242 Test 3 Key Terms Flashcards
Criminal profiling:
An investigative technique for
identifying the major personality
and behavioural characteristics of
an individual based upon an
analysis of the crimes he or she has
committed
criminal profiling is now used for a number of purposes,
including the following
- To help set traps to flush out an offender
- To determine whether a threatening note should be taken seriously
- To give advice on how best to interrogate a suspect
- To tell prosecutors how to break down defendants in cross-examination
the RCMP prefers to use the term — , which suggests a broader focus than profiling
criminal investigative analysis
ViCLAS:
The Violent Crime Linkage
Analysis System, which was
developed by the RCMP to collect
and analyze information on serious
crimes from across Canada
Linkage blindness:
An inability
on the part of the police to link
geographically dispersed serial
crimes committed by the same
offender because of a lack of
information sharing among police
agencies
Two profiling methods are often talked about:
the deductive profiling method and the inductive profiling method
Deductive criminal profiling:
Profiling the background
characteristics of an unknown
offender based on evidence left at
the crime scenes by that particular
offender
Inductive criminal profiling:
Profiling the background
characteristics of an unknown
offender based on what we know
about other solved cases
Organized-disorganized model:
A profiling model used by
the FBI that assumes the crime
scenes and backgrounds of serial
offenders can be categorized as
organized or disorganized
organized characteristics reflect a methodical individual, while disorganized characteristics reflect a disturbed individual, who is usually suffering from some form of psychopathology
criticisms of profiling
- Many forms of profiling appear to be based on a theoretical model of personality
that lacks strong empirical support.
- The core psychological assumptions underlying profiling currently lack strong
empirical support.
- Many profiles contain information that is so vague and ambiguous they can
potentially fit many suspects.
- Professional profilers may be no better than untrained individuals at constructing
accurate profiles.
Classic trait model:
A model of
personality that assumes the
primary determinants of behaviour
are stable, internal traits
FBI’s organized-disorganized approach, rely on a classic trait model of personality that was popular in psychology before the 1970s. In this model, the primary determinants of behaviour are stable, internal traits
Two assumptions in particular have been tested by researchers:
(1) that offenders behave in a stable fashion across the crimes they commit and (2) that reliable relationships exist between the way in which offenders commit their crimes and their background characteristics
Geographic profiling:
An investigative technique that uses
crime scene locations to predict the
most likely area where an offender
resides
most often in cases involving very violent crimes, though it has also been used in cases of serial robbery,
arson, and burglary
Geographic profiling systems:
Computer systems that use
mathematical models of offender
spatial behaviour to make
predictions about where unknown
serial offenders are likely to reside
Internalizing problems:
Emotional difficulties such as
anxiety, depression, and obsessions
experienced by a youth
Externalizing problems:
Behavioural difficulties such as
delinquency, fighting, bullying,
lying, or destructive behaviour
experienced by a youth
Attention deficit/hyperactivitydisorder:
A disorder in a youth
characterized by a persistent pattern
of inattention and hyperactivity or
impulsivity
Oppositional defiant disorder:
A disorder in a youth characterized
by a persistent pattern of negativistic,
hostile, and defiant behaviours
Conduct disorder:
A disorder
characterized by a persistent pattern
of behaviour in which a youth
violates the rights of others or ageappropriate
societal norms or rules
Mental health professionals are expected to consider the likelihood that their patients will act in a violent manner and to intervene to prevent such behaviour.
This responsibility is called
duty to warn .
To be declared a — , a person must pose a substantial risk for violently reoffending
long-term offender
True positive:
A correct
prediction that occurs when a
person who is predicted to engage
in some type of behaviour
(e.g., a violent act) does so
True negative:
A correct
prediction that occurs when a
person who is predicted not to
engage in some type of behaviour
(e.g., a violent act) does not
