The purpose of this series of experiments was to evaluate the effects of mixed mand-tact arrangements on the acquisition of mands and tacts in preschool-aged children. In Experiment 1, the effects of three training arrangements (mand-only training, tact-only training, and mand-tact training) were investigated with 3 typically developing children. Rates of acquisition in single (mand-only and tact-only) versus mixed (mand-tact) presentation were comparable, in contrast to earlier investigations. Experiment 2 attempted to clarify the equivocal findings of Experiment 1 by directly replicating the Carroll and Hesse (1987) investigation with 2 typically developing children. Results again demonstrated no clear benefit of mixed verbal operant training on tact acquisition. In Experiment 3, these same arrangements were evaluated with a boy with autism and included assessments to determine that a relevant establishing operation was in effect prior to each mand training session. Experiment 3 again failed to demonstrate the facilitative effects of mand-tact training on the acquisition of mands or tacts. Taken together, the data from these three experiments fail to support the improved efficiency of mand-tact training suggested by prior studies. Findings are discussed in the context of future research investigating mixed verbal operant arrangements. 相似文献

Therapists and educators frequently teach alternative-communication systems, such as picture exchanges or manual signs, to individuals with developmental disabilities who present with expressive language deficits. Michael (1985) recommended a taxonomy for alternative communication systems that differentiated between selection-based systems in which each response is topographically identical (e.g., card selection and exchange systems) and topography-based systems in which each response is topographically distinct (e.g., signed language). We compared the efficiency of training picture exchanges and signs with 3 participants who presented with severe language deficits; all participants acquired the picture-exchange responses more readily. 相似文献

A general outcome measure (GOM) can be used to show progress towards a long-term goal. GOMs should sample domains of behavior across ages, be sensitive to change over time, be inexpensive and easy to use, and facilitate decision making. Skinner''s (1957) analysis of verbal behavior may benefit from the development of GOM. To develop GOM, we conducted a review of the literature on mands, tacts, echoics, and intraverbals. The four areas reviewed included (a) an examination of the participant''s response form (i.e., vocal or nonvocal), (b) the type of prompt used, (c) types of materials used, and (d) timing of responses or sessions. Based on the review of the literature, we developed GOM for mands and tacts. This paper attempts to bridge the concept of GOMs with Skinner''s analysis of verbal behavior. 相似文献

Children with autism often do not learn to mand for information without structured teaching. Studies have demonstrated that manipulation of establishing operations (EOs), prompts, prompt fading, and differential reinforcement are effective in teaching children with autism to ask "wh" questions such as "what," "who," and "where." To date, no studies have evaluated procedures to teach children with autism to mand for information using "how." Teaching the mand, "how" is uniquely challenging because once the information regarding how to do something is provided, the EO may no longer be present. The following study evaluated a procedure to teach one child with autism to mand for information using "how" to obtain information to complete multiple activities. The results have implications for clinical application and future research on contriving EOs to teach the mand, "how." 相似文献

Many children with autism communicate through the use of alternative communication systems, such as sign language. Limited research has been conducted on the situations under which sign language will be acquired across verbal operants without direct teaching. The purpose of the current study was to evaluate exposure to sign language on the acquisition of signed mands, tacts, and intraverbals in a male child with autism. Results indicated fast acquisition of mands, tacts, and intraverbals without direct teaching. Results are discussed in the context of future research investigating exposure without direct teaching in individuals who communicate with alternative communication systems. 相似文献
