B. F. Skinner is the most eminent psychologist of the twentieth century, and it is no exaggeration to say that his discovery of operant learning (conditioning) has influenced the broader field of psychology, as well as other disciplines, including education, neuroscience, and philosophy. Skinner's discovery and elucidation of operant learning has…

In the present essay, commemorating the 60th anniversary of the publication of B. F. Skinner's "Verbal Behavior", I stand by and defend the judgment I expressed in my article "The Long Goodbye: Why B. F. Skinner's 'Verbal Behavior' Is Alive and Well on the 50th Anniversary of Its Publication" (2008c)--that Skinner's…

This article questions whether social justice can live within the structural racism present in the field of evaluation. Structural racism refers to the totality of ways in which societies foster racial discrimination through mutually reinforcing systems of housing, education, employment, earnings, benefits, credit, media, health care, and criminal…

When the B. F. Skinner Foundation reprinted Skinner's "Verbal Behavior" in 1992, Jack Michael wrote one of its two forewords, a detailed outline of the book's purpose and scope. On the 60th anniversary of the first publication (1957) of "Verbal Behavior", Jack reflects on the book's impact and its importance to the…

Jack Michael offered a course on verbal behavior almost every year throughout his teaching career. Jack was also interested in the application of Skinner's work and in 1976 began to offer a graduate course at Western Michigan University titled Verbal Behavior Applications. Jack and his students pursued the application of Skinner's work on verbal…

The task of extending Skinner's (1957) interpretation of verbal behavior includes accounting for the moment-to-moment changes in stimulus control as one speaks. A consideration of the behavior of the reader reminds us of the continuous evocative effect of verbal stimuli on readers, listeners, and speakers. Collateral discriminative responses to…

From the first mention of impairments in attention in the scientific literature by the Scottish physician Alexander Crichton in 1798, the correlation between educational attainment and learning has been persistently noted. Since then, the impact of attention deficits on school achievement has been a central component in a significant portion of…

To benefit from the exploration of their bodies and their physical and social environments, infants need to detect sensorimotor contingencies linking their actions to sensory feedback. This ability, which seems to be present in babies from birth and even in utero, has been widely used by researchers in their study of early development. However, a…

Learning Skinner's (1957) verbal behavior taxonomy requires extensive study and practice. Thus, novel classroom exercises might serve this goal. The present manuscript describes a classroom exercise in which two students analyzed Lady Gaga's song "Applause" in terms of its metaphorical arrangements. Through the exercise, students…

The purpose of the current paper is to describe the impact of applied behaviour analysis on language treatment for children with autism spectrum disorders (ASDs) diagnoses. Specifically, this paper will describe Skinner's theory of verbal behaviour and its contributions to evidence-based treatments for communication deficits among individuals with…

Some researchers claim that variability is an operant dimension of behavior. The present paper reviews the concept of operant behavior and emphasizes that differentiation is the behavioral process that demonstrates an operant relation. Differentiation is conceived as change in the overlap between two probability distributions: the distribution of…

A series of quotes from B. F. Skinner illustrates the importance of form in his analysis of verbal behavior. In that analysis, form plays an important part in contingency control. Form and function complement each other. Function, the array of variables that control a verbal utterance, dictates the meaning of a specified form; form, as stipulated…

We evaluated the effects of operant discrimination training (ODT) on the vocalizations of 3 boys with autism. We compared ODT to a stimulus-stimulus pairing (SSP) condition and a control condition in an adapted alternating-treatments design. ODT increased the target vocalizations of all participants compared to the control condition, and its…

The present investigation evaluated the effectiveness of category tact and match-to-sample instruction in facilitating the emergence of intraverbal responses (i.e., naming several items belonging to a specific category) for 2 children with autism. Results demonstrated the emergence of untaught responses, suggesting an effective instructional…

We investigated the involvement of PKA and PKC signaling in a negatively reinforced operant learning paradigm in "Aplysia", learning that food is inedible (LFI). In vivo injection of PKA or PKC inhibitors blocked long-term LFI memory formation. Moreover, a persistent phase of PKA activity, although not PKC activity, was necessary for long-term…
