Final answer:
A Skinner box is most often utilized in studies of operant conditioning, where behaviors are modified by their consequences, a method developed by B.F. Skinner.
Step-by-step explanation:
A Skinner box is most likely to be used in research on operant conditioning. Operant conditioning is a form of learning where an individual's behavior is shaped and maintained by its consequences. The introduction and removal of reinforcements or punishments following a behavior increase or decrease the probability of a behavior being repeated. Developed by psychologist B.F. Skinner, the Skinner box, or operant conditioning chamber, is a tool where animals such as rats can be studied. In these boxes, animals might find a lever that when pressed, delivers a food reward. Through successive interactions, the animal learns to associate pressing the lever (a voluntary behavior) with receiving food (a consequence), thereby illustrating operant conditioning.
