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? Several reviewed studies agree the bilingual effect would emerge in more complex experimental tasks where there is a higher demand for control. → Giovannoli J 2020

q2 · i? · review · r3
Review narrative in the Introduction's moderator discussion: the review reports agreement among several studies that task complexity and control demand moderate whether the bilingual effect appears, citing Engel de Abreu et al. (2012) and Barac et al. (2016).
"Several studies agree that the bilingual effect would emerge in more complex experimental tasks where there is a higher demand for control (e.g., Engel de Abreu et al., 2012; Barac et al., 2016 )."
Discussion¶
Related Claims¶
- Bilingual children solve the Sky Search selective attention task faster than monolinguals across the studies using it
- Largest EF-training benefits emerge on the most demanding EF tasks and task conditions, so outcome measures must test the limits of children's EF abilities
- Bilingual children perform worse than monolinguals on attention tasks with verbal stimuli but not non-verbal ones
- Sustained aerobic exercise improves children's EFs, with dose-response benefits for the most EF-demanding task and math in the high-dose group only — related
