biological perspective on aggression

Violent offenders respond to provocations with high amygdala and striatal reactivity. However, amygdala maldevelopment can lead to a diminished ability to recognize distress or threat cues; disrupting the stimulus-reinforcement learning that discourages antisocial/criminal behavior (Blair, 2007; Sterzer, 2010). The Effects of Provocation and Fear of Death on Aggression, McGregor et al. In one experiment assessing the influence of serotonin on aggression, Berman, McCloskey, Fanning, Schumacher, and Coccaro (2009) first chose two groups of participants, one of which indicated that they had frequently engaged in aggression (temper outbursts, physical fighting, verbal aggression, assaults, and aggression toward objects) in the past, and a second group that reported that they had not engaged in aggressive behaviors. Hypo-arousal has been associated with impaired emotional intelligence (Ling et al., 2018a), but emotional intelligence training programs have shown some promise in reducing aggression and increasing empathy among adolescents and increasing emotional intelligence among adults (Castillo, Salguero, Fernandez-Berrocal, & Balluerka, 2013; Hodzic, Scharfen, Ropoll, Holling, & Zenasni, 2018), and in reducing recidivism (Megreya, 2015; Sharma, Prakash, Sengar, Chaudhury, & Singh, 2015). Thus, nutritional programs show some promise in reducing antisocial and criminal behavior. da Cunha-Bang S, Fisher PM, Hjordt LV, Perfalk E, Persson Skibsted A, Bock C, Knudsen GM (2017). Salivary testosterone and cortisol in delinquent and violent urban subculture. While there is evidence that antisocial/criminal individuals typically exhibit abnormal psychophysiological functioning, it is important to acknowledge that there are different antisocial/criminal subtypes, and they may not share the same deficits. 22, pp. A metaanalysis, MAOA, childhood maltreatment, and antisocial behavior: Metaanalysis of a gene-environment interaction. The aggressive participants who had been given serotonin, however, showed significantly reduced aggression levels during the game. Furthermore, if we enjoy engaging in the aggressive behavior, we may be rewarded, making us more likely to engage in it again. (Eds.). Rather, these students actually set a higher noise level and delivered longer bursts of noise than did the participants who did not get a chance to hit the punching bag. Implications of global climate change for violence in developed and developing countries. Federal government websites often end in .gov or .mil. A., Boechler, M., & McCaul, K. D. (1989). The health benefits of omega-3 polyunsaturated fatty acids: A review of the evidence, The frontal cortex and the criminal justice system, Philosophical Transactions of the Royal Society B: Biological Sciences. The .gov means its official. Similarly, while prefrontal volume deficits have been found in conventional criminals (i.e. Missy is an ill-behaved little girl. Berkowitz, L. (1989). The topics of aggression have been argued by many psychologists with different perspectives. Research has found that the cerebral cortex is less active in murderers and death row inmates, suggesting that violent crime may be caused at least in part by a failure or reduced ability to regulate emotions (Davidson, Jackson, & Kalin, 2000; Davidson, Putnam, & Larson, Figure 10.2 Key Brain Structures Involved in Regulating and Inhibiting Aggression. Perhaps not surprisingly, research has found that the consumption of alcohol increases aggression. Tottenham N, Hare TA, Millner A, Gilhooly T, Zevin JD, & Casey BJ (2011). Thus it would be expected that aggression is more likely to occur when we are more highly aroused, and indeed this is the case. What about deterrence? A recent meta-analysis has found clear evidence that people who are provoked but are unable to retaliate against the person who provoked them are more aggressive toward an innocent other person, and particularly toward people who are similar in appearance to the true source of the provocation, in comparison to those who were not previously provoked (Marcus-Newhall, Pedersen, Carlson, & Miller, 2000). Genetic and environmental influences on antisocial behavior: A meta-analysis of twin and adoption studies. Bethesda, MD 20894, Web Policies Another mechanism that could connect disrupted autonomic functioning to antisocial behavior is the failure to cognitively associate physiology responses with emotional states. Animals, especially males, are thought to be biologically programmed to fight over resources. Berkowitz, L. (1993). They emphasize the role of nature over nurture. Anderson, C. A., & DeLisi, M. (2011). Front Neuroendocrinol. Antisocial behavior and aggression were greater for children who had been severely maltreated, but this effect was even stronger for children with a gene variation that reduced the production of serotonin. Viding E, Sebastian CL, Dadds MR, Lockwood PL, Cecil CA, De Brito SA, & McCrory EJ (2012). Scandinavian Journal of Psychology, 12(4), 241248. Another way in which G x E interactions manifest themselves is when environmental stressors result in epigenetic changes, thus becoming embedded in biology that result in long-term symptomatic consequences. Differentiate emotional from instrumental aggression. The sight of a bottle of alcohol or an alcohol advertisement increases aggressive thoughts and hostile attributions about others (Bartholow & Heinz, 2006), and the belief that we have consumed alcohol increases aggression (Bgue et al., 2009). Disruption of PFC-amygdala connectivity has been linked to increased antisocial/criminal behavior, typically thought to be due to the impaired top-down regulation of amygdala functioning by the PFC. They were instructed to Please briefly describe the emotions that the thought of your next important exam arouses in you and to Jot down as specifically as you can, what you think will happen to you as you physically take your next exam, and once you are physically taking your next exam.. You can't turn a blind eye to the biology of violence and the social factors, too.' Mazur, A., Booth, A., & Dabbs, J. M. (1992). J Am Vet Med Assoc. The narrowing of attention that occurs when we are intoxicated also prevents us from being aware of the negative outcomes of our aggression. (1998). Theoretical and methodological considerations in cross-generational research on parenting and child aggressive behavior. A technical guide to tDCS, and related non-invasive brain stimulation tools. When we receive a poorer grade than our classmates received or when we are paid less than our coworkers, this can be frustrating to us. Frustration and aggression. look at her environment to see what elicits aggression and how it Summarize the effects of testosterone and serotonin on aggression. 2023 Jan 31;20(3):2549. doi: 10.3390/ijerph20032549. There is a growing literature on biological explanations of antisocial and criminal behavior. Hyde LW, Shaw DS, Murray L, Gard A, Hariri AR, & Forbes EE (2016). In general, research suggests that antisocial/criminal individuals tend to exhibit reduced brain volumes as well as impaired functioning and connectivity in key areas related to executive functions (Alvarez & Emory, 2006; Meijers, Harte, Meynen, & Cuijpers, 2017; Morgan & Lilienfeld, 2000), emotion regulation (Banks, Eddy, Angstadt, Nathan, & Phan, 2007; Eisenberg, 2000), decision-making (Coutlee & Huettel, 2012; Yechiam et al., 2008), and morality (Raine & Yang, 2006) while also exhibiting increased volumes and functional abnormalities in reward regions of the brain (Glenn & Yang, 2012; Korponay et al., 2017). WebBiological perspectives on aggression Prog Clin Biol Res. Genetic influences on adolescent behavior. So, in the 1950s, little toddlers were playing outside, putting their fingers in dirt, putting their fingers in their mouths and absorbing the lead. ', "You know, what about the victim? Behavioral genetics studies have found that criminal and aggressive behavior is correlated at about .7 for identical twins but only at about .4 for fraternal twins (Tellegen et al., 1988). Careers. Schiffer B, Muller BW, Scherbaum N, Hodgins S, Forsting M, Wiltfang J, Leygraf N (2011). Sharma N, Prakash O, Sengar KS, Chaudhury S, & Singh AR (2015). Spousal abusers have also been found to exhibit increased amygdala activation when responding to aggressive words compared to nonabusers (Lee, Chan, & Raine, 2008). government site. When the participants were given an opportunity to retaliate by giving shocks as part of an experiment on learning, those who had seen the positive cartoons gave fewer shocks than those who had seen the neutral pictures. For example, chromosomes and hormones (testosterone) influence our behavior, too, in addition to the environment. Autonomic stress reactivity and executive functions in successful and unsuccessful criminal psychopaths from the community. Acute alcohol consumption is more likely to facilitate aggression in people with low, rather than high, executive functioning abilities. Brain Behavior and Evolution, 59, 1020. The aggression levels for the more aggressive participants increased over the course of the experiment for those who did not take a dosage of serotonin but aggression did not significantly increase for those who had taken serotonin. A growing body of literature has indicated the importance of considering neurobiological factors in the etiology of antisocial and criminal behavior. Although much more research is needed, it appears that aggressive behavior, like most other behaviors, is affected by an interaction between genetic and environmental variations.

The return of Phineas Gage: Clues about the brain from the skull of a famous patient. Both capture autonomic nervous system functioning; skin conductance reflects sympathetic nervous system functioning while heart rate reflects both sympathetic and parasympathetic nervous system activity. Schweiz Arch Neurol Neurochir Psychiatr. A longitudinal study of resting heart rate and violent criminality in more than 700000 men, Strong limbic and weak frontal activation in aggressive stimuli in spouse abusers. Alternatively, the sensation-seeking hypothesis suggests that blunted psychophysiology is an uncomfortable state of being, and in order to achieve homeostasis, individuals engage in antisocial behavior to raise their arousal levels (Portnoy et al., 2014; Raine, 2002). Then they convinced them that another participant had read the article and provided very negative feedback about it. Gesch CB, Hammond SM, Hampson SE, Eves A, & Crowder MJ (2002). A study of 17 patients who developed criminal behavior following a brain lesion documented that while these lesions were in different locations, they were all connected functionally to regions activated by moral decisionmaking (Darby, Horn, Cushman, & Fox, 2018), suggesting that disruption of a neuromoral network is associated with criminality. The ability to aggress is part of the evolutionary adaptation of humans. Temperature and aggression. Impairments in autonomic functioning could lead to risky or inappropriate behavior if individuals are unable to experience or label somatic changes and connect them to relevant emotional experiences. One important consideration for future studies is to determine a consistent operationalization for the striatum, as some studies examine the dorsal striatum (i.e. Do early childhood interventions prevent child maltreatment? Journal of Experimental Social Psychology, 10(1), 2333. I don't want excuses. Vestlund J, Zhang Q, Shevchouk OT, Hovey D, Sebastian L, Westberg L, Jerlhag E. Transl Psychiatry. Engaging in aggression causes temporary increases in testosterone. You just think, 'That's crazy, having the death penalty.' Polaschek DLL, & Skeem JL (2018). When they arrived at the lab they were asked to write a short paragraph describing their opinion of politics in the United States. In addition, half of the participants (the mortality salient condition) were asked to briefly describe the emotions that the thought of your own death arouses in you and to Jot down as specifically as you can, what you think will happen to you as you physically die, and once you are physically dead. Participants in the exam control condition also thought about a negative event, but not one associated with a fear of death. WebRole of the Nervous System Proponents of the biological perspective view mental illness as being a result of a malfunction in the body to include issues with brain anatomy or chemistry. Woods AJ, Antal A, Bikson M, Boggio PS, Brunoni AR,Celnik P, Knotkova H (2016). It must be kept in mind that the observed relationships between testosterone levels and aggressive behavior that have been found in these studies cannot prove that testosterone causes aggressionthe relationships are only correlational. During the task, the person who won each trial could punish the loser of the trial by administering electric shocks to the finger. A threat to ones worldview increased aggression but only for participants who had been thinking about their own death. Journal of Social Psychology, 136(1), 4956. But there's a Mr. Hyde inside of me ranting and raving and saying, 'Look, I don't want sob stories. The most well-known example of the effects of prefrontal lobe lesions is the case of Phineas Gage, who was reported to have a dramatic personality change after an iron rod was shot through his skull and damaged his left and right prefrontal cortices (Damasio, Grabowski, Frank, Galaburda, & Damasio, 1994; Harlow, 1848, 1868). Page 6. The biological perspective looks at physiological responses from a biological standpoint, factors such as genes and neurotransmitters. HHS Vulnerability Disclosure, Help 8600 Rockville Pike Alcohol and social behavior: I. Baird A, Candy B, Flouri E, Tyler N, Hassiotis A. Int J Environ Res Public Health. While a detailed summary is beyond the scope of this review, some interactions between biological mechanisms are briefly illustrated here. 2016. Disclaimer. Emphasizes the effects of experience on behavior. Biological psychology states that all behavior has a physical/organic cause. The neuromoral theory of antisocial behavior, first proposed by Raine and Yang (2006), argued that the diverse brain regions impaired in offenders overlap significantly with brain regions involved in moral decision-making. Consider a time when you or someone you know engaged in an aggressive act with the goal of reducing further aggression (catharsis). We get frustrated when our computer crashes while we are writing an important paper, when we feel that our social relationships are not going well, or when our schoolwork is going poorly. Choy O, Raine A, Venables PH, & Farrington DP (2017). WebThis chapter describes a number of biological theories of violence in order to provide a general framework for the following chapters on the neuropsychology of aggression. For example, females exposed to childhood sex abuse have exhibited alterations in the methylation of the 5HTT promoter region, which in turn has been linked to subsequent antisocial personality disorder symptoms (Beach, Brody, Todorov, Gunter, & Philibert, 2011). and transmitted securely. ), Advances in experimental social psychology (Vol. In M.

Fergusson DM, Boden JM, & Horwood LJ (2011). This relationship seems to be weaker among humans than among animals, yet it is still significant (Dabbs, Hargrove, & Heusel, 1996). doi: 10.7554/eLife.77968. Neural connectivity during reward expectation dissociates psychopathic criminals from non-criminal individuals with high impulsive/antisocial psychopathic traits. Twenty years later, they became the next generation of violent criminal offenders because violence peaks at about 19 or 20. Effects of alcohol on human aggression: An integrative research review. Journal of Personality and Social Psychology, 81(1), 1732. And we may aggress when we feel that our social status is threatened. Indeed, while reduced amygdala volume in adulthood has been associated with increased aggressive and psychopathic characteristics from childhood to early adulthood, it is also associated with increased risk for future antisocial and psychopathic behavior (Pardini, Raine, Erickson, & Loeber, 2014). On the biological basis of sex differences in aggression. Longitudinal studies have found low resting heart rate in adolescence to be associated with increased risk for criminality in adulthood (Latvala, Kuja-Halkola, Almqvist, Larsson, & Lichtenstein, 2015; Raine, Venables, & Williams, 1990). The .gov means its official. Epigenetic studies on aggression have associated non-genetic risk factors with modifications of the stress response and the immune system. One prediction that could be derived from the catharsis idea is that countries that are currently fighting wars would show less domestic aggression than those that are not. Research suggests the former may exhibit amygdala hypoactivity and the latter, amygdala hyperactivity (Raine, 2018a). A healthy social environment is also crucial for normative brain development and function. There's a cause for all behavior. Web10.1 Defining Aggression Learning Objectives Define aggression and violence as social psychologists do. Social and neural determinants of aggressive behavior: pharmacotherapeutic targets at serotonin, dopamine and gamma-aminobutyric acid systems. Aggression is an evolutionary conserved behavior present in most species including humans. Inadequate aggression can lead to long-term detrimental personal and societal effects. Here, we differentiate between proactive and reactive forms of aggression and review the genetic determinants of it. Herit The neurobiological basis of human aggression: A review on genetic and epigenetic mechanisms Aggression is an evolutionary conserved behavior present in most species including humans. Inadequate aggression can lead to long-term detrimental personal and societal effects. the contents by NLM or the National Institutes of Health. While biological processes can contribute to antisocial/criminal behavior, these do not guarantee negative outcomes. Coie, J. D., & Dodge, K. A. Evolution of human intelligence: The roles of brain size and mental construction. In this review, we summarize the current knowledge of the genetics of human aggression based on twin studies, genetic association studies, animal models, and epigenetic analyses with the aim to differentiate between mechanisms associated with proactive or reactive aggression. Even the number of baseball batters hit by pitches is higher when the temperature at the game is higher (Reifman, Larrick, & Fein, 1991). 2022;40(3-4):268-281. doi: 10.1080/26896583.2022.2157183. Psychological Bulletin, 120(1), 6082. 2022. Using transcranial electric stimulation, upregulation of the PFC has been found to decrease criminal intentions and increase perceptions of moral wrongfulness of aggressive acts (Choy, Raine, & Hamilton, 2018), providing support for the causal influence of the PFC on criminal behavior. 2005 Oct;24(4):845-52, ix.

Additionally, high-MAOA may protect abused and neglected Caucasians from increased risk of becoming violent or antisocial, but this buffering effect was not found for abused and neglected non-Caucasians (Widom & Brzustowicz, 2006). While more research is needed, current literature suggests that striatal deviations are linked to criminal behavior. Dysfunction in the striatum has been hypothesized to be a neural mechanism that underlies the impulsive/antisocial behavior of criminals. However, structural deficits and functional impairments of the PFC have been observed in antisocial and criminal individuals, suggesting that PFC aberrations may underlie some of the observed behaviors. 2009 May 15;234(10):1253-4; author reply 1255.

Despite differences among subgroups, dysfunctional autonomic functioning generally remains a reasonably well-replicated and robust correlate of antisocial and criminal behavior. Neugebauer R, Hoek HW, & Susser E (1999). ", On reconciling the victim part of him with the criminologist part of him, "I'm a Jekyll and Hyde. And to me, it's the only single cause that can both explain the precipitous rise in violence from the '70s, '80s and '90s and also the drop that we've been experiencing. I think in my life, for example, I had parents who sort of loved me. Yang Y, Raine A, Lencz T, Bihrle S, LaCasse L, & Colletti P (2005).

FOIA Journal of Personality and Social Psychology, 74(3), 590605. Whereas individuals who are high on proactive aggression may be more likely to exhibit blunted autonomic functioning, individuals who are high on reactive aggression (an affective form of aggression that is elicited as a response to perceived provocation) may be more likely to exhibit hyperactive autonomic functioning (Hubbard, McAuliffe, Morrow, & Romano, 2010; Vitiello & Stoff, 1997). "Just as there's a biological basis for schizophrenia and anxiety disorders and depression, I'm saying here there's a biological basis also to recidivistic violent offending," Raine, a professor at the University of Pennsylvania and author of the book The Anatomy of Violence: The Biological Roots of Crime, tells Fresh Air's Terry Gross.
