“…Namely, the hurdle does not change its place and direction itself because it is a stationary object. On the other hand, perceiving affordances become a more complex task when the objects to be perceived are moving than that of stationary ones because the speed and direction of moving objects change over time (Plumert & Kearney, 2018). In the context of dynamic affordances, opportunities for an action continuously change over environmental conditions.…”

Purpose of the study: The aim of this paper was to study gender differences regarding their perceptual judgment and movement behavior in the road crossing task. Methodology: A simulated road crossing environment outside the Human Motor Behavior laboratory (HMBL) was used to examine the individuals’ perceptual-motor behavior. Twenty-four young adults performed the road crossing task in the virtual environment judging whether the available gap was crossable or not crossable and then initiating movement depending on the perceptual information. Main Findings: Participants’ gap selection revealed that their cross-ability was influenced by vehicle speed, however, female participants made more errors relative to males. In addition, females took longer to cross and made unnecessary adjustments during crossings. The study findings suggest that females’ erroneous perceptual decisions and inconsistent locomotion behavior in road-crossing put them at higher risk relative to their male counterparts. Application of this study: The findings of this study may apply to developing training programs regarding pedestrian individuals. Training with performing road-crossing tasks may prove to be helpful for refining individuals’ perceptual judgment and movement behavior to minimize chances of accidents in road crossing. Specifically, having experience with the road-crossing task in a virtual environment may reduce the tendency towards risk-taking behavior. The novelty of this study: Most of the past research regarding pedestrian individuals’ road crossing behavior examined participants’ perceptual judgment (perception) in standing position only or did not analyze movement behavior in the actual walking set up. The approach utilized in our experiment was novel in this regard; individuals can choose to cross a gap and walk wearing a head-mounted display.

“…Crossing roads with continuous traffic is a complex perception-action task that involves perceiving and acting on dynamic affordances (Fajen, 2013; Plumert & Kearney, 2014, 2018). Dynamic affordances involve moving the self in relation to other moving objects, such as crossing a gap in traffic or stepping onto an escalator.…”

This investigation examined whether the mode of locomotion matters in how 8-, 10-, 12-, and 14-year-old children (N = 91) judge dynamic affordances in a complex perception-action task with significant safety risks. The primarily European American children in the sample came from the area of Iowa City, Iowa and were balanced for gender. The same children crossed a single lane of continuous traffic on foot and on bike (order counterbalanced) in identical immersive virtual environments. We found that although 8-year-olds chose significantly larger gaps when crossing on bike than on foot, these gaps were not large enough to compensate for their delay in entering the gap and their slowness in crossing the road. As a result, they ended up with less time to spare when exiting the roadway on bike than on foot. In contrast, 14-year-olds exhibited no difference in their gap choices on bike than on foot, nor did they exhibit a difference in their timing of entry into the gap. However, they crossed the road much more quickly on bike, resulting in significantly more time to spare when crossing on bike than on foot. The 10- and 12-year-olds' performance fit neatly between that of the 8- and 14-year-olds. We conclude that as children gained better control over the bike with age, they were better able to match their gap decisions with their crossing movements such that bicycling afforded even safer road-crossing than walking for 14-year-olds.
