Describe the use of one brain imaging technique in investigating human behaviour, with reference to one example.

With reference to one example of human behaviour, describe neuroplasticity.

Explain how localization of function helps us understand human behaviour or cognition. Use one example in your answer.

Context: Health and well-being

Following a brain injury, Leila finds it difficult to fasten the buttons on her clothes. During rehabilitation, she practises this activity regularly with gradually smaller buttons. Over several months, she becomes more able to dress without assistance.

Apply your knowledge of neuroplasticity to Leila's improvement.

Explain why measurements of behaviour are needed when using one brain imaging technique to investigate human behaviour. Include one relevant example.

Context: Human development

Eight-year-old Tomas is having difficulty developing his spoken communication. He understands spoken instructions and can select pictures that answer questions, but producing the words he wants to say is unusually difficult. His teachers notice that his understanding continues to improve even though his spoken responses remain limited.

Apply localization of function to understanding Tomas's pattern of abilities.

Context: Learning and cognition

A museum is training new staff to identify replicas of objects by touch so that they can lead activities for visitors. Initially, the staff confuse objects with similar shapes and textures. The museum has several weeks available for training before staff begin leading the activities.

Using your knowledge of neuroplasticity, suggest how the museum could help staff improve their identification of the objects.

Context: Human relationships

Researchers want to investigate how people respond when receiving a friendly message from someone they know well. Participants will read messages from a close friend and messages containing the same words from an unfamiliar person. The researchers also plan to ask participants how connected they feel to each sender.

Analyse how one brain imaging technique could be used to investigate the participants' responses in this situation.

With reference to learning and cognition, evaluate the use of one or more brain imaging techniques to investigate one cognitive process, with reference to measurement.
