Temperament refers to the innate characteristics that influence how individuals react to their environment and interact with others. It encompasses traits such as emotional stability, activity level, and sociability. These traits are often evident from a young age and can shape a person's behavior throughout their life. In psychology, temperament is often categorized into different types, such as easy, difficult, and slow-to-warm-up. These categories help in understanding how children and adults respond to stress, adapt to new situations, and form relationships. Recognizing one's temperament can aid in personal development and improve interpersonal interactions.
