| A | B |
| operant conditioning | Learning that is strengthened when behavior is followed by positive reinforcement |
| reinforcement | A stimulus or event that follows a response and increases the frequency of that response |
| primary reinforcer | A stimulus, such as food or warmth, that has reinforcement value without learning |
| secondary reinforcer | A stimulus that increases the probablility of a response because of its association with a primary reinforcer |
| positive reinforcer | An encouraging stimulus that increases the frequency of a behavior when it is presented |
| negative reinforcer | An unpleasant stimulus that increases the frequency of behavior when it is removed |
| schedule of reinforcement | A timetable for when and how often reinforcement for a particular behavior occurs |
| continuous reinforcement | The reinforcement of a desired response every time it occurs |
| partial reinforcement | A type of conditional learning in which only some of the responses are reinforced |
| shaping | In operant conditioning, a procedure in which reinforcement guides behavior toward closer approximations of the desired goal |
