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.
q3 i? When titration and domain overlap are entered together with their interaction, titration significantly reduces the age difference in storage+processing performance (estimate -0.49, p = 0.039) while overlap does not (p = 0.173) and the interaction is not significant (p = 0.651). → Jaroslawska 2019

Meta-regression (Table 2) of age differences in dual task performance including domain overlap, titration, and their interaction. The printed regression coefficients were Titrated -0.49 (p = 0.039), Overlap 0.19 (p = 0.173), Interaction -0.14 (p = 0.651); no standardized effect size is printed for this analysis.
"Domain overlap did not have a clear effect on effect sizes, whereas titration reduced the age difference in storage+processing task performance. Finally, there was no clear evidence of interaction between the two factors."
Discussion¶
Related Claims¶
- Titration of storage task difficulty reduces the age difference in dual task costs to a non-significant level — related
- Age differences in memory accuracy are smaller for verbal than nonverbal storage tasks, and domain overlap between storage and processing tasks moderates dual-task age differences — reports the opposite
- Titration of storage task difficulty substantially reduces age differences in both single-task and dual-task memory accuracy — related
- Older adults show a small but disproportionate age-related cost of concurrent processing on storage accuracy in working memory dual tasks — related
