Case Study

Based on this scenario, explain how the psychologist's experience demonstrates the two major limitations of participant observation.

Case context: A psychologist joins a local support group as an active participant to observe their communication patterns. Over six months, the researcher forms close friendships with several group members. In their final report, the researcher notices they avoided describing negative interactions involving these friends. Additionally, other members mention that they began communicating more formally once the researcher joined the group.

Question: Based on this scenario, explain how the psychologist's experience demonstrates the two major limitations of participant observation.

Sample answer: The scenario demonstrates the two major limitations of participant observation. First, the researcher's presence altered the group's natural communication patterns, making them more formal. Second, by forming close friendships with group members, the researcher lost objectivity, resulting in experimenter bias where they selectively avoided reporting negative interactions involving their friends.

Key points:

  • The group changed their behavior (communicated more formally) due to the observer's presence
  • Forming close friendships compromised the researcher's objectivity
  • Experimenter bias was introduced when the researcher avoided reporting negative interactions

Rubric: Responses should explain that: 1) the researcher's presence changed the group's dynamics (members communicated more formally), and 2) the researcher's personal relationships led to a loss of objectivity and experimenter bias (avoiding reporting negative behaviors of friends).
