The last two decades have seen a marked rise in interest in what might be termed “time sense” and “number sense” and the potential relationship between them (for reviews see Buhusi and Meck, 2005; Bueti and Walsh, 2009; Nieder and Dehaene, 2009). “Time sense” refers to the ability that allows human adults (as well as infants and animals) to discriminate which of two sequentially presented stimu...

Background: Premature birth and subsequent admission to the neonatal intensive care unit (NICU) may impair the neurodevelopment of neonates. The present study aimed to determine the effect of developmental care on neurodevelopmental outcomes of newborns.Methods: This quasi-experimental study was conducted on 105 premature neonates (in three groups of 35 newborns). The control group receiv...

Background: The variability in the developmental skills is reduced after the first three years of life; therefore, it is necessary to identify and manage early developmental delays. Aim: The aim of this study was to investigate the effect of developmental stimulation program on the developmental measures of the toddlers. Method: The present randomized controlled clinical trial was conducted on ...

the grain aphid, sitobion avenae (hemiptera: aphididae) is one of the injuriously important pests of wheat and praon volucre (hymenoptera: braconidae) is one of its major parasitoids in iran. in this research, thermal requirements of the grain aphid and its parasitoid were evaluated at six constant temperatures (10, 15, 20, 25, 27.5 and 30 °c), 60 ± 5 % relative humidity and a photoperiodicity ...

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...

Sea Urchin is one of the most useful tools in developmental biology studies because this organism has the simplest kind of developmental stages. We aimed to determine developmental stages and timetable of Echinometra mathaei embryo (the species of Persian Gulf). The spawning of E. mathaei was induced by 0.5M KCl injection (1ml) into the coelomic cavity. After fertilization, embryos wer...

Nature and origins of mathematics diculties in very preterm children: a dierent etiology than developmental dyscalculia. Abstract Background. Children born very preterm (<32 weeks) are at high risk for mathematics

BACKGROUND Arithmetical skills are essential to the effective exercise of citizenship in a numerate society. How these skills are acquired, or fail to be acquired, is of great importance not only to individual children but to the organisation of formal education and its role in society. METHOD The evidence on the normal and abnormal developmental progression of arithmetical abilities is revie...

In developmental robotics (Weng et al., 2001; Lungarella et al., 2003), one aims to investigate the mechanisms that may allow a robot to continuously discover and learn new skills in unknown environments and in a life-long time scale. Of particular importance is the fact that the set of these skills and their function(s) are at least partially unknown to the engineer who conceive the robot init...
