Nature vs. Nurture, and the Other Issues in Developmental Psychology. What Causes Autism? Nature and nurture are always working together to produce all of our traits. EN: Can you describe a study that you feel illustrates the science of epigenetics? These researchers watched how rat mothers interacted with their babies. They discovered that some mothers naturally lick and groom their baby rats more than other mothers do.
They also noticed that the mothers that licked and groomed their rats the most wound up with offspring that grew up to be adults that were less stressed out when they were put into mildly stressful situations.
The mothers that licked and groomed their baby rats less wound up with offspring that were more stressed out. In order to determine if this was an effect of experience, the researchers cross fostered the baby rats, so the ones born to the high licking and grooming mothers were raised by the low licking and grooming mothers.
What they found was that it was the perinatal experience that made all the difference. So the question was, how can it be that these kinds of early experiences can have these long-term effects later on in adulthood? Meaney and Szyf traced the effect to epigenetics. Specifically, they discovered that in certain brain cells of baby rats, there are certain genes that get turned on when the babies are licked and groomed. Then, the turning on of those genes leads cells to build proteins that help moderate stress responses into adulthood, because the genes stay turned on.
EN: Can you describe how epigenetic research relates to humans? One is by looking at experiments that have been done on our primate relatives, the monkeys. The second way we can get insight into epigenetic phenomena in people is by doing correlational studies.
So far, these kinds of studies have revealed that this is indeed the case. Scientists have also discovered epigenetic effects of experiences that are less related to psychology. DM: Yes and no. Again, I need to start off with a caveat. Having said that, there is an increasing amount of data that suggests that growing up poor has long-term effects on people.
So, poverty seems to have consequences that produce effects that can be detected in the body decades later. EN: In your book, you describe the pitfalls of genetic determinism and you caution against people creating an epigenetic determinism.
A good work relationship requires trust, respect, self-awareness, inclusion, and open communication. As a result, maintaining our friendships can be hard and we often find that many people end up floating out of our lives as easily as they came in. Sometimes the reasons for being unable to love as much we want to stem from things that have nothing to do with the relationship or the other person. There are people in the world who are incapable of loving another person.
Sadly, it happens more often than anyone would like to admit. Begin typing your search term above and press enter to search. Press ESC to cancel.

Ben Davis October 21, They focused on participants of European genetic ancestry because researchers have identified genes linked to smoking and educational attainment in this population. Earlier research identified sets of genes linked to single behavioral outcomes, including smoking and educational attainment.
This study takes that line of research further by examining the relationship among those genes and whether a person smokes and how much education they received, focusing on differences across generations. Americans with higher levels of education are less likely to smoke. This pattern is more pronounced among more recent generations, the research team finds, suggesting the process is driven by changes in the social environment.
Social environment can shape the extent to which certain genes influence the association between behaviors.
