Brain injury survivors with hippocampus damage may experience

Correct answer: B. Difficulty in recalling old memories

  • A. Vision and perception problems
  • B. Difficulty in recalling old memories
  • C. Inability to understand spoken or written language
  • D. Trouble with emotional reactions and decision-making

Explanation

The hippocampus is a critical region for memory formation and retrieval, especially in transitioning memories from short-term to long-term storage. Therefore, damage to the hippocampus can lead to difficulties in recalling old memories, making Option B the correct choice. Option A is incorrect because vision and perception are controlled by different parts of the brain, such as the occipital lobe. Option C is incorrect as language comprehension is linked to Wernicke's area. Option D is incorrect because emotional reactions and decision-making are more associated with the amygdala and prefrontal cortex.
