Examining the impact of traffic environment and executive functioning on children's pedestrian behaviors.

The process of integrating visual information and planning a safe crossing is cognitively demanding for many young children. We assessed relations between traffic characteristics, aspects of children's executive functioning (EF), and pedestrian behavior, with the aim being to determine whether well-developed EF would predict safer pedestrian behaviors beyond the contributions of child demographic and traffic environment factors. Using the pretend road method, we studied a sample of 83 children aged 6–9 in a series of 5 crossing trials beside a real road in response to actual traffic conditions. Traffic characteristics and pedestrian behaviors were observed and measured across crossing trials. Both traffic characteristics and EF, most notably cognitive efficiency, were strongly related to children's pedestrian crossing behaviors. Traffic characteristics were also found to interact with children's ability to monitor their crossing performance. Examining developmental influences in pedestrian injury etiology broadens researchers' knowledge of and ability to prevent injuries by moving beyond describing what happens to children and examining why pedestrian injuries occur.

Influence of Virtual Reality Training on the Roadside Crossing Judgments of Child Pedestrians.

The roadside crossing judgments of children aged 7, 9, and 11 years were assessed relative to controls before and after training with a computer-simulated traffic environment. Trained children crossed more quickly, and their estimated crossing times became better aligned with actual crossing times. They crossed more promptly, missed fewer safe opportunities to cross, accepted smaller traffic gaps without increasing the number of risky crossings, and showed better conceptual understanding of the factors to be considered when making crossing judgments. All age groups improved to the same extent, and there was no deterioration when children were retested 8 months later. The results are discussed in relation to theoretical arguments concerning the extent to which children's pedestrian judgments are amenable to training.

Walking and talking: Dual-task effects on street crossing behavior in older adults.

The ability to perform multiple tasks simultaneously has become increasingly important as technologies such as cell phones and portable music players have become more common. In the current study, we examined dual-task costs in older and younger adults using a simulated street crossing task constructed in an immersive virtual environment with an integrated treadmill so that participants could walk as they would in the real world. Participants were asked to cross simulated streets of varying difficulty while either undistracted, listening to music, or conversing on a cell phone. Older adults were more vulnerable to dual-task impairments than younger adults when the crossing task was difficult; dual-task costs were largely absent in the younger adult group. Performance costs in older adults were primarily reflected in timeout rates. When conversing on a cell phone, older adults were less likely to complete their crossing compared with when listening to music or undistracted. Analysis of time spent next to the street prior to each crossing, where participants were presumably analyzing traffic patterns and making decisions regarding when to cross, revealed that older adults took longer than younger adults to initiate their crossing, and that this difference was exacerbated during cell phone conversation, suggesting impairments in cognitive planning processes. Our data suggest that multitasking costs may be particularly dangerous for older adults even during everyday activities such as crossing the street.
