The first introduction to psychology usually comes in the form of biology classes. Many biology students already come into class with at least basic understanding of psychology. They know that their genes determine how their bodies work, how they function and, to a certain extent, how they behave or what illnesses they may develop. But hardly any of these students have a clear understanding of what exactly DNA is, where it is found in the body, why it causes problems, and how it can be manipulated or altered.

In the case of development, the genes passed from one generation to the next only have to survive. Genes are merely instructions for doing things. People, as all living things, are programmed through thousands of years of natural selection to participate in behavior that is survival oriented. The basis for this programming is that the expression of specific genes that cause specific traits, such as aggressiveness, violence or sexuality. In the case of psychology, the genes that are passed on to us through our parents, grandparents, or other kin will determine such behavior.

Concerning understanding what is happening genetically, we’re still in the era of molecular biology. In this frame, genes are simply packets of information carrying instructions. This is how humans, plants and animals have been evolving for thousands of years. Nevertheless, in the last 50 years or so, a revolution in the field of psychology has occurred known as molecular biology or genomics. Genomics provides a new lens through which we could view the relationships between behavior and genes.

The molecular basis for behaviors and human memory is actually quite simple – it is all about the epigenome. The Epigenome is a mobile memory storage which determines whether or not a behavior will be expressed or not. Like all memory storage systems, it contains information that is “programmed” in advance by the genome.

What we now know is that the genetic material that determines behavior exists in all of us, but in varying amounts. Most of the variations come from the variation in the copies of genes inside the mobile memory storage of the person. The copy of the gene that determines the behavior is called the epigome. It’s this particular copy that we call the epigenome.

The importance of the epigenome in psychology and its relationship to individual differences has been revealed in a landmark study on twins. For years, autism research was based upon research on twins. However, it was discovered that there was substantial heritability (hitability) to behavior which existed between people who had identical twins but whose traits were very different. This study provided the first evidence of the significance of the epigenome in human behaviour and its link to abnormal behavioral disorders such as autism.

Even though the significance of this Epigenome in psychology has been established, many in the psychological area are hesitant to accept its potential as a substantial element in mental illness. 1 reason for this is it is difficult to define an actual genetic sequence or locus that leads to a behavioral disorder. Another issue is that there are just too many genetic differences between people to use a single DNA sequence to determine mental illness. Finally, even though the study on the Epigenome has been promising, more work needs to be done to find out the role that genetics play in complex diseases such as schizophrenia. If this finding holds true, it may be used as a foundation for analyzing other complex diseases that have complex genetic components.

If you’re interested in knowing more about Epigenetics and how it applies to psychology, I strongly advise that you follow the links below. My website discusses the exciting new technologies that are available now to better understand how Epigenetics affects behavior and the susceptibility to disease. You can even hear me speak on my epigenetics and autism blog. My research into Epigenetics is centered on understanding the ecological causes of disease, but I also have been involved in analyzing the relationship between Epigenetics and Autism. My future articles will also discuss diseases of the mind which can be affected by Epigenetics.
