Location of research

• A lab experiment establishes cause and effects as there are 2 controls of iv. It is also a controlled experiment.
• Positive of a lab expeirment:

  Its ev's and cv's can be controlled

  The study is replicable (standardised procedure)

  Experienter has control and can establish cause and effect
• Negatives of a lab experiment:

  Participants could guess the aim

  It's in an unrealistic setting so results may not be appliable
• A field experiment is done in a natural environment which established cause and effect
• Positives of a field study:

  Its a real life situation which means it has high real mundane realism

  They are reduced demand characteristics
• Negatives of field study:

  Hard to control ev's and cv's

  Ethical issuse may occur
• Online research is reaserch which is gathered from online resources,for example, questionaires.
• Positives of online research:

  Theres a large sample

  Diverse group able to answer

  A lot cheaper
• Negatives of online research:

  Biased sample

  Easy to lie which would affect ecological validity
• A Quasi experiment is where the iv isn't under direct control of the researcher
• A difference study is a study that compares two groups of participants and looks for differences between them, for example, gender, age , anxiety
• A natural experiment is when the IV is not manipulated by the researcher, but is naturally occurring
• Positives of quasi experiments:

  Allows us to research real-life problems
• Negatives of quais experiments:

  Difficulty for replication

  Participants can't be randomly assigned
• Advantages of field based studies include naturalistic observation (participants behave as they would normally) and ecological validity (results apply to real life situations)
• Field based studies are conducted outside of the lab, where participants are observed behaving naturally in their own environments
• Lab based studies are conducted in an artificial environment, which can be controlled to ensure that the variables being tested have no other influence on them
