Hemispheric Lateralisation (AO3)

Question 1

What are the strengths of hemispheric laterisation?

Answer 1

• increases neutral processing capability (proven by Roger et al’s chicken study)
• split brain research supports it as it shows that the left side is dominant in language and the right is dominant in visuo-spatial tasks (left analyser, right synthesiser)

Question 2

What are the weaknesses for hemispheric laterisation?

Answer 2

• changes with age as after 25 lateralisation decreases, likely to recuit both sides of the brain to compensate for age related cognative decline
• laterisation in mathmatically gifted people to have better right hemisphere but suffer from more allergies

there is also a countet point to roger et al’s point because he uses animals to explain a human brain which is more complex
