Originally published in 1988, the purpose of this title was to present a coherent summary of
the previous 30 years' of research on the way in which animals and humans distribute their …

Relative performance and reinforcement measures obtained from concurrent schedules
show just such an orderly relation. This chapter is concerned with an evaluation of …

Discusses the basic concepts and theoretical approaches of OH Mowrer's (1960) 2-process
theory of learning which argues that animal learning is an interaction between 2 …

Maximization theory, which is borrowed from economics, provides techniques for predicing
the behavior of animals-including humans. A theoretical behavioral space is constructed in …

Kelleher and Gollub (1962) and Kelleher (1966) have reviewed the important techniques
that have been used to study conditioned reinforcement. Chained schedules and other …

In a six‐key chamber variable‐interval initial links of concurrent‐chain schedules operated
on two lower white keys. Terminal links operated on four upper keys; green keys were …

Relative responding in initial links of concurrent‐chain schedules showed that pigeons
preferred free to forced choices and informative to uninformative stimuli. Variable‐interval …

Pigeons' pecks were reinforced according to a variable‐interval schedule. A delay‐of‐
reinforcement procedure was then added to the schedule, or a yoked‐control procedure was …

In a two‐key pigeon chamber, variable‐interval reinforcement was scheduled for a specified
number of pecks, emitted either on a single key or in a particular sequence on the two keys …

Publisher Summary This chapter deals with behavioral analysis and demonstrates free
choice preference. Once the preference is demonstrated, the next step is to explore some of …
