Preliminary resultsPreliminary results
From previous investigation, From previous investigation, tthe duration of the cycle in this case depends on the speed on which the user can act.
Even if the user had Even if the user had experience s/he could not experience s/he could not predict what next symbol predict what next symbol will be presented. Therefore will be presented. Therefore the first segment is the most the first segment is the most difficult, at least, during the difficult, at least, during the test. test.
