Toddlers’ Problem Solving: The Importance of Spatial Integration
While young infants appear competent in some task contexts, older toddlers often show difficulty with the same concepts. They apparently fail to understand something that infants are competent of. Such discrepancy in performance is puzzling, but only if task performance is taken to reflect knowledge or competency. The current study makes a different assumption: Namely that task performance refl...

برد عددی ماتریس مربعی a را با w(a) نشان داده و به این صورت تعریف می کنیم w(a)={x8ax:x ?s1} ، که در آن s1 گوی واحد است. در سال 2009، راسل کاردن مساله برد عددی معکوس را به این صورت مطرح کرده است : برای نقطه z?w(a)، بردار x?s1 را به گونه ای می یابیم که z=x*ax، در این پایان نامه ، الگوریتمی برای حل مساله برد عددی معکوس ارانه می دهیم.
15 صفحه اولSensorimotor Development in Cocaine-exposed Infants.
This study investigated effects of prenatal cocaine exposure on infant sensorimotor development. One hundred and sixty-seven 12-month-olds (74 cocaine-exposed and 93 unexposed) were assessed using the Bayley Scales of Infant Development (BSID). Ninety-seven had previously been evaluated on the Movement Assessment of Infants and the Test of Sensory Functions in Infants at age 4 months. On the BS...
متن کاملAutonomic alterations in cocaine-exposed infants.
BACKGROUND Heart rate variability (HRV) reflects autonomic control of the heart. After intrauterine cocaine exposure, asymptomatic newborn infants within 72 hours of life have decreased HRV. It is unknown whether these alterations are transient (acute effect) or persist in older infants and possibly reflect a teratogenic effect of cocaine. METHODS This study prospectively evaluated HRV in 2- ...
متن کاملProfiles of Reactivity in Cocaine-Exposed Children.
This study explored the possibility that specific, theoretically consistent profiles of reactivity could be identified in a sample of cocaine-exposed infants and whether these profiles were associated with a range of infant and/or maternal characteristics. Cluster analysis was used to identify distinct groups of infants based on physiological, behavioral and maternal reported measures of reacti...
