3. What is the simplest way to state the general hypothesis in this article? 2 points Does long term t’ ai chi’ and meditation benefit you more than aerobics? 4. The Methods section in this article is pretty challenging because it contains descriptions of complex measures like the visuo-spatial task switch test. Try not to get bogged down in the details of these measures. The important idea here is to understand in general what the four groups were and what variables they tried to measure in each group. This table might help make it clear: Group age VO 2 max BMI switch costs switch RT sedentary 46.92 28.86 -5.76 6.37-27.93 654.3 - 154.56 654.3 - 15 4.56 aerobic 44 .09 45.66 -9.67 2.62-23.78 489.63 - 96.89 400.84 - 53.90 meditation 46.63 4 1 .83 -9.53 3.53-23.3 477.41 - 188.88 401.23 - 122.83 t’ai chi 55.4 34.14-3.77 3.77 -29.3 453.94 - 110.84 14.15 - 11.97 The idea is that each cell in the table could be filled in with their data, so we'd know how, for example, meditators compared to aerobic exercisers in terms of BMI. If you had to summarize the methodology of this study, how would you say it? In other words, what did they do in the study in order to collect their data? 2 points
PSY 250 MPW It doesn’t matter which exercise you did there was little change in the BMI. The BMI in aerobics was a small change but not significant. 5. Do you know anyone who meditates or does t’ai chi ? Let's say I know someone who meditates but, in my opinion, she's not very quick mentally. In fact, I've seen her really struggle to follow a conversation and she gets confused easily. Do you think my friend’s mental abilities (or limitations) invalidate or refute the results of this study? 2 points I know someone who medicates, and I feel that medication can invalidate the study.
