Trait theories of Crime

Trade Theories in Criminology

Overview of Trait Theories

• Trait theories suggest that criminology is influenced by biological or psychological traits.

• These theories are divided into two main categories: biological makeup and psychological functioning.

Biological Trait Theory

• Focuses on the biological aspects of human behavior, including biochemical conditions that may predispose individuals to crime.

• Biochemical imbalances can lead to antisocial behavior, with factors like diet and environment playing significant roles.

• Conditions such as hypoglycemia can result in cognitive issues and increased aggression, leading to violent outbursts.

Hormonal Influences

• Hormonal changes, particularly elevated testosterone levels, are linked to increased aggression in both genders during adolescence.

Neuropsychological Factors

• Neurological impairments in areas like the prefrontal cortex are common among violent criminals and substance abusers.

• Attention Deficit Hyperactivity Disorder (ADHD) symptoms include impulsivity and lack of attention, which can contribute to delinquent behavior.

Genetic Influences on Behavior

• Antisocial behaviors may be inherited; genetic abnormalities can predispose children to similar behaviors as their parents.

• Studies indicate a correlation between parental criminality and delinquent behavior in offspring due to genetic factors.

Psychological Theories of Crime

Psychodynamic Model

• Sigmund Freud's model divides the mind into three parts: id (pleasure principle), ego (reality principle), and superego (moral conscience). This framework helps understand human drives and motivations related to crime.

Behavioral Perspective

• Social learning theory posits that behaviors are learned through experiences; exposure to violence can lead children to adopt similar aggressive behaviors. Evidence shows a link between watching violent media and acting violently themselves.

Cognitive Development in Criminal Behavior

• Criminal behavior patterns evolve over time; cognitive deficits may hinder proper information processing, contributing to antisocial actions as individuals mature.
