Final answer:
Structuralism, which is not active today, will not be included in the display, unlike behaviorism, functionalism, and Gestalt psychology, which continue to influence modern psychological research.
Step-by-step explanation:
The school of thought that will NOT be in the display because it is not active or continuing to develop today is Structuralism. While behaviorism, functionalism, and Gestalt psychology have all influenced modern psychology and are still considered relevant, structuralism has not had the same lasting impact. Behavioral perspectives, including behaviorism, logical behaviorism, and semantic behaviorism, emphasize the study of observable behavior and continue to evolve, especially within areas like cognitive-behavioral therapy and behavioral economics.
Similarly, Gestalt psychology's focus on perception and its principles are influential in modern studies on sensation and cognition. Meanwhile, structuralism, which aimed to break down mental processes into their most basic elements, is considered a historical standpoint and is not a focus in contemporary research.
