Research methods- Types of Experiments

• What are the different types of experiments discussed in the video?

  Lab, field, natural, and quasi experiments
• Why might terminology in research methods be intimidating for beginners?

  Because they may not know many of the terms and definitions
• What is the recommended approach for watching the research methods videos?

  • Watch once without taking notes
  • Watch again while pausing to write down key ideas
• What is a laboratory experiment?

  A controlled experiment typically set in a lab environment
• What is the main principle of a lab experiment regarding variables?

  Only one independent variable changes while all others are controlled
• In a lab experiment, what is the independent variable?

  The factor that is manipulated by the experimenter
• Why is high control in lab experiments beneficial?

  It allows for confident suggestions of cause and effect relationships
• What does high internal validity in lab experiments indicate?

  The observed effect is real and due to the independent variable
• What is a disadvantage of lab experiments regarding ecological validity?

  Lab conditions may not generalize to real-world environments
• What is meant by mundane realism in lab experiments?

  The tasks used may not reflect real-world activities
• What are demand characteristics in lab experiments?

  Participants may change their behavior based on what they think is expected
• What is a field experiment?

  An experiment conducted in a natural setting
• What is a key strength of field experiments?

  They have increased external validity due to naturalistic behavior
• How do field experiments address demand characteristics?

  Participants are less likely to know they are being studied
• What is a disadvantage of field experiments regarding control?

  They lack control over extraneous variables
• What is a natural experiment?

  An experiment where the independent variable occurs naturally
• What is a strength of natural experiments?

  They allow research into areas that cannot be ethically manipulated
• Why do natural experiments have high external validity?

  Changes occur naturally in real life
• What is a limitation of natural experiments regarding cause and effect?

  Researchers cannot control for extraneous variables
• What is a quasi experiment?

  An experiment where participants cannot be randomly assigned
• What is a strength of quasi experiments?

  They allow study of factors that cannot be ethically manipulated
• What is a limitation of quasi experiments regarding confounding variables?

  Differences between groups may affect the results
• What are the strengths and weaknesses of lab, field, natural, and quasi experiments?

  Lab Experiments:

  • Strengths: High control, high internal validity, replicable
  • Weaknesses: Low ecological validity, lack of mundane realism, demand characteristics

  
  

  Field Experiments:

  • Strengths: High ecological validity, naturalistic behavior, reduced demand characteristics
  • Weaknesses: Low control, extraneous variables

  
  

  Natural Experiments:

  • Strengths: Ethical research, high external validity
  • Weaknesses: Low control, difficult to establish cause and effect

  
  

  Quasi Experiments:

  • Strengths: Necessary for certain studies
  • Weaknesses: Confounding variables may affect results
• What resources are available for students and teachers on psych.com?

  Printable resources and tutorial videos
• How does the support from patrons benefit the creation of educational content?

  It allows the creator to teach part-time and produce more content
• What is the purpose of the psych boost workbook?

  To help students take notes and follow along with the videos
