註釋

With our research we tried to find differences between healthy adolescents and adolescent with neonatal hypoxic-ischeamic encephalopathy in arithmetic processing with analyzing eye movement correlates for complex subtraction. More specifically, participants subtracted two digit numbers with regard to the borrow problem and to the distance between the first and the second operand. The differences between groups were perceived in reaction times, in eye movements and also in strategies of complex subtraction. The borrow problem affected the response accuracy in healthy group, while the adolescents with hypoxic-ischaemic encephalopathy did not perceive the difficulty of the tasks. As expected, participants with neonatal hypoxia were using more alternative strategies of subtraction, which were not based on the subtraction facts, recalled from the memory. And yet, we discovered that the distance between operands has no influence on subtraction.
