A recent study has revealed that pornography can be more rewarding for an adult male compared to other internet addictions like gambling and video gaming. The research published in Human Brain Mapping claimed that the human brain gets conditioned to stimuli from three common internet-based addictions: pornography, gambling, and video gaming.

The study involved an experiment where 31 right-handed male participants (all under the age bracket of 19-38) chose between pornographic images, video game screenshots, and pictures of money. All three choices were paired with a small cash reward.

Using a classical conditioning approach inside an MRI scanner, neutral stimuli (geometric figures) were paired with rewarding images (pornography, gaming, or money) to form associations. This was done repeatedly over 68 trials, with the neutral stimulus occasionally followed by the reward. The aim was to observe how the brain learns to connect neutral stimuli with rewards.

Three methods were used to measure the responses. Firstly, a subjective rating of the candidates was taken to determine the height of arousal and pleasure towards each stimuli before and after the conditioning process.

Secondly, skin conductance responses (SCR) were recorded to calculate the physiological stimulation of the participants by monitoring the alterations in sweat gland activities. This process helped the researchers in estimating the physical arousal of the participants through the nervous system response.

Finally, to conclude the experiment, a functional MRI scan of the participants was taken to record brain activity and neural correlates of reward processing. This technique provided a deeper understanding of the neural mechanisms driving the participant's responses. It allowed the researchers to observe the response of different brain regions to the stimuli. The fMRI scans gave a detailed overview of the brain activity.

As per the final data of the research pornographic images came out to be most arousing and pleasant compared to gaming and money. The study focused on understanding the brain's behaviour to internet-related rewards in a healthy context.\
