question 11

Multiple Choice

An experiment was done to compare the effect of having a conversation via a hands-free mobile phone,having a conversation with an in-car passenger,and no distraction (baseline) on driving accuracy.Twenty participants from two different age groups (18-25 years and 26-40 years) took part.All participants in both age groups took part in all three conditions of the experiment (in counterbalanced order) ,and their driving accuracy was measured by a layperson who remained unaware of the experimental hypothesis. Which of the following sentences regarding the results of the simple contrasts of the distraction variable is correct?

• A)The second contrast tells us that driving was significantly different when having a conversation via a hands-free mobile phone compared to when having no conversation,F(1,18)= 105.81,p < .001.However,we cannot tell the direction of this effect without further analyses.
• B)The second contrast tells us that driving was significantly more accurate when having a conversation via a hands-free mobile phone compared to when having no conversation,F(1,18)= 105.81,p < .001.
• C)The second contrast tells us that driving was not significantly different when having a conversation with an in-car passenger compared to when having no conversation,F(1,18)= 2.09,p = .855.
• D)The second contrast tells us that driving was significantly less accurate when having a conversation via a hands-free mobile phone compared to when having no conversation,F(1,18)= 105.81,p < .001.
