TRAIT THEORY

DEVELOPMENT OF TRAIT THEORYCrime is a function of internal forces such as chemical,

neurological, genetic, personality, intelligence, or mental traits.Focus on individual and give many reasons of crime.The view that criminal have physical or mental traits (born

criminals) that make them different originated with the Italian physician and criminologist Cesare Lombroso.

In the early 1970s, spurred by the publication of “Sociobiology”, the new synthesis, by Edmund O. Wilson, biological explanation of crime once again emerged.

Trait theories today recognize crime-producing interactions that involve both personal traits and environmental factors.

CNTEMPORARY TRAIT THEORYEach offender considered physically unique. So, there

must be unique explanation for each criminal.Some may have inherited criminal tendenciesOther may be suffering from neurological problems, blood

chemistry disorder, that height there anti social behavior.Bernard Rim-land concur that what may appear to some

as the effect of environment and socialization may be actually linked to genetically determined physical or mental trait.

BIOLOGICAL THEORIES OF

CRIME

BIOLOGICAL THEORIES OF CRIMEFocus on biological human conditions that

control human behavior .Theory tells about :

Biochemical behavior factors that are believed to affect how proper behavior pattern are learned. That we considered the relationship between brain function and crime.

Association between genetic factor and crime. Evolutionary view of crime causation.

BIOLOGICAL THEORIES OF CRIME1- Biochemical conditions and crime

Some biochemical conditions (genetically predetermine and acquired through diet and environment) influence antisocial behavior.

Biochemical makeup and antisocial behavior is indirect: chemical and mineral imbalancement leads to perceptual and intellectual defect and problems, which may eventually generate antisocial behavior.

Researcher discover that blood mercury levels of children diagnosed with ADHD(attention deficit/hyperactivity disordered significantly higher then other population, indicating a clear association between an environmental pollutants and behavior disorder.

BIOLOGICAL THEORIES OF CRIME Diet:

Improper diet can cause chemical and mineral imbalance and can lead to cognitive and learning deficits and problems.

Research shows that undersupply of chemicals(sodium, mercury, potassium, calcium, amino acid, and iron) can lead to depression, hyperactivity, cognitive problems, memory lose or abnormal sexual activity.

People whose diet lack of polyunsaturated fats, minerals, vitamins and too much saturated fats seem to be at higher risk of developing psychological disturbance, such as schizophrenia, that directly related to anti social behavior.

Kids with faulty diet tend to be starved for attention that may led to school failure.

BIOLOGICAL THEORIES OF CRIME Hypoglycemia:

A condition that occurs when glucose (sugar) in blood falls below levels necessary to normal and efficient brain functioning.

Symptoms include irritability, anxiety, depression, crying spells, headaches and confusion.

Hypoglycemia outbursts of antisocial behavior and violence.

BIOLOGICAL THEORIES OF CRIME Hormonal influence

1. Androgen: Male sex hormones. Aggressive behavior, sensation seeking, impulsivity, dominance,

and reduced verbal skills are androgen related male traits. Hormonal change also related to mood and behavior. Adolescence experience more intense mood swings, anxiety, and

restlessness then their elders, explaining in part the high violence rates found among teenage males.

2. Testosterone: High level of testosterone is directly related to aggression in

both male and female.

BIOLOGICAL THEORIES OF CRIMEEnvironmental containment:

Prenatal exposure to PCBs(polychlorinated biphenyls) to lower IQs and attention problem.

Both considered risk factors for serious behavioral and learning problem.

Air pollution create cognitive deficits and change the brain structure of healthy children's, that associated with school failure, educational underachievement and adult criminality.

BIOLOGICAL THEORIES OF CRIME 2- NEUROPHYSIOLOGICAL CONDITIONS AND CRIME

Inherited or acquired neurological and physical abnormalities control behavior throughout life span.

Both violent and criminals and substance abusers have impairment in the prefrontal lobes, thalamus, medial temporal lob, and superior parietal and left angular gyrus area of the brain.

There is suspected link between brain dysfunction and conduct disorder(a pattern of repetitive behavior in which the right of other or social norms violated.

BIOLOGICAL THEORIES OF CRIMEAttention deficit/hyperactivity disorder(ADHD)

Lack of attention Frequently fails to finish projects Dose seem to pay attention Does not sustain interest in play activities Cannot sustain concentration on schoolwork or related tasks

Impulsivity Frequently act without thinking Often call out in class Does not want to wait his or her turn in lines or games Shift from activity to activity Cannot organize task or work Requires constant supervision.

Hyperactivity Constantly run around and climbs on things Shows excessive motor activity while asleep Cannot sit still: is constantly fidgeting Does not remain in his or her seat in class Is constantly on the go like a motor.

BIOLOGICAL THEORIES OF CRIME3- GENETICS AND CRIMEParental deviance:

Anti-social behavior is inheritedThe genetic make-up of parents is passed on to

childrenThe genetic abnormality is linked to variety of

antisocial behavior.Cambridge youth study says number of

delinquent youth have criminal fathers.Number of studies found that parental

criminality and deviance do, in fact, power fully influence delinquent behavior.

BIOLOGICAL THEORIES OF CRIMEAdoption studies:

Several studies indicates that relationship between the behavior of biological parent and their children remain even if they are not in contact.

when both biological and adoptive father are criminal, the children would engage in criminal behavior.

BIOLOGICAL THEORIES OF CRIME

Twin behavior:Studies conducted on twin behavior have detected a

significant relationship between the criminal activities of MZ and a much lower association between those of DZ twins: MZ twin has higher risk of suicidal behavior then DZ twins. The score of MZ twins are more similar than DZ twins on

tests measuring psychological dysfunctions such as conduct disorders, impulsivity and antisocial behavior.

MZ twins are closer than DZ twins in such crime measures as a level of aggression and antisocial behavior.

Both member of MZ twins pairs who suffer child abuse are likely to engage in later antisocial activity more often than DZ pairs.

BIOLOGICAL THEORIES OF CRIME4- EVOLUTIONARY VIEW OF CRIMEThe competition of scarce resources has influenced and

shaped the human species.Behavior patterns are inherited, impulsive behavior

become intergenerational, passed down from parents to children.

Evolutionary concept have been linked in gender differences in violence rate are based loosely on mammalian mating patterns.

To ensure the survival of gene pool, it is beneficial for a male to mate with any female as possible to bear his offspring.

Over the history of human being aggressive males have greatest impact on the gene pool.

PSYCHOLOGICAL THEORIES &CRIME

PSCHOLOGICAL THEORIES OF CRIME1. Psychodynamic model

The development of the unconscious personality early in childhood influences behavior for the rest of person’s life.

criminals have weak egos and damaged personality.

2. Behavioral theories People commit crime when they model their behavior after others

they see being rewarded for the same act. Behavior is reinforced by rewards and extinguished by punishment.

3. Cognitive theory Individual reasoning processes influence behavior. Reasoning is influenced by the way people perceive their

environment.

PSCHOLOGICAL THEORIES OF CRIME1- PSYCHODYNAMIC MODEL OF CRIMESigmund Freud(1856-1939)

Human body has three part structure.1. Id

The primitive part of people mental make up, present at birth, that represent unconscious biological drives for food, sex and other life sustaining necessities.

The id seeks instant gratification with concern for right of others.

2. Ego The part of personality develops in early childhood that helps

control the Id and keep peoples actions within the boundaries of social conventions.

3. Super Ego Incorporation within the personality of the moral standards and

value of parents, community and significant others.

PSCHOLOGICAL THEORIES OF CRIMEThe psychodynamic tradition links crime to a

manifestation of feelings of oppression and the inability to develop the proper psychological defenses and rationales to keep these feeling in control.

Attachment theory:John Bowlby

The ability to form an emotional bond to another person has important psychological implications that follow people across the life span.

PSCHOLOGICAL THEORIES OF CRIME2- THE BEHAVIORAL PERSPACTIVE: SOCIAL LEARNING THEORY

Behavioral perspective:Human action developed through learning experiences.People alter their behavior in accordance with the

response it elicits from other(supported by reward and extinguished by negative reaction).

Social learning theory:People learn to be aggressive by observing others

acting aggressively to achieve some goal or to being rewarded on violent act.

Watching violent TV shows makes kids behave more violently.

The evidence shows little association between viewing violent media and acting an antisocial ways.

PSCHOLOGICAL THEORIES OF CRIME3- COGNITIVE THEORYPsychological perspective that focus on the

mental processes by which people perceive represent the world around them and solve problems.

Criminal behavior patterns change over time as people mature and develop their reasoning powers.

Crime-prone people may have cognitive deficits and use information incorrectly when they make decisions

They view crime as an appropriate means to satisfy their immediate personal needs
