Rules
You will see several symbols, one at a time. The task is to compare each of these symbols with a symbol you have seen before. If the symbols are identical, click the 'yes' button. If the symbols are not identical, click the 'no' button. At the beginning of every block you will receive the processing rule. This tells you which of the recently seen symbols you have to compare with the current symbol. For example: 2-back means you have to compare the current symbol with the one before the last one. At 3-back it would be the symbol three symbols before, at 4-back the symbol four symbols before etc. Please note: Symbols are identical if they match in both shape and colour.
Example
This example illustrates a 2-back task. Imagine you have just seen in this order: the red symbol displayed opposite, a blue square, then that same red symbol again. You must click 'yes', since it repeats the symbol shown 2 steps before. Now imagine you have just seen in this order: a blue circle, a red square, then that red symbol. You must click 'no', since the current symbol differs from the one shown 2 steps before.
Timing
The test is split up into 6 blocks with different rules. Each block consists of 50 items.
