Reinforced variability decreases with approach to reinforcers.
Journal of Experimental Psychology: Animal Behavior Processes, 1996Anticipation of rewards had different effects on operant variability than on operant repetition. We reinforced variable (VAR) response sequences in groups of rats and pigeons and repetitive (REP) response sequences in separate groups. A fixed number of variations or repetitions was required per food reinforcer (e.g., fixed-ratio 4).

The material most commonly used for the fabrication of complete dentures is poly (methyl methacrylate) (PMMA). This material is not ideal in every respect and it is the combination of virtues rather than one single desirable property that accounts for its popularity and usage.

Reinforcement, or the strengthening of reproductive isolation in response to hybridization costs, is a case in which natural selection directly contributes to the origin of new species. From its conception, reinforcement has enjoyed alternate periods of enthusiasm and rejection, in which powerful verbal arguments identified obstacles that were ...

Secondary Reinforcement as a Function of Reinforcement Scheduling
Psychological Reports, 1956In the present study, albino rats were given discrimination training in a modified Skinner Box. During this training several schedules of SD—SR pairings were presented; differential effects of this training were measured during extinction, which also involved a further scheduling of the R—Sr pairings.

SECONDARY REINFORCEMENT AS A FUNCTION OF THE NUMBER OF REINFORCED TRIALS1
Child Development, 1961The purpose of this study was to observe the effects of varying habit strength sustained through secondary and primary reinforcers upon extinction behavior of children in an operant situation. A few studies (I, 3, 4, 6) have investigated the relation between number of training trials and extinction with secondary reinforcement of rats.

Longitudinal Reinforcement Limits for Fiber-Reinforced Polymer Reinforced Concrete Members
ACI Structural Journal, 2017Adequate ductility is an important issue for fiber-reinforced polymer (FRP) reinforced concrete (RC) members because of the brittle behavior of FRP bars and concrete. FRP reinforcement in the tension side needs to be sufficient to prevent the brittle rupture of the FRP bars and attain the ultimate compressive strain in concrete in the compression side.

Reinforcement Schedule and the Durability of A Secondary Reinforcer
The Psychological Record, 1965To investigate the possibility of PRE upon an Sr, a neutral stimulus (light) was paired with primary reinforcement (candy) on three different reinforcement schedules, with no response required of S. The light was presented for 18 trials. On reinforced trials, candy appeared simultaneously with the light.

Speciation has a central place in evolution, linking genetic processes within populations to the generation of biological diversity. The formation of new species must involve the evolution of barriers to gene flow within existing species, but how these barriers arise remains a problem.

The Psychological Record, 1975
Variants of the differential reinforcement paradigm were investigated as a function of both present schedule of reinforcement and past reinforcement history. Results suggest that such differential reinforcement procedures are effective in both increasing new responses and decreasing old responses. Reinforcement history was found not to be a significant
