1、Forensic Psychology Origin of the term Forensic from the Latin word “forum” public gathering places in the Roman city- states where much of the judicial process took place in the form of debates thus, forensic psychology deals with the intersection of psychology and the legal process Definition The

6、 an understanding of what is happening to them in a courtroom and who cannot participate in their own defense are said to be incompetent to stand trial. Defense attorneys suspect impaired competence in their clients in up to 10 percent of cases. Psychologists have developed tests of cognitive abilit
7、ies important to following legal proceedings, and people who perform poorly on these tests. Insanity Defense Insanity is actually a legal term rather than a psychological or medical term, and it has been defined in various ways. All definitions of insanity reflect the fundamental doctrine that peopl
8、e cannot be held fully responsible for their acts if they were so mentally incapacitated at the time of the acts that they could not conform to the rules of society. Insanity Defense, continued While the lay public often thinks of the insanity defense as a means by which guilty people “get off,” the
9、 insanity defense is used much less often than the public tends to think. Fewer than 1 in 100 defendants in felony cases file insanity pleas, and of these only 26% result in acquittal.

12、 wrong. Irresistible Impulse Rule At the time of the crime the individual was driven by an irresistible impulse to perform the act or had a diminished capacity to resist performing the act. Durham Rule The crime was a product of a mental disease or defect. Insanity Defense Rules ALI Rule At the time
13、 of the crime, as a result of mental disease or defect, the person lacked substantial capacity either to appreciate the criminality (wrongfulness) of the act or to conform his or her conduct to the law.

14、 person was unable to appreciate the wrongfulness of his or her conduct. Guilty but Mentally Ill Defendants convicted are incarcerated for the normal terms designated fro their crimes, with the expectation that they will also receive treatment for their mental illness. Civil Commitment Before 1969,
15、in the U.S., the need for treatment was sufficient cause to hospitalize people against their will. Such involuntary hospitalization is called civil commitment. Since 1969, the need for treatment alone is no longer sufficient legal cause for civil commitment in most states. Criteria for Involuntary C

Involuntary Commitment and Civil Rights People who have been committed to a mental institution often feel that they have given up all their civil rights. But numerous court cas
17、es over the years have established that these people retain most of the civil rights, and have certain additional rights due to their committed status. l Right to Treatment l Right to Refuse Treatment Child Custody Disputes Ninety percent of the time, parents who are divorcing can agree on the custo
18、dy arrangements for their children without taking disputes to court. If parents cannot agree, however, the court must help determine how much authority each parent will have in decisions for the children and how much contact each parent will have with the children. The law requires that custody deci

The psychologist may conduct interviews and also testify in court. Training in Forensic Psychology Few Ph.D. o
20、r Psy.D. programs offer specialty training in clinical-forensic psychology. Most clinical-forensic psychologists are graduates of general clinical psychology programs who developed their specialty later in their training, either on internship, by way of completing a forensic fellowship, or by indepe

Students interested in becoming clinical- forensic psychologists should consider a clinical Ph.D. or Psy.D. program which offers a forensic specialization or enter a clinical doctoral program which houses a faculty member whose research and clinical interests ar

A Note About Criminal Profiling Due to depictions in popular media (e.g., Silence of the Lambs, Profiler, CSI), many students express an interest in and ask questions about c
23、riminal profiling, which may be described as a criminal investigative technique based, in part, on psychological expertise and knowledge. In reality, few law enforcement agencies employ such techniques and there is little call for such professionals. Those interested in such work would probably do b
24、etter to consider a career in law enforcement than clinical-forensic psychology. The Behavioral Sciences Unit of the FBI, does employ a few FBI agents who engage in this activity. The FBI makes a distinction between mental health and law enforcement: FBI agents are law enforcement professionals, not mental health professionals. In order to work as a profiler, or with the FBI in any other role, it is necessary to become an FBI agent.
