Answer :
All three dimensions of temperament are stable from early childhood to middle childhood.
What is mean by temperament?
Temperament, as used in psychology, broadly refers to consistent individual variances in behavior that have biological roots and are mostly unrelated to learning, a set of guiding principles, or attitudes.
A correlation between temperament and formal dynamical properties of behavior, such as energetic aspects, flexibility, sensitivity to particular reinforcers, and emotionality, has been suggested by several researchers.
Temperament traits (like Neuroticism, Sociability, Impulsivity, etc.) are distinct patterns of behavior that can be observed throughout a person's lifetime, but they are most obvious and extensively researched in young children. Although longitudinal research in the 1920s started to establish temperament as something that is stable across the lifespan, temperament is typically used to describe babies.
