I think the authors’ choice to study the relationship between genetics and environment and its long term consequences using birth weight was an interesting one. Their explanation was rich with other research to back up their claims. I was very intrigued by the point they brought up about how being labeled “fragile, delicate, or sickly” could be part of the cause of the psychological or physical problems of low birth weight babies. I looked at the study they cited in the Journal of Pediatric Psychology from 1995 where they compared preterm- born 4½ year olds to a comparison group of 4½ year olds born a normal birth. To get around the variable of how the type of environment affects the children, both groups lived in environments free from socioeconomic disadvantages often associated with deleterious outcomes. One of the items on one of the tests given to the mothers of both groups of children stated that preterm babies would have more problems later on. An analysis of this item showed that the mothers of preterm children disagreed on this point more strongly than mothers of the comparison children. I found this interesting because the way the book quoted this study made me think that the parents of these preterm children would treat them as “fragile” children possibly causing problems later on. However, from the study it seems that maybe it is the other parents and the other children that view these preterm children as sickly which as a result, causes them to be just that. Both groups of mothers had high expectations about their children. Mothers of preterm children also believed somewhat more strongly in the power of the environment to produce positive outcomes. This point makes sense since these mothers would believe more in the “nurture” effect on their child’s future, despite their “nature” of being a preterm baby.
