Objective. This paper highlights the main lines of etiological investigation of global developmental delay (GDD), mental retardation (MR) or intellectual disability (ID) and their specifi c order. GDD and MR/ID are chronic entities with onset during the developmental period, affecting personal, social, academic, occupational functions. Elucidating the etiology is important for establishing the ...

The need for national information infrastructures (NII) in the world’s least developed countries (LDCs) tends to be overshadowed by the nation’s severe deficiencies in physical infrastructure. Consequently NII may be inadequately addressed by governments and supporting agencies in their plans for stimulating social growth. The example of Singapore’s TradeNet and other lesser-developed countries...

Objectives: This research was performed to compare the results of two parental-based developmental questionnaires. Methods: In this study the developmental status of 196, 4-60 months old children were screened using Ages and Stages Questionnaires (ASQ) and prescreening developmental Questionnaire (PDQ) in 4 primary health care clinics in Tehran. Convenient sampling was used. Data was analyze...

Background: Development plans aimed at macro-management planning in a country significantly impact all functional fields. This study investigated the status and significance of the health sector in the first to sixth economic, social, and cultural development plans in Iran.  Methods: This was a review study using documentary analysis method. The review was conducted with an emphasis on purpose...

Most primate species produce offspring that are altricial and highly dependent upon caregivers. As a consequence, a host of developmental trajectories can be dramatically altered by variation in early experiences. We review the impact of early social experiences (in both experimental models and natural contexts) on developmental profiles in three species of nonhuman primates: marmosets, squirre...

The question of domain-specific versus domain-general processing is an ongoing source of inquiry surrounding cognitive control. Using a comparative evolutionary approach, Stout (2010) proposed two components of cognitive control: coordinating hierarchical action plans and social cognition. This article reports additional molecular and experimental evidence supporting a domain-general attentiona...

People with developmental disabilities often display, deficiencies in self-management and social skills in community based settings. Difficulties with self-management and social skills tend to pose particular difficulties for performing valued adult roles. Tools from behavior therapy have the potential to assist rehabilitation counselors in their work with consumers with developmental disabilit...

A fundamental question in developmental biology relates to the connection between morphological stages and their underlying molecular activity. Here we demonstrate that, at the molecular level, embryonic development in five Caenorhabditis species proceeds through two distinct milestones in which the transcriptome is resistant to differences in species-specific developmental timings. By comparin...

Clearly, the fossil record from the Cambrian period is an invaluable tool for deciphering animal evolution. Less clear, however, is how to integrate the paleontological information with molecular phylogeny and developmental biology data. Equally challenging is answering why the Cambrian period provided such a rich interval for the redeployment of genes that led to more complex body plans.
