Subclaims¶

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q2 i? In Study 1, students' real-time focus tended to increase within a session, with each additional check-in raising reported focus by an average of .03 points on the 1–5 scale. → Michael D. Mrazek 2026 q2 i? In Study 2, the pre-registered replication, students' real-time focus again increased within a session with a similar slope. → Michael D. Mrazek 2026 (2)

q2 · i? · design · r3

Study 1, a naturalistic single-group pre-post study across five public high schools (N = 322 pre-test), used hierarchical linear modeling of Focus Coach check-in data. The article reports that “students’ real-time focus tended to increase within a session” with b = 0.03, p < .001, against the typical vigilance decrement.

"However, while using the tool, students’ real-time focus tended to increase within a session, with higher focus reported as the session progressed, b = 0.03, SE = 0.006, t (3985) = 4.42, p < .001 (Fig. 2)."

Study 2, a pre-registered direct replication with new participants (N = 695 pre-test; 615 with check-in data), replicated the within-session effect with b = 0.03, p < .001. No effect size was printed for this slope, so impact is uncoded.

"Students’ real-time focus increased within a session, b = 0.03, SE = 0.005, t(7716) = 6.52, p < .001 (Fig. 2)."
