This task measures the ability to focus concentration and efficiently process information. The participant monitors the screen for the appearance of one of two possible alternative stimuli which occur at unpredictable intervals. Each of the two stimuli requires a separate key to be pressed and the order of presentation is randomised.

This task measures the ability to encode, store and subsequently retrieve visual information. A series of 20 pictures from separate categories is initially presented one at a time.  Around 10 minutes later, the 20 original pictures are presented mixed with 20 matched pictures which are each very similar to the original picture. For each picture the participant must make a response as to whether the picture was the precise picture presented originally or a different one.

This task measures episodic memory for verbal information. A list of 15 words is presented one at a time on the screen for the participants to remember. Immediately afterwards using the keyboard the participants have 1 minute to type as many of the words as they can remember. Around 10 minutes later, the participants again are given 1 minute to type as many of the words as can be remembered. Finally, the 15 words are presented with 15 different words, one at a time in the centre of the screen in a random order. For each word, the participants must make a response as quickly as possible as to whether or not the word was in the original list.

This task measures the ability to hold spatial information in working memory and to retrieve it as quickly as possible. Three rows of 3 light bulbs are initially presented, with 4 of the bulbs being lit, and the subject has to remember the locations of these. The 3 rows of bulbs are then represented, each time with only one of them lit, and the participant must make a response each time as to whether or not the lit bulb was one that was originally lit.
