This study examined the effects of a picture racetrack game on the acquisition, maintenance, and generalization of picture labeling for 2 preschool students who are deaf. The game consisted of placing photographs representing individualized target vocabulary around a racetrack board and prompting the participant to sign each photo. A multiple baseline design across picture sets demonstrated that playing the picture racetrack game was functionally related to acquisition of vocabulary to 100% mastery on at least 3 consecutive sessions for each participant. Additionally, both participants maintained most of the vocabulary they acquired for at least 4 weeks after intervention, and they generalized picture labeling to a different presentation mode (i.e., a photo album).
