Arm Intervention/treatment
Experimental: validation of EEfRT task
20 healthy volunteers will be recruted to validate motivation EEfRT task which is adaptated to HR-EEG
Other: HR-EEG
Experimental: biomarkers identification
20 addict online poker gamblers and 20 non-addict online poker gamblers will be recruted : After standardized questionnaires to define the socio-demographic data, the diagnosis of gambling addiction (Diagnostic and Statistical Manual of Mental Disorder 5th edition DSM-5), screening for comorbidities addictive, the level of anxiety and impulsivity, brain acvtivity will be registred (by randomisation between the 2 tasks) with HR-EEG: during the performance of a task of motivation evaluation laboratory (EEfRT) adaptated for high-resolution electroencephalography AND during a laboratory task that assesses decision making in conditions of uncertainty (IGT) with its version for high-resolution electroencephalography has already been validated in a previous study (Giustiniani et al., 2015).
Other: HR-EEG
Experimental: biomarkers validation
13 online poker gamblers will be recruted, independently of their dependance profile and they will realize the same task that in precedent arm (quaestionnaires and 2 tasks adaptated to HR-EEG).
Other: HR-EEG

Primary Outcome Measures :
  1. average activation for each functional neuroimaging examination [ Time Frame: day 7 ; day 14 ]

Secondary Outcome Measures :
  1. correlations between various examinations and strength of neuronal response [ Time Frame: day 7 ; day 14 ]
    a subject-by-subject analysis of each brain activation will be conducted to look for correlations between the various examinations and strength of neuronal response.
