2.) Professional Practice
-They examine human behaviour in regards to the legal system
‘(Bartol and Bartol)’
Legal Psychology
Legal psychology is the scientific study of the effect of the law on people; and the effect people have on the law. Legal psychology also includes the application of the study and practice of psychology to legal institutions and people who come into contact with the law.
How does psychology interact with the law?
Psychology and the law
Psychology in the law
Psychology of the law
Psychology and the law
-The use of psychology to study the operation of the legal system
-Psychology and law are more equal and cooperative
“the co-equal and conjoint use of psychological principles to analyze and examine the legal system” (Haney, 1980)
-Research offers the potential to reform or change legal practices
Psychology in the law
-The use of psychology within the legal system as it currently operates
-Members of the legal profession call on psychologists to assist with the legal issue(s) at hand (e.g., assess mental state; use psychological techniques in jury selection)
“The legal system dominates and completely dictates the form and application of psychology in law” (Craig Haney, 1980)
-Psychology is subservient to the law
Psychology of the law
- The use of psychology to study the law itself
- Psychology used to study the law itself; i.e., the law becomes “an object of psychological study in itself” (p. 156)
- Least studied area - most work done by anthropologists
Types of Forensic Psychologists
Clinical and Experimental
Services that Forensic Psychologists provide
with victims of crime
with criminal justice personnel (e.g., police; secretaries; correctional staff)
consult with members of the criminal justice system (e.g., lawyers and judges)
with inmates and offenders
conduct research
Describe psychologists deal with correctional systems
Psychologists who work in correctional settings provide clinical and consultation services in four broad areas:
Assessment (also in pretrial and remand centres)
Treatment and intervention
Crisis intervention
Program development, delivery, and evaluation
-Typically devote most of their time assessing and treating inmates and offenders
How does psychology influence the law
Amici briefs (“social framework”) to courts and commissions, Attorneys-General, Ministry of Justice:
- May influence trial outcome and serve as established authority in future cases
- May alter investigative and legal procedures
- May force reviews of previous cases that relied upon demonstrably erroneous evidence
Expert witnesses and Inquiries:
- Provision of testimony on BWS (in R. v. Lavallee, 1988), PTSD, or rape trauma syndrome, etc.
- Provision of psychological assessments on defendant’s competence to stand trial, responsibility (re: mental disorder) etc.
- Eyewitness testimony (e.g., Sophonow Inquiry, 2000)
- Recovered memories
Social science taught in law school
Citation of research in trial judgments
Availability of research in professional journals
Outcomes of specific cases and psychological practice
Methodical focus to Forensic Pysch?
Law:
Use “case method” - focus on specific allegations, individuals, prior similar cases and application to this case
Direction is deduction, from general theory to the specific
Psychology:
Describes the general principles and patterns across aggregated people
Direction is induction - case studies used only as exploratory
Implications:
Law has been much more responsive to the idiographic emphases in psychology, through practitioners who do individual assessments, etc.
Expressions of Confidence
Law seeks “certainty”
Decisions have no middle ground
Guilt – innocence
Acquit – convict
Reasonable doubt or preponderance of evidence, but one position is right
Psychology conclusions in probabilistic terms
It depends!
Trial and experiments similar: set up a “null hypothesis” and look at evidence for its rejection:
Trial - assume innocence until proven guilty
Exp- assume no effect until difference demonstrated
Approach to the truth in this field
Stare Decisis – to stand by decided cases, or precedent, and is doctrinal
New cases create new law and new precedents
Law is constantly changing - by argument rather than data
Goal of science - critically assess if previous findings are reliable and establish new findings that may contradict old
Historical beginnings of forensic psychology
Munsterberg (1908) On the Witness Stand Psychology and the legal system Resistance from legal scholars Pushed psychology into legal arena
What criteria is required for testimony to be admitted in the courts?
Mohan criteria (1994) - (in addition to relevance):
i.Proper role
Not to usurp role of trier of fact - knowledge may be within their common understanding
ii.Probative value outweighs prejudicial value
iii.Reliability of evidence and methodology
iv.Credentials of expert
Decision via voir dire(swearing on the bible)
