- Legal psychology
Legal psychology involves
empirical, psychological research of the law, legal institutions, and people who come into contact with the law. Legal psychologists typically take basic social and cognitive theories and principles and apply them to issues in the legal system such as eyewitness memory, jury decision-making, investigations, and interviewing. The term "legal psychology" has only recently come into usage, primarily as a way to differentiate the experimental focus of legal psychology from the clinically-oriented forensic psychology. [ [http://www.apa.org/science/aps_for.html Forensic and Legal Psychology] , American Psychological Association]
Together, legal psychology and forensic psychology form the field more generally recognized as "psychology and law". Following earlier efforts by psychologists to address legal issues, psychology and law became a field of study in the 1960s as part of an effort to enhance justice, though that originating concern has lessened over time.

Further, its mandate is to inform the psychological and legal communities and the public at large of current research, educational, and service in the area of psychology and law. [cite web

Areas of research
Generally speaking, any research that combines psychological principles with legal applications or contexts could be considered legal psychology (although research involving clinical psychology, e.g., mental illness, competency, insanity defense, offender profiling, etc., is typically categorized as
forensic psychology, and not legal psychology). For a time, legal psychology researchers were primarily focused on issues related to eyewitness testimonyand jury decision-making; so much so, that the editor of Law and Human Behavior, the premier legal psychology journal, implored researchers to expand the scope of their research and move on to other areas. [ Michael J. Saks(1986). The Law Does Not Live on Eyewitness Testimony Alone. " Law and Human Behavior, 10," 279-280.]
There are several legal psychology journals, including "
Law and Human Behavior", "Psychology, Public Policy and Law", "Psychology, Crime, and Law", and "Journal of Psychiatry, Psychology and Law" that focus on general topics of criminology, and the criminal justice system. In addition, research by legal psychologists is regularly published in more general journals that cover both basic and applied research areas.
Training and education
Legal psychologists typically hold a
Ph.D.in some area of psychology (e.g., clinical psychology, social psychology, cognitive psychology, etc.), and apply their knowledge of that field to the law. Although formal legal training (such as a J.D.or Master of Legal Studies degree) can be beneficial, most legal psychologists hold only the Ph.D. In fact, some argueFact|date=September 2007 that specialized legal training dilutes the psychological empiricism of the researcher. For instance, to understand how eyewitness memory "works," a psychologist should be concerned with memory processes as a whole, instead of only the aspects relevant to the law (e.g., lineups, accuracy of testimony).
A growing number of universities offer specialized training in legal psychology as either a standalone
Ph.D.program or a joint J.D./ Ph.D. program. A list of American universities that offer graduate training in legal psychology can be found [http://www.unl.edu/ap-ls/student/graduate_programs.html here] on the website of the [http://www.ap-ls.org/ American Psychology-Law Society] .
Roles of a legal psychologist
Academics and research
Many legal psychologists work as
professorsin university psychology departments, criminal justice departments or law schools. Like other professors, legal psychologists generally conduct and publish empirical research, teach various classes, and mentor graduate and undergraduate students. Many legal psychologists also conduct research in a more general area of psychology (e.g., social, clinical, cognitive) with only a tangential legal focus. Those legal psychologists who work in law schools almost always hold a J.D.in addition to a Ph.D.
Psychologists specifically trained in legal issues, as well as those with no formal training, are often called by legal parties to testify as expert witnesses. In criminal trials, an expert witness may be called to testify about eyewitness memory,
mistaken identity, competence to stand trial, the propensity of a death-qualified juryto also be "pro-guilt," etc. Psychologists who focus on clinical issues often testify specifically about a defendant's competence, intelligence, etc. More general testimony about perceptual issues (e.g., adequacy of police sirens) may also come up in trial.
Experts, particularly psychology experts, are often accused of being "hired guns" or "stating the obvious."Fact|date=March 2008 Eyewitness memory experts, such as
Elizabeth Loftus, are often discounted by judges and lawyers with no empirical training because their research utilizes undergraduate students and "unrealistic" scenarios.Fact|date=March 2008 If both sides have psychological witnesses, jurors may have the daunting task of assessing difficult scientific information.
Policy making and legislative guidance
Psychologists employed at public policy centers may attempt to influence legislative policy or may be called upon by state (or national) lawmakers to address some policy issue through empirical research. A psychologist working in public policy might suggest laws or help to evaluate a new legal practice (e.g., eyewitness lineups). [Examples of legal psychologists in these positions can be found at the
American Bar Foundation( [http://www.abf-sociolegal.org/ Website] ) and Federal Judicial Center( [http://www.fjc.gov Website] ), among others.]
Legal psychologists may hold advisory roles in court systems. They may advise legal decision makers, particularly judges, on psychological findings pertaining to issues in a case. The psychologist who acts as a court adviser provides similar input to one acting as an expert witness, but acts out of the domain of an
adversarial system. [See, e.g., [http://www.aaas.org/spp/case/case.htm Court Appointed Scientific Expert Program] , American Association for the Advancement of Science]
Psychologists can provide an
amicus briefto the court. The American Psychological Associationhas provided briefs concerning mental illness, retardation and other factors. The amicus brief usually contains an opinion backed by scientific citations and statistics. The impact of an amicus brief by a psychological association is questionable. For instance, Justice Powell [ [http://www.law.cornell.edu/supct/html/historics/USSC_CR_0435_0223_ZC2.html Ballew v. Georgia ] ] once called a reliance on statistics "numerology" and discounted results of several empirical studies. Judges who have no formal scientific training also may critique experimental methods, and some feel that judges only cite an amicus brief when the brief supports the judge's predisposition.
Some legal psychologists act as
trial consultants. No special training nor certification is needed to be a trial consultant, though an advanced degree is generally welcomed by those who would hire the trial consultant. The American Society of Trial Consultants does have a code of ethics for members, but there are no legally binding ethical rules for consultants. [An overview of the trial consulting process is provided by the American Society of Trial Consultants, [http://www.astcweb.org/ ASTC Website] ]
Some psychologists who work in academics are hired as trial consultants when their expertise can be useful to a particular case. Other psychologist/consultants work for or with established trial consultant firms. The practice of law firms hiring "in-house" trial consultants is becoming more popular, but these consultants usually can also be used by the firms as practicing attorneys.
Trial consultants perform a variety of services for lawyers, such as picking jurors (usually relying on in-house or published statistical studies) or performing "mock trials" with focus groups. Trial consultants work on all stages of a case from helping to organize testimony, preparing witnesses to testify, picking juries, and even arranging "shadow jurors" to watch the trial unfold and provide input on the trial. There is some debate on whether the work of a trial consultant is protected under attorney-client privilege, especially when the consultant is hired by a party in the case and not by an attorney.
