A researcher wants to design a study following the experimental analysis of behavior to investigate how a new reward schedule affects the lever-pressing behavior of an organism. In one to three sentences, describe the key research design choice and the type of variables the researcher must focus on to align with this subfield.

Question: A researcher wants to design a study following the experimental analysis of behavior to investigate how a new reward schedule affects the lever-pressing behavior of an organism. In one to three sentences, describe the key research design choice and the type of variables the researcher must focus on to align with this subfield.

Sample answer: The researcher must use a single-subject research design to study the organism individually over time. They must focus on how the external factor, which is the reward schedule, systematically influences the target behavior of lever-pressing over an extended period.

Key points:

  • Specify the use of a single-subject research design rather than a group design.
  • Focus on how external factors (rewards/punishments) systematically influence behavior.
  • Observe and measure the target behavior over time.

Rubric: The answer must apply the principles of the experimental analysis of behavior by specifying that a single-subject design should be used, the independent variable must be an external factor (the reward schedule), and the behavior must be tracked systematically over time to observe the influence.
