Smartphone Addiction Modulates Object-Based Attention.
Article in Behavioral sciences (Basel, Switzerland), 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Smartphone addiction has been linked to altered attentional functioning. However, it remains unclear whether these alterations are associated with enhanced attentional bias or impaired attentional shifting. Moreover, previous studies have largely relied on self-report measures, and evidence for attentional bias has mainly been obtained using smartphone-related stimuli. This study employed the classic two-rectangle paradigm to compare selective attention (including space-based and object-based attention) between individuals with high and low levels of smartphone addiction and to determine whether smartphone addiction primarily relates to attentional bias or attentional shifting. The results indicated that smartphone addiction significantly modulated object-based attention. More precisely, the high-addiction group exhibited a larger object-based attention effect than the low-addiction group, a difference primarily driven by the significantly longer reaction times of high-addiction individuals in the invalid different-object (IDO) condition, while no group difference was observed in the invalid same-object (ISO) condition. Furthermore, the high-addiction group exhibited significantly slower overall reaction times in the experimental tasks. These findings suggest that smartphone addiction is associated with attentional functioning and may involve poorer attentional shifting performance during object-based attention.
