Discuss genetic factors in aggressive behaviour - 1029.

Genetic Factors and Criminal Behavior Essay; Genetic Factors and Criminal Behavior Essay. It is very complex and can in some cases cause people to behave criminally. There are genetic factors that can influence a person’s behavior as well as environmental factors.. with treatment being effective only with the reduction of aggression.

The factors that contribute to aggressive behaviors can be divided into biological and psychosocial factors. Biological factors can occur from the brain and its nervous system, through genetics or as a result of bio chemicals which include those that are ingested such as alcohol or the natural body chemicals such as hormones.

The basic difference between men and women lies in their genotype. Most people have 23 pairs of chromosomes and on these chromosomes are our genes. One pair of chromosomes decides whether we are male (XY) or female (XX). Early psychologists investigating aggression believed the genetic cause of aggression could lie in the Y chromosome.

A problem with the explanation of genetic factors of aggression is that it is a biological approach and hence deterministic.Determinism is the view that an individual’s behaviour is controlled by internal or external forced, rather than an individual’s own free will.

Revision notes for the A-level psychology aggression topic updated for the 2016 exam. Print them off for your reference.. animals show aggressive behavior and when its removed, they no longer show aggressive behavior.. Genetic factors do not work in isolation but interact with environmental factors as well. Deterministic: Assumes that.

Conducted a study with 82 MZ and 118 DZ twins. Findings showed from this study that genes were able to account for 40% of individual differences in aggressive behaviour. However environment was found to account for 50% of individual differences in physical aggression and 70% for verbal aggression.

According to a meta-analysis on data from 24 genetically informative studies, up to 50% of the total variance in aggressive behavior is explained by genetic influences. Nature and nurture. Both our genotype and the environmental factors to which we are exposed to throughout life contribute to shaping our brain functions.

With reference to relevant to research studies, to what extent does genetic inheritance influence behaviour?

The genetic explanation for aggression suggests that aggression is an inherited behaviour. Early genetic explanations focused on chromosomal abnormalities. Specifically, in the 1960s, the XYY genotype was believed by many to be correlated with aggression. More recently, research has focused on a defect in the MAOA gene, which is linked to aggression.

Abstract. Behavioral genetics has contributed to the study of psychopathology in three ways: (1) It has provided a theory of the genetic and environmental origins of individual differences in behavioral pathology, (2) devised methods that can disentangle the influence of nature and nurture, and (3) produced data that converge on the conclusion that hereditary influences are important in.

Definitions and Importance. Although interrelated, it is important to differentiate between the concepts of aggression, aggressive behavior, and violence ().Aggressive behavior can be conceptualized as the observable manifestation of aggression, which is defined as any act intended to cause harm, pain, or injury in another (Zirpoli, 2008).It is important to note that although aggressive.

In this article the two authors research the connection between genetic factors and criminal behavior. They look at the causes that make someone act in a criminal way. There are several factors looked at in connection to the cause such as social factors and environmental variables. The social factors being the more examined of the two.
