Study Notes on Types of Interviews, Observational Studies, and Case Studies in Research Methodology
Overview of Interview Types
Interviews are categorized into structured, semi-structured, and unstructured formats.
Structured Interviews:
Defined as interviews where every participant is given the same set of questions.
Example questions may include:
- Age of first sexual experience.
- Moments of significant personal interactions such as first kiss.
Emphasizes consistency in data collection (like in the Kinsey survey).
Information collected is not as anonymous as surveys, but responses are standardized for all participants.
Semi-Structured Interviews:
Begin with a set of standard questions but allow for flexibility based on responses.
Follow-up questions depend on the answers given by the participant.
Example:
- The National Crime Victimization Survey, which gathers information on whether individuals have experienced crime, starts with the same questions but varies based on responses (e.g., actual crime type, circumstances).
They require trained interviewers, making this method more costly and time-consuming than surveys.
Observational Research
Observational research can be categorized into two major types: naturalistic and laboratory observations.
Naturalistic Observations:
Observations take place in the natural environment where the behavior of interest occurs.
- Example Study by Deborah Peppler:
- Conducted with children in school playgrounds to study bullying behaviors and language.
- Methods included using hidden microphones and cameras for capturing natural interactions.
- It's common for subjects to forget that they are being observed after some time, leading to more authentic behavior.
Pros:
- Lower cost compared to laboratory setups.
- Observed behaviors are more spontaneous and natural.
Cons:
- May pose ethical concerns, making it difficult to conduct certain types of naturalistic observations.
Laboratory Observations:
Conducted in controlled settings, allowing for manipulation of variables.
Key Examples:
- The Strange Situation study by Mary Ainsworth, observed attachment behaviors between children and caregivers.
Pros:
- High control over experimental conditions.
Cons:
- More expensive to set up and conduct due to space and equipment needs.
- Subjects may alter behavior due to awareness of observation (experiments can become less natural).
Case Studies
Case studies can be categorized into two types: those focusing on rare conditions and those involving forbidden experiments.
Rare Condition Case Studies:
Focused on individuals with unique or rare psychological conditions.
Example of Sybil:
- A subject diagnosed with dissociative identity disorder (formerly multiple personality disorder), known for having numerous distinct identities (around 50 mentioned in sources).
- This case study became famous and led to various forms of media, though the validity of her diagnosis has been debated in the field.
Forbidden Experiment Case Studies:
Focus on ethically questionable experiments that inform scientific knowledge.
Example of Jeannie, the Wild Child:
- Confined and isolated by parents leading to limited interaction and language exposure which raised questions about the critical period for language acquisition.
- Although Jeannie became a subject of study, her emotional needs were not adequately addressed, leading to tragic outcomes after research funding ended.
Conclusion and Implications
- Each method employed in psychological research comes with its unique strengths and weaknesses.
- Ethical considerations play a critical role in determining research feasibility and importance.
- Case studies provide valuable insights into rare psychological phenomena but should balance ethical implications with scientific inquiry.
