Association of serotonin system-related genes with homicidal behavior and criminal aggression in a prison population of Pakistani Origin.

The serotonin transporter (SLC6A4), 5-HT2A (HTR2A) and 5-HT2B (HTR2B) recepter genes, express proteins that are important regulators of serotonin reuptake and signaling, and thereby may contribute to the pathogenesis of aggressive criminal behavior. 370 sentenced murderers in Pakistani prisons and 359 men without any history of violence or criminal delinquency were genotyped for six candidate polymorphisms in SLC6A4, HTR2A and HTR2B genes. An association of higher expressing L/L and LA/LA variants of the 5-HTTLPR polymorphism was observed with homicidal behavior (bi-allelic: OR = 1.29, p = 0.016, tri-allelic: OR = 1.32, p = 0.015) and in the murderer group only with response to verbal abuse (OR = 2.11, p = 0.015), but not with other measures of self-reported aggression. L/L and LA/LA genotypes of the 5-HTTLPR polymorphism were associated with higher aggression scores on STAX1 scale of aggression compared to lower expressing genotypes (S/S, S/LG, LG/LG) in prison inmates. No associations were apparent for other serotonergic gene polymorphisms analyzed. Using the Braineac and GTEx databases, we demonstrated significant eQTL based functional effects for rs25531 in HTTLPR and other serotonergic polymorphisms analyzed in different brain regions and peripheral tissues. In conclusion, these findings implicate SLC6A4* HTTLPR as a major genetic determinant associated with criminal aggression. Future studies are needed to replicate this finding and establish the biologic intermediate phenotypes mediating this relationship.

The GCAG Haplotype of the CRHBP Gene May Decrease the Risk for Robbery Behavior Among the Han Chinese.

Aims: Hypothalamic-pituitary-adrenocortical axis gene polymorphisms have been reported to affect aggressive behavior. Corticotropin releasing hormone binding protein (CRHBP) polymorphisms have been shown to contribute to the susceptibility to stress-related disorders, including aggressive behavior. However, no study has been conducted on the relationship between CRHBP polymorphisms and aggressive behavior risk in the Han Chinese population. Methods: A case-control study that comprised 194 male criminals and 303 healthy controls was carried out to investigate the genetic association between several CRHBP gene polymorphisms and aggressive behavior risk in the Hunan Han population. Genotyping was conducted by using the improved multiplex ligase detection reaction method for four CRHBP loci: rs10062367, rs32897, rs7718461, and rs7721799. Results: The incidence of the rs32897C allele was significantly lower in the robbery group compared with the control subjects after a Bonferroni correction (p = 0.016), indicating a protective role for the C allele of rs32897. Interestingly, a haplotypic analysis that was stratified by robbery and intentional injury showed that the haplotype consisting of rs10062367G, rs32897C, rs7718461A, and rs7721799G (which includes the protective rs32897 C allele) was significantly associated with decreased robbery risk (odds ratio [OR] = 0.31, p = 0.0005), but not for intentional injury (OR = 0.82, p = 0.44). The haplotype consisting of rs10062367G, rs32897T, rs7718461A, and rs7721799G carrying the rs32897 T allele significantly increased the risk for robbery (OR = 1.47, p = 0.0213), but not for intentional injury (OR = 0.92, p = 0.64). Conclusions: The rs32897 alleles and the haplotypes containing the rs32897 alleles, including GCAG and GTAG, may be factors associated with committing robbery in the Hunan Han population, and could be used to provide clinical counseling with regard to aggressive behavior. However, further studies including multiple ethnicities are needed.

Crystalline methamphetamine (ice) use prior to youth detention: A forensic concern or a public health issue?

Links between crystalline methamphetamine (CM) use and criminal offending are often drawn in the media; however, there has been little scientific research into this relationship. The aim of this study was to ascertain the prevalence and correlates of lifetime CM use among a sample of young people in detention in Australia and to examine whether an association exists between lifetime CM use and recidivism in this population.The sample included 202 young people (164 males) in youth detention in the state of Victoria, Australia. Participants were administered questionnaires related to lifetime substance use and socio-environmental experiences. Lifetime mental health data and offending data were obtained for each participant from public mental health and policing databases. More than one third (38%) of the sample reported lifetime CM use. In multivariate logistic regression analyses, older age, male gender, polysubstance use, and high levels of community disorganisation were associated with CM use. The presence of a psychiatric diagnosis over the lifetime was not significantly associated with CM use. CM use was also not significantly associated with violent recidivism. Efforts to address CM use and related harm in detained youth should include community-based strategies to reduce CM use among this vulnerable population following their release from detention. However, the findings suggest that CM use on its own is unlikely to be an important consideration for professionals concerned with determining which young people should be selected for treatment designed to reduce the risk of violent recidivism.

Association of Neuropathologically Confirmed Frontotemporal Dementia and Alzheimer Disease With Criminal and Socially Inappropriate Behavior in a Swedish Cohort.

Importance: Criminal and socially inappropriate behavior is encountered among patients with dementia, and it is sometimes the first sign of a dementing disorder. This behavior constitutes a significant burden to society, patients' relatives, and patients themselves. Objectives: To investigate and compare the prevalence and type of criminal and socially inappropriate behavior, as well as recurrence of criminal behavior, associated with Alzheimer disease (AD) and frontotemporal dementia (FTD) neuropathologically verified post mortem, and to assess whether there is a specific type of protein pathology more closely associated with criminal behavior in patients with FTD. Design, Setting, and Participants: Cohort study using medical record review of 220 Swedish patients with a postmortem neuropathologic diagnosis of AD (n = 101) or frontotemporal lobar degeneration (n = 119) (hereinafter referred to as FTD) diagnosed between January 1, 1967, and December 31, 2017. Main Outcomes and Measures: Patient notes containing reports of criminal and socially inappropriate behavior, as well as data on dominant protein pathology for patients with FTD, were duly reviewed and recorded. The Fisher exact test or logistic regression was used to assess possible differences between groups. Results: Of the 220 patients studied, 128 (58.2%) were female, the median (range) age at disease onset was 63 (30-88) years and at death was 72 (34-96) years, and the median (range) disease duration was 9 (1-28) years. Instances of criminal behavior were found in 65 of the 220 patients (29.5%): in 15 of the 101 patients (14.9%) with AD and 50 of the 119 patients (42.0%) with FTD (P < .001). Recurrence of criminal behavior was significantly higher in the FTD group (89.0%) than in the AD group (53.3%) (P = .04). Instances of socially inappropriate behavior were found in 57 patients (56.4%) with AD and 89 (74.8%) with FTD (P = .004). An expression of non-tau pathology increased the odds for criminal behavior by a factor of 9.0 (95% CI, 3.4-24.0) among patients with FTD. Conclusions and Relevance: These results suggest that criminal and socially inappropriate behaviors may be more prevalent and criminal behaviors may be more recurrent in patients with FTD than in those with AD. Non-tau pathology, but not tau pathology, appears to be associated with criminal behavior. These findings may help with the clinical diagnostic process.

Criminal offending and associated factors in dual diagnosis patients.

Dual diagnosis patients perpetrate crime more often than healthy individuals. Crime perpetration has major mental health consequences for the victim. Knowledge of factors related to perpetration is needed for the development of prevention programs. However, in dual diagnosis patients, very little is known about factors explaining criminal behavior. The current study investigated cross-sectional associations between demographic and clinical factors and perpetration of three crime types (violence, threat, and property crime) in 243 treatment-seeking dual diagnosis patients. In our sample, perpetration of violence was independently associated with younger age, severity of alcohol use problems, lifetime trauma exposure, and higher manic symptom scores. Expression of threat was independently associated with severity of alcohol use problems and higher manic symptom scores. Perpetration of property crime was independently associated with severity of alcohol and drug use problems. Remarkably, gender was not associated with any type of perpetration. These findings indicate that criminal offending is a significant problem among dual diagnosis patients and are a first step towards understanding the complex causal networks that lead to criminal perpetration. Future longitudinal research should investigate additional risk factors and establish causality to support the development of treatment programs to prevent criminal offending by dual diagnosis patients.

Diminished fronto-limbic functional connectivity in child sexual offenders.

BACKGROUND: Child sexual abuse and neglect have been related to an increased risk for the development of a wide range of behavioral, psychological, and sexual problems and increased rates of suicidal behavior. Contrary to the large amount of research focusing on the negative mental health consequences of child sexual abuse, very little is known about the characteristics of child sexual offenders and the neuronal underpinnings contributing to child sexual offending. METHODS AND SAMPLE: This study investigates differences in resting state functional connectivity (rs-FC) between non-pedophilic child sexual offenders (N = 20; CSO-P) and matched healthy controls (N = 20; HC) using a seed-based approach. The focus of this investigation of rs-FC in CSO-P was put on prefrontal and limbic regions highly relevant for emotional and behavioral processing. RESULTS: Results revealed a significant reduction of rs-FC between the right centromedial amygdala and the left dorsolateral prefrontal cortex in child sexual offenders compared to controls. CONCLUSION & RECOMMENDATIONS: Given that, in the healthy brain, there is a strong top-down inhibitory control of prefrontal over limbic structures, these results suggest that diminished rs-FC between the amygdala and the dorsolateral prefrontal cortex and may foster sexual deviance and sexual offending. A profound understanding of these concepts should contribute to a better understanding of the occurrence of child sexual offending, as well as further development of more differentiated and effective interventions.

Recognition of Facial Emotion and Affective Prosody in Children at High Risk of Criminal Behavior.

OBJECTIVE: Emotion recognition is an important aspect of emotion processing, which is needed for appropriate social behavior and normal socialization. Previous studies in adults with antisocial personality disorder or psychopathy, in those convicted of criminal behavior, or in children with conduct disorder show impairments in negative emotion recognition. The present study investigated affective facial and prosody recognition in a sample of children at high risk of developing future criminal behavior. METHODS: Participants were 8- to 12-year-old children at high risk of developing criminal behavior (N=219, 83.1% boys) and typically developing controls (N=43, 72.1% boys). The high-risk children were recruited through an ongoing early intervention project of the city of Amsterdam, that focuses on the underage siblings or children of delinquents, and those failing to attend school. Facial and vocal recognition of happy, sad, angry, and fear was measured with the Facial Emotion Recognition (FER) test and the prosody test of the Amsterdam Neuropsychological Tasks (ANT), respectively. RESULTS: The high-risk group was significantly worse in facial affect recognition and had particular problems with fear and sadness recognition. No hostile attribution bias was found. The high-risk group did not differ from controls in affective prosody recognition but needed significantly more time to recognize emotions. CONCLUSIONS: The emotion-specific deficits found in forensic and clinical populations are already present in a sample of children at high risk of developing future criminal behavior. These findings help us understand a possible underlying mechanism of antisocial behavior that could provide directions for tailored interventions. (JINS, 2019, 25, 57-64).

The Face as Diversity: What Was the Medical-Scientific Value of Lombrosian Morphoanthropology?

The face as an element of diversity. The ugliness of a face or a body and deformities were considered in 1800 as symbols of atavism, regression to being primates, or expression of inferior beings. The Italian physician Cesare Lombroso was the author of the concept of morphoanthropology, according to which the human being is judged on the basis of his or her physical connotations. The ugly person, with particular marks on his or her face and body, would be brought in as a criminal. Time has dissolved the value of Lombrosian theories, and scientific research has highlighted the influence of various factors in the genesis of crime. Genetic, biological, socioenvironmental factors, regulated by neurophysiology, which adds the effect of antagonism between the prefrontal cortex and the limbic cortex, explain the tendency to commit crime.

Predictors of adult outcomes in clinically- and legally-ascertained youth with externalizing problems.

Externalizing problems (EP), including rule-breaking, aggression, and criminal involvement, are highly prevalent during adolescence, but the adult outcomes of adolescents exhibiting EP are characterized by heterogeneity. Although many youths' EP subside after adolescence, others' persists into adulthood. Characterizing the development of severe EP is essential to prevention and intervention efforts. Multiple predictors of adult antisocial personality disorder (ASPD) and legal outcomes of a large sample (N = 1205) of clinically- or legally-ascertained adolescents (ages 12-19 years) with severe EP were examined. Many psychosocial predictors hypothesized to predict persistence of EP demonstrated zero-order associations with adult outcomes, but accounted for little unique variation after accounting for baseline conduct disorder symptoms (CD) and demographic factors. Baseline measures of intelligence, which explained independent variation in legal outcomes, provided the only consistent exception to this pattern, though future work is needed to parse these effects from those of socioeconomic factors. CD severity during adolescence is a parsimonious index of liability for persistence of EP into adulthood that explains outcome variance above and beyond all other demographic and psychosocial predictors in this sample.

Prevalence and Correlates of Criminal Behavior Among the Non-institutionalized Elderly: Results From the National Survey on Drug Use and Health.

OBJECTIVES: First to explore the prevalence of criminal behavior committed by the non-institutionalized geriatric American population. Second to determine the correlates of criminal behavior among this population. METHODS: We used data of the non-institutionalized adults aged ≥65 years in the National Survey on Drug Use and Health from 2008 through 2014. We compared socio-demographic and mental health profiles of arrestees to non-arrestees and lawbreakers to non-lawbreakers and then determined the correlates of being arrested and breaking the law through regression analyses. RESULTS: Around 0.4% of the population reported being arrested, and 5% reported breaking the law in the past year. The most prevalent offense was driving while intoxicated. Arrestees were significantly more likely to be male and to have had an alcohol or a drug(s) use disorder in the past year. Lawbreakers had a significant likelihood of being male, having a high educational level, and having an alcohol or a drug(s) use disorder in the past year. CONCLUSIONS: Elderly lawbreakers seem to have distinct characteristics that not just separate them from non-offenders but also probably from younger lawbreakers.

Neuroimaging Abnormalities in Neurological Patients with Criminal Behavior.

PURPOSE OF REVIEW: Criminal behavior occurs in previously law-abiding neurological patients, including patients with traumatic brain injury, focal brain lesions, and dementia. Neuroimaging abnormalities in these patients allow one to explore the potential neuroanatomical correlates of criminal behavior. However, this process has been challenging because (1) It is difficult to determine the temporal relationship between criminal behavior and neurological disease onset; (2) Abnormalities in several different brain regions have been associated with criminal behavior; and (3) It is difficult to quantify neuroimaging abnormalities in individual subjects. RECENT FINDINGS: Recent studies have begun to address these concerns, showing that neuroimaging abnormalities in patients with criminal behavior localize to a common brain network, rather than a single specific brain region. New methods have been developed to identify atrophy patterns in individual patients, but have not yet been used in neurological patients with criminal behavior. Future advances will be important for making sure that neuroimaging data is used in a responsible manner in legal cases involving criminal behavior.

Applying the Criminal Narrative Experience Framework to Young Offenders.

The present study applied the Criminal Narrative Experience for the first time with young offenders ( N = 23). The analysis was based on young people serving a community sentence and attending a Youth Offending Team. Participants completed questionnaires relating to their roles and emotions during a typical offence and data were examined with Smallest Space Analysis (SSA) to identify if the themes were replicated. Three themes were identified: Calm Professional, Elated Hero, and a combined theme of Distressed Revenger and Depressed Victim. Correlation indicated links between Narrative Experience and static and dynamic risk factors. Findings suggest that the Calm Professional theme correlates with Neighbourhood risk factors, the Elated Hero with Attitudes to Offending, and the Distressed Revenger/Depressed Victim theme with Living Arrangements and Family and Personal Relationships. Potential reasons for identifying three rather than four themes with this sample are discussed. Implications of findings in preventing reoffending are highlighted.

Violent and Non-Violent Criminal Behavior among Young Chinese Drug Users: A Mixed Methods Study.

Young drug users are found to be increasingly involved in criminal justice issues. This exploratory and descriptive study aims to analyze the criminal behaviors among young Chinese drug users through a mixed methods research design. Quantitative analysis indicates that young drug users with and without a history of criminality show significant differences in terms of several features. Male drug users, particularly, those who are older, with religious beliefs, and initiated into drug use at younger age were most likely to commit crimes. Among drug users with criminal experiences, those who committed crimes prior to drug initiation have a greater likelihood of committing violent crimes. Furthermore, young drug users with severe depression are more likely to commit crimes, especially violent ones. Qualitative analysis further illustrates that young male drug users often get involved in criminal conduct of the youth gang nature with propensity for engaging in violent crimes as compared to their female counterparts who are more likely to turn into drug dealers and traffickers, in addition to engaging in larceny. The research findings are consistent with developmental theories and "victim to offender cycle". Integrated mental health and substance use services are suggested for crime prevention among young Chinese drug users.

Born criminal? Differences in structural, functional and behavioural lateralization between criminals and noncriminals.

Over 100 years ago Lombroso [(1876/2006). Criminal man. Durham: Duke University Press] proposed a biological basis for criminality. Based on inspection of criminals' skulls he theorized that an imbalance of the cerebral hemispheres was amongst 18 distinguishing features of the criminal brain. Specifically, criminals were less lateralized than noncriminals. As the advent of neuroscientific techniques makes more fine-grained inspection of differences in brain structure and function possible, we review criminals' and noncriminals' structural, functional, and behavioural lateralization to evaluate the merits of Lombroso's thesis and investigate the evidence for the biological underpinning of criminal behaviour. Although the body of research is presently small, it appears consistent with Lombroso's proposal: criminal psychopaths' brains show atypical structural asymmetries, with reduced right hemisphere grey and white matter volumes, and abnormal interhemispheric connectivity. Functional asymmetries are also atypical, with criminal psychopaths showing a less lateralized cortical response than noncriminals across verbal, visuo-spatial, and emotional tasks. Finally, the incidence of non-right-handedness is higher in criminal than non-criminal populations, consistent with reduced cortical lateralization. Thus despite Lombroso's comparatively primitive and inferential research methods, his conclusion that criminals' lateralization differs from that of noncriminals is borne out by the neuroscientific research. How atypical cortical asymmetries predispose criminal behaviour remains to be determined.

Three Central Dimensions of Sexual Recidivism Risk: Understanding the Latent Constructs of Static-99R and Static-2002R.

The most commonly used risk assessment tools for predicting sexual violence focus almost exclusively on static, historical factors. Consequently, they are assumed to be unable to directly inform the selection of treatment targets, or evaluate change. However, researchers using latent variable models have identified three dimensions in static actuarial scales for sexual offenders: Sexual Criminality, General Criminality, and a third dimension centered on young age and aggression to strangers. In the current study, we examined the convergent and predictive validity of these dimensions, using psychological features of the offender (e.g., antisocial traits, hypersexuality) and recidivism outcomes. Results indicated that (a) Sexual Criminality was related to dysregulation of sexuality toward atypical objects, without intent to harm; (b) General Criminality was related to antisocial traits; and (c) Youthful Stranger Aggression was related to a clear intent to harm the victim. All three dimensions predicted sexual recidivism, although only General Criminality and Youthful Stranger Aggression predicted nonsexual recidivism. These results indicate that risk tools for sexual violence are multidimensional, and support a shift from an exclusive focus on total scores to consideration of subscales measuring psychologically meaningful constructs.

Psychosocial Correlates of Attitudes Toward Male Sexual Violence in a Sample of Financial Crime, Property Crime, General Violent, and Homicide Offenders.

Although those currently serving prison sentences for sexual violence can be identified and receive treatment, the number of prisoners with a history of sexual violence against female partners is unknown. Methods to identify prisoners with a proclivity for such violence and accurately assess the risk they pose before and after incarceration are therefore required. Here, we aimed to assess the level of sexually violent attitudes within dating relationships and to examine their associations with experiences of child abuse and neglect (CAN), psychopathic personality traits, prisonization, number of incarcerations, age, years of schooling, relationship status, and parenting among different types of offenders (financial crime, property crime, general violent, and homicide offenders). Data were collected among a large systematically selected sample of adult male inmates ( N = 1,123). We demonstrated that sexual violence-supportive attitudes appear to be a function of child sexual abuse and psychopathic personality traits, and may be developed through early socialization experiences as well as incarceration. Practical implications of current findings are discussed.

The Manitoba Youth Justice Program: empowering and supporting youth with FASD in conflict with the law.

Fetal alcohol spectrum disorder (FASD) describes a constellation of physical, cognitive, neurologic, and behavioral impairments resulting from prenatal exposure to alcohol. FASD is recognized as being one of the most common causes of preventable brain injury in children. There had long been concerns that some youth in conflict with the law may be affected with FASD given repetitive patterns of offending and apparent lack of understanding of the consequences of their actions. In 2004, funding was received from Justice Canada for a pilot project with a cross-departmental steering committee working together to determine a best way of working across systems to provide FASD assessments to these youth. It was recognized that provision of timely FASD assessments would allow the court to provide more meaningful sentences taking into account the youth's strengths and challenges and enhance the changes of decreased recidivism and increased changes of rehabilitation. This paper describes the basic science around FASD and its diagnosis, provides a history of the FASD Youth Justice Program, and reports on legal issues, structure, statistics, accomplishments, and ongoing future challenges.

Substance use, criminal behaviour and psychiatric symptoms following childhood traumatic brain injury: findings from the ALSPAC cohort.

Recent research suggests a link between traumatic brain injury (TBI) in youth and later risk behaviour. We explored the association between mild TBI and psychiatric symptoms, substance use and criminal behaviour using data from a longitudinal birth cohort. Participants with mild TBI (n = 800), orthopaedic injuries (n = 2305) and no injuries (n = 8307) were identified from self and parent reports up to age 16 years. Self-report measures of substance use (alcohol, tobacco and cannabis) and criminal behaviours, and parent-reported psychiatric symptoms were collected at age 17 years. Analyses were adjusted for pre-birth and early childhood confounders. Participants with a TBI showed increased odds of hazardous alcohol use compared to those with no injury and those with an orthopaedic injury. Relative to those with no injury, participants with a TBI showed increased odds of problematic use of tobacco and cannabis, being in trouble with the police and having more parent-reported conduct problems. Sustaining either a TBI or an orthopaedic injury increased the odds of offending behaviour compared to having no injuries. There was no clear evidence of association between orthopaedic injury and the other risk outcomes. The increased odds of risk behaviour associated with TBI relative to no injury replicated previous research. However, the inclusion of a non-brain-related injury group adds evidence for a possible causal pathway between mild TBI in youth and later hazardous alcohol use only. This highlights the importance of including an additional negative control injury group in mild TBI research.

Psychological treatment and therapeutic change in incarcerated rapists / Tratamiento psicológico y cambio terapéutico en agresores sexuales encarcelados

Most Spanish prisons provide specialised treatment for incarcerated sex offenders, both rapists and child molesters. This treatment is a cognitive-behavioural intervention that has shown relative effectiveness in previous research. With regard to offenders’ rehabilitation, recidivism assessments are necessary as a final measure of treatment effectiveness. However, the evaluation of recidivism by itself does not provide sufficient information on the treatment process and the specific effects that treated subjects could undergo. This paper aims to analyse the therapeutic effectiveness of psychological treatment provided to rapists (in general, males sentenced for committing a sexual offence against women). To this aim, a group of treated rapists (N=153) serving a sentence in prison was analysed. Using a specially designed scale (PASSO), the global therapeutic change and ten specific variables (including assertiveness, readiness to change, cognitive distortions, impulsivity, etc.) were assessed. The within-subjects comparison showed that treated sex offenders improved, in therapeutic terms, globally as well as in most of the specific variables assessed (improvements not experimented by the control group). Also, different therapeutic subscales showed relevant associations between them. The findings regarding treatment effectiveness are discussed (AU)

La mayoría de los centros penitenciarios españoles ofrecen un programa de tratamiento psicológico especializado para agresores sexuales, tanto para violadores como para abusadores de menores. Se trata de un programa de orientación cognitivo-conductual, que en algunas evaluaciones ya realizadas ha evidenciado una eficacia terapéutica relativa en términos de reducción de las tasas de reincidencia. Aunque la evaluación de la reincidencia delictiva sea una medida necesaria para ponderar la eficacia final del tratamiento de los agresores sexuales, dicha medida no permite conocer con precisión las mejoras específicas que los sujetos pueden experimentar. Este artículo dirige su atención precisamente a evaluar con detalle la eficacia terapéutica del tratamiento de los agresores sexuales de mujeres adultas. Con esta finalidad, se analiza una muestra de agresores sexuales tratados (N=153) que cumplen condena en prisión por un delito contra una mujer adulta. Para ello se evalúa mediante una escala diseñada al efecto (EPAS) el cambio terapéutico global de los sujetos tras el tratamiento y también su evolución en diez variables terapéuticas específicas (como asertividad, disposición al cambio personal, distorsiones cognitivas, etc.). La comparación intra-sujetos indicó que los agresores tratados mejoran, en términos terapéuticos, tanto globalmente como en la mayoría de las variables específicas evaluadas (mejoras que no se produjeron en el grupo control). Así mismo, se encontraron asociaciones significativas relevantes entre diversas variables terapéuticas. Finalmente, se comentan críticamente los resultados obtenidos y algunos de los retos existentes en el campo de la evaluación del tratamiento psicológico de los agresores sexuales (AU)

Why do people pirate? A neuroimaging investigation.

It is not uncommon for people to openly admit to pirating information from the internet despite the known legal consequences. Those same people are often less inclined to steal the same physical item from a shop. This raises the question, why do people have fewer reservations with stealing intangible items compared to tangible? Using questionnaires and fMRI we provide evidence across three studies as to the differences between tangible and intangible theft. In a questionnaire (Study 1), participants revealed that across different conditions they were more willing to steal intangible compared to tangible goods. Study 2a used fMRI to reveal that a network involved in imagining objects was more active when participants were representing intangible versus tangible objects, suggesting people have greater difficulty representing intangible items. Study 2b used fMRI to show that when stealing tangible objects versus intangible, participants had increased activation in left lateral orbitofrontal cortex, an area typically activated in response to morally laden situations. The findings from the current investigation provide novel insights into the higher prevalence of intangible theft and suggest that differential neural representation of tangible and intangible items may, in part, explain why people are more willing to steal intangible items.
