Q

KEY: what are the 4 possible reasons as to why lower IQ is related to higher levels of criminality?

A
  1. apprehension artifact
    - lower IQ = less concealing crime = greater rate of arrest
  2. IQs are lower bc of deliquent lifestyles
    - long study show lower IQ predicts subsequent criminality
  3. IQ effects mediated by poor scholastic achievement and social adjustment
    - true for minority but not majority
    - explains why most with lower IQ NOT involved in crime
    - dimmer switch
    - press = moderation
    - rotate = mediation
  4. lower IQ score merely correlated of deeper, more pervasive deficits
    - IQ differences underestimate true magnitude of more relevant deficits
    - school failure is a correlate

25
what were the results from Perry Preschool Project?
experimental group at age 19 had fewer arrests and more likely to be employed
26
what was the only thing that predicted delinquency?
Educational attainment - high correlation of r = 0.36
27
at age 27 what % of subjects had a diploma vs control?
71% for exp subject 54% for control
28
what type of school produces the fewest delinquents?
parochial schools
29
what type of school atmosphere produces the fewest delinquents?
warm but restrictive
30
what age does the brain reach about 90% adult size?
age 6
31
what age do girls brains reach full size?
11-12
32
what age do boys brains reach full size?
13
33
what does the brain fully develop?
25
34
proliferation
formation of new synaptic connections through learning
35
what period is for neural exuberance?
adolescence
36
what is neural exuberance?
where new connections are rapidly formed in response to environmental stimuli
37
what is pruning?
critical to brain maturation involving loss of unnecessary synaptic connection
38
how does pruning occur?
through myelination
39
what is myelination
growth of white matter that insulates neurons and makes brain more efficient
40
what is the reward center?
mesolimbic system
41
what releases dopamine into nucleus acumbens?
ventral tegmental area - affects motivation to pursue reward stimuli
42
what houses higher exec fxn?
PFC - dynamic filtering
43
what % of neurons are pruned when going from adol to adult and what does this lead to?
50 - greater capacity to defer gratification with lowered approach tendencies
44
what brain regions matures later than deeper brain structures?
PFC
45
what behaviors occur when PFC is developing?
- risk taking - short term goal directed behavior - neurons in mesolimbic pathway prune and gain control and reduce risk taking
46
what is maturing of PFC not about?
risk tolerance or inability to accurately calc risk - before adol ends they are intact
47
moderate CP is associated with _____
increased child aggressiveness
48
what were the results from Strauss and Mouradian?
- the higher the score the more aggressive they are + association
49
where does the most damage occur?
when going from never using CP to not in 6M
50
when done impulsively punishment contingency may be improperly structured why?
- CP may be perceived as fxn of parental instability - modeling effects - disrupt bonding - lowered self-esteem
51
what is CP associated with?
increased risk for mental health problems and diminished empathy later in life
52
what is suggested between responsible vs impulsive CP?
result in fewer neg effects - pos relationship between freq of CP and childrens' scores on antisocial behavior -> stronger when used impulsively
53
where are disproportionately high number of criminals coming from?
broken homes - highly confounded with other factors
54
what did Gove find?
children from intact but conflicted homes may be worse off - raised by single parents but in non-conflicted homes are less likely to become delinquents
55
what is the Butterfly effect?
- metaphor in chaos theory - apparent randomness - underlying patterns and causal forces at play
56
what is sensitive dependence on initial conditions?
small differences at one point can cause massive differences elsewhere
57
what is Moffit's model?
- crime committed by youth increases sharply between puberty and roughly age 18 - then most youth return to relatively crime-free lives (AL) - 5-6% go on to become career criminals into adulthood (LCP)
58
what is shown in LCP children?
higher incidence of ADHD and more liekly to come from homes with expsoure to RF
59
what are 3 RF in LCP children?
lower school performance problems in socializing parent-child interactions more likely to be strained - further abuse, brain damage, homes more likely to have low $ and low access to prof resources
60
what happens as LCP children develop?
- higher incidence of substance abuse - trouble accepting restrictions and limits - unplanned pregnancies - substandard educational attainment - lack of legal coping strategies - criminal records that limit future employment
61
what is key in LCP children?
early age onset
62
what happens with AL kids?
by the time they get into trouble the core set of social and academic skills are in place so smarten up
63
why do AL get in trouble?
lack of rites of passage - reaching adulthood is delated - maturational gao - try to close gap through illegal means
64
what happens as maturational gap closes naturally?
motivation to commit crime no longer exists - most antisocial behavior by teens drops after 17-18
