q3 i? Perseverator group did not interact with Go/No-Go or Nebraska Barnyard performance in mixing or local-cost models at any time point. → Chevalier N. 2012

q3 · i? · associational · r2

In mixing-cost models, perseverator group × GNG and × NB interactions were non-significant at all ages (all ps > .058); local-cost models likewise showed no significant interactions (all ps > .084), so "the perseverator group interacted with neither GNG nor working memory performance at any age."

"Interestingly, the perseverator group interacted with neither GNG nor working memory performance at any age (all ps > .058)."

Discussion¶

Related Claims¶

• Inhibition and working-memory performance are associated with mixing costs (goal representation) at ages 4;6 and 5;3 but not at age 3;9 — related
• Local costs (switch implementation) showed no significant dependence on inhibition or working-memory performance at any of the preschool ages tested — related
• The proportion of perseverators declines steeply across the preschool period, from 38% at age 3;9 to 8% at age 5;3 — related
