Skinner's definition of verbal behavior, with its brief and refined versions, has recently become a point of controversy among behavior analysts. Some of the arguments presented in this controversy might be based on a misreading of Skinner's (1957a) writings. An examination of Skinner's correspondence with editors of scientific journals shows his…

Previous research on the acquisition of verbal behavior in children with developmental disabilities has focused on teaching four primary verbal operants: (1) "mand"; (2) "tact"; (3) "echoic"; and (4) "intraverbal". In Skinner's (1957) analysis of verbal behavior, he stated that each verbal operant is maintained by unique antecedent and consequence…

Amid the novel terms and original analyses in Skinner's "Verbal Behavior", the importance of his discussion of multiple control is easily missed, but multiple control of verbal responses is the rule rather than the exception. In this paper we summarize and illustrate Skinner's analysis of multiple control and introduce the terms "convergent…

The production of verbal operants not previously taught is an important aspect of language productivity. For Skinner, new mands, tacts, and autoclitics result from the recombination of verbal operants. The relation between these mands, tacts, and autoclitics is what linguists call "analogy," a grammatical pattern that serves as a foundation on…

The year 2007 marked the 50th anniversary of the publication of B. F. Skinner's "Verbal Behavior", a book that by Skinner's own account was his most important. The received view, however, is that a devastating review by a young linguist not only rendered Skinner's interpretation of language moot but was also a major factor in ending the hegemony…

Response variability, a fundamental characteristic of behavior, may be in some cases an induced effect of reinforcement schedules. Research on schedule-induced response variability has shown that continuous reinforcement results in less variability than intermittent reinforcement schedules. Studies on the effects of intermittency of reinforcement,…

The discrimination of the onset of joint control is an important interpretive tool in explaining matching behavior and other complex phenomena, but the difficulty of getting experimental control of all relevant variables stands in the way of a definitive experiment. The studies in the present issue of "The Analysis of Verbal Behavior" illustrate…
