Although the effect of age was consistently negative for all three groups, it only reached significance for the SC monolectals, z SCmonolectals : age = −2.51, p < 0.05, and did not reach significance for the SC-SH bi-dialectals, z SC − SHbi − dialectals : age = −1.87, p =0.06 (marginally significant), or the SC-OD bi-dialectals, z SC − ODbi − dialectals : age = −0.77, p =0.06.
