How we measure the test and what type of memory recall people find the most challenging.
Warning ! These stats will give away some of the question types. We suggest taking the test first before reading this !
The memory test aims to challenge different types of memory recall. This includes images, shapes, names, words, numbers and phrases. We have grouped the test so that each type of memory challenge is tested twice. For example, most people taking the test will see two shapes of different colors and they will be asked to recall the colour of each shape.
Without question the two stage phrase. We ask a question similar to 'take the first right and the second left'. We then ask which left you should take. A huge 37% of people couldn't recall which turning to take. Interestingly, the vast majority of people who get it wrong answer incorrectly with the first turn (in this case, 'first right'). People can recall part of the phrase but not correctly.
Three others regularly come up. We show a picture of a dice and ask which number was visible. 22% of people get that wrong. We show a picture of a door with a house number and again 22% of people get the answer wrong. The strangest one perhaps given that people generally recall faces quite well is that we show a picture of a woman and ask a feature - such as what color were her eyes ? - 21% of people don't answer that correctly.
Clearly, this isn't a scientific test and people don't know what question they will be asked about an image. As mentioned above, we show a picture of a woman's face and ask about one of the features - the hair color, eye color, etc. It's not obvious what we will ask when we show the picture so recall is always going to be more difficult. In other cases, such as trying to memorise the number of a door, we make things a little more difficult by offering multiple choice options of number that are similar (such as 45, 54, 44, 55). It makes recall confusing as you can quickly become unsure in a way that an easier number selection (12, 44, 67, 99) might not.
There are a few questions that result in a false recall as low as 3%. For example, we show a picture of a single fruit and ask which fruit was seen. Only 3% of people get it wrong. It's clearly something that sticks in the mind very well. Additionally, we show a picture of a single object on a beach. Again, only 3% of people failed to recall what that was.
One of the most interesting stats is that we show people a single word during the test and also a single number. It's a four digit number (like '1234') and a four letter word (like 'door'). People are twice as likely to recall the word than the number. Finally - and one we don't understand as we are useless with names - we show a picture of a person with a name badge. Only 5% of people fail to recall the name on the badge which is one of the highest recall rates of any of the questions.
