How do humans react to the ferocious roar of the bear? Why do humans have headaches and stress out when come upon to do certain tasks? The environment, genes and chromosomes, and the central nervous system are factors to answer these questions. The human psychological characteristics and behavior are built by a combination of these factors. Psychologists use these factors to determine peoples psychological makeup and behavior. However, a persons characteristics come primarily from their genes. From the time the baby gets out into the real world inherited genes are making the baby act in a certain way. When someone tickles them, they might cry or laugh.
Their genes establish their reaction to these events. From the beginning of birth, the babys reaction to the environment can only be determined by its genes. As a result, human behavior uses a combination of environmental and inherited trait factors. The central nervous system connects the brain and spinal cord together. Without them humans could not send or receive information from other parts of the body. When the genes send a message the endocrine system secretes thyroid gland. Then, the thyroid gland secretes hormones to influence the growth of the brain; thus, a combination of genes and the nervous system determine the humans psychological characteristics.
Many important traits are highly inherited like IQ and height. A person can raise their IQ during a span of time, but they will never have a high IQ unless they were born with one. Genes influence human behavior for fifty percent, the rest being based on environmental factors. Scientists should put genes in a fifty-plus percent group since they determine a humans reaction to environmental factors. Thus, genes have a greater impact on how humans look at the world and environment. The environment is an important factor to human development in growth and behavior.

In The Colorado Adoption Project, a study found that the resemblance on general cognitive ability between adopted children and their birth parents increased from ages three to sixteen. As a result, the environment plays a huge part during this age. From ages seventeen and up, the environment plays a smaller role since the brain has stopped development of brain cells. Instead, the brain grows by synapses and bridges. All these behavioral factors are determined by doing studies on mostly children. Scientists enjoy taking identical twins, putting them in different environments, and testing them to discover any changes. Plomin states that the most psychologically relevant environmental influences are those that make children different from one another. Researchers measure the influence of genetics throughout a life span during their study.
The combination of genes with other factors determines the humans psychological behavior and characteristics. Researchers study behavior by looking at genes to determine how it affects human growth. The environment influences humans the most during the youth, while genes are always becoming a bigger influential factor to human life. Although genes account for fifty percent of human behavior, they play a much bigger role than the environment. Just remember, genes should be placed in a fifty-plus percent category since they contribute the most to human makeup and behavior..
