Cards

Term
Associative Learning
Definition
Learning that certain events (a response and its consequences in operant conditioning) occur together.
Term
Continuous reinforcement
Definition
Any event following a response that increases the probability or strength of the preceeding behavior.
Term
Intrinsic motivation
Definition
motivation that is driven by an interest or enjoyment in the task itself, and exists within the individual rather than relying on any external pressure.
Term
Extrinsic motivation
Definition
the performance of an activity in order to attain an outcome, which then contradicts intrinsic motivation
Term
Latent learning
Definition
Learning that occurs but is not apparent until there is an incentive to demonstrate it.
Term
Law of effect
Definition
Thorndike's principle that behaviors followed by favorable consequences become more likely.
Term
Learned helplessness
Definition
The condition of a human or animal that has learned to behave helplessly.
Term
Learning
Definition
A relatively permanent change in an organism's behavior due to experience.
Term
Negative reinforcement
Definition
Increasing behaviors by stopping/reducing negative stimuli.A negative reinforcer is any stimulus that, when removed after a response, strengthens the response.
Term
Operant Behavior
Definition
Behavior that operates on the environment, producing consequences.
Term
Operant chamber
Definition
A chamber containing a bar/key that an animal can manipulate to obtain a food/water reinforcer.
Term
Operant conditioning
Definition
A type of learning in which behavior is strengthened if followed by a reinforcer/ diminished if followed by a punisher.
Term
Partial reinforcement
Definition
Reinforcing a response only part of the time: results in slower acquisition of a response but much greater resistance to extinction than continous reinforcement.
Term
Primary reinforcer
Definition
An innately reinforcing stimulus, such as one that satisfies a biological need.
Term
Secondary reinforcer
Definition
A stimulus that gains its reinforcing power through its association with a primary reinforcer.
Term
Schedules of reinforcement
Definition
4 schedules of partial reinforcement.
Including Fixed-interval schedule, Fixed Ratio, Variable-interval, variable ratio, and Shaping.
Term
Fixed-Ratio schedule(FR)
Definition
In operant conditioning, A reinforcement schedule that reinforces a response only after a specified # of responses.
Term
Variable-Ratio Schedule(VR)
Definition
In OC, A reinforcement schedule that reinforces a response after an unpredictable # of responses.
Term
Fixed-Interval Schedule(FI)
Definition
In OC,A reinforcement schedule that reinforces a response only after a specified time has elapsed
Term
Variable-Interval Schedule(VI)
Definition
In OC, A reinforcement schedule that reinforces a response at unpredictable time intervals.
Term
Shaping
Definition
An operant conditioning procedure in which reinforcers guide behavior toward closer and closer approximations of the desired behavior
Term
Edward Thorndlike
Definition
His study on learning process led to the theory of connectionism. Worked on Law of effect.
His work would be a major influence to B.F. Skinner.
Term
B.F. Skinner
Definition
English Major.New behavior technology.
Designed the operant chamber(skinner box).
Discovered shaping and reinforcments.
