Hi student!!
Thanks for the wonderful question (and the kind comment - I'm glad you found it useful ^^)! There are several things to unpack from your questions...I'll try my best to logically guide you through each part
1. Brain activity = thinking of self; so high brain activity = thinking of self a lot (low brain activity = thinking of self less)
2. Hershfield says that people see their future self as a different person --> this means that 1. lower brain activity when thinking about future self and 2. when people see their present self, brain activity is higher.
3. Answer A) - About 45% of people are willing to delay a reward when they consider themselves in the present. This is the lowest percentage among the three. When you interpret the data in the graph, it shows that people who view their present self are least likely to delay a reward. This support Hershfield's point that "out inability to make good choices" is impeded. BUT!!...The graph does not show that people who see their present self have the lowest brain activity. In fact, wouldn't the opposite be true (because of point 1)?
4. Answer C) - Roughly the same percentage of people who see another student and who see their future self would delay the reward. This supports Hershfield's point that "neural activity when they described themselves in a decade (future self) as similar to that when they diescribed celebrities (other people = another student)".
To answer your second question, Figure 1 essentially supports Emily Pronin's research from the passage.
1. The real situation is one where we know we are going to have to do something. In the passage it would be similar to the students who committed to drinking the nasty drink later that day.
2. The hypothetical situation is an imagined scenario, and in the passage, it is most similar to students drinking the nasty drink in the future (next semester).
3. Pronin's research shows that "we think of our future selves like we think of others (in the third person)".
4. This is shown in the graph; if you compare the present self REAL to the present self HYPOTHETICAL, you can see that the REAL case is much lower because people see the hypothetical (a future scenario) closer to the way they see their future self.
Hope this helps!!
Thanks again for the thoughtful questions, and KEEP MOVING FORWARD!
