RESUMEN
Social networking sites, especially Facebook, have become increasingly popular over the past decades. However, besides the benefits of using Facebook, negative effects in the form of Facebook intrusion are also increasingly pointed out. Much of the research focuses on personality, emotional and social factors related to Facebook intrusion. However, there has been limited research on the relationship between this type of behavioural addiction and cognitive functioning. Consequently, the current study aimed to verify the relationship between Facebook intrusion and cognitive control in light of the dual mechanism of cognitive control model. Additionally, the study aim was to verify the impact of the Facebook-related context on cognitive control (proactive and reactive modes) compared to neutral and positive contexts. The participants (N = 82 young adults, 57 female, M = 22.24 years, SD = 2.67 years, age range 18-35 years) were divided into two groups based on their level of Facebook intrusion. The Facebook intrusion scale was used to assess the level of Facebook intrusion. The AX-CPT task was used to assess proactive and reactive control modes in three task contexts: Facebook-related, neutral and positive. The current study results show that the participants with high Facebook intrusion had greater reactive control than participants with low Facebook intrusion. The differences between Facebook-related, neutral context and positive context were not found. However, the present findings demonstrate the interaction between Facebook intrusion and task context in cognitive control. More specifically, participants with low Facebook intrusion had greater proactive control than participants with high Facebook intrusion in the Facebook-related and positive context.
