摘要: High sensitivity of the Behavioral Approach System (BAS) was shown to be one strongest predictors substance use (SU). It hypothesized that individuals with high BAS would experience higher emotional arousal in reward expectancy situation and lower punishment than low activity. The level indicated by theta spectral power, general cortical excitability frequency oscillations (HFO), were measured a sample young people who filled out Carver White's Inhibition System/Behavioral (BIS/BAS) scales. Frontal HFO increased scorers during expectation decreased punishment. In powers increased, contrary those for cue, cue. Theta-gamma coupling Drive (those above median) appeared below median split on this scale) situation.
