72 What are Intelligence and Creativity?
The child points to the words on the new page and reads aloud, “Go, Pig! Go!” The parent stops and looks at their child. “Can you read that?” the parent asks. “Yes, I can!” the child responds. The child then points to the words and reads again, “Go, Pig! Go!”
The parent was not actively teaching their child to read, even though the child constantly asked questions about letters, words, and symbols that they saw everywhere: in the car, in the store, on the television. The parent wondered about what else their child might understand and decided to try an experiment. “Big, small, dog, bird, bed, truck, car, tree,” the child read, slowing down to carefully pronounce bird and truck. Then, “Did I do it?” “You sure did! That is very good.” The parent gave their child a warm hug and continued reading the story about the pig, all the while wondering if their child’s abilities were an indication of exceptional intelligence or simply a normal pattern of linguistic development. Like the parent in this example, psychologists have wondered what constitutes intelligence and how it can be measured.
Classifying Intelligence
What exactly is intelligence? The way that researchers have defined the concept of intelligence has been modified many times since the birth of psychology. British psychologist Charles Spearman believed intelligence consisted of one general factor, called g, which could be measured and compared among individuals. Spearman focused on the commonalities among various intellectual abilities and de-emphasized what made each unique. Long before modern psychology developed, however, ancient philosophers, such as Aristotle, held a similar view (Cianciolo & Sternberg, 2004).
Others psychologists believe that instead of a single factor, intelligence is a collection of distinct abilities. In the 1940s, Raymond Cattell proposed a theory of intelligence that divided general intelligence into two components: crystallized intelligence and fluid intelligence (Cattell, 1963). Crystallized intelligence is characterized as acquired knowledge and the ability to retrieve it. When you learn, remember, and recall information, you are using crystallized intelligence. You use crystallized intelligence all the time in your coursework by demonstrating that you have mastered the information covered in the course. Fluid intelligence encompasses the ability to see complex relationships and solve problems. Navigating your way home after being detoured onto an unfamiliar route because of road construction would draw upon your fluid intelligence.
Other theorists and psychologists believe that intelligence should be defined in more practical terms. For example, what types of behaviours help you get ahead in life? Which skills promote success? Think about this for a moment. Being able to recite all 45 presidents of the United States in order is an excellent party trick, but will knowing this make you a better person?
