There is a well-documented propensity of males affected with developmental language/learning impairment. Results from this study demonstrate, unexpectedly, that this sex-ratio difference of males to females with developmental language/learning disorders was found to occur significantly only in families with a language/learning-impaired mother. In addition, a remarkably aberrant offspring sex-ra...

This paper describes the Pittsburgh Registry of Infant Multiplets (PRIM; Pittsburgh, Pennsylvania), the results of pilot research conducted in this registry, and the plans for future studies. The main focus of the registry is on psychological development and the risk for behavioral disorders. Particularly, characteristics associated with antisociality and the risk for substance use disorders (e...

This article discusses screening of language development in a pediatric office setting. It describes the relationship between language delay and various developmental disorders. It provides recent recommendations regarding the efficacy of formal language screening instruments, and suggests developmental guidelines for clinical observations. Referrals for specialty evaluations and services for e...

We evaluate the inferences that can be drawn from dissociations in syntax processing identified in developmental disorders and acquired language deficits. We use an SRN to simulate empirical data from Dick et al. (2001) on the relative difficulty of comprehending different syntactic constructions under normal conditions and conditions of damage. We conclude that task constraints and internal co...

This article is an updated review of the Pittsburgh Registry of Infant Multiplets including recruitment methods, data collection, and results of pilot studies conducted in this registry. The main goal of the registry is to study psychological development. The risk for behavior disorders including substance use disorders, as well as language development and dental health are among research targe...

In most people, language is processed predominantly by the left hemisphere of the brain, but we do not know how or why. A popular view is that developmental language disorders result from a poorly lateralized brain, but until recently, evidence has been weak and indirect. Modern neuroimaging methods have made it possible to study normal and abnormal development of lateralized function in the de...

the developmental, individual-difference, relationship-based model (dir) aims to describe and explain human psychological development in an integrated way. it has been believed that cognitive, linguistic, affective, personality abilities emerge within stages of “functional emotional development”. the human development influenced by a dynamic interaction among biopsyosocial variables. as a child...

METHODS The participants were 125 children with developmental speech and language disorders aged 6 to 9 years from 2 special...
