PHYSICAL DEVELOPMENT
Physical development is the first form of maturation that parents detect, and it is the easiest to determine. Gross motor development refers to a child's ability to move and use the various parts of her body. Motor development occurs when the child rolls over, crawls, walks and interacts with her environment. Parents should examine their child's muscle tone, strength and range of movement to determine if they are developing properly.
Fine motor development refers to precise and intricate movements as when a child uses his tongue to speak, his fingers to complete elaborate tasks or his muscle groups to cooperate and perform full-body motions like dancing. Concerning early milestones, a child should be able to sit unassisted at 8 months; pull up to a standing position at 10 months; walk, climb and use utensils at 2 years; and complete simple puzzles, kick balls and ride a tricycle at 3 years.
COGNITIVE DEVELOPMENT
Cognitive development is a bit more difficult to detect because it encompasses learning, memory, perception, language, problem solving and other mental processes. Jean Piaget, famed developmental psychologist, defines child cognitive development in four stages. In the sensorimotor stage (birth to 18 months), infants primarily interact with the world through actions such as touch, tactile exploration and facial expression. The preoperational stage (2 to 7 years) is a period when children begin to symbolize objects and personify items. Their thoughts are influenced by fantasy since they have difficulty conceptualizing time and seeing things from other people's viewpoints.
The concrete stage (7 years to adolescence) introduces children to abstract thoughts and rational judgments. Children are better able to understand complex issues without the need for physical examples. Lastly, the formal operations stage (adolescence to adulthood) brings the child's mental development to fruition. Besides being able to use hypothetical and deductive reasoning, children are capable of assessing concepts from multiple perspectives.
PSYCHOSOCIAL DEVELOPMENT
Psychosocial development addresses interpersonal maturation including the formation of peer and family relationships, motives, emotions, roles, identity and personality traits. Psychoanalyst Erik Erikson conceptualized the most comprehensive theory addressing this form of development. According to his theory, personality unfolds in a series of stages defined by resolving conflicts that arise from unmet needs. Although there are eight stages, only five will be discussed herein.
The first stage (birth to 18 months) determines whether children will have a trusting or untrusting perception of others depending upon how well their caregivers meet their basic needs. The second stage (2 to 3 years) determines whether children will have a confident or insecure outlook depending upon how well they master essential life tasks. The third stage (3 to 5 years) determines whether children will feel purpose and take initiative or be frozen by guilt depending upon how well they learn to influence their environment. The fourth stage (6 to 11 years) determines whether children feel competent or inferior depending upon how successful they are at meeting social and academic demands. Finally, the fifth stage (12 to 18 years) determines whether children develop a sense of identity or experience role confusion depending upon how well they navigate social interactions.
NATURE VERSUS NURTURE
Each form of development is imbedded in the psychological debate known as "nature versus nurture." "Nature" refers to genetic and biological predispositions that relate directly to muscular, hormonal and brain development. Those who believe development is strictly the product of genetic or biological causes assume that child maturation is largely hereditary and physiological, meaning that parental actions have little to no influence over developmental outcomes.
Conversely, "nurture" refers to change in response to environment, which encompasses learning, experiences and social interaction. Neither side of the debate can claim absolute accuracy. Otherwise, children reared in similar environments or with similar genetics would all achieve developmental milestones at similar times. This is simply not the case. Instead, it is more likely that nature and nurture contribute to development in the form of a delicate balance between environmental learning and inherited traits.
