Document Summary
Multidimensional integrative approach: focuses on influences from different disciplines such as biological, psychological/behavioural, interpersonal/social, developmental and emotional. Emotions play a central role in the development of psychological disorders. Developmental critical period: period in the course of development when people are more or less reactive to given situations or influences compared to other times. Genes: very long molecules of dna at various locations on the chromosomes within the cell nucleus. Biological factors and genes do nothing but set the constraints or the limits for the individual"s abilities. Most of the traits are polygenenic; influenced by different genes to compromise one trait. Quantitative genetics: used to estimate the effects of genes in explaining differences and heredity but not necessarily revealing which genes are responsible. It is estimated that genetic influences on personality traits and cognitive abilities are about 50%. But psychological disorders, it is less than that [often, results are observed in identical twins]
