TLDR
The present results, together with related research, suggest that the ratio of time spent in two activities equals the ratios of the "values" of the activities.Abstract:
When pigeons' standing on one or the other side of a chamber was reinforced on two concurrent variable-interval schedules, the ratio of time spent on the left to time spent on the right was directly proportional to the ratio of reinforcements produced by standing on the left to reinforcements produced by standing on the right. The constant of proportionality was less than unity for all pigeons, indicating a bias toward the right side of the chamber. The biased matching relation obtained here is comparable to the matching relation obtained with concurrent reinforcement of key pecks. The present results, together with related research, suggest that the ratio of time spent in two activities equals the ratio of the "values" of the activities. The value of an activity is the product of several parameters, such as rate and amount of reinforcement, contingent on that activity.read more

Control over sensory change versus sensory state preference in sensory contingent bar pressing.
TL;DR: Sixteen rats selected as high responders in a sensory contingent bar pressing situation, were studied when they had free access to four different sensory states and preferences proved to be a relatively weak predictor of choice behaviour.
Estimates of energy expenditure in women and a biofeedback device for weight loss
TL;DR: Using nanofiltration membranes for the recovery of phosphorous with a second type of technology for recovery of nitrogen is suggested to be a viable method for weight loss in women.

Regularities in responding during performance of a complex choice task

TL;DR: Models of response production and selection that take into account the time between individual responses, probabilities of transitions between response options, periodicity within response sequences, and individual differences in response dynamics can clarify the mechanisms that drive behavioral adjustments during operant conditioning.

Relative and absolute strength of response as a function of frequency of reinforcement
TL;DR: The present experiment is a study of strength of response of pigeons on a concurrent schedule under which they peck at either of two response-keys and investigates output as a function of frequency of reinforcement.

Choice and delay of reinforcement
TL;DR: The relative frequency of responding at each key was shown to match the relative immediacy of reinforcement, immediacy defined as the reciprocal of the delay of reinforcement.

Concurrent performances: a baseline for the study of reinforcement magnitude1
TL;DR: When a pigeon's pecking on a single key was reinforced by a variable-interval (VI) schedule of reinforcement, the rate of pecking was insensitive to changes in the duration of reinforcement from 3 to 6 sec.
