Final answer:
Charles Spearman is the psychologist who did not suggest the existence of more than one kind of intelligence, as he focused on a single general intelligence factor called 'g'. Unlike Spearman, psychologists Gardner, Sternberg, and Guilford each proposed theories that recognized multiple forms or aspects of intelligence.
Step-by-step explanation:
The psychologist who did not suggest the existence of more than one kind of intelligence is E. Spearman. Charles Spearman proposed that intelligence consisted of one general factor, known as g, which represents general intelligence. In contrast, Gardner proposed the theory of Multiple Intelligences, which included various distinct types of intelligence such as linguistic, logical-mathematical, and spatial intelligence, among others. Sternberg developed the Triarchic Theory of Intelligence, which encompasses practical, creative, and analytical intelligence. Guilford also contributed to the understanding of intelligence with his structure of intellect model, which included multiple dimensions of intelligence.
On the other hand, Spearman's theory was focused on the commonalities among different cognitive abilities and downplayed the unique aspects of each ability. His singular view of intelligence as a general cognitive ability stands in contrast to multiple-intelligence theories.
