The autoclitic is among the least studied and most complex verbal operant named and described by Skinner. The descriptive autoclitic is one subtype, which among other functions can describe the strength of the response. If the clarity of the stimulus is one source of response strength for tacts, manipulating stimulus clarity should evoke different…

REPORTED HERE ARE RESULTS OF A STUDY INITIATED TO EXAMINE PRINCIPLES INVOLVED IN THE EXPERIMENTAL MODIFICATION OF VERBAL BEHAVIOR. SIXTEEN UNDERGRADUATE FEMALE VOLUNTEERS WERE REQUIRED TO PRODUCE A VERBAL RESPONSE UNDER MANIPULATED LIGHTING CONDITIONS. BASE LINE SCORES WERE OBTAINED FOR EACH SUBJECT UNDER DIMLIGHT CONDITIONS. PUSHBUTTON SCORES…

Generalization of four retarded children's (five to eight years old) object naming responses to stimuli in the natural environment was assessed after training with either objects or pictures. Generalization was typically greater after training with objects. In a second experiment, an alternating procedure resulted in substantial increases in…

The theoretical functions of external feedback in SR and closed loop models of verbal learning are presented. Contradictory predictions from the models are tested with a three by three factorial experiment including three types of feedback and three amounts of rehearsal. There were 90 adult students run individually and they were required to learn…

A six-year-old nonvocal girl with autism who had acquired a variety of signs and imitative responses consistently failed to acquire a tact (labeling) repertoire. When procedures to transfer stimulus control from verbal to nonverbal stimuli were implemented, the subject quickly learned to tact all 18 target stimuli. (Author/DB)

FIVE STUDIES ARE REPORTED OF OPERANT CONDITIONING AND LANGUAGE DEVELOPMENT PRINCIPLES IN READING. THE FIRST STUDY OUTLINED THE RATIONALE AND PRINCIPLES UNDERLYING THE PROJECT. THE SECOND STUDY INITIATED AND REFINED APPLICATIONS OF REINFORCEMENT PROCEDURES FOR STUDYING EFFECTS OF DISCRIMINATION TRAINING ON READING. STUDY NUMBER THREE DEMONSTRATED…

This article reviews the basics of learning channels and how specification of stimuli can help enhance verbal behavior. This article will define learning channels and the role of the ability matrix in training verbal behavior.

Implications of the behaviorist and cognitive theories in language instruction are discussed in this article. Some contributions of Skinner, Politzer, Valette, Morton, Lane, and Mueller and Niedzielski clarify the behaviorists' view of language as a myriad of conditioned responses. In turn, the cognitive viewpoint, seen as the acquisiton and…

The symposium on which this report is based was motivated by the belief that scientific understanding of how man learns through language will some day help in the development and use of written instructional materials. The main purpose of the symposium was to take stock of the more promising findings and concepts about verbal learning processes in…
