Objective: The neurocognitive risk mechanisms predicting divergent outcomes likely differ between men and women who use cannabis recreationally. Increasingly, the of descriptive distributions including ex-Gaussian has been applied to draw stronger inferences about health in clinical populations. current project examines whether long tail reaction times (RTs) a distribution, as characterized by parameter tau which may represent difficulty with regulation arousal, predicts problematic 6 months later those recreationally, sex moderates these prospective associations. Method: Young adults (ages 18-30, mean age 20.5 years, N =159, 57.2% women, 69.2% Caucasian) recreationally used either occasionally (at least once per month) or frequently (three more week) completed Stroop Color-Word Task at baseline. Ex-Gaussian was estimated for each participant. Self-report hazardous (CUDIT-R) dysregulation negative (DERS) positive emotions (DERS-Positive) were obtained baseline 6-month follow-up. Results: For larger baseline, being man (but not woman) associated increased regulating concurrently (b = -0.01, F (1,159) 5.48, p 0.02), six -0.007, 4.42, 0.037) after controlling use. Conclusions: Excessively RTs during cognitive performance help characterize use, contributes understanding between-sex heterogeneity pathways towards disorders.

Addictions have recently been classified as substance use disorder (SUD) and behavioral addiction (BA), but the concept of BA is still debatable. Therefore, it necessary to conduct further neuroscientific research understand mechanisms same extent SUD. The present study used machine learning (ML) algorithms investigate neuropsychological neurophysiological aspects addictions in individuals with internet gaming (IGD) alcohol (AUD). We developed three models for distinguishing IGD from those AUD, healthy controls (HCs), AUD HCs using ML algorithms, including L1-norm support vector machine, random forest, logistic regression (LR). Three distinct feature sets were model training: a unimodal-electroencephalography (EEG) set combined sensor- source-level feature; unimodal-neuropsychological (NF) included sex, age, depression, anxiety, impulsivity, general cognitive function, multimodal (EEG + NF) set. LR classification outperformed other (accuracy: 0.712). important features selected by highlighted that group had differential delta beta source connectivity between right intrahemispheric regions sensor-level EEG activities. Among NFs, sex age good performance. Using techniques, we demonstrated similarities differences (a BA) SUD).
