Martin-Schultz scale. The Martin–Schultz scale is a standard color scale commonly used in physical anthropology to establish more or less precisely the eye color of an individual; it was created by the anthropologists Rudolf Martin and Bruno K Schultz in the first half of the 20th century.
The original Martin scale, summarized below, consists of 16 colors (from light blue to dark brown-black) that correspond to the different eye colors observed in nature due to the amount of melanin in the iris. The numbering is reversed in order to match the Martin–Schultz scale, which is still used in biological anthropology. In this case ...
The Neonatal Behavioral Assessment Scale (NBAS), also known as the Brazelton Neonatal Assessment Scale (BNAS), [1] was developed in 1973 by T. Berry Brazelton and his colleagues. [2] This test purports to provide an index of a newborn's abilities, and is usually given to an infant somewhere between the age of 3 days to 4 weeks old. [ 1 ]
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.
The Bayley-III has three main subtests; the Cognitive Scale, which includes items such as attention to familiar and unfamiliar objects, looking for a fallen object, and pretend play, the Language Scale, which taps understanding and expression of language, for example, recognition of objects and people, following directions, and naming objects ...
A seven-week-old human baby following a kinetic object. Infant vision concerns the development of visual ability in human infants from birth through the first years of life. The aspects of human vision which develop following birth include visual acuity, tracking, color perception, depth perception, and object recognition.
As of 2010, as many as 16 genes have been associated with eye color inheritance. Some of the eye-color genes include OCA2 and HERC2. [9] [10] The earlier belief that blue eye color is a recessive trait has been shown to be incorrect, and the genetics of eye color are so complex that almost any parent-child combination of eye colors can occur.
The Ballard Maturational Assessment, Ballard Score, or Ballard Scale, is a commonly used technique of gestational age assessment. It was devised by Dr Jeanne L. Ballard, professor emeritus of Pediatrics, Obstetrics and Gynecology at the University of Cincinnati College of Medicine.
