L3 Field Experiments

• What is an extraneous variable?


  a variable that can affect the DV, that we want to get rid of.
• What is a field experiment?


  A field experiment takes place in a natural setting.
• What does a researcher do in a field experiment?


  The researcher changes the independent variable to see its effect on the dependent variable.
• How do field experiments differ from lab-based experiments?


  Field experiments occur in natural settings, while lab experiments are conducted in controlled environments.
• What is a major weakness of field experiments?


  A lack of control over extraneous variables.
• Why is it hard to assume cause and effect in field experiments?


  Because extraneous variables may influence the results.
• Why are field experiments less replicable than lab experiments?


  Different participants with varying moods and experiences affect behavior.
• What are demand characteristics in the context of field experiments?


  Demand characteristics occur when participants are aware they are in an experiment and change their behavior.
• How do field experiments reduce demand characteristics?


  Participants are often unaware they are part of an experiment.
• What is ecological validity in the context of field experiments?


  Ecological validity refers to the extent to which findings can be generalized to real-life settings.
• What is a strength of field experiments regarding ecological validity?


  Field experiments are less artificial and can reflect real-world behavior.
• Why is it beneficial that participants do not show demand characteristics in field experiments?


  It allows participants to behave more naturally, increasing the trustworthiness of results.
• What are the weaknesses of field experiments?


  They can have extraneous variables affecting results and are hard to replicate.
• What is one strength of field experiments regarding demand characteristics?


  They have fewer demand characteristics, allowing for more natural behavior.
• How do field experiments compare to lab experiments in terms of control?


  Field experiments have less control over the situation compared to lab experiments.
• What is one reason why field experiments are considered less artificial?


  They occur in natural settings, reflecting real-life situations.
• Why do field experiments have higher ecological validity than lab experiments?


  Because they measure behavior in real-world contexts.
