Solution Steps

Step 1: Identify Lurking Variables
  • Lurking variables are factors that are not the primary focus of the study but could influence the results. In this study, the following variables could interfere:
    • Driving experience: More experienced drivers might have faster response times regardless of texting.
    • Type of phone: Different phones might have varying levels of distraction due to screen size or interface.
    • Texting ability: Some drivers might be better at multitasking, affecting their response time.
Step 2: Evaluate Blinding Options
  • Blinding is used to prevent bias in the study. In this context:
    • The person driving the vehicle could not know if they are texting or not: This is not feasible because the driver would naturally be aware of whether they are texting.
    • The researchers observing the trials and recording response time would not know if the driver was texting and driving or only driving: This is a valid blinding method, as it prevents the researchers from being influenced by knowledge of the driver's condition.
Step 3: Analyze the Feasibility of Blinding
  • The most practical blinding method in this study is to ensure that the researchers recording the response times are unaware of whether the driver is texting or not. This reduces potential bias in the data collection process.

Final Answer

  1. Lurking variables: Driving experience, Type of phone, Texting ability.
  2. The correct answer is D. The researchers observing the trials and recording response time would not know if the driver was texting and driving or only driving.
