Human behavior is influenced both by the genes that we inherit and the environment in which we live. Some researchers are attempting to locate specific genes or groups of genes, associated with behavioral traits and to understand the complex relationship between genes and the environment. This is called research in behavioral genetics. In contrast to research into the genetic basis of diseases and disorders, researchers in behavioral genetics investigate aspects of our personalities such as intelligence, sexual orientation, susceptibility to aggression and other antisocial conduct, and tendencies towards extraversion and novelty-seeking.

Research in the field of behavioral genetics aims to find out how genes influence our behavior. Researchers are trying to identify particular genes, or groups of genes, that are associated with behavioral traits, and investigating the role of environmental factors.

There are several reasons why it is so difficult to find which genes have an effect on behavioral traits: more than one gene may contribute to a trait, with many genes each having a small effect; a gene may affect more than one trait (for example in mice, memory and sensitivity to pain have been found to be linked); the action of a gene depends on the presence of other genes; environmental factors may contribute to a trait; genes and the environment interact together in different ways; and genes do not have a continuous effect throughout our bodies or for all of our lives.
It is unlikely that variation in just one gene contributes to a behavioral trait. The term a ‘gene for X’ is very misleading and does not convey the complexity of genetic factors. Nor should we overestimate the predictive power of genes. The effects of genes are not inevitable.
Genes, like environmental factors, probably just make a behavior…...

The Link: Genetics and Criminal Behavior

...The Link: Genetics and Criminal Behavior Carla Davis AIU Online An ongoing debate that genetics can be linked to criminal behavior has been ongoing. Researchers are working hard to link criminal behavior and genetics. This study tries to find supporting evidence that a criminal can inherit the notion to commit criminal activity through inheritance. On side believes that criminal activity is caused through inheritance while others agree that genetics has absolutely nothing to do with committing crimes and it’s a person choice when committing a crime or partaking in criminal activities. Included in these studies are adopted studies, twin studies, and testosterone studies. These studying link criminal activities with genetics and give supporting evidence that criminal activities are not inherited. The Link: Genetics and Criminal Behavior Research currently suggests that the genetic characteristics of anger and illegal behavior involve several different factors depending on multiple genes. Although no researcher has been able to put a finger on any genetic factor that could be applied to the concept genes play a part in the influence of aggressive and criminal behavior, many studies have been done to include twin studies and adoption. Twin studies, adoption studies, and testosterone studies are the leading studies that link genetics and criminal behavior.

Human Behavior

...Human behavior refers to the range of behaviors exhibited by humans and which are influenced by culture, attitudes, emotions, values, ethics, authority, rapport, hypnosis, persuasion, coercion and/or genetics. The behavior of people (and other organisms or even mechanisms) falls within a range with some behavior being common, some unusual, some acceptable, and some outside acceptable limits. In sociology, behavior in general is considered as having no meaning, being not directed at other people, and thus is the most basic human action. Behavior in this general sense should not be mistaken with social behavior, which is a more advanced action, as social behavior is behavior specifically directed at other people. The acceptability of behavior is evaluated relative to social norms and regulated by various means of social control. The behavior of humans is studied by the academic disciplines of psychiatry, psychology, social work, sociology, economics, and anthropology. Human behaviour is experienced throughout an individual’s entire lifetime. It includes the way they act based on different factors such as genetics, social norms, core faith, and attitude. Behaviour is impacted by certain traits each individual has. The traits vary from person to person and can produce different actions or behaviour from each person. Social norms also impact behaviour. Humans are expected to follow certain rules in society, which conditions the way people behave. There are certain behaviours......

Spector W e used quantitative genetics techniques to compare the entrepreneurial activity of 870 pairs of monozygotic (MZ) and 857 pairs of same-sex dizygotic (DZ) twins from the United Kingdom. We ran model-fitting analyses to estimate the genetic, shared environmental and nonshared environmental effects on the propensity of people to become entrepreneurs. We found relatively high heritabilities for entrepreneurship across different operationalizations of the phenomenon, with little effect of family environment and upbringing.

Human Genetic Engineering

...Human Genetic Engineering Imagine being able to design your own baby before it is even born, or prevent your unborn child from a dreadful disease, or make your baby a genius or an athlete. Scientists could be opening Pandora’s Box with the potential development of human genetic engineering. Genetic engineering is the process by which genes are added or transferred to alter the genetic code of an organism (“What is Genetic Modification”). Since the completion of the Human Genome Project in 2006, genetic engineering has developed rapidly and it seems as though a new discovery or breakthrough is announced every day. Many of the discoveries as well as future prospects have presented numerous challenges and concerns, and continue to be an ethical debate. Human genetic engineering will lead to unfavorable consequences that defy nature, lead to less diversity, and threaten our safety. Scientists are messing with nature in the process of human genetic engineering. There is a delicate balance in nature that should not be tampered with because of the unforeseen effects it could cause. With advancements in genetic engineering and new technologies, scientists are racing to uncover some profound new discovery by experimenting with our genes in a Petri dish. Manipulations to our genes are unnatural and unpredictable. It was just announced this year that the first human ear was grown from animal cells on the back of a rat (Briggs). While this major breakthrough has enormous potential......

Human Behavior

...Human Behavior Keisha Blue BEH/225 January 17, 2014 Karen Yarber Psychology has been around for some thousands of years which started from an independent experimental field of study. Psychology is when you study the human mind, brain and its functions. It is research to understand and explain how we think, act and feel. A big part of psychology is devoted to diagnosis and treatment of mental health issues. Science is the study structure and behavior of the physical and natural world. This is observed by physical evidence as the basis of that understanding. Psychology investigates an enormous range of perspectives. These perspectives underpinned a shared set of assumptions of what people are like. It is also detailed biological studies of the brain. Just like science, psychology focuses on issues and seeks cause and effects. Psychology evolved into science with two existing sciences: philosophy and physiology. Psychology is considered a science because it uses the scientific method. Psychology evolved into science due to the study of human behavior. The mind is source of ideas and thoughts which correlates from the brain. Psychology asks and answers the fundamental question. We identify them as major perspectives. Major perspectives are assumptions that underlie the research. There are many different ways of thinking about human behavior. There are so many different psychology perspectives. Each one has its own strengths and weaknesses, and brings different......

Human Behavior

...Many people overlook the significance of the biological influence on human behavior. They fail to realize what a big impact our biology as humans have on characteristics, views and behavior. Mutations in our biology and neurological systems are the cause of many of the psychological disorders that people suffer today. Our environment as well as the way we think and feel influence our everyday behaviors. These thoughts and feelings are processed by neurons in the brain and nervous system. Neurotransmitters in our brain and nervous system control all of our functions. When these neurotransmitters don’t function properly, such serotonin which controls sleeping, eating, mood, pain and depression, psychological disorders may arise. Molecular genetics seeks to identify specific genes that are associated with behavior and psychological disorders (Feldman, 2009). Research in molecular genetics has helped to identify genetic markers that are linked to many psychological disorders such as schizophrenia and depression. Research into this field may help develop earlier detection and treatment for these disorders and may also lead to effective gene therapy that can be used to potentially treat these same diseases. Aside from psychological disorders that can be genetically identifiable, physical characteristics that result from our biology and genetics can also affect us psychologically. Although environment also plays a role, physical characteristics such as weight, tone...

Genetics, Brain Structure, and Behavior Presentation Evaluation

...Genetics, Brain Structure, and Behavior Presentation Evaluation Joshua Osman PSY/340 12/16/2013 Rebecca Wilson Schizophrenia is a complicated chronic condition of the brain which causes a person to interpret reality abnormally. In the presentation “Schizophrenia”, Team B dives into the depths of the disease, thoroughly defining and explaining causes and possible genetic onset, which areas of the brain are damaged or interrupted, and how the disorder can affect day to day life of patients. Cures and treatment options are discussed in detail including therapies, future treatment, and preventative methods. This paper will review the information offered by Team B, discuss the overall quality of the information, and assess the level of organization applied. Schizophrenia is a chronic brain disorder that not only affects a person's ability to function cognitively, but also their ability to see reality as it actually is. Brain disorders have the potential to impair any number of human functions and schizophrenia is no different. A breakdown of connections in the brain is a significant aspect of this mental disorder which leads to a lack of emotional stability, thought, and ultimately perception. A mental disorder such as schizophrenia is often crippling and disabling to those who are afflicted. Causes of schizophrenia have yet to be pinpointed, but it is believed to be caused by an overstimulation of dopamine, a......

Genetic Testing and the Human Gmo

...Genetic Testing and the Human GMO The controversies surrounding genetic testing, patenting and the modification of genes both as used in disease treatment and genetic enhancement are on the verge of becoming larger realities. I Intro The initial draft of the Human Genome project is now completed, giving access to the DNA sequences of a human. But it is not the genetic information that is shared that has come under the greatest degree of interest. Rather, the estimated .001% of variance in the genetic code is the subject of recent and expanding controversy; it is our difference not similarities that are most subject to controversy. One such controversy involves the genetic screening of potential employees, to spot potential problematic areas in their genetic make up. Similarly insurance companies may screen clients before deciding what category of clientele to put them in based on genetic risk factors. But the greatest controversies come with the fact that our genetic make up is alterable. There is substantial research being done on how human diseases can be treated using genetic procedures to replace faulty genes, but who stands to profit from this and what are the potential risks? Furthermore, can a treatment based on human genetic information (which is shared by all) be subject to the same patent laws as are other commonly used medicinal tools and methods? And perhaps the most controversial is the prospect of enhancing humans using genetically fostered......

Human Behaviors

...Explanation of Human Behavior Tommy Evans BEH/225 July 17, 2015 How did psychology evolved into a science? Wilhelm Wundt is given credit establishing the first dedicated psychological laboratory back in the 1800s. Wundt wanted to know when it was that we experienced sensations, images and feelings so he set up a lab to observe and measure reactions to different kinds of stimuli. Wundt would introduce different lights, sounds, objects and then look inward to observe carefully his thoughts, feelings, and listen to his body’s senses. While Wundt used this inward looking method even he thought it could be somewhat unreliable so he implemented a scientific method to help keep observations as accurate as possible. To do this thought Wundt has to limit his study to processes that could be observed and measured both internally and externally at the same time. What are some psychological perspectives that explain human behavior? I like humanistic because I agree what humans naturally want to grow and develop. Humans want to be in control of their lives and how they live. Humanistic perspective says that we as humans have free will to make choices that help us reach our full potential. It is our free will and the ability to make the choices that govern our lives that separates us from everything else and makes us uniquely human. Cross-culture is another interesting one. By comparing how different cultures have different behaviors we can see how we are influenced by the......

...effect in other situations [1]. Mehta and Zhu (2009) have published studies that they claim clarify how red and blue differently affect performance on detail-oriented versus creative tasks with strong implications for test preparation and testing formats [2]. According to Sinclair (1998), students taking exams on blue and red paper performed more effectively on blue, especially for complex questions [3]. Whitfield and Wiltshire, in their critical review of the field, discounted the work done before 1950 because it didn’t consider even the three basic components of color (hue, value, and chrome). They also identified flaws in most subsequent research: inconsistencies in the terminology used by respondents to express preferences; lack of attention to surround color (as well as sample color); disregard of the effects of illumination; lack of discussion of size, shape, texture, and complexity of the objects used to present sample colors; and the lack of control for how the very nature of the sample objects might affect a subject’s response to the color of that object. With all these issues, it is not surprising that the field of color psychology has reported a mass of often conflicting results [4]. In the study entitled “Paper Color May Have an Effect on Student Performance” (2009) by David R. Fordham, Professor, David C. Hayes, Assistant Professor of James Madison University stated that, students with white and yellow colored paper performed significantly better than......

Genetics, Brain Structure, and Behavior Evaluation; Autism

...Genetics, Brain Structure, and Behavior Evaluation Over the years autism has been measured a mental illness, a personality disorder, an emotional disturbance, a communication disorder, a developmental disability a mental handicap, as well as, more recently, an information processing problem (Williams, 2006). Autism carries on to be classified as a all-encompassing developmental disorder, a term which mentions children and adults who have severe enduring difficulties in social plus communication skills beyond those accounted for by general developmental delay. Increasingly children are being diagnosed with an autistic spectrum disorder. It is significant that teachers are aware of the features of the disorder and have an understanding of its implications for learning, as well as being able to identify the disorder in its early stages so that appropriate help may be given. Autism is a complex disorder that may not be due to a single cause. It may be that a variety of influences affect neurological development at an early stage (Humphreys and Ramm, 2003). The factors that have been implicated are outlined below. Methodical research has failed to support any more than a small role for the social environment in the development of autism. The conviction that faulty parenting or family factors are implicated has now been discredited, even though raised anxiety levels within the family can lessen children's ability to cope. It is thought that a basic cognitive deficit to do with......

... Positive characteristics of Human Behavior in Organization Interdisciplinary field of study Although it draws most heavily from the psychological and sociological sciences, it also looks to other scientific fields of study for insights. One of the main reasons for this interdisciplinary approach is because the field of organizational behavior involves multiple levels of analysis, which are necessary to understand behavior within organizations because people do not act in isolation. That is, workers influence their environment and are also influenced by their environment. Table 1.1.
