The Biological Approach
This page delves into the biological approach in psychology, which emphasizes the role of biological factors in behavior and mental processes. This information is crucial for students studying approaches in Psychology AQA A level.
The biological approach suggests that behavior and experiences are the result of biological processes, including genetics, hormones, and brain structure and function.
Definition: The biological approach in psychology focuses on how biological factors such as genes, brain structure, and neurochemistry influence behavior and mental processes.
Key aspects of the biological approach are explained:
- Evolution and behavior: How evolutionary processes have shaped human behavior
- Genetic basis of behavior: The role of genes in influencing personality traits and behaviors
- Biological structures: The impact of brain structure and nervous system on behavior
- Neurochemistry: The influence of neurotransmitters and hormones on mental states and behavior
Vocabulary:
- Genotype: The genetic makeup of an organism
- Phenotype: The observable characteristics resulting from the interaction of genotype and environment
The page discusses the concept of evolution in relation to behavior, explaining how certain behaviors may have evolved because they increased chances of survival and reproduction.
Example: The fight-or-flight response as an evolutionary adaptation that helped our ancestors survive threats.
The role of genetics in behavior is explored, including the concepts of genotype and phenotype. The page explains how genes can influence behavior directly or through interaction with environmental factors.
Highlight: Twin studies and adoption studies have been crucial in understanding the relative contributions of genes and environment to behavior.
The importance of biological structures, particularly the brain and nervous system, is emphasized. The page explains how different brain regions are associated with specific functions and how damage to these areas can affect behavior.
Lastly, the role of neurochemistry is discussed, focusing on how neurotransmitters and hormones influence mood, cognition, and behavior.
This comprehensive overview of the biological approach provides students with a solid understanding of how biological factors influence psychology, essential for AQA A Level Psychology notes and exam preparation.
