Inquiries into Human Faculty and Its Development. In the past people tend to have very clear ideas about what was appropriate to each sex and anyone behaving differently was regarded as deviant. Today we accept a lot more diversity and see gender as a continuum i. Gender is determined by two biological factors: hormones and chromosomes. Hormones are chemical substances secreted by glands throughout the body and carried in the bloodstream.
The same sex hormones occur in both men and women, but differ in amounts and in the effect that they have upon different parts of the body. Testosterone is a sex hormone, which is more present in males than females, and affects development and behavior both before and after birth. Testosterone, when released in the womb, causes the development of male sex organs at 7 weeks and acts upon the hypothalamus which results in the masculinization of the brain. Testosterone can cause typically male behaviors such as aggression, competitiveness, Visuospatial abilities, higher sexual drive etc. An area of the hypothalamus at the base of the brain called the sexually dimorphic nucleus is much larger in male than in females. At the same time testosterone acts on the developing brain.
The brain is divided into two hemispheres, left and right. In all humans the left side of the brain is more specialised for language skills and the right for non-verbal and spatial skills. Shaywitz et al used MRI scans to examine brain whilst men and women carried out language tasks and found that women used both hemispheres, left only used by men. It appears that in males brain hemispheres work more independently than in females, and testosterone influences this brain lateralization.
Quadango et al. Young changed the sexual behavior of both male and female rats by manipulating the amount of male and female hormones that the rats received during their early development. A number of non-reproductive behaviors in rats are also effected by testosterone exposure around birth. These included exploratory behavior, aggression and play.
Young believed that the exposure had changed the sexually dimorphic nucleus SDN in the brain, as male rats had a larger SDN than females. The results have proven to be highly replicable. Because this study was conducted in a lab it has low ecological validity. For example, in the lab hormones are injected in one single high dose. Whereas in real life, hormones tend to be released by the body in pulses, in a graduated fashion. Therefore, the results might not be generalizable outside of the lab, to a more naturalistic setting. Ultimately psychologists must ask themselves whether in their research the ends justify the means. By this we mean that all research using human or non-human animals must be considered in terms of the value of the results when compared to the cost both moral and financial of carrying out the work.
The main criterion is that benefits must outweigh costs. But benefits are almost always to humans and costs to animals. We should be cautious when extrapolating the results of animal research to a human population. This is because the physiologies e. Also, the social and cultural variables within a human population are more complex when compared to social interactions between rats. The consequence of this means the external validity of the research is uncertain. However, a study by Hines suggests it might be possible to generalize the results to humans. Hines studied female babies born to mothers who had been given injections of male hormones during pregnancy to prevent miscarriage. They were found to be more aggressive than normal female children. Hines concluded that the extra testosterone in the womb had affected later behavior.
The normal human body contains 23 pairs of chromosomes. Being gay is now considered a genetic phenomenon rather than being influenced by the environment. This is based on observations such as:. More recent studies have indicated that both gender and sexuality are spectrums rather than strictly binary choices. Genetics is a complex and evolving field. A relatively newer idea in genetics is the epigenome. Changes happen to DNA molecules as other chemicals attach to genes or proteins in a cell. These changes constitute the epigenome. The epigenome regulates activity of cells by "turning genes off or on", i. This is why even though all cells have the same DNA or genome , some cells grow into brain cells while others turn into liver and others into skin.
Epigenetics suggests a model for how the environment nurture may affect an individual by regulating the genome nature. More information about epigenetics can be found here. It is sometimes a question whether the "trait" being measured is even a real thing. Much energy has been devoted to calculating the heritability of intelligence usually the I. If genes do contribute substantially to the development of personal characteristics such as intelligence and personality, then many wonder if this implies that genes determine who we are.
Biological determinism is the thesis that genes determine who we are. Few , if any, scientists would make such a claim; however, many are accused of doing so. Others have pointed out that the premise of the "nature versus nurture" debate seems to negate the significance of free will. More specifically, if all our traits are determined by our genes, by our environment, by chance , or by some combination of these acting together, then there seems to be little room for free will. This line of reasoning suggests that the "nature versus nurture" debate tends to exaggerate the degree to which individual human behavior can be predicted based on knowledge of genetics and the environment.
Furthermore, in this line of reasoning, it should also be pointed out that biology may determine our abilities, but free will still determines what we do with our abilities. Share this comparison:.
