the present study explored the effects of a modified, intensive tact instruction intervention on the emission of spontaneous, or unprompted, mands and tacts during play in two typically developing, preschool siblings. intensive tact instruction involved presenting each participant 100 opportunities per session to tact stimuli prior to engaging in play. Picture cards were used as the tacting stimuli, which varied across five categories and five sets. Participants were reinforced for correct tacting responses or were conversely corrected for inaccurate or omitted responses. When compared to baseline, both participants exhibited increase in spontaneous tacts following such instruction. mands only increased slightly for one participant. this study adds to the research on the positive effect of using intensive tact instruction to help typically developing yet linguistically diverse children communicate.
