Short Answer

Suppose you are designing a naturalistic observation study on the play behavior of children at a local park, modeling your design after Jane Goodall's chimpanzee research. How would you operationalize 'without interference' in this park setting to ensure your study maintains high ecological validity?

Question: Suppose you are designing a naturalistic observation study on the play behavior of children at a local park, modeling your design after Jane Goodall's chimpanzee research. How would you operationalize 'without interference' in this park setting to ensure your study maintains high ecological validity?

Sample answer: To operationalize 'without interference' in a park setting, the observer should remain unobtrusive by blending into the background (e.g., sitting on a distant park bench) and avoiding any interaction or eye contact with the children. Additionally, the researcher must not introduce any toys, structures, or instructions, allowing the children to play exactly as they would if no observer were present.

Key points:

  • The observer must remain unobtrusive (e.g., sitting far away, blending in) to prevent reactivity.
  • There must be no direct interaction or communication with the subjects (children).
  • The researcher must not introduce external tools, toys, tasks, or instructions.
  • The environment must remain completely unmanipulated to preserve ecological validity.

Rubric: Score 2 points for detailing a specific method to remain unobtrusive (e.g., observing from a distance or blending in). Score 2 points for explaining that the researcher must not interact with the children or introduce any external stimuli/manipulations. Score 1 point for linking these actions to maintaining ecological validity or natural behavior.
