The Biological Approach- The Role of Genetics

Biological Approach Assumptions

Human behavior can be explained by biological factors like hormones, genetics, evolution, and the nervous system.

Genetics and Behavior

Genes determine unique physical traits and play a role in brain development and behavior.

Brain Structure Investigation

Brain scans like PET, CAT, MRI, fMRI, and SQUID magnetometry help study brain activity and anatomy.

Brain Structure in Psychology

Brain areas like hypothalamus, amygdala, and prefrontal cortex are linked to behaviors such as aggression, memory, and psychopathology.

Neurochemistry and Behavior

Neurotransmitters influence behavior, with imbalances linked to psychological disorders like schizophrenia.

Biological Approach Strengths

Provides scientific evidence, allows for the development of biological treatments for mental health issues and negative behaviors.

Biological Approach Weaknesses

Neglects environmental and social influences on behavior, may lead to individuals avoiding personal responsibility for negative behaviors.
