The impaired inhibitory control of social media addicts’ in response to social media cues
摘要
Individuals with social media addiction (SMA) cannot generally control their own behavior, and therefore have insufficient inhibitory control. Based on this, the present study jointly investigates the effects of SMA on the inhibitory control (including cognitive inhibition and response inhibition) of addicts. It examined these effects under different types of cues, such as social media cues, non-social media cues, and no cues, using behavioral and EEG tasks. A total of 43 participants (N = 43; M = 20.63 yrs.±2.183) completed the NoGo-Flanker task. Forty-three participants were assigned to the SMA group (N = 20) and the non-addiction (NA) group (N = 23) by Bergen Social Media Addiction Scale. The results showed that, when completing the behavioral task, the SMA group exhibited faster RT and lower ACC compared to the normal use group for all three types of cues. During the EEG task, the SMA group also showed smaller N2 amplitudes and larger NoGo P3 amplitudes under the non-social media cue and the no cue, compared to the NA group. When exposed to social media cues, addicts become more impaired behaviorally, with no increased activity observed at the neural level. Future research should focus on the criteria for developing SMA.
