Changeover delay and concurrent schedules
… the effects of changeover delay (COD) on concurrent variable-interval schedule performance. The first experiment involved manipulations of the relative reinforcement rates on the two schedules presented on two separate keys while holding the COD constant over a series of COD durations from …

Effects of Concurrent Fixed Interval-fixed Ratio Schedules of Reinforcement on Human Responding.
… in generating human performances sensitive to concurrent schedules of reinforcement. Five participants produced performances observed to be under temporal and ratio control of concurrent fixed interval-fixed ratio schedules. Two aspects of interaction between FI and FR schedules were …

Matching Equation: Teacher Rates of Praise and Reprimands
… (GME) further into the classroom, given the concurrent schedules available for teacher behavior. This study examined the effects of a contrived contingency to alter the rates of teachers’ praise and reprimand statements. Further, this study assessed the extent of biases and sensitivity to …

The Matching Law and Schedule: Induced Drinking
… a lever for food. Food was made available by a concurrent variable-interval variable-interval reinforcement schedule. One schedule alternative provided one pellet of food every 90 seconds on the average. The other alternative was varied over a range from 30 to 180 seconds. A drinking tube was …

A RATE COMPARISON MODEL OF CONCURRENT SCHEDULE PERFORMANCE
<p>A rate comparison model of concurrent schedule performance and foraging is proposed. The model is a molecular equalizing theory of matching, based on results from optimal foraging theory and corresponding data from behavioral ecology. It state that animals leave one concurrent alternative for …

Negative Reinforcement by Timeout from Avoidance: The Roles of Discriminative Cues, Shock-Frequency Reduction, and Response-Effort Reduction
… is not firmly established. Rats responded on concurrent schedules of avoidance and timeout. Pressing the right lever postponed shocks according to a schedule with a response-shock interval of 30 s and a shock-shock interval of 5 s, and pressing the left lever produced 2-min timeouts according …

EFFECTS OF RESPONSE FREQUENCY CONSTRAINTS ON LEARNING IN A NON-STATIONARY MULTI-ARMED BANDIT TASK
An n-armed bandit task was used to investigate the trade-off between exploratory (choosing lesser-known options) and exploitive (choosing options with the greatest probability of reinforcement) human choice in a trial-and-error learning problem. In Experiment 1 a different probability of …

Concurrent schedule performance of possums: a comparison of two models
… brushtail possums (Trichosurus vulpecula) under concurrent variable-interval schedules of reinforcement. In the first experiment the lever pressing of six possums resulted in intermittent access to a barley/carob mixture under four pairs of variable-interval schedules. In most respects, the …

An Investigation into Establishing (Motivating) Operations
… when the hens were subsequently exposed to FR schedules with a low response requirement in Experiment 3.2, they did not respond consistently. This indicated that the level of restriction was insufficient to motivate responding and this finding, combined with the difficulty of obtaining ethical …

The Effects of Alternative Contingencies on Instruction Following.
The purpose of this experiment was to evaluate the effects of alternative contingencies on instruction following by an ABA design. Three college students consistently pressed keys 1-5-3 and 4-8-6 in the presence of the written instruction "Press 153" or "Press 486." During condition A, the …

Food preferences and demand in the brushtail possum (Trichosurus vulpecula)
… the demand for these foods were measured under concurrent progressive-ratio (PR) and fixed-ratio (FR) schedules of reinforcement. In Experiment 3, the same six food types were used and every possible food pair (30 pairs in total) was presented to six possums in concurrent PR and FR 30 schedules. …
