Localisation of Function & Hemispheric Lateralisation (AQA A Level Psychology)

Lotta’s grandmother suffered a stroke to the left hemisphere, damaging Broca’s area and the motor cortex.

Using your knowledge of the functions of Broca’s area and the motor cortex, describe the problems that Lotta’s grandmother is likely to experience.

Lotta’s grandmother suffered a stroke to the left hemisphere, damaging Broca’s area and the motor cortex. Lotta worries that because of her grandmother’s age she will not be able to make any recovery.

Using your knowledge of plasticity and functional recovery of the brain after trauma, explain why Lotta might be wrong.

Kieran completes a quiz in his magazine and announces that he is ‘left brained’.

“That’s just silly”, Sam says. “You cannot just be ‘left brained’, the whole brain works together to carry out functions.”

“It’s not silly!” Kieran replies. “It says here that the left brain is responsible for speech and language.”

Discuss research into localisation of function in the brain and/or hemispheric lateralisation. Refer to Kieran and Sam’s discussion in your answer.
