1) Biological theories Biological explanations of crime assume that some people are ‘born criminals’, who are physiologically distinct from non-criminals. The most famous proponent of this approach is Cesare Lombroso.

What biological factors contribute to criminal behavior?
Factors such as low intelligence, poor diet, impulsivity and hyperactivity, hormones such as testosterone and cortisol, and environmental pollutants may all affect a person’s biological propensity for criminal or antisocial behaviour.
What role do biological theories play in criminality and criminal behaviour?
Biological and Biosocial Theories: Addressing Root Causes Classical biological theories of criminality stated that people are “born criminals” who cannot be deterred from committing crimes: Whether due to mental or physical disability, criminals cannot learn to control themselves.
What are the approaches to criminal behavior?
Normative Approach: Objective Approach: It is an approach to criminology as to “what ought to be?” Objective Approach: Criminal behaviour when explained in terms of factors extraneous to the offender which are social, sociological, cultural and economic, the approach is called objective.
Which is an example of a biological theory of crime?
For example, studies have found general evidence for a connection between biology and criminality for both twins and adoptees. Twins are more likely to exhibit similar tendencies toward criminality if they are identical (monozygotic) than if they are fraternal (dizygotic).
Which theory best explains criminal behavior?
The theory of differential association, put forth by Edwin H. Sutherland (1), is a learning theory which formulates the process as one whereby criminal behavior is learned in association with those who have criminal attitudes and values, as compared to associations with those who have noncriminal attitudes and values.
What is the biological approach?
The biological approach believes behavior to be as a consequence of our genetics and physiology. It is the only approach in psychology that examines thoughts, feelings, and behaviors from a biological and thus physical point of view. Therefore, all that is psychological is first physiological.
What is the main concept of biological theory?
Biological Theory is devoted to theoretical advances in the fields of evolution and cognition with an emphasis on the conceptual integration afforded by evolutionary and developmental approaches.
What is an example of biological theory?
One example of a biological theory is the germ theory of disease. the germ theory of disease posits that certain microbes can make us ill if we are exposed to a certain amount of them and that some illnesses caused by certain microorganisms can be spread person-to-person.
What are the basic principles of biological theories of crime?
What are the basic principles of biological theories of crime? The basic principles of biological theories of crime say that behavioral predispositions, including aggression and criminality, are constitutionally or physiologically influenced.
What is biochemical theory in criminology?
IN RELATION TO CRIMINOLOGICAL THEORY, THESE BIOCHEMICAL THEORIES OF THE BRAIN AND BEHAVIOR SHOULD LEAD TO CERTAIN TYPES OF CONSIDERATIONS: (1) CRIMINAL BEHAVIOR MAY REPRESENT CERTAIN GENETIC PREDISPOSITIONS, CHROMOSOMAL ABNORMALITIES, OR METABOLIC ERRORS CREATING STRESS FACTORS IN A PERSON AND THUS, THE PROPENSITY TO …
What is the difference between psychological and biological theories of crime?
Biological theories have focused on body type, genetic factors, studies of twins to differentiate between genetic and social factors, and studies of chromosome variations. This literature suggests that criminality is genetically transmitted through the family. Psychological theories also focus on the individual.
What are the three theories of criminal behavior?
Broadly speaking, criminal behavior theories involve three categories of factors: psychological, biological, and social.
What are the 3 biological theories?
Biological theories can be classified into three types: (1) those that attempt to differentiate among individuals on the basis of certain innate (i.e., those with which you are born) outward physical traits or characteristics; (2) those that attempt to trace the source of differences to genetic or hereditary …
Is criminal behavior learned or genetic?
In general, results of behavioral genetic research indicates that up to 60% of variation in antisocial and criminal behavior is heritable, while shared environmental factors and nonshared environmental factors explain up to 10% and 50% of variance in criminal and antisocial behavior, respectively (see meta-analyses by …
Why is the biological approach important?
By looking at the biological bases of human behavior, psychologists are better able to understand how the brain and physiological processes might influence the way people think, act, and feel.
How do biological factors affect behavior?
A growing body of evidence suggests that biological factors such as genes, hormone levels, brain structure, and brain functioning influence the development and trajectory of conduct problems in youth.
Why is the biological approach useful?
Evaluation of the biological approach – Scanning research techniques are useful for investigating the functions of the brain: an organ with obvious involvement in our behaviour that would otherwise be unobservable. – The approach presents the strong nature viewpoint of the nature-nurture debate.
What is biological basis of behaviour?
Biological Bases for Behavior Key Terms Soma/cell body: The part of a neuron that contains its nucleus and other standard cellular structures. Dendrites: The multiple thin, treelike fibers that branch off from a neuron’s soma and contain receptors to accept incoming signals from other neurons.
What are the biological foundations of behavior?
Biological structures and processes serve as the pathways by which bodies carry out activities. They also affect predispositions to behave in certain ways, shape personalities, and influence the likelihood of developing psychological disorders.
How has the biological theory impacted the criminal justice system?
Degeneration Theory (1857) Degeneracy Theory, an offshoot of 19th century research into biological theories of crime, argues that certain (lower) social classes and races were predisposed to neurological and mental illnesses by inheritance, making them more likely to commit crimes.
What is biological in criminology?
Biological criminology. Biological criminology focuses on the physio- logical factors, not just genetic factors, which may be related to antisocial behavior.
What are 3 major biological theories of deviance and crime?
Starting from these basic assumptions, psychological explanations of deviant behavior come mainly from three theories: psychoanalytic theory, cognitive development theory, and learning theory.
Is criminal behavior due to nature or nurture?
One’s upbringing and social learning environment directly contribute to an individual’s specific criminogenic needs. Such needs are traits that lead to criminal behavior.
What are the strengths of the biological approach?
One strength of the biological approach is that it is deterministic. This is a strength because it increases the likelihood of being able to treat people with abnormal behavior and provides explanations about the causes of behavior. This understanding can then be used to improve people’s lives.
