If there is a biological basis
to violence and aggression –
then how would a biosocial theorist
explain white collar crime?
If there are biological explanations for street crimes then by implication biological theory says that member of groups are biologically different, flawed or inferior. The is also a lack of adequate empirical testing.
Rather than suggest that there are born criminals and non-criminals, proponents maintain that some people carry the potential to be violent or antisocial and that environmental conditions can sometimes trigger antisocial responses.Evaluation of Biosocial Trait Theory
The development of the unconscious personality early in childhood influences behavior for the rest of a person’s life. Criminals have weak egos and damaged personalities i.e., anger, sexuality, tendencies. Created by Sigmund Freud.
Explains the onset of crime and why crime and drug abuse cut across class lines.
What type of mood and/or behavioral disorders may affect offenders?Psychological Theory:Psychodynamic Perspective
A great deal of early research efforts found that many offenders who engage in serious, violent crimes
suffer from some sort of mental disturbance.
However, empirical evidence has contradicted this.
Research shows that upon release, prisoners who had prior histories of hospitalization for mental disorders were less likely to be rearrested than those who had never been hospitalized.
Mentally disordered inmates who do recidivate upon release appear to do so for the same reasons as the mentally sound.
People commit crime when they model their behavior after others they see being rewarded for the same acts. Behavior is reinforced by rewards and extinguished by punishment, i.e., learning processes.
Explains the role of significant others in the crime process. Shows how family life and media can influence crime and violence.
What is social learning theory?
Psychological Theory:Behavioral Perspective
Individual reasoning processes influence behavior. Reasoning is influenced by the way people perceive their environment and by their moral and intellectual development, i.e., thinking, memory, ethical values.
Shows why criminal behavior patterns change over time as people mature and develop their moral reasoning. May explain the aging-out process.
Explain the relationship of cognitive processes, perceptions, and chronic offending.Psychological Theory:Cognitive Theory
Personality can be defined as the reasonably stable patterns of behavior, including thoughts and emotions that distinguish one person from another. Personality reflects a characteristic way of adapting to life’s demands and problems.
What is the difference between
nature theory and nurture theory?
Do you think IQ and crime are linked?
If so, why are there more male than female criminals? or,
Why does “aging out” occur?
