Evaluation of a self-instruction package for conducting stimulus preference assessments

Research suggests that inexperienced individuals cannot accurately implement stimulus preference assessments given written instructions alone. Training that includes written instructions supplemented with feedback from a professional with expertise in conducting preference assessments has proven effective; unfortunately, expert-facilitated direct training may not be widely available. In the current study, we used multiple baseline designs to evaluate the efficacy of an antecedent-only self-instructional package to train staff members to implement two methods of stimulus preference assessments. Accuracy was low when participants had access to written instructions alone. When access to enhanced written instructions was provided (i.e., technical jargon was minimized; instructions included pictures, diagrams, and step-by-step examples), inexperienced staff accurately implemented the assessments. Results are discussed in terms of opportunities to disseminate behavior-analytic technologies through self-instruction and print resources.     

Comparing self‐directed methods for training staff to create graphs using Graphpad Prism

An important skill for behavior analysts is creating graphs that clearly convey outcomes and conform to publication conventions. GraphPad Prism is software designed for creating scientific graphs, but no prior research has empirically evaluated training graphing skills using Prism. Two effective training methods are enhanced written instructions (EWI) and video modeling with voiceover instructions (VMVO), but no single‐subject studies have compared the effects of these methods. In this study, we compared the efficacy and social validity of EWI and VMVO for training staff to create graphs using Prism. A single‐subject design was employed to compare the effects of the methods on the individual performance of 11 graduate students. EWI and VMVO were both found to be effective, and more participants chose to use EWI.     

A blueprint for general‐case procedures illustrated by teaching adolescents with autism spectrum disorder to use a chip‐debit card

Individuals diagnosed with autism spectrum disorder (ASD) often respond poorly to novel stimulus combinations and may have difficulty discriminating across critical and noncritical stimulus dimensions without direct teaching. General‐case procedures and multiple‐exemplar training have been effectively used to address this deficit. In the current study, the experimenters outlined general‐case procedures with video modeling, prompting and reinforcement to teach three adolescents with ASD a generalized repertoire of using a chip‐debit card. A multiple‐probe across participants design demonstrated the effectiveness of these procedures. All participants acquired the skill, responding generalized from simulated teaching materials to four novel automatic payment machines, and maintained 4 weeks following teaching. Implications of using these general‐case procedures as a blueprint for future researchers to reference when teaching individuals with ASD a generalized repertoire of any skill are discussed.
