Questions using response
Problem 1
Why could different task instructions change a response-time comparison?
Answer and explanation
They can change what must be detected, interpreted, or done. Comparable instructions and timing methods are needed before comparing outcomes.
Response criteria
- Explain the relevant biological process accurately.
- Use the supplied evidence and show calculation steps with units where needed.
- Connect a labeled model or mechanism with the claim.
- State an assumption, evidence limitation, or useful next observation.
Problem 2
Which is a stimulus in a light-response model?
- A change in light
- The whole graph caption
- A claim of intelligence
- The mean alone
Answer and explanation
A change in light
The light change is the input that relevant receptors can detect.
