EEG and event-related potentials in matching-to-sample and conditional discrimination

• Event-related potentials (ERPs) during matching-to-sample (MTS) reflect differences associated with programmed consequences in conditional discrimination training.¹
• A 64-channel wet-electrode EEG system at 1,024 Hz was used to record continuously from participants in a three-phase MTS paradigm.¹
• MTS training and testing were customized with PsychoPy and used 12 arbitrarily related abstract stimuli.¹
• Feedback-driven ERPs in conditional discrimination provide direct electrophysiology and neural time-series methods for studying reinforcement and stimulus relations.^{1 1}
