What is the primary nature of temperament in infants?

The primary nature of temperament in infants is predominantly biologically driven and determined. Temperament refers to the inherent characteristics that define a child's approach to the world, including their mood, activity level, and emotional reactivity. Research indicates that these traits are largely influenced by genetics and biological factors rather than acquired through experiences or interactions.

While environmental influences can shape how a child's temperament is expressed, the core attributes of temperament are consistent from early infancy, suggesting a strong biological basis. This understanding emphasizes that temperament forms a significant part of a child's individuality early in life and is not something that is simply learned or solely shaped by their surroundings.
