In this section, we explore the various aspects of intelligence, emphasizing individual differences in psychological attributes. We begin by defining intelligence and discussing its meaning, which varies among cultures. Key theorists, such as Gardner and Sternberg, have proposed different theories, including Multiple Intelligences and the Triarchic Theory, which contribute to a broader understanding of intelligent behavior. The section also examines the implications of emotional intelligence, which includes the ability to manage one's feelings and those of others. Ultimately, we analyze the cultural context that shapes our perceptions of intelligence and how it influences everyday life and learning. The importance of distinguishing between intelligence and aptitude is also addressed, highlighting their roles in personal development and academic success.
