Question
- A. Using a stopwatch to time responses
- B. Recording brain activity with an EEG
- C. Measuring heart rate variability
- D. Observing muscle contractions
Answer
The correct option is Using a stopwatch to time responses. This answer is correct because it matches the approved learning objective to interpret data from nervous-system experiments, including reaction-time data in the subtopic Structure and function.
Explanation
The correct option is Using a stopwatch to time responses. Using a stopwatch to time responses is correct because it directly supports the approved learning objective to interpret data from nervous-system experiments, including reaction-time data. This belongs to the subtopic Structure and function within The human nervous system, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from Structure and function.
Common mistake
Misinterpreting Reaction-Time Data
Students often misinterpret the significance of reaction-time data, confusing faster reaction times with better overall performance without considering the context of the experiment.
To fix this, students should focus on understanding the specific conditions of the experiment and how they relate to the reaction times, ensuring they analyze the data in context rather than in isolation.
