6. There was at least one surprising finding in their results: people who did t’ai chi had the same BMI as the sedentary group, meaning they were just as overweight as people who did no activity. This surprised me, and I think surprised the authors too, because they said in the Introduction that t’ai chi was a form of moderate exercise. So my and the authors’ intuition were wrong! Can you identify one finding from this study that confirmed your intuition about meditation, exercise (whatever the form), and mental functioning? Was there a result that surprised you? 2 points  Age affecting all outcomes of the study was confirmed  A result that surprised me was that the meditation group was older than the other groups. I thought this was normally an activity for teens or young adults, so I was surprised. 7. Notice that when the authors described their results, like in the final paragraph, they say that t’ai chi and meditation+exercise may be associated with performance on executive function. This is a particular (and a little peculiar) phrase, one that they used very deliberately. We'll dig into this term in some detail later in the course, but for now, I want you to think about the difference between may be associated with and caused . Take a chance here to guess what you think the difference is between these two phrases. 1 point  Associated with means that they are related but you can have one without the other, while caused means they are directly related and can’t have one without the other. 8.
