Evaluation for KC3

Question 1

Research

Answer 1

Scientific research to support lateralisation. Damage to the left hand side has been shown to impact speech and language production and understanding. Furthermore, research evidence has shown the importance of the right hand side of the brain when it comes to recognising emotional facial expressions.

Question 2

Applications

Answer 2

Therapies and treatments. Neuroanatomy has helped us to understand the impact of aging and damage to the brain. This has helped us to understand how people could stop this damage or recover from it. We can do this because we understand brain plasticity and functional recovery.

Question 3

Weaknesses

Answer 3

Other research has suggested that functions are not as localized. For example, contemporary research into language using modern technology and brain scans suggests that many areas of the brain are used. This suggests that localisation and lateralisation theories do not fully understand the brain.
