The American Psychology–Law Society (AP–LS) is an academic society for legal and forensic psychologists, as well as general psychologists who are interested in the application of psychology to the law. AP–LS serves as Division 41 of the American Psychological Association and publishes the academic journal Law and Human Behavior.

The American Psychology–Law Society has three main goals, which are to advance the contributions of psychology to the understanding of law and legal institutions through basic and applied research, to promote the education of psychologists in matters of law and the education of legal personnel in matters of psychology, and to inform the psychological and legal communities and the general public of current research, educational and service activities in the field of psychology and law. The AP-LS publishes the journal Law and Human Behavior and a newsletter entitled AP-LS News.^[1]

The American Psychology–Law Society (AP-LS) was developed at a San Francisco meeting in September 1968, by founders Eric Dreikurs and Jay Ziskin. The society was created for forensic and clinical psychologists. The first newsletter was published in October 1968. The original constitution was published later that year, and outlined the reasons for creating the society. These were to promote the study of law, influence legislation and policy, and to promote psychology in legal processes. A year after the San Francisco meeting, the AP-LS had 101 members. Most of the members were clinical psychologists, and nine of these original members were women. This group had a stronger focus on psychology, as opposed to the Law and Society Association, which has similar goals, but a broader focus.^[2]

There was a controversy in 1971, when the founder, Jay Ziskin, wrote a book which stated that psychological evidence often did not meet reasonable criteria and should not be used in court of law. This statement sprouted debate in the society and caused the society's popularity to decline for a while. After this, June Louin Tapp became president of the society.^[3]

In 1976, Bruce Sales became the society's president, and helped refocus the society on the field of psychology and law. Sales had the goal to have the American Psychology–Law Society be the driving force behind the group. Sales, along with Ronald Roesch, helped the group publish many books, including Psychology in the Legal Process, Perspectives in Law and Psychology, and the journal Law and Human Behavior.^[2]

In the 1980s, Florence Kaslow asked the group to help develop a certification for forensic psychologists, but the group was not interested. This led Kaslow to create the American Board of Forensic Psychology, which helped keep the American Psychology–Law Society and forensic psychology separated. In the 1980s Division 41 of the APA began to discuss law and psychology, and began covering many similar policies of the AP-LS. Therefore, in 1983, Division 41 and AP-LS merged, under the agreement that Law and Human Behavior would be the journal for the group, and that the biennial meetings would continue to be held. The "new AP-LS" allowed for previous presidents to have a second term in the society, including Bruce Sales, who was the first president of the merged society.^[4]

In 1991, the Committee on Ethical Guidelines for Forensic Psychologists began working to establish rules for forensic psychologists to follow in the court room. In 1992, the committee released "Specialty Guidelines" for forensic psychologists, on top of the Code of Conduct that they already were required to follow.^[2] Additionally in the 1990s, the society also established the Committee on Careers and Education, to help students find training programs to become psychologists in the legal system. In 1995, they held a conference to discuss education at undergraduate and post doctorate levels, how to offer legal psychology courses in the curriculum, and how to offer students experiences.^[4] The AP-LS also provides grants and funding for students who are interested in attending school for law-related psychology.^[1]

The Specialty Guidelines for Forensic Psychologists were first published in 1991. They are guidelines for forensic psychologists to encourage professional, quality, and systematic work in the law system and to those who the forensic psychologists serve. These are the only sets of APA-approved guidelines for a specific area of practice. The guidelines cover 11 points – responsibilities, competence, diligence, relationship, fees, informed consent notification and assent, conflicts in practice, privacy confidentiality and privilege, methods and procedures, assessment, and professional and other public communications.

After an extensive revision process, the Specialty Guidelines for Forensic Psychology were updated in October 2012.^[5][6]

The AP-LS is composed of APA members, graduate and undergraduate students, and people in related fields to join the society. The members primarily have an interest in psychology and law issues. Many members are also members of the American Psychological Association, though it is not a requirement. Members gain access to the publications of Law and Human Behavior and the American Psychology-Law newsletter.^[1]

The AP-LS offers many grants and aid for undergraduates, graduates, early careers professionals, and research. In addition to grants, many awards are handed out yearly.^[1]
