Heritability

subject, we bring together a clearer picture of ADHD and their interpersonal relationships. Biological Aspects of ADHD ADHD is predominantly a hereditary disorder. In most cases 70% – 80% of diagnoses are due to heritability. (Cunll., & Castells., Pg.372) In twin studies, heritability was found to be at around 80%. (Tripp & Wickens., P.580) However, other factors that can influence a child to have ADHD are low birth weight…

From the early in the 1900’s to now the characters actresses portray are thin individuals. In 1960”s the English introduced a model named “twiggy” very, very slim. The media ( newspapers, magazines, shows, advertisements ) has promoted beauty as being slim. The outcome of these advertisements has changed the world’s description of beauty. Young men want to date beautiful ladies ( those who are slim). the young ladies also want to be slim to find a date or to find a career in the modeling.To…

Along with various environmental factors, genetics has a very significant impact on childhood obesity that cannot be ignored. In recent years, a great deal of effort has been used toward pinpointing specific genes that contribute to obesity; however, only "22 gene associations supported by at least five positive studies" (Walley et al., 2006) have been identified. Which is a surprisingly low number, to say the least. According to Stunkard et al. (1986) "the genetic component [of obesity] is…

The punishment should be swift, certain, and proportionately severe regarding the crime that has been committed. The punishment or the threat of punishment can act as a deterrent; which are two different deterrence. There is general deterrence which is where one is supposed to learn from the punishment received by others. The second deterrence is the specific deterrence where someone so supposed to learn from punishment received by a certain individual just so the act of delinquency is not…

relapsing disorder that develops over time as a results of long-term use of psychoactive substances. The studies of McLellan and colleagues (2000) confirmed that drug dependence and other chronic conditions share common characteristics, such as heritability, complex etiology (genetics, environment), and increased risks of disability and premature death. Like hypertension or asthma, the addiction can be diagnosed, is treatable but not curable, and requires long-term changes in lifestyle.…

Genes are major contributors to many psychiatric diseases. “The intermediate phenotype concept represents a strategy for characterizing the neural systems affected by risk gene variants to elucidate quantitative, mechanistic aspects of brain function implicated in psychiatric disease.” An example would be using imaging genetics to illustrate recent advances, challenges and implications of linking genes. Urbanicity exposure is associated with corresponding changes in schizophrenia going in to…

drug or performing a certain action, which cause the pleasure sensors in the brain to become dependent on the drug or action. “Genetic factors account for roughly 50% of this individual variability in addiction vulnerability, and this degree of heritability holds true for all major classes of addictive drugs, including stimulants, opiates, alcohol, nicotine, and cannabinoids. It has not yet been possible to identify…

The purpose of this study is to demonstrate if success in academics or life can be predicted by a person’s degree of grit. The authors of this paper define grit as perseverance and passion for long-term goals as defined by Duckworth of University of Pennsylvania. At the time of this research there seems to be a lot of hype around grit since the department of education in the US and UK have been focusing on increasing student’s grit. Somewhere in the articles it states that previous research has…

Other evidence in support of the dopamine hypothesis relating to the substantia nigra include structural changes in the pars compacta. Some of the other changes in the substantia nigra include increased expression of NMDA receptors, and reduced dysbindin expression. Increased NMDA receptors may point to the involvement of glutamate-dopamine interactions in schizophrenia. Due to the changes to the substantia nigra in the schizophrenic brain, it may eventually be possible to use specific imaging…

A Bit of Both The ironic tale of Mary Shelley’s Frankenstein shows that the miserable and tragic fate of the protagonist, Victor Frankenstein, is the product of his nature. In his relentless quest to instill life upon inanimate objects, Frankenstein “deprived [himself] of rest and health” (Shelley 45), and “lost all soul or sensation but for this one pursuit” (Shelley 42). After his own invention murdered his closest family and friends, Victor vowed to revenge their deaths. He persistently…
