Document Summary
Chapter 2 notes an integrative approach to psychotherapy. Multidimensional integrative approach: psychological disorders are always the products of multiple interacting causal factors: biological, psychological, emotional, developmental. Genes: long molecules of dna at various locations on chromosomes within the cell nucleus: provide boundaries for our (physical) development. Abnormalities in sex chromosomes can cause ambiguous sexual characteristics. Most of our behavior, personality, and iq are polygenic. Human genome an individuals complete set of genes: creates many complex polygenic interactions. Quantitative genetics sums up all the tiny effects across many genes without necessarily telling us which genes are responsible for which effects. Molecular genetics focuses on examining the actual structure of genes with advanced technologies, allowing the identification of broad networks of genes that may be contributing to a particular trait. Only a small proportion of the genes in a cell are turned on or expressed: environmental (social and cultural) influences can determine this.
