Subclaims¶

q3 i? Confirmatory mediation analysis shows significant indirect effects of age on d′ and false alarm rate through C3 entropy, alongside significant direct effects, indicating partial mediation. → Zheng 2026

q3 · i? · associational · r2

Confirmatory mediation analysis (PROCESS) in the same 301-participant study. For false alarm rate, the article reports both the indirect effect through C3 entropy (B = .001, p = .015) and the direct effect c′ were significant, consistent with a partial-mediating role for eye movement consistency decline.

"for d′, the indirect ef fect through C3 entropy was marginally significant (Figure 1D, B = -.005, 95% CI: [ -.0096, -.0010], z = -2.009, p = .0 45, padjusted = .090)"

Discussion¶

Related Claims¶

• Older age is associated with lower eye movement consistency in face recognition, reflected in higher overall entropy and C3 entropy — related
• Older age is marginally associated with a greater response bias toward affirming faces as seen, independent of eye movement behavior — related
• A less eyes-focused pattern and lower eye movement consistency jointly predict poorer recognition beyond age and cognitive abilities — related
• A more eyes-focused scanning pattern and higher eye movement consistency are each correlated with better face recognition performance — related
• Older age is associated with poorer face recognition: lower d′, higher false alarm rate, and longer response time — related
