Road Rage Essay

This experiment aimed to investigate road rage reactions in drivers. It used a 2×2 independent group’s factorial design. The independent variables were vehicle status and participant gender. The dependent variables were the duration of any verbal road rage reactions made by participants, participants questionnaire scores on the Propensity to Angry Driving Scale and participants heart rate’s before and after the experiment. The main hypothesis is that duration of verbal road rage reactions will be affected as a result of participant gender and/or the status of the confederate’s vehicle.

A 2-way ANOVA for independent groups was conducted to determine the effect of gender and vehicle status on the duration of p’s road rage responses. Levene’s test of equality of error variances was first carried out on the data, as this was not significant we can assume that the variances of the different conditions are similar and thus the subsequent ANOVA output may be used. The status main effect indicates that when the confederate drove a high status vehicle, males spent longer in their road rage reactions than when the confederate drove a low status vehicle.

The differences for females depending on the status of the vehicle are shown only to be small. Overall the high status vehicle induces a longer duration of road rage. The gender main effect shows that females spend less time making verbal road rage reactions compared to males, when the vehicle was of high status; there was no major difference for low status vehicles.
