In a two-link, concurrent-chain schedule, pigeons' pecks on each key during the initial link occasionally produced a terminal link, during which only that key was operative. Responses in the terminal link were reinforced with food on either fixed-interval or variable-interval schedules. In one experiment, relative amount of responding in the initial link(More)

Two variables often confounded in fixed-ratio schedules are reinforcement frequency and response requirement. These variables were isolated by a technique that yoked the distributions of reinforcements in time for one group of pigeons to those of pigeons responding on various fixed-ratio schedules. The contingencies for the yoked birds were then manipulated(More)

The matching law may be viewed either as an empirical generalization, and therby subject to disproof, or as part of a system of equations used to define the utility ("value") of a reinforcer. In the latter case it is tautologous, and not subject to disproof within the defining context. A failure to obtain matching will most often be a signal that the(More)

Pigeons were trained on a two-link concurrent chain schedule in which responding on either of two keys in the initial link occasionally produced a terminal link, signaled by a change in the color of that key and a darkening of the other. Further responding on the lighted key was reinforced with food according to a fixed-interval schedule. For one of the(More)
In 2005 Psychological Science, the flagship journal of the Association for Psychological Science, began their current practice of asking contributors to compute the statistic prep in lieu of the traditional p-value. In a polemic comprising five Fits we argue that prep is misnamed, commonly miscalculated, misapplied outside a narrow scope, and its large(More)
The operant contingency remains the most powerful and flexible single technology for the production and control of purposive behavior. The immediate aim of this paper is to examine the conceptual and empirical adequacy of the operant contingency as the basis for a science of purposive behavior. My longer-term goal is to improve the effectiveness of operant(More)
This paper presents a comparison of the inductive switching losses between a 1200 V SiC MOSFET half bridge power module with anti-parallel SiC schottky barrier diodes (SBD) versus the same power module package utilizing only the intrinsic body diode of the SiC MOSFETs. SBDs can significantly reduce switching losses by reducing the reverse recovery losses(More)
Circuit protection devices and power distribution units for future More Electric / All Electric Aircraft (MEA/AEA) power systems require an increased level of control and intelligence along with fast-acting protection mechanisms. The trend towards utilizing solid-state power electronics for system-level protection of MEA/AEA systems has increased due to the(More)
