Previous research in young adult samples has predominately used cross-sectional studies, limiting our understanding of within-individual differences in use behaviors and outcomes.

Results revealed FoMO significantly interacted with attentional bias in two critical phases: During early processing (0–500 ms), the PSMU/high-FoMO group exhibited attentional orienting deceleration to social media icons, whereas PSMU/low-FoMO showed attentional maintenance. In later processing (1000–1500 ms), PSMU/high-FoMO demonstrated attentional vigilance-maintenance, while PSMU/low-FoMO displayed avoidance. These findings indicate FoMO exerts a temporally dynamic interaction effect on attentional bias in PSMU—characterized by initial orienting delays followed by sustained attentional engagement with social media icons.
