In the article “Breast milk and subsequent intelligence quotient in children born preterm” A. Lucas and R. Morley (1992) conducted a thorough experiment on the effects of mothers’ breast milk on premature newborns. The researchers are not new to this line of work, they conducted another experiment before this one showing a correlation between preterm infants who drank breast milk and better development. In the article I read, the researchers did an exceptional job on perfecting their experiment. They had both dependent and independent variables, and an experimental group and a control group. Lucas and Morley also kept in mind the confounding variables, and incorporated those with their findings. By using random assignment, they choose …show more content…
Lucas and Morley wanted to find out if breast milk had an affect on preterm babies’ cognition later in life. The two of them looked at the children’s’ verbal performance, performance in general and their overall IQ of the two groups of children. They did this around the age of seven-and-a-half to eight years old, on three-hundred children. Not only did they want to obtain that knowledge, but they wanted to disprove other causations that could be possible. One of the other concepts they thought could affect this development was the parenting style itself. They outnumbered this idea in their experiments in a way I will talk about later in this essay. Looking at other causations they wondered if it was the interaction of breastfeeding that caused this development. After researching this concept, it was also proven false. As you now see, there was many reasons Lucas and Morley did this …show more content…
In the article “Breast milk and subsequent intelligence quotient in children born preterm” A. Lucas and R. Morley (1992) conducted a thorough experiment on the effects of mothers’ breast milk on premature newborns. As you have now seen, they found this to be true. Lucas and Morley found in an earlier study that when mothers chose to breast feed they were better developed. Both findings stand in favor that breast milk plays a crucial role in development. They also found biologically, “Human milk also contains numerous hormones and tropic factors (n15, n17) that might influence brain growth and nutrition.” (6). The researchers purspose of this study was to find a correlation between breast milk and IQ in children and dismiss other factors for causing the the change. They conducted this study, through a well designed experiment that had all the factors that a reliable experiment has. Lastly, they proved that their hypothesis was correct by stating, “We have shown that preterm babies whose mothers provided breast milk had a substantial advantage in subsequent IQ at 7 ½ to 8 years over those who did not receive mother’s milk, even after adjusted for a wide range of favors that might have confounded this comparison.”
