1
Q

principles of life course criminology

A

Relation to other events; potential effect of any life event is determined by its relation to other events and its timing in the life course.

The meaning and consequence of any event for an individual is related to the prevailing social context and the life history of that person

Q

Empirical findings of stability

A

Virtually every study that includes measures of early problem behavior reveals that measurable individual differences predict variation in frequent, serious adult criminal behavior

Youths who engage in extremely high rates of misbehavior early in life are more likely to continue to engage in antisocial behavior
(Density hypothesis )

Youths who show ASB across settings, such as school and home, are more likely to continue their antisocial conduct

Youths who engage in a variety of antisocial acts, as opposed to a limited number of acts, are at increased risk of continuing ASB into the future (Variety hypothesis)

The earlier the onset of ASB, the more likely it is to continue

Highly aggressive behavior is found not only within individuals across settings but within families across generations
(Intergenerational continuity )

Levels of stability are higher for certain youths

Q

Evolutionary psychology psychological mechanisms

A

Humans use to process info and make decisions.

Information-processing procedure which evolution by natural and sexual selection has equipped humans to possess in order to solve an adaptive problem

21
Q

Natural selection

A

the process of differential survival

22
Q

sexual selection

A

the process of differential reproductive success

23
Q

principles of EP

A

Evolutionary theory is not shy about revealing the dark side of human nature: the ultimate goal of all life is reproductive success.
Ultimate goal of life is reproductive success
Negative traits, such as aggression, are something that was adapted along with other characteristics and traits needed to survive in the past.
(Positive characteristics also evolve in this way)

All human behavior requires both a mechanism (psychological) and an input (from the environment)

All psychological mechanisms owe their existence to evolution by selection
The only reason this and the bullet before exist is because of selection (sexual and natural) over time.

Humans are typically unaware of the evolutionary logic behind our psychological mechanisms
We are aware of the desires, values, preferences, and emotions that our psychological mechanisms engender in us and we consciously and rationally set about to pursue these goals within our constraints.

Evolved psychological mechanisms need only be adaptive in the environment in which they evolved, called the environment of evolutionary adaptedness or the ancestral environment.
The mechanisms only had to help out for a period in time.

To the extent that our current environment is radically different from the ancestral environment, our evolved psychological mechanism might produce maladaptive behavior.
Over time, some of the adaptations, such as aggression, may become behavioral problems.

Because our environment is so vastly different from the ancestral environment, we now face a curious situation where those who behave according to the dictates of the evolved psychological mechanisms are often worse off in terms of survival or reproductive success.

24
Q

Aggression as a solution to adaptive problems

A

As a means to co-opting the resources of others

As a defense against attack
Inflict costs on intrasexual rivals

Negotiate status and power hierarchies

Deter rivals from future aggression

Deter long-term mates from sexual infidelity

Reduce resources expended on unrelated children

25
Q

Agression as contest specific

A

Aggression is highly context-specific, triggered only in contexts in which the specific adaptive problems are confronted and the adaptive benefits are likely to be reaped.

Aggression is involved with the environment around that individual

26
Q

Why men, not women?

A

In all cultures studied to date, men are overwhelmingly more often the killers and their victims are mostly other men

Material sources and status improve men’s reproductive prospects much more than women’s

Crime can be identified with the behaviors that tend to promote mating effort and non-crime with those that tend to promote parenting effort

Males are more often the perpetrators of violence because they are the products of a long history of mild but sustained effective polygyny characterized by risky strategies of intrasexual competition for access to the high-investing sex.

Men are victims of aggression more than women because men are in competition primarily with other men
Other men interfere with their access to women, impede their access to resources needed to attract women, and other men provide strategic interference

When women use aggression against women, they typically use verbal aggression to lower the status of other women in the context of intrasexual competition
Physical imperfections, sexual promiscuity

27
Q

Why younger men, not older men?

A

No reproductive benefits from competition before puberty because prepubertal males are not able to translate competitive edge into reproductive success.

The benefits of puberty stay high for the remainder of their lives since human males are reproductively capable for most of their adult lives.

Before men start reproducing there are few costs of competition

After the birth of their first child, men’s energies and resources are put to better use by protecting and investing in their existing children.

28
Q

Purpose of behavioral genetics

A

Behavioral genetics (BG) examines both the genetic influences and environmental influences on the development of behaviors and traits

29
Q

Phenotypes

A

the observable characteristics of an individual resulting from the interaction of its genotype with the environment

30
Q

variance

A

a statistic that captures the degree of difference among people on a particular phenotypic measure

31
Q

heritability

A

estimates how much variation in a phenotypic trait is due to genetic variation among individuals in that population

32
Q

Shared environment

A

include any environments that are the same between siblings from the same household

Symbolized as c2

Makes siblings similar (parental SES, family size, neighborhood)

Focus of most criminology studies

33
Q

nonshared environment

A

include any environments that differ between siblings

Symbolized as e2

Makes siblings different (gender, birth order, illness, peer groups)

Includes both socialization(peer groups, parenting, schools, etc.) and non-socialization (prenatal environments) effects

34
Q

what do heritability estimates os antisocial behavior tell us about the environment

A

Genetic factors captured by heritability estimates can make siblings similar or different from each other

35
Q

broad heritability

A

Captures the effects that all sources of genetic variance have on phenotypic variance

36
Q

Narrow heritability

A

captures only the effects of additive genetic variance on phenotypic variance

37
Q

sources of genetic variance

A

Additive genetic varianc

Dominance (non-additive)

Epistasis (non-additive)

38
Q

Additive

A

Additive genetic variance is simply the sum of each gene’s contribution to phenotypic variance

Assumes that each gene’s effect on the phenotype is independent of all the other genes’ effects

All genes contribute equally to the final phenotype

39
Q

Dominance

A

Dominance effects capture the interaction between the alleles of one gene
Alleles are different copies of a gene

One gene contributes more or less to the final phenotype

40
Q

Epistasis

A

Epistasis captures the interaction between the alleles of two or more different genes

     An allele of one gene hides or masks the phenotype, or visual output, of another gene.
     Entirely different from dominance which applies to different alleles of the same gene (i.e. eye color, height)
     Epistatic mutations have different effects in combination rather than individually
41
Q

Benefits of Behavioral genetics over SSSMs

A

Include more than one child per family

Spuriousness, not taking into account biogenetic factors.

Able to separate genetic, shared environmental, and nonshared environmental effects

Assume genetic similarity varies across households

Looks at different levels of genetic relatedness

42
Q

monozygotic twins

A

Monozygotic (MZ) twins (aka identical twins) occur when one sperm fertilizes one egg, but then the fertilized egg splits to form 2 identical embryos
MZ twins share 100% of their genetic material

43
Q

dizygotic twins

A

Dizygotic (DZ) twins (aka fraternal twins) are the result of 2 separate eggs being fertilized by 2 separate sperms but implantation occurs during the same pregnancy
On average, DZ twins share about 50% of their genetic material

44
Q

findings of twin studies

A

Both MZ and DZ twins are assumed to share similar environments: same parents, same neighborhoods, same schools, same historical events

twin based research is flawed due to violations of EEA

45
Q

EEA

A

Equal-Environments Asumption refers to the assumption that twins from the same MZ twin pair have environments that are no more similar than twins from the same DZ twin pair

46
Q

MZA studies findings

A

MZ twins who are reared together are no more similar to each other when compared to twins who are reared apart:
MZ twins who are reared together are no more similar to each other when compared to twins who are reared apart

47
Q

Adoption studies

A

Adoptees who had a criminal biological parent and who had criminal adoptive parents had the highest rate of being convicted of a crime (24.5%)

Adoptees who had a criminal biological parent and a noncriminal adoptive parent had the second highest rate of being convicted of a crime
(20%)

Adoptees who had a criminal adoptive parent and a noncriminal biological parent had the third highest rate of being convicted of a crime, but just slightly (14.7%)

Adoptees with noncriminal biological and adoptive parents had the lowest rate of being convicted of a crime, but just barely (13.5%)

48
Q

family studies

A

Studies in this area produce heritability estimates that are consistent with those garnered from twin- and adoption-based research designs
