Why do you believe pyschologist study the whole lifespan?

Expert Solution

Psychologist study the whole lifespan because development happens at different stages in one's life and at every stage some new transformation of the individual happens which affects one's behaviour and personality.
Developmental psychologists study how people grow, develop and adapt at different life stages. They conduct research designed to help people reach their full potential — for example, studying the difference between learning styles in babies and adults.
They apply this knowledge to help people overcome developmental challenges and reach their full potential. Developmental psychologists study changes in human development across the lifespan, including physical, cognitive, social, intellectual, perceptual, personality and emotional growth.
It is important to study life span development because humans are living longer than ever before, and it is important for psychologists to understand every phase of human growth and development.
