Try this Memory Test on BBC Science. They have "several other tests"n:http://www.bbc.co.uk/science/humanbody/mind/index.shtml?brain that are worth checking out too.
I passed all the tests I took I can proudly say. Not always very fast, but at least I didn't cheat. My technique was to remember each word in a sequence of events that connects each word, but these connections span more than two words. I.e. To remember "dinosaur", "jumper", "guitar" I imagine: "a big green dinosaur", "the dinasaur puts on a red jumper", "the dinsaur is happy for his jumper because now he can play the guitar".
A long time ago I did a memory test experiment when I studied psychology. It was a sheet of 20 drawn objects. One group I just tested without any hints. A second group I told to think of each object related to themselfs (e.g. I play the guitar) and a third group I told to think of them in sequence (e.g. a jumper gets stuck in the guitar). The result was that the last two groups performed equally well and both 50% better than the first group. There are loads of confiding variables to consider and probably only considered half of them. It was after all just an experiment to learn about psychology, not to find ground-breaking results.
