What is Molecular Psychology?
Molecular psychology is a research field that studies how genes, brain chemistry and brain systems relate to differences between people in personality, emotion and behaviour. It combines behavioural genetics, molecular genetics and neuroscience.
What it does not claim
It does not claim that each emotion is a single molecule. Most traits are linked to many genes with tiny effects each, plus environment and life experience. Hormones and brain chemicals such as cortisol, dopamine and serotonin influence mood, but thoughts, sleep, stress and relationships influence them in return.
ONDA scope
ONDA does not measure hormones, neurotransmitters or mood. With an Apple Watch it reads HRV, resting heart rate and sleep data — indirect signs of stress load — and offers guided breathing practices.
