observations Flashcards
What is an observation?
observing and recording the behaviour of people
How is an observation different to other research methods?
it is non-experimental
What does non-experimental mean?
only watching the sample (no direct involvement)
When in a study would an observation take place?
before an experiment
What are strengths of using an observation?
- can see how people really behave and not how they say they would behave (self-report) = more valid
- good starting point for future research
What are the weaknesses of an observation?
- difficult to replicate
- observer bias
- lack of objectivity
- little/ no control over extraneous variables - cannot infer causality
What are the two types of observation that relate to the setting?
naturalistic & controlled
What is a naturalistic observation?
when participants are observed in their natural environment and nothing has been manipulated
What is a controlled observation?
when participants are observed in a laboratory (controlled setting) where certain variables can be manipulated
What are the strengths of a naturalistic observation?
- high in ecological validity
- valid (natural behaviours)
What are the weaknesses of a naturalistic observation?
- low control = harder to replicate = less reliable
- observer bias
What are strengths of a controlled observation?
- high control over extraneous variables
- standardised = more reliable
What are weaknesses of a controlled observation?
- lacks ecological validity (artificial environment)
- demand characteristics are more likely
- observer bias
What are the two sub categories of observations?
structured and unstructured
What is an unstructured observation?
writing down all behaviour seen during the observation period
What type of data is collected during an unstructured observation?
qualitative
