types of experiments

• What types of experiments are discussed in the video?

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

  Many terms may be unfamiliar to beginners
• What is the purpose of the psych boost workbook mentioned?

  • Contains 150 full-color worksheets
  • Covers all compulsory units
  • Available on Amazon and the website
• What is the main principle of a lab experiment?

  Full control over environmental factors
• What is a laboratory experiment?

  An experiment conducted in a controlled environment
• What is the independent variable in a lab experiment?

  The factor that is changed by the experimenter
• Why is it important to control variables in a lab experiment?

  To ensure a cause and effect relationship
• How might changing the color of light affect recall in a lab experiment?

  It serves as an independent variable
• What does high internal validity in lab experiments indicate?

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

  They may not generalize to real-world settings
• What is meant by ecological validity?

  The extent to which findings can be generalized
• What is mundane realism in the context of lab experiments?

  The tasks used are not like real-world activities
• What are demand characteristics in a lab experiment?

  Participants change behavior due to expectations
• What is a field experiment?

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

  Increased external validity and natural behavior
• How do field experiments address demand characteristics?

  Participants are often unaware of the study
• What is a disadvantage of field experiments?

  Lack of control over extraneous variables
• What is a natural experiment?

  The researcher measures changes in naturally occurring variables
• What is a strength of natural experiments?

  They allow research in ethically sensitive areas
• Why might natural experiments have high external validity?

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

  Researchers have no control over variables
• What is a quasi experiment?

  An experiment without random assignment of participants
• Why might quasi experiments be necessary?

  Some factors cannot be randomly assigned
• What are confounding variables in quasi experiments?

  Differences between groups that affect results
• What are the strengths and weaknesses of each type of experiment discussed?

  Strengths:

  • Lab: High control, replicable, clear cause-effect
  • Field: Increased external validity, natural behavior
  • Natural: Ethical research, high external validity
  • Quasi: Necessary for certain factors, real-world relevance

  
  

  Weaknesses:

  • Lab: Low ecological validity, demand characteristics
  • Field: Lack of control, extraneous variables
  • Natural: No control, difficult to establish cause-effect
  • Quasi: Confounding variables, no random assignment
• What resources are available for students on psych.com?

  Printable resources and tutorial videos
• How does support from patrons benefit the creator of the videos?

  It allows part-time teaching and content creation
• What is the focus of the next video mentioned?
