Collaboration in referential communication: comparison of youth with down syndrome or fragile X syndrome.

Referential communication was examined in youth with Down syndrome or fragile X syndrome in comparison to each other and to MA-matched typically developing children. A non-face-to-face task was used in which the participant repeatedly described novel shapes to listeners. Several dimensions of referential communication were especially challenging for the syndrome groups (i.e., they displayed below-MA performance), although there were differences in the dimensions that each syndrome group found to be most challenging. Independently assessed expressive language ability contributed to variations in referential performance, especially for participants with Down syndrome.

A generalized estimating equations approach to mixed-effects ordinal probit models.

Clustered ordinal responses, which are commonplace in behavioural and educational research, are often analysed using mixed-effects ordinal probit models. Likelihood-based inference for these models can be computationally burdensome, and may compromise the consistency of estimators if the model is misspecified. We propose an alternative inferential approach based on generalized estimating equations. We show that systems of estimating equations can be specified for mixed-effects ordinal probit models that avoid the potentially heavy computational demands of maximum likelihood estimation, and can also provide inferences that are robust with respect to some forms of model misspecification--particularly serial effects in longitudinal data.
