abstract
Ucwaningo oluningi lukhombisa ukuthi abantu abanezinkinga zokusetshenziswa kwezidakamizwa (i-SUD) bakhombisa ukucwasana ekucutshungulweni kwengqondo yezimo ezihlobene nezidakamizwa. Lokhu kubandlulula kusiza ekutholakaleni kwezimpawu zezinto futhi sekuphikiswana ngokuthi kudlalwa indima ebangela noma yokuqhubekisela phambili ukulutha. Izinkomba ezimbili ze-electrophysiological zokucubungula ukuqonda, izingxenye ze-P300 neSlow Potential (SP) zamandla ahlobene nomcimbi (i-ERP), zihlotshaniswa nokuthunyelwa kwezinsizakusebenza ezinakekelweni ezikhuthazayo ezifanele. Ekuhlaziyweni kwamanje kwe-meta-analysis P300 (300-800ms) kanye ne-SP (> 800ms) amplitudes asetshenziselwa ukuphenya ukuthi ngabe abantu be-SUD bakhombisa ukucutshungulwa okuthuthukile kokuqonda kwezici zezinto ezihlobene nezinkomba ezingathathi hlangothi njengokuphikisana nababambiqhaza bokulawula. Imiphumela ikhombise ukuthi osayizi be-P300 ne-SP amplitude effect babebakhulu kakhulu kubahlanganyeli be-SUD kunokulawula. Lo mphumela uchazwa ukunakwa okushukumisayo kwabasebenzisi bezinto. Ukuhlaziywa okwenziwe umengameli okwehlukanisiwe kuveze ukuthi womabili ama-P300 ne-SP amplitudes awazange alinganiswe yisayithi le-electrode (Fz vs. Pz), uhlobo lwezinto ezisetshenziswayo (izinto ezishukumisayo vs. nezidingo zomsebenzi (ama-paradigms asebenzayo uma kuqhathaniswa).
