Young adults subsequently spent less time looking at the background compared to both older adults (this effect while speaking was only marginally significant) [listening: t(177) = 4.33, p < .001, d = .65; speaking: t(177) = 1.95, p = .053, d = .29] and adolescents [listening: t(186) = 2.79, p = .006, d = .43; speaking: t(186) = 3.17, p = .002, d = .46].
