Concept of Intelligence

Intelligence is the mental ability to learn, reason, solve problems, and adapt to new situations. It involves understanding the world, thinking rationally, and using knowledge effectively. Psychologists study intelligence to understand why people differ in their learning, creativity, and everyday problem-solving abilities, making it a key factor in achieving success in life.

• According to Lewis Terman, “An ability to think on an abstract level is called Intelligence.”
• According to David Wechsler, ‘Intelligence is the aggregate or global capacity of an individual to act purposefully, to think rationally, and to deal effectively with his environment.’
• According to Binet (1905), “Intelligence refers to comprehension, intention, direction, and criticism.”
• According to Wyatt, “Intelligence is the power of apprehending the relationship between things.”
• According to Stern, “Intelligence is a general mental adaptability to new problems and conditions.”
• Spearman (1904), “Intelligence is the capacity for constructive thinking, a discovery of appropriate qualities and relations of the ideas that are before us.”
• According to Thurstone (1930), “Intelligence consists of many primary abilities.”
• Thus, Kimbel and Germazy state, “Intelligence consists of the abilities that a society values, because they are useful in meeting the society’s current needs. When these needs change, the abilities that define intelligence change.”

• Multi-dimensional: Intelligence is not limited to academic skills; it includes social, emotional, and practical abilities.
