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.
q3 i? Among adults aged 40–81, older age correlates with higher overall entropy (r(297) = .166) and higher C3 entropy (r(297) = .170), indicating less consistent eye movements; only C3 entropy remains significant after controlling cognitive abilities. → Zheng 2026

q3 · i? · associational · r3
Correlational analysis of 301 middle-to-older adults performing a face recognition task with eye tracking. The article reports higher overall entropy and C3 entropy with age; only the C3 entropy association (r(286) = .142, p = .019) survived controlling aging-related cognitive abilities, so subsequent analysis focused on C3 entropy.
"it was associated with lower eye movement consistency, as reflected in higher overall entropy (r(297) = .1 66, p = .00 4, padjusted = .008) and C3 entropy (r(297) = .17 0, p = .00 3, p adjusted = .0 06, Figure 1C)"
Discussion¶
Related Claims¶
- In adults, face recognition performance is predicted by eye movement pattern, with eye movement consistency adding no additional variance — related
- Lower eye movement consistency (higher C3 entropy) is associated with poorer selective attention and inhibitory control — related
- A less eyes-focused pattern and lower eye movement consistency jointly predict poorer recognition beyond age and cognitive abilities — related
- C3 entropy partially mediates the relationship between age and face recognition performance — related
- Older age is associated with poorer face recognition: lower d′, higher false alarm rate, and longer response time — related
- Older age is marginally associated with a greater response bias toward affirming faces as seen, independent of eye movement behavior — related
