A multiple design across student was used to evaluate the effects of taped number (TN)
intervention on the number-identification accuracy of 4 kindergarten students.During TN,
students attempted to name the number 0 through 9 on randomized lists before each was provided via a tape player 2 s later. All 4 student showed immediate increases and reached 100% in number-identification accuracy. One student reached 100% accuracy after TN was supplemented with performance feedback, reinforcement, and overcorrection.
