The Neuropsychological Test battery Vienna (NTBV)
The NTBV-short assesses several cognitive domains including reaction speed, selective attention, and information processing (6). In this regards, COG test was used. In this test, four images appear in a row and an image below it. The participant must decide, within a maximum of 1.8 seconds, which of the four images corresponds to the one below. The number of triggers provided was 60 stimulants. The test components consisted of sum hits (number of successful trials as Information processing index); sum correct rejection (number of successful trials in rejecting the improper response as selective attention index) and mean time hits (Reaction time index) (17) .
