Intelligence testing has been an integral part of psychological assessment for over a century. Different theories and methods have influenced the development of these tests. One such pivotal concept in intelligence testing is the idea of 'g' or general intelligence, proposed by Charles Spearman. According to this theory, 'g' represents a single underlying factor that contributes to a variety of cognitive tasks. However, later theories, such as Howard Gardner's Multiple Intelligences theory, challenge this notion by introducing the idea that intelligence is not a singular construct but a combination of various abilities.
