Sfond u għanijiet
Il-vizzju tal-Internet (IA) kien reċentement iddefinit bħala diżordni li tikketta kemm il-kontroll tal-impuls kif ukoll is-sistemi ta 'premju. Speċifikament, defiċits inibitorji u preġudizzju ta 'kumpens kienu kkunsidrati relevanti ħafna fl-IA. Din ir-riċerka għandha l-għan li teżamina l-korrelati elettrofiżjoloġiċi u l-attività awtonomika [rispons tal-kondotta tal-ġilda (SCR) u rata tal-qalb] f'żewġ gruppi ta 'suġġetti żgħar (N = 25), bi profil IA għoli jew baxx [ittestjat bit-Test tad-Dipendenza fuq l-Internet (IAT) ], b'referenza speċifika għall-imġiba tal-logħob.
Metodi
Oscillatory brain activity (delta, theta, alpha, beta, and gamma) and autonomic and behavioral measures [response times (RTs) and error rates (ERs)] were acquired during the performance of a Go/NoGo task in response to high-rewarding (online gambling videos and video games) or neutral stimuli.
Riżultati
A better performance (reduced ERs and reduced RTs) was revealed for high IAT in the case of NoGo trials representing rewarding cues (inhibitory control condition), probably due to a “gain effect” induced by the rewarding condition. In addition, we also observed for NoGo trials related to gambling and video games stimuli that (a) increased low-frequency band (delta and theta) and SCR and (b) a specific lateralization effect (more left-side activity) delta and theta in high IAT.
Diskussjoni
Both inhibitory control deficits and reward bias effect were considered to explain IA.
