AQA GCSE · Question 13

Read the following information.

Adrianna and Jayla were at home watching a movie when they decided to make some popcorn.

Adrianna thought the popcorn looked burnt so she tried some to see how it tasted. It was hot and she burnt her lip. "Ouch, that hurt,” she said.

Jayla looked to see how far away the freezer was and knew she could reach for the ice cubes from where she was standing. She grabbed a handful and tried to ignore how cold they felt. "Your lip does look quite red,” she said, as she handed Adrianna the ice cubes.

From the information, identify two examples of situations where the parietal lobe was involved and identify two examples of situations where the occipital lobe was involved.

How to approach this question

1. Recall the primary functions of the parietal and occipital lobes. * Parietal lobe: Processes somatosensory information like touch, pain, temperature, and pressure. Also involved in spatial awareness. * Occipital lobe: Processes visual information. 2. Read through the scenario sentence by sentence. 3. Identify any actions or sensations related to touch, pain, or temperature and assign them to the parietal lobe. 4. Identify any actions or sensations related to sight or vision and assign them to the occipital lobe. 5. Select two distinct examples for each lobe.

Full Answer

Parietal lobe examples: 1. Adrianna feeling the heat and pain from the burnt popcorn ("It was hot... 'Ouch, that hurt'"). 2. Jayla feeling how cold the ice cubes were. Occipital lobe examples: 1. Adrianna thinking the popcorn 'looked burnt'. 2. Jayla looking to see how far away the freezer was.
This question tests your ability to apply knowledge of brain function to a real-world scenario. - **Parietal Lobe**: This lobe contains the somatosensory cortex, which processes sensory information from the skin. Therefore, feeling the heat of the popcorn, the pain of the burn, and the cold of the ice cubes are all functions of the parietal lobe. It is also involved in spatial awareness, so judging the distance to the freezer also involves the parietal lobe. - **Occipital Lobe**: This lobe contains the primary visual cortex. Any activity involving sight is processed here. This includes watching the movie, seeing that the popcorn looked burnt, looking at the freezer, and Jayla seeing that Adrianna's lip was red.

Common mistakes

Mixing up the functions of the two lobes. For example, incorrectly stating that 'seeing the popcorn' is a function of the parietal lobe.
