The effect of the primary reinforcement in the SFRC corbels was the most sensitive and a slight increase of primary reinforcement up to 1.
15% primary reinforcement (cross-sectional area of primary reinforcement over cross section of the corbel), and also subjected only to horizontal loading.
Only the ratio of cross section in respect of primary reinforcement was varied in this series.
Although the delay to primary reinforcement clearly is important, can we assume that a delayed reinforcer is always ineffective?
Delayed Primary Reinforcement Effects in Concurrent Schedules
The first is that the stimuli are merely discriminative for a given rate of primary reinforcement and without any conditioned reinforcing strength (Baum, 1973, p.
Moreover, their findings were inconsistent with the molar notions that choice behavior is a function only of the primary reinforcement presented at the end of each cycle and that terminal-link stimuli are solely discriminative.
The non-contingent reinforcement component allowed staff to be paired with primary reinforcement
, thereby establishing staff presence and social praise as secondary reinforcers while discontinuing the pairing of staff with demands, as in previous settings.
A] is the time between the appearance of stimulus A and primary reinforcement, and where T is the overall time between reinforcer presentations.
Perhaps the most common procedure for assessing choice is the concurrent-chains procedure, as depicted in Figure 1, where responding to concurrent initial-link schedules (the choice phase) is reinforced by the presentation of two mutually exclusive terminal-link schedules (the outcome phase), completion of which leads to primary reinforcement.
Effect of primary reinforcement schedule on secondary reinforcement strength with continuous secondary reinforcement during training.
Secondary reinforcement strength as a function of schedule of primary reinforcement.
My colleagues and I have hypothesized that for some children, problem behaviors like aggression, self-injury, and property destruction occur not because they directly produce primary reinforcement
, but rather because these destructive behaviors increase the probability of reinforcement for mands (Fisher et al.
