Acquisitioni. Learning the linkii. Aka shapingiii. Continuous reinforcement 1. Every instance of a desired response is reinforced2. Used during shaping onlyiv. What Reinforcer should be used?II. Types of Reinforceri. Primary Reinforcer1. Satisfies biological needa. EX: food and water2. Diminishing returnsii. Secondary reinforcers1. Learned associations with primary reinforcersa.

Reinforce after unpredictable time intervalsi. Ex: checking status updates in FBV. Different schedules of intermittent reinforcementa. Random reinforcementi. Reinforce at random timesii. Creates bizarre behaviorb. Phases of operant conditioningi. Extinction1. More difficult in OC than CC2. Stopping rewardsa. Surge in responding followed by slow, gradual
