Assessing Animals’ Preferences: Concurrent Schedules of Reinforcement

Matching and Maximizing in Concurrent Schedules

In a recent article, Staddon and Motheral derived a mathematical model of responding in concurrent variable-interval-variable-interval schedules. According to this model, maximization of overall reinforcement rate predicts the operant matching law. However, Staddon and Motheral's derivation ignores a fundamental aspect of the concurrent schedule contingency. There are two simultaneously availab...

Update schedules of sequential dynamical systems

Sequential dynamical systems have the property, that the updates of states of individual cells occur sequentially, so that the global update of the system depends on the order of the individual updates. This order is given by an order on the set of vertices of the dependency graph. It turns out that only a partial suborder is necessary to describe the global update. This paper defines and studi...

Concurrent drinking by pigeons on fixed-interval reinforcement schedules.

Three experienced pigeons were exposed to at least ten consecutive 100-min sessions on each of three food-reinforced fixed-interval (FI) schedules: FI 50-sec, FI 100-sec and FI 200-sec. Water was freely available. Drinking was largely confined to the first third of each fixed interval, and the mean sessional water intake was directly related to the food-reinforcement rate for each animal. The a...

Guided Testing of Concurrent Programs Using Value Schedules

Testing concurrent programs remains a difficult task due to the non-deterministic nature of concurrent execution. Many approaches have been proposed to tackle the complexity of uncovering potential concurrency bugs. Static analysis tackles the problem by analyzing a concurrent program looking for situations/patterns that might lead to possible errors during execution. In general, static analysi...
