Individual differences with regards to biological psychology
Individual differences with regards to biological psychology
Understanding the Biological Influences
Genetics
- Genetic makeup influences individual differences. Genes carry information that determines your traits.
- Everyone has unique genetics, except for identical twins, leading to variations in physiological function and behaviour.
Brain Structure and Physiology
- Neuroplasticity refers to the brain’s ability to change and adapt as a result of experience.
- Differences in brain structure may contribute to variations in abilities, behaviour, and health.
Hormonal Differences
- Hormones can significantly impact mood, energy levels, and reactions to stress.
- Differences in hormone production or function can lead to behavioural differences.
Role of the Environment
- The environment can influence and interact with our biology. For example, stress can influence hormone production.
- Differences in environmental exposure (such as culture, family background, education etc.) can result in individual differences.
Interplay of Biological Factors
Interaction of Genes and Environment
- The interaction of genes and environment plays a critical role in individual differences, a concept known as gene-environment interaction.
- Epigenetics explores how the environment can change gene expression and subsequent behavioural outcomes.
Genes and Hormones
- Genes play a role in determining the production and function of hormones.
- Variations in genes can lead to differences in hormone production and sensitivity, which influence behaviour and health.
Hormones and Environment
- Hormones influence how we respond to our environment.
- Chronic stress can change hormone production and function, as the environment impacts the biological system.
