Heritability

1. Bedbugs have evolved in the United States since the 1940s and 50s (Mitchell 2015). Due to genetic mutations after World War II a wide spread of pesticides known to be DDT were used. The genetic variation makes them resistant to the pesticides (Zimmer 2015). These DDT pesticides were used on the bedbug population, making them resistant to the pesticide. This illustrates natural selection because those resistant to the pesticide survive best. Which is heritable to their population with the…

The basic benefit of the artificial meta-analysis over the literature review is the possibility of producing a less partial measurable analysis of the conclusions of numerous major experimental studies. In regards to this specific experiment, the researchers attempted to use those principles that are primarily used for larger literature works. There was heavy usage of MEDLINE searches that were used to facilitate this article. In order to recognize all pertinent primary studies, computerized…

Post-Traumatic Stress Disorder: Peggy Case Study 1. Describe the causes of PTSD. Explain the symptoms and categories (re-experiencing, avoidance, and hyperarousal) of PTSD. Post-traumatic stress disorder is a psychiatric disorder influenced by an individual’s experience of extreme stress or trauma. It is a multifactorial disorder that inhibits the day-to-day functioning, workability and social communication of the individual diagnosed (Levin et al., 2014). Individuals diagnosed with…

increase in individual’s survival and reproduction rate (Whipps, 2009). Homo sapiens lethal violence has been increasing over the course of mammal evolution. The aggression in mammals, that includes humans, also has a genetic component with high heritability (Wrangham and…

In “For Whom The Bell Curve Tolls,” Robert J. Sternberg reviews The Bell Curve and gives his input on points such as the nature of intelligence, job performance, and IQ tests. The Bell Curve was one of the works by Richard Herrnstein and Charles Murray that showed the public a deeper view of psychological science. It begins with the topic of the general factor of intelligence and how it represents all the tests around intelligence. There were two disputes that followed along the general factor.…

A human’s cognitive ability is unlike any other animal on the earth. Compared to other animals, the human brain possesses more neurons and synapses, tallying eighty-six billion and one hundred fifty trillion respectively. The wiring of the brain and its connections are responsible for human’s superior cognition. Thus, the reason neuroscientists pursue research of neural connections is obvious; neural connections are the fundamental basis of individual expression. Many famous neuroscientists,…

Redman, L. M. (2011). Caloric restriction in humans: physiological, psychological, and behavioral outcomes. Antioxidants and Redox Signaling, 14 (2), 275-287. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3014770/ Calorie restriction can lead to many disorders such as abdominal obesity, insulin resistance, dyslipidemia, and hypertension or metabolic syndrome. Calorie restriction can, ironically, cause weight gain after dieting due to factors like a low metabolism, impaired fat oxidation, insulin…

Separation Anxiety Disorder Separation anxiety disorder (SAD) is characterized by persistent and frequent fears or worries that do not correspond to the norms of normal development (American Psychiatric Association, 2013). There is age inappropriate anxiety when the individual is separated from their attached figure, which causes significant distress and impartment to their life. SAD can causes persistent, excessive, and recurrent distress…

This essay will discuss the controversial topic of; the nature, nurture debate. It will do so by examining twin and adoption studies. Through compiling results from various studies conducted by researchers and academics, it will demonstrate inconsistencies, which in turn conclude that human mental processes, and behavior cannot be determined by one specific factor. The nature, nurture debate is a widely regarded topic of inquiry, which aims to define the prevalent force behind an individual’s…

Throughout the book Grit by Angela Duckworth, there were many claims that were made. Duckworth claims that Grit, talent, and other traits that are similar are affected by the genes of a person (82). Duckworth cites Robert Plomin, an american geneticist who is known for his work in twin and behavior genetics. Plomin is a credible source due to his immense research in behavior genetics whereas grit is a behavior. Duckworth used his study where researchers in london gave the Grit Scale which…
