Zotsatira za kukondoweza kwa transcranial direct current kwa dorsolateral prefrontal cortex yakumanja pa chilakolako ndi malingaliro oyipa mwa anthu omwe ali pachiwopsezo chogwiritsa ntchito zolaula zovuta: Kafukufuku wowona kawiri, wowongoleredwa ndi placebo

Kudalirika

Mbiri ndi zolinga

Chilakolako chogonana ndi kuchepetsa malingaliro oipa ndi zinthu zazikulu zomwe zimayambitsa vuto la kugwiritsa ntchito zolaula (PPU). Mwa anthu athanzi, njirazi zitha kuchepetsedwa bwino kudzera mu njira zoganizira zomwe zimayendetsedwa ndi prefrontal cortex. Komabe, PPU imagwirizanitsidwa ndi kusokonekera kwa ntchito zowongolera chidziwitso. Kafukufukuyu cholinga chake chinali kufufuza ngati transcranial direct current stimulation (tDCS) yolunjika ku dorsolateral prefrontal cortex (dlPFC) ingathandize kuwongolera chilakolako ndi malingaliro oipa mwa anthu omwe ali pachiwopsezo cha PPU.

Njira

Kapangidwe kosankhidwa mwachisawawa, mkati mwa munthu, koyendetsedwa ndi placebo kunagwiritsidwa ntchito, pomwe amuna 45 omwe ali pachiwopsezo cha PPU (zaka zapakati = zaka 20.18, SD = 1.03) adalandira zonse ziwiri (2.5 mA kwa mphindi 20) ndi tDCS yonyenga ku DLPFC yakumanja, ndi magawo olekanitsidwa ndi sabata imodzi. Pa nthawi ya tDCS, ophunzira omwe ali pachiwopsezo cha PPU adachita ntchito yolamulira chilakolako (ROC), poyerekeza chilakolako choyambitsidwa ndi cue ndi malamulo ophunzitsidwa, ndi ntchito yolamulira malingaliro (ER), kusiyanitsa zotsatira zoyipa ndi malamulo ophunzitsidwa. Mavoti odzipereka a chilakolako ndi malingaliro oipa adasonkhanitsidwa pa mayeso aliwonse.

Results

Zotsatira zathu zasonyeza kuti anthu omwe ali pachiwopsezo cha PPU adawongolera bwino chilakolako chawo ndi zotsatira zoyipa akatsogoleredwa kuti agwiritse ntchito njira zoganizira. Kuphatikiza apo, anodal tDCS ya dlPFC yoyenera panthawi ya kulamulira chilakolako idachepetsa kwambiri kuchuluka kwa chilakolako poyerekeza ndi kukondoweza kwachinyengo. Komabe, palibe zotsatira zoyendetsera right dlPFC anodal tDCS pa ER zomwe zidawonedwa.

Zokambirana ndi zolingalira

Zomwe zapezekazi zikuwonetsa kuthekera kwa tDCS ngati njira yatsopano yothandizira anthu omwe ali ndi PPU, zomwe zikupereka umboni woyamba woyesera kuti uthandizire kugwira ntchito kwake pochepetsa chilakolako.
