Electroencephalogram (EEG) dataset with porn addiction and healthy teenagers under rest and executive function task

The electroencephalogram (EEG) signal data were obtained from Yayasan Kita dan Buah Hati (YKBH), Jakarta, Indonesia and collected using a Brain Maker EEG machine with 19 channels. The sampling rate of the machine was 250 Hz. Fourteen participants (five females and nine males) participated in the data collection. A psychologist verified that seven of them were addicted to porn, and seven were healthy teenagers. The EEG data were recorded using one protocol with nine tasks for 10 min. The three stages were the baseline (tasks with eyes closed and open), emotional state (happy, calm, sad and fearful tasks) and main (15-words memorisation task, executive task and 15-words recall task) stages. The data obtained was used to analyse the signal pattern of pornography addiction amongst teenagers, as well as the emotional signal pattern and working memory capacity.

Value of the Data
• The dataset is useful for analysing the brain activity in pornography addiction cases through electroencephalogram signals. • The dataset is useful for analysing emotions amongst teenagers through EEG signals.
• The dataset is useful to analyse the working memory capacity amongst teenagers through EEG signals. • The dataset is beneficial for data scientists and psychologists to understand pornography addiction amongst teenagers in detail. • The dataset can be used on different frequency bands and other brain regions to understand the frequency band or the particular brain area that shows the pattern of pornography addiction behaviour.

Data Description
This data in "Brief article" provided detailed information of the electroencephalogram (EEG) dataset with porn addiction and healthy teenagers under rest and executive function tasks [2] . We acquired EEG signal data from Yayasan Kita Dan Buah Hati (YKBH), Jakarta, Indonesia. Data were collected from 14 participants (five females and nine males). Seven of them were confirmed to be addicted, whereas seven were healthy youngsters, based on clinical evaluation by the psychologist. The detailed information on the stimuli, subject details, gender, label, and screening method is presented in the Experimental Design, Materials and Methods section.
The dataset was collected using a Brain Maker device with 19 channels. The channels are P4, O2, P8, T8, C4, Cz, Fz, F4, Fp2, F8, Fp1, F7, F3, C3, T7, P7, P3, O1 and Pz. Each participant had nine different tasks in the raw data, which included eyes closed and open, happy, calm, sad, fear, memorise, executive task and recall with a total of 10 min. EEG signals were acquired using  the Brain Maker with 19 channels. The EEG electrodes were placed on the head, which followed the International 10-20 system, as shown in Fig. 1 . The sampling frequency of the recorded data was 250 Hz. The EEG data of each participant was stored in a .tdms file. The software QtiPlot ( https://www.qtiplot.com/download.html ) was used to convert the .tdms file into .csv file. Table 1 shows the detailed information on raw data, including the task and file names, duration, and array shape. The data array shape was arranged in samples × channels. The length of the data was manually validated by multiplying the sampling frequency with the task duration to obtain samples numbers for each task. For example, the number of samples in the closed-eye task was 250 Hz × 60 s = 15,0 0 0. Each sample had 19 channel signal values in microvolts.
As shown in Fig. 2 , the dataset was stored in a folder named data_porn_addiction. The data_porn_addiction comprised 14 folders that represented the subjects' data, named S1 until S14. Each subject's folder contained several .csv files, such as EC.csv, EO.csv, H.csv, C.csv, S.csv, F.csv, M.csv, ET.csv and R.csv. We also provided detailed information such as channel representation in Channels.jpeg, data acquisition hardware in Device.jpeg, participant labels in Participants.xlsx, and experimental protocols in Protocols_details.xlsx.

Stimuli
In this experiment, we used two stimuli. The first stimulus is the emotional state of the IAPS [1] . The stimulus showed images related to emotions, including happy, calm, sad and fearful. Image of each emotion was displayed for 1 min. Another stimulus was the executive task,  showing pornographic images. The images were provided by a psychologist. We chose both stimuli because we wanted to know the brain activity of porn-addicted and non-porn-addicted subjects. Based on EEG signals collected in several emotional states using IAPS's standard procedure, we inferred the emotional state of the subjects during the executive task.

Subject
The data collection process included 14 participants with ages varying between 13 and 15 years. Table 2 presents the participants' details. The psychologist verified that out of 14 subjects, seven were porn-addicted, while the rest seven did not have porn addiction using the Youth Pornography Addiction Screening Tool (YPAST) [ 3 , 4 ], which is a free on-line initial screening assessment tool for adolescents aged 12 to 18 years with potential addiction to pornography. The subjects answered each of the 25 questions by choosing one of the five possible responses. Moreover, the psychologist interviewed the participants and their parents to assess the YPAST results. By analysing both instrument results, the psychologist concluded the participant label or category.

Protocols
As shown in Fig. 3 , the participant watched the visual stimulus from the monitor by wearing the Brain Maker device. The protocol for controlling the visual stimulus by an administrator is presented in Table 3 . Signals were collected when the participant was performing the task. Fig. 4 shows the Brain Maker device used in this experiment.
The three experimental stages comprised a total of nine tasks. The experiment duration for each participant was 10 min. Table 3 shows the task names and duration for each stage. The three stages included the baseline, emotional state and main stages. The baseline stage consisted of tasks with eyes open and eyes closed. In the emotional state stage, each of the happy, calm, sad and fearful states were collected for 1 min with IAPS [1] as the stimulus. It provided a set of coloured photographs of the normative emotional stimulus. The monitor showed a picture to elicit a happy, calm, sad or fearful emotion in the participants. In the "Memorise 15 words" task, the participant watched 15 words displayed individually on the monitor for 1 min. Each participant was instructed to remember all displayed words. In the executive task, the participant watched a series of images containing pornography items validated by a psychologist, for 2 min. In the recall task, the participants were asked to spell the 15 words given in the "Memorize 15 words" task in 1 min while watching a white blank screen.

Ethics Statement
This study was approved by Taylor's University (HEC 2020/035). The ethics committee approved all questionnaires and tasks for the participants. The parents and legal tutors of the children received written information about this research and a consent form. The participants and their legal tutors read and signed the consent form before the experiment. The EEG device on the participant's head did not cause any pains or injections or both. Consequently, the participants completed the experiment safely. The study was conducted according to the guidelines of the Code of Ethics of the World Medical Association (Declaration of Helsinki) and approved by the Ethical Committee Taylor's University Malaysia
