Psychology/How do I measure mental acuity?


Dear Dr. O'Neill,

I'm not an actual scientist, just an amateur, so please don't get angry at me. Hope you can help.

My aim is to investigate the effects and benefits of daily meditation on a person's mental acuity (I'm not aware of any reliable quantitative methods to measure this).

How should the person undergoing this study record their data, what should they record, and how can they measure their change of mental acuity over time, so my results are reliable and accurate?

How many participants should I have minimum to undergo this test? What else do I need to do?

Thank you


Mental acuity is a very vague term.  You probably want to break this down into specific kinds of cognitive tasks and functions such as short term memory, response time to find words and those kinds of things.  I think that there are some data in the psychology literature on the impact of TM on learning and specific cognitive skills.

I suggest that you look up some very short tasks that measure STM, etc.  Have the subjects record their meditation activities every day, but only test cognition before starting the mediation and at a specific time point later such as 2 or 3 weeks.  Otherwise, there will be learning effect of doing the cognitive task everyday.
