Each of these look at the human mind and find different explanations for how it works and how people behave. Some of the key psychological perspectives are;
Behaviourist
Social Learning
Psychodynamic
Humanistic
Cognitive
Biological

Behaviourist Theory
The behaviourist theory of psychology was founded by J.B Watson in 1959, and is based around the idea that individuals act in a certain manner because they’ve learnt to behave that way due to a factor in their environment that stimulates a positive or a negative response from them.

This is because certain disorders, such as Huntington’s disease or Cystic Fibrosis, are caused by the alleles in a persons’ genetic composition. As they’re caused by genetics, these disorders – and others like them – will occur regardless of the environment in which an individual is placed, and these disorders can have a large impact upon behaviour.

For instance, Huntington’s disease usually begins displaying symptoms after 30 years of age, and changes in behaviour such as hallucinations, confusion, memory loss and personality changes occur. This may cause depression, isolation and decreased ability within individuals which is caused by the genetics of the disease rather than the environment.

Furthermore, there are other disorders for which there can be a genetic predisposition; meaning, whilst a person’s genes don’t cause a person to have the disorder, it causes them to be more likely to develop it – such as in some cases of depression.
Twin studies are often used to determine how greatly genetics can contribute to a person’s character. This is because identical twins share exactly the same DNA, so the use of twins can investigate what may have been caused by genes as logically, if something is caused by genes then both the twins will exhibit

    It is without question that DNA is the building blocks of any human being, recent studies have found that your genetic makup has a significant impact on how a person responds to stress, which can make certain people susceptible to mental illness, most notably depression. (Srijan Sen, 2011) It is believed that your DNA allows for a range of possible characteristics and tendencies that is then determined by your environment and daily activities. This last point of course leads to the heart of the controversy between genetic predisposition and environmental triggers, and which is more prominent. A study released by Livesley in 1993 is a perfect example of the attempt to link genetic predisposition strongly to mental illness and found that Narcissistic Personality Disorder had a 64% heritability rate. This study however was widely criticized as to having no consistency with its chosen participants and also failed to mention if any of the participants or their parents had a personality disorder. Due to these external variables, it was believed that the margin of error was too significant for the studies findings to hold any real merit in presenting a strong link between genetic predisposition and NPD in particular.…

    The fourth factor is genes. Important new genetic research has highlighted the possibility that some people may be genetically at risk of development a mental disorder but so far the strong evidence relates to conditions such as schizophrenia and bipolar depression. It has been shown that a son or daughter of someone with schizophrenia have a 10% chance of receiving it them self.…

    The genetic makeup of hereditary can impact the human behavior and heredity is already present in your genes. May be you will show such behavior because of hereditary once in a day but it is always there. However, the behavior can change which creates the contrast from heredity and such cases arise in the case of the changes in the hormonal balance in the body because of diet changes.…

    Genetic disorders are present from birth, but they may not be visibly seen until a later age. Some mutations could be heritable, or from your parents genes. Some forms of cancer can be inherited form a parent. Although, in most cases, these mutations are new changes to the DNA. “All humans have the same basic set of genes”. This means that everyone has the probability that they could get a genetic disorder. The thing that makes us different is the genetic sequence.…

    Genetic factors can cause individuals to be predisposed to develop an array of mental aliments. A shocking 40-60% of addiction vulnerable people can be linked to genetic factors (NIDA, 2008). The genetic factors arise from the nature vs nurture phenomenon, which looks at genetics vs environment and their interaction between both.…

    Genetics play a major role in whether teens have eating disorders. Researchers discovered that eating disorders have a proclivity to run in families. Dieticians and researchers used genetic mapping to discover that chromosomes are linked to both bulimia and anorexia. Children are possibly born with illnesses, such as bulimia and anorexia because it is prevalent or common in their families. Some children are born with abnormal levels of chemicals to regulate appetite, sleep, and stress. For example, genetics causes certain individuals to have too much serotonin, which is the main cause of anorexia. Genetics is not an external stimuli, so some teens can be simply be born with eating disorders.…

    This review focuses on the possible factors that play a role on the development of psychological disorders such as genetic, biological and environmental influences whereby genetic influence involve the imbalance of neurotransmitters that prevent individual’s brain from functioning efficiently as compared to healthy individuals whereas biological influences such as cognitive deficits that impaired partial brain functions of individuals while environmental influence does not directly relates to functional system of brain that involve facing changes in life such as loss of individuals’ health or close relatives which was unexpected would usually trigger the development of psychological disorder such as depression yet depression is likely to be developed differently by different people. Hence, suitable treatment for each individual will usually depend on the outcome of the evaluation that depends on the severity of condition to maintain a pro-longed stability of individual’s condition.…

    Twin studies are, “comparisons of identical (monozygotic) twins to fraternal or nonidentical (dizygotic) twins.” These studies are mainly to contribute to hereditary effects and also estimate heritability. Scientists and researchers look toward twin studies to debate the nature versus nurture on childhood. For many years scientists have tried to study twins to see if genetics and/or environment influence individuals. Sir Francis Galton (one of the first scientists to conduct twin studies) studied influential genetics are on intelligence, more than a century ago. Galton also suggested that children get their intelligence from parents. “Identical twins have the same genetic construction. So, by studying identical twins who were brought up in different environments, “scientists can see the impact of genes on development.” For fraternal twins, scientists study the impact of outside environment on the children’s personalities (Bryner, 2006).…

    Twin studies play a very important role into determining whether or not personality is genetically influenced. Identical twins are siblings who share 100 percent of genes with each other. They are more or less the best participants to prove whether or not personality is genetically influenced. Fraternal twins share 50 percent of genes with each other. They are excellent participants to compare with identical twins. Twin studies generally rely on findings of identical and fraternal twins; if identical twins have more similar behaviour than non-identical twins then this provides evidence for genetics influence on personality.…

    The study of nature and nurture in the development of behavioral traits begun around 1865 from Francis Galton, and has grown significantly since then. Genetic research has overall shown genetic influence in psychological areas such as mental illness, cognitive disabilities, personality, drug use and abuse. Areas such as self-esteem, interests, attitudes, and school achievements have showed stronger genetic influence. A recent poll found that more than 90% of parents and teachers reported genetics as being as important as the environment for mental illness, personality, learning difficulties, and intelligence. Genetics and environment influence individuals’ characteristics and each account for about half of the variance.…

    Psychology, according to Gross (2009:4) is literally “…the study of the mind”, derived from the Greek words ‘psyche’ which translates as mind, soul or spirit and ‘logos’ meaning knowledge or study. However, this definition is far too simplistic and throughout history many well known theorists have debated its true meaning.…
