Drews & Crouch compared the independent variable of the driving performance of 41 participants in a singular baseline conditions being the use of no mobile devices or other forms of distraction. This was done while carrying out a conversation on a mobile phone of a hand held device and a hands free device. Also while having other participants having an alcohol condition which followed the level of blood alcohol concentration of 0.8 g/l which is the legal limit in the UK.
In both of mobile device conditions, participants would carry out and engage in naturalistic conversations with a research subordinate on certain topics that were acknowledged earlier as being a topic that interested the participant being the dependent variable. There were results that were obtained from 7 different driving performance variables that would show both hand held and hands free devices conversations that were carried out would impair driving ability but there were no significant differences between these two types of mobile device use.
