A Comparison of Procedures for Teaching Receptive Labeling of Sight Words to a Child with Autism Spectrum Disorder

A Comparison of Stimulus Set Sizes: Systematic Replication with Operant Analysis Acquisition Criteria

We conducted a systematic replication of Kodak et al.'s Journal of Applied Behavior Analysis, 53(1), 265-283 (2020) and Vladescu et al.'s Behavior Analysis in Practice, 14(1), 193-197 (2021) experiments on the effects of stimulus set sizes on skill acquisition. The researchers manipulated the stimulus set sizes by teaching 3, 6, and 12 sight words simultaneously during learn unit instruction. Researchers taught participants until the participant's responding reached the acquisition criterion for 12 different sight words per set size condition. The acquisition criterion was set for an individual operant, whereby when accuracy met criterion for a single sight word, that sight word was replaced in the following session. The results showed that the set-size-3 was more efficient in producing criterion-level responding during acquisition than the set-size-6, and -12, which was consistent with Vladescu et al.'s findings. However, the set-size-12 reliably produced the highest maintenance levels for all participants. The definition of "effectiveness" based on acquisition or maintenance was discussed.

Comparison of sounds and words as sample stimuli for discrimination training

A portion of children diagnosed with autism spectrum disorder (ASD) have difficulty acquiring conditional discrimination. However, previous researchers suggested that the discrimination of nonverbal auditory stimuli may be acquired more efficiently (Eikeseth & Hayward, 2009; Uwer, et al., 2002). For example, a child may learn to touch a picture of a piano after hearing the musical instrument more quickly than when the auditory stimulus is the spoken word "piano." The purpose of the present study was to extend previous research by assessing the acquisition of conditional discriminations with sample stimuli presented as either automated spoken words or high- and low-disparity nonverbal auditory stimuli (i.e., environmental sounds). Conditional discriminations with high-disparity environmental sounds as sample stimuli were acquired rather than or more efficiently than those trained with low-disparity environmental sounds and words as sample stimuli.

Evaluating Three Methods of Stimulus Rotation when Teaching Receptive Labels

The teaching of receptive labels (i.e., auditory-visual conditional discriminations) is common among early intervention programs for individuals diagnosed with autism spectrum disorder (ASD). Discrete trial teaching (DTT) is a common approach used to teach these receptive labels. Some have argued that the stimuli within the array, target and non-target, must be counterbalanced to prevent the development of undesired stimulus control. The purpose of the present study was to evaluate the effectiveness of three different approaches to stimulus rotation to teach receptive labels to five young children diagnosed with ASD. These approaches included counterbalanced, fixed, and clinician's choice. The results of an adapted alternating treatment design replicated across three stimulus sets and five participants indicated that all three methods of rotation were effective. Maintenance and generalization for targets taught in all three conditions was also assessed. The implications of the results with respect to current teaching practices in early intervention programs are discussed.

Common and Intraverbal Bidirectional Naming

Naming has been defined as a generalized operant that combines speaker and listener behaviors within the individual. The purpose of this paper is to reintroduce the concept of naming and its subtypes, common and intraverbal, distinguish it from other terms such as the tact relation, and discuss the role of naming in the development of verbal behavior. Moreover, a taxonomical change is proposed. The addition of the qualifier bidirectional would serve to emphasize the speaker-listener bidirectional relation and serve to distinguish the technical term from its commonsense use. It is hoped that this paper will inspire future basic and applied research on an important extension of Skinner's analysis of verbal behavior.
