Two hundred sixty-three twins and 94 singletons from families of twins were administered the 1960 version of the Templin-Darley Screening Test of Articulation for three to eight year olds. Mean scores for the twins fell significantly below the standard test norms. This study provides additional evidence that position of birth in large families, as well as SES level, can affect development in articulation for twins and singletons alike. The within-pair similarity of articulation was significantly greater for male identical twins than for male fraternal twins. No such difference was found between the female identical and fraternal twins.
