They tested aerobic capacity through measuring each participants VO2 Max through a 1- mile walk. They tested the executive attention through the switch test, which measured switch RT and switch capacity. They measured each participants BMI and recorded their BMIs. Through their design of the experiment, the researchers carefully defined groups that could provide data to support and or deny their hypotheses.
PSY 250 MPW 5. Do you think my friend’s mental abilities (or limitations) invalidate or refute the results of this study? No, because the results of an experiment are supposed to explain a major trend in a relationship. It does not count for every case, so your friend would be an exception to this trend. 6. 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? 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 a small difference in the performance between the t’ai chi/meditation groups vs. the aerobic/sedentary groups, even though the initial people were significantly older. 7. Take a chance here to guess what you think the difference is between these two phrases. Even though the two variables are related, it doesn’t mean there is a cause and effect relationship between them. 8.
