Physical development. By this age, infants may have doubled their birth weights. They typically grow about 0.8 inches (2.0 cm) and gain about 1 to 1.5 pounds (450 to 680 g) during this month. [28] Fat rolls ("Baby Fat") begin to appear on thighs, upper arms and neck. Motor development. May be able to roll from front to back. [29]
Gesell found asymmetric development to be common in children. [11] In motor behaviors, this can be seen in an infant’s tonic neck reflex, where babies prefer to lie with their heads turned to one side and extend their arm to the same side which the head is turned while flexing the other arm behind their head. It is a reflex where the infant ...
The Gesell Developmental Schedules claimed that an appraisal of the developmental status of infants and young children could be made. The Gesell Developmental Schedule believes that human development unfolds in stages, or in sequences over a given time period. These stages were considered milestones, or the manifestations of mental development. [1]
Physical development refers to the development of movement, the brain and all other relevant stages of development that contributes to locomotion. [7] In early childhood, children develop the ability to gradually control movement, achieve balance and coordination and fine and gross motor skills. [8]
Atypical motor development such as persistent primitive reflexes beyond 4–6 months, or delayed walking may be an indication of developmental delays or conditions such as autism, cerebral palsy, or down syndrome. [53] Lower motor coordination results in difficulties with speed accuracy and with trade-off in complex tasks.
The model provides a graphic representation of the Synactive Theory of development, as applied to both fetal and newborn stages. It focuses upon the infant's within-organism, four subsystems of functioning, and their continuous interaction with each other and with the environment across time (i.e., “together in action,” or synaction).
Piaget thought that an infant's perception and understanding of the world depended on their motor development, which was required for the infant to link visual, tactile and motor representations of objects. According to this view, it is through touching and handling objects that infants develop object permanence. [2]
In Thelen's view behavior emerges as a pattern from all the streams that flow into the river of infant development. Or, as she wrote "The mind simply does not exist as something decoupled from the body and experience". [6] She suggested that an infant already has basic motor patterns at birth as demonstrated by stepping reflex and spontaneous ...
