Development of an Implicit Association Test to measure attitudes towards speeding

The present research aimed to develop and evaluate an Implicit Association Test (IAT) to measure attitudes to speeding. In Study 1, 45 licensed drivers completed a questionnaire that assessed self-reported attitudes to speeding, and several variables theoretically related to attitudes, including speeding behaviour. Participants also drove a driving simulator, and completed the speed-related IAT. Observed IAT results suggested that attitudes toward speeding are negative, and were generally consistent with results derived from the self-report and speeding on the driving simulator. In Study 2, a further 45 licensed drivers underwent the Study 1 procedures, before being exposed to an intervention that was designed to increase negative attitudes to speeding (treatment group) or not (control group). Participants returned after 1-2 weeks for a second session, during which the Study 1 procedures were repeated. The intervention appeared to have a significant effect only on perceived crash risk for speeding. Thus, we could not adequately test the responsivity of the speed-related IAT to changed attitudes to speeding. In the control group, the IAT effect at Session 1 demonstrated a significant correlation with IAT effect at Session 2. Thus, the speed-related IAT appeared to be a valid and stable measure of attitudes to speeding, which might be used to measure attitudes in road safety research, without reliance on self-report. (a)
