A few studies have indicated that dynamic measures of phonological awareness may contribute uniquely to the prediction of early reading development. However, standard control measures have been few and limited by floor effects, thus limiting their predictive value. The purpose of the present study was to examine the predictive value of a dynamic…

Latent class Poisson count models are used to analyse a sample of Danish test score results from a cohort of individuals born in 1954-1955, tested in 1968, and followed until 2011. The procedure takes account of unobservable effects as well as excessive zeros in the data. We show that the test scores measure manifest or measured ability as it has…

Hyperactive children appear to be at an increased risk for antisocial behavior in life. Follow-up studies using self-report and official criminal data have found that hyperactive children are more likely than controls to commit crimes, to be arrested for crimes, to be convicted of crimes, and to be diagnosed with Antisocial Personality Disorder in…

The present longitudinal study investigated the relationship between pre-school semantic skills (vocabulary, comprehension and sentence construction), phonological awareness and later word decoding and reading comprehension skills. More than 200 Danish children were followed from a speech therapist screening at the age of three, through a…
