1. Developmental Theories
Life-course perspective
Latent Trait perspective

2. Why do we need developmental theories?
Can criminologists be satisfied with existing theories?
Each of the theories tries to explain between individual differences

3. Why do we need developmental theories?
What about within individual differences?
Do you believe that people do not change?

4. Life course theory
Life is a dynamic process. As people travel through the life course they are bombarded by changing perceptions and experiences and as a result their behavior will change directions (sometimes for better and sometimes for worse)

5. Developmental theories
Common tendencies in development
You can predict what a person went through
Do not ask the “relatively simple” questions: Why do people commit crime? Or Why do some people desist from crime?
They want to know how the criminal behavior changes over the life course
What are the possible scenarios?

6. Age-graded Theory
8-9 years
15-24 years
45-55 years

7. Age and Crime Age is inversely related to criminality
Younger people (regardless class, race, sex) commit crime more often than their older peers

8. Dynamics of criminal behavior (can you think of any theories that could explain these scenarios?)

9. DEVELOPMENTAL THEORIES
LATENT TRAIT THEORIES
The General Theory of Crime: Gottfredson and Hirschi
The Differential Coercion Theory: Colvin
The Control Balance Theory: Tittle
LIFE COURSE THEORIES
Age-Graded Theory: Sampson and Laub
Theory of Delinquent Development: Farrington
Interactional Theory: Thornberry

10. LATENT TRAIT THEORY
Master Trait: Personal attributes present at birth or established early in life, and it remains stable over time, i.e., personality, intelligence, and genetic traits
Personal traits do not change
Criminal opportunities change
Maturity brings less opportunity
Early social control and proper parenting can reduce criminal propensity

11. Mark Colvin-Differential coercion theory
Control varies along two continua and dimensions:
Non-coercive and consistent
Non-coercive and erratic
Coercive and consistent
Coercive and erratic
Likelihood of crime and deviance varies according to the amount of coercion experienced

12. Age-Graded Life-Course Theory
Causal relationship between early delinquent offending and later adult deviant behavior is not solely a product of individual characteristics
Social events may change some individuals while others continue to offend
Informal social bonds to family and employment during adulthood explain changes in criminality

13. Age-Graded Life-Course Theory

14. Life-course model
Social bonds created by strong attachment to a spouse, military, job stability and commitment, and employee-employer interdependence reduce crime
The social ties embedded in adult transitions (i.e. marital attachment and job stability) explain variations in crime

15. Farrignton’s Developmental Theory
Cambridge Study (longitudinal study of 411 London boys)
Persistent offenders start at 8 years old (property crimes)
Poor parental supervision, delinquent friends,, aggressiveness are the factors that predict the future offending

16. Farrignton’s desisters
Shy personality
Having few friends (at age 8)
Having nondeviant families
Being highly regarded by their mothers
Social bond variables (similar to Sampson and Laub’s theory)

17. Interactional Theory Terence Thornberry (1987)
Interactions are very important in shaping the behavior
Attachment to parents, peers, social institutions change over time
Further, delinquents not only are influenced by their social surroundings but also have an impact on others through their behavior

18. Thornberry’s Model Interactive or reciprocal
The base for the model came from control theory and social learning theory
“Fundamental cause of delinquency lies in the weakening of social constrains over the conduct of the individuals”
Next step is association with delinquent peers
This association foster delinquent values and delinquent behavior

19. Thornberry’s Model 1 3
Weak parental
attachment
Delinquent
association
Delinquent
behavior 2 4 5 6
This model answers the contradiction between Social Learning theory and Control theory about what goes first: deviant behavior or association with delinquent peers.

20. Thornberry’s Model
Interactional process creates a “behavioral trajectory” that “predicts increasing involvement in delinquency and crime”
Initial weak bonds lead to high delinquency, the high delinquency further weakens the conventional bonds
Combination of these effects make it difficult to reestablish bonds to conventional society at later age

21. Thornberry’s Model
What about effect of employment, college, military, and marriage?
These variables play an important role in determining whether delinquency will continue or desist

22. Patterson’s Social-Interactional Developmental Model (1989)
Children and their environment are in constant interchange
The start of antisocial behavior happens in dysfunctional families (harsh and inconsistent discipline, little positive parental involvement, poor monitoring)
Family members directly “train” the child to perform antisocial behaviors

23. Patterson’s Social-Interactional Developmental Model (1989)
In dysfunctional families, coercion is a way of life
Child might see that only coercion can stop other family members from employing hitting
Antisocial children manifest “conduct problems” outside the home (rejected by peers)
Later they gravitate toward “deviant peer groups”
This association reinforces delinquent behavior
Later these children will have dysfunctional families and promote coercion

24. Tittle’s Control Balance Theory
Control theorists focus on the factors that “restrain” the behavior of individuals
Tittle made an innovation by arguing that people are not only objects of control but also agents of control
Each person has a certain amount of control that she/she is under and a certain amount of control she/he exerts

25. Tittle’s Control Balance Theory
Tittle sought to have a “General Theory” and thus to explain all forms of deviance
For some, the relative amount of control is in balance (Control Balance )
Some suffer from deficit of control and others experience a control surplus (Control Imbalance)
Control balance is associated with conformity and Control imbalance tends to be associated with deviance

26. Tittle’s Control Balance Theory
Exploitation
Submission
Defiance
Predation
Balance
Plunder
Decadence
Conformity
Repression
Autonomy

27. Tittle’s Control Balance Theory
White-collar crimes
vandalism
Serious forms of crime
Exploitation
Submission
Defiance
Predation
Balance
Plunder
Decadence
Conformity
Repression
Autonomy

28. Tittle’s Control Balance Theory
Predisposition to deviance is in each of us
Human nature has a strong urge for autonomy (to escape the control that others wish to impose on us)
Motivation appears when two conditions transpire: a person becomes aware of his/her control imbalance and realize that deviant behavior can change this imbalance and person must experience" negative emotion” of being humiliated or denigrated

29. Tittle’s Control Balance Theory
Once motivation has emerged, deviant behavior still might not occur
Opportunity must be present
Constraints (fear of being caught, moral ambitions, social bonds) also must be overcome
