Criminological Theory The Search for the Criminal Man Revisited: Biosocial Theories Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Introduction By the 1960s, biology had lost much of its influence in criminological theory By the mid-1970s, interests emerged in newer biological approaches to criminality Publication of E.O. Wilson’s Sociobiology In the late 1970s, Lee Ellis and others were placing their hope for criminological theory in a biological or biosocial approach Some argued a specific genetic defect Explosion of work on DNA The Human Genome Project Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Introduction Ellis (1977) hearkened to scientific approaches that promised greater results in the future than sociological approaches Calls began for a “general systems theory” approach to social theory that would allow it to build upon biological foundations without falling into reductionism Call to be interdisciplinary With the resistance of many sociological oriented criminologists, it is clear that the current resurgence in biological theorizing will persist and grow in the foreseeable future Biosocial theorists suggest that biological traits interact with the social environment to shape human behavior Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Introduction Biosocial criminology is a “broader and more powerful” paradigm than sociological criminology and is likely to be the major paradigm of the 21st century More major “breakthroughs” are being hailed in biology, lending additional momentum to the few biologically oriented criminologists At both the beginning and the end of the 1990s indicated that about 85% of American criminologists remained strict environmentalists Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Introduction Biosocial criminologists risk being charged with racism and/or sexism in an atmosphere of political correctness Most biosocial criminologists reject the idea that biology translates into a predestined fate and instead suggests that genetic traits interact with the environment to shape human behavior Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Introduction Biosocial approaches may be categorized in terms of evolutionary psychology, neuroscience, and genetics Research compares biological risk factors to biological protective factors (an eco-biological approach) Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Evolutionary Psychology: Darwin Revisited Several new efforts to formulate theories based on evolutionary dictates Cheater theory: Some males have evolved “alternative reproductive strategies” to unconsciously ensure that their genes are passed on to succeeding generations Dads vs. cads Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Evolutionary Psychology: Darwin Revisited The cheater theory: Argues some males have evolved alternative reproductive strategies that unconsciously ensure their genes are passed to succeeding generations The r/K theory: Stresses that biological creatures vary in their approach to reproduction Cads v. Dad R= large number of offspring with no attachments K= slower reproduction with attachments Conditional adaptation theory: Maintains that antisocial behavior is part of an overall adaptive response to an unstable or hostile environment Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Evolutionary Psychology: Darwin Revisited Alternative adaptation theory: Some people inherit a greater tendency to engage in antisocial and are driven more by mating urges than by parenting urges Evolutionary expropriative theory: All humans have an equal genetic potential for antisocial behavior; humans are genetically driven to acquire resources to ensure reproduction Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Evolutionary Psychology: Darwin Revisited: Assessment Evolutionary theories are rarely as purely biological as the media make them appear; rather they are biosocial Darwin’s unit of analysis is the species and concerned with the process of natural selection Tendency for some evolutionary psychologists to write as if a trait that has survived must be ipso facto a desirable one, but those traits may be detrimental today Many evolutionary psychologists study the presumed evolution of “positive” traits such as empathy and altruism Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Evolutionary Psychology: Darwin Revisited: Assessment Within the past several decades evolutionary psychology has been dominated to some extent by a notion that departed from Darwin’s approach—that of the “selfish gene” Has come under increasing scrutiny in the past 30 years and evidence suggests that individual selection and group selection are operating simultaneously Evolutionary theories are hard to prove or disprove Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Social Concern Theory: Evolutionary Psychology Revisited Set forth by Agnew in 2013 A social concern has four elements: 1. 2. 3. 4. Care about the welfare of others Desire close ties to certain others Follow certain moral intuitions Conform to the behavior and views of others and to social norms, as well as sanction those who violate such norms Argues that social concern has a direct, negative effect on crime Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Social Concern Theory: Evolutionary Psychology Revisited Social concern can also have indirect, conditioning, and mediating effects on crime Individual and circumstantial factors can affect variation in levels of social concern Social concern is “natural” and has a substantial biological basis Emerged out of the evolutionary process that allows for cooperative behavior providing a major survival advantage Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Neuroscience: Neurological and Biochemical Theories The newer biosocial approaches tend to acknowledge the importance of learning, but they emphasize the extent to which the learning and conditioning of behavior occur differently for different individuals because of neurological or biochemical variants and the way in which the environment (including the womb) affects these neurological and biochemical variations, which are called polymorphisms Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Neuroscience: Neurological and Biochemical Theories Major neuroscientific theories of criminality include: Brain hemispheric theory: psychopaths rely less on right hemisphere and more on left Reward dominance theory: reward centers are more powerful than the inhibitory systems in criminals Prefrontal lobe theory Suboptimal arousal theory Seizuring theory: most controversial; seizures higher among offenders Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Neuroscience: Neurological and Biochemical Theories The newer biosocial theories have focused considerable attention on family studies aimed at locating genetic factors by examining behavioral similarities among members of the same family, although today they stress behavioral characteristics Twin studies are very common as well Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Mednick’s Biosocial Theory Mednick proposed that certain high-risks individuals inherited an autonomic nervous system (ANS) that is less sensitive to environmental stimuli which makes it less likely that they will develop the responses necessary to inhibit antisocial behavior Stresses that an individual with a normal ANS will experience a reduction of fear immediately on inhibiting antisocial activity and that, because this fear reduction is a powerful reinforcement, that person will learn to inhibit such activity Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Other Biosocial Theories Theories arguing for disorders of the central nervous system: Cortical immaturity hypothesis Hypoarousal hypothesis Suboptimal arousal theory – differences in ANS make people less sensitive to environmental stimuli Supported in EEGs “Hypoarousal” is measured by low pulse rate, low blood pressure, and reduced skin conductance of electricity Subjects characterized by hypoarousal show much lower responses to environmental stimuli than “normal” subjects Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Other Biosocial Theories Fearlessness theory: Low levels of arousal are markers for low levels of fear and that such fearless types are simply less likely to avoid situations that bring trouble with the law Stimulation theory: Such low arousal represents an unpleasant psychological state resulting in such types to seek out trouble to get sensory stimulation to avoid boredom Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Brain Development and Crime New techniques include computed tomography (CT), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), positron emission tomography (PET), and single photon emission tomography (SPECT) Biosocial criminologists have concentrated on the possibility that structural abnormalities of the brain may be associated with brain dysfunctions that are associated with criminal activity Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Brain Development and Crime Violence may be associated with frontal lobe dysfunction, whereas sex offenses may be associated with temporal lobe dysfunction Frontal lobes are associated with the executive cognitive functions Frontal lobe dysfunction hypothesis Left prefrontal lobe = positive affect; right prefrontal lobe = negative affect and withdrawal behavior Dorsolateral lobe damage = distractibility and poor executive functioning; orbitofrontal lobe = conduct disorder and antisocial personality disorder Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Brain Development and Crime The brain is a “triune system” consisting of the mid-brain (limbic system), R-complex (reticular activating system – RAS), and the prefrontal lobes Psychopaths have less activity in the RAS and more in the bilateral frontal temporal cortex Amygdalae are smaller in psychopaths making them less likely to feel a fear response and have trouble registering the fear of victims Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Brain Development and Crime Long history of tracing various forms of deviant behavior to the possibility of head injury The somatic marker hypothesis maintains that decision making entails both cognitive and emotional processing to evaluate the reward value of various behavioral choices, with “somatic markers” being formed in the brain as a consequence of various action-outcome sequences experienced in the past Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Biochemical Theories Fishbein has offered a theory that traces much of the problem of intractable offenders to an impaired hypothalamic-pituitary-adrenal axis (HPA), which has a negative effect on executive cognitive functions HPA impairment is associated with environmental stress Severe stress leads to increased cortical levels causing the structures comprising the HPA to shrink resulting in memory and cognitive decline Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Biochemical Theories Recent biochemical theories have focused on sex hormones and neurotransmitters Sex hormone theory has been concentrated on possible connections between testosterone and aggression Evolutionary neuroandrogenic theory of criminality: The biochemical effect of testosterone lowers neurological sensitivity to environmental stimuli, which is conducive to “acting out” and problems with emotional control, and it also tends to impair higher thought by producing a shift in the functioning of brain hemispheres Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Biochemical Theories Theorists have suggested that premenstrual syndrome (PMS) aw well as postpartum depression are the biochemical factors that affect women Other neurotransmitters identified by theorists and researchers linked to aggression are low levels of serotonin, low levels of dopamine, and high levels of norepinephrine Exercise of self-control needs sufficient glucose levels Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Biochemical Theories Reduced volume and surface deformations in the amygdalaes (along with differences in the middle frontal and orbitofrontal cortices) arefound in “unsuccessful” psychopaths with criminal convictions versus “successful” psychopaths who have avoided convictions Impulsiveness and negative emotionality are linked to low levels of serotonin, and there are now over 100 studies linking low levels of selfcontrol to low levels of serotonin Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Biochemical Theories The association between biochemical factors and antisocial behavior is hard to study Which came first? Time ordering issues Crime v. criminality According to Walsh criminality is the predisposition to engage in crime, while Turk defines criminality as a consequence of power struggles over which behavior should be regarded as crime Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Biochemical Theories Polymorphisms for genes regulating dopamine and serotonin have shown significant relationships to “criminality” Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Biochemical Theories One perplexing problem in criminology is the age-crime curve Evolutionary neuroandrogenic theory points to the dramatic biochemical increase in testosterone during male adolescence Juveniles have more dominant nucleus accumbens activity compared to the amount of activity in the prefrontal cortex (PFC) relative to younger children and adults Combined with increased testosterone increases likelihood of antisocial behavior and associated with dominance rather than aggression Dopamine rises in adolescence Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Biochemical Theories Moffitt’s life-course persistent (LCP) and adolescence-limited offenders (AL) LCPs have low IQ, hyperactivity, inattentiveness, negative emotionality, low impulsive control Neurological problems interacting with the environment leads to antisocial behavior ALs find antisocial behavior functional and adaptive Characterized as going through a phase Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Neuroscience: Assessment Advanced rapidly in the past two decades Gives us an understanding of why cognitive behavioral therapies are able to succeed with offenders Much work left to be done Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Genetics The genetic approach may be subdivided into behavior genetics, molecular genetics, and epigenetics Explore relationships between genotypes and phenotypes Genotypes – extent that traits are inherited Phenotypes – the processes in which the above occurs And how does the environment alter gene functioning without affecting the basic DNA Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Behavioral Genetics Tries to tease out the heritability component from the environmental contribution to various traits Significant heritability for fearlessness, aggressiveness, sensation seeking, impulsivity, and low IQ Began with the observation that females are less involved in antisocial behavior than males Males also tend to exhibit low self-control and are more aggressive in general Girls show fear earlier than boys Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Behavior Genetics Gender differences have suggested the genetic difference between males and females might be associated with crime Traces intervening variables that increase the likelihood of criminal activity Must remember, what is inherited is a tendency to respond to certain environmental forces in terms of general predispositions and not a specific behavior Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Molecular Genetics Molecular genetics focuses upon analysis of the detailed processes by which genetics has its effects upon traits and behaviors, with special attention to the deep molecular structure of substances such as deoxyribonucleic acid (DNA) There is nearly unanimous agreement that there is no such thing as a “gene” for crime Whether a genetic predisposition toward criminal activity is encouraged or discouraged depends upon the environment Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Molecular Genetics The relationship between gene and environment is referred to as the “gene × environment correlation” 1. Passive: Children inherit both their genes and their environment from their parents 2. Active: Reflect the tendency for people to seek out environments to which they are predisposed 3. Evocative: Different people also evoke different responses from their environments even when the latter are identical Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Epigenetics Environmental factors tend to alter gene functioning without affecting the molecular structure of DNA at all by activating or deactivating particular aspects Inheritance of characteristics acquired by parents that were never part of the gene pool Epigenome operates to adapt the organism to the particular environment in which it will find itself Epigenetics has shown that the diet of the pregnant woman may actually affect her grandchildren and great grandchildren Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Genetics: Assessment Behavior genetics, molecular genetics, and epigenetics focus on the search for relationships between genotypes and phenotypes Genotypes is a question of where to look for the “independent variable” that is associated with the traits and behaviors in which biosocial criminology is interested Biosocial criminologists now search for intervening variables that seem to link certain genotypes to general categories of law violation such as violent crime Exploring how certain genotypes tend to be associated with intervening variables such as “impulsivity” or “fearlessness” that might tend to lead to yet another intervening variable in the form of “antisocial behavior,” some of which may entail criminality IQ example Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications Conclusion Evolutionary psychology, neuroscience, and genetics have made significant contributions to biosocial theory within criminology Some criminologists have tended to react with almost reflexive resistance to this new criminological paradigm However, theorists need to work together and learn from one another Lilly, Cullen, Ball, Criminological Theory Sixth Edition. ©2015 SAGE Publications
