 Gleason's 1976 paper with Weintraub, "The Acquisition of Routines in Child Language",
analyzed performance on the culturally standardized Halloween Trick-or-treat routine in 115 children aged two to sixteen years.Alterations in ability and the function of parental contribution were analyzed concerning cognitive and social components.They discovered that in the acquisition of routines
(in contrast to acquisition of much of the rest of language) parents' major interest is for their children to achieve accurate performance, with little stress on children's understanding of what they are expected to say.
