Monozygotic

have proposed several causative factors, including but not limited to genetic factors, viruses and toxins and pollution. It has been hypothesized that genetics play a role in the acquisition of autism because when compared to fraternal twins, both monozygotic are twice as likely to have autism. Studies have also suggested that autism may be due to a compromised immune system. Evidence also suggests that viruses may play a role in causing autism; after being exposed to rubella during the first…

conducted family studies on homosexuality and discovered homosexual men have more homosexual brothers than heterosexual brothers. In contrast, Kallman (1952) conducted a twin study. Results portrayed a 100percent concordance rate for thirty seven male monozygotic pairs in comparison to the 15 percent for dizygotic pairs. Nonetheless, this study was severely criticised for the unequal level of participants. Subsequent twin studies have produced varied and inconsistent results. Bailey (1995)…

Both behaviorism and evolutionary psychology differ from others on the spectrum in that they are both extremes, and the creation of the two fields resulted directly from the nature vs. nurture question. Despite this, modern psychologists disagree with the “all or nothing” mentality that both extremes of the spectrum pose. Instead, the question has been rephrased to “How much does each role play in development?” Given that both nature and nurture play a valuable part in acquired characteristics…

The evidence of intelligence being nature or nurture has been debated for decades. The nature’ side of the debate argues that a persons mental ability is based on what he/she is born with genetically. Likewise, to say that a person’s genetics solely establishes their mentality is to say that the environment in which one lives has no influence at all. On the other hand, the nurture side of the debate argues that intelligence is caused by a persons environment. To determine this, we will examine…

person’s human development. In fact, only fifty percent of personality tendency was observed to be genetic in a 1994 study by observing the five-factor model of personality- extraversion, neuroticism, conscientiousness, agreeableness, and openness- in monozygotic and dizygotic twins (Bouchard, 1994). According to Erikson’s theory of psychosocial development, there are eight stages that every person goes through that, if not fulfilled, could cause problems later in life. Because he relies on the…

The rate of obesity varies in different regions of the world, which indicates that there are different reasons causing this disease. France is less affected by obesity in comparison to U.S; therefore, by comparing these two countries one can find out why there is a huge increase in the rates and the factors affecting this growth in rates. The price of a meal and how convenient it is to find food has a crucial role in the development of a nation’s lifestyle. The cost of buying a meal from…

Evaluate the contribution of Psychological Perspectives in the treatment of specific behaviours, states of consciousness and emotional states that are associated with OCD. Intro Obsessive-compulsive disorder (OCD) is an anxiety-related condition. OCD evokes anxiety provoking thoughts (compulsions) and repetitive behaviour (obsessions). Psychological perspectives have different theories with regards to how OCD occurs and is treated. This essay evaluates the treatments used in one particular…

Background Neurodevelopment is defined as “the dynamic inter-relationship between genetic, brain, cognitive, emotional, and behavioral processes across the developmental lifespan [1].” Neurodevelopmental disorders are defined as a group of conditions caused by damage to the neurological development process which cause long term delays in development. These disorders normally begin in infancy, when development is most crucial, and remain fairly consistent throughout adulthood. Neurodevelopmental…

heterosexual. This supports the theory of the genetic link to homosexuality along with the study done by Kenneth Kendler in 2000 who analyzed the factors leading to homosexuality in twin siblings. They found that there was a higher probability for the monozygotic (have identical DNA structure) twins to be homosexual than dizygotic (only share half of their genes) twins or regular siblings (Robinson). With every study, homosexuality is progressively shifted from being seen as a choice to a…

Do you think a plant, animal, or even a human can be cloned? If so, would you be a support or oppose it? Genetic Cloning has many titles; from human cloning, Reproductive cloning, Therapeutic cloning or even Research cloning. They all mean the same thing, which is the process in which a gene of interest is located and copied out of DNA extracted from an organism. Genetic Cloning has been going on for years, ever since 1981. But, that was just plants and animals. Now today, the scientists and…
