Physcology Biological
Biology is defined as “the study of life” from the Greek, bios meaning ‘life’ and logos meaning ‘study’. This approach has one key assumption. Our behaviours and the way we experience things are due to our biology. Genes, chemicals such as hormones, brain structure and systems. They believe that the environment does not have any influence on your condition. This approach tends to fit in with the nature nurture debate.
A biological perspective is relevant to the study of psychology in three ways:
1. Comparative method: different species of animal can be studied and +compared. This can help in the search to understand human behaviour.
2. Physiology: how the nervous system and hormones work, how the brain functions, how changes in structure and/or function can affect behaviour. For example, we could ask how prescribed drugs to treat depression affect behaviour through their interaction with the nervous system.
3. Inheritance: what an animal inherits from its parents, mechanisms of inheritance (genetics). For example, we might want to know whether high intelligence is inherited from one generation to the next.
Each of these biological aspects, the comparative, the physiological and the genetic, can help explain human behaviour
Arnold Gesell (1880-1961) followed the works of Darwin and other evolutionists, eventually developing the Gesell Maturational Theory. His theory contends that development in childhood and adolescence is primarily biological, or genetic, in origin. Biology and genetic inheritances determine predictable patterns of biological behaviour that Gesell termed norms. He felt that developmental changes in a child's behaviour are a result of the aging process rather than from learning, injury, illness, or any other life experience.
Our genes affect our behaviour, Whether or not a gene is expressed depends on two different things: the interaction of the gene with other genes and the continual interaction between the genotype and the environment.
