Question

Strayer and colleagues have conducted many studies on the effects of cell phones on driver safety. In a typical study, participants are asked to drive through a neighbourhood in a driving simulator. Occasionally, and obstacle appears (a dog runs into the road, an area is closed off for construction, a traffic light suddenly turns red) and they measure the time required to brake (in seconds). In one study, 32 participants were randomly assigned to drive the route either in silence, or while talking to a confederate on a hands-free cell phone. Half the participants drove through a “novel” neighbourhood they had never seen before, and half drove through a simulation of their own neighbourhood. The JAMOVI analyses of this study are attached.

 

Which of the following is a correct description of the interaction (select all that apply)? in the second image

Estimated Marginal Means Condition * Neighborhood Braking 10 4 2 Novel Familiar X Phone Estimated Marginal Means - Condition * Neighborhood Neighborhood Condition Mean SE 5.87 0.562 6.00 0.562 8.62 0.562 3.50 0.562 Condition Phone Silence Phone Silence Silence 95% Confidence Interval Upper 7.03 7.15 9.78 4.65 Lower 4.72 4.85 747 2.35 Neighborhood Familiar - Novel O a. Familiarity affected braking times when people were talking on the phone but had no effect on braking time when people drove in silence. O b. The effect of talking on the phone depends on how familiar the neighbourhood is. O c. When talking on the phone people were faster to brake in a familiar neighbourhood than a novel neighbourhood, but when driving in silence, they were faster to brake in a novel neighbourhood than in a familiar neighbourhood. O d. Talking on the phone impaired braking in the novel neighbourhood but had no effect in a familiar neighbourhood.
