Scatter plots demonstrating the relationship in non-abusing controls between scores as summed from the Chapman Physical and Social Anhedonia scale and the amplitudes of the N2 and P3 waveforms, as well as scatter plots demonstrating the relationship between amplitude of the Pe waveform and reaction time. Higher levels of anhedonia were associated with more robust, negative N2 waveforms. Higher levels of anhedonia were also associated with lower amplitudes in the P3. Lower Pe amplitudes were associated with slower reaction times and more post error slowing.
