“…In humans, evidence that adjacent and nonadjacent dependencies recruit different brain substrates has gained strength (Calmus et al, 2020;Friederici et al, 2006;Uddén et al, 2020). Nonadjacency has been shown to be acquired later than adjacency in development (Gómez & Maye, 2005;Teinonen et al, 2009), and direct comparisons between adjacent and nonadjacent dependencies showed increased learning for adjacent ones (Friederici et al, 2006;Öttl et al, 2017). One detour from this scenario was made by Uddén and colleagues (Uddén et al, 2009(Uddén et al, , 2012, who showed that multiple nonadjacent dependencies could be learned as efficiently as adjacent dependencies, provided that participants were given more time to learn (9 days instead of 5; see also Uddén et al, 2017).…”
