The proximodistal trend can be described as the __________ direction of motor development.
Describe the process of myelination and how it impacts information processing in childhood.
Responses may vary but should include all or some of the following information: Myelination occurs when children develop a myelin sheath, or a sheath of fatty tissue made of glial cells, around the axon of a neuron. Information processing, or the ability to process information, speeds up as a result of this process. In other words, children are able to think more quickly, which allows them to process information in complex ways as myelination occurs.
The __________ reflex occurs when infants turn their head toward the side of the face that was touched and open their mouth.
Describe how norms in development are determined.
Responses may vary but should include all or some of the following information: Developmental norms are determined by taking measurements, such as length or weight, to determine how development compares to other children in the same age group. The average number of children who have reached a particular task or measurement are then placed on a percentile scale to determine what the norms would be for that particular age group.
