"The Analysis of Verbal Behavior" ("TAVB") publishes experimental and theoretical papers relevant to a behavioral analysis of language. Normand, Fossa, and Poling (2000) reviewed the published studies in "TAVB" across several dimensions and found that despite the growth of the journal, most articles published in "TAVB" from 1982 to 1998 were…

This study examined the use of a progressive delay procedure with and without a concurrent activity to teach self-control to children with attention deficit hyperactivity disorder. Three participants were initially required to wait progressively longer periods of time for access to preferred edible reinforcers. After demonstrating this…

Cooperatives are systems organized along key principles to balance the distribution of wealth across organizational members. The cooperative movement has an extensive history and has contributed to the design and operation of a large variety of endeavors that seek to maximize returns to a maximum number of stakeholders. While cooperatives are…

The role of adult brain neurogenesis (generating new neurons) in learning and memory appears to be quite firmly established in spite of some criticism and lack of understanding of what the new neurons serve the brain for. Also, the few experiments showing that blocking adult neurogenesis causes learning deficits used irradiation and various drugs…

Modern psychological theories of spatial cognition postulate the existence of a geometric module for reorientation. This concept is derived from experimental data showing that in rectangular arenas with distinct landmarks in the corners, disoriented rats often make diagonal errors, suggesting their preference for the geometric (arena shape) over…

The "Lovaas Model of Applied Behavior Analysis" is a type of behavioral therapy that initially focuses on discrete trials: brief periods of one-on-one instruction, during which a teacher cues a behavior, prompts the appropriate response, and provides reinforcement to the child. Children in the program receive an average of 35 to 40 hours…

Fifty years after the publication of Skinner's "Verbal Behavior", some possibilities for the future of Skinner's "science of verbal behavior" are considered. Specifically, certain areas of development or advancement are examined which might be of special importance to the expansion and influence of the functional analysis of verbal behavior.…

Facilitating successful focus groups requires both science and art. One element that can fully challenge focus group facilitators includes how to handle the unfocused focus group. This article describes "unfocus" and the benefits and disadvantages of unfocus in focus groups. Lessons learned from and approaches taken on this journey are shared to…

Tolerance to effects of cocaine can be modulated by schedules of reinforcement. With multiple ratio schedules, research has shown an inverse relationship between ratio requirement and amount of tolerance that resulted from daily administration of the drug. In contrast, tolerance to the effects of cocaine on behavior under multiple interval…

Five experiments assessed associative symmetry in pigeons. In Experiments 1A, 1B and 2, pigeons learned two-alternative symbolic matching with identical sample- and comparison-response requirements and with matching stimuli appearing in all possible locations. Despite controlling for the nature of the functional stimuli and insuring all requisite…

Aphasia is an acquired language impairment that affects over 1 million individuals, the majority of whom are over age 65 (Groher, 1989). This disorder has typically been conceptualized within a cognitive neuroscience framework, but a behavioral interpretation of aphasia is also possible. Skinner's (1957) analysis of verbal behavior proposes a…

A recent survey by the new PIBA SIG suggests strong support for licensure among behavior analysts. This editorial will explore some of the common arguments against licensure and present some factual information to support or counter those arguments. The four common arguments are (1) licensure will hurt the science of behavior analysis (2)…

The time to resume task goals after an interruption varied depending on the duration and cognitive demand of interruptions, as predicted by the memory for goals model (Altmann & Trafton, 2002). Three experiments using an interleaved tasks interruption paradigm showed that longer and more demanding interruptions led to longer resumption times in a…

Applied behavior analysis is a hybrid tradition with roots in many mental health disciplines. Even with these diverse origins, the professional practice of behavior analysis remains distinct and identifiable. Given these factors the professional practice special interest group (SIG) for the Association for Behavior Analysis International has…

Leadership is a multifaceted construct. It requires mentoring as a lifelong experience. Leadership is not an isolated phenomenon, but an activity completely interrelated with those one leads. It can never be separated from its essential community or organizational context. This makes the experience of mentoring all the more critical. Adding yet to…
