Icon Sequence Memory Test

Working memory has a capacity limit. This is especially relevant for complex tasks and is therefore related to reasoning ability. A strong relationship between working-memory capacity and reasoning has been found in several studies1 and research indicates working memory as one of the best predictors of intelligence2.

Working memory is associated with 3 key functions: the simultaneous storage and processing of information, supervision (monitoring of mental operations, controlling their efficiency, and choosing the right resources for a task), and coordination (integration of information from different content domains)3.

This test assesses the element of the WM referring to the ability to control attention in order to either maintain relevant information or to disengage from irrelevant information4.


This Icon Sequence Test contains 10 questions in total. At the beginning of each question, you see a sequence of icons in quick succession. Then you will be shown a set of 8 icons and you must select the ones you just saw. 

Out of the 8 options, 3 to 5 will be correct. You get 1 point for each correct selection, and -1 for wrong selections.


This test is designed as an entertaining and educational tool. The results do not constitute a psychological or psychiatric evaluation of any kind and may not offer an accurate portrait of the mental fitness of the test taker. We do not guarantee the accuracy of the results and these should not be used as an indicator of the capacities of the individual for a specific purpose.
Responses may be recorded and used for research purposes or to be otherwise distributed. All responses are recorded anonymously.
