Basic Research
As opposed to applied research, basic research is conducted with the intent of increasing the scientific knowledge base, and to find theoretical truth and understanding (not specifically to solve practical problems). For example, someone conducting basic research on cheating behavior may design a study examining whether students from divorced families cheat more often than students not from divorced families. Notice that the research is not done to reduce cheating, help people who cheat, or any other "applied" aspect, but to increase the understanding of cheating behavior.
