Actually most of your comments are bogus. You copying selected bits from the studies, while ignoring the researchers findings and statements. And you are lying in several places, such as saying they didn't stdudy porn addicts. Luckily everyone can see what the studies say, and waht the researchers say. All the studies align with the TEDx talk and support many of it's claims.
Your comments about internet addictions are silly: audio visual stimuli is capable of leading to addiction, and associated brain changes. Since sexual stimuli release far higher dopamine that any other natural stimulus, it ssilly to suggest that Internet porn could cause addiction.
That study had little to do with pornography. It's measure was compulsive sexual behaviour (which includes everything sexual). You cannot just state that this is porn addiction because it is not. It's compulsive behaviour. Complusive behaviour is only a subbehaviour of addiction.
That's a lie, and everyone can read for themselves that your are lying.. CSB is umbrella term, but the study only selected compulsive porn users, and uses porn as the stimulus, and all the men claimed to be addicted to porn.
Enhanced Attentional Bias towards Sexually Explicit Cues in Individuals with and without Compulsive Sexual Behaviours (2014) Again sexual compulsive behaviour. That is what they are measuring as the independent variable. Lying. It was only men who could not control porn use, and that porn use had caused negative consequences.
Brain Structure and Functional Connectivity Associated With Pornography Consumption: The Brain on Porn. Did Gary not read this final conclusion?
Did you not read everything before the conclusion, and the comments by the author. All above. Everyone can see that the real neuroscientist disagree with your spin. Hours plus YEARS of use... remember.
Said the study, "This is in line with the hypothesis that intense exposure to pornographic stimuli results in a downregulation of the natural neural response to sexual stimuli."
Addiction and Porn Addiction. Internet Addiction has been shown to cause changes in the striatum etc. Therefore, they could not state whether the changes in striatum volume were due to pornography or internet use itself. Therefore it is inconclusive whether 'porn' causes changes in the brain.
Another lie. They controlled for Internet addiction. QUOTES:
To control for effects of Internet addiction, we used the Internet Addiction Test
Even when controlling for Internet addiction, we found a negative association between PHs and the right caudate GM volume
Lets not forget that with the 2 studies that he uses to implicate in Erectile Dysfunction were looking at Compulsive Sexual Behaviour (THIS IS NOT COMPULSIVE PORN USE).
A lie. CSB is a general term. They were recruted using ads for men who had porn addiction. It was compulsive porn use and everyone knows it. AS the subjects said -
CSB subjects reported that as a result of excessive use of sexually explicit materials..... experienced diminished libido or erectile function specifically in physical relationships with women (although not in relationship to the sexually explicit material)
CSB subjects compared to healthy volunteers had significantly more difficulty with sexual arousal and experienced more erectile difficulties in intimate sexual relationships but not to sexually explicit material.
If it was sex addiction they wouldn't have porn induced ED.
The 3 major addiction-related brain changes discussed in YBOP videos & articles: sensitization, desensitization, and hypofrontality.Again, you cannot make these conclusions as they were looking at compulsive sexual behaviour. Not Porn Addiction on its own. There are way too many confounds to state "yes, porn addiction causes these changes."
Both studies controlled for confounds, especially the Cambridge study. Bottom line these studies support the TEDx talk. Fact.
I'm bored with your spin. No one is reading this and everyone knows you are misrepresenting the studies.
