2 - Developmental and life course theories (L2, Moffitt, Laub & Sampson) Flashcards
There are two facts about antisocial behavior that the dual taxonomy presents. What are these two facts? (Moffitt)
- It shows impressive continuity over age;
- Its prevalence changes dramatically over age, increasing almost 10-fold temporarily during adolescence.
What is the dual taxonomy theory? (Moffitt)
Moffitt’s developmental taxonomy proposes that antisocial acts are committed by two very different ‘groups’ of people: A ‘life-course persistent’ group whose antisocial behavior onsets early in life and who become life-long offenders versus a larger ‘adolescence-limited’ group who offend during their teenage years.
Why did previous antisocial classification schemes failed? (Moffitt)
Because they offered relatively little in the way of etiological or predictive validity.
What does the theory about dual taxonomy need to say about delinquents whose criminal activity is confined to the adolescent years? (Moffitt)
The causal factors may be proximal, specific to the period of adolescent development, and the theory must account for the discontinuity in their lives.
What does the theory about dual taxonomy need to say about persons whose adolescent delinquency is merely one inflection in a continuous lifelong antisocial course? (Moffitt)
The theory must locate its causal factors early in their childhoods and must explain the continuity in their troubled lives.
Which is correct (Moffitt):
1. Does adolescence bring an increment in the number of people who are willing to offend?
2. Does the small and constant number of offenders simply generate more criminal acts while they are adolescent?
1: Empirical evaluations now suggest that the first explanation is correct.
What is the best predictor of long term recidivistic offending? (Moffitt)
Early arrest is important.
Does stability of antisocial behavior implies extremity? (Moffitt)
Yes, but extremity does not imply stability. The stability of antisocial behavior is closely linked to its extremity. The extreme frequency of crime committed by a very few males is impressive; it has been shown that the most persistent 5-6% of offenders are responsible for about 50% of known crimes.
What are the two hypothetical types of antisocial youth? (Moffitt)
- Life-course-persistent type
- Adolescence-limited type
What does life-course-persistent antisocial persons show across the life course? (Moffitt)
Exhibit changing manifestations of antisocial behavior: the underlying dispositions remains the same, but expression changes form as new social opportunities arise.
What is heterotypic continuity? (Moffitt)
it suggests that there is a common factor or attribute that leads to different kinds of actions or behaviors that we can see. Continuity of an inferred trait that is presumed to underlie diverse phenotypic behaviors. ????
Where do you look at in research if individuals’ antisocial behavior is stable? (Moffitt)
Roots early in life.
What is a possible source of neuropsychological variation that is linked to problem behavior? (Moffitt)
Disruption in the ontogenesis (= de ontwikkeling die elk individueel mens doormaakt van eicel tot in de volwassenheid en verder) of the fetal brain. Also child abuse and neglect -> brain injury.
What are two sorts of neuropsychological deficits associated with antisocial behavior? (Moffitt)
- Verbal deficits: these deficits of antisocial children are pervasive, affecting receptive listening and reading, problem solving, writing and memory.
- Executive deficits: these deficits produce learning disabilities, including symptoms such as inattention and impulsivity.
What is important to look for in children with cognitive and temperamental disadvantages? (Moffitt)
They are generally not born into supportive environments. And parents of children who are at risk for antisocial behavior often provide their children with criminogenic enviroments.
What form of interaction plays a important role in promoting antisocial behavior and maintaining its continuity? (Moffitt)
Evocative interaction. This occurs when a child’s behavior evokes distinctive responses from others.
What can a toddler’s problem behavior affect? (Moffitt)
- Parent’s disciplinary strategies
- Interactions with adults and peers at an older age
What are two additional types of interaction that may help explain how the LCP behavior might promote its own continuity and pervasiveness? (Moffitt)
- Reactive interaction: this occurs when different youngsters exposed to the same environment experience it, interpret it, and react to it in accordance with their particular style
- Proactive interaction: occurs when people select or create environments that support their styles
The three types of person-enviroment interactions (evocative, reactive, proactive) can produce two kinds of consequences in the life course. Which two? (Moffitt)
- Cumulative consequences: early individual differences may set in motion a downhill snowball of cumulative continuties
- Contemporary consequences: this happens if the LCP person continues to carry into adulthood the same underlying consellation of traits that got him into trouble as a child (e.g. poor selfcontrol)
Vul in (Moffitt). In this theory of life-course-persistent antisocial behavior neither …(1) nor …(2) account for continuity.
1: traits
2: environments
The life-course-persistent antisocial syndrome that suggest psychopathology. What are aspects of this syndrome? (Moffitt)
- The syndrome is statistically unusual; it affects about 5% of males.
- The syndrome is characterized by stability across time and in diverse circumstances. This high-probability response style is relied on even in situations where it is clearly inappropriate or disadvantageous.
- The syndrome has a biological basis in subtle dysfunctions of the nervous system.
- The syndrome is associated with other mental disorders (comorbid).
What is the hallmark of teenage delinquents (adolescent-limited delinquents) who have no notable history of antisocial behavior in childhood and little future for such behavior in adulthood? (Moffitt)
Discontinuity in adolescence-limited delinquents.
- May have crime free periods
- Lack consistency in antisocial behavior across situations
This type shows temporal instability and cross-situational inconsistency.
Why do adolescent-limited delinquents begin delinquency? (Moffitt)
Their delinquency is social mimicry of antisocial style of life-course-persistent youths. The resource is mature status, with its consequent power and privilege.
What is an explanation why boys will mimic life-course persistent boys? (Moffitt)
The maturity gap. They want to function more alike to their social age.
Why is personal independence a reinforcer of delinquent involvement by adolescent-limited? (Moffitt)
Every crime is a statement of personal independence. They want to prove that they can act independently.
