Variable-ratio schedule
In operant conditioning a reinforcement schedule that reinforces a response after an unpredictable number of responses
