This study investigated whether individuals with ASD (autistic spectrum disorders) are able to identify driving hazards, given their difficulties processing social information, Klin et al. (Archives of General Psychiatry 59: 809–816,
2002). Twenty-three adult males with ASD and 21 comparison participants viewed 10 video clips containing driving hazards. In half of the clips the source of the hazard was a visible person (social); in the other half the source was a car (non-social). Participants with ASD identified fewer social hazards than the comparison participants (
U = 163.00,
N = 44,
p < .05) but not non-social. Participants with ASD were also slower to respond than comparison participants,
F(1,40) = 4.93,
p < .05. This suggests that, although people with ASD can perceive driving hazards they may have specific difficulty identifying them if they involve a person.
