Essay On Formula-Fed Babies
The research proposed suggest that breast-fed babies are more intelligent than formula-fed babies. The independent variable is if a child was breast-fed or not. The dependent variable is the child’s IQ based on the Wechsler Adult Intelligence Scale (WAIS). Other important concepts to be understood is that this was a study and not an experiment, so the data could be skewed because it is based on the mothers self-reports of how much the child was breast-fed at the one-year examination. Sample of children were divided into 5 categories based on the duration of breast-feeding. Researchers adjusted the data for differences in maternal education and social class, to rule out preexisting differences that could have contributed to IQ differences.

They assessed the children’s intelligence using this scale which is consistent measurement for every child. The children with the duration of breast-feeding were associated with higher scores on the verbal, performance, and full scale WAIS IA. This evidence is observable, you can compare each child’s score. This evidence is valid because the WAIS is a consistent test that is able to compare scores evenly. Also, the researchers adjusted for differences that could affect the child’s scores such as maternal education and social class, allowing the researchers to rule out differences based on preexisting differences. This adjustment provided a more accurate result. The researchers explanation for the findings of higher scores associated with the breast-fed babies, is that human milk contains various hormones and other factors that enhance brain growth and maturation. The researchers also acknowledge the fact that differences between the groups could be from the children's genetic potential or the parent’s caregiving skills or motivation to nurture. I believe that this explanation of breast milk containing important hormones for enhancing brain growth and development, makes complete sense based on the evidence that children who were breast-fed score better the IQ
