Applied Psych. 07/01/10 Chapter 3: Nature and Nurture of Behaviour I. Introduction II.The Nature Component III. IV. V. I. Introduction - What makes us who we are? - Nature or Nurture? - Nature: genetics, DNA, genes, what we have genetically inherited - Nurture: everything else other than genetics (culture, religion, diet, disease, etc.) - Both are equally important and contribute to who we are - Interaction between the two, both influence one another II. The Nature Component a. Genes: Our Biological Blueprint - Chromosomes (46 chromosomes or 23 pairs): carry genetic information in the form of DNA molecules. - DNA is made up of different things including thousands of genes - Genes are the basic unit of heredity, which provide instructions that give an organism its structure. o One single gene can be responsible for a structure, but usually there’s multiple working together. o We call multiple genes working together gene complexes o Genes themselves are made up of nucleotides, which are biochemical building blocks/ biochemical bases. o 4 of them: guanine, cytosine, thymine, adenine o Considered to be the alphabet of life. o Sequence of nucleotides will determine what a gene does and what it does not do. o Chromosomes=books, Genes=words, Nucleotides=letters - Human genome has been mapped. o 30,000 genes o 99.99% genetically similar to one another - Repartition of the 0.01% difference: o 5% is differences among ‘races’ o 95% differences within a ‘race’ - Biologically race does not exist, but is a social construction. ‘meaningless concept’ - 95-98% of our DNA is shared with chimpanzees - 89-92% of our DNA is shared with mice b.

o Newest perspective in psychology o Theory of Evolution, by Darwin Primary goal is survival and transmission of genes into future generations for an organism Natural selection takes place, therefore only the fittest of the organisms within a species will survive. o Any behaviour trait characteristic that helped our ancestor survive/transmit genes into the future, are behaviours/emotions etc. displayed in human beings today. o Our fears that we have today have helped our ancestors in the past, this is why we have them. o Ability to adapt is one of our greatest strengths, help us survive and transmit genes. 2. Application Sexuality o Surveys tell us that men tend to like sex more o Clark and Hatfield Men are more into creational sex, and women are more into relational sex. o Men are not more sexual than women, just have different attitudes towards it. o Why? (according to evolutionary psych) Both men and women have the same goal, survival and transmission of genes. However in order to achieve this we have different strategies.
