Piaget's theory of cognitive development assumes that mental development is a process that is directed by maturation and experiences like the environment. Piaget also suggests that, as children get older, genetic factors play a decreasing role, however the environments impact on cognitive development rises.
Nature versus nurture Although developmental change runs parallel with chronological age,  age itself cannot cause development. Environmental factors affecting development may include both diet and disease exposure, as well as social, emotional, and cognitive experiences.
Plasticity of this type can occur throughout the lifespan and may involve many kinds of behavior, including some emotional reactions. Genetic-environmental correlations are circumstances in which genetic factors make certain experiences more likely to occur. In all of these cases, it becomes difficult to know whether child characteristics were shaped by genetic factors, by experiences, or by a combination of the two.
What relevant aspects of the individual change over a period of time? What are the rate and speed of development? What are the mechanisms of development — what aspects of experience and heredity cause developmental change?
Are there typical individual differences in the relevant developmental changes? Are there population differences in this aspect of development for example, differences in the development of boys and of girls?
Empirical research that attempts to answer these questions may follow a number of patterns. Initially, observational research in naturalistic conditions may be needed to develop a narrative describing and defining an aspect of developmental change, such as changes in reflex reactions in the first year.
Such studies examine the characteristics of children at different ages. Some child development studies examine the effects of experience or heredity by comparing characteristics of different groups of children in a necessarily non-randomized design.
Child development stages Milestones are changes in specific physical and mental abilities such as walking and understanding language that mark the end of one developmental period and the beginning of another. Studies of the accomplishment of many developmental tasks have established typical chronological ages associated with developmental milestones.
However, there is considerable variation in the achievement of milestones, even between children with developmental trajectories within the typical range. Some milestones are more variable than others; for example, receptive speech indicators do not show much variation among children with typical hearing, but expressive speech milestones can be quite variable.
Prevention of and early intervention in developmental delay are significant topics in the study of child development. An example of a milestone would be eye-hand coordination, which includes a child's increasing ability to manipulate objects in a coordinated manner.
Increased knowledge of age-specific milestones allows parents and others to keep track of appropriate development. The Heckman's chart shows that the highest return of investment in education is maximum during the early years age 1 to 3 years old and decreases to a plateau during the school-aged years and adolescence.
Here are descriptions of the development of a number of physical and mental characteristics. As stature and weight increase, the individual's proportions also change, from the relatively large head and small torso and limbs of the neonateto the adult's relatively small head and long torso and limbs.
Speed and pattern[ edit ] The speed of physical growth is rapid in the months after birth, then slows, so birth weight is doubled in the first four months, tripled by age 12 months, but not quadrupled until 24 months.
At birth, head size is already relatively near to that of an adult, but the lower parts of the body are much smaller than adult size. In the course of development, then, the head grows relatively little, and torso and limbs undergo a great deal of growth.
However, genetic factors can produce the maximum growth only if environmental conditions are adequate. Poor nutrition and frequent injury and disease can reduce the individual's adult stature, but the best environment cannot cause growth to a greater stature than is determined by heredity.Insights Into Learning: Area in a Fifth-Grade Math Class Shows fifth graders working in small groups to determine the area of an irregular shape within the context of an authentic activity.
Fifth grade boys and girls are often quite hostile to each other. This rudeness has a neurological excuse. A National Institute of Mental Health study recently revealed, via MRI scanners, that girl and boy brains, at this age, are wildly dissimilar in the structure of their cerebral cortexes.
Developmental psychology is the study of how psychological factors can influence our physical development.
The preoperational stage lasts from age 2 to age 7. Developmental Psychology. Grades and Stages of Development We found 2 items.

Piaget's theory is mainly known as a developmental stage theory. Special used in the psychological study of infants.
Developmental psychology is the scientific study of how and why human beings change over the course of their life. Originally concerned with infants and children, the field has expanded to include adolescence, adult development, For example, they study how children form friendships.
