MRI can be used to track brain activity, growth, and connectivity in children, [75] and can track brain development from when a child is a fetus. [76] EEG can be used to diagnose seizures and encephalopathy, but the conceptual age of the infant must be considered when analyzing the results. [77]
Growth charts have been constructed by observing the growth of large numbers of healthy children over time. The height, weight, and head circumference of a child can be compared to the expected parameters of children of the same age and sex to determine whether the child is growing appropriately. Growth charts can also be used to predict the ...
Accordingly, the scale would purportedly be able to show that infants and young children who demonstrate behaviors or responses more typical of an older chronological age would have higher intelligence. [1] Additionally, the Gesell Developmental Schedule has moved beyond merely identifying high-intelligence children and has become a research tool.
Due to natural variation, individuals pass through the Tanner stages at different rates, depending in particular on the timing of puberty.Among researchers who study puberty, the Tanner scale is commonly considered the "gold standard" for assessing pubertal status when it is conducted by a trained medical examiner.
