Heredity and hormones participate in key roles in human behavior. The nervous and the endocrine system collaborate in a constant chemical conversation with the endocrine system aiding in coordinating and incorporating multifaceted psychological responses. In this essay, I will contrast and compare the control of heredity and hormones on human behavior. I will also incorporate a discussion on the endocrine system, recognition of hormones and the glands accountable for secreting them, and genetics, behavior genetics, and evolutionary psychology.
Several factors influence the manner in which the human behavior grows particularly hormones and heredity. Individuals are molded by life incidents and how they respond to those occurrences can be attributed to hormones and hereditary. Human behavior differs from person to person. The propensities to commit felonies, be extra violent or to be cleverer are all pointers of human conduct. Biologically, these behavioral effects are a straight consequence of hormones and genetic materials. The relation connecting these two characteristics shall be scrutinized underneath (Dean Copeland, 2009)
Currently, Heredity cannot be controlled. Individuals inherit specific genes from both parents. This amalgamation of genes generates a completely fresh genetic mixture that is exclusive to the person. Many traits can be accredited to heredity for example; beard on an individual's face can be credited to a genetic material that the person’s parent had. Conversely, physical characteristics are not the only characteristics that can be accredited to parent's genes. An individual with schizophrenia, depression, and anxiety have a propensity to posses a family history. Consistent with Morris and Maisto (2005), the families of schizophrenic people are approximately ten times more probable to have the condition than an individual selected arbitrarily from the general populace would. Like some physical characteristics, the tendency to psychological sickness does not constantly state whether the individual will acquire the illness. Having a family history with the sickness merely augments the probabilities that the same ailment will be perceptible inside the family. Recognizing explicit genes that cause hostility for instance, are intricate to bond to a definite gene. Several researches that have endeavored to discover a precise connection or gene arrangement that generates a behavior however since conduct has several environmental aspects, these explorations have not been flourishing. Researches have been supplementary successful in discovering a connection linking absent or additional chromosomes with definite illness and physical deformities.
Hormones are accountable for several human tasks, which comprise sexual want, development, growth, reproduction, and metabolism. Hormones in addition have an enormous effect on human behavior, particularly mood. Several individuals merely become responsive to hormones at the commencement of puberty. The body experiences physical and chemical transformations. Physical characteristics like pubic hair emerges and emotional variations become evident. The endocrine system, comprising the pituitary gland, the pineal gland, the parathyroid gland, the thyroid gland, the pancreas, the ovaries and gonads, is in charge for liberating hormones. Every gland secretes a specific hormone accountable for different body purposes. For instance, the thyroid gland secretes thyroxin, accountable for metabolism (Van Holde and Mathews, 2010). The thyroid gland is also accountable for several human behaviors. A hyperactive thyroid can generate several symptoms: insomnia, fatigue, agitation, and abridged attention span (Morris and Maisto, 2005). Estrogen and testosterone hormones produced by the testes and ovaries respectively, also affect human behavior. They are accountable for sexual desire however play different roles. Testosterone has also been accredited to producing violence. Men characteristically have an elevated testosterone intensity therefore are more probable to be hostile than women. On the other hand, Women have elevated estrogen intensities than men and undergo several hormonal variations all through the month. It is highest at ovulation and triggers excitement. It is lowest at the menses with women being bad-tempered and depressed. Any hormonal variation can create an alteration in behavior (Faraone, et al., 2009).
Heredity can have an influence on human behavior providing the conditions are exact. On the other hand Hormones, do have an influence on human behavior. They do not require ecological controls to have an influence on behavior. Heredity and hormones jointly assist to generate personalities that are exclusive to each person.
