Lab Experiments

• What are the advantages of conducting experiments?

  Higher degrees of control and easy replication
• Why is the level of control in experiments considered an advantage?

  It allows researchers to isolate variables and establish cause and effect relationships
• How do experiments establish cause and effect relationships?

  By manipulating the independent variable (IV) and observing its effect on the dependent variable (DV)
• What is ecological validity in the context of experiments?

  It refers to how well the results can be generalized to real-world settings
• What is a potential ethical advantage of experiments?

  Participants are informed about their involvement in the research
• What is experimenter bias?

  It occurs when the experimenter's involvement influences the results
• How does the artificiality of laboratory experiments affect their validity?

  The more artificial the setting, the less ecological validity the results may have
• What are demand characteristics in experiments?


  They refer to participants behaving differently because they know they are being studied
• How can ecological validity impact the results of an experiment?

  If participants behave differently in an experimental setting, the results may not generalize to real-world situations
• What are the advantages and disadvantages of conducting experiments?

  Advantages:

  • Higher degrees of control
  • Easy replication
  • Establish cause and effect relationships

  
  

  Disadvantages:

  • Experimenter bias
  • Demand characteristics
  • Limited ecological validity
