Question 2 Cross-sectional- is a research study, which involves taking a group of samples in a continuum or set in order to determine research variables is influenced by development. Its advantage is that a research can be completed within a very short period. On the other hand, longitudinal approach- is a …show more content…
The study offered the understanding and the intellectual ability and maturity of children at various ages. The study shows that different parts of brain grows at different times. It shows that there are spurt growths and periods. The study shows that in the development process. It starts with the cells that produces nervous system after fertilization, which then forms the neural tube. The cerebrum cells begins to divide at about six weeks after birth. They are formed rapidly. After that, there is formation of dendrites which continuous to grow. The challenge in that is that it is not possible to be determined by the genetic program. The brain continuous to produce neurons that are afterwards lost. The effect of its loss is that it starts the cortical
