objective(s): anti-epileptic drugs (aeds) have the potential to affect fetal development throughout pregnancy. considering the broad therapeutic indications of pregabalin (pgb), its potential teratogenic effects and the levels of homocysteine have been studied.   materials and methods: timed-pregnant mice received one of three doses of pgb (20, 40 or 80 mg/kg/day) or the vehicle control during ...

(1999). "Regressions" ("u"-shaped learning) in the acquisition of prosodic structure. This paper addresses learning of constraint rankings by children. We argue that constraint demotion cannot account for all developmental patterns observed in child phonology. Learning algorithms that allow for constraint promotion fare better, but some still cannot account for all developmental changes. Child ...

introduction: over the past two decades, the incidence of cesarean section in most countries has increased.developmental delay occurs when children do not reach their developmental milestones at the expected time. the main causes of developmental delay are often unknown. investigation of the prevalence of developmental delay and its effective factors in children from 4 to 12 months old in pakda...

* This research was supported by NIMH RO1 MH62480 and NSF BCS 00-91757, both awarded to JPS. Abstract – The Dynamic Field Theory (DFT) has been used to account for spatial recall biases in children and adults. This paper extends the DFT to a second spatial working memory task, position discrimination. The DFT captures details of adults’ discrimination performance, as well as predicting developm...

Humans have lived with chemical pollution for thousands of years, but the recent proliferation of industrial chemicals poses novel threats. In the new book Only One Chance, distinguished environmental health researcher Philippe Grandjean argues for special attention to developmental neurotoxicology, i.e. to the effects of chemical pollution on the developing human brain during pregnancy and in ...

This article presents a new model of transcoding numbers from verbal to arabic form. This model, called ADAPT, is developmental, asemantic, and procedural. The authors' main proposal is that the transcoding process shifts from an algorithmic strategy to the direct retrieval from memory of digital forms. Thus, the model is evolutive, adaptive, and particularly suited to account for learning and ...
