TL;DR
The design may be viewed as an analogue of central place foraging, and it appeared that delay mediated the effect of the other independent variables on the average number of pellets accumulated before they were eaten.
Abstract
Rats could accumulate food pellets by responding on one lever, and then gain access to them by responding on a second lever N times (experiment 1), by ceasing to respond on the first lever for D seconds (experiment 2), or by making a single, vigorous response of force W on the second lever (experiment 3). The design may be viewed as an analogue of central place foraging. As N (distance), D (time), or W (effort) increased, load (the average number of pellets accumulated before they were eaten) also increased. It appeared that delay mediated the effect of the other independent variables. A simple model of central place foraging was shown to accommodate the data.

The general conclusion is that the simple models so far formulated are supported are supported reasonably well by available data and that the author is optimistic about the value both now and in the future of optimal foraging theory.

An optimal foraging model is tested which predicts how a predator should exploit patchily distributed prey and the results are consistent with the predictions of the model.

Four pigeons were trained to peck at either of two response-keys, and the relative rate at which each pigeon pecked to obtain a secondary reinforcer equalled the Relative rate of primary reinforcement in its presence.

Whether or not an animal may gain a selective advantage by employing different search methods in different seasons in a fluctuating environment is explored, and emphasis is laid here on the energy cost of locomotion during foraging and its effect on the foraging time.

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, which consistent with that predicted by the harmonic rather than by the arithmetic rates of reinforcement.
