The sentences

marginally significantp = .049actually significant

For the 0° azimuth condition, a second-degree polynomial model revealed a marginally significant quadratic age effect (β = 5.26, p = .049, ΔR 2 = .042), suggesting possible accelerated decline in later middle age.

close to significancep = .056so close (0.05 < p ≤ 0.1)

Despite this, the age group remained close to significance (p = .056), suggesting a potential age-related trend in spatial processing abilities.

a marginal trendp = .091so close (0.05 < p ≤ 0.1)

The model showed only a marginal trend for predicting spatial advantage, F(1, 74) = 2.93, p = .091, R 2 = .038, with an unstandardized coefficient (β) of −.075 (p = .091).

marginal significanceno p-value reported

While these results hint at potential nonlinear age effects in co-located noise perception, the small effect sizes and marginal significance warrant cautious interpretation. 4.
