The goal of this investigation was to examine how crossing roads with a friend versus alone affects gap decisions and movement timing in young adolescents and adults.
Ninety-six 12-year-olds and adults physically crossed a single lane of continuous traffic in an immersive pedestrian simulator. Participants completed 30 crossings either with a friend or alone. Participants were instructed to cross the road without being hit by a car, but friend pairs were not instructed to cross together.
Pairs of adolescent friends exhibited riskier road-crossing behavior than pairs of adult friends. For gaps crossed together, adult pairs were more discriminating in their gap choices than adult solo crossers, crossing fewer of the smaller gaps and more of the larger gaps. This pattern did not hold for 12-year-old pairs compared to 12-year-old solo crossers. To compensate for their less discriminating gap choices, pairs of 12-year-olds adjusted their movement timing by entering and crossing the road more quickly. For gaps crossed separately, both adult and 12-year-old first crossers chose smaller gaps than second crossers. Unlike adults, 12-year-old first crossers were significantly less discriminating in their gap choices than 12-year-old second crossers.
Compared to adults, young adolescents took riskier gaps in traffic when crossing virtual roads with a friend than when crossing alone. Given that young adolescents often cross roads together in everyday life, peer influences may pose a significant risk to road safety in early adolescence.
本研究旨在探讨与朋友一起过马路与独自过马路相比,对青少年和成年人的间隙决策和运动时机的影响。
96 名 12 岁的青少年和成年人在沉浸式行人模拟器中实际穿过一条连续交通的单车道。参与者完成了 30 次穿越,要么与朋友一起,要么独自完成。参与者被指示在不被汽车撞到的情况下过马路,但朋友之间没有被指示一起过马路。
青少年朋友之间的结伴过马路行为比成年朋友之间的结伴过马路行为更具风险。对于一起穿越的间隙,成年结伴者在间隙选择上比成年单独穿越者更具辨别力,穿越的小间隙更少,大间隙更多。对于 12 岁的同伴来说,这种模式与 12 岁的单独穿越者相比并不成立。为了弥补他们在间隙选择上的不具辨别力,12 岁的结伴者通过更快地进入和穿越马路来调整他们的运动时机。对于单独穿越的间隙,成年和 12 岁的第一穿越者选择的间隙都比第二穿越者小。与成年人不同的是,12 岁的第一穿越者在间隙选择上明显不如 12 岁的第二穿越者具有辨别力。
与成年人相比,青少年在与朋友一起穿越虚拟道路时比独自穿越时更冒险地选择交通间隙。鉴于青少年在日常生活中经常一起过马路,同伴的影响可能对青少年早期的道路安全构成重大风险。
