Using an alternating treatment design, the acquisition, generalization, and maintenance of 8 tasks consisting of 2 communication functions (mand vs tact), 2 communication modes (receptive vs expressive), and 2 communicative symbols (gesture vs picture) were compared in 4 adolescents with profound intellectual disabilities and no receptive or expressive language. All Ss acquired 6 of the 8 tasks; the tasks not acquired were those in the receptive mode of manding, using either gestures or pictures. For all Ss, within the 6 tasks acquired, the tact function in the receptive mode using pictures was the most rapidly obtained and the most easily generalized and maintained, while the tact function in the expressive mode using gestures was the most slowly acquired and the most difficult to generalize and maintain. The communication function of manding was more easily acquired, generalized, and maintained than was tacting in the expressive mode for both types of symbols for all Ss. For the tact function, both types of symbols were acquired, generalized, and maintained better in the receptive mode than the expressive mode for all subjects. Also, for all Ss, pictures were more easily acquired, generalized and maintained than gestures. (PsycINFO Database Record (c) 2012 APA, all rights reserved)
