Do you ever find it difficult to remember a name or random object? As simple as these may be they present themselves as some of the hardest little things to remember. I often use a memory technique to make objects, names, and concepts come to mind more easily. Let’s say we have an airport lot number C27. Remembering this lot number the traditional way can be tricky. Here is how I did it…

Make the numbers/letters into a shape. Take the two and place it upright, then flip the 7 on its back so its facing upright, and finally lay the C right in the middle of the two and 7. This sounds complicated in words but here is an illustration:

If you use your imagination you can visualize this into an airplane. 27C is now in the shape of a plane to be used as the cue to remember your airport parking lot number.

I wanted to continue the discussion on caffeine by focusing on caffeine and memory. Based on popular belief, caffeine is always thought to boost mental awareness and therefore gets automatic credit in improving cognitive abilities such as memory and processing speed (thinking speed).

Memory

There has been numerous research articles written on the subject of caffeine and memory. By studying several journal articles, I wanted to take a look at the effects of caffeine on memory. According to Mednick, et al., their experimental outcomes suggested that while caffeine increases alertness, it impairs verbal memory and motor learning.(2008) Other research that has been done with children provide strong evidence that caffeine intake can impair cognitive performance tasks that include memory (Keller 1995). A study that examined caffeine levels and memory in rats found that caffeine decreases memory intake but improves memory retention (Angelucci, et al. 2002). So in other words, this study shows that caffeine can hurt intake in memory or new information but once its in, it can be retained more easily. To me, this makes sense if we apply it to humans. I know from personal experience that its harder to comprehend reading while under the influence of higher levels of caffeine. Sometimes my reading is jumpy or sporadic.

This segways into my next topic for my caffeine series, Caffeine and the speed at which we think.
