Teaching complex intraverbal responding to children with autism spectrum disorder (ASD) can be challenging and often requires careful programming. Divergent and convergent multiple control are particularly important elements to incorporate into intraverbal training programs, as well as procedures to ensure responding is under control of both…

We used a delayed non-concurrent pre- and post-intervention probe design to test the effects of a voice conditioning protocol (VCP) with 3 preschoolers with autism on (a) rate of acquisition of listener curricular objectives, (b) observing voices and the presence of adults across 3 settings, (c) selecting to listen to adults tell stories in free…

As we celebrate the 50th anniversary of the publication of B. F. Skinner's "Verbal Behavior", it may be important to reconsider the role of the listener in the verbal episode. Although by Skinner's own admission, "Verbal Behavior" was primarily about the behavior of the speaker, his definition of verbal behavior as "behavior reinforced through the…

Internal verbal processes were assumed to play a central role in complex school learning tasks. The research reported was concerned with a certain class of internal verbal behavior. The implicit associative response (IAR) was conceptualized as an internal verbal response that may occur when an individual sees or hears a word. Results of four…

Major purpose of the experiments was to use an instrumental response to study the form of semantic generalization gradients obtained following single-cue and discrimination training procedures. (Authors)

Conditional directives are used by speakers to instruct hearers which actions are to be taken should certain events occur. The authors demonstrate that conditional directives are distinct from indicative conditionals in which speakers predict what is likely to be observed should certain events occur. The 1st set of experiments shows that goal…

Acquisition, reversal, adaptation and inhibition of the orienting response were investigated in a mentally retarded sample and its CA and MA matched normal groups. (Authors)

Five profoundly mentally retarded adolescents and adults were taught to respond to an auditory-visual complex stimulus. Later, the auditory component alone was presented, and three subjects did not respond. These subjects then received a fading program which successfully established auditory stimulus control with two subjects. (MSE)

This study tested whether conditioning to one member of a compound stimulus can be blocked by presence of a second member to which the response was previously conditioned. Eight mentally retarded students (ages 7-9) were presented with words, sometimes accompanied by pictures. Six students performed best when words were presented without pictures.…

A study of the acquisition of mands (requests) and tacts (labels) relating to food and eating utensils in three individuals with severe mental retardation revealed that responses acquired as tacts did not readily occur as mands, but spontaneous manding was developed through a stimulus control transfer procedure. (MSE)

We examined some conditions under which a response acquired as a tact might facilitate the establishment of a mand. We taught 3 participants with developmental disabilities to tact the items ranked highest and lowest in a preference assessment and subsequently tested to see if the responses occurred as mands. All participants manded for the highly…

Research on learning and conditioning suggests that verbal response modification does not occur in the absence of the subject's ability to define verbally (1) the response-reinforcement relationships and (2) his intention to change his behavior in the direction of reinforcement. This seems to be true for operant conditioning of verbal behavior,…

One hundred twenty-eight preschool boys were subjects in a 4x2x2 factorial design to investigate the change in reinforcer efficacy as a function of prior stimulus exposure. The factors were: (1) amount of repetition, 5, 25, 45, or 65; (2) reinforcer, good or bell; and (3) satiator, good or bell. Two additional groups were run as control groups to…
