The important aspect of the history involves a correspondence between an arbitrary event and a currently effective reinforcer Conditioned Reinforcer An arbitrary event that becomes able to increase the frequency of an operant Unconditioned Reinforcer Reinforcing stimulus that has acquired its properties as a function of species history (aka biological reinforcer) New-Response Method First, a nonreinforcing stimulus is associated with a reinforcing event (sound of feeder is followed by food). Afterwards, this stimulus is shown to increase the frequency of some operant behavior- Often results in short-lived effects Chain Schedule of Reinforcement Two or more simple schedules (CRF, FI, VI, VR), each of which is presented sequentially and is signaled by an arbitrary stimulus. Only the final or terminal link of the chain results in unconditioned reinforcement Tandem Schedule A schedule of reinforcement is which unconditioned reinforcement is programmed after completing two or more schedules, presented sequentially without discriminative stimuli Homogeneous Chains Operant chains in which the topography or form of response is similar in each component Heterogeneous Chains Operant chains that require a difference response for each link Backward Chaining The idea is to begin training at the end of the sequence. That is, you first teach the behavior in the final link of the chain- 2 - Factors affecting conditioned reinforcement 1. Preference for conditioned reinforcer increases with the frequency of the unconditioned reinforcement 2. Alternative schedule is preferred over fixed schedule with the same payoff 3. Establishing operations increase the effectiveness of a conditioned reinforcer 4. The longer the delay between a discriminative stimulus and unconditioned reinforcement, the less effective it is as a conditioned reinforcer New-Response Method Involves pairing a discriminative stimulus such as a click with unconditioned reinforcement Established- Response Method An operant that produces unconditioned reinforcement is accompanied by a discriminative stimulus, just prior to reinforcement SS-account of conditioned reinforcement Theory that conditioned reinforcement is based on classical conditioning Discriminative-...
