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 less than 0.05) but not non-social. Participants with ASD were also slower to respond than comparison participants, F(1,40) = 4.93, p less than 0.05. This suggests that, although people with ASD can perceive driving hazards they may have specific difficulty identifying them if they involve a person.
