Question

your dad has a bad habit of texting while he drives. you remind him that it is dangerous, but he asks why texting while driving poses such a hazard. which of the following is the most scientifically informed response to give your dad?

texting, and cell phone use in general, can induce an altered state of consciousness called change blindness, which can make driving dangerous.
texting requires taking one hand off the steering wheel, which is the main reason it is so dangerous.
there is a limit to how much attention is available in our conscious experience, which is what helps us respond quickly to new information (an important ability to have when driving).
texting is something most people do automatically and effortlessly, whereas driving requires great concentration. this contrast can lead to accidents.

Explanation:

1. Analyze Option 1: Change blindness is about failing to notice changes, not directly related to texting while driving's main hazard (attention allocation), so this is incorrect.
2. Analyze Option 2: While taking a hand off the wheel is a factor, the primary hazard is cognitive (attention) rather than just manual, so this is not the most scientifically informed.
3. Analyze Option 3: The concept of limited attention (cognitive load) is a key scientific principle here. Texting diverts attention, reducing the ability to respond to driving - related information quickly, making this a scientifically sound explanation.
4. Analyze Option 4: Texting is not typically done "automatically and effortlessly" in the sense that it still requires attention, and the contrast argument is not as scientifically grounded as the attention - limit concept.

Answer:

C. There is a limit to how much attention is available in our conscious experience, which is what helps us respond quickly to new information (an important ability to have when driving).
