Question restatement: The prompt asks which scenario would most likely cause forgetting of a specific event, focusing on hippocampal damage.
Option 1: 'Damaging the hippocampus never causes forgetting of an event' This is incorrect because the hippocampus is essential for forming and consolidating new memories. Damaging it can indeed disrupt memory for events that are not yet consolidated.
Option 2: 'If the hippocampus is damaged at any time after the event' This overstates the effect. If a memory has already undergone substantial consolidation, later hippocampal damage may not erase the memory as readily. The timing matters, so this blanket statement is inaccurate.
Option 3: 'If the hippocampus is damaged a short time after the event' This is the most plausible choice. Shortly after encoding, memories are actively consolidating. Disrupting the hippocampus during this critical window impairs consolidation, increasing the likelihood of forgetting the event later.
Option 4: 'If the hippocampus is damaged a long time after the event' After a long delay, many memories may have become less hippocampus-dependent and more reliant on distributed cortical traces. Therefore, damage at that stage is less likely to produce forgetting of the specific event compared to damage during initial consolidation.
In summary, forgetting is most likely when the hippocampus is disrupted during the immediate consolidation period after encoding, i.e., shortly after the event.
