Personality theorists have attempted to gauge the effects of personality development on criminal behavior by administering personality tests to groups of criminals and noncriminals. The evidence from these studies is mixed. In some instances, researchers found differences between the two groups on certain dimensions of personality, such as impulsiveness. However, in other instances no differences were found. Studies of mental disorders comparing prisoners and other populations suggest that only a few relatively rare crimes, such as sexual crimes of violence involving extremely deviant acts, can be attributed to mental illness.
Chemical methods of control: The use of pharmacological treatments to try to control crime has been ongoing in two major areas: chemical castration for sex offenders and pharmacological interventions for drug or alcohol addicts. However, addicts can stop the medication and return to use. Sex offenders are closely monitored and there is some evidence that this policy has been efficacious. Sometimes mentally ill people in the criminal justice system been ordered to take medications to treat their mental illness. Other pharmacological interventions to control crime seem plausible and are being investigated, but do not appear to have been widely used.
Personality theories attempt to explain how people acquire predispositions toward certain behavior. These predispositions are sometimes discussed in terms of personality traits, such as impulsiveness and stubbornness, or personality types, such as introvert and extrovert. All other things being equal, people will consistently display behaviors that they are predisposed toward. Accordingly, some social scientists believe that certain predispositions or personality types may be associated with criminal tendencies or activities.
Humanistic psychology theories began to grow in popularity during the 6955s. While earlier theories often focused on abnormal behavior and psychological problems, humanist theories instead emphasized the basic goodness of human beings. Some of the major humanist theorists included Carl Rogers and Abraham Maslow.
Throughout psychology s history , a number of theories have been proposed to explain and predict various aspects of human behavior. Some of these theories have stood the test of time and remain well-accepted today. Others have not held up under close scientific scrutiny and may have been rejected altogether or only partially accepted by researchers today.
Researchers in the field of criminology have endeavoured to obtain a more-accurate picture of the incidence of crimes and the trends and variations from one period and jurisdiction to another. One research method that has been particularly useful is the victim survey, in which the researcher identifies a representative sample of the population and asks individuals to disclose any crime of which.
