Five

Somatic intervention

• Alter structure and function of the brain and body to observe changes in behaviour

• Alter behaviour to observe changes in biological structure and function

• Observing the bi-directional relationship between biology and behaviour

Descartes theorised that

• human behaviour was the result of non-physical beings i.e. souls and spirit forces

• People and animals were hydraulic machines

• Vital spirit flowed from the brain to the muscles at sensory stimulation, causing swelling of muscles and limb movement

• Both humans and animals have consciousness

Helmholtz theorised that

• You can determine a person's personality or intelligence by feeling the pattern of bumps on the skull

• God implanted the immortal soul in the pineal gland

• Nerves are electrical wires that sent electrical currents to muscles, causing contraction

• A balance of bodily fluids is essential to maintain mental health

Tan was a patient of

• Gall

• Cajal

• Wernicke

• Broca

How did General Paresis influence biological psychology?

• Demonstrated the relationship between development of certain psychological conditions and human biology

• Suggested the biology played a greater role than environment on development of psychological disorders

• Revealed that all mental conditions have a biological background

• Demonstrated the relationship between effects of certain psychological conditions and human biology

How did Cajal contribute to biological psychology?

• Found that neurons were continuous

• Revealed that neurons cannot be classified by shape or size

• Revealed the structure and function of neurons

• Proposed that neurons had gaps (the synapse) between them, separating cells

The CNS is composed of

• brain and spinal cord

• nerves outside the brain and spinal cord

The PNS is comprised of

• Brain and spinal cord

• All the nerves outside the brain and spinal cord

The CNS and PNS work together by:
