midterm Flashcards
definition of criminal behaviour
an intentional act or omission that is legally defined as a crime
process of defining crime as social and political in nature
social construction
crime is defined in a manner broadly agreed upon by society
consensus theory
crime is determined by socially powerful groups
conflict theory
type of violence committed to achieve a goal
instrumental violence
type of violence associated with presence of high emotional arousal
reactive violence
type of violence associated with victims who are strangers
instrumental violence
macro theory
explains things at a societal level
micro theory
explains things at an individual level
variations that exist between 2 or more persons
inter-individual differences
variations that exist within one person
intra-individual differences
why does the age-crime curve taper off during middle and old age
delinquency is often a passing phase during adolescence and early adulthood
limitation of descriptive research
provides no info about interrelationships of different variables
strength of classic experiment design
permits causal inferences
limitation of classic experiment design
extraneous factors which cannot be controlled might prevent us from making causal inferences
a research design that incorporates some features of a true experiment. can be used when random assignment is not possible
quasi-experiment
meta-analysis
combining results of many studies to generate statistical estimate of overall magnitude of findings
behavioural genetics
influence of genetics on expression of traits
evolutionary psychology
how natural selection shapes and influences mental processes and behaviour
polymorphism
a gene that exists in more than one form
allele
an alternative form of a gene that exists in more than one form
polygenic
a trait influenced by multiple genes
concordance rates of monozygotic twins who have committed crimes
80%
concordance rates of dizygotic twins who have committed crimes
60%
strength of twin studies
can show whether behavioural similarity is due to genetics or environment
strength of adoption studies
shows whether behaviour is influenced by biological or adopted parents
in the danish adoption study, what was the cause of the violence among 14 males over 4 generations?
a defect on the MAOA gene on the X chromosome which produces enzymes which breakdown neurotransmitters
What was grigorenko et al’s study?
examining 12 alleles of 4 genes among teens in prison and teens not in prison
what was the difference grigorenko et al found between the two groups they studied?
genetic differences re: dopamine function
what percent of individual variability does heredity represent?
40%
define diathesis
a genetic vulnerability or predisposition to develop a psychopathological condition
individuals exhibit gene-based differences in their sensitivity or reactivity to the environment
differential susceptibility model
healthy, caring, nurturing conditions which can lower risk of crime
protective factors
processes that raise or lower gene activity level without altering the genetic sequence
epigenetics
the set of conditions that existed during ancestral times and to which humans have adaptd
environment of evolutionary adaptiveness
acting in ways that increase your chances of surviving at the cost of someone else’s
selfishness
inclusive fitness
helping relatives see their genes pass on to more generations
reciprocal cooperation
providing a non-related individual a benefit on the basis that they will return the favour
cooperative behaviour was studied by whom? and what year
robert trivers, 1971
accepting a benefit without reciprocating
cheating behaviour
parenting effort
most reproductive effort invested in rearing offspring
mating effort
most reproductive effort invested in acquiring sexual partners
which of the alternative strategy theories promotes law breaking?
mating effort
a behavioural pattern that produces greater success when its use is rare
frequency-dependent strategy
relatively recent brain development
cerebral cortex
older brain structures
subcortex
general term for diseases that result in decreased mental funtioning
organic brain syndrome
violent offenders and sadistic sexual offenders have dysfunction in what area of the brain
frontal lobe
