BIOLOGICAL AND ENVIRONMENTAL FOUNDATIONS I. GENETIC FOUNDATIONS A. The foundations of development are heredity and environment. Heredity supplies our genotype (genetic makeup)‚ while heredity and environment combine to form the phenotype (observable characteristics). B. The Genetic Code 1. Chromosomes store and transmit genetic information. Each cell in the human body contains 23 pairs of chromosomes. 2. DNA (deoxyribonucleic acid) molecules make up chromosomes. 3. A gene is a segment of a DNA molecule

Behavioral perspective The behavioral perspective (or behaviorism) can be traced back to the views of prominent psychology thinkers of the early 20th century like Skinner and Watson. This perspective posits the view that all human behavior is acquired through learning. Strengths Behavioral perspective is useful in the rehabilitation of sick people and people with autism. The behavioral perspective has changed the way people look at things that are observable. The behavioral perspective has helped

Psychological Perspectives: Essay 2 Psychology is a study which involves scientifically monitoring behaviour and mental processes in an attempt to understand and resolve them. In this second assignment I aim to discuss and evaluate the competing ideas of free will and determinism‚ whilst also assessing both biological and environmental reductionism as ways of explaining human behaviour. Firstly free will is fundamental to the understanding of most common sense theories of psychology. It is

Discuss biological approaches to addiction (9+16 Marks) The genetics of addiction: * People who have an addictive personality are likely to be predisposed to it because of their genes. * Family and twin studies have demonstrated that genes contribute towards the development of alcohol dependence‚ with heritability estimates of between 50 and 60 % for both males and females. McGue‚ 1999 * Fowler et al‚ 2007 – found that in a study of 1‚214 twins genetic influences played a role in the

Biological Effect Mechanisms of Damage Injury to living tissue results from the transfer of energy to atoms and molecules in the cellular structure. Ionizing radiation causes atoms and molecules to become ionized or excited. These excitations and ionizations can: * Produce free radicals. * Break chemical bonds. * Produce new chemical bonds and cross-linkage between macromolecules. * Damage molecules that regulate vital cell processes (e.g. DNA‚ RNA‚ proteins). The cell can repair

Biological Predispositions at Strife Genetic engineering‚ or genetic modification‚ is the direct manipulation of human and animal genome using biotechnology in hopes of procreating its masses. What happens: DNA or RNA is prepared and inserted into a host of the organism or a cell that is hybridized into the host. By manipulating its genome‚ scientists (who are so obsessed with “playing god”) are able to produce more desirable or efficient traits in humans and animals. The organism that is newly

The social groups in a society that tend to dominate over others are the ones who maintain the majority of the wealth‚ prestige

Biological and Humanistic Approaches to Personality PSY/250 University of Phoenix Theories in the field of psychology‚ more specifically personality‚ strongly rely on the collection of observational data. These observations are key in the development of certain theories. However‚ conflicting theories often arise. For that reason‚ in order to understand personality‚ different approaches must be studied. The biological approach explains that genes and hormones play a large role in personality
