Abnormalities and disturbances in the temporal and prefrontal parts of the brain lead to inadequate and inappropriate ability to control oneâs behavior around children, including being actually able to complete sexual abuse.
Neurobehavioral models of pedophilia and child sexual offending suggest a pattern of temporal and in particular prefrontal disturbances leading to inappropriate behavioral control and subsequently an increased propensity to sexually offend against children.
Non-offending pedophiles had sufficient inhibition and generally commissioned less of the crimes, meaning, they generally premeditated or thought on the crimes less.
As compared to offending pedophiles, nonâoffending pedophiles exhibited superior inhibitory control as reflected by significantly lower rate of commission errors. Groupâbyâcondition interaction analysis also revealed inhibitionârelated activation in the left posterior cingulate and the left superior frontal cortex that distinguished between offending and nonâoffending pedophiles, while no significant differences were found between pedophiles and healthy controls. Both areas showing distinct activation pattern among pedophiles play a critical role in linking neural networks that relate to effective cognitive functioning.
Inhibition was therefore successful preventing the completion of cognitively commissioned crimes of sexual abuse.
Data therefore suggest that heightened inhibitionârelated recruitment of these areas as well as decreased amount of commission errors is related to better inhibitory control in pedophiles who successfully avoid committing handsâon sexual offences against children.

Pedophilia is defined as a sexual preference characterized by sexual attraction towards prepubertal or early pubertal children.
According to the 10th Edition of the International Statistical Classification System of Diseases and Related Health Problems (ICDâ10) [World Health Organization, 1992], pedophilia is defined as a sexual preference characterized by sexual attraction towards prepubertal or early pubertal children. In popular usage, pedophilia is often equated with child molestation, but clinically both phenomena can be distinguished.
Higher amygdala activation may signify the increased inhibitions that separate non-offending from offending pedophiles.
The only replicated finding is limited to an amygdala volume reduction in offending pedophiles
Intersections between nonsexual emotional functions and the processing of sexual stimuli were seen, which may explain the image distorting behavior that is seen specifically in pedophiles. Cognitive and executive functions were also seen.
. In this regard, Cantor et al. [2008, 2015] reported a partial dysconnectivity of regions that were identified to be reliably responsive to visual sexual stimuli [Poeppl et al., 2014; Stoléru et al., 2012]. While another study did not corroborate the latter findings [Gerwinn et al., 2015a], supportive evidence was provided by Poeppl et al. [2015] who identified a set of GM alterations related to offending pedophiles (including the right amygdala, left DLPFC, left insula, bilateral temporoparietal junction and the medial OFC) and demonstrated that these changes were functionally connected to key areas involved in the processing of sexual stimuli, nonsexual emotional functions, as well as in cognitive and executive functions.
Pedophiles have an overall slower processing speed and this was not on purpose, but because they have real fundamental neurocognitive impairments. Though they may try to spin it as chosen when outed to avoid embarrassment, the science suggests they arenât capable of going certain processing speeds. Why or how this relates to creating a pedophilic predisposition seems fruitful.
Pedophiles have an overall slower processing speed. Other recent studies demonstrated slower processing speed across a range of neuropsychological domains in offending pedophiles [Suchy et al., 2014, 2009] and provided evidence that this deficit may be related to fundamental neurocognitive impairments rather than a deliberate response style.
Inhibition-related alterations led to pedophiles having trouble keeping their attention focused on cognitively challenging tasks suggesting that when their attention collapsed, their inhibition was released. Violent or cathartic actions following broken attention may be fruitful for research as well as that would be a direct symptom of this inhibition-related alteration.
Pedophiles struggled to keep their focus on cognitively challenging tasks. The finding of inhibitionârelated alterations in brain areas which are part of the âDefault Mode Networkâ (DMN) [Buckner et al., 2008] seems noteworthy, suggesting that pedophiles may have problems keeping their attention focused during cognitively challenging tasks
Non-offending pedophiles had superior inhibitory control, meaning they were able to control themselves to not offend. This was due to stronger recruitment of stops on activation of the medial parietal cortex including the left caudal PCC as well as the left SFC.
As compared to offending pedophiles, nonâoffending pedophiles exhibited superior inhibitory control as reflected by a significantly lower rate of commission errors. In line with previous fMRI research [Blasi et al., 2006; Bari and Robbins, 2013; Simmonds et al., 2008], response inhibition led to stronger recruitment of a frontoâparietal control network (FPCN). Congruent with our hypothesis, offending pedophiles revealed decreased activation of the medial parietal cortex including the left caudal PCC as well as the left SFC as compared to nonâoffending pedophiles, but contrary to our hypotheses, showed no activation difference in prefrontal areas
Aberrant PCC Responses were found in pedophiles and responses were different for preferred sexual stimuli, such as higher response for pedophilic content. This aberrant response may be due to cognitive load, suggesting that pedophiles may be attracted to pedophilia because the cognitive load is lighter and requires less âcognitively expensiveâ inhibition. Whether this is a direct result of the environment surrounding children being less cognitively exhausting causing the pedophilic brain to be more attracted to it or something else at play would be fruitful for further research. Links between non-sexual emotions of cognitive overwhelm and heightened or decreased responsiveness due to sexuality circuits suggests this is very likely to be in fact the case. In fact, pedophiles may actively try to keep the subjects of their sexual attraction in low cognitive load environments to preserve their sexual attraction as only in these environments does their sexual responsiveness increase and may punish those they view sexually from leaving a low cognitive load environment out of sheer selfish desire to maintain that level of sexual responsiveness. This is again an area of fruitful future research.
The magnitude of hemodynamic responses in the PCC have been found to be associated with cognitive load in the healthy brain, while the inability of appropriate deactivation is related to disturbed cognitive function in the healthy as well as in the damaged brain [Leech and Sharp, 2014]. Moreover, aberrant PCC responses were reported in pedophile offenders during rest [KĂ€rgel et al., 2015] as well as during the processing of preferred sexual stimuli [Poeppl et al., 2011].
General processing deficit is behind much of the actual instantiation of sexual offense but does not seem to be related to aberrant sexual interests in general, showing that these compulsive acts are the failure and collapse of inhibitory mechanisms that for the pedophilic brain are more cognitively expensive to keep in place than the average individual. Essentially, it is like a weaker dam in the brain breaking more often and leading to fundamentally and deeply violating actions that have an âacting up/attackingâ quality.
The hypothesis that âcompensatoryâ engagement of the FPCN might help preventing pedophiles from sexual offending against children is quite speculative, but warrants further investigation. Interestingly, our findings of neurofunctional group differences in neural structures essential for efficient cognitive functioning may support the idea of a general processing deficit in offending pedophiles as proposed by Suchy et al. [2014], which, however, seems to be related to sexual offending behavior rather than aberrant sexual interests in general.
Individuals who can overcome their inhibitions or not weight correctly the negative consequences to the victim show an increased propensity to sexually approach victims. An increased ability to violate social norms is found on those who can complete sexual abuse.
It is suggested that only individuals who can overcome their inhibitions, e.g., worries about potential negative consequences on the victim, or fear to violate against social norms, would show an increased propensity to sexually approach victims.
Disinhibition is a relevant risk factor for sexual recidivism in general. Inhibitory control is the main difference between non-offending and offending pedophiles. Strengthening inhibitory circuits can prevent recidivism. Overall, ability to control impulses that ate at/tempted the individual differentiated the non-offending and offending pedophile. The offending pedophile was not able to be responsive to cognitive stops to sexual norm violation, evading them or not even ascertaining them to begin with. In the endâevasion or failure to even receive any such stops cognitivelyâthe result was the same so it didnât matter in the same way âwhite burdernistâ exterminationists donât differ from âuncivilizedâ pathological homicide when they both have the same result and inability to control. Only those who successfully inhibit their actions and listen to and internalize their stops of conscience, able to respect them enough to not evade them (which may itself be a product of intelligence understanding why these stops of conscience should be respected) would seperate non-offenders from offenders.
Although disinhibition has been reported a relevant risk factor for sexual recidivism in general [Hanson and MortonâBourgon, 2005; Mann et al., 2010], in line with previous research on personality traits [Cohen and Galynker, 2012] and cognitive functioning in pedophilia [Schiffer and Vonlaufen, 2011], our findings indicate that response inhibition abilities are not reduced in pedophilia per se. The present study rather extends the existing literature by providing some evidence that in pedophilia the ability not to offend against children might be associated with an elevated level of inhibitory control as well as an increased inhibitionârelated recruitment of the FPCN.
