Dr. Arnold Gesell is associated with the maturational perspective of motor development.
They are motor characteristics, personal hygiene, emotional expression, fears and dreams, self and sex, interpersonal relations, play and pastimes, school life, ethical sense, and philosophic outlook. Gesell became specialized in the "maturational" perspective. He believed that the development was predetermined.
As Gesell developed his maturation theory, he felt that the psychological processes could develop in fixed sequences just as the physical body of a child develops in a fixed sequence. The heart of an embryo, for example, is the first organ to develop every time. Then the central nervous system begins to develop. Peripheral organs then develop afterward.
Gesell also noted that infants gain control over their bodies after birth in a series of fixed sequences. Their lips and tongues gain control first, then eye movement, then gradual control over the shoulders, neck, and limbs. There is a consistent head-to-toe trend in human development.
