Users may more clearly perceive the numbers associated with themselves

In a study conducted in 2023, researchers investigated how individuals process stimuli associated with themselves versus strangers, particularly focusing on number symbols. In the primary task, 123 participants had to recognize numbers that was initially assigned to themselves or to strangers. The analytical approach involved comparing mean reaction times for different associations. Confounders like age and vision were controled. Among other hypothesis, the primary hypothesis which posited that numbers that was initially assigned to the self would be more quickly recognized, was supported by the results with a large (p. 1524) effect size. This overview provides a concise synthesis of the most relevant results. For more details, please refer to the article page.

It is likely that numbers somehow associated with a user will be more salient for that user.
