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 The finding that confirmed my intuition was that “moderable aerobic exercise requiring constant mental exertion” correlate with better performance in attentional tasks. A result that surprised me was that there was little difference in the performance between the t’ai chi/meditation groups vs. the aerobic/sedentary groups, even though the prior was significantly older. 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
PSY 250 MPW 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 Even though the two variables are related, it doesn’t mean there is a cause and effect relationship between them. 8.
